Detailed Description
In order to make the technical solutions of the present invention better understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
It should be noted that the terms "first," "second," and the like in the description and claims of the present invention and in the drawings described above are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the invention described herein are capable of operation in other sequences than those illustrated or described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
Fig. 1 is a schematic structural diagram of an oven control system according to an embodiment of the present invention, and referring to fig. 1, the oven control system according to the embodiment includes: cooling module 110, control module 120, pipeline 130 and at least two thermostats 140; the cooling module 110 is connected with each thermostat 140 through a pipeline 130, and the cooling module 110 is used for conveying a refrigerant to the thermostats 140 through the pipelines 130; each thermostat 140 includes a first solenoid valve connected to the pipe 130; the control module 120 is connected to the cooling module 110 and each of the incubators 140, and the control module 120 is configured to control a first electromagnetic valve in one of the incubators 140 to be turned on after the cooling module 110 is started, so that the incubator 140 receives the refrigerant transmitted by the cooling module 110, and simultaneously control the incubators 140 to be in a temperature adjustment state and the first electromagnetic valves in the remaining incubators to be turned off, where the remaining incubators are other incubators 140 of at least two incubators 140 except the incubator 140 that receives the refrigerant.
Specifically, the material of the pipe 130 may be copper. The pipe 130 in this embodiment is used for transmitting a refrigerant, rather than cold air, compared with a pipe for transmitting cold air, the pipe 130 for transmitting a refrigerant provided in this embodiment is not limited by an installation space, and the pipe 130 for transmitting a refrigerant has no high requirement on the diameter of the pipe, so that the cost can be reduced.
The cooling module 110 may output a refrigerant after being activated. The refrigerant may affect the actual temperature within oven 140. Oven 140 may generate cool air upon receiving the refrigerant, thereby lowering the actual temperature within oven 140.
When a plurality of thermostats 140 all need cooling module 110 to convey the refrigerant, control module 120 controls the first electromagnetic valve in one of thermostats 140 to be switched on, and controls the first electromagnetic valve in the remaining thermostats to be switched off at the same time, so that the refrigerant is conveyed to the thermostats 140 in which the first electromagnetic valve is switched on, and cannot be conveyed to the thermostats 140 in which the first electromagnetic valve is switched off, thereby enabling cooling module 110 to output the refrigerant only used by one thermostats 140, and the refrigerant needed by a plurality of thermostats 140 is not required to be output by cooling module 110 at the same time, thereby the cooling module 110 with large power consumption is not required, and the cost of the thermostat control system can be reduced.
When the cooling module 110 delivers the refrigerant into one oven 140, the first solenoid valves in the remaining ovens are closed, and the gas or the refrigerant in the ovens 140 is not transmitted into the other ovens 140 through the first solenoid valves and the pipeline 130, so that the actual temperatures in the ovens 140 are not affected by each other. In addition, since temperature lowering module 110 individually delivers the refrigerant to incubators 140, the preset temperatures of incubators 140 may be different, so that each incubator 140 satisfies different preset temperature requirements.
When thermostat 140 is in the temperature regulation state, the compressor and the condenser inside thermostat 140 work, can reduce the actual temperature in it, and it is visible that this embodiment sets up cooling module 110 and thermostat 140 and adjusts the actual temperature in thermostat 140 jointly to accelerate actual temperature's regulation rate.
Since the oven control system provided in this embodiment can control the actual temperature inside oven 140, so as to maintain the actual temperature inside oven 140 at a constant value, oven 140 in this embodiment can test the performance of the test object at a constant temperature, for example, the test object may be a battery.
The present embodiments provide an incubator control system in which a cool down module can deliver refrigerant to an incubator through a conduit after startup. The control module controls the first electromagnetic valve in the thermostat to be switched on and then enables the refrigerant to be transmitted into the thermostat, and meanwhile the thermostat which is switched on by the first electromagnetic valve is controlled to be in a temperature adjusting state, so that the thermostat can adjust the temperature of the thermostat. After the control module controls the first electromagnetic valve in one thermostat to be switched on, the control module simultaneously controls the first electromagnetic valves in the rest thermostats to be switched off, so that the thermostats with the first electromagnetic valves switched off cannot receive the refrigerant. Because the cooling module only conveys the refrigerant to a thermostated container, consequently, can set up the lower cooling module of consumption to reduce the cost of cooling module. When the first electromagnetic valve in one thermostat is set to be switched on, the first electromagnetic valves in the rest thermostats are closed, so that the actual temperature in each thermostat is not influenced by each other. In summary, the thermostat control system provided in this embodiment can reduce the cost and make the actual temperatures in the thermostats not affect each other.
On the basis of the above embodiment, optionally, fig. 2 is a schematic structural diagram of an incubator provided according to an embodiment of the present invention, and referring to fig. 2, each incubator 140 includes a first evaporation unit 141; the input end of the first evaporation unit 141 is connected with the first electromagnetic valve 142, and the output end of the first evaporation unit 141 is connected with the cooling module 110.
Specifically, the first evaporation unit 141 includes a first evaporator and a plurality of second electromagnetic valves 10, and the model of the second electromagnetic valves 10 may be the same as that of the first electromagnetic valve 142. The input end of the first evaporation unit 141 is connected only with the first electromagnetic valve 142 in the incubator 140 where the first evaporation unit 141 is located, and the first evaporation unit 141 is located in the box body of the incubator 140. The first evaporation unit 141 may output cool air upon receiving the refrigerant, thereby lowering an actual temperature inside the oven 140.
On the basis of the above embodiment, optionally, with continued reference to fig. 2, each incubator 140 further includes a first refrigeration unit 143, a first condensation unit 144, a second evaporation unit 145, a heating unit, a control unit, and a plurality of temperature sensors; the first refrigeration unit 143 is connected to the first condensation unit 144 and the second evaporation unit 145; the first condensing unit 144 is connected with the second evaporating unit 145; a plurality of temperature sensors are respectively located at different positions within incubator 140; the control unit is connected with the control module, the heating unit, the first refrigerating unit 143, the first condensing unit 144, the second evaporating unit 145, and the plurality of temperature sensors.
Specifically, the first cooling unit 143 includes a compressor, the first condensing unit 144 includes a condenser, the second evaporating unit 145 includes a second evaporator, and the heating unit includes a heater and a fan. The first cooling unit 143 and the first condensing unit 144 cooperate to generate a refrigerant, and the second evaporating unit 145 receives the refrigerant to generate cold air, thereby lowering the actual temperature inside the oven 140. When the actual temperature in the oven 140 reaches the preset temperature with the help of the cooling module 110, the first solenoid valve 142 in the oven 140 is closed, and the control unit in the oven 140 controls the first cooling unit 143, the first condensing unit 144, the second evaporating unit 145 and the heating unit to continue to operate to maintain the actual temperature in the oven 140 in a constant state. The temperature sensor is used to detect the temperature inside oven 140, and a plurality of temperature sensors are provided to detect actual temperatures at different positions inside oven 140. The final actual temperature of the oven 140 may be an average value of the temperatures measured by the plurality of temperature sensors, a lowest temperature among the plurality of temperatures measured by the plurality of temperature sensors, a highest temperature among the plurality of temperatures measured by the plurality of temperature sensors, or the like.
Optionally, fig. 3 is a schematic structural diagram of a cooling module connected to a plurality of incubators according to an embodiment of the present invention, and referring to fig. 3, the cooling module 110 includes a second refrigeration unit 111 and a second condensation unit 112; the second refrigeration unit 111 is connected with the second condensation unit 112 and the first evaporation unit 141; the second condensing unit 112 is connected to the first solenoid valve 142 of each of the incubators 140 through the pipe 130.
Specifically, the second cooling unit 111 includes a compressor, and the power consumption of the second cooling unit 111 may be greater than that of the first cooling unit, thereby facilitating rapid cooling of the incubator 140. The second condensing unit 112 includes a condenser, and the second cooling unit 111 and the second condensing unit 112 work together to generate a refrigerant, which may be transferred to the first evaporating unit 141 in each of the incubators 140 through the pipe 130.
It should be noted that, although one cooling module 110 in fig. 3 is connected to four thermostats 140, the present invention is not limited thereto, and in practical applications, the number of thermostats 140 may be set according to actual requirements.
Fig. 4 is a schematic structural diagram of another incubator control system according to an embodiment of the present invention, and referring to fig. 4, the control module 120 includes an actual temperature obtaining unit 121, a preset temperature obtaining unit 122, and a cooling control unit 123; an actual temperature acquisition unit 121 for acquiring an actual temperature inside each incubator 140; the preset temperature obtaining unit 122 is configured to obtain a preset temperature of each thermostat 140; the cooling control unit 123 is connected to the preset temperature obtaining unit 122, the actual temperature obtaining unit 121, and the cooling module 110, and the cooling control unit 123 is configured to control the cooling module 110 to start when a difference between the actual temperature of the at least one thermostat 140 and the preset temperature exceeds a set threshold.
Specifically, the preset temperature is a temperature that needs to be reached by the thermostat 140, and a user can determine the preset temperature of each thermostat 140, and the actual temperature is the current temperature of the thermostat 140 and can be measured by the temperature sensor. The actual temperature acquisition unit 121 is connected to each temperature sensor inside the oven 140. If the difference between the actual temperature in the oven 140 and the preset temperature exceeds the preset threshold, a long time is required for cooling only by the oven 140, and therefore, the oven 140 and the cooling module 110 are required to be cooled together, so as to ensure that the actual temperature in the oven 140 reaches the preset temperature quickly. When at least one thermostat 140 requires the cooling module 110 to assist in cooling, the cooling control unit 123 controls the cooling module 110 to start, so that the cooling module 110 can output a refrigerant, and the first evaporation unit in the thermostat 140 can reduce the actual temperature in the thermostat 140 after receiving the refrigerant.
It should be noted that when the difference between the actual temperature in oven 140 and the preset temperature exceeds the set threshold, the actual temperature in oven 140 is greater than the preset temperature.
On the basis of the above embodiment, optionally, with continued reference to fig. 4, the control module 120 further includes a first solenoid valve control unit 124; the first solenoid valve control unit 124 is configured to control the first solenoid valve in each oven 140 to be turned on or off, and is further configured to control the first solenoid valve in the oven 140 to be turned off after a set time delay when a difference between an actual temperature of the oven 140 receiving the refrigerant and a preset temperature is within a set range.
Specifically, the first solenoid valve control unit 124 is connected to the first solenoid valve in each oven 140. The first solenoid valve control unit 124 controls the first solenoid valve in one oven 140 to be turned on and controls the first solenoid valves in the remaining ovens to be turned off. When the difference between the actual temperature and the preset temperature is within the set range, it indicates that the current actual temperature of the oven 140 reaches the temperature requirement of the oven 140, which needs to be constantly maintained, and the set range includes 0 ℃.
Because the actual temperature in the oven 140 is measured by the temperature sensor, the temperature measured by the temperature sensor cannot represent the temperature at all positions in the oven 140, when the difference between the actual temperature measured by the temperature sensor and the preset temperature is within the set range, the temperature of some pipes, devices and the like in the oven 140 is still greater than the preset temperature, if the difference between the actual temperature measured by the temperature sensor and the preset temperature is within the set range, the first electromagnetic valve is closed, and the pipes, the devices and the like can raise the actual temperature in the oven 140 after the first electromagnetic valve is closed, so as to increase the working loads of the first refrigeration unit, the first condensation unit and the second evaporation unit. Therefore, by closing the first solenoid valve after delaying the set time period, it is possible to ensure that the temperatures at a plurality of positions in thermostat 140 reach the preset temperature. The set time period may be 90s, and in practical applications, the set time period may be determined according to a preset temperature, a volume of the oven 140, and the like.
Optionally, with continued reference to fig. 4, the control module 120 includes a fault detection unit 125; the fault detection unit 125 is connected to the cooling module 110, the first solenoid valve control unit 124, and the thermostat 140, and the fault detection unit 125 is configured to detect whether the cooling module 110 has a fault, and send fault information to the thermostat 140 and the first solenoid valve control unit 124 when the cooling module 110 has a fault.
Specifically, if the cooling module 110 malfunctions, the cooling module 110 cannot supply the refrigerant to the oven 140 any more. The fault detection unit 125 may further be connected to the cooling control unit 123, and when the fault detection unit 125 detects that the cooling module 110 has a fault, the cooling control unit 123 may control the cooling module 110 to be turned off. The first solenoid valve control unit 124 may control the first solenoid valve in each of the incubators 140 to be closed after receiving the failure information. After receiving the fault information, the thermostat 140 may be controlled to be in a temperature adjustment state, so that the thermostat 140 independently adjusts the actual temperature therein, and finally the difference between the actual temperature and the preset temperature is within the set range. Therefore, the thermostat control system provided by the embodiment can still ensure that the thermostat 140 continues to cool when the cooling module 110 fails.
Optionally, with continued reference to fig. 4, the control module 120 includes a wait duration prediction unit 126; the waiting time period predicting unit 126 is used to predict the waiting time period until the first solenoid valve of the thermostat 140 that needs to receive the refrigerant among the remaining thermostats is turned on.
Specifically, the waiting duration prediction unit 126 is connected to the actual temperature acquisition unit 121 and the preset temperature acquisition unit 122, the waiting duration prediction unit 126 acquires the actual temperature in the thermostat 140 that is receiving the refrigerant transmitted by the cooling module 110 in real time, predicts when the first electromagnetic valve of the thermostat 140 that is cooling can be closed according to the cooling rate, and then determines the waiting duration before the first electromagnetic valve in each thermostat 140 is turned on according to the turn-on sequence of the first electromagnetic valves in the remaining thermostats. Illustratively, the thermostat control system includes 4 thermostats 140, the numbers a, b, c, and d of the 4 thermostats 140 are respectively set, and the conduction sequence of the first electromagnetic valves in the 4 thermostats 140 is b, c, d, and a, so that the cooling module 110 first supplies the refrigerant to the thermostat 140 with the number b, then supplies the refrigerant to the thermostat 140 with the number c, then supplies the refrigerant to the thermostat 140 with the number d, and finally supplies the refrigerant to the thermostat 140 with the number a. When oven 140, numbered b, is receiving the refrigerant delivered by cooling module 110, the waiting time period required before the first electromagnetic valve of oven 140, numbered c, is turned on is the time period required before the first electromagnetic valve of oven 140, numbered b, is turned off, and the waiting time period required before the first electromagnetic valve of oven 140, numbered d, is turned on is: the time period for which the first solenoid valve of oven 140, numbered b, is closed plus the time period for which the first solenoid valve of oven 140, numbered c, needs to be on. The waiting time period required before the first electromagnetic valve of the thermostat 140 with the number a is turned on is as follows: the distance the first solenoid valve of oven 140, numbered b, is closed, plus the length of time the first solenoid valve of oven 140, numbered c, needs to be on, plus the length of time the first solenoid valve of oven 140, numbered d, needs to be on.
Optionally, fig. 5 is a schematic structural diagram of another incubator control system according to an embodiment of the present invention, and referring to fig. 5, the incubator control system provided in this embodiment further includes an instruction receiving module 150; the instruction receiving module 150 is connected to the control module 120, and the instruction receiving module 150 is configured to receive a preset temperature of each oven 140 input by a user.
Specifically, the instruction receiving module 150 may be a touch display unit, or may be a key control unit. The user can input the preset temperature of each oven 140 through the command receiving module 150, and the control module 120 can acquire the preset temperature of each oven 140 from the command receiving module 150. The instruction receiving module 150 may be connected to the preset temperature obtaining unit 122 in the control module 120, and may also be connected to the first solenoid control unit 124. The instruction receiving module 150 may further receive another instruction sent by the user, for example, when an oven 140 is receiving the refrigerant conveyed by the cooling module 110, the user sends an oven switching instruction to the instruction receiving module 150, the instruction receiving module 150 sends the received oven switching instruction to the control module 120, the control module 120 controls the first electromagnetic valve of the oven 140 that is currently receiving the refrigerant to close according to the oven switching instruction, and then opens the first electromagnetic valve of the oven 140 that is required to be cooled in the oven switching instruction, so that the oven 140 that is required to be cooled can receive the refrigerant.
