In the multiple illumination source hybrid control, the operation modes may include an individual illumination source operation mode, a multiple illumination source time-sharing alternating operation mode, and a multiple illumination source hybrid operation mode. The switch 2 can be used for controlling one of the illumination sources to work independently or part of the illumination sources to work alternately in a time-sharing way, or the illumination sources can work together. It will be appreciated that the type of operation mode that can be determined according to the actual application is not limited to the above modes.
In a specific implementation, the output end of the change-over switch 2 is connected with the input end of the driving device 4, when the change-over switch 2 is closed, a passage is formed between the power supply 1 and the illumination source, and the driving device 4 starts to work so as to drive the illumination source to work. It will be appreciated that the specific configuration of the drive device 4 may be determined according to the different illumination source types that need to be controlled.
In one embodiment, the number of illumination sources may be two, the illumination sources being HID and LED, respectively. For the type of illumination source to be HID, it is necessary to correspond to the HID driving device 41 capable of starting HID operation; for the type of illumination source to be LEDs, a corresponding LED driving device 42 is required which is capable of enabling the operation of the LEDs. The driving device may thus be a plurality, the specific number being determined by the number of illumination sources to be controlled.

In a specific implementation, the man-machine interaction device 31 sends the trigger signal by way of inputting the control mode setting value and the manual setting value. The singlechip 34 in the control module 3 receives the trigger signal sent by the man-machine interaction device 31, so as to control the illumination source to start working according to the information contained in the trigger signal.
It should be noted that, the control mode set point determines whether to use an automatic control mode or a manual control mode for the hybrid lighting control device, when the input control mode set point represents the automatic control mode, the manual set point is not required to be input any more, and the singlechip 34 in the control module 3 can determine the working modes of a plurality of lighting sources according to the actual situation, and does not need to be judged according to the manual set point; when the input control mode set point indicates a manual control mode, then the manual set point needs to be continuously input to determine the working modes of the plurality of illumination sources.

As shown in fig. 2, the control module 3 further comprises a display device 33 for displaying the environmental parameter data. The display device 33 may display the environmental parameter data collected by the collecting device 32; the display mode can be real-time display or interval display. For example, real-time display can be performed for time parameters; for the temperature parameter, since the temperature change is slow in one day, display at every hour intervals may be employed. The user can more conveniently check the environmental parameter data through the display equipment, and the user can conveniently adjust the working mode of the hybrid lighting device according to the environmental parameter data.
FIG. 3 is a flowchart of a method for controlling mixed illumination according to an embodiment of the present invention; as shown in fig. 3, the hybrid lighting control device includes:
S10: acquiring a trigger signal used for representing entering into a working mode;
s11: determining an adopted working mode according to the trigger signal;
S12: the change-over switch 2 is controlled accordingly to switch on or off the power supply and the plurality of illumination sources depending on the operation mode.
In a specific implementation, as shown in fig. 2 and 3, when the control module 3 receives the trigger signal, the mixed lighting control device is characterized to start working. The trigger signal may include control mode information and working mode information, where the control mode information is used to determine whether the hybrid lighting control device adopts an automatic control mode or a manual control mode, for example, a header of data corresponding to the trigger signal may be set to 1, which indicates that the hybrid lighting control device adopts the automatic control mode; setting the header of the data corresponding to the trigger signal to 0 indicates that the manual control mode is adopted.
The operation mode information is used to determine which operation mode is used, such as a single operation mode, a time-sharing alternating mode, and a hybrid operation mode. Specifically, the operation mode information such as the single operation mode, the time-sharing alternate mode, the hybrid operation mode and the like can be represented by the mode of setting the data bit value corresponding to the trigger signal.
In step S11, the singlechip 34 in the control module 3 determines the working mode to be adopted according to the trigger signal. In one embodiment, after acquiring the trigger signal, the singlechip 34 in the control module 3 first parses the trigger signal; the analysis result contains control mode information, and whether an automatic control mode is adopted or not is judged according to the control mode information; if so, the environmental parameter data is collected by the collecting device 32, the collected environmental parameter data is read and analyzed, and the working mode is determined according to the analysis result. For example, in the automatic control mode, if the lighting source to be controlled is specifically an HID and an LED, the collected environmental parameter data may be determined as the environmental light intensity data and the environmental temperature data, considering that the HID can provide light and heat at the same time, and the LED has a good light supplementing effect and is energy-saving and environment-friendly. When the light intensity is weak and the temperature is low, a mode of controlling the HID to work can be adopted, and the light supplementing can supplement heat at the same time; when the light intensity is weak but the temperature is high, a mode of controlling the LED to work can be adopted, so that the light intensity requirement is met and the energy consumption is reduced.
If the manual control mode is adopted, the manual setting value is read, namely, the working mode information contained in the trigger signal is acquired, and the working mode is determined according to the manual setting value. For example, the illumination sources are HID and LED, and when the manual setting value is 0Xa0, the operation mode is determined to be HID independent operation mode; when the manual set value is 0Xa1, determining that the working mode is an LED independent working mode; when the manual set value is 0Xa2, determining that the working mode is an HID and LED time-sharing alternating working mode; when the manual setting value is 0Xa3, the working mode is determined to be an HID and LED mixed working mode.
In step S12, the changeover switch 2 may be controlled accordingly to switch on or off the power supply 1 and the plurality of illumination sources depending on the determined operation mode. Specifically, as shown in fig. 2, when in the HID independent operation mode, the first switch 21 in the control changeover switch 2 is turned on, and the second switch 22 is kept in an off state, so that the connection between the power supply 1 and the HID driving device 41 is established, and the HID is driven to operate normally; when the LED and the power supply are in the time-sharing alternating working mode, the first switch 21 is firstly turned on, the second switch 22 is kept in an off state, the connection between the power supply 1 and the HID driving device 41 is established to enable the HID to start working, after the preset time is reached, the first switch 21 is controlled to be turned off, the second switch 22 is turned on, the connection between the power supply 1 and the LED driving device 42 is established to enable the LED to start working, and after the preset time is reached again, the steps are repeated to switch, so that the time-sharing alternating working of the HID and the LED is achieved; it should be noted that, the preset time is specifically variable, and the working time of the HID and the LED can be adjusted according to the actual application situation, without ensuring that the working time of the HID and the LED is equal. When the power supply is in the HID and LED mixed working mode, the first switch and the second switch are controlled to be simultaneously turned on, and the power supply 1 is respectively connected with the HID driving device 41 and the LED driving device 42 to complete the HID and LED mixed working.
According to the mixed illumination control method provided by the invention, the working modes of a plurality of illumination sources are determined through the control module, and the plurality of illumination sources are respectively switched on or off by utilizing the change-over switch according to the working mode requirement. Therefore, the working mode adopted by the illumination sources can be flexibly determined according to actual situation requirements, and the switching on and off of the illumination sources are controlled by utilizing the change-over switch, so that the mixed control of the illumination sources is realized, the high-efficiency switching of the illumination sources is completed, the application effect of the illumination system can be better exerted by combining the advantages of different illumination sources, and the requirements of the illumination system in different projects are met.
In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in further detail below in connection with an application scenario of supplementing light with an illumination source in agriculture. Fig. 4 is a flowchart of another method for controlling mixed illumination according to an embodiment of the present invention. As shown in fig. 4, another hybrid lighting control method provided by an embodiment of the present invention includes:
S111: analyzing the trigger signal;
S112: judging whether an automatic control mode is adopted according to the control mode information contained in the analysis result; if so, go to step S113; if not, the process advances to step S114.
It will be appreciated that in agricultural applications, different degrees of light and heat compensation may be performed depending on the season, whereby the environmental parameter data is specifically temperature data and date and time data; the illumination sources may be HID and LEDs in particular.
In step S113, the current season can be detected according to the collected date and time data, and different working modes can be selected according to the seasons.
If the current winter is detected, judging whether the temperature data is lower than the set temperature data or not; it should be noted that the set temperature data may be set according to a temperature suitable for growing crops in agriculture, and the present invention is not limited thereto. If the temperature data is lower than the set temperature data, the operation of light supplementing and heat supplementing in the environment can be analyzed, so that the working mode is determined to be an HID independent working mode; if the temperature data is higher than the set temperature data, the condition that the light supplementing operation is needed in the environment can be analyzed, and the working mode is determined to be an HID and LED time-sharing alternating mode because the temperature is generally lower in winter and the temperature difference is larger so as to ensure that the environment temperature can continuously reach the set temperature data.
If the current spring or autumn is detected, the working mode can be determined to be an HID and LED mixed working mode because the temperature and the light intensity in the two seasons do not belong to the strongest time. Specifically, by selecting the HID with proper power, the temperature data in the environment after the operation of the HID can be ensured to reach the set temperature data requirement. After the selected HID is determined, the requirement on the environment light intensity is met by selecting an LED with proper power.
If the current summer is detected, judging whether the temperature data is lower than the set temperature data or not; if the temperature is lower than the set temperature data, considering that the temperature is generally higher throughout the summer, the working mode can be determined to be an HID and LED time-sharing alternating mode, so that the energy consumption is saved while the requirements of the temperature and the light intensity are met; if the temperature data is higher than the set temperature data, the working mode is determined to be an LED independent working mode, and only the current environment is supplemented with light.
In step S114, the manual setting value is read, and the operation mode is determined according to the manual setting value. In this embodiment, when the manual setting value is 0Xa0, the operation mode is determined to be the HID independent operation mode; when the manual set value is 0Xa1, determining that the working mode is an LED independent working mode; when the manual set value is 0Xa2, determining that the working mode is an HID and LED time-sharing alternating working mode; when the manual setting value is 0Xa3, the working mode is determined to be an HID and LED mixed working mode.
The other mixed illumination control method provided by the embodiment of the invention comprises the following steps:
s115: controlling the HID driving device 41, the LED driving device 42 and the change-over switch 2 to carry out corresponding working states;
s116: the control module 3 controls the display device 33 to display information.
In step S115, the change-over switch 2 is controlled to be adjusted to a corresponding state according to the determined operation mode, so that the HID driving device 41 and/or the LED driving device 42 are turned on to drive the corresponding illumination source to operate.
In step S116, the control module 3 controls the display device 33 to display the collected temperature data and time-date data, so that the user can more conveniently view the current temperature information and time-date information through the display device 33.
