Description
Technical Field
The invention relates to the technical field of sensors, in particular to a parameter configuration method.
Background
The two-wire sensor is typically powered by 24V (15-30V), the loop outputs a 4-20mA signal, 4mA represents the minimum value of the sensor measurement range, 20mA represents the maximum value of the range, the current changes between 4-20mA, the change in the measurement range represents the change in the measurement value, and if the range value is known, the measurement value can be calculated by the sensor output current.
Currently, most two-wire sensors have a unique fixed range, and many sensors are sealed by welding or glue filling processes, so that parameter debugging is difficult once production is completed. The sensor is easy to have problems of parameter drift and low precision after long-term use, and at the moment, if the parameters are forcedly changed, physical damage is required to the sensor shell or the internal structure, and the internal circuit of the sensor is easy to be damaged.
In the prior art, if parameters are to be changed after the sensor is sealed or shipped, a complex control circuit is generally required to be added and implemented based on the HART protocol. Wherein, the HART protocol adopts FSK frequency shift keying signals based on Bell202 standard, and the audio digital signals with the amplitude of 0.5mA are superimposed on the low-frequency 4-20mA analog signals for bidirectional digital communication, and the data transmission rate is 1.2kbps. Because the average value of the FSK frequency shift keying signal is 0, the size of the analog signal transmitted to the control system is not influenced, and the compatibility with the existing analog system is ensured. The main variables and control information in HART protocol communication are transmitted by 4-20mA, and additional measurement, process parameters, device configuration, calibration, diagnostic information is accessed through the HART protocol, if necessary.
However, applications of the HART protocol typically require a dedicated HART modem and a dedicated 4-20mA current conversion chip, and are equipped with dedicated hand-held operators to configure the parameters. If only the simple parameters are modified, the whole circuit is complex, the power consumption is increased and the total volume of the sensor is increased due to the arrangement of the current conversion chip of the control circuit; in addition, the dedicated HART hand-held device is expensive, resulting in high cost of parameter configuration.

Example 2:
as shown in fig. 1, a parameter configuration method is implemented based on a parameter configuration system; the parameter configuration system comprises a detection device and a host, wherein the detection device is electrically connected with the host; the parameter configuration method is used for configuring original parameters of the detection device;
specifically, in this embodiment, the detection device includes a sensor, a processor, and a loop power supply circuit that are electrically connected in sequence, where the loop power supply circuit is electrically connected to the host; the detection device further comprises a power circuit, wherein a controlled end of the power circuit is electrically connected with the loop power supply circuit, and a power output end of the power circuit is electrically connected with the sensor and the processor; the parameter configuration method is used for configuring the original parameters of the sensor in the detection device. Specifically, the sensor in this embodiment is a two-wire sensor, and the general two-wire sensor can be connected to the host computer.
The detection device in this embodiment may be implemented by using a vibration sensor in application number 202021273587.0 and a host electrically connected to the vibration sensor. Specifically, the sensor may be, but not limited to, implemented using a MEMS (Micro-Electro-Mechanical System, microelectromechanical system) acceleration sensor of model KX126-1063, which is configured to receive the vibration signal, convert it into a digital signal, and send it to the processor. The processor is used for acquiring the digital signal sent by the sensor, converting the digital signal into vibration displacement data and then sending the vibration displacement data to the loop power supply circuit; the processor is also used for controlling the working mode of the sensor; in this embodiment, the processor may be implemented by, but not limited to, a processor model STM32L432 KB. The loop power supply circuit is used for receiving the vibration displacement data sent by the processor, converting the vibration displacement data into a current signal of 4-20mA and outputting the current signal to the upper computer; the loop power supply circuit includes a loop transmitter, the signal input end of the loop transmitter is electrically connected with the processor, the power input end of the loop transmitter is electrically connected with the power supply circuit, in this embodiment, the power input end and the signal output end of the loop transmitter are electrically connected with the upper computer, and the loop transmitter can be realized by adopting a model number XTR117, but not limited to the loop transmitter. And the power supply circuit is used for providing power support for the sensor, the processor and the loop power supply circuit. In this embodiment, the power supply circuit includes a voltage converter implemented using a power chip model MAX 17530/50.
The parameter configuration method comprises the following steps:
the host drives the detection device into a parameter configuration mode.
Specifically, when the host drives the detection device to enter the parameter configuration mode, the specific steps are as follows:
the host sends a parameter configuration instruction to the loop power supply circuit;
the loop power supply circuit receives the parameter configuration instruction, and then drives the power supply circuit to supply power to the sensor and the processor; specifically, the drive power supply circuit supplies power to the sensor and the processor at a first predetermined voltage. At this time, the power supply voltage of the power supply circuit to the sensor is a first predetermined voltage; in this embodiment, the first predetermined voltage is 10V, and since the power supply voltage of most of the sensors is +24v, the power supply voltage is expanded to +15v to +30v, and the first predetermined voltage of 10V is selected to supply power to the sensors, so as to start the sensors, and the sensors enter the parameter configuration mode, so that the parameter configuration voltage and the power supply voltage can be effectively prevented from collision.
The processor sends an instruction to enter a low power consumption mode to the sensor, and the sensor enters the low power consumption mode. The low power consumption is entered for lower power consumption of the whole sensor, so that the whole current of the whole system does not exceed 2.5mA under the condition of 10V supply voltage. When the sensor enters a low power consumption mode, the power consumption can be reduced by reducing the working module, reducing the working main frequency and the like, the low power consumption of the embodiment mainly reduces the operating frequency of the sensor, and the operating frequency of the sensor is reduced from 80MHz to 168MHz, so that the power consumption is reduced to about 1/4 of the original power consumption.
The processor detects the power supply voltage of the sensor and judges whether the power supply voltage is in a parameter configuration voltage range, wherein the parameter configuration voltage range is as follows: if the voltage is 10V-15V, the processor sends a command for entering a parameter configuration mode to the sensor, the sensor receives the command for entering the parameter configuration mode and then enters the next step; if not, the processor sends a command for entering the normal working mode to the sensor, and the sensor receives the command for entering the normal working mode.
In this embodiment, if the power supply voltage from the processor to the sensor is within the normal range (+15v to +30v), the sensor is not driven into the parameter configuration mode. In addition, during normal operation of the sensor, even if the voltage is within 10V, the parameter configuration mode is not entered, so that the voltage in the use of the sensor/transmitter is prevented from being lower than the normal power supply voltage. The processor rainbow drives the sensor into the parameter configuration mode only when the sensor begins to power on and the power supply of the sensor is within the parameter configuration voltage range.
The method comprises the steps that a host sends a first data packet to a detection device, wherein the first data packet comprises a writing command byte and a target parameter byte;
the detection device receives the first data packet, and then replaces original parameters in the detection device with target parameters according to the writing command bytes and the target parameter bytes in the first data packet;
specifically, when the detection device replaces the original parameters in the detection device with the target parameters according to the write command bytes and the target parameter bytes in the first data packet, the specific steps are as follows:
the detection device replaces original parameters in the detection device with target parameters according to the writing command bytes and the target parameter bytes in the first data packet;
the detection device feeds back the first data packet to the host according to the received first data packet. By executing the step, the accuracy of data transmission can be ensured, and a user can grasp the accuracy of data received by the detection device through the host.
The host sends a second data packet to the detection device, wherein the second data packet comprises a read command byte and a parameter specification byte;
the detection device feeds back the parameter data matched with the parameter specification bytes in the detection device according to the read command bytes and the parameter specification bytes in the second data packet.
It should be noted that, the order of sending the first data packet and the second data packet to the detection device by the host is not limited, the host sends the first data packet to the detection device to modify the parameters in the detection device, and the host sends the second data packet to the detection device to receive the current parameters of the detection device, so that the user can grasp the existing precision of the detection device through the host.
The host drive detection device exits the parameter configuration mode.
Specifically, when the host driving detection device exits the parameter configuration mode, the following steps are adopted:
the host sends a third data packet to the detection device, wherein the third data packet comprises a stop command byte;
the detection device receives the third data packet and exits the parameter configuration mode according to a stop command byte in the third data packet.
In this embodiment, as shown in fig. 2, each of the first data packet, the second data packet, and the third data packet further includes a header byte and a trailer byte, where the header byte is located at a first position of the first data packet, the second data packet, or the third data packet, and the trailer byte is located at a last position of the first data packet, the second data packet, or the third data packet. The arrangement of the header byte and the trailer byte is convenient for the detection device and/or the host to confirm whether the data packet is complete.
Specifically, when the host sends a data packet to the detection device, the magnitude of the power supply voltage sent by the power supply circuit to the sensor in the detection device is changed to simulate the data level, for example, +10V output by the power supply circuit is taken as a low level, +12V output by the power supply circuit is taken as a high level, the high level or the low level lasts for a preset time T, when the power supply circuit sends 8 high levels and/or low levels to the detection device, namely one data byte is formed, and a plurality of data bytes are combined to form one data packet.
When the detecting device sends a data packet to the host, the sensor in the detecting device outputs current to the host to simulate high and low levels, for example, 2.5mA current output by the sensor in the detecting device is taken as low level, 3.3mA current output by the sensor in the detecting device is taken as high level, the high level or the low level lasts for a preset time T, and when the sensor transmits 8 high levels and/or low levels to the host, one data byte is formed; a plurality of data bytes are combined to form a data packet.
In order to distinguish data bytes, when the detection device sends a data packet to the host or the host sends a data packet to the detection device, the interval time of the data bytes in the data packet is set to be larger than 9*T so as to avoid the problem that the detection device and the host mix up the front data byte and the rear data byte.
The predetermined time T represents the hold time of each data bit in each byte, so the length of the predetermined time T determines the rate at which the parameter configuration host communicates with the sensor. The selection of the predetermined time T is related to the processing performance inside the sensor, because in the configuration mode, the sensor is in the low power mode, the performance of the internal MCU cannot be fully exerted, but t=1 ms (millisecond) can be generally guaranteed, and as the process and performance of the processor in the detection device are improved, the predetermined time T can be smaller, and a higher data transmission rate can be obtained. The predetermined time T may be increased to reduce the power consumption of the detection device. The predetermined time T in this embodiment is 1ms (millisecond).
In addition, when the host driving detection device exits the parameter configuration mode, the following steps can be adopted:
the host sends a normal operation instruction to the loop power supply circuit;
the loop power supply circuit receives a normal operation instruction and then drives the power supply circuit to normally supply power to the detection device and the processor;
the processor sends an instruction for entering the normal working mode to the detection device, and the detection device receives the instruction of the normal working mode and exits the parameter configuration mode and then enters the normal working mode.
