[0023] This application provides a calibration device for a combustible gas controller, such as... Figure 1As shown, the calibration device for the combustible gas controller includes a main controller 100 and multiple slave controllers 200. Each interaction interface of the multiple slave controllers 200 is connected to each interaction interface of the corresponding combustible gas controller 300. The slave input interfaces of the multiple slave controllers 200 are connected to the main output interface of the main controller 100. The slave communication interfaces of the multiple slave controllers 200 are connected to the main communication interface of the corresponding main controller 100. The main controller 100 is configured to: acquire a first input about the target combustible gas controller; determine the program configuration information of the target combustible gas controller based on the first input; when the program configuration information reflects that the target combustible gas controller is in a program pending update state, update the identification information of the target combustible gas controller to the set detection process, and determine the target detection node for equipment detection of the target combustible gas controller. The main controller 100 is further configured to instruct the target slave controller at the target detection node to execute a detection command to detect the target combustible gas controller; wherein the combustible gas controller 300 includes the target combustible gas controller, and the slave controller 200 includes the target slave controller.

[0024] In this embodiment, the slave controller 200 may include a slave control chip 20, a second signal conversion module 30, and a slave communication module 32. The slave control chip 20 can convert the TTL signal into an RS485 signal through the second signal conversion module 30 and send it to the master controller 100 through the slave communication module 32.

[0025] In this embodiment, the first input can be output by the server 50, and the main controller 100 can be configured with a WIFI module 16 to enable data interaction between the main controller 100 and the server 50 via a WIFI network. The main controller 100 can be configured with a main input module 18, which can be connected to the power grid 60 to supply power to the main controller 100. The main controller 100 can be configured with a first voltage conversion module 17, which may include an AD / DC conversion module and a DC / DC conversion module. The AD / DC conversion module can convert 220V AC power to 24V DC power, and the DC / DC conversion module can convert 24V DC power to 5V DC power to provide power to different modules of the main controller 100. The main controller 100 can be configured with a serial port screen interface 14, through which the main controller 100 can be electrically connected to the main display screen 40. The main controller 100 can be configured with a main current detection module 13. The main current detection module 13 can detect the internal current of the main controller 100 and feed it back to the main control chip 10 of the main controller 100. When the main control chip 10 determines through the main current detection module 13 that the internal current of the main controller 100 exceeds the current threshold, it controls the main controller 100 to stop running.

[0026] In this embodiment, the main controller 100 transmits DC power to the slave input modules of each slave controller 200 through the main output module 12. Furthermore, the second voltage conversion module 31 of the slave controller 200 converts the DC power input from the slave input module 33 into DC power that meets the requirements of the slave control chip 20, thereby satisfying the power needs of the slave controller 200. The second voltage conversion module 31 is typically a conventional DC / DC conversion circuit.

[0027] In this embodiment, the main controller 100 obtains the system time from the server 50, sets the batch production quantity through the main display screen 40, and obtains the controller factory serial number set from the server 50 based on the set batch production quantity. The main controller 100 sends a target combustible gas controller program version number comparison to the server 50 to obtain the program configuration information of the target combustible gas controller. If the program configuration information indicates that the target combustible gas controller is in a program update pending state, the identification information of the target combustible gas controller is updated to the set detection process, and the target detection node for equipment detection of the target combustible gas controller is determined. The identification information here can be a string representing the target combustible gas controller.

[0028] In this embodiment, the master controller 100 and slave controller 200 cooperate with each other. The master controller 100 sets the detection nodes detected by the combustible gas controller 300. When the detection process reaches a detection node, the slave controller 200 corresponding to the detection node detects the corresponding combustible gas controller 300, which effectively improves the calibration efficiency of the calibration device for the combustible gas controller.

[0029] In some embodiments, the main controller 100 is further configured to: obtain program firmware for the target combustible gas controller when the program configuration information reflects that the target combustible gas controller is in a program pending update state; and send the program firmware to the target slave controller so that the target slave controller stores the program firmware. The target controller is configured to: update the target combustible gas controller via firmware in response to the access signal of the target combustible gas controller; and, upon receiving the update completion information of the target combustible gas controller, report to the main controller 100 that the target combustible gas controller is in a detection-ready state.

[0030] In this embodiment, when the program configuration information indicates that the target combustible gas controller is in a program update pending state, the main controller 100 automatically obtains the latest program firmware of the target combustible gas controller from the server 50. After the main controller 100 obtains and successfully verifies the program firmware, it sends the program firmware to all slave controllers 200 via the RS485 broadcast protocol. After the slave controller 200 obtains and successfully verifies the program firmware, it stores the program firmware in the FLASH15 storage chip on the slave controller 200. The calibration device of the combustible gas controller is in standby mode, waiting for the combustible gas controller 300 to connect. The combustible gas controller 300 is connected to the slave controller 200 through a customized multi-plug terminal. The slave controller 200 reads the version information of the combustible gas controller 300 through the second host interface and the second slave interface. If the combustible gas controller 300 does not respond to any data after multiple queries or the control software version is too low, the slave controller 200 automatically starts the program download function through the program download module 26 to burn the latest program to the combustible gas controller 300. After the combustible gas controller 300 program is successfully upgraded, it enters the detection-ready state. This detection-ready state is displayed on the slave display screen 27 of the slave controller 200, and the slave communication module of the slave controller 200 sends the information that the combustible gas controller 300 is in the detection-ready state to the corresponding master communication module 11 of the master controller 100. The master controller 100 displays the information that the combustible gas controller 300 is in the detection-ready state on the main display screen 40, and updates the identification information of the combustible gas controller 300 to the set detection process, thereby initializing the calibration device of the combustible gas controller and updating the program of the combustible gas controller 300.

[0031] In some embodiments, before the target detection node instructs the target to execute a detection command from the controller to detect the target combustible gas controller, the main controller 100 is further configured to: determine the current state of the target combustible gas controller; The target detection node instructs the target slave controller to execute the detection command for detecting the target combustible gas controller, including: obtaining the current state of the target combustible gas controller as a detection ready state through the target slave controller; and instructing the target slave controller to execute the detection command for detecting the target combustible gas controller when the detection process reaches the target detection node.

[0032] In this embodiment, the combustible gas controller 300 is tested after the program of the combustible gas controller 300 is updated, which effectively improves the accuracy of the combustible gas controller 300 test.

[0033] In some embodiments, each interaction interface of the controller 200 includes a first host interface and a first slave interface of the controller 200; the controller 200 includes a first signal conversion module 23, a slave control chip 20 and a slave display screen 27, the first host interface and the first slave interface are connected to the first signal conversion module 23, and the slave control chip 20 is electrically connected to the first signal conversion module 23 and the slave display screen 27 respectively. The slave control chip 20 of the target slave controller is configured to: receive a first detection command to detect the communication link of the target combustible gas controller; send a communication test protocol to the second slave interface of the target combustible gas controller through the first host interface of the target slave controller; and display the communication configuration information on the display screen 27 when the target combustible gas controller provides feedback on the communication configuration information through the first slave interface of the target slave controller.

[0034] In this embodiment, the first signal conversion module 23 can convert the RS485 signal into a TTL signal and output the TTL signal to the slave control chip.

[0035] In this embodiment, the slave control chip sends a communication test protocol to the target combustible gas controller through the first host interface, and the second slave interface receives the handshake protocol sent by the target combustible gas controller. After the slave control chip communicates a set number of packets, it calculates the packet loss rate. If the packet loss rate is less than 1%, the slave control chip 20 displays the packet loss rate and RS485 communication detection passed on the slave display screen 27, and simultaneously sends the packet loss rate and detection status to the master controller 100 to realize the detection of the communication link of the target combustible gas controller.

[0036] In some embodiments, the controller 200 further includes a current conversion module 21, the controller chip 20 is electrically connected to the current conversion module 21, and the current output interface of the current conversion module 21 is electrically connected to the current acquisition interface of the target combustible gas controller. The slave control chip 20 of the target slave controller is configured to: receive a second detection command from the current acquisition interface of the target combustible gas controller; control the current conversion module 21 to output a current signal; determine the error value of the signal sampling value when the signal sampling value of the target combustible gas controller is obtained through the first host interface of the target slave controller; and send a current calibration protocol to the second slave interface of the target combustible gas controller through the first host interface of the target slave controller when the error value is less than a set threshold.

[0037] In this embodiment, a PWM signal is output from the control chip 20. The PWM signal is converted into a standard 4-20mA current signal by the current conversion module 21, thereby generating a standard 4-20mA current signal. The control chip 20 reads the sampled value of the 4-20mA signal output by the target combustible gas controller through the first host interface. If the error value of the signal sampled value is less than a set threshold, the control chip 20 sends a 4-20mA current calibration protocol to the slave controller 200. The target combustible gas controller saves the 4-20mA signal current calibration protocol to its internal memory. The control chip 20 reads the calibration data of the target combustible gas controller and displays the entire process and results on the slave display screen 27. At the same time, it sends the calibration data to the master controller 100 to realize the current calibration of the target combustible gas controller.

[0038] In some embodiments, the controller 200 further includes a switch quantity detection module 22, which is electrically connected to the control chip 20, and the switch quantity detection interface of the switch quantity detection module 22 is electrically connected to the relay interface of the target combustible gas controller. The slave control chip 20 of the target slave controller is configured to: receive a third detection command from the relay interface of the target combustible gas controller; send a relay detection protocol to the second slave interface of the target combustible gas controller through the first master interface of the target slave controller; obtain the switch signal of the target combustible gas controller through the switch quantity detection module 22, determine the switch detection information based on the switch signal; and display the switch detection information on the display screen 27.

[0039] In this embodiment, the control chip 20 sends a relay detection protocol to the second slave interface of the target combustible gas controller through the first host interface, thereby controlling the closing and opening of the relay of the target combustible gas controller. The control chip 20 then obtains the closing and opening signals of the relay of the target combustible gas controller through the switch quantity detection module 22. If the switch signal indicates that the sending protocol and the detection status are consistent, the switch detection information can indicate that the relay interface of the target combustible gas controller has passed the detection. The control chip 20 displays the entire process and results on the slave display screen 27, and at the same time sends the switch detection information to the master controller 100 to achieve relay calibration.

[0040] In some embodiments, the controller 200 further includes a load regulation module 24 and a current detection module 25. The load regulation module 24 and the current detection module 25 are electrically connected to the controller chip 20. The power detection interface of the load regulation module 24 is electrically connected to the second output interface of the target combustible gas controller, and the first output interface of the current detection module 25 is electrically connected to the input interface of the target combustible gas controller. The slave control chip 20 of the target slave controller is configured to: receive the fourth detection command for detecting the DC power output of the target combustible gas controller; control the load module of the load adjustment module 24 to configure the target resistance value; and determine the load capacity and conversion efficiency of the target combustible gas controller based on the load mode set by the target resistance value and the current passing through the current detection module 25.

[0041] In this embodiment, the slave control chip 20 can adjust the resistance value of the load resistor in the load adjustment module 24 through the field-effect transistor in the load adjustment module 24 to switch the load mode to either a light load mode or a heavy load mode. The slave control chip 20 detects the current flowing through its first output interface via the AC current detection module 25, thereby estimating the load-carrying capacity and conversion efficiency of the switching power supply within the target combustible gas controller under either light load or heavy load mode. The slave control chip 20 displays the detection process and results on the slave display screen 27 and simultaneously sends the detection results to the main controller 100 to achieve the detection of the load-carrying capacity and conversion efficiency of the switching power supply within the target combustible gas controller.

[0042] In some embodiments, the controller 200 further includes a light intensity detection module 28, which is electrically connected to the controller chip 20. The slave control chip 20 of the target slave controller is configured to: receive the fifth detection command for detecting the light of the target combustible gas controller; send the light test protocol to the second slave interface of the target combustible gas controller through the first host interface of the target slave controller; and determine whether the light of the target combustible gas controller is abnormal when the light intensity detection module 28 obtains the light brightness information.

[0043] In this embodiment, the slave control chip 20 sends a lighting test protocol to the combustible gas controller 300 through the first host interface. The combustible gas controller 300 turns all indicator lights on and off one by one. The slave control chip 20 detects the changes in the lighting during the switching process of the combustible gas controller 300 through the light intensity detection module 28. If the change in the brightness of the lights in the combustible gas controller 300 is consistent with the switching frequency of the lights, then the combustible gas controller 300 is deemed to have passed the test. The slave control chip 20 displays the lighting test process and results on the slave display screen 27, and simultaneously sends the test results to the master controller 100 to realize the testing of the lights configured on the combustible gas controller 300.

[0044] In some embodiments, the controller 200 further includes a sound intensity detection module 29, which is electrically connected to the controller chip 20. The slave control chip 20 of the target slave controller is configured to: receive the sixth detection command for detecting the sound intensity of the target combustible gas controller; send a buzzer test protocol to the second slave interface of the target combustible gas controller through the first host interface of the target slave controller; and determine whether the buzzer of the target combustible gas controller is abnormal when the sound intensity information is obtained through the sound intensity detection module 29.

[0045] In this embodiment, the main controller 100 sends a sound detection request to the server 50. The server 50 ensures that only one auxiliary device can enter the buzzer circuit within the same area to prevent interference between different auxiliary devices and thus avoid erroneous detection results. After the auxiliary device obtains sound testing permission, the main controller 100 assigns the permission to one or more slave control chips 20. The slave control chip 20 then sends the buzzer testing protocol to the combustible gas controller 300, which switches the buzzer on and off according to the protocol. The slave control chip 20 samples the current buzzer sound change through the sound intensity detection module 29. If the sampled sound change is consistent with the frequency synchronization of the buzzer testing protocol, the combustible gas controller 300 determines that the buzzer detection has passed. The slave control chip 20 displays the buzzer detection process and results on the slave display screen 27 and simultaneously sends the detection results to the main controller 100. The main controller 100 receives the test result and terminates the buzzer test protocol, then starts the next round of buzzer testing for the combustible gas controllers 300, until all buzzers of the combustible gas controllers 300 have been tested, thus realizing the testing of the buzzers of the combustible gas controllers 300.
