[0023] The present application provides a calibration device for a combustible gas controller, such as Figure 1As shown, the calibration device of the combustible gas controller includes a master controller 100 and multiple slave controllers 200, each interactive interface of the multiple slave controllers 200 is connected to each interactive interface of the corresponding combustible gas controller 300, the slave input interfaces of the multiple slave controllers 200 are connected to the master output interface of the master controller 100, and the slave communication interfaces of the multiple slave controllers 200 are connected to the master communication interfaces of the corresponding master controller 100; The main controller 100 is configured to: obtain a first input regarding a target combustible gas controller; determine program configuration information of the target combustible gas controller based on the first input; and when the program configuration information indicates that the target combustible gas controller is in a program pending update state, update identification information of the target combustible gas controller to a set detection process, and determine a target detection node for performing device detection on the target combustible gas controller; The master controller 100 is further configured to: instruct the target slave controller to execute a detection instruction for detecting the target combustible gas controller at the target detection node; 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 main 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 the main controller 100 to exchange data with the server 50 via the 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 provide power to the main controller 100 through the power grid 60. The main controller 100 can be configured with a first voltage conversion module 17, which can include an AD / DC conversion module and a DC / DC conversion module. The AD / DC conversion module can convert 220V AC power into 24V DC power, and the DC / DC conversion module can convert 24V DC power into 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, and the main controller 100 can be electrically connected to the main display screen 40 via the serial port screen interface 14. The main controller 100 can be configured with a main current detection module 13, which 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, so that the main control chip 10 controls the main controller 100 to stop running when it determines through the main current detection module 13 that the internal current of the main controller 100 exceeds the current threshold.

[0026] In this embodiment, the master controller 100 transmits DC power to the slave input modules of each slave controller 200 via the master 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 needs of the slave control chip 20, thereby meeting the power requirements of the slave controller 200. The second voltage conversion module 31 is generally a conventional DC / DC converter 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 40, and then obtains the controller's factory serial number set from the server 50 based on the set batch production quantity. The main controller 100 then sends a program version number comparison request to the server 50 for the target combustible gas controller 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 pending program update state, the identification information of the target combustible gas controller is updated to the set detection process, and the target detection node for device detection of the target combustible gas controller is determined. The identification information here can be a character string representing the target combustible gas controller.

[0028] In this embodiment, the configured main controller 100 and the slave controller 200 cooperate with each other, and the main controller 100 sets the detection node for the combustible gas controller 300 to detect. Moreover, when the detection process reaches a detection node, the slave controller 200 corresponding to the detection node detects the corresponding combustible gas controller 300, thereby effectively improving the calibration efficiency of the calibration device of the combustible gas controller.

[0029] In some embodiments, the master controller 100 is further configured to: when the program configuration information indicates that the target combustible gas controller is in a program waiting to be updated state, obtain the program firmware of the target combustible gas controller; send the program firmware to the target slave controller so that the target slave controller stores the program firmware; Among them, the target slave controller is set to: respond to the access signal of the target combustible gas controller, update the target combustible gas controller through the program firmware; when obtaining the update completion information of the target combustible gas controller, feedback to the main controller 100 that the target combustible gas controller is in the detection ready state.

[0030] In this embodiment, when the program configuration information indicates that the target combustible gas controller is in the pending program update state, the master controller 100 automatically obtains the latest program firmware for the target combustible gas controller from the server 50. After successfully verifying the obtained program firmware, the master controller 100 sends the updated program firmware to all slave controllers 200 via the RS485 broadcast protocol. After the slave controllers 200 obtain and successfully verify the program firmware, they store it in the FLASH15 memory chip on their respective slave controllers 200. The combustible gas controller calibration device enters a standby state, awaiting access to the combustible gas controller 300. The combustible gas controller 300 connects to the slave controller 200 via a customized multi-plug terminal. The slave controller 200 reads the combustible gas controller 300's version information via the second host interface and the second slave interface. If the combustible gas controller 300 fails to respond after multiple inquiries or the control software version is too low, the slave controller 200 automatically initiates the program download function via the program download module 26 to flash the latest program to the combustible gas controller 300. After the combustible gas controller 300 program is successfully upgraded, it enters a detection-ready state. This detection-ready state is displayed on the slave display screen 27 of the slave controller 200. Furthermore, information indicating that the combustible gas controller 300 is in the detection-ready state is sent to the corresponding master communication module 11 of the master controller 100 via the slave communication module of the slave controller 200. The master controller 100 displays the detection-ready state information on the master 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 slave controller to execute a detection instruction for detecting the target combustible gas controller, the master controller 100 is further configured to: determine a current state of the target combustible gas controller; Instructing the target slave controller to execute the detection instruction of the target combustible gas controller at the target detection node, including: obtaining the current state of the target combustible gas controller as the detection ready state through the target slave controller; when the detection process reaches the target detection node, instructing the target slave controller to execute the detection instruction of the target combustible gas controller.

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

[0033] In some embodiments, the various interactive interfaces of the slave controller 200 include a first host interface and a first slave interface of the slave controller 200; the slave 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; Among them, the slave control chip 20 of the target slave controller is configured to: receive a first detection instruction for detecting 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 through the slave display screen 27 when obtaining the feedback communication configuration information of the target combustible gas controller through the first slave interface of the target slave controller.

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

[0035] In this embodiment, the slave control chip transmits a communication test protocol to the target combustible gas controller via the first host interface, and the second slave interface receives the handshake protocol sent by the target combustible gas controller. After communicating a set number of packets, the slave control chip 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 test pass on the slave display 27. The slave control chip also transmits the packet loss rate and test status to the master controller 100, thereby verifying the communication link with the target combustible gas controller.

[0036] In some embodiments, the slave controller 200 further includes a current conversion module 21, the slave control 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; Among them, the slave control chip 20 of the target slave controller is configured to: receive a second detection instruction of the current acquisition interface of the target combustible gas controller; control the current conversion module 21 to output a current signal; when obtaining the signal sampling value of the target combustible gas controller through the first host interface of the target slave controller, determine the error value of the signal sampling value; when the error value is less than the set threshold, 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.

[0037] In this embodiment, the slave control chip 20 outputs a PWM signal, which is converted into a standard 4-20mA current signal by the current conversion module 21, thereby generating a standard 4-20mA current signal. The slave control chip 20 reads the 4-20mA signal sampling value output by the target combustible gas controller via the first host interface. If the error value of the signal sampling value is less than a set threshold, the slave 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 slave control chip 20 reads the calibration data of the target combustible gas controller and displays the entire process and results on the slave display 27. The calibration data is also sent to the master controller 100 to achieve current calibration of the target combustible gas controller.

[0038] In some embodiments, the slave controller 200 further includes a switch value detection module 22, the switch value detection module 22 is electrically connected to the slave control chip 20, and the switch value detection interface of the switch value detection module 22 is electrically connected to the relay interface of the target combustible gas controller; Among them, the slave control chip 20 of the target slave controller is configured to: receive the third detection instruction of the relay interface of the target combustible gas controller; send the relay detection protocol to the second slave interface of the target combustible gas controller through the first host interface of the target slave controller; obtain the switch signal of the target combustible gas controller through the switch quantity detection module 22, and determine the switch detection information according to the switch signal; and display the switch detection information through the slave display screen 27.

[0039] In this embodiment, the slave control chip transmits a relay detection protocol via the first host interface to the second slave interface of the target combustible gas controller, thereby controlling the closing and opening of the target combustible gas controller's relay. The slave control chip 20 then obtains the target combustible gas controller's relay closing and opening signals via the switch detection module 22. If the switch signal indicates that the transmitted protocol and the detection status are consistent, the switch detection information can be indicated as indicating that the target combustible gas controller's relay interface has passed the test. The slave control chip 20 displays the entire process and results on the slave display screen 27 and simultaneously transmits the switch detection information to the master controller 100 to calibrate the relay.

[0040] In some embodiments, the slave controller 200 further includes a load adjustment module 24 and a current detection module 25, the load adjustment module 24 and the current detection module 25 are electrically connected to the slave control chip 20, the power detection interface of the load adjustment 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; Among them, the slave control chip 20 of the target slave controller is configured to: receive the fourth detection instruction for detecting the DC power supply 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 according to 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 regulation module 24 via the field-effect transistor in the load regulation 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 the first output interface of the slave control chip 20 via the AC current detection module 25, thereby estimating the load capacity and conversion efficiency of the switching power supply within the target combustible gas controller in either the light load mode or the heavy load mode. The slave control chip 20 displays the detection process and results on the slave display screen 27 and simultaneously transmits the detection results to the master controller 100, thereby detecting the load capacity and conversion efficiency of the switching power supply within the target combustible gas controller.

[0042] In some embodiments, the slave controller 200 further includes a light intensity detection module 28 , which is electrically connected to the slave control chip 20 ; Among them, the slave control chip 20 of the target slave controller is configured to: receive the fifth detection instruction for detecting the light detection of the target combustible gas controller; send a 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 when obtaining the light brightness information through the light intensity detection module 28, determine whether the light of the target combustible gas controller is abnormal through the light brightness information.

[0043] In this embodiment, the slave control chip 20 sends a light test protocol to the combustible gas controller 300 via 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 lights of the combustible gas controller 300 during this process via the light intensity detection module 28. If the changes in the brightness of the lights of the combustible gas controller 300 are synchronized with the frequency of the lights on and off, the combustible gas controller 300 is determined to have passed the test. The slave control chip 20 displays the light test process and results on the slave display 27 and simultaneously sends the test results to the master controller 100, thereby completing the light test of the combustible gas controller 300.

[0044] In some embodiments, the slave controller 200 further includes a sound intensity detection module 29 , which is electrically connected to the slave control chip 20 ; Among them, the slave control chip 20 of the target slave controller is configured to: receive the sixth detection instruction 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 when the sound intensity information is obtained through the sound intensity detection module 29, determine whether the buzzer of the target combustible gas controller is abnormal through the sound intensity information.

[0045] In this embodiment, the main controller 100 submits a sound detection request to the server 50. The server 50 allows only one auxiliary device in the same area to enter the buzzer phase to prevent interference between different auxiliary devices, which could result in erroneous detection results. After the auxiliary device obtains sound test permission, the main controller 100 assigns permission to one or more slave control chips 20 one by one. The slave control chip 20 then sends the buzzer test protocol to the combustible gas controller 300, which then turns the buzzer on and off according to the buzzer test protocol. The slave control chip 20 samples the current buzzer sound changes through the sound intensity detection module 29. If the sampled sound changes are consistent with the frequency of the buzzer test protocol, then the combustible gas controller 300 determines that the buzzer test has passed. The slave control chip 20 displays the buzzer test process and results on the slave display 27 and sends the test results to the main controller 100. The main controller 100 receives the detection result and ends the buzzer test protocol, and then starts the next round of detection of the buzzer of the combustible gas controller 300 until the buzzers of all combustible gas controllers 300 are fully detected to achieve the detection of the buzzers of the combustible gas controller 300.
