To improve production quality, workers need to continuously adjust the parameters of the gas burners, including flame length, flame redness, flame whiteness, and flame drift. Workers must observe the flame status on-site and make corresponding controls. Currently, burner adjustment requires two workers: one observes the combustion process in front of the burner, while the other operates the system at the control cabinet. The control cabinet includes a PLC controller and buttons, which control components such as the gas valve, primary air damper, secondary air damper, and igniter.

[0003] The above operation requires close coordination between two people, making it inconvenient to perform. Summary of the Invention

Detailed Implementation

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0027] Example 1

[0028] like Figures 1-4 As shown, a remote control device for adjusting a burner includes a PLC controller 1 and a burner. The burner is equipped with a gas valve 2, a primary air damper 3, a secondary air damper 4, and an igniter. The output terminal of the PLC controller 1 is connected to the gas valve 2, the primary air damper 3, the secondary air damper 4, and the igniter. The PLC controller 1 is characterized by having a first wireless communication module 6. The PLC controller 1 is connected to a remote controller via the first wireless communication module 6. The remote controller includes a housing 7, a main control unit 8, a button module 9, a display module 10, and a second wireless communication module 11.

[0029] The main control unit 8 is communicatively connected to the display module 10, the output terminal of the button module 9 is connected to the input terminal of the main control unit 8, and the main control unit 8 is communicatively connected to the second wireless communication module 11.

[0030] The display module 10 is provided in the middle of the outer casing 7, and button holes are provided on both sides of the outer casing 7 corresponding to the button module 9. The button module 9 includes multiple buttons, which are disposed in the button holes.

[0031] The main control unit 8 includes an MCU chip, and the display module 10 includes an LED display screen. The MCU chip and the LED display screen are connected via a UART serial port.

[0032] The button module 9 includes three rotary switches and three push-button switches. The output terminals of the rotary switches and the push-button switches are all connected to the input pins of the MCU chip.

[0033] The first wireless communication module 6 and the second wireless communication module 11 include one or more combinations of Bluetooth module, WiFi module and RFID module;

[0034] The second wireless communication module 11 is connected to the MCU chip via UART serial port communication.

[0035] The outer shell 7 is a waist-shaped perforated structure made of plastic material, including an upper shell and a lower shell. The upper shell and the lower shell are fixed by bolts, and the button hole is opened on the upper shell.

[0036] A clip 12 is provided at the bottom of the lower housing, and one side of the clip 12 is fixed to the lower housing.

[0037] A relay 13 is provided between the PLC controller 1 and the igniter. The coil of the relay 13 is connected to the output terminal of the PLC controller 1, and the normally open contact of the relay 13 is connected to the igniter.

[0038] Both the primary air damper 3 and the secondary air damper 4 are equipped with hydraulic cylinders, and the hydraulic cylinders are connected to solenoid valves. The coils of the solenoid valves are electrically connected to the output terminals of the PLC controller 1.

[0039] In this embodiment, a boost circuit is provided, which uses a KF2185 boost chip. One end of the boost circuit is connected to a button battery, and the other end is connected to the main control unit 8, the button module 9, the display module 10, and the second wireless communication module 11. The MCU chip is an STM32 microcontroller, and the second wireless communication module 11 is an RFRD module, specifically an RFRD transmitter chip (RC522), which is equipped with an antenna. The corresponding first wireless communication module 6 is an RFRD receiver chip. The three rotary switches include K1, K2, and K3, and the three button switches include K4, K5, and K6. K1 adjusts the opening of the gas valve 2, K2 adjusts the opening of the primary air damper 3, K3 adjusts the opening of the primary air damper 4, K4 is for igniter on / off; K5 is for communication pairing, and K6 is for remote control power-on start.

[0040] During operation, the operator stands in front of the burner to observe the flame. If the flame is long, it indicates that the gas valve 2 is too open. Rotating K1 changes the resistance of K1, which in turn changes the voltage output of K1. The main control unit 8 transmits the output signal to the PLC controller 1 through the second wireless communication module 11 and the first wireless communication module 6. The PLC controller 1 controls the gas valve 2 to close, thus regulating the burner. If the flame is red, it indicates that the primary air damper 3 is not open enough, or that the secondary air damper 4 needs to be opened. During operation, the operator rotates K2 or K3. According to the above working principle, the main control unit 8 transmits the output signal to the PLC controller 1 through the second wireless communication module 11 and the first wireless communication module 6. The PLC controller 1 controls the solenoid valve to switch direction and energize the solenoid valve, thereby controlling the piston movement of the hydraulic cylinder to open, close, and control the degree of opening of the primary air damper 3 or the secondary air damper 4.

[0041] If the flame is short, it indicates that the gas valve 2 is not open enough and the primary air damper 3 is not open enough. Rotate K1 and K2 according to the above control process to adjust the burner parameters.

[0042] A white flame indicates excess air, requiring a reduction in the opening of the primary air damper 3 and the secondary air damper 4. Follow the control procedure described above to rotate K2 or K3 to adjust the burner parameters.

[0043] During ignition, the operator presses K4. The main control unit 8 transmits the output signal to the PLC controller 1 via the second wireless communication module 11 and the first wireless communication module 6. The PLC controller 1 energizes the coil of relay 13, and the igniter is energized through the normally open contact of the relay, thus igniting the igniter. Releasing K4 de-energizes the coil of relay 13, causing the normally open contact of the relay connected to the igniter to open, and the igniter stops working.

[0044] The embodiments described above are merely preferred embodiments of this utility model and are not intended to limit the scope of implementation of this utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the patent claims of this utility model should be included within the scope of the patent application of this utility model.
