However, in actual operation, when a long-lasting lamp of one torch burner is turned off or turned on, the pressure in the fuel gas main pipe will change suddenly, thereby affecting the stability of fuel gas supply of the remaining long-lasting lamps in normal combustion state. SUMMARY

[0004] To achieve the above-mentioned purpose, embodiments of the present application adopt the following technical solutions: A method for intelligently adjusting fuel gas pressure of long-lasting lamps, comprising the following steps: S1: connecting a fuel gas main pipe, a plurality of long-lasting lamp fuel gas branch pipes and a plurality of long-lasting lamp bodies in communication, and arranging a pressure transmission device and a pressure regulating device at the front end of the plurality of long-lasting lamp bodies; S2: interlinking the pressure transmission device and the pressure regulating device, and setting a normal pressure value in the long-lasting lamp fuel gas branch pipe; S3: the pressure transmission device collects the fuel gas pressure in the corresponding long-lasting lamp fuel gas branch pipe in real time and generates a pressure signal; S4: constructing a pressure signal control system, transmitting the pressure signal to the pressure signal control system, converting the pressure signal to an actual pressure value in the pressure signal control system, comparing the actual pressure value with the normal pressure value, and calculating a pressure error; S5: the pressure signal control system performs proportional operation, integral operation and differential operation on the pressure error to generate a control signal; S6: transmitting the control signal to the pressure regulating device, and adjusting the valve opening degree according to the control signal in the pressure regulating device to realize dynamic adjustment of the pressure in the long-lasting lamp fuel gas branch pipe.

[0005] Furthermore, in S1, the multiple fuel gas branches of the night lamp are independent of each other, and each fuel gas branch of the night lamp is provided with an independent pressure transmission device and pressure regulating device. The pressure signal control system can realize individual control of each individual pressure transmission device and pressure regulating device, and the pressure signal control system can realize synchronous control of multiple pressure transmission devices and multiple pressure regulating devices.

[0006] Furthermore, in S4, the pressure signal control system includes a PLC control system, which has a built-in PID controller.

[0007] Furthermore, in S5, the proportional operation responds proportionally to the error; the larger the error, the stronger the control effect. The specific formula is as follows: in, This is a proportional calculation value. This is the proportionality coefficient. This is the error signal.

[0008] Furthermore, the error signal is calculated by the difference between the normal pressure value and the actual pressure value, using the following formula: in, This is the normal pressure value. This represents the actual pressure value.

[0009] Furthermore, in S5, the integration operation is performed by integrating the error to eliminate the steady-state error, and the specific formula is as follows: in, The value is the result of integration.

[0012] Furthermore, in S6, the dynamic adjustment includes three operating conditions: Operating Condition 1: When the pressure in the fuel gas branch pipe of the night lamp is within the normal range, the night lamp body burns normally, the pressure transmission device uploads the normal pressure value signal, and the pressure regulating device remains in this state without action. Operating Condition 2: When the open fuel gas branch pipe of the night lamp is closed, the pressure in the other fuel gas branch pipes of the night lamp increases, which sends a signal of increased pressure in the pipeline to the pressure transmission device. The pressure transmission device transmits this signal to the pressure signal control system, which controls the pressure regulating device to reduce the pressure in the fuel gas branch pipe of the night lamp, so that the pressure in the fuel gas branch pipe is controlled within the pressure range that allows the night lamp body to burn normally. Operating Condition 3: When the closed fuel gas branch pipe of the night lamp is opened, the pressure in the other fuel gas branch pipes of the night lamp decreases, sending a signal of reduced pressure to the pressure transmission device. The pressure transmission device transmits this signal to the pressure signal control system, which then controls the pressure regulating device to increase the pressure in the fuel gas branch pipe of the night lamp, so that the pressure in the fuel gas branch pipe is controlled within the pressure range within which the night lamp body can burn normally.

[0020] according to Figs. 1-3 As shown, the present invention provides a method for intelligently regulating the fuel gas pressure control of a continuously lit lamp, comprising the following steps: S1: Connect the fuel gas main pipe, multiple fuel gas branch pipes for the emergency lights, and multiple emergency light bodies. A pressure transmission device and a pressure regulating device are installed at the front end of the multiple emergency light bodies. The fuel gas main pipe specifications include DN50, DN40, etc. The emergency light body models are HG-20, HG-15, etc. The pressure transmission device models include MPX5700 series pressure sensors, PT2088 pressure transmitters, etc. The pressure regulating device includes AZP-16 electric regulating valves, VQ series electric ball valves, etc. S2: Link the pressure transmission device and the pressure regulation device together to set the normal pressure value in the fuel gas branch pipe of the continuous lamp.

[0021] This invention provides an intelligent method for controlling the fuel gas pressure of a nightlight. The method involves acquiring the pressure signal in the fuel gas branch pipe in real time through a pressure transmission device, and using the pressure signal control system to perform proportional, integral, and differential calculations on the pressure error to generate a precise control signal. This signal drives the pressure regulating device to dynamically adjust the valve opening, ensuring that the pressure quickly stabilizes within the normal range and effectively preventing abnormal combustion of the nightlight caused by pressure fluctuations.

[0022] To ensure strong adaptability, in the embodiments of the present invention, the multiple fuel gas branches for the continuous lamps are independent of each other. Each fuel gas branch for the continuous lamps is equipped with an independent pressure transmission device and a pressure regulating device. The pressure signal control system can realize individual control of each individual pressure transmission device and pressure regulating device, and can also realize synchronous control of multiple pressure transmission devices and multiple pressure regulating devices. The pressure signal control system can realize single-channel independent control and multi-channel synchronous control, and can flexibly adapt to the opening and closing switching conditions of different numbers of branches.

[0023] In order to achieve precise pressure control in the fuel gas branch pipe of the continuous lamp, in the embodiments of the present invention, the pressure signal control system includes a PLC control system, and the PLC control system has a built-in PID controller.

[0024] In order to respond quickly to pressure deviations, in the embodiments of the present invention, the proportional calculation responds to the error proportionally; the larger the error, the stronger the control effect. The specific formula is as follows: in, This is a proportional calculation value. This is the proportionality coefficient. This is an error signal. If the actual pressure is much lower than the normal pressure, the proportional calculation outputs a large signal to quickly open the valve and increase the pressure.

[0025] In an embodiment of the present invention, the error signal is calculated by the difference between the normal pressure value and the actual pressure value, specifically using the following formula: in, This is the normal pressure value. The actual pressure value is used to clarify the direction of error calculation and ensure the consistency of subsequent PID calculations.

[0026] In order to eliminate steady-state error, in the embodiments of the present invention, the integral operation is performed by integrating the error to eliminate steady-state error, and the specific formula is as follows: in, The value is the result of integration. This is the proportionality coefficient. For integration time, This is the integral of the error signal from 0 to time t.

[0027] By integrating the error signal over a period of time, steady-state error can be eliminated. For example, when there is a small, persistent error in the system, the integral term will gradually accumulate, increasing the control effect.

[0028] In order to respond in advance to changes in error trends, in embodiments of the present invention, the differential operation is adjusted and controlled according to the rate of change of error, as specified in the formula: in, The value is the result of the differential operation. This is the proportionality coefficient. For differential time, This represents the rate of change of error.

[0029] By using differential calculations to anticipate changes in error trends and combining this with the immediate adjustment capabilities of proportional calculations, pressure regulation achieves rapid responsiveness and long-term stability, ensuring continuous and stable combustion of the burner and enhancing the safety and reliability of the main combustion system.

[0030] In an embodiment of the present invention, the output signal of the PID controller is calculated based on the proportional, integral, and derivative operation values, as shown in the following formula: in, The output signal of the PID controller. This is the base output value when the system is in steady state.

[0031] By superimposing proportional, integral, and derivative operation values ​​and combining them with the basic output value, a control signal is formed that balances rapid response, no steady-state error, and resistance to fluctuations, ensuring precise and stable adjustment actions.

[0032] In embodiments of the present invention, dynamic adjustment includes three operating conditions: Operating Condition 1: When the pressure in the fuel gas branch pipe of the night lamp is within the normal range, the night lamp body burns normally, the pressure transmission device uploads the normal pressure value signal, and the pressure regulating device remains in this state without action. Operating Condition 2: When the fuel gas branch pipe of the open lamp is closed, the pressure of the fuel gas branch pipes of the other lamps increases, which sends a signal to the pressure transmission device that the pressure in the pipeline has increased. The pressure transmission device transmits this signal to the pressure signal control system, which controls the pressure regulating device to reduce the pressure in the fuel gas branch pipe of the lamp, so that the pressure in the fuel gas branch pipe is controlled within the pressure range that the lamp body can burn normally. Operating Condition 3: When the closed fuel gas branch pipe of the night lamp is opened, the pressure in the other fuel gas branch pipes of the night lamp decreases, which sends a signal to the pressure transmission device that the pressure in the pipeline has decreased. The pressure transmission device transmits this signal to the pressure signal control system, which controls the pressure regulating device to increase the pressure in the fuel gas branch pipe of the night lamp, so that the pressure in the fuel gas branch pipe is controlled within the pressure range that the night lamp body can burn normally.

[0033] A smart control system for regulating fuel gas pressure in a continuous light, comprising: Pressure collection and transmission system: used to collect the pressure in the fuel gas branch pipes of multiple lamps and generate pressure signals, and transmit the pressure signals; Pressure signal control system: Receives pressure signal, converts pressure signal into actual pressure value, compares actual pressure value with normal pressure value, calculates pressure error, performs proportional, integral and differential operations on pressure error, and generates control signal; Pressure regulation system: Receives control signals and adjusts the valve opening to achieve dynamic adjustment of the pressure in the fuel gas branch pipe of the night light.

[0034] Example 1: This embodiment includes three independent fuel gas branch pipes for the continuous light, the fuel gas type is liquefied petroleum gas, the main body of the continuous light is model HG-20, and the combustion pressure is required to be stable at 0.2MPa±0.02MPa; S1: Connect the DN50 fuel gas main pipe to the three DN15 fuel gas branch pipes for the night lamps via a diversion valve. Each branch pipe is connected to one HG-20 night lamp body. On the branch pipe at the front end of each night lamp body, install an MPX5700 series pressure sensor and a ZAZP-16 electric regulating valve respectively. The pressure sensor and the electric regulating valve communicate with the pressure signal control system via an RS485 bus. S2: The upper computer software of the PLC control system completes the linkage calibration of the pressure sensor and the electric regulating valve to ensure that the signal transmission delay is ≤50ms; based on the combustion test data of the lamp, the normal pressure value SP=0.2MPa is set, and the normal pressure range is 0.18MPa-0.22MPa; S3: The pressure sensor collects the pressure inside the branch pipe in real time at a sampling frequency of 15Hz, converts the pressure physical quantity into a standard voltage signal of 0-10V, and continuously uploads it to the pressure signal control system. S4: The pressure signal control system uses a Mitsubishi FX3U series PLC with a built-in PID control module; after receiving the voltage signal, the system obtains the actual pressure value PV through analog-to-digital conversion, according to the formula... Calculate the pressure error: when PV = 0.23 MPa, e(t) = 0.2 - 0.23 = -0.03 MPa; when PV = 0.17 MPa, ; S5: PID controller parameter setting: proportional coefficient Integral time Differential time The system's steady-state basic output value ; Proportional calculation: When e(t) = 0.03 MPa, ; Integration: Integrate the error signal over the first 10 seconds. If the error remains at 0.01 MPa, then I = 4.5 × × =4.5× ×0.1=0.05625; Differential calculation: When the error changes from 0.02 MPa to 0.03 MPa within 2 seconds, the rate of change of the error... = =0.005MPa / s, then D=4.5×1.5×0.005=0.03375; Output signal: =0.135+0.05625+0.03375+5=5.225V; S6: The electric regulating valve receives a 5.225V control signal and adjusts the valve opening from 50% to 52.25%, increasing the fuel gas flow and causing the branch pipe pressure to rise from 0.17MPa to about 0.2MPa. When one branch pipe is closed, the pressure in the other two branch pipes instantly rises to 0.25 MPa. After the pressure sensor transmits the signal, the system outputs a 4.7V control signal through the PID controller, and the electric regulating valve closes to 47%. The pressure recovers to 0.21 MPa within 1.2 seconds. When the closed branch pipe is reopened, the pressure in the other two branch pipes drops to 0.16 MPa. The system outputs a 5.3V control signal, and the valve opening is adjusted to 53%. The pressure recovers to 0.19 MPa within 1.5 seconds.

[0035] Example 2: This embodiment includes 10 independent fuel gas branch pipes for the continuous lamp; S1: Ten-way continuous light fuel gas branch pipes are all DN20 specification. Each branch pipe is equipped with an independent PT2088 pressure transmitter and VQ series electric ball valve. All equipment is connected to the pressure signal control system via industrial Ethernet. S2: Set the normal pressure value SP=0.4MPa, and the normal range is 0.37MPa-0.43MPa; through the synchronous control function of the PLC control system, complete the linkage debugging of 10 pressure transmission devices and regulating devices to ensure that the pressure deviation of each channel is ≤±0.01MPa during synchronous regulation. S3: The pressure transmitter acquires pressure signals at a 20Hz acquisition frequency and converts them into 4-20mA current signals for uploading, where 4mA corresponds to 0MPa and 20mA corresponds to 1MPa. S4: The pressure signal control system uses a Siemens S7-1500 series PLC, equipped with an ET200SP distributed I / O module and a built-in advanced PID controller; the system converts 4-20mA signals into actual pressure values, for example, 12mA corresponds to a pressure value PV= If ×1=0.5MPa, then e(t)=0.4−0.5=−0.1MPa; S5: PID controller parameter optimization settings: =6.0, =12s, =3s, =12mA, corresponding to a valve opening of 50%; When all 10 branch pipes are running simultaneously, if the overall pressure is low to 0.36MPa, the average error e(t) is calculated to be 0.04MPa. After calculation by the PID controller, a 13.8mA control signal is output, and the opening of all 10 electric ball valves is synchronously increased to 59%. Within 2.5s, the overall pressure stabilizes at 0.4MPa. When the pressure of the fifth branch pipe drops to 0.32MPa due to blockage, while the pressure of the other nine branches is normal, the system only adjusts the fifth branch independently, outputting a 14.2mA control signal. The valve opening of this branch is adjusted to 61%, and the pressure recovers to 0.39MPa within 2.0s. The other branches maintain their original openings. S6: When four branch pipes are shut down simultaneously, the pressure in the remaining six branch pipes rises sharply to 0.52MPa. The system responds quickly, outputting a 9.5mA control signal, reducing the valve opening to 47.5%, and the pressure drops to 0.42MPa within 2.8 seconds. After 72 hours of continuous operation, the pressure fluctuation range of all 10 branch pipes is controlled within 0.38MPa-0.42MPa, with no instances of the lights going out or unstable combustion.
