[0020] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.
[0021] like Figure 2 , 3 As shown, this utility model proposes an explosion-proof lamp capable of detecting environmental parameters, including an explosion-proof lamp body 11, an LED lamp 12, a heat sink 13, a control board housing 14, a mounting base 15, a support frame 16, and a status indicator unit 17. The LED lamp 12 is provided at the bottom of the explosion-proof lamp body 11, the status indicator unit 17 is provided on the side of the explosion-proof lamp body 11, the heat sink 13 is provided at the top of the explosion-proof lamp body 11, the heat sink 13 is connected to one side of the control board housing 14, the support frame 16 is installed on the other side of the control board housing 14, and the mounting base 15 is installed on the support frame 16.
[0022] like Figure 3 As shown, a control board is installed inside the control board housing 14. The control board includes an explosion-proof lamp controller 18 and a Bluetooth module 19, a combustible gas sensor 110, a dust sensor 111, a temperature sensor 112, a voltage sampling unit 113, a current sampling unit 114, and a PWM control module 116 that are electrically connected to the explosion-proof lamp controller 18. The PWM control module 116 is electrically connected to the LED light 12. The explosion-proof lamp controller 18 is also electrically connected to the status indicator unit 17.
[0023] Among them, Bluetooth module 19 is wirelessly connected to Bluetooth router 2, Bluetooth router 2 is wirelessly connected to main station 4 through 4G / 5G network 3, and main station 4 is a network server.
[0024] The explosion-proof light controller 18 uses an STM32 series microcontroller. The STM32 series is a 32-bit microcontroller based on the ARM Cortex-M core, manufactured by STMicroelectronics. This series of microcontrollers is widely used in the industry due to its high performance, strong real-time capabilities, low power consumption, and ease of development. The STM32 series can be divided into several sub-series based on its core architecture, including the STM32F103 "Enhanced", STM32F101 "Basic", STM32F105, and STM32F107 "Interconnected", etc.
[0025] The dust sensor 111 uses the GP2Y1010AU0F module. The GP2Y1010AU0F infrared light scattering particulate matter sensor emits light through an infrared emitter to irradiate particulate matter in the air, and uses a receiver to detect the intensity of the scattered light, thereby realizing the detection of particulate matter concentration in the air.
[0026] like Figure 4 As shown, the voltage sampling unit 113 uses a resistive voltage divider sensor. Figure 3In this circuit, R21~R26 act as an adjustable resistor R. The resistance value is selected to ensure that the sampled voltage value is within the sampling range that the control chip can calculate, while preventing the resistor from burning out due to excessive current. Then, R and R28 are connected in series to divide the voltage. After passing through the filter circuit composed of R27, C212 and R29, C213, the signal is sent to the high-precision A / D sampling port of the main control chip.
[0027] like Figure 5 The diagram shown is the circuit schematic of current sampling unit 114. In the current sampling circuit, R61 is a manganin resistor with extremely low resistance, only 3 mΩ. Almost all the current flowing through the circuit passes through the manganin resistor.
[0028] The term "splitter" refers to the current being diverted. The voltage across the manganese-copper plate at this point is the sampled signal, from which the current flowing into the circuit can be determined.
[0029] like Figure 6 As shown, the PWM control module 116 uses an optocoupler chip. The PWM pin in the diagram is connected to the main control chip pin. The main control chip controls the duty cycle of the PWM pin based on information sent from the master system, thereby controlling the brightness of the LED.
[0030] The working principle of this utility model is as follows:
[0031] like Figure 1 As shown, multiple explosion-proof lights are wirelessly connected to a Bluetooth router. The Bluetooth router 2 is wirelessly connected to the main station 4 via a 4G / 5G network 3. The main station server monitors the environmental data corresponding to the multiple explosion-proof lights.
[0032] like Figure 2 As shown, the combustible gas sensor 110, dust sensor 111, and temperature sensor 112 are used to collect the concentration of combustible gas, dust concentration, and temperature of the working environment where the explosion-proof lamp is located. These environmental parameters are related to the operation of the explosion-proof lamp. The operating voltage and current of the explosion-proof lamp are collected by the voltage sampling unit 113 and the current sampling unit 114. These parameters are sent to the Bluetooth router 2 via the Bluetooth module. The Bluetooth router 2 supports Bluetooth and 4G / 5G communication. After receiving the sensor signals transmitted via Bluetooth communication, the Bluetooth router 2 then sends them to the main station via 4G / 5G communication. At the same time, when the detected concentration of combustible gas, dust concentration, temperature, voltage, or current exceeds a certain threshold, the PWM control module 116 controls the status indicator unit 17 to flash a red light as a warning. On-site personnel can take measures to avoid on-site safety accidents, such as temporarily shutting down or ventilating the area.
[0033] It should be noted that there are no specific limitations on the models of the aforementioned sensors and Bluetooth routers, and their models do not affect the implementation of this utility model.
[0034] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
