Embodiment Construction

[0036] The present invention will be described in detail below in combination with specific embodiments.

[0037] The present invention relates to a distributed control method for railway tunnel lighting fixtures based on wireless Internet of Things technology. The method is realized through the following steps:

[0038] Step 1: Obtain a single-phase AC 220V power supply. After isolation by the power failure detection isolation module, it is adjusted to a DC constant current with an adjustable voltage of 30V to 50V through the electromagnetic filter rectifier circuit, PFC circuit, switching circuit, isolation transformer and rectifier filter circuit. source, supplying power to lamps;

[0039] Step 2: The control circuit collects the circuit data in real time and compares it with the reference value, and transmits the instruction to the PWM modulation circuit, and the PWM modulation circuit controls the output of the switching circuit according to the instruction value, forming...

Abstract

The invention relates to a railway tunnel lighting lamp distributed control method based on the wireless Internet-of-Things technology, and the method comprises the steps: obtaining a single-phase alternating-current 220V power supply, adjusting the single-phase alternating-current 220V power supply into a direct-current constant-current source with the adjustable voltage from 30V to 50V, and supplying power to a lamp; enabling the control circuit to collect circuit data in real time, comparing the circuit data with a reference value, transmitting an instruction to the PWM modulation circuit,and controlling the switching circuit to output; and enabling an Internet-of-Things module to upload the collected circuit data to local and remote user control terminals in a wireless and wired communication mode, and controlling the state of the lamp according to a user operation instruction. The railway tunnel lighting lamp distributed control method has the functions of circuit and network fault isolation, mesh topology wireless ad hoc network and wireless communication, and has the functions of short circuit, overcurrent, overload, overvoltage, over-temperature and other lamp body and control circuit fault isolation and wireless communication network fault isolation.

Description

technical field [0001] The invention belongs to the technical field of railway tunnel lighting, and in particular relates to a distributed control method for railway tunnel lighting lamps based on wireless Internet of Things technology. Background technique [0002] The existing railway tunnel lighting system still uses the segmented control method based on branch cable control. In addition to the main lighting cable, lighting branch cables are also provided in the tunnel according to the needs of lighting segment control. Through the control of the lighting branch For segmental control of tunnel lighting, the length of the lighting main line is generally within 1500 meters, and the length of the lighting branch line is within 750 meters. This control method makes the low-voltage power distribution system more complicated; when performing inspections or maintenance operations, the on-site personnel can only switch and switch lamps in the control boxes at the first and last s...
