Problems solved by technology

[0007] (2) Pressing the light switch button frequently will greatly increase the workload of the train driver, and it is easy to distract the train driver's attention during driving, which may cause accidents
[0008] (3) This control method is too subjective, and the sensitivity is low, and the energy saving efficiency is not high

Embodiment

[0022] An energy-saving control device for a rail transit train compartment lighting system. The energy-saving control device includes a light sensor 1 and an automatic voltage regulator 2. The light sensor 1 is arranged on the top of the head of the rail transit train 3 at both ends, such as figure 1 As shown, the voltage automatic regulator 2 is set at the voltage input end of the lighting circuit, such as figure 2 Shown. The light sensor 1 measures the intensity value of natural light outside the carriage in real time, and transmits the signal to the automatic voltage regulator 2. The automatic voltage regulator 2 receives the natural light intensity signal outside the car, and automatically adjusts the input voltage of the lighting circuit according to different light intensity values, and adjusts the brightness of the lights in the car. The voltage automatic regulator 2 receives and selects the two light sensors 1 to measure the value. A smaller value to adjust the voltage...

Abstract

The invention relates to an energy-saving control device for the lighting system of rail transit train compartments. The lighting device includes a light sensor and an automatic voltage regulator. input. Compared with the prior art, the present invention can solve the serious waste of electric energy of the lighting system in the train when the train is running on the viaduct or the ground track, and the unscientific energy-saving method of the lighting system in the train compartment causes the loss of the lighting equipment in the train to be aggravated, and the life of the equipment is seriously shortened In order to ensure that the light intensity in the compartment is always maintained within a certain range of appropriate values, try to avoid the waste of electric energy caused by the unnecessary intensity value of the lighting and the loss caused by frequent switching of fluorescent lamps.

Description

Technical field [0001] The invention relates to an energy-saving control device, in particular to an energy-saving control device of a rail transit train carriage lighting system. Background technique [0002] Since the 1990s, China’s urban rail transit has been in a period of vigorous development. At the same time, the huge demand for power resources has also become one of the important issues facing the highly networked and electrified subway operation. At present, most of the design and research and development of hardware equipment related to subway operations, such as subway trains and communication systems, are done by foreign companies. This causes the operating parameters of some electrical appliances to not fully meet the specific requirements of domestic line operation, which will cause equipment It is inconvenient to use or wastes power resources to varying degrees. [0003] Through investigation and research, we found that, due to the circuit design, all the lights in ...
