The invention discloses an air valve controller of a subway, which comprises an input system, a singlechip system, a state display system, a motor drive system and a power supply. The system belongs to the field of intelligent transportation control, solves the problem of air valve control of the subway and provides inexpensive and stable equipment for the ventilation control of the subway. The controller can remotely control and can locally control, and the control mode can be selected on a control panel; a control signal enters the singlechip system through the input system; a singlechip judges whether a motor is started or not according to the state of the air valve of the subway, i.e. positively rotating or negatively rotating; and the motor stops rotating when the air valve moves to the specified position detected by a limit switch, and the state display system displays the state of the air valve. The controller can be used for the control of various air valves of the subway, butnot to be limited to the subway, and the air valves in other places can be controlled by the controller.
Description
technical field [0001] The invention relates to a subway damper controller. In particular, it relates to a subway air valve controller with simple structure, flexible control, high reliability and low cost. Background technique [0002] In recent years, my country's urban transportation construction has developed rapidly along with the pace of economic development, and rail transit construction is an important part of it. As a safe, comfortable, fast, punctual and environment-friendly high-capacity passenger transportation tool, urban rail transit has been recognized by everyone. Though this has solved the traffic congestion problem that brings because of urban population rapid growth, but new problem has produced, because subway is mostly in the underground closed space, the ventilation and fire problem in the subway arouse people's widespread concern day by day. The occurrence of subway fires at home and abroad fully proves that not only fires will break out in subway st...
