Embodiment Construction

[0026] An air-conditioning controller for a train environment provided by the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0027] figure 2 It shows an air conditioner controller for train environment with DC 110V power supply and DC 110V switch input according to an embodiment of the present invention. like figure 2 As shown, the air conditioner controller includes: a man-machine interface circuit, one or more DC110V switch input circuits, switch output circuits, a central logic processing circuit and a power supply circuit.

[0028] Each DC110V switching value input circuit is used to receive the status signal of the train air-conditioning components, and transmit the information of the status signal to the central logic processing circuit. Among them, these state signals are all DC 110V level signals, including the start and stop states of compressors, condensers, fans, electric heaters, sol...

Abstract

The invention provides an air-conditioning controller for a train environment, which comprises a power supply circuit, a central logic processing circuit and an on-off output circuit. The air-conditioning controller also comprises one or more DC 110V on-off input circuits for being connected with a train air-conditioning part with DC 110V output voltage and receiving a state signal of the train air-conditioning part; the DC 110V on-off input circuits are supplied with power by the power supply circuit and used for forwarding the received state signal of the train air-conditioning part to the central logic processing circuit; and the central logic processing circuit outputs a DC 110V control signal to the train air-conditioning part by the on-off output circuit according to the state signal of the train air-conditioning part and a user command. By applying the invention, the air-conditioning controller with a single control circuit can be used for adjusting the level of the control signal of the whole train environment and power supply voltage in a train, which greatly saves finite space in the train and reduces the train cost.

Description

technical field [0001] The present invention relates to the technical field of power conversion, and more specifically, the present invention relates to an air conditioner controller used in a train environment. Background technique [0002] At present, air conditioners have become standard equipment for passenger trains. figure 1 Shows the air conditioning control system in the existing train environment, usually, as figure 1 As shown, the control voltage of the train adopts DC 110V, while the switch input port of the traditional air conditioner controller can only handle the signal of DC 24V, so a large number of intermediate relays are required for level conversion for each component of the air conditioner. At the same time, traditional air conditioner controllers use DC24V or AC 220V for power supply, but when used to control train air conditioners, an additional power conversion module needs to be added. Therefore, when the traditional air-conditioning controller is a...
