Embodiment Construction

[0029] The present invention will be further described below in conjunction with accompanying drawing.

[0030] see Figure 1-3 , The temperature control device of the trackside cabinet of the present invention includes: a temperature acquisition unit 1 , a temperature control unit 2 and an execution unit 3 .

[0031] The temperature collection unit 1 is used to collect the temperature data of the trackside cabinet. The temperature control unit 2 calculates and processes the temperature data, and outputs PID control coefficients. The execution unit 3 adjusts the temperature of the trackside cabinet according to the PID control coefficient.

[0032] The temperature acquisition unit 1 includes a plurality of temperature sensors 11, 10 in this embodiment, and OMRON E52-CA1D is selected. Five temperature sensors 11 are respectively symmetrically installed on the top and bottom of the trackside cabinet, and a temperature sensor 11 is installed at the intersection of the diagonal...

Abstract

The invention discloses a temperature control device and a temperature control method for a trackside cabinet. The temperature control device comprises a temperature acquisition unit used for acquiring temperature data of a trackside cabinet; a temperature control unit used for calculating and processing the temperature data and outputting a PID control coefficient; and an execution unit used for adjusting the temperature of the trackside cabinet according to the PID control coefficient. According to the invention, the temperature of the cabinet can be actively controlled without depending on environmental conditions of an equipment room.

Description

technical field [0001] The invention relates to the field of temperature control, in particular to the temperature control of a trackside cabinet. Background technique [0002] In the current rail transit signal system, the temperature of the cabinets in the trackside equipment room is controlled by the temperature regulating device in the equipment room. In some temporary equipment rooms and some equipment rooms with poor conditions, the signal cabinet is limited by the conditions of the equipment room, and the temperature may be out of control, which will cause the signal system to go down or malfunction. Therefore, active temperature control of trackside cabinets needs to be implemented. Contents of the invention [0003] The object of the present invention is to provide a temperature control device and method for a trackside cabinet, which can actively control the temperature of the cabinet without depending on the environmental conditions of the equipment room.
