Title:
RAILWAY VEHICLE AND HEATING CONTROL SYSTEM AND METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2024/077824
Kind Code:
A1
Abstract:
A railway vehicle and a heating control system and method therefor. The heating control system comprises a temperature sensor (8), a control module (2), and a variable-frequency power supply module (3). The temperature sensor (8) is electrically connected to the input end of the control module (2). The input end of the control module (2) is further communicationally connected to an air conditioner controller or a vehicle control unit. The output end of the control module (2) is electrically connected to the input end of the variable-frequency power supply module (3). The magnitude of the driving voltage output by the variable-frequency power supply module (3) is accurately controlled according to the difference between a set temperature and the actual temperature in a compartment, and a heating device (6) outputs the heating capacity in equal proportion to the driving voltage according to the magnitude of the driving voltage, so that the heating capacity output by the heating device is matched with the heating load, the comfort is improved, and energy is saved. A driving power supply of the heating device uses the variable-frequency power supply module, soft start of the heating device is realized by using frequency conversion control, and impact on a vehicle auxiliary power supply or a power grid is avoided.
