Problems solved by technology

The traditional electric locomotive control circuit uses an active grounding device, that is, when the locomotive is grounded, the battery will be directly connected to the grounding loop, and multi-point grounding is used, but this will greatly affect the stability of the power supply of the control system , resulting in the short circuit of the control power supply caused by multi-point grounding, and it does not have the function of undervoltage alarm

Embodiment Construction

[0018] The accompanying drawings show an embodiment of the present invention, and the present invention will be further described below in conjunction with the accompanying drawings.

[0019] As can be seen from the accompanying drawings, the present invention is a control power grounding and undervoltage alarm device, all the electrical circuits that need to be controlled power grounding and undervoltage alarm are input into a control power grounding and undervoltage alarm device, and the control power grounding And the undervoltage alarm device analyzes the status of the grounding and undervoltage of the control power supply by sampling and processing the voltage. When the grounding of the control power supply and the undervoltage alarm device detects that the grounding or undervoltage of the control power supply is A high level signal is given to drive the buzzer to alarm. The control power supply grounding and undervoltage alarm device includes a single-chip microcomputer ...

Abstract

The invention connects all electric wirings needed to carry out control power supply grounding / undervoltage (CPSGU) to device of CPSGU alarm. Sampling voltage, the device of CPSGU alarm processes, analyzes state of CPSGU. After detecting CPSGU, the device of CPSGU alarm sends out signal in high level to drive buzzer alarming.

Description

technical field [0001] The present invention relates to a locomotive electrical protection device and its control method, in particular to a locomotive control power supply grounding and undervoltage alarm device and its control method, mainly used in various electric locomotive control power supply grounding and undervoltage protection systems middle. Background technique [0002] As an electrical control system, in order to ensure safety, it is generally necessary to ground each electrical device. The traditional electric locomotive control circuit uses an active grounding device, that is, when the locomotive is grounded, the battery will be directly connected to the grounding loop, and multi-point grounding is used, but this will greatly affect the stability of the power supply of the control system , resulting in the short circuit of the control power supply caused by multi-point grounding, and it does not have the function of undervoltage alarm. Therefore it is necess...
