Device and system for monitoring and alarming faults of storage battery

Abstract

The invention discloses a device and system for monitoring and alarming faults of a storage battery. The device for monitoring and alarming faults of the storage battery comprises a double-channel single body measuring module of the storage battery, an environment temperature measuring module and a fault alarming module, wherein the double-channel single body measuring module of the storage battery is used for detecting the temperature of two parts of a single storage battery respectively through two channels and submitting the temperature difference of the single storage battery; the environment temperature measuring module is used for measuring the environment temperature of the single storage battery; and the fault alarming module is used for judging whether the single storage battery has faults or not according to the temperature difference of the single storage battery and the environment temperature and alarming when the single storage battery has faults. In the device and the system for monitoring and alarming faults of the storage battery, the temperature difference of the upper part and the lower part is obtained through measuring the temperature of the upper part and thelower part of the storage battery, the storage battery can be accurately judged whether to have the faults of thermal runaway or corrosion water loss short circuits, and the like or not, and the device can alarm in time when the storage battery has faults so as to prevent major accidents such as fire disasters, and the like caused by the faults of the battery.

Description

technical field [0001] The invention relates to a mobile communication power supply technology in the communication field, in particular to a storage battery failure monitoring and warning device and system. Background technique [0002] In the prior art, the environmental power centralized monitoring system is composed of four mutually exclusive parts: high and low voltage power distribution monitoring system, communication power monitoring system, central air-conditioning monitoring system, and special air-conditioning monitoring system. In order to meet the requirements of system maintenance and development, the remote monitoring system should adopt an inverted tree network topology connected step by step, consisting of a monitoring center and distributed monitoring end offices. [0003] At present, the power environment monitoring is generally more "monitoring" and less "controlling". The number of monitoring points is far greater than the number of control points, but i...

Problems solved by technology

[0005] In the process of realizing the present invention, the inventor found that in the prior art, the monitoring of the power environment temperature adopts single-point monitoring, and the temperature measurement point is at the top of the battery, while the battery has a single thermal runaway or a short circuit of the plate, and the positive plate is corroded. The heating of the water short circuit fault occurs from the bottom of the battery, so the reported alarm information that exceeds the normal range during the operation of the power equipment or environmental parameters does not match the actual situation.
