Abstract

The invention discloses a communication machine room battery pack online monitoring equipment and monitoring method. The equipment comprises a Hall current sensor, an MOS switch, a single-chip microcomputer and a signal processing module. The Hall current sensor is connected in series in the floating charging line of the storage battery pack and the charger. n storage batteries are connected in series to form n+1 nodes, and each node is connected with an electric control line and a detection line. The electric control line is connected with the drain electrode of the MOS switch through a loadresistor and also connected with the signal processing module. The detection line is directly connected with the signal processing module. The Hall current sensor, the gate electrode of the MOS switchand the signal processing module are connected with the single-chip microcomputer. The beneficial effects of the communication machine room battery pack online monitoring equipment and monitoring method are that the user can monitor the performance state of the storage battery pack in real time under the condition of simple installation without disconnecting the original line connection so that the reliability of the system can be enhanced and the possibility of the human error and inaccuracy of manual measurement can be omitted.

Description

technical field [0001] The invention belongs to the technical field of battery monitoring, and in particular relates to an online monitoring device and a monitoring method for a battery pack in a communication machine room. Background technique [0002] The communication room uses a battery pack as a -48V backup power supply. Under normal conditions, the backup battery pack is always in a state of micro-current floating charge. Because the battery pack uses 24 2V batteries in series, the aging or failure of one of the batteries will cause the overall failure of the backup power supply, so it is very important to be able to regularly detect the status of each battery. The backup power supply in the communication room is a key system equipment, so the battery pack must not be disconnected from the main line, that is, the battery pack on-line monitoring system must only be connected in parallel to the battery pack. [0003] At present, regular manual inspection is widely used ...
