Problems solved by technology

[0004] Furthermore, due to the need to collect the data of each battery, a large number of wires need to be laid, resulting in complicated on-site wiring. A large number of collection wires lead to cumbersome wiring, messy wiring, and unnecessary difficulty in installation and maintenance. Improvements are needed for this

Abstract

The invention discloses a novel single storage battery voltage acquisition module, which comprises an acquisition unit and a line unit, and is characterized in that the acquisition unit comprises an acquisition loop, a conversion loop connected to the output end of the acquisition loop, and a communication loop connected to the output end of the conversion loop; the communication loop is provided with a bidirectional communication interface; the circuit unit is connected to the output end of the acquisition loop and comprises a connecting line and a terminal stud arranged at the end part of the connecting line; according to the invention, one-to-one acquisition is adopted, so that an acquisition loop is simplified, the false alarm rate is low, and the operation reliability is greatly improved; a novel terminal stud is adopted, connection and installation are convenient, later maintenance and overhaul are facilitated, and fault finding and processing are rapid.

Description

technical field [0001] The invention relates to the technical field of battery voltage acquisition, in particular to a novel battery voltage acquisition module. Background technique [0002] The single voltage collection of DC battery packs in substations generally uses multiple modules for collection, that is, one module collects multiple batteries, and uses three wires for collection (that is, 2 batteries and 3 wires). The line is connected to the battery acquisition module, and the acquisition module communicates the collected battery voltage data with the battery inspection instrument through the 485 line, centrally displays the collected data on the device, and uploads the data to the host computer or background monitoring system. When the collected data is abnormal, the device sends out an alarm signal, so that the abnormal condition of the battery operation can be found in time. With this collection method, the battery inspection device has too many links in the coll...
