Problems solved by technology

During this process, since there is no staff to check the working condition of the battery for a long time, these wireless terminal devices may run incorrectly without anyone noticing. If the battery works abnormally after the mains power is cut off, it may cause circuit damage or Equipment damage may also affect the function of the overall system, resulting in the loss of some important data, which brings a huge test to the power maintenance system of the communication room and base station

Abstract

The present invention provides a bidirectional inverter, which includes a micro-control module, an MPPT controller, a SPWM signal generator, a DC / DC converter, a DC / AC converter, a switch TY1 and a switch TY2; the micro-control module is connected to the control board , load unit and charging unit. The present invention also provides a remote charging and discharging maintenance system, which includes a control board, a feedback power supply module and a central monitoring platform; the feedback power supply module includes a bidirectional inverter, a load unit and a charging unit electrically connected thereto. The bidirectional inverter of the present invention can greatly save the workload of the bidirectional inverter. Through the remote charging and discharging maintenance system of the present invention, when the staff needs to perform remote maintenance and detection on the battery pack, they can interact with the central monitoring platform, so that the staff can check the charging and discharging status of the battery and the working status of the external mains in real time.

Description

technical field [0001] The invention relates to the technical field of battery application, in particular to a bidirectional inverter and a remote charging and discharging maintenance system. Background technique [0002] With the rapid development of information technology and increasing demand, the number of communication equipment rooms and base stations has also increased rapidly. At the same time, the communication room and the base station are basically unattended, and the wireless terminal equipment will be out of direct contact with the staff for a long time and operate in the form of automatic charging and discharging. During this process, since there is no staff to check the working condition of the battery for a long time, these wireless terminal devices may run incorrectly without anyone noticing. If the battery works abnormally after the mains power is cut off, it may cause circuit damage or Equipment damage may also affect the function of the overall system, r...
