Electric energy meter system capable of monitoring electric quantity of storage battery

Abstract

The present invention discloses an electric energy meter system capable of monitoring the electric quantity of a storage battery. The electric energy meter system capable of monitoring the electric quantity of the storage battery comprises a main control display module, an AC electric energy acquisition module, a DC electric energy acquisition module and a control output module, and the DC electric energy acquisition module is equipped with a monitoring element used for monitoring the electric quantity of the storage battery. According to present invention, by arranging the monitoring element used for monitoring the electric quantity of the storage battery in the DC electric energy acquisition module, the electric quantity of the storage battery of a communication base station can be monitored real-timely, thereby being convenient and simple, and being easy to realize.

Description

technical field [0001] The invention belongs to the field of communication equipment, and in particular relates to an electric energy meter system capable of monitoring the remaining power of a lead-acid battery used in a communication base station. Background technique [0002] With the rapid development of communication services, communication base stations are spread all over cities, towns and villages, please refer to Figure 1 , which is a schematic diagram of centralized power supply for communication base stations. Generally, each base station is equipped with two sets of valve-regulated lead-acid batteries with a capacity of 300A~500A. The charging method adopts floating charging or equalizing charging. When there is mains power supply, because the battery pack and the load are connected in parallel, the AC / DC rectifier supplies power to the load and is also responsible for charging the battery. Usually, the battery pack is always fully charged. , when the mains powe...

Problems solved by technology

The charging method adopts floating charging or equalizing charging. When there is mains power supply, because the battery pack and the load are connected in parallel, the AC / DC rectifier supplies power to the load and is also responsible for charging the battery. Usually, the battery pack is always fully charged. , when the mains power fails or the rectifier fails, the battery pack supplies power to the load, but the battery power supply time is limited, and the diesel engine must be started before the battery is emptied and an alarm is sent to the intelligent monitoring center to remind relevant personnel to deal with it as soon as possible. During this period (especially It is because the battery will age due to the influence of other factors such as the number of times of use over time) How much real-time power is left in the battery pack and how long can it last? There is no fuel gauge similar to an oil gauge for estimation / timely display and alarm of remaining power , which brings great inconvenience to the use of electric energy meter components
