Abstract
The utility model provides a high-precision electric quantity monitoring device for a lead-acid storage battery. The high-precision electric quantity monitoring device comprises an LED indication lamp, a power management module, a main control module and a display module which are connected in order. The power management module monitors electricity consumption, temperature, capacity, battery ID and battery state of the storage battery, drives the LED indication lamp to display residual electric quantity with an increment of 20%, carries out communication with the main control module by using an HDQ protocol, and sends a value of a relevant register to the main control module. The main control module performs corresponding processing on the collected data and the display module displays the processing results.
Description
Technical field
The utility model relates to a kind of electric quantity monitoring device, especially lead-acid accumulator high precision electric quantity monitoring device.
Background technology
Accumulator is widely used in fields such as traffic, communication, control system as the long period power supply.Be guaranteeing the stability of using electricity system, is a very important job to the monitoring of accumulator dump energy, and detection method commonly used has: densimetry, open-circuit voltage method, electric discharge and internal resistance method.The shortcoming of these 4 kinds of methods is that measuring accuracy is low, is not suitable for on-line measurement, and complex circuit designs or algorithm are loaded down with trivial details.
Summary of the invention
In view of above reason, the utility model provides a kind of lead-acid accumulator high precision electric quantity monitoring device.It can high precision, information such as on-line monitoring accumulator dump energy, current voltage, battery temperature in real time, and periphery circuit design is simple, adopts HDQ Integrated Service Digital Network letter agreement.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of lead-acid accumulator high precision electric quantity monitoring device, comprise LED light, power management module, main control module, display module, it is characterized in that LED light, power management module, main control module, display module connect successively.Power consumption, temperature, capacity, battery ID, the battery status of power management module monitoring accumulator, and the driving LED pilot lamp is with 20% increment demonstration dump energy, adopt HDQ agreement and main control module to communicate, send the value of related register to the main control module, main control module then handles accordingly the data that collect, and is shown by display module.
The beneficial effects of the utility model are, can high precision, information such as on-line monitoring accumulator dump energy, current voltage, battery temperature in real time, have advantages of high practicability.
