With the continuous development of intelligent building technology, the number of systems and equipment it contains is also increasing, in order to allow users to quickly and easily understand the operating fault status of building equipment and the control of certain equipment, BMS system is born.

BMS (Battery Management System, BMS) system is located between the basic equipment control layer and the information management of the building intelligent management system, and is the bridge between the communication control system and the information management system. Through the BMS system, users can centrally monitor the operating status of various building equipment, count the operating parameters of the equipment, and allow users to network from local or mobile terminals to monitor and manage the battery system in real time. It has a reliable linkage function to deal with emergencies in a timely manner.

Main modes of BMS system integration:

●System integration by hard contact

●System integration by serial communication

●System integration with building automation system BA as the platform

●System integration based on subsystem equality

Common systems integrated with BMS systems:

●Building Automation System (BA)

●Integrated Security System (SA)

●Fire protection system (FA)

Due to the position of the BMS system in intelligent buildings, it has the following characteristics:

●High technical content;

●Flexible access subsystem according to actual needs;

●Strong dependence on subsystems and their communication protocols;

● There are not many truly mature products;

where the table is the voltage data and temperature of the 8-cell battery monitoring S E C U, below the table is a graph showing the voltage of a certain battery, above the table is specific data about all S E C U, and on the right side of the table is H i s t o r i C a l D a t a is to view the historical data of the battery. The above options S e c u i D and B a t N o are used to allow the user to choose to monitor the voltage of a specific battery.

When the data exceeds the voltage, the user needs to set the number of the SMS recipient first, and then just connect the SMS sending template, and then turn on the function to send an alarm to the customer or supplier, the user can set the upper and lower limit of the battery voltage and the upper limit of the temperature, which is conducive to adapting to the user's working environment factors.

in the control page below to set the relevant information of the SMS sending number, at the same time , you can also set the number of queries S E C U, as well as the address of the connection to the S Q L database, save the data, in addition to the S Q L database, there is A C C E S S local database, when you cannot connect to the S Q L database, the data will be saved to the A C C E S S local database.

The figure below is a mechanical I D Make changes

This page is used to switch the working mode of B M S, the user can set a certain period of time, change the working state of the relay switch and change the working type of B M S, there are 6 fixed working states below, of which T e s t is used for testing, and can switch S 1 S at any time 2 switch to change the current working state, and the upper right corner is to write the time to B M S, which can be used to test whether the set working state is running normally (note: the switching time is based on the time in the microcomputer, not the time on the computer) or modify the clock time in the microcomputer B
