Compared with the prior art, the invention solves the isolated communication problem of multiple terminals (more than 100 terminals) in the system, as well as the discharge problem of leading single batteries during on-line maintenance.
Description
Technical field
The present invention relates to a kind of batteries maintenance system, especially relate to a kind of large-scale batteries automatic maintenance system.
Background technology
Operation mechanism, failure mode at storage battery, real-time online detects the operating state of each cell of batteries, analysis according to testing result, carry out on-line maintenance to falling behind cell, each cell that guarantees batteries has consistency preferably, makes batteries can reach normal useful life.Prior art generally is used for low-voltage (DC60V) batteries, be used for DC220V high-power battery group automatic maintenance system, and the discharge of cell when the isolated communication of multiple terminals, on-line maintenance just exists defective.
In little part, buses such as general RS485, RS232 can't resolve in the system isolated communication problem greater than 100 terminals without Ethernet.
In the existing storage battery group automatic maintenance system, because the power of batteries is little, to discharging and recharging of the carrying out quota of cell, energy consumption problem is outstanding.So simple processing in high-power system, not only the restriction that is subjected to environment for use is given prominence to but also implemented to energy consumption problem.
Summary of the invention
Purpose of the present invention is exactly the large-scale batteries automatic maintenance system that a kind of on-line maintenance is provided for the defective that overcomes above-mentioned prior art existence.
Purpose of the present invention can be achieved through the following technical solutions:
A kind of large-scale batteries automatic maintenance system, it is characterized in that, this system comprises host computer, a plurality of slave computer, a plurality of photoisolator, communication bus, 485 switching drivers, discharges and recharges controller switching equipment, described a plurality of slave computer one end is connected with each cell of batteries, the other end is connected with each photoisolator, described a plurality of photoisolator is connected with host computer through 485 switching drivers by communication bus, the two ends of described batteries respectively with host computer, 485 transfer drivers, discharge and recharge controller switching equipment and be connected.
Described a plurality of slave computer is corresponding one by one with cell in the batteries.
Be provided with the DC/DC circuit between described batteries and the 485 switching drivers.
Compared with prior art, the present invention has the following advantages:
1, utilize the design of communication bus, 485 switching drive units to solve the isolated communication problem of system multiple terminals (greater than 100 terminals).
2, utilize the scheme that to charge to the cell that falls behind from the power taking of batteries electrical network, allow leading cell discharge problem when having solved on-line maintenance.
3, realized that all filling all of each cell put, improved the useful life of batteries greatly.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
The present invention is described in detail below in conjunction with the drawings and specific embodiments.
Embodiment
As shown in Figure 1, a kind of large-scale batteries automatic maintenance system, this system comprises host computer 4, a plurality of slave computer 2, a plurality of photoisolator 3, communication bus 6,485 switching drivers 5, discharges and recharges controller switching equipment 1, described a plurality of slave computer 2 one ends are connected with each cell of batteries, the other end is connected with each photoisolator 3, described a plurality of photoisolator 3 is connected with host computer 4 through 485 switching drivers 5 by communication bus 6, described batteries respectively with host computer 4,485 transfer drivers 5, discharge and recharge controller switching equipment 1 and be connected.
The function of host computer 4 is detection data of analysis, each cell of computing batteries, the detection and the maintenance of 2 pairs of cells of control slave computer.Host computer of a system links to each other with slave computer by 485 buses.
The function of slave computer 2 is under the control of host computer cell to be detected, the data that detect are sent to host computer 4, carries out the maintenance work instruction of host computer 4.The corresponding slave computer 2 of each cell, slave computer 2 hangs on the communication bus, and communication bus 6 inserts 485 interfaces of host computer 4 through 485 switching drive units 5.
The power supply of all terminals (slave computer 2,485 switching drive units 5, host computer 4) is all finished by batteries, the discharge problem of cell when doing the electric isolating problem that not only solved between each terminal but also software control that can system like this and solving on-line maintenance.
The consistency of each cell of batteries is the basic assurance that batteries can reach normal useful life.Yet, just can not be consistent from each cell of beginning batteries that dispatches from the factory, can only pursue consistency preferably when dispatching from the factory.Each cell of batteries is shared weal and woe in the process that batteries is used, and the cell that makes leading cell overcharge, fall behind is crossed and put, and the non-benign circulation must cause the consistency of batteries to degenerate like this, and sharply descend useful life.
Operation principle of the present invention is exactly at above-mentioned situation, real-time online is to the detection of cell, the power supply that provides with batteries charges to the cell (cell that terminal voltage is low) that falls behind under the charge and discharge state, just can avoid batteries each cell state of sharing weal and woe in use, constantly repair the consistency of batteries, better the normal useful life of maintenance free cell group.
