Description

System for on-line monitoring of running quality of battery

Technical field

The present invention relates to a kind of system for on-line monitoring of running quality of battery.

Background technology

Just often the battery pack in the straight-flow system is in the floating charging stand-by state, and when the alternating current dead electricity, accumulator provides energy to the accident load rapidly.As all kinds of straightway pumps, emergency lighting, interchange uninterruption power source, forced outage, isolating switch breaker tripping and closing etc., the loads such as control, signal, aut.eq., protective device and communication when also being necessary for forced outage simultaneously provide electric power.Therefore accumulator is as stand-by power source under the accident condition that exchanges dead electricity.In telecommunications industry, very pay attention to the maintenance work of accumulator, comprise the operation and maintenance of analysing valve control type lead-acid accumulator battery, as follows to the Maintenance Significant Items of accumulator usually:

1.1 the property checked that the valve-control storage battery group after new installation or the overhaul is carried out discharges and recharges;

1.2 the floating charging when normally moving;

1.3 in service improper in order to remedy because of the floating current adjustment, do not compensate the loss of self-discharge of battery and accumulator capacity that creepage electric leakage causes, set 1~3 month, automatically carry out the boost charge of a constant-current charge-constant-voltage charge-floating charging;

1.4 when battery pack during in grid disconnection or fault, AC interruptions, through after the accident discharge electric battery terminal voltage being descended.When exchanging power up and send electricity, the charging device automatic or manual enters the automatic/hand charging of constant-current charge-constant-voltage charge-floating charging.

Recently in telecommunications industry, more and more pay attention to maintenance, require to reach and go up a declaration form cell voltage form every day accumulator.But fact proved that for the battery that is in floating charge state, the performance difference between the battery (based on capacity volume variance) is difficult to show.

Summary of the invention

The objective of the invention is to realize maintenance and monitoring to all kinds of electric storage batteries in place such as generating plant, electric substations, improve electric storage battery maintenance levels, reduce the accumulator failure rate.

The objective of the invention is to be achieved through the following technical solutions:

A kind of system for on-line monitoring of running quality of battery, comprise host computer, dispatcher, terminal, described host computer, dispatcher, terminal connect by the CAN bus, the related data of the measurement single battery voltage of terminal, temperature, internal resistance etc. may be displayed on the terminal LCD Panel, judge the quality of accumulator simultaneously, show the fail battery parameter; Simultaneously, send measurement data and information to host computer by the CAN bus; Host computer is uploaded data through network to dispatcher by RS232 or RS485 interface.

Beneficial effect of the present invention is: native system can on-line monitoring and is gathered voltage, electric current, the internal resistance of cell and the temperature parameter of single battery in real time, calculate the residual capacity of battery, reply host computer inquiry and operation, fail battery is made corresponding alarm prompt, can in time find dead battery, to guaranteeing that safe, the raising power supply reliability of direct supply prolong the serviceable life of whole group storage battery, decisive role effectively.

Description of drawings

With embodiment the present invention is described in further detail with reference to the accompanying drawings below.

Fig. 1 is the structural drawing of the described system for on-line monitoring of running quality of battery of the embodiment of the invention.

Among the figure:

1, host computer; 2, dispatcher; 3, terminal; 4, CAN bus.

Embodiment

As shown in Figure 1, system for on-line monitoring of running quality of battery of the present invention, comprise host computer 1, dispatcher 2, terminal 3, described host computer 1, dispatcher 2, terminal 3 connect by CAN bus 4, the related data of the measurement single battery voltage of terminal 3, temperature, internal resistance etc. may be displayed on terminal 3 LCD Panel, judge the quality of accumulator simultaneously, show the fail battery parameter; Simultaneously, send measurement data and information to host computer 1 by CAN bus 4; Host computer 1 is uploaded data through network to dispatcher 2 by CAN bus RS232 or RS485 interface.

Measurement function: can measure (or setting measurement time) at any time and write down total voltage, the total current of battery pack in service, each monomer battery voltage, internal resistance and temperature data.

Utilize the monitoring mode of fuzzy query that the internal resistance situation of change of each cell of battery pack is provided, and judge operating accumulator quality in the comprehensive evaluation mode.

Automatically calculate the residual capacity of whole group and single-unit accumulator, understand accumulator in service remaining capacity at present.

Abnormality alarming: when accumulator battery voltage, internal resistance and temperature are diagnosed as when unusual, send fault warning, possess unattended function.

Can list the related data real-time parameter of single battery voltage, temperature, internal resistance by LCD Panel on the spot, judge the quality of accumulator simultaneously, show the fail battery parameter.

All measurement data and information are communicated by letter with host computer 1 by CAN bus 4 forms.

The online cruising inspection system of this battery can detect information such as gathering cell voltage, internal resistance, temperature, and realizes that data sync uploads, and carries out monitoring display by 1 pair of battery information of host computer.

Wherein the battery temperature collection is the collection that realizes the temperature simulation amount by MAX6613, the switching of analog switch control battery sequence number, switch the battery sequence number and simultaneously the temperature simulation amount of gathering is sent into master cpu, after the A/D digitizing, carry out algorithm process again, thereby realize acquisition monitoring each battery surface temperature.

Voltage acquisition is to switch the battery location that will detect by relay, (this system is by three shelves levels to choose measurement shelves level in advance according to the battery standard voltage that will detect, maximum detection amount voltage is 15V), in relay switching position information, measure mouth and give master cpu by penetrating with circuit with battery voltage information, after the A/D digitizing, carry out algorithm process again, thereby obtain battery voltage information.

The detection of the internal resistance of cell is the interchange disturbing signal that 30Hz is provided by a fixed signal source, and the conducting by relay is added to the battery two ends that will detect, measures the internal resistance of cell by exchanging method of perturbation.
