Description

A kind of intelligent storage battery on-line monitor

Technical field:

The present invention relates to detecting instrument, especially relates to a kind of intelligent battery on-line detector.

Background technology:

Accumulator is a kind ofly electric energy can be converted into chemical energy and store, and chemical energy is changed into the power supply of electric energy during use again.It is a kind ofly power conveniently, safe and reliable direct supply, thereby obtained using widely in the every field of national economy.Because accumulator is a kind of chemical reaction equipment, its inner chemical reaction generally is difficult in time discovering, and the defective in the daily use can not come out by immediate response yet, so the maintenance work of accumulator is most important.A wherein very important maintenance work is that battery terminal voltage is measured, because the quantity of battery is a lot of in the electric battery, usually can only indicate battery to it measures, and can't accomplish every battery is all measured, therefore be difficult in time noting abnormalities battery, and if unusual battery can not get timely processing, phenomenon of the failure will be serious day by day, gently then cause battery capacity to reduce, heavy then will reverse electrode phenomena occur and damage other battery in the electric battery.

Summary of the invention:

The present invention is exactly at the problems referred to above, a kind of intelligent storage battery on-line monitor that can in time detect every battery.

For achieving the above object, the present invention adopts following technical scheme, the present invention includes collector, impact damper, analog to digital conversion, optocoupler, Single Chip Microcomputer (SCM) system, described Single Chip Microcomputer (SCM) system links to each other with the port of communication, printer, demonstration, warning, collector interface, Single Chip Microcomputer (SCM) system respectively, the another port of optocoupler links to each other with analog to digital conversion, analog-to-digital another port links to each other with impact damper, and the another port of impact damper links to each other with collector, and sampling thief links to each other with the collector port.

Beneficial effect of the present invention:

DC power system on-line monitoring instrument is to be the intelligence instrument of core with the single-chip microcomputer, its sampling principle novelty, method uniqueness, measuring accuracy height, good reliability, ratio of performance to price height.Can realize on-line monitoring to each accumulator in the battery pack, also alternative traditional artificial sign battery measurement is to finish automatic measurement, storage and the printing of all batteries.Thereby use that this instrument saves time, the laborsaving accuracy that also can improve measurement.It is extensive use of the maintenance effects can improve accumulator greatly, and can find the defective of battery as early as possible so that it is in time handled, reach the purpose of extending battery life.

Fig. 2 is the commutation circuit schematic diagram of two keys relay of the present invention;

Fig. 3 is the employing schematic diagram of suspension mensuration of the present invention.

Embodiment:

See Fig. 1, control system of the present invention comprises collector, impact damper, analog to digital conversion, optocoupler, Single Chip Microcomputer (SCM) system, described Single Chip Microcomputer (SCM) system links to each other with the port of communication, printer, demonstration, warning, collector interface, Single Chip Microcomputer (SCM) system respectively, the another port of optocoupler links to each other with analog to digital conversion, analog-to-digital another port links to each other with impact damper, the another port of impact damper links to each other with collector, and sampling thief links to each other with the collector port.

See Fig. 2, the two ends of each battery all are connected with two pairs of normal opened contacts of a two keys relay.When relay all was failure to actuate, all batteries all disconnected with the measurement loop like this.When needs are measured certain battery, pairing that relay closes, so that the negative terminal of this battery is received metering circuit ground, the anode of battery enters A/D converter through impact damper.This moment, other battery and metering circuit still were in isolation, thereby to measuring not influence.

See Fig. 3, single-chip microcomputer is controlled analog switch A1 and A2 simultaneously by control end CA, CB.If the control analog switch is chosen input end I2 simultaneously, then analog switch A1 output terminal OUT1 exports the positive terminal voltage of battery E2, and the output terminal OUT2 output of analog switch A2 then is the negative terminal voltage of E2.If OUT2 is received the ground level of measuring system, OUT1 receives the signal input part of measuring system, and measurement result promptly is the value of battery E2 so.Like this, single-chip microcomputer just can be finished measurement to the terminal voltage of E1～E4 by control CA and CB.

The system software of this device adopts modular design, is made up of the plurality of sub program block of assembly language programming.Comprising master routine, data acquisition and processing subroutine transfinite and judge and the warning subroutine man-machine conversation and print subroutine, Interrupt Process subroutine etc.

System's master routine is used to finish the self check and the initialization of instrument.Self check comprises the self check of RAM workspace, A/D converter and analog sampling passage, serial ports and printer etc.Initialization will be set the instrument original state, comprise the setting of timer and serial ports and distribution, the opening of interrupt system, startup of house dog etc.The decline of master routine is that execution command is so that it enters idle condition.This device monitor to as if accumulator, except in the charging of battery and discharge process, needing they are monitored in real time, be under other situation every certain time interval and measure once.Therefore, the metering system of this device is divided into manual control, remote control and regularly three kinds.Any interruption by opening can both wake single-chip microcomputer up, and the external interrupt 0 of this instrument is used to respond keyboard signal, and external interrupt 1 is used to respond the pulse per second (PPS) timing signal that clock chip MC146818 produces, and the interruption of serial port then responds the instruction of host computer.Obviously, these three kinds of metering systems can stop the dormancy of single-chip microcomputer and it is exitted from idle status.Manually control is that " measurement " key that operating personnel pass through on the operating instrument panel makes instrument response interrupt 0.And the timing signal of timing controlled by calendar clock chip makes instrument response interrupt 1.Remote signal is that host computer sends measuring-signal by serial ports RS232 or 485, so that the instrument response serial ports interrupts.

The data acquisition subroutine is used for finishing to be measured and handles battery voltage.The result who is about to the A/D converter conversion is read in single-chip microcomputer and obtain battery voltage value after computing.Calling the judgement subroutine that transfinites then and carrying out out-of-limit judgement, and after adding sign, depositing active data area in.Because this instrument can be stored 30 days historical data, the data that all need to deposit in the earliest in the historical data district after therefore each the measurement shift out the data field, simultaneously current data are deposited in the historical data district.So after measuring end, also will carry out the renewal in historical data district.
