Abstract
The utility model relates to an accumulator automatic on-line detecting instrument, the structural characteristic of the utility model is that an intelligent connector is connected with a battery charging circuit, the intelligent connector is connected with a single chip computer and is controlled by the single chip computer, the intelligent connector is connected in parallel with a switch, the single chip computer is connected with the detecting port of the battery via a multiple way switch, and a divider and the single chip computer are connected and arranged on an output circuit. Owing to the adoption of the utility model, the whole detection process can be realized under an on-line automatic no power cut condition. Even when the battery faults or damaged, normal electrical power supply with load can not be influence. The utility model has the advantages of small size, light weight, and low cost.
Description
The utility model belongs to the pick-up unit of battery pack working condition.
DC current is all adopted in various device work and control in the places such as transformer station, generating plant, telecommunication bureau.Standby power supply when battery pack commonly used has a power failure as interchange.Exchange U～input as shown in Figure 1 through commutating barostat N multiple-connected battery group Z and load M (referring to the various device electricity consumption of above-mentioned place).This is a kind of DC uninterrupted electric supply installation, powers to the load after battery charging is level and smooth in the constant pressure and flow mode through constant pressure and flow device N when interchange has electricity.Load electricity consumption this moment from alternating current U～, accumulator does not discharge.It is undesired or when having a power failure when extraneous Alternating Current Power Supply to have only, and just gives load by battery pack discharge power supply.If battery-operated is unusual, the power failure in case alternating current meets accident, the regular picture of accumulator impotentia are satisfying the electric needs, and the damage of accumulator will cause above-mentioned place large tracts of land, the long-time power failure, even cause serious consequence such as telecommunications interruption.Therefore detect accumulator and guarantee its reliable and stable work particular importance that seems.Often be fixing several full-time staff for many years, timing wheel flows to each electricity consumption place and goes battery pack is carried out manual detection, pulls off K switch, the extraneous power supply that breaks, and the terminal voltage of each batteries of detection battery pack judges whether battery-operated is normal.When the useless worker of this way is useless, increase the labour expenses; And draw back switch, and stop dispatch from foreign news agency, if accumulator damages, this just makes above-mentioned place have a power failure.The someone adopts as shown in Figure 2 that circuit arrangement detects battery pack now.It regularly opens K by single-chip microcomputer 80C32
1, K closes
2, by single-chip microcomputer, transistor T
1And resistance R
LForm constant current source, single-chip microcomputer saves between accumulator and is connected isolated amplifier G with each, guarantees that the accumulator output current is constant, detects the accumulator voltage fall off rate, relatively judges the battery-operated situation by single-chip microcomputer, sends signals to control center by communication port.Though this scheme makes progress than manual detection, also have problems:
1, as existing fault of accumulator or damage, opens K
1, the dispatch from foreign news agency of having broken, accumulator can not regular picture, will make that various device loses voltage in the workplace, and cause the accident in advance;
2, load device R
LWeigh greatly, isolated amplifier G costs an arm and a leg, thereby device is heavy, and cost is higher.
The utility model is at the shortcoming of prior art, design the device that a kind of automatic on-line detects battery pack, it can timing automatic detect accumulator, even accumulator is bad during detection, can detect the battery-operated situation, also can not make the various device outage, can keep safe and reliable power supply state, advantages of compact and light structure, low production cost.
For achieving the above object with reference to the description of drawings technical scheme:
The drawing explanation:
Fig. 1 is the existing basic circuit diagram of storage battery power supply;
Fig. 2 is the circuit theory diagrams through improved existing detection accumulator plant;
Fig. 3 is the utility model scheme circuit theory diagrams;
Fig. 4 is the utility model full pattern synoptic diagram.
The technical program centre point is to add as shown in Figure 3 intelligent connector to do in the charge in batteries loop Be monolithic processor controlled executive component. Be that single-chip microcomputer connects control high power intelligent connector T2，T
2Get the IGBT of 600V/100A specification, T2With K switch3Parallel connection, single-chip microcomputer through variable connector AD7506 with Batteries detects a mouthful connection, and batteries Z is connected with load M, at load circuit dress current divider F Be connected with single-chip microcomputer 80C32 loop, the specification of current divider F is 100A/75mv.
The course of work of technique scheme:
When needs detect battery pack, open K earlier
3, intelligent connector was in and sought logical power supply state this moment, sent instruction by single-chip microcomputer and made its input voltage that slowly reduces the accumulators group to intelligent connector, the load capacity of the battery pack of single-chip microcomputer monitoring simultaneously.More than 220V or its terminal voltage when not being decreased to 220-10%V, show that battery pack has load capacity as the battery pack terminal voltage with the reduction of input charging voltage.This moment, single-chip microcomputer 80C32 sent instructions to intelligent connector T
2, make it recover conducting, K after 10 seconds
3Auto-closing, whole testing process finished, and recovers extraneous charged state, repeated above-mentioned automatic detection every 8 hours; As open K
3, the single-chip microcomputer 80C32 intelligent connector T that sends instructions
2When slowly reducing input charging voltage, if monitored accumulator battery voltage is when being lower than 220-10%V (showing the battery pack operation irregularity), intelligent connector T
2Meeting conducting at once recovers the Alternating Current Power Supply state.After 10 minutes, enter this trace routine once more automatically at interval, just can confirm that accumulator truly has fault after continuous 5 such detections, send the accumulator failure signal to control center, the maintenance of can dispatching officers by the microcontroller communication mouth.Whole process is all carried out under live state.
Advantage of the present utility model:
1. be to carry out under the on-line automatic no cut-off condition to the whole testing process of accumulator, can any influence do not arranged the load normal power supply;
2. whole device volume is little, in light weight and with low cost.
Claims (2)
1. accumulator automatic on-line detector comprises single-chip microcomputer and switch, it is characterized in that connecing on the charge in batteries loop intelligent connector T
