Abstract
The utility model relates to a battery itinerant detector, which comprises a central controller and a detection circuit, wherein the detection circuit is connected with the detection signal input end of the central controller and comprises an optical coupler which forms a detection loop with a battery to be detected. The temperature compensation signal input end of the detection circuit is connected with a temperature compensation circuit. The battery itinerant detector adopts an optical coupling isolation technology, because the conversion speed of the optical coupler is within several microseconds, the real-time effect of the monitoring can be realized, and the battery itinerant detector adopts a Toshiba nonlinear optical coupler TLP-521 because the cost of the linear optical coupler is too high, so the nonlinear sampling is converted into linear sampling through the internal algorithm of a singlechip and the regulation of a potentiometer, and the precision is ensured to be in a range being +/-0.1V. The battery itinerant detector has the advantages that the control and the detection are realized through the central controller, a plurality of groups of batteries (at most four groups are in one unit) can be conveniently set for simultaneous detection, and the equipment investment can be saved for users.
Description
Technical field
The utility model relates to a kind of battery logging.
Background technology
The battery of being sold is patrolled and examined product in the market, generally adopts miniature relay to patrol and examine the switch of branch road as it and sampled point is selected, and has shortcomings such as mechanical wear, serviceable life is short; Along with development of technology, a lot of equipment are also more and more higher to the requirement of battery maintenance work, and the performance that present relay detection formula battery is patrolled and examined can not satisfy the requirement of a lot of visual plants to battery maintenance and the judgement of powered battery branch road duty far away.
Particularly, traditional fire-fighting emergency power supply accumulator real-time monitoring system mainly is the mode of switching by relay to the monitoring of battery tension, the i.e. relay of each joint accumulator correspondence of adhesive in turn, realization is to the collection of battery tension signal, through sending control chip after the modulate circuit, show the voltage of accumulator by charactron.Sort circuit is simple in structure, and technical being easy to realized, but sort circuit is because prime depends on the switching of relay, and the life-span of electromagnetic relay generally is no more than hundreds of, is about 10ms actuation time, is not suitable for long measurement, the unavoidable maintenance rate that increases product, and real-time is relatively poor.
The utility model content
Technical problem to be solved in the utility model provides a kind of simple in structure, reliability is higher and serviceable life is long battery logging.
For solving the problems of the technologies described above, the utility model provides a kind of battery logging, comprising: central controller, the testing circuit that links to each other with the detection signal input end of this central controller; This testing circuit comprises: be used for constituting the optocoupler that detects the loop with tested battery.
Further, the temperature compensation signal input end of this testing circuit is connected with temperature-compensation circuit.
Further, described optocoupler is linear optical coupling or non-linear optocoupler; Wherein, adopt non-linear optocoupler, be suitable for low hardware cost.
Good effect of the present utility model: (1) battery logging of the present utility model, adopt the light-coupled isolation technology, because the slewing rate of optocoupler is within several microseconds, so can realize the real-time monitored, the cost of linear optical coupling is too high, so this logging adopts the non-linear optocoupler TLP-521 of Toshiba, thereby passes through the adjusting of single-chip microcomputer internal algorithm and potentiometer, this non-linear sample conversion is linear, and guarantee that its degree of accuracy is between ± 0.1V.This battery logging can be set to many Battery packs (maximum 4 groups is a unit) easily and detect the investment that can save equipment for the user simultaneously by central controller controls and detection.(2) battery logging of the present utility model adopts monolithic to detect mainboard and display board is independent, is convenient to install and design.Can organize in parallel the detection more, select (≤4 groups) according to client's needs; Single group of battery series connection joint number at most is 64 joints, satisfies the battery powered demand of fire-fighting emergency power supply; Testing circuit is selected technique for temperature compensation for use; The detection speed of single battery is quick, and batteries sampling required time is about 1mS; Hardware circuit is simple, adopts P521-4 Toshiba light lotus root to detect, and control of PIC series monolithic and video data make hardware circuit seem very simple.
Description of drawings
For the easier quilt of content of the present utility model is clearly understood, below the specific embodiment and in conjunction with the accompanying drawings of basis, the utility model is described in further detail, wherein
Fig. 1 is the structural representation of the battery logging among the embodiment.
Embodiment
See Fig. 1, a kind of battery logging of present embodiment comprises: central controller, the testing circuit that links to each other with the detection signal input end of this central controller, the telecommunication circuit that links to each other with central controller, the warning circuit that links to each other with central controller, the display interface circuit and the accessory power supply that are used to be connected display that link to each other with central controller.
Described testing circuit comprises: be used for constituting the optocoupler that detects the loop with tested battery.
The temperature compensation signal input end of this testing circuit is connected with temperature-compensation circuit.Temperature has bigger influence for the characteristic of digital optocoupler, the forward conduction voltage drop of optocoupler light emitting diode for example, the working point of the phototriode on optocoupler right side.Therefore in wider temperature range, reach high measuring accuracy, just must the influence that temperature variation produces be compensated.
Described optocoupler is linear optical coupling or non-linear optocoupler; Wherein, adopt non-linear optocoupler, be suitable for low hardware cost.Because the slewing rate of optocoupler is within several microseconds, so can realize the real-time monitored.
When adopting non-linear optocoupler, by the adjusting of single-chip microcomputer internal algorithm and potentiometer that this non-linear sample conversion is linear, and guarantee that its degree of accuracy is between ± 0.1V.This battery logging can be set to many Battery packs (maximum 4 groups is a unit) easily and detect the investment that can save equipment for the user simultaneously by central controller controls and detection.
The foregoing description only is for the utility model example clearly is described, and is not to be qualification to embodiment of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here need not also can't give exhaustive to all embodiments.
