Description

The accumulator detector

Technical field

The utility model relates to a kind of instrument that is used to test the electrical conditions of accumulator or battery, particularly a kind of accumulator detector.

Background technology

Accumulator is a kind of important standby power supply, owing to it seldom uses, but need seem very important again during use, so also just extremely important to the regular detection of accumulator.In the prior art, in fact the accumulator detector that conventional sense is used is a kind of voltage-measuring equipment, only the voltage of accumulator is measured, the parameter that detects is too single, can not embody the performance index of accumulator, cause erroneous judgement disconnected and cause accident to take place easily, secondly the existing storage battery detector is not to be with communication device, therefore its data can't directly be transferred to host computer, need read from the accumulator detector by detection person, import host computer then, cumbersome in the operation, and the manual read fetches data and also has subjectivity, occurs error easily.

Invention constitutes

The accumulator detector that provides a kind of detected parameters can demonstrate fully the accumulator property index according to the deficiencies in the prior art part is provided the purpose of this utility model.

The utility model is realized by following approach:

The accumulator detector, include voltage measuring apparatus, its structural feature is, also include a kind of central processing unit, temperature sensor and data output device, the signal output part of voltage measuring apparatus, the signal output part of temperature sensor are electrically connected with two signal receiving ends of central processing unit respectively, and an output terminal of central processing unit is electrically connected with data output device.

For accumulator, except voltage, temperature is its most important index, and when the temperature anomaly of accumulator, its capacity and performance also will be unusual, so the combination of temperature index and voltage indexes just can embody the performance index of accumulator more fully.Central processing unit is handled from the voltage data of voltage measuring apparatus with from the temperature data of temperature sensor, handle, then by data output device with the parameter output that records.Central processing unit is a kind of data processing equipment efficiently, and it has automatic error correction function, thereby communication quality is highly stable, and communication speed also greatly improves.

The utility model can further be specially:

Data output device is a kind of communication device, perhaps is a kind of display device.

Data after central processing unit is handled can be exported by display device, are convenient to survey crew and watch, and can also directly be transferred to host computer by communication device, have so just solved the contact problem between the two.Data directly are transferred to host computer after detection, host computer can directly manage data, prevent to read because of personnel the error of generation, simultaneously can also management data.

Voltage measuring apparatus includes a bleeder circuit and an analog to digital conversion circuit, the voltage output end of accumulator is electrically connected with bleeder circuit, the bleeder circuit output terminal is electrically connected with analog to digital conversion circuit, and the output terminal of analog to digital conversion circuit is electrically connected with the signal receiving end of central processing unit.

Bleeder circuit also is a kind of signal acquisition circuit, the simulating signal of its collection, and analog to digital conversion circuit becomes digital signal to send central processing unit to this analog signal conversion to handle.

Also include storer, the receiving end of this storer is connected with the central processing unit transmission.

Storer is used to store the data that accumulator is measured, and the supplemental characteristic that so just can be management of battery provides the basis and ensures that the basic data for host computer provides backup simultaneously.

The utility model can also further be specially:

Central processing unit is that a kind of model is the single-chip microcomputer of STC12C5410AD.

Central processing unit can adopt single-chip microcomputer, the processor that can also adopt data processing chip and support circuit thereof to form, and optimal selection is a single-chip microcomputer, and is all relative much simple with modification in maintenance.

It is the AD chip of DS2438 that analog to digital conversion circuit adopts a kind of model.

Analog to digital conversion circuit is a kind of commercially available conventional products, and its model can be selected as required.

It is the sensor of DS18B20 that temperature sensor adopts model.

Temperature sensor also is a kind of product of maturation, preferably selects the temperature sensor of fineness two decimal places for use at the utility model.

In sum, the utility model provides a kind of accumulator detector, at first on the basis of voltage measuring apparatus, increased temperature sensor, not only can the measuring voltage value, can also measure the surface temperature value of accumulator, the further perfect performance index of measuring battery play an important role to the maintenance of accumulator; Secondly, owing to adopt central processing unit, can select communication output, thereby realize and the direct communication of host computer, solve staff's complex operation problem, stop to misread several situations substantially.

Specific embodiment

Most preferred embodiment:

With reference to accompanying drawing 1, the accumulator detector, include voltage measuring apparatus, a kind of central processing unit, storer, temperature sensor and data output device, voltage measuring apparatus includes a bleeder circuit and an analog to digital conversion circuit, the voltage output end of accumulator is electrically connected with bleeder circuit, and the bleeder circuit output terminal is electrically connected with analog to digital conversion circuit, and the output terminal of analog to digital conversion circuit is electrically connected with a signal receiving end of central processing unit; The signal output part of temperature sensor is electrically connected with another signal receiving end of central processing unit, and the receiving end of storer is connected with the central processing unit transmission, and an output terminal of central processing unit is electrically connected with data output device.Data output device is a kind of communication device, can be mainly to be made up of the RS485 interface, can also be made up of network interface card.
