Abstract

The utility model discloses a sensing clip for jointly acquiring temperature and voltage of a tandem lead-acid storage battery. The temperature sensing clip comprises an outer shell, a temperature conduction silica gel and an electric conduction clip, and is used for the cathode of a battery, that is, one sensing clip is clipped on the cathode of the battery one temperature sensor is arranged in each sensing clip so that the shell of the temperature sensor is integrated with the sensing clip; the portion having a temperature probe on the temperature sensor is arranged in the sensing clip, and then is connected with a singlechip through three wires; and eventually the temperature of the cathode of the storage battery and the battery voltage are transmitted to a monitoring host machine. The sensing clip for jointly acquiring temperature and voltage of a tandem lead-acid storage battery has the advantages of being simple in wiring, being novel and easy to fix, being difficult to drop, being small in volume, being good in test performance, being convenient for maintenance of the storage battery, and being able to be widely applied to the electric power and telecom industries to acquire and monitor the temperature and voltage of the storage battery in a power room.

Description

A kind of series connection lead-acid accumulator temperature voltage is united collection sensing folder

Technical field

The utility model technology relates to a kind of battery tester technical field, is specifically related to a kind of series connection lead-acid accumulator temperature voltage and unites collection sensing folder.

Background technology

In communication system, the working temperature of accumulator and voltage are carried out real-time detection have practical significance.According to " temperature compensation of volume test " among the IEEE1188 annex C, the measured initial medial temperature Tinit of negative pole is different from standard temperature Tstd.Known a kind of accumulator surface temperature measurement is used sensor, and temperature sensor is pasted the surface at battery, and the thermometric degree is drawn three lines; Survey voltage and draw single line; Totally four lines link to each other with single-chip microcomputer, and can only measure the accumulator meter surface temperature, and wiring is many; Be prone to come off, and can be because the many hidden danger that stay to the safety of machine room of wiring.And this accumulator detected temperatures can not satisfy the high-precision measurement requirement of battery terminal negative temperature.Therefore we have developed a kind of series connection lead-acid accumulator temperature voltage and unite and gather the sensing folder; Sensing is clipped on the negative pole of battery, and the position that contains the temperature sensor of temp probe is positioned at the sensing folder, is used for measuring the voltage and the negative pole temperature of accumulator; On the basis of wiring, lacked one than original sensor; Solved original battery tester many shortcomings that when thermometric degree and voltage, connects up, and can not satisfy the high-precision measurement requirement of battery terminal negative temperature, be prone to come off; Complex structure carries defective and deficiencies such as inconvenience.

Summary of the invention

The utility model technical matters to be solved is to above-mentioned deficiency of the prior art; The technical scheme that adopts is: series connection lead-acid accumulator temperature voltage is united collection sensing folder; It is characterized in that: comprise TEMP clamping piece (4), TEMP clamping piece (4) is used for GND, promptly carries a clip (4-1) secretly at GND; The inner temperature sensor (4-2) of placing of sensing folder; The shell and the sensing folder that are temperature sensor are combined as a whole, and the position that contains the temperature sensor of temp probe is positioned at the sensing folder, and the back is through three lines; Being respectively power lead (4-4), data line (4-5), ground wire (4-6) links to each other with single-chip microcomputer (5); Battery terminal negative temperature and voltage send to main frame the most at last, and the unnecessary line of cloth again when surveying cell voltage and temperature has solved the problem many, that there is potential safety hazard in machine room that connected up in the former technology like this.

Technique scheme can find out that the utility model compared with prior art has advantage:

1. simple in structure, reasonable in design and wiring is few, circuit design is simple, has reduced machine room because of a large amount of wiring and cause the probability of unsafe factor.

2. dependable performance and detect effectively adopts the mode of TEMP folder, can measure the voltage of battery terminal negative temperature and battery more accurately.

3. the sensor in the sensing folder can be attached on the negative terminal because the spring force effect is arranged more closely, and thermometric is more accurate.

4. because the negative terminal installing space is limited, use the sensing folder of integrated temperature, voltage detecting, can practice thrift installing space.

In sum, the utility model can solve effectively that existing accumulator detector is narrow to the applicable surface of temperature and voltage detecting, the wiring complicacy, carry defective and deficiency such as inconvenience.

Through accompanying drawing and embodiment, the technical scheme of the utility model is done further detailed description.
