The technical solution of the utility model is: the under-voltage indicator of a kind of accumulator, contain controller, the sample circuit that resistance R 1 and resistance R 2 form, the input end of described sample circuit is connected with the both positive and negative polarity of accumulator respectively, and, the output of described sample circuit is leaded up to resistance R 3 and is connected with the input pin 2 of described controller, exporting another road is connected with the input pin 3 of described controller, the input pin 8 of described controller is connected with the positive pole of described accumulator, its input pin 5 is connected with the negative pole of described accumulator, is connected with alarm lamp between the output terminal of described controller and the described battery positive voltage; Described controller is ICL8211.
Described alarm lamp is light emitting diode.
The beneficial effects of the utility model are:
1, the utility model is installed on each single storage battery, is provided with luminous door and extinguishes door, just reports to the police when adjusting voltage when the storage battery virtual voltage is lower than, pilot lamp is bright, and the tour personnel can find, confirm separately, do not need to measure one by one, increase work efficiency, reduce labour intensity.
2, the utility model adopts little power consumption control device, and energy consumption is low and measurement is accurate, in addition, adopts sound and light alarm, reminds the maintainer in time to pinpoint the problems and deal with problems.
3, the utility model reasonable in design, implement and high efficiency easily, it is applied widely, is easy to promotion and implementation, has good economic benefit.
Description of drawings:
Fig. 1 is the circuit theory diagrams of the under-voltage indicator of accumulator.
Embodiment:
Embodiment: referring to Fig. 1, among the figure, the under-voltage indicator of accumulator contains controller, wherein: the sample circuit that resistance R 1 and resistance R 2 form, the input end of sample circuit is connected with the both positive and negative polarity of accumulator respectively, and, the output of sample circuit is leaded up to resistance R 3 and is connected with the input pin 2 of controller, exporting another road is connected with the input pin 3 of controller, the input pin 8 of controller is connected with the positive pole of accumulator, its input pin 5 is connected with the negative pole of accumulator, is connected with alarm lamp between the output terminal of controller and the battery positive voltage.
Controller adopts ICL8211, and energy consumption is low and measurement is accurate, and alarm lamp adopts light emitting diode, also can adopt other lamps, determines as required, does not describe in detail one by one.
During use, be provided with luminous door and extinguish door, just report to the police when adjusting voltage when the storage battery virtual voltage is lower than, pilot lamp is bright, and the tour personnel can find, confirm separately, do not need to measure one by one, increase work efficiency, and reduce labour intensity.
