Abstract
The utility model discloses a simple battery-voltage detecting alarm device including an integrated operation amplifier. An input terminal of the integrated operation amplifier is connected with a voltage stabilizing device while the other input terminal of the integrated operation amplifier is connected with a battery to be detected. An output terminal of the integrated operation amplifier is connected with a buzzer alarm. The integrated operation amplifier is connected with a power source module. According to the utility model, a principle of contact alarm is utilized. A certain voltage value is set on one of the input terminals of the integrated operation amplifier by using a voltage stabilizing device, and the other one of the input terminals of the integrated operation amplifier is connected with a positive electrode of the battery to be detected. When the voltage of the battery is lower than that of the preset value, the integrated operation amplifier realizes output control of the buzzer alarm for alarming. In this way, the battery having the voltage lower than the certain preset value is selected and distinguished through a method of buzzer alarming, thereby realizing an aim of judging whether the battery to be detected is qualified or not without observing with eyes. Therefore, the detection speed and the detection quality are improved.
Description
One, technical field:
The utility model relates to a kind of detection alarm device, particularly relates to a kind of simple and easy battery voltage detection warning device.
Two, background technology:
Cell voltage has standard-required, and whether the battery of producing meets standard will be through detecting, and original detection mode is to prop up one by one with omnipotent list to be undertaken by showing to show, and needs observe and can carry out with human eye, and is not only consuming time but also take a lot of work.
Three, utility model content:
Technical problem to be solved in the utility model is: a kind of simple and easy battery voltage detection warning device is provided, and the principle of utilizing the contact to report to the police need not can carry out with observing survey, has improved detection speed and has detected quality.
The utility model is that the technical scheme that the technical solution problem is taked is;
A kind of simple and easy battery voltage detection warning device comprises integrated operational amplifier, and an input end of described integrated operational amplifier connects stable-pressure device, and another input end connects measures battery, and the output terminal of described integrated operational amplifier connects buzzer siren.
Described integrated operational amplifier is connected with power module.
The principle that the utility model utilizes the contact to report to the police, an input end at integrated operational amplifier is set a certain magnitude of voltage with stable-pressure device, another input termination is measured the positive pole of battery, when cell voltage is lower than the voltage of setting value, integrated operational amplifier is reported to the police with regard to output control buzzer siren, so just, the form that the battery that voltage is lower than a certain setting value is reported to the police with buzzing is selected and is distinguished, reach difference and measure whether qualified purpose of battery, need not to carry out with observing survey, improved detection speed and detected quality.
Four, description of drawings:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is principle of work block diagram of the present utility model.
Five, embodiment:
Below in conjunction with accompanying drawing the utility model is further described:
Referring to Fig. 1 and Fig. 2, a kind of simple and easy battery voltage detection warning device, comprise integrated operational amplifier, an input end of this integrated operational amplifier 2 connects stable-pressure device 1, another input end connects the positive pole of measuring battery 3, the output terminal of integrated operational amplifier 2 connects buzzer siren 4, and integrated operational amplifier 2 is connected with power module 5 simultaneously.
The principle that this utility model utilizes the contact to report to the police, an input end at integrated operational amplifier 2 is set a certain magnitude of voltage with stable-pressure device 1, another input termination is measured the positive pole of battery 3, when cell voltage is lower than the voltage of setting value, integrated operational amplifier 2 is reported to the police with regard to output control buzzer siren 4, so just, the form that the battery that voltage is lower than a certain setting value is reported to the police with buzzing is selected and is distinguished, reach difference and measure whether qualified purpose of battery, need not to carry out with observing survey, improved detection speed and detected quality.
