Abstract

The utility model provides an uninterrupted power supply used in a surveillance camera. The uninterrupted power supply aiming at the application of the surveillance camera mainly comprises a charging panel with the effect of charging, an outage perceptron used for detecting the outage situation of commercial power, a low voltage perceptron used for detecting the inadequate voltage situation of the commercial power, a 12V battery jar for providing standby power at any moment and a regulator for providing a stable voltage output; with the components, if the commercial power is suddenly interrupted or encounters low voltage when the surveillance camera is normally operated, the power source of the surveillance camera can be automatically replaced by the supply of the 12 V battery jar in the uninterrupted power supply so as to achieve the effect of maintaining normal operation and prevent that the surveillance camera can not be operated normally because of a temporary interruption of an external commercial power, which leads to loss of personnel or property.

Description

Be used for the power supply unit that monitoring camera does not cut off the power supply

Technical field

The utility model relates to a kind of improved structure of power supply unit, be particularly related to be the unexpected temporary interruption of a kind of outside civil power when the supply monitoring camera time, can directly supply with inner stand-by power supply, to keep the uninterruptible power supply provider that is used in monitoring camera of normal operation benefit.

Background technology

Press, the use of monitoring camera is quite general in life, no matter in indoor, outdoor or most particular places, all can see its trace, have now or existing monitoring camera, on enforcement is used, mostly be and continue mutually, as shown in Figure 1 with outside civil power by a transformer, so provide the interchange AC of 110V or 220V to convert direct current DC12V to outside civil power, resupply monitoring camera and use; Only described monitoring camera is when reality is used, in case meeting with outside mains failure interrupts, or destroyed by outside manpower, or suffer natural disaster and have a power failure as irresistible factor such as earthquake, typhoon, cause to continue power supply, cause the monitoring camera can't normal operation, cause personnel or damage to property, especially after incident takes place, described monitoring camera just can't operate in the time of can't finding out the main cause of really impelling personnel or damage to property because of breaking, having a power failure, the effectiveness of described monitoring camera is just had a greatly reduced quality, and also loses the meaning of installing.

In addition, commercially available now power supply unit is AC/DC/AC, and still non-transformer supply dealer develops relevant uninterruptible power supply provider AC/DC12V.

For this reason; this case utility model design artificially in response to monitoring camera market and other related application at direct current DC12V product with the above-mentioned article of protection and keep and can not cut off the power supply; be active development research; satisfy the utility model that this practicality is arranged eventually and " be used in the monitoring camera uninterruptible power supply provider " and produce, the phase masses that can benefit the society.

Summary of the invention

The purpose of this utility model is, provides a kind of innovation and the practical uninterruptible power supply provider that is used in monitoring camera, in order to overcome above-mentioned defective.

For reaching this purpose, described uninterruptible power supply provider includes on forming:

One charging panel possesses charging effectiveness is arranged, and it is done with outside civil power earlier and is electrically connected, and is connected with the power failure perceptron with internal voltage regulator again;

One power failure perceptron, in order to the outage situation of induction detecting civil power, it is connected with charging panel earlier, is connected with the low-voltage perceptron again;

One low-voltage perceptron is used in the not enough situation of induction detecting line voltage, and it is connected with the power failure perceptron earlier, is connected with the 12V storage battery again;

One 12V storage battery provides stand-by power supply at any time, and it is connected with the low-voltage perceptron earlier, is connected with pressurizer again; With

One pressurizer provides stable voltage output, and it is connected with the 12V storage battery with the charge inside plate earlier, is connected with the exterior monitoring video camera again;

The beneficial effects of the utility model are compared with the prior art, when reality is used, described uninterruptible power supply provider done with outside civil power with monitoring camera respectively be electrically connected, so when monitoring camera meets with civil power interruption suddenly or brownout during in normal operation, its power source will change automatically by the 12V storage battery supply in the uninterruptible power supply provider, just can continue to keep normal operation.

Embodiment

Below in conjunction with accompanying drawing, to this novel above-mentionedly is described in more detail with other technical characterictic and advantage.

Seeing also shown in Figure 2ly, is that the circuit structure that discloses the utility model one preferred embodiment is implemented schematic diagram.Uninterruptible power supply provider power supply (1) wherein is to establish to have to comprise:

One charging panel (11) possesses charging effectiveness is arranged, and it is done with outside civil power (2) earlier and is electrically connected, and is connected with power failure perceptron (12) with internal voltage regulator (15) again;

One power failure perceptron (12), in order to the outage situation of the outside civil power (2) of induction detecting, it is connected with charging panel (11) earlier, links to each other with low-voltage perceptron (13) again;

One low-voltage perceptron (13) is used in outside civil power (2) the undertension situation of induction detecting, and it is connected with power failure perceptron (12) earlier, is connected with 12V storage battery (14) again;

One 12V storage battery (14) provides stand-by power supply at any time, and it is connected with low-voltage perceptron (13) earlier, is connected with pressurizer (15) again;

One pressurizer (15), stable voltage output is provided, with internal 12V storage battery (14) and external monitoring camera (3) the associated safety protection is arranged all, it is connected with 12V storage battery (14) with charge inside plate (11) earlier, is connected with exterior monitoring video camera (3) again;

Electrical connection by above unit is to constitute the complete uninterruptible power supply provider that is used in monitoring camera (1) of the utility model.

Please consult second in the lump again, shown in three figure, on reality is used, uninterruptible power supply provider (1) is done electrically connect with civil power (2) and monitoring camera (3) respectively, making monitoring camera (3) is to keep its power supply source with civil power (2) when general normal operation, when civil power (2) brownout or electric power interrupt suddenly, power failure perceptron (12) in uninterruptible power supply provider (1) or low-voltage perceptron (13) induction detecting back start running automatically, fast reaction makes stand-by power supply 12V storage battery (14) continue the required power source of supply monitoring camera (3) normal operation, and avoided stopping because of monitoring camera (3), institute causes personnel; temporarily the loss of property.
