Description

A kind of uninterrupted power supply electronic monitor with anti-theft

technical field

The utility model relates to the field of electronic monitors.

Background technique

Electronic monitors are installed in public places such as intersections, banks, and living quarters, which effectively prevent various theft cases and ensure the safety of people's lives and property. They are indispensable electronic devices in today's society. However, the existing electronic monitors are powered by 220V mains electricity. Once the power supply is cut off or destroyed by human beings, the electronic monitors will not work normally, and the monitoring ability will be lost. and property safety cannot be guaranteed.

Utility model content

The technical problem to be solved by the utility model is to provide an electronic monitor with anti-theft uninterrupted power supply, which can continue to supply power to the electronic monitor in the case of power failure, ensure the normal operation of the electronic monitor, and improve the monitoring range of the electronic monitor personal and property safety.

In order to solve the above technical problems, the technical solution adopted by the utility model is: an electronic monitor with anti-theft uninterrupted power supply, including an electronic monitor, and the electronic monitor is powered by 220V alternating current, which is characterized in that it is also included in A lithium rechargeable battery power supply circuit capable of supplying power to the electronic monitor in the event of a power failure, the lithium rechargeable battery power supply circuit includes a charging circuit, a timing switch, a lithium rechargeable battery and an inverter;

The 220V alternating current is converted into direct current through the charging circuit and output to charge the lithium rechargeable battery;

The timing switch is connected between the charging circuit and the lithium rechargeable battery for timing, opening and closing the circuit;

The direct current of the lithium rechargeable battery is converted into 220V alternating current through an inverter to supply power for the electronic monitor.

In a further technical solution, a password lock is provided at the battery port where the battery is taken and placed on the monitor casing.

The beneficial effects produced by adopting the above-mentioned technical scheme are: a timing switch is provided, and when the power is not cut off, the rechargeable lithium battery is charged regularly; It can work normally under the electronic monitor to ensure the safety of personal and property within the monitoring range of the electronic monitor; it is equipped with a combination lock to prevent others from deliberately taking out the battery when the power is cut off, and to improve the anti-theft ability of the electronic monitor.

Fig. 2 is a structural diagram of the utility model.

In the accompanying drawings: 1. battery port, 2. lithium rechargeable battery, 3. timer switch, 4. password lock, 5. control circuit board.

Detailed ways

Below in conjunction with accompanying drawing and specific embodiment, the utility model is described in further detail.

As shown in Figure 1, a kind of uninterruptible power supply electronic monitor with anti-theft, comprises electronic monitor, and described electronic monitor adopts 220V AC power supply, is characterized in that it also includes the ability to power the electronic monitor in the case of power failure. The lithium rechargeable battery power supply circuit powered by the monitor, the lithium rechargeable battery power supply circuit includes a charging circuit, a timing switch, a lithium rechargeable battery and an inverter; the 220V alternating current is converted into a direct current output to the lithium rechargeable battery through the charging circuit Charging; the timing switch is connected between the charging circuit and the lithium rechargeable battery for timing, opening and closing the circuit; the direct current of the lithium rechargeable battery is converted into 220V alternating current through an inverter to supply power for the electronic monitor. As shown in Figure 2, the spherical electronic monitor, the lithium rechargeable battery 2 and the timing switch 3 are located on the wall pole of the electronic monitor, and the battery port 1 where the battery is taken and placed on the monitor shell is provided with a password lock 4, and the control circuit A charging circuit, an inverter and a monitoring circuit are integrated on the board 5 .

When the power supply can work normally and there is no man-made damage, the electronic monitor is powered by 220V mains and works normally. After 48 hours, the timing switch is closed, and the charging circuit charges the lithium rechargeable battery. After 1 hour, the timing switch is disconnected. ; After 48 hours, the timer switch is closed to charge the lithium rechargeable battery for 1 hour, and the timer switch is turned off again, and this cycle is used to charge the lithium rechargeable battery. Once the 220V power supply is damaged and cannot supply power to the electronic monitor, the lithium rechargeable battery will continue to supply power to the electronic monitor through the inverter, so as to realize the uninterrupted power supply of the electronic monitor and ensure that the electronic monitor can be powered in case of power failure. Normal work, improve the anti-theft ability of the electronic monitor, and avoid personal and property damage.

On the shell of the electronic monitor, a combination lock is provided at the battery port where the battery is taken and placed, to prevent the lithium rechargeable battery from being deliberately taken out when the power is cut off, and the electronic monitor works normally, improving the anti-theft monitoring capability of the electronic monitor. the
