Detailed ways

As shown in Figure 1, the wireless anti-theft alarm system of the human body microwave induction automatic camera power transformer of the present invention includes an anti-theft alarm transmitting part and an anti-theft alarm receiving part, which are controlled by wireless signals. The anti-theft alarm transmission part mainly includes the human body microwave induction controller, the host monitoring controller, the infrared night vision digital storage camera, the storage device and the transmission and reception module. The anti-theft alarm receiving part mainly includes a transmitting and receiving module, a host alarm controller, a terminal computer and an alarm horn. Both the transmitting part and the receiving part are respectively provided with a main power supply module and a backup power supply module. The backup power supply is to ensure that each functional module can still work normally in the event of a power failure. The main power supply module steps down the external 220V alternating current to 12-20V direct current through a transformer to charge the standby power supply module. The backup power supply module adopts a 7.4V lithium battery pack, and the charged lithium battery pack provides working voltage to each functional module. The storage device can adopt mobile storage devices such as SD card and USB flash drive.

The difference from the existing technology is that the human body microwave induction controller can be used for small-scale on-site anti-theft control of objects. It is a low-power microwave controller with a working frequency of 3.8-4Ghz. The working frequency of the microwave controller is 9-25Ghz, and the preferred center frequency is 10.525GHz. This frequency has a large control range and strong penetrating ability. It is suitable for anti-theft control in a relatively large indoor range, and is not suitable for outdoor working environments. Otherwise, it will be windy, Rain, swaying vegetation can cause false alarms.

The working principle of the utility model is: when someone passes through the anti-theft range of the power transformer, the human body microwave induction controller of the anti-theft alarm emitting part will sense the person, and trigger the host monitoring controller to work. The host monitoring controller controls the infrared night vision digital storage camera to take pictures or video, and the image data is stored in the storage device, or the image data is sent to the monitoring center through the transmitting and receiving module. If a power outage is detected at this time, the host monitoring controller will control the transmitting and receiving module to send an alarm signal. After the transmitting and receiving module of the anti-theft alarm receiving part receives the alarm signal, the alarm signal is input to the host alarm controller. The host alarm controller controls the alarm horn to make a sound to notify the guardians, and at the same time, the alarm data can be sent to the terminal computer.

The anti-theft system of the utility model can monitor a plurality of power transformers, and can also alarm a plurality of monitoring centers; the anti-theft system can include a plurality of anti-theft alarm transmitting parts and a plurality of anti-theft alarm receiving parts. codes to differentiate. And it can be controlled by the remote controller matched with the anti-theft system, which includes arming, disarming and code matching functions. In order to prevent multiple power transformer alarm systems from interfering with each other, each host monitoring/alarm controller integrates an automatic coding system. When the code pairing function of the remote control is started, the remote control will send a coded signal, and the transmitting and receiving module of the anti-theft alarm transmitting part receives the coded signal from the remote control, and the host monitoring controller controls the transmitting and receiving module to send out the coded signal, and the anti-theft alarm The transmitting and receiving module of the receiver receiving part will receive the encoded signal, and the host alarm controller will recognize that this is a power transformer alarm system and complete the code matching function.

When the arming function of the remote controller is started, the transmitting and receiving module of the anti-theft alarm transmitting part receives the arming signal of the remote controller, and the host monitoring controller is connected to functional modules such as the human body microwave induction controller and the infrared night vision digital storage camera.

Correspondingly, when the disarming function of the remote controller is activated, the host monitoring controller disconnects functional modules such as the human body microwave induction controller and the infrared night vision digital storage camera. In this way, maintenance personnel can work without calling the police, and the arming function can be started after the maintenance is completed, so that the alarm system can work normally again.

The host monitoring controller of the utility model also includes an anti-sabotage function. When the host monitoring controller detects that the shells of functional modules such as the human body microwave induction controller and infrared night vision digital storage camera are forcibly destroyed, the host monitoring controller will pass The transmitting and receiving module sends out different alarm signals. The transmitting and receiving module of the receiving part of the anti-theft alarm will receive these signals, and the host alarm controller will recognize that different devices have been damaged, and control the alarm horn to emit different sounds to notify the guards.

The utility model has the advantages of simple structure, easy manufacture, convenient installation and use, low cost and long alarm distance, and is suitable for installation and use on various power transformers far away from villages, and effectively curbs losses caused by man-made theft of power transformers.
