The system is characterized in that human body infrared detectors and a voice alarm device are also included; the human body infrared detectors are equipped with wireless transmission modules installed within certain ranges of electrical devices of a transformer station; the voice alarm device is installed near the electrical devices; the human body infrared detectors transmit detection information to the wireless reception device in the microprocessing unit through the wireless transmission modules; the microprocessor sends an instruction to the voice alarm device via radio waves; and the data transmission device receives the instruction of the microprocessor and communicates with the monitoring host via radio waves.

Description

Human body short-distance voice reminder security system

technical field

The utility model belongs to the technical field of substation safety protection, in particular to a human body short-distance voice reminder security system.

Background technique

A lot of equipment in the substation is high-risk equipment, which requires professionals to access, maintain, debug, etc. However, occasionally non-professionals may enter the substation, out of curiosity or not knowing the danger of the equipment, they will come into close contact with the equipment. pose a serious safety hazard.

At present, most substation equipment is posted with warning signs, which cannot achieve a good early warning effect.

Contents of the invention

The purpose of the utility model is to solve the problems of the prior art, and provide a human body close-range voice reminder security system.

The technical scheme that the utility model takes for solving the problems of the technologies described above is:

The human body short-range voice reminder security system includes a monitoring host and a micro-processing unit. The micro-processing unit includes a data transmission device and a wireless receiving device. It is characterized in that it also includes a human body infrared detector and a voice alarm device; the human body infrared detector is set There is a wireless transmitting module, which is installed within a certain range around the electrical equipment in the substation; the voice alarm device is installed near the electrical equipment in the substation; the human body infrared detector sends detection information to the wireless receiving device in the micro-processing unit through the wireless transmitting module , the microprocessor sends instructions to the voice alarm device through data lines or radio waves; the data transmission device receives instructions from the microprocessor and communicates with the monitoring host through radio waves.

Compared with the prior art, the utility model has the following beneficial effects:

The utility model adopts a human body infrared detector, which greatly improves the safety factor of the substation, and can effectively prevent unintentional intrusion of non-professionals to cause accidents.

The figure is a structural schematic diagram of the utility model.

In the figure: 1—microprocessor; 2—wireless receiving device; 3—human body infrared controller; 4—personnel; 5—electrical equipment; 6—voice alarm device; 7—data transmission device; 8—monitoring host; 9 - Microprocessing unit.

Detailed ways

As shown in Figure 1, the human body short-range voice reminder security system includes a monitoring host 8 and a micro-processing unit 9, and the micro-processing unit 9 includes a data transmission device 7 and a wireless receiving device 2, and is characterized in that it also includes a human body infrared detector 3 , voice alarm device 6; the human body infrared detector 3 is provided with a wireless transmitting module, which is installed within a certain range around the substation electrical equipment 5; the voice alarm device 6 is installed near the substation electrical equipment 5; the human body infrared detector 3 Send the detection information to the wireless receiving device 2 in the microprocessing unit 9 through the wireless transmitting module, and the microprocessor 1 sends instructions to the voice alarm device 6 through radio waves; the data transmission device 7 receives the instructions of the microprocessor, and Wave communicates with the monitoring host 8.

When the system is in use, the human body infrared detector 3 detects the distance of the person 4 approaching the electrical equipment. When the distance enters the set range, a signal will be triggered, and the signal will be transmitted to the wireless receiving device through radio waves, and then transmitted to the Microprocessor, and then the microprocessor sends an alarm command, which is transmitted to the voice alarm device 6 through wireless or wired electric waves, and the voice alarm device 6 plays the set voice prompt according to the information type, and the data in the whole process is saved. , the data transmission device 7 transmits the data to the monitoring host.
