Description

Technical Field

[0001] The present invention relates to the technical field of fences, and in particular to a visual intelligent anti-electric shock safety protection electronic fence system. Background Art

[0002] Fence is a kind of railing that surrounds and blocks the surroundings. It has the functions of separation, blocking and shielding. There are many theories about its origin. One theory is that it evolved from screens more than 3,000 years ago. Its functions have also evolved from the original windproof, partition and concealment to barrier and safety protection. During substation construction, arranging safety fences is one of the important safety measures on site. By arranging temporary fences at the work site, the workers can be effectively restricted to the designated work site, preventing the workers from mistakenly entering other energized areas, and avoiding personal electric shock accidents. However, the existing anti-electric shock safety warning products are all warning-type auxiliary safety devices, which can only play an objective warning role, cannot actively protect, and are easily affected by environmental conditions, and the protection effect is limited. Therefore, the present invention proposes a visual intelligent anti-electric shock safety protection electronic fence system to solve the problems existing in the prior art. Summary of the invention

[0003] In response to the above problems, the present invention proposes a visualized intelligent anti-electric shock safety protection electronic fence system. The visualized intelligent anti-electric shock safety protection electronic fence system actively protects non-working personnel to prevent accidents, and displays the current status data of the intelligent safety fence on the main control device. It has great advantages in active protection, visualization, detection accuracy and reliability.

When a person who has not been fingerprint-authenticated passes through the infrared grating, the single-chip computer system triggers the voice announcer and transmits the abnormal personnel warning data to the main control device through the communication system. The main control device includes a control panel and a configuration touch component arranged inside the control panel, and the configuration touch component communicates and accesses the worker trajectory tracking and abnormal personnel warning data of the intelligent safety fence. When there are no workers in the site and other people enter, the power supply of the equipment is immediately cut off.

[0005] A further improvement is that the configured touch component includes a configured touch display screen and a processing core, and the processing core is used to process the operator trajectory tracking and abnormal personnel warning data of the smart safety fence, and send a control signal to the site equipment controller to cut off the power supply of the equipment.

[0006] A further improvement is that the data output end of the processing core is connected to the configuration touch display screen, and the processing core is used to convert the current state data of the intelligent safety fence into a display signal, which is displayed on the configuration touch display screen.

[0007] A further improvement is that the configuration touch component has a built-in embedded configuration system, and the embedded configuration system uses the Modbus protocol as its communication standard and supports RS232 serial port communication compatible with the communication system.

[0008] Further improvements are: the fingerprint module has a built-in database for recording the identity information of the operators. When the operators enter the site, their identities are authenticated through fingerprint recognition and analysis by the single-chip computer system. After the operators complete the work and leave the site, their trajectories are recorded through fingerprint recognition and analysis by the single-chip computer system, so as to conduct subsequent trajectory tracking.

[0009] A further improvement is that the intelligent safety fence and the configuration touch component are powered by 24V, and the fingerprint module, the single-chip computer system, the communication system and the voice announcer are powered by 5V.

[0010] A further improvement is that a support frame is provided below the control panel, and a base is provided at the bottom of the support frame, and a counterweight is provided on the base.

[0011] A further improvement is that the intelligent safety fence includes a sleeve and a fence post, the fence post is movably sleeved on the outside of the sleeve, and the sleeve and the fence post are both square posts.

[0012] A further improvement is that a motor is provided at the bottom of the sleeve, and a screw rod is provided at the output end of the motor, and a nut tube is provided inside the fence post, and the nut tube is inserted into the sleeve and adapted to the screw rod thread.

[0013] A further improvement is that a fence chassis is provided at the bottom of the sleeve, and fixing bolts are provided on the fence chassis, and the fence chassis is fixed to the ground by the fixing bolts.

[0014] The beneficial effects of the present invention are: 1. The present invention is characterized by active protection and has an identity recognition function. It can record the information of the operators entering the site through fingerprint information, which is convenient for later trajectory tracking and the implementation of safety responsibilities. It has an intelligent power-off protection function.
