Embodiment Construction

[0036] Such as figure 1 — image 3As shown, a portable intelligent alarm fence includes a pole 1, a processor, an acousto-optic alarm module 11, a camera 12, a distance measuring sensor 15, an access control module 2 and a host computer, and the number of the poles 1 is several, The selection of the specific quantity can be flexibly set according to the size of the fence site according to the needs of the site, and the adjacent two vertical poles 1 are connected by setting the telescopic belt 14. The telescopic belt 14 is arranged inside the vertical pole 1. During use, the vertical pole 1 The inner telescopic belt 14 is completely pulled out, the length of the telescopic belt 14 is used to the maximum value, and the joint of the telescopic belt 14 is engaged in the bayonet 13 of another vertical pole. Take it out from the bayonet socket 13, press the recovery button arranged on the pole 1, the telescopic belt 14 is automatically retracted into the inside of the pole 1, and t...

Abstract

The invention discloses a portable intelligent alarm fence, and belongs to the technical field of a safety protection appliance. The portable intelligent alarm fence comprises a plurality of vertical rods, an entrance guard module and a host computer. Two adjacent vertical rods are connected through arrangement of a telescoping band, the telescoping bands are arranged inside the vertical rods, processors are arranged at lower positions inside the vertical rods, the processors are respectively electrically connected with cameras, acousto-optic alarm modules and distance measuring sensors, the processors communicate with the host computer through a wireless network, and the vertical rods are also internally provided with rechargeable batteries. According to the invention, the ultrasonic distance measuring sensors carry out detection by use of a supersonic wave echo ranging principle according to a Doppler effect of a mobile object, human identification is finished by use of an image processing means, and the problems of sensitivity to ambient temperature in human identification and insensitivity to object barriers in the human detection when infrared sensors are used for detecting specific-wavelength infrared rays emitted by a human body are solved.

Description

technical field [0001] The invention relates to a safety protection appliance, in particular to a portable intelligent alarm fence and a human body approach detection method. Background technique [0002] Public industries such as electric power, telecommunications, gas, and water supply are dangerous places in outdoor maintenance and other work sites. Isolation guardrails need to be set up to prevent miscellaneous personnel from entering by mistake, so as to ensure the safety of personnel and test equipment. The Chinese patent application number 201310680988.6 discloses an intelligent portable safety fence, which is characterized in that: the column is provided with a pyroelectric sensor and an alarm, the pyroelectric sensor is provided with a switch, and the pyroelectric sensor and the alarm Electrically connected, the pyroelectric sensor is used to receive and amplify the infrared radiation generated by the movement of the human body, and drive the alarm to send out an al...
