Problems solved by technology
[0003] The main problems of the above-mentioned infrared and ultrasonic dual monitoring probes are as follows: 1. Only the presence and absence of the human body in the monitoring zone can be given, but the distance cannot be given; The Le effect is not obvious, which will cause misjudgment; 3. The Doppler effect needs to continuously transmit and receive ultrasonic waves, which consumes a lot of power; 4. When the ambient temperature is similar to the human body temperature, the detection and sensitivity will drop significantly, sometimes causing failure

Embodiment Construction
[0035] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0036] figure 1, system initialization 1. In actual engineering construction, an emergency communication personnel positioning terminal will be installed at a certain distance in the tunnel. Each terminal has a unique number written in the FLASH ROM, which is the terminal number. Monitoring The platform enters the unique number of the terminal according to the installation of the terminal on the monitored line, so that a one-to-one comparison table between the terminal number and the terminal installation location can be established and maintained in the monitoring center.
[0037] Online human detection 2, after the terminal is initialized, it enters the normal working state, the human body infrared detection probe and the ultrasonic module enter the normal working state, within the ultrasonic and infrared monitoring range, as long as there is a person...

The invention discloses a method for realizing personnel positioning in an electric power tunnel through infrared and ultrasonic double monitoring. The method comprises the following steps of: system initializing; on-line human detecting, wherein the human detection positioning is divided into infrared detection personnel positioning and ultrasonic detection personnel positioning; communication link establishing; terminal information uploading; personnel positioning; and communication link removing. Through the implementation of the method disclosed by the invention, the accurate positioning can be carried out on personnel entering the tunnel; motionless or slowly moving human bodies also can be accurately detected; the relative positions of the human body and a probe can be confirmed; and therefore, when an emergency happens, the quick positioning can be realized and a relevant disposal plan is started. The method is strong in pertinence, comprehensive in positioning measures and high in reliability.
Description
technical field [0001] The invention relates to a personnel positioning method, in particular to a method for realizing personnel positioning through infrared and ultrasonic dual monitoring in a power tunnel. Background technique [0002] At present, the known infrared and ultrasonic dual monitoring probes are composed of infrared sensors, ultrasonic transmitting sensors, ultrasonic receiving sensors and peripheral circuits, wherein the infrared sensors are used to sense the infrared radiation of a specific frequency band emitted by the human body, and the ultrasonic transmitting sensors and receiving sensors use Doppler The Le effect detects the relative motion of the human body and the sensor. The peripheral circuit synthesizes the detection results of infrared rays and ultrasonic waves and outputs the result, that is, when both the infrared probe and the ultrasonic probe show that there is a person, it will report to the monitoring platform that there is a person.
