Thermal imaging based device for supervising and managing operators on duty in standardized mode

Abstract

The invention relates to a thermal imaging based device for supervising and managing operators on duty in a standardized mode. The device comprises an optical system, a thermal sensor, a signal amplifier, a video processing and analyzing module, a camera shooting module, a memory, an identity identification module, a power supply management module, a voice module, a loudspeaker, a storage battery, a single chip machine, a wireless module and a telephone module. The operators on duty are firstly required to perform identity identification (sign-in) before working. After the identity identification, the operators on duty are in a monitor state, and a thermal imaging camera real-timely detects and analyzes whether a human body exists. When the human body can not be detected in a detection zone for a certain time, the optical system sends a voice prompt to require for the identity identification and starts to record a video. If the identity identification passes in the prompting time, the video recording stops, and a message that the operators are on duty is sent out; and if the identity identification fails to pass, the video recording stops, and a message that the operators are not on duty is sent out.

Description

technical field [0001] The invention relates to a thermal imaging technology supervisor on duty and a supervisory device for standardized management, belonging to the field of duty supervision. Background technique [0002] With the rapid development of China's economy and society, new situations and new problems faced by fire protection work are increasing day by day. Fire risks and fire prevention and control difficulties are increasing. The problem of incompatibility between the public's fire safety awareness and the requirements of modern social management is still relatively prominent. The fire safety situation in China is still severe, and it is still in a fire-prone and frequent period on the whole. [0003] In some units, fire safety responsible persons, management personnel and fire control room duty personnel have low fire safety quality. Illegal phenomena such as unattended fire control room or finding someone to replace the duty are common, which often leads to f...

AI Technical Summary

Problems solved by technology

[0014] The infrared or microwave detection technology described in the above patents cannot detect a stationary human body and is easily disturbed by the external environment. The interference of infrared technology is mainly manifested as: 1. It is easy to be interfered by various heat sources and light sources

2. The passive infrared penetration is poor, the infrared radiation of the human body is easily blocked, and it is not easy to be received by the probe

3. Susceptible to interference from radio frequency radiation

4. When the ambient temperature is close to the human body temperature, the detection and sensitivity will drop significantly, sometimes resulting in short-term failure

[0015] If only microwave technology is used in the field of duty to interfere, the main manifestations are falling objects or moving objects such as doors and windows blown by the wind, which will cause false alarms. In addition, the mobile phone communication signal near the detection area and the operation of various electrical appliances in the monitoring area The generated electromagnetic waves will also cause the microwave detector to generate a human signal by mistake, causing the system to give wrong duty supervision information

[0016] If infrared or microwave detection is used but a false alarm occurs (someone is on duty but the movement is small and no one handles it), the on-duty person needs to move to reset and eliminate the alarm; in this way, when the on-duty person is highly concentrated on work, the false alarm It may increase the operation of eliminating the alarm, which will cause the work energy to be unable to concentrate and bring psychological pressure to the staff on duty
