A compound intelligent production security system and its security method

Abstract

The invention relates to a composite intelligent production security system and a security method thereof. The composite intelligent production security system is characterized in that: it includes an image sensing terminal for real-time collection of image data around the core dangerous area and processing and analysis; a voice recognition terminal for Real-time collection of voice data around the core dangerous area and processing and analysis; the controller is used to receive the information data collected in real time from the image sensor terminal and voice recognition terminal, to calculate the distance of the personnel relative to the core dangerous area and identify abnormal distress signals, and use to send control instructions to the production equipment; the image sensing terminal and / or voice recognition terminal communicates with the controller through wired and / or wireless means. Based on image sensing and voice recognition composite intelligence, this system solves production security problems, meets flexible layout requirements, can identify and distinguish people and objects, has high positioning accuracy, low probability of false positives and negative negatives, and stable and reliable performance.

Description

technical field [0001] The invention relates to a production protection system, in particular to a composite intelligent production security system and a security method thereof. Background technique [0002] At present, there are two main ways to protect the production area of ​​the factory: one is to set up physical fences to isolate people from the production area, and the other is to use more grating electronic fences. Physical fences refer to setting barriers such as guardrails and cages to prevent personnel from entering the production area. It has the following disadvantages: ①It is inconvenient for staff and materials to enter and leave the production area when the work is stopped. ②The protective boundary cannot be flexibly changed, resulting in space utilization. Low. see figure 1 , the grating electronic fence is an intelligent perimeter system composed of a pulse generator (host) and a physical fence. , time-division detection" way to emit infrared light, once...

Physical fences refer to setting barriers such as guardrails and cages to prevent personnel from entering the production area. It has the following disadvantages: ①It is inconvenient for staff and materials to enter and leave the production area when the work is stopped. ②The protective boundary cannot be flexibly changed, resulting in space utilization. Low

see figure 1 , the grating electronic fence is an intelligent perimeter system composed of a pulse generator (host) and a physical fence. , time-division detection" way to emit infrared light, once people or objects block any adjacent two beams of infrared light emitted by the transmitter for more than 30ms, the receiver will immediately output an alarm signal. This kind of grating electronic fence has high sensitivity; but the grating electronic fence The fence has the following disadvantages: ①The component layout takes up a lot of space, and the installation location is inconvenient; ②The protection area can only be a plane area or a space composed of multiple plane areas, which cannot be flexibly transformed, so that users cannot define arbitrary shapes (such as: Arc-shaped, etc.) production area space; ③ It is easy to be interfered by sunlight and cause false alarms. When the light band reflected or refracted by the ambient light is similar to the band of the grating light source, false alarms and false alarms are prone to occur, and there are certain safety hazards; ④ It is impossible to distinguish between people and objects. The principle of the light barrier is to trigger an alarm when there is occlusion, and the sensitivity cannot be adjusted, so no matter whether it is a person or an object, it will be treated indiscriminately by the system; , regardless of the degree of intrusion, the system will shut down the production equipment uniformly, resulting in a certain impact on normal production
