Intelligent terminal control system for laboratory safety

Abstract

The invention relates to an intelligent terminal control system for laboratory safety. The terminal system is an intelligent terminal control system which is designed based on an ARM processor and achieves centralized server control and accurate multi-sensor data sampling according to the principle of on-demand service. The control system comprises a main control chip module with ARM-CortexM3 as the core as well as a radio frequency card reading module, a high-precision clock module, a serial communication module, a temperature and humidity module, a liquid crystal display module, a wireless WIFI module, an LED and buzzer module, a storage module, an alternating voltage sampler module and current transformer module and a relay module which are connected with the main control chip module respectively. Compared with the prior art, the system has the advantages that the laboratory management level is intelligently improved and the like.

Description

technical field [0001] The invention relates to the field of embedded technology, in particular to an intelligent terminal control system oriented to laboratory safety. Background technique [0002] The increase in the number of students in the school and the continuous development of the school laboratory have led to an increase in laboratory functions and personnel. Traditional manual management not only has a low level of intelligence and cannot meet the ever-increasing demand, but also has low work efficiency and cumbersome affairs, which leads to potential safety hazards. Laboratory construction and management are an important part of school teaching and scientific research, and safety issues are particularly important for the crowded laboratory environment, and have received more and more attention. Safety accidents that may occur in the laboratory include fire, electric shock and equipment damage. The most prominent problem is fire accidents. The main reasons are (1...

AI Technical Summary

Problems solved by technology

The most prominent problem is fire accidents. The main reasons are (1) forgetting to turn off the power supply, causing equipment or electrical appliances to be powered on for too long, and the temperature is too high, causing fire, such as people leaving for a long time, forgetting to turn off the power supply after a sudden power failure, etc.

(2) Aging of power supply lines, overloaded operation, random pulling of wires to place instruments and equipment, or use of inferior electrical equipment, resulting in circuit failure, such as the expiration date of instruments and equipment has come, but they are still overloaded

(3) Careless operation or improper use has caused the equipment to come into contact with an open flame source, causing the equipment to catch fire

(4) Leakage and electric shock accidents due to violation of operating procedures, random pulling of wires, or faulty defects caused by aging equipment and facilities

(5) For some equipment that requires electric heating, due to power failure, or forgetting to turn off the power after use, the heated medium cannot be restored to its original state according to the original requirements, resulting in safety accidents, etc.

[0006] (1) For the specific monitoring of floors or rooms, the investment cost is high, and specific cables are required for comprehensive transformation and deployment, and a centralized monitoring room needs to be built

[0007] (2) It cannot be subdivided into the power safety detection of a certain device and the function of providing power supply to the device on demand

[0008] (3) For emergencies during the use of experimental equipment, such as electricity safety or sudden fires, special personnel are required to check and turn off the power of some equipment, and the power overload warning of specific equipment cannot be implemented in time, etc.
