High school chemical experiment safety protection system and method

Abstract

The invention discloses a high school chemical experiment safety protection system, comprising a central controller, an address code extraction unit, a school doctor management and control center, a fire alarm unit, and a central Zigbee control device and a plurality of distributed control nodes, which are connected with each other through a Zigbee network, wherein the central controller, the address code extraction unit, the school doctor management and control center, the fire alarm unit and the central Zigbee control device are connected with each other via the Internet; and by means of thecontrol of the node Zigbee control device, a dangerous gas can be extracted in time, the air in a chemical laboratory can be converted, teachers and students are quickly guided to evacuate, and meanwhile the fire department is notified at the first time to effectively control the gas diffusion range. The safety protection system minimizes the injury to the teachers and students, handles the dangerous gas leakage accidents efficiently and quickly, guarantees the safety of the teachers and students and provides a safe learning environment.

Description

technical field [0001] The invention relates to a safety protection system, in particular to a high school chemical experiment safety protection system and method. Background technique [0002] Chemistry is a compulsory course in high school teaching, one of the important basic sciences, and a subject based on experiments. However, the current high school chemistry teaching is still mainly based on book teaching. Teachers help students understand through oral explanations, combined with pictures and text in books, and rarely conduct real chemical experiments. One of the main reasons is that chemical experiments have Certain dangers, conducting real chemical experiments may endanger the personal safety of students. In the current chemical experiments in high school, there are some chemical reactions involving dangerous gases, such as hydrogen, carbon monoxide, nitric oxide, chlorine, etc. These gases are flammable, explosive, and poisoned by inhalation. Teachers and students...

However, the current high school chemistry teaching is still mainly based on book teaching. Teachers help students understand through oral explanations, combined with pictures and text in books, and rarely conduct real chemical experiments. One of the main reasons is that chemical experiments have Certainly dangerous, conducting real chemistry experiments may endanger the personal safety of students

In the current chemical experiments in high school, there are some chemical reactions involving dangerous gases, such as hydrogen, carbon monoxide, nitric oxide, chlorine, etc. These gases are flammable, explosive, and poisoned by inhalation. Teachers and students If there is a large number of people, if there is a dangerous gas leak, it is necessary to remove the dangerous gas in a timely and effective manner and carry out evacuation and rescue work in a timely manner. In addition, the gas diffuses quickly, so it is necessary to notify the fire department in time, so as to quickly control the dangerous area
