Laboratory control system

This creation department is about a laboratory image control system, especially a laboratory image control system that can be used for remote image control. The laboratory image control system allows the user to remotely control the equipment in the laboratory via the graphic control method. To reduce the manpower required, improve monitoring efficiency and ensure equipment safety.

The design and manufacture of intelligent environments is one of the most forward-looking technical directions. It is mainly based on science and technology to combine the tools needed in daily life, and to give intelligent tools to the tools needed in the living environment. In the everyday environment, whether in a substantive or abstract environment, human beings are more convenient in performing events.

In general chemical laboratories, it is basically necessary to monitor the three major indicators such as toxic gas, temperature and smoke density to maintain the safety of the laboratory. However, in the current laboratory monitoring equipment, these three indicators are not integrated. A set of monitoring system makes the monitoring process of the laboratory separately monitored, so it takes a lot of human resources. In addition, most of the monitoring systems in the laboratory currently use the values generated by the sensors to make human judgments. Judging by this judgment, it is easy to have a misalignment situation.

In addition, in the laboratory chemical experiments, the most common are toxic gases or liquids, and these toxic gases or liquids will have a major impact on humans, so in the chemical experiments are carried out in the fume hood, so in the fume hood The design is even more important.

This design reduces the speed at which the transparent sliding door falls through the chute, and uses the combination of the chain and the gear to increase the warning effect of the chain breakage to prevent the user from being crushed by the transparent sliding door.

However, in the prior art, when the sliding door is pulled up, the user also needs to pull the sliding door by hand. If the user holds chemical liquid or gas in the hands, the sliding door cannot be operated, and the sliding is affected. Work efficiency, and some users use the finger in their hands to pull up the door for the sake of convenience.
