Early equipment overheating warning device Before the temperature reaches the ignition point, there will be an electron escape point, at which the combustible material will release a large number of pyrolytic ions. By measuring the concentration of pyrolyzed ions around the equipment, the specific state of the equipment can be sensed and distinguished in real time to realize advance warning. Compared with other monitoring technologies such as temperature and smoke feeling, the early warning can be issued at least several hours in advance. Very early fire warning can detect signs of burning in advance and protect valuables or precision equipment from damage. In server rooms, financial warehouses, art museums, etc., it can help businesses/institutions avoid RMB millions of property losses.

Physical, chemical and biological experiments The Ministry of Education clearly points out that students' experimental operation and ability performance are included in the comprehensive quality evaluation, and scientific experimental education will soon become a key point of middle school education. However, it is difficult to meet the large demand of invigilators in the examination scheme of physical, chemical and biological experiments. The assistant scoring system for physical, chemical and biological experiments is a modular solution enabled by AI. Its core is to extract key frames from the experimental test video according to the scoring rules and processes, so that teachers only need to re-view the key frames to score. The scheme can help teachers save at least 50% of their scoring time, and the product is expected to be densely put in science experiment education.

Underwater blue light wireless communication system It sees high lase power, good beam quality, long communication distance and strong practicability.
