System and method for evaluating safety according to equipment data

Abstract

The invention relates to the technical field of equipment safety, in particular to a system and method for evaluating safety according to equipment data. The method for evaluating the safety assessment according to the equipment data comprises the steps that 1, a database is established, and a normal current curve is formed; 2, a working current curve is monitored; 3, the working current curve iscompared with normal working current, and a low-risk signal of whether or not fire danger exists is judged and sent based on the similarity of the two curves. By establishing the database, the normalcurrent curve style is formed, the working current curve is formed after the working current of the equipment is monitored, and the working current curve is compared with the normal current curve. Based on the similarity judgment of the two curves, the difference degree of the two curves is calculated; when the difference of the two curves is small, it is judged that the equipment is in a normal working state, when the difference of the two curves is large, it is judged that the equipment is in an abnormal working state, and the low-risk signal is sent out. The equipment is repaired after thework on the day is finished.

Description

technical field [0001] The present invention relates to the technical field of equipment security, in particular to a system and method for evaluating security based on equipment data. Background technique [0002] When a switch is used to disconnect the current, if the circuit voltage is not lower than 10-20 volts and the current is not less than 80-100mA, an arc will be generated between the contacts of the electrical appliance. The formation of the arc is that the distance between the contacts is very small and the electric field intensity E is very high (E=U / d). When the electric field strength exceeds 3*10 6 At V / m, the electrons on the surface of the cathode will be pulled out by the electric field force to form free electrons in the contact space. This way of dissociation is called: strong electric field emission. The free electrons emitted from the surface of the cathode and the original few electrons between the contacts accelerate towards the anode under the for...

Problems solved by technology

[0006] However, there are the following problems in the above-mentioned scheme: monitor and judge whether there is a risk of electrical fire on the basis of data such as temperature and gas changes, and when it is judged that there is danger, it is usually that danger has already occurred or is about to occur. At this time, it must be shut down for maintenance immediately. When the time period has to be overhauled, it will affect the production schedule of the product
