Embodiment Construction

[0033] In order to more clearly and clearly describe the technical solution and purpose of the present invention, the present invention will be further described in detail below. The specific implementation methods described here are only used to explain the present invention, not to limit the present invention.

[0034] As we all know, due to the insulating effect of air, there is a "ground capacitance" between any conductor and the earth, and its size mainly depends on the ground area of ​​the conductor and the distance to the ground. The ground distance is inversely proportional. Due to the insulation effect of the tires of the tank car, both the tank body and the parts of the tank car have the above-mentioned "ground capacitance" with the earth. The area of ​​the tank body to the ground is much larger than that of tank car parts, so the ground capacitance of the tank body is also much larger than that of tank car parts such as valves and pipelines. According to literatur...

Abstract

The invention discloses a tanker grounding detection system and method. The system comprises a tanker receiving connector connected with a tanker part and a grounding connector connected with a grounding body; an on-off switch connected with the vehicle receiving connector and the grounding connector; a detection module and a change-over switch arranged between the vehicle connecting connector andthe grounding connector in series; and a central processing unit connected with the detection module. The detection module comprises a resistance detection unit and a capacitance detection unit whichare connected in parallel; the central processing unit is used for forming a resistance detection circuit and a capacitance detection circuit together with the change-over switch, the on-off switch,the resistance detection unit and the capacitance detection unit; and determining whether the tank car is effectively grounded or not according to dual detection of the on-resistance and the ground capacitance. According to the invention, the phenomenon of false connection can be avoided, and effective grounding of a tank truck is ensured.

Description

technical field [0001] The invention relates to the technical field of grounding, in particular to a tank truck grounding detection system and method. Background technique [0002] The process of loading and unloading flammable and explosive products will generate a lot of static electricity. Once the static electricity accumulates, it will easily cause combustion or even explosion. In order to prevent the hidden danger of electrostatic accidents, it is necessary to equipotentially connect the tanker to the grounding body during the loading and unloading of the tanker to release static electricity, and monitor the grounding status of the tanker in real time. [0003] Existing ground detection systems usually use figure 1 The detection principle of "conduction resistance" shown is to detect the conduction resistance between the grounding body and the tank car, and compare it with the preset resistance threshold. When the on-resistance is lower than the resistance threshold,...
