An auxiliary device for strong inspection of measuring equipment

Abstract

The invention specifically relates to a metering equipment compulsory inspection auxiliary apparatus which is installed on a power supply male plug of metering equipment to be compulsorily inspected. The apparatus comprises a control box, a control circuit, a female plug and a fastener, wherein the female plug comprises an insulation cover body and a power line, the insulation cover body is arranged at the outer surface of the control box, the insulation cover body is internally provided with a strip-shaped insertion hole with a metal contact sheet, the fastener is arranged in the control box and extends out of the control box to be engaged with the metal contact sheet in the strip-shaped insertion hole, and the metal contact sheet matches a conductive terminal of a male plug of the metering equipment to be compulsorily inspected; one end of the power line is connected with the metal contact sheet, and the other end passes through the control box to be connected with an external power source; the control circuit comprises a processor, a relay, a button battery supplying power to the processor and a clock circuit electrically connected with the processor; and the relay is arranged on a loop where the power line and the external power source are disposed, and the control end of the relay is connected with the processor electrically. Through such a technical scheme, power of metering equipment which is used beyond a compulsory inspection period can be automatically cut off.

Description

technical field [0001] The invention relates to the technical field of forced inspection of measuring equipment, in particular to an auxiliary device for forced inspection of measuring equipment. Background technique [0002] According to the "Management Measures of the People's Republic of China for the Verification of Work Measuring Instruments with Compulsory Verification", units or individuals that use compulsory verification of working measuring instruments must register the compulsory verification of working measuring instruments they use in accordance with the regulations and report to the local county (city) ) level people's government metrology administrative department for the record, and apply for periodic verification to the metrological verification institution designated by it. The periodicity of mandatory verification shall be determined by the metrological verification institution implementing the compulsory verification according to the metrological verifica...

AI Technical Summary

Problems solved by technology

If the verification period has passed and the merchant has not actively submitted an application for compulsory inspection to the metrology department, the equipment that has not been traced to the source of the standard instrument may be unqualified, and its indication value is inaccurate. If the merchant continues to use it, the optometry will not be correct. Accurate, unable to match suitable glasses, thus causing irreparable damage to the eyes of consumers

In my country, not only the glasses industry, but also a large number of measurement and inspection equipment for trade settlement, security protection, medical and health, environmental monitoring and other industries serve the Chinese people every day. Therefore, due to various reasons, various measuring instruments used over the cycle , not only increases the management cost of the supervision department of the strong measurement inspection, but also is not conducive to the orderly development of the strong measurement inspection work. This hidden danger of inaccurate measurement affects fair trade, violates the rights and interests of consumers, and even threatens the people. physical health and social stability
