Problems solved by technology

[0003] Although smart meters have many of the above advantages, there are also daily maintenance and repair problems in actual production applications. Due to their high technical content, the quality requirements for maintenance personnel are also relatively high
Moreover, the factory inspection during mass production is currently mainly manually operated directly on the operation panel of the smart instrument, which is labor-intensive, error-prone, and inefficient, and cannot meet the requirements of large-scale mass production.

Abstract

A method for detecting instrument of intelligent instrument detection unit includes connecting intelligent instrument in series between test desk and computer, reading in measuring data and switching state to computer under communication and interface protocol, comparing measured data with setting data for judging whether measured data is in specified range or not.

Description

technical field [0001] The invention relates to an intelligent instrument detection device, in particular to an instrument detection method in the intelligent instrument detection device. Background technique [0002] With the rapid development of microelectronics technology and the continuous improvement of automation level, various intelligent instruments with built-in microprocessors are being more and more widely used in various fields. These smart instruments not only have the advantages of high measurement accuracy, fast response and convenient parameter setting, but also have communication interfaces. The on-site data acquisition network can be conveniently formed through the communication interface, and the on-site collected data can be transmitted to the monitoring computer in the main control room for centralized control and display. The monitoring computer can grasp the on-site data and control the on-site equipment in time. [0003] Although smart meters have ma...
