Electric meter production management system

Abstract

An electric meter production management system comprises a plurality of electric meters, a plurality of a data collectors, a database and at least one computer, wherein the data collectors collect the production data generated by the electric meter production, each data collector is provided with an unique communication serial port number, the computer is connected with the data collectors via a serial bus and is connected with the database via a database link, the computer controls the data collectors to collect the production data of electric meters, analyzes the production data sent from the data collectors, refreshes the analyzed data for the database and real-timely displays the information corresponding to the orders. The system can automatically real-timely attain the production data of electric meters, analyze the production data and real-timely displays the information corresponding to the orders, and therefore, users can handle the production state of the whole order, and quickly attain the production data of electric meters when there is complaint to resolve the complaint.

Description

technical field [0001] The invention relates to a production management system, in particular to a production management system of electric meters. Background technique [0002] The ammeter is a precision measuring instrument. In order to ensure its operation quality, the manufacturer needs to conduct a series of parameter tests on it during the production process of the ammeter, such as start-up and creep test, basic error test, calibration constant test, voltage influence test, Frequency impact test, word walking test, etc., so as to obtain qualified meters. [0003] In the production process, the test data generated by each parameter test are generally stored independently in their respective parameter test devices. Therefore, the test data in the production process cannot be shared and managed uniformly, which is not conducive to the statistical analysis of the production test data and subsequent management operations. For example, in the production process, it is impo...

Therefore, the test data in the production process cannot be shared and managed uniformly, which is not conducive to the statistical analysis of production test data and subsequent management operations

For example, in the production process, it is impossible to know the number of electric meters in each process, the completed quantity, and the online defective rate in real time.

When a customer complains about a problem in the process of using the meter, the production process information (for example, test data) of the problematic meter cannot be traced back, and it is impossible to understand the specific problems in the production process and the corresponding reasons, solutions and other data
