Problems solved by technology

[0003] However, because the multi-functional power meter has many measurement functions and high technical content, it brings difficulties in testing and maintenance. Every time the tester needs to set the standard output value of the standard signal source during factory commissioning, on the other hand All aspects of manual operation on the multi-function power meter panel, many steps, error-prone, low efficiency, not suitable for large-scale batch production, and cannot guarantee the quality of multi-function power meter shipments

Embodiment Construction

[0028] The present invention connects the RS232 to RS485 converter externally through the two COM communication ports of the upper computer 1, communicates with the standard signal source 2 and the multi-function electric meter 3 respectively, and controls the standard signal source 2 to automatically send out the standard output by the compiled monitoring software signal, and then transmit the measurement value of the power meter back to the monitoring software through the communication interface of the multi-function power meter 3, and the monitoring software analyzes and compares the received measurement value, and automatically judges whether the test meter is qualified or not, thereby greatly reducing the The work intensity of the operator reduces the error rate of the operator in the test, improves the production efficiency, and ensures the quality of the product.

[0029] The standard signal source 2 used in the present invention is the XL803 standard signal source produ...

Abstract

The invention discloses an automatic detection method of a multifunctional electric meter, which is characterized in that the multifunctional electric meter and a standard signal source are respectively connected with an upper computer, and the multifunction electric meter is detected by using detection software per se. By using the method, the invention has the advantages of improving the production efficiency and the outgoing quality of multifunctional electric meters, realizing automatic detection, lowering the production cost because the software has lower hardware requirement to the upper computer, and shortening the detection time and greatly improving the detection accuracy.

Description

technical field [0001] The invention relates to the field of multifunctional electric meters, in particular to an automatic detection method for the multifunctional electric meters. Background technique [0002] With the continuous increase of my country's modernization process, which promotes the rapid development of the power industry, the demand for multi-functional power meters in the power industry is also increasing. At present, the multifunctional power meters on the market have the advantages of multiple measurement functions, high measurement accuracy, fast response and convenient parameter setting, and they are all equipped with communication interfaces. The on-site data acquisition network can be conveniently formed through the communication interface, and the on-site collected data can be remotely transmitted to the monitoring computer in the main control room for centralized control and display. The production dispatcher can grasp the on-site data and control th...
