Carrier Fault Analyzer and Its Detection Method

technical field

The present invention relates to a fault analysis instrument, in particular to a carrier fault analyzer and its detection method, which is mainly aimed at the analysis of faults occurring when electric power enterprises use the carrier wave method for meter reading, and is applied to the faulty station area of meter reading, belonging to an intelligent substation technology field.

Background technique

Carrier meter reading is unstable in practical applications. There are often missing readings due to unknown reasons in the station area, which affects the collection and testing of collected data. Appropriate instruments can help the on-site staff to analyze the cause of the failure, and the reasons for the failure are summarized as follows: 1. Concentrator carrier carrier meter reading failure; 2. Sub-meter carrier module failure; 3. Power line failure; 4. Message parsing abnormality.

The present invention provides a carrier fault analyzer aiming at the above-mentioned problems in the prior art, which solves the problems in the prior art that it is difficult to judge the fault point and find out the cause of the fault.

Another object of the present invention is to provide a detection method for a carrier fault analyzer.

Technical scheme of the present invention is as follows:

The central processing unit is connected to the current-voltage converter, input controller, carrier communicator, data output device and internal electric energy storage; the current-voltage converter is connected to the carrier communicator; the data output device is connected to the display; the internal electric energy storage is connected to the data memory, internal Flash memory and data communicator; the data memory is connected to the internal Flash memory.

The current-to-voltage converter is connected to an external power collector.

The central processing unit is connected with the auxiliary function unit and the infrared communication unit, and the infrared communication unit is connected with the internal electric energy storage.

The external power taker is connected to an external 3x380v/220v power supply.

The input controller implements input control through an expansion chip.

The present invention starts detection by taking electricity from the main meter to the two ends of the sub-meter on the faulty power line, the analyzer set on the side of the main meter is A, and the analyzer set on the side of the sub-meter is B; its detection method comprises the following steps:

Step 1. Use the B carrier fault analyzer to send a collection command to the sub-meter. If it fails to collect, it means that the sub-meter has a carrier failure; if it returns normally, go to step 2;

Step 2, use A carrier fault analyzer to send a collection command to the sub-meter, if the collection fails, it means that the power signal transmission line is faulty, go to step 3; if it returns normally, go to step 4;

Step 3: Use the A carrier fault analyzer to send a collection command to the sub-meter, and use the B carrier fault analyzer to monitor the carrier signal. If the carrier signal fails to meet the standard, it means that the power line is faulty; if the carrier signal is normal, monitor the message, indicating that the message is abnormal. , indicating a parameter setting failure;

Step 4: Use the A carrier fault analyzer as a virtual submeter, and use the concentrator to collect. If the collection fails, it means that the concentrator has a carrier failure. If the concentrator collects normally, it means that the parameter setting is abnormal.

The advantages and effects of the present invention are as follows:

1. After taking power through the power line, you can manually enter the communication address for carrier meter reading.

2. After taking power through the power line, the strength of the carrier signal transmitted on the power line can be monitored.

3. It can be used as a virtual meter to be read by other carrier meter reading devices.

4. The two analyzing carrier fault analyzers can be used as the main machine and auxiliary machine for each other.

5. It has the auxiliary functions of infrared meter reading, calculator, torch, and event recording, and can adjust the carrier frequency or replace the modules of different communication carrier protocols, and can take power 3x380V/220V on site for work.
