Description

Technical Field

[0001] The utility model relates to the field of smart meters with carrier message monitoring modules, and particularly to a smart meter with a carrier message monitoring module. Background Art

[0002] At present, the carrier communication method is the main way to read the data of electric meters in the power system. Especially in remote meter reading, it plays an important role and is the communication bridge between the acquisition terminal and the smart meter.

[0003] However, with the large-scale popularization and use of carrier smart meters, problems such as unstable communication, communication frame loss, and difficult troubleshooting have emerged. Usually, when the smart meter fails to read the electricity consumption, the problem can only be troubleshot by temporarily inserting a communication line and connecting it to the computer monitoring software. On the one hand, this method is not stable enough, and on the other hand, it always occupies the computer and cannot monitor multiple meters simultaneously. Due to the very good fit of the pins between the carrier module and the meter, it is very difficult to connect a monitoring line between the two, and it is impossible to stably and conveniently monitor the communication messages between the two. Summary of the Invention

[0004] The utility model aims at the above problems and provides a smart meter with a carrier message monitoring module, which solves the defect that the communication messages between the existing carrier smart meters cannot be stably and conveniently monitored.

[0005] The technical solution adopted by the utility model is as follows:

[0006] The utility model discloses a smart meter with a carrier message monitoring module, including: a meter body, a three-phase message monitoring module, and a carrier module. A meter base is provided below the meter body, and a first pin serial port is provided on the meter base. Multiple groups of first pin serial ports adapted to the first jack serial port are provided on the back of the three-phase message monitoring module, and the three-phase message monitoring module is installed on the front of the meter base through the first pin serial port; multiple groups of second jack serial ports are provided on the back of the three-phase message monitoring module, and a second pin serial port adapted to the second jack serial port is provided on the front of the carrier module. The carrier module is installed on the front of the three-phase message monitoring module through the second pin serial port. In the current smart meter, the communication frequency between the carrier module and the meter is fast and the real-time performance is strong, but the problem occurs occasionally, which increases the difficulty of troubleshooting. If there is a problem with the communication between the carrier module and the meter, it is very difficult to capture comprehensive message information.

[0007] Optionally, multiple 485 pin terminals are provided at the bottom of the message monitoring module.

[0008] Optionally, multiple first installation grooves are provided on one side of the front of the meter body, and a rotating shaft is vertically installed in the first installation groove.

[0009] Optionally, a second mounting groove is provided on the other side of the front of the electricity meter body.

[0010] Optionally, an opening is provided on the side wall of the second mounting groove close to one side of the first mounting groove.

[0011] Optionally, a reinforcing groove is provided at the bottom of the electricity meter body. A plurality of first reinforcing ribs and second reinforcing ribs are provided in the reinforcing groove, and the width of the first reinforcing rib is smaller than the width of the second reinforcing rib.

[0012] Optionally, the 485 pin terminals are located between two adjacent groups of second reinforcing ribs.

[0013] Optionally, an outwardly protruding rib is further provided on the outer side wall of the reinforcing groove, and the cross section of the rib is semicircular.

[0014] Beneficial effects

[0015] 1. The intelligent electricity meter with a carrier message monitoring module of the present utility model adopts the method of attaching the message monitoring module between the electricity meter and the carrier module to realize the monitoring of the communication messages between the electricity meter and the carrier module. In this electricity meter, the back pins of the message monitoring module are inserted at the position of the carrier module of the electricity meter, and then the carrier module is inserted into the front jacks of the message monitoring module. When monitoring the message, the corresponding serial port on the serial port server can be opened by software to monitor the communication messages between the electricity meter and the carrier module in real time.

[0016] 2. Compared with ordinary electricity meters, the intelligent electricity meter of the present utility model has little increase in appearance volume and will not affect the meter installation position and space. This enables multiple electricity meters to be simultaneously connected to the serial port server to monitor the carrier communication messages of multiple electricity meters.

[0017] 3. The intelligent electricity meter with a carrier message monitoring module of the present utility model is very precise in dealing with the pin positions among the electricity meter base, the message monitoring module and the carrier communication module. In particular, the message monitoring module is mold-opened according to the actual situation, making the plugging and unplugging between the modules very simple and precise, truly achieving plug-and-play. In addition, in terms of message monitoring, the leads of the two-way 485 can be directly connected to the serial port server, which realizes that only one computer is needed to monitor the carrier communication messages of multiple electricity meters, making it more efficient and stable, and providing convenience for engineers to analyze communication problems.
