Description

An additional device for smart watt-hour meters that reminds payment by SMS

technical field

The utility model belongs to the technical field of an additional device for reminding payment of an intelligent electric meter, and in particular relates to an additional device for an intelligent electric meter for reminding payment by a short message.

Background technique

At present, among the electric meters produced in China, the smart electric meter has become a trend. This kind of electric electric meter has the characteristic that the power will be cut off immediately after the pre-purchased electric charge is completed. However, the user does not check the balance of the electric meter every day. When the balance of the meter is insufficient and the user fails to recharge the IC card in time, it will cause an automatic power outage, which brings a lot of inconvenience to the life and work of the user. Therefore, it is necessary to design an additional device for a smart watt-hour meter that reminds users to pay by text messages, so as to inform the user of the balance information of the watt-hour meter in time and remind the user to pay the fee in time.

Contents of the invention

The technical problem to be solved by the utility model is to provide an additional device for an intelligent watt-hour meter that reminds payment by a short message, which effectively solves the problem of power failure caused by the user forgetting to recharge the IC card.

The utility model adopts the following technical scheme to solve the above-mentioned technical problems, a smart meter additional device for reminding payment by short message, which is characterized in that it includes a meter data acquisition module, a GPRS module and a power supply module, wherein the meter data acquisition module passes through the data command bus Connected with the smart watt-hour meter, the meter data acquisition module is composed of the main processor AT89C51 single-chip microcomputer and the EEPROM data memory. Store the corresponding power consumption information data in the EEPROM data memory, connect the AT89C51 single-chip microcomputer and the GPRS module through a serial port communication circuit, and communicate wirelessly between the GPRS module and the user's mobile phone terminal through the GPRS wireless communication network, and the power supply module through the line respectively Provide power for the meter data acquisition module and GPRS module.

Further preferably, the data command bus is an RS485 bus or an M-BUS instrument bus.

The working principle of the utility model is: through the software design program, the purpose of controlling the GPRS module by the single-chip microcomputer is realized. When the data acquisition module of the electric meter monitors that the balance of the smart electric meter reaches the preset value, the AT89C51 single-chip microcomputer is used to control the GPRS module to send to the user's mobile phone terminal. SMS to inform the user of the meter balance information and remind the user to pay the bill in time.

The utility model has the advantages of simple structure, easy realization and low installation cost, and solves the problem of power outage caused by users forgetting to recharge the IC card, and the adopted GPRS mobile network is mature and reliable.

Detailed ways

The specific content of the utility model is described in detail in conjunction with the accompanying drawings. As shown in Figure 1, a kind of smart watt-hour meter additional device that reminds to pay by short message is characterized in that comprising ammeter data acquisition module, GPRS module and power supply module, wherein the ammeter data acquisition module is connected with smart watt-hour meter by data command bus, The data command bus is RS485 bus or M-BUS instrument bus. The meter data acquisition module is composed of the main processor AT89C51 single-chip microcomputer and EEPROM data memory. The meter data acquisition module is used to collect the electricity consumption information data of the user's smart meter. It is processed by the AT89C51 single-chip microcomputer, and the corresponding power consumption information data is stored in the EEPROM data memory. The AT89C51 single-chip microcomputer and the GPRS module are connected through a serial communication circuit, and the GPRS module and the user's mobile phone terminal communicate wirelessly through the GPRS wireless communication network. , the power supply module supplies power to the meter data acquisition module and the GPRS module respectively through the line.

The electric meter data collection module in the utility model is connected with the smart electric meter in the user's home through the data command bus, and the electric meter data collection module collects electric meter data every 10 minutes, and stores the data information in the EEPROM memory. When the balance of the smart watt-hour meter reaches the preset value, the AT89C51 microcontroller is used to control the GPRS module to send a short message to the user's mobile phone terminal to inform the user of the balance information of the watt-hour meter. This device has three preset values, which are 20 degrees, 10 degrees and 5 degrees respectively. When the meter data acquisition module detects that the balance of the smart meter is 20 degrees, the AT89C51 single-chip microcomputer is used to control the GPRS module to send a short message to the user's mobile terminal. Inform the user of the meter balance information. When the meter data acquisition module detects that the balance of the smart meter is 10 degrees, the AT89C51 microcontroller is used to control the GPRS module, and a text message is sent to the user's mobile terminal every three hours during 8:00-20:00 to remind the user to recharge. When the meter data acquisition module detects that the balance of the smart meter is 5 degrees, it will send a text message to the user's mobile terminal every hour during 8:00-20:00 to remind the user to recharge in time.

The basic principles, main features and advantages of the present utility model have been shown and described above. On the premise of not departing from the spirit and scope of the present utility model, the present utility model also has various changes and improvements, and these changes and improvements all fall into the scope of claims.
