There are several main problems to be considered in the intelligent meter reading system of 4G industrial modem:
With the application of electronic technology and SCM technology in the electric meter, the emergence of smart meters can be generally divided into electromechanical and all-electronic with microprocessor. The machine core of the original induction watt-hour meter is used to measure the power consumption of the user by reading the revolution of the turntable through the photoelectric sensor, such as magnetic card meter, electric card meter, IC card meter, etc. The all-electronic watt-hour meter converts the A/D through voltage and current isolation, multiplies the sampling value, and calculates the user's power consumption cumulatively.The electromechanical smart meter has low cost, is mainly used for single-phase watt-hour meters, and is suitable for residents to use. The all-electronic ammeter is mainly used for charging three-phase electricity in enterprises. In order to realize remote automatic wireless meter reading, smart meters equipped with communication interfaces should be selected, which usually include RS-485, RS-232.CAN bus transceivers or infrared.
The core of the LTE 4G Cellular modem remote wireless meter reading terminal is to use computer network and communication technology to automatically count the power consumption of each user through the 4G wireless network and send it to the remote monitoring center to realize the automation of meter reading. Here we focus on the meter reading mode of 4G wireless network transmission.
4G wireless communication is not limited by time and region. Sixin LTE 4G Cellular Modem Wireless Meter Reading Module The Sixin LTE 4G Cellular Modem Wireless Meter Reading Module can be online for a long time as long as it takes time for wireless meter reading. The management center can obtain the accurate data of the electric meter at any time through the computer.
In the 4G industrial modem wireless transmission module meter reading system, the wireless transmission module is equivalent to an intelligent management machine.
Its main functions are as follows:
First, it collects and processes the data of each watt-hour meter (such as the number of watt-hour meters and the status of watt- hour meters), and then transmits the data adapter to the central platform through the communication medium according to the requirements of the central platform.
The second is to store the address of the ammeter according to the command of the central station and set the important parameters of the ammeter (such as ammeter constant and ammeter base); Thirdly, it has the function of networking, which can communicate with multiple meters or point-to-point signals and transmit data.
