Advantages of GPRS Remote Power Meter Reading
The advantages of GPRS remote power meter reading:
At present, there are many technologies for meter reading in China. Such as manual meter reading, RS485, infrared and power line carrier, etc. Among them, the technologies of RS485 and infrared meter reading are relatively mature and widely used. Power line carrier meter reading can only be used in a small area.
RS485 meter reading requires wiring and can only be implemented in a small area (less than 1000 meters); infrared meter reading requires manual on-site meter reading; due to the influence of technology and the objective conditions of the domestic power grid, there are still many technical problems in power line carrier meter reading.
Now, the automatic meter reading system based on the GSM/GPRS/CDMA public network platform has become the mainstream of the meter reading industry. It not only completely solves the shortcomings of the above-mentioned meter reading methods, but also benefits users a lot from excellent network security and low operating costs. So that the establishment of meter reading system does not require expensive equipment and is not limited by space.
The timely and correct measurement of electric energy is directly related to the economic benefits of production and operation. The automatic meter reading system based on the GSM/GPRS/CDMA public network platform saves users the expensive network construction and maintenance costs. And there is no interval and regional restrictions, if there is a local system with a mobile phone signal, it can run stably. Among them, the GSM short message wireless meter reading system has ultra-low operating costs, which also enhances the applicability of the system. The meter terminal can actively report the meter data according to the set fixed-point timing, and the meter reading center can actively read the value of any meter at any time. And the data is automatically stored in the database, which is convenient for the operator to query later. The system can automatically generate daily reports, monthly reports, graph curves, etc., which are intuitive, correct, and efficient.
