Application of GPRS Remote Meter Reading System in anti stealing electricity

　　The remote meter reading system is designed to realize real-time and reliable remote data reading of three meters (electricity meter, water meter and gas meter). The device realizes the remote meter reading task () with the triple network structure of star / vertical line / radio communication. N meters are connected with a data collector (such as jy-rtu4100 or jy-rtu-6120) through the star network. The data collector is connected with the radio station through the vertical line network. A vertical line network can connect m collectors (e.g. M = 128). Therefore, a subnet can connect nm = 32 × 128 meters share a radio station. This is a triple network structure composed of star type, vertical line type and wireless type. The constituent elements of this network structure are electricity meter, water meter or gas meter (hereinafter referred to as three meters), data collector and radio transceiver.

　　GPRS wireless Internet remote meter reading system realizes highly automatic management and automatically reads the current of user's instrument Voltage, record the user's voltage loss Loss of current time, as well as the mismatch between power and electricity meter, so as to realize the monitoring of each node of the line and provide real-time basis for anti power theft.

　　Application of GPRS Remote Meter Reading System in anti stealing electricity

　　1、 Introduction to GPRS

　　GPRS is the English abbreviation of gerneral packer radio ser vice, which is translated into general wireless packet service in Chinese. Specifically, GPRS is a high-speed data processing technology, that is, it transmits data to users in the form of packet. Therefore, GPRS technology can save time, labor and cost. For example, GPRS is like ADSL of mobile communication equipment, and GSM is an ordinary fixed telephone line.

　　The three outstanding advantages of general wireless packet service are:

　　(1) The high-speed data transmission speed is l0 times higher than that of GSM, which can meet your ideal needs. It can also stably transmit large capacity and high-quality audio and video files, which can be described as an extraordinary great progress.

　　(2) Always online: since it takes almost no time to establish a new connection (i.e. there is no need to establish a call connection for each data access), you can keep in touch with the network at any time. For example, without GPRS support, when you are roaming the Internet and there is telephone access, in most cases you have to disconnect and connect the call, Dial up again after the call. This is really a very annoying thing for most people. With GPRS, you can easily solve this conflict.

　　(3) Charging only by data flow: that is, charging is based on the amount of data you transmit (e.g. when downloading information online), rather than charging by the time you surf the Internet, that is, as long as you do not transmit data, even if you are "online" all the time, you do not need to pay. For example, when using GSM + WAP mobile phone to access the Internet, it is like charging when the phone is connected; Using gpre + WAP to surf the Internet is much more reasonable, just like there is no charge for telephone connection, and the charge is calculated only during conversation. In short, it truly embodies the principle of less use and less payment.

　　2、 Brief introduction of GPRS Remote Meter Reading System

　　GPRS wireless Internet remote meter reading system is a management system integrating computer technology, network technology, communication technology and automatic measurement technology. It realizes the remote measurement, monitoring, control, communication and data acquisition of various electric parameters, so as to realize highly automatic management. As long as the management personnel are in the central management room and use the network browsing function, they can see the whole system at a glance and monitor the power grid operation all day. All physical quantity data in the system are displayed on the screen, report the parameters of various electric quantities and power grid operation parameters at any time, and give an alarm in time in case of failure, Take it leisurely and unoppressively, we can grasp the problems of production and solve the problems that are encountered in the production. We should take effective centralized scheduling management and change the passive management mode into active management mode instead of new computer information management. Let new, fast and simple working methods be included, and truly realize the automation of production management.

　　GPRS Remote meter reading system, the user terminal is always online, automatically sends real-time data of on-site working conditions, and can respond to the query and control instructions of the central computer in time. The central computer is equipped with network database and powerful data processing software to realize wide area network data sharing and mobile office of main leaders. It overcomes the shortcomings of telephone remote meter reading and GSM short message remote meter reading, and integrates all the advantages.

　　4、 Application of GPRS Remote Meter Reading System in power theft prevention

　　With the rapid development of economy and the continuous increase of power consumption, the problem of power theft has become more and more prominent. Reverse connection, cross connection, forged lead seal and the use of inverted meter, the technology of power theft has become increasingly intelligent and the behavior of power theft has become more hidden, resulting in serious power loss of power supply enterprises and huge economic losses to the company. The problem of stealing electricity has affected the normal power supply and consumption order of power enterprises. Therefore, only by better improving the technical level of anti electricity theft, completely blocking the loopholes of electricity theft and creating a good order of power supply and consumption, can we better serve the economic development of our county. GPRS Remote meter reading system can realize the effect of anti electricity theft by recording the abnormal conditions of metering devices in real time.

　　Automatically record the current and voltage of the user's instrument, record the user's voltage loss, current loss time, and the mismatch between the power and the electric quantity of the meter, so as to realize the monitoring of each node of the line and provide real-time basis for anti-theft.

　　(1) GPRS Remote meter reading system can provide more accurate theoretical line loss calculation basis. According to the actual parameters of the line and combined with the current, voltage, power factor and other parameters copied by GPRS Remote meter reading system, the accurate monthly, daily and even hourly theoretical line loss can be calculated, which can be compared with the actual line loss copied in real time as a guide for checking power theft.

　　(2) Application of GPRS Remote Meter Reading System in the prevention of power theft of key users: use the computer to process the data remotely copied by GPRS of key users in real time, and analyze the power parameters of users. If there are abnormalities (loss of voltage, loss of current, current multiplied by voltage, power multiplied by time, power factor, etc.), the possibility of power theft or meter failure of the user will not be ruled out.

　　(3) Application of GPRS Remote Meter Reading System in key line anti stealing. Install high-precision high-voltage metering devices on key lines and branches, and determine the branches with large line loss through the analysis of GPRS Remote Real-time meter reading system, so as to narrow the inspection scope and facilitate the centralized inspection of key suspected power theft households.

　　(4) GPRS Remote meter reading system can monitor the switch status and opening times of meter box of metering device in real time, and give real-time alarm and record the behavior of opening meter box without authorization.

　　(5) GPRS Remote meter reading system can analyze the daily (monthly) curve of line loss according to the real-time data, and determine the abnormal line or branch through the comparison with the theoretical line loss, so as to find the behavior of unauthorized wiring and power consumption on the power supply facilities of power supply enterprises and bypassing the power consumption metering device.
