The role of automatic meter reading and remote meter reading

In general, automatic meter reading and remote meter reading are together, and they are basically the communication scheme between smart meters and their meter reading systems, as well as collectors and concentrators.

Let's compare the advantages and disadvantages of several meter readings (screenshots).

Automatic meter reading and remote meter reading are the same thing.

Remote meter reading is to automatically collect the readings of various meters (water, electricity, gas, heating) under its jurisdiction to the management computer in real time or at regular intervals through the management platform software, communication network and collector, and automatically generate various reports to provide to the management unit, so as to realize metering and billing, self-service payment management, and replace the cumbersome, heavy workload and error-prone problems caused by manual meter reading.

Automatic meter reading, remote meter reading can avoid the total drawbacks of manual meter reading, not only to achieve remote meter reading, but also remote control, online payment, prepayment, ladder water price and other functions, convenient for the centralized and standardized management of the water supply department, effectively avoid arrears and other problems, users can check their own water situation and remote payment through the computer or mobile phone without leaving home, very convenient.

1. Remote meter reading. The remote automatic meter reading function is directly implemented in the central control room, and a regional meter reading network centered on the central control room can be formed.

2. Reliable communication. Due to the use of antenna fixed-point communication, after the installation height is completed according to the technical requirements, 24-hour communication can be carried out, and it is not affected by the fluctuation of the power grid.

3. Fast. Due to the high meter reading rate, about one meter per second, it is possible to read and bill for different periods.

4. Advanced technical means. Meter readings are identified through electronic eyes, and the electronic readings are strictly consistent with the meter head readings.

5. Periodic readings. According to different instructions, the central control room can read each meter in the network once a month, once a day or several times a day at a specified period.

6. It can be integrated with the charging system.

1. Four tables are copied.

The data is received by a remote server and processed and stored. 4.The remote server can provide data to the client for viewing and analysis through the API interface.

In general, the circuit book of the remote automatic meter reading system is a classic type of Internet of Things application. Through wireless communication technology, real-time collection and remote transmission of sensor data are realized, thereby improving the efficiency and accuracy of meter reading.

2. Remote meter reading is through such as RS485 interface line communication, the collected data is transmitted to the collector, the collector can save the hourly, daily and monthly data on the meter, and finally the management is carefully instructed to concentrate on processing, and the manager conducts remote meter reading on the smart meter through the computer.

3. First of all, the integrated nuclear chip of the smart meter collects the user's current and voltage in real time, and then calculates and analyzes the collected data through the microprocessor to obtain the amount of electricity (how many kilowatt-hours of electricity the user uses).

4. There are currently three ways to read the meter: a. Use the handheld computer (handheld) to copy directly from the main collector. If there is no main collector in the community, it can also be copied from the sub-collector respectively.

There are generally two kinds of handhelds: infrared and wired auspicious. The handheld is equipped with special software for meter reading.

5. Smart meters are different from traditional meters. The IC card meter is one that can be connected to the internet and can be read remotely. Remote meter reading is the most basic meaning of smart meters. There are many ways to achieve smart meter reading on how to achieve remote meter reading.

The tap water remote automatic meter reading system carries out unified management of the water consumption of large water users, installs flow meters on the water inlet pipelines of water users, and remote terminal equipment transmits flow data to the monitoring center. The tap water remote automatic meter reading system is compatible with a variety of wireless meter reading methods, monitors the user's water use process data, and discovers abnormal water use in time. The tap water remote automatic meter reading system can scientifically manage the meters, and find many problems such as meter distribution and leakage through data analysis.

The monitoring points of the tap water remote automatic meter reading system are mostly laid in the underground meter wells, usually there is no power supply, the environment is humid, and the meters are diverse, which brings great difficulties to the meter reading and measurement work. There are several main ways to read meters that can solve the above problems:

2. Save GPRS communication costs.

Generally, there are three main ones.

M bus, GPRS, micro-power wireless, i.e., this kind of automatic remote meter reading is based on its communication and transmission data interface and communication mode.

Wireless remote meter reading mainly includes three parts of smart meter + concentrator + set prepaid remote meter reading system, the communication between the three, that is, the transmission of data, instructions, information from the letter using wireless mode, then wireless communication generally has micro-power wireless, GPRS generally refers to satellite communication, 3G 4G 5G NB-IOL wireless communication, but also a PLC power carrier transmission number through wires, smart meters have this transmission of information module, The concentrator can receive dozens of such smart meters or RS485 meters that do not support wireless, and then transmit them to the server of the prepaid remote meter reading system through the network or wirelessly, which is OK, and the remote remote meter reading system is formed, which is also the working principle.

Wireless remote meter reading refers to the use of modern mobile communication technology and power system technology to combine technology, so that the traditional manual meter reading method is transformed into direct transmission of electricity consumption data through wireless network. It is also one of the typical applications of Internet of Things, wireless cities and smart cities. According to the mobile staff, the wireless meter reading service is actually through the wireless module mounted on the meter that records the water meter, electricity meter and other public utility data, and realizes the accurate and timely collection and processing of water, electricity, coal and other public utility data remotely.

These public sector devices then periodically send the collected data to the intelligent management platform via a wireless communication module, enabling remote meter reading.

As an important application of the combination of Internet of Things technology and urban public utilities, China Mobile Shanghai has carried out a city-wide wireless remote meter reading service upgrade, about one million household users have upgraded their meters, and the power company staff uses the ubiquitous mobile network to achieve remote automatic meter reading, which not only greatly saves the cost of manual meter reading for power enterprises, but also makes Shanghai citizens avoid the disturbance of door-to-door meter reading. Compared with the traditional manual meter reading service, remote wireless meter reading not only has the advantages of avoiding disturbing users and greatly saving the cost of manual meter reading, but also solves the constraints of wired line access restrictions in some places, reduces the dependence on lines, thereby reducing the cost of system construction, which is very in line with the goal of improving user experience and reducing costs with public institutions. After the full implementation of wireless meter reading, users can know their use of electricity meters more accurately, and the power department can also collect users' daily electricity consumption data.

In the future, users are expected to check how much electricity they use every day through the Internet or ** method, and enjoy open and transparent services. Moreover, the cost of upgrading is borne by the power company, and since the meter itself has to be replaced regularly, the investment in it does not increase much from the original, and there is no additional cost to residents.

Wireless remote meter reading is to use wireless networks such as China Mobile, China Unicom, China Telecom, and Electric Power 230 negative control private network to collect the meter-related data installed at the user's site to the master station for application analysis through the master station software built inside the power bureau. At present, the most common communication channels are GPRS and CDMA; The equipment that communicates with the master station is a network meter, a collection terminal, and a low-voltage meter reading concentrator. In terms of the functions of the main station, it includes file management, line loss analysis, electricity statistical analysis, power quality detection, load control, prepayment, meter reading and settlement, anti-theft detection, remote power consumption monitoring, etc.

There are many manufacturers who do remote meter reading, and the main station has Changsha Weisheng, Beida Jade Bird, Weitai, Hangzhou Huali, etc., and it is said that the market share of Changsha Weisheng's main station once reached 30%. Terminals and network meters are being done by almost all major meter manufacturers.

The M-Bus remote meter reading terminal realizes the function of reading the metering data of the heat meter in real time on site and uploading it to the management center through the GPRS wireless network. The M-Bus remote meter reading terminal supports heat meters produced by Kamstrup, Siemens, Landis+GYR, Enleman, Aetron, Fetra, Tiangang, Wei'an, Ruina, Etron, Zhenlan, Herdrumet, Danfoss and other companies. The metering data read includes:

Data such as heat meter ID, cumulative heat, current flow, current power, inlet temperature, return temperature, cumulative working time, actual current time, heat meter status, etc.

The meter is connected to the collector through wires, and the collector uploads the readings to the remote reading server through the network, and the remote meter reading can be realized.

The traditional smart meter user holds the IC card to the power supply department to pay for the purchase of electricity, and the power supply department uses the power sales management machine to write the purchased electricity into the IC card, and the user holds the IC card to swipe the non-contact IC card in the induction area (referred to as the card, the same below), and the power supply can be closed, and the card will be taken away after the power supply.

The current smart meter is different from the traditional mechanical meter, now mostly electronic and inductive, by the built-in integrated meter collector, collection board, collection module after the measurement data is collected, through such as RS485 interface line, power carrier, micro-power signal transmission to a concentrator (about 500 1000 units of centralized reception).

Then through the above three ways or GPRS, CDMA, network cable, etc., it is transmitted to the prepaid remote meter reading system of the collective society (generally the database server), so that the whole process of collecting readings from the smart meter to the concentrator, then to the remote meter reading system, and then to the user's prepayment inquiry (meter opening and closing management), and finally to the management end of the property power bureau.
