[China Instrument Network Instrument Industry] It is reported that Guangdong Mobile has recently developed a water meter intelligent meter reading application with local water companies. More than 600 households in Shenzhen Luohu, Nanshan and Pingshan New District have installed smart water meters to realize remote automatic copying. table. In each smart meter that is reloaded, Guangdong Mobile has a built-in SMD IoT card to transmit the residents' water meter data to the city water supply information service platform in real time, which is convenient and quick, and saves a lot of manpower and material resources. In addition, with the help of smart water meters, the water company can analyze the water data, find out abnormal conditions such as leaks, and arrange for maintenance personnel to follow up and dispose of it.
Xiao Bian also asked the mobile company's experts, the original and the smart meter with data transmission, the implementation of the data transfer of the "Patch-type Internet of Things card" is the mobile company's own Internet of things special network card, and experts said that the use of the Internet of Things card There is not much relationship with the type of water meter itself, and the Internet of Things cards are classified into patch-type and industrial-type SIM cards.
Water meter experts say Various existing remote water meters and meter reading systems in the industry have their own problems, and along with the continuous development of the Internet of Things technology, the Internet of Things water meter came into being. This kind of mobile phone communication module is embedded in each water meter and uses the GPRS method to send the data of each water meter directly to the main station (water supply company). The Internet of Things water meter technology, although it has just started to be used in water meters, is in accordance with the limited laboratories and From practical results, it is true that every aspect is better than the current remote water meter. Its characteristics are as follows:
• It does not need to collect equipment and directly form a communication network with the main station server, and the meter reading success rate and reliability greatly improve;
• There is no need for special construction work. Simply connect the water meter itself to the tap water pipe. There are no longer any problems encountered in the construction of the remote water meter and the additional project غير مجاز مي باشدts incurred.
Mobile experts say
GPRS networking mode This networking mode is provided by China Mobile. Through sensor network and network capture, a lot of things can be accomplished in the cloud of smart water. The platform for smart meter reading is very easy to implement. Through the management and control of each node, the data exchange between the terminal and the terminal, and the data exchange between the terminal and the person, the intelligent operation can be completed, and the entire pipe network can also be monitored.
The network used by the mobile Internet of Things meter Internet of Things meter is China Mobile's private network. The Internet of Things meter is divided into several parts, the base table part, the valve part, the reading table conversion unit, the control unit, and the communication module. According to the characteristics of the network, China Mobile has 2 modular components, 2G and 4G modules are complete, and the communication module M6310 is mainly used for communication because of the small flow required for water and gas meters. The module has several main features:
• Relatively low power consumption (Special considerations for power consumption under the same 2G platform);
• High reliability
• Because China Mobile is doing card data operations and traffic operations, it can issue SIM cards and has many different specifications.
Built-in SIM card China Mobile will build an industrial-grade SIM card into a chip built into the communication module, which solves the oxidation (product cycle 8-10 years) that the card is exposed to for a long time, and the oxidation will have some missing links. Therefore, the built-in SIM card to improve the reliability of the Internet of Things table is a relatively innovative work. At the same time, China Mobile is also planning that the module may directly integrate the device cloud protocol, which can give users one more choice. In this way, if the customer uses China Mobile's cloud platform, the development workload will be very small. At present, many companies in the industry have already cooperated with China Mobile.
Small make up
The modern IoT communication module will bring a revolutionary change to modern meter reading and data communications, and it will gradually enter our lives. For the water meter, some experts believe that it will work together with the ultrasonic water meter to completely change the current status and pattern of the water meter, which will make the water meter operation and copying more simple, reliable, stable and convenient!
