Description

Remote meter reading intelligent monitoring system based on NB-IoT wireless communication module
Technical Field
The utility model relates to a long-range intelligent monitoring system that checks meter based on NB-IoT wireless communication module.
Background
The smart city can not leave the internet, and the basis of the internet is interconnection and intercommunication of data. The multi-meter integrated information acquisition construction is adopted to construct a social utility terminal energy data acquisition and analysis platform, thereby being beneficial to reducing the comprehensive operation cost of the utility, realizing resource sharing and service intercommunication and effectively improving the overall service capability of the public field. The intensive national and local policies clearly indicate that the 'multi-form-one' information acquisition work needs to be vigorously promoted, and the information acquisition work is closely linked with the construction of smart cities.
The construction department standard JG/T162-2009 residential remote meter reading system is also called 2.0 edition standard, is the first international industry standard covering water, electricity, gas and heat meter centralized reading, and has higher theoretical level and certain foresight in the field of domestic public energy metering. The standard of version 2.0 puts forward the requirements for products such as water meters, gas meters, heat meters, electric meters and the like, and technical requirements for remote meter reading systems, is a reference standard for the research, production and detection of products of meter production and system integrators, provides a basis for the industry management and business guidance of departments such as tap water, gas (coal) combustion, heating power, power companies (bureaus) and the like, and promotes the development of the industry at that time. At present, the version is upgraded to 3.0, namely JG/T162-2016 civil building remote meter reading system.
In 7 months of 2015, the State department issued "guidance opinions on actively advancing the action of" Internet + ", in which" Internet + Intelligent energy "was specifically listed. The network infrastructure with the power grid and the communication network deeply integrated is deployed in a coordinated mode, shared is built together, and development of novel services such as family energy efficiency management and the like by means of the smart power grid is encouraged.
In 2016, the committee for improvement, the energy bureau and the ministry of industry and communications jointly issue ' guidance opinions about promoting ' internet + ' intelligent energy development ', ' the ability to improve the improvement ' (2016)392 number, and definitely proposes ' implementation functions of a rich intelligent terminal advanced measurement system, promotes the remote automatic collection and reading of water, gas, heat and electricity, and realizes the integration of multiple forms. "
In 2016, the State quality inspection administration issues a ' notice about implementation of 2016 action plans for measurement and development planning ', emphasizing that ' in the field of civil water, electricity, gas and heat energy measurement, the application of a powerful propulsion intelligent measuring instrument supports ' Internet + intelligent energy measurement and development '.
In the 4 th month in 2015, 30 th piece of Suzhou government has issued a measurement development planning (2014-2020) file for Jiangsu province, wherein the intensive key field measurement supervision informationized construction is particularly mentioned, a new civil three-meter supervision mode is explored, and a whole process supervision system for household electric energy meters, gas meters and water meters based on the technology of the internet of things is promoted.
The communication system is the key for ensuring the realization of the multi-table-in-one acquisition system, and the excellent communication system can realize good data information communication, thereby ensuring the smooth and high-quality completion of the data acquisition process. At present, the communication system construction technology applied in the 'multi-expression-in-one' project presents diversified characteristics, wherein the most widely applied technology mainly comprises the following technologies. (1) M-BUS communication. The system consists of a host, a slave and two communication cables, wherein the slave plays a role according to a control command of the host, and the system can ensure that a water meter, a heat meter, a natural gas meter and the like of a power consumer can obtain power supply of a power system, thereby realizing communication. However, in the application process, due to the influence of the structure composition, field wiring is needed, the engineering quantity is increased, and the difficulty of later maintenance is high. (2) And RS-485 communication. Although the technology is basically similar to the M-BUS communication system in the aspects of principle, composition and the like, the technology has obvious advantages and disadvantages in comparison. The advantages are mainly reflected in the aspects of high data transmission efficiency, long coverage distance and the like; the defects are mainly reflected in that: in the application process of the communication system, power sources cannot be provided for various measuring instruments, so that independent power line connection operation needs to be completed, and the engineering quantity is increased to a certain extent. (3) Micropower wireless communications. In the application process of the communication system, only wireless signals with power not more than 50mW and communication frequency band within 470-510 MHz need to be transmitted to the system, so that the system has very little engineering amount in the application process and the data transmission efficiency is ensured. However, since the communication signal is likely to be interfered during transmission, the specific application range is severely limited. (4) And (4) wireless public network communication. The system performs packet radio communication based on a public network, and is therefore ideal in coverage, applicability, transmission efficiency, and the like. However, considering that the coverage of the operators of the public network is not comprehensive and the operation cost of the equipment of the public network is relatively high, in practice, the utilization of the system may cause the loss of local information and the increase of investment cost. (5) The system is based on four-in-one communication realized by a power frequency power line. Because the popularization of the current power resources is basically realized, the system realizes the integration of four tables, can not only ensure the comprehensiveness and timeliness of data acquisition, but also effectively reduce the construction investment. However, in the communication process of the system, data transmission is subject to electromagnetic interference, and stability is impacted, so that the electromagnetic interference should be consciously optimized and processed in the application process. In the current 'multi-table-in-one' transformation project, a scheme commonly adopted is a scheme of power line carrier communication and micropower wireless communication.
The experience of the existing centralized acquisition and transformation engineering of 'multi-table-in-one' at home and abroad shows that a communication system is the bottleneck for realizing the 'multi-table-in-one' acquisition system and restricts the construction of a smart city. Narrow-band internet of Things (NB-IoT) based on cellular is an emerging technology in the field of internet of Things, and supports cellular data connection of low-power devices in a wide area network, which is also called low-power wide area network (LPWA). Although an emerging technology, the NB-IoT technology is rapidly developing and becomes an important branch of the internet of everything. The NB-IoT is constructed in a cellular network, only occupies a bandwidth of about 200KHz, and can be directly deployed in a GSM network, a UMTS network or an LTE network so as to reduce the deployment cost and realize smooth upgrading. NB-IoT supports efficient connectivity for devices with long standby time and high requirements for network connectivity. NB-IoT device battery life is said to be improved by at least 10 years while still providing very comprehensive indoor cellular data connection coverage.
The electric meter reading requirement is as follows:
the power meter reading scene comprises a user side communication system and a distribution network communication system. The frequency band of the power load monitoring system adopts a 230MHz +1.8GHz TD-LTE private network. The remote meter reading of the user electric meter adopts a plurality of technologies including GPRS, 3G, LTE, PLC, Zigbee, 433MHz and the like, the target of the meter reading frequency is acquisition and uploading once in 15 minutes and 96 points every day so as to realize the online monitoring control of a power grid.
The centralized meter reading is mainly adopted in places with centralized living such as China, the electric fiber centralized meter reading and the GPRS centralized meter reading (the percentage is more than 50 percent) are mainly adopted, and the independent meter reading is mainly adopted in places with scattered living such as Europe and America. Because the power meter reading and power supply are not problems and the data volume is relatively large, the urgent need of NB-IoT for power meter reading and utilization is not met at present.
Water meter reading requirement:
it is expected that the number of global intelligent water meters installed in 2016 will rise to 3250 thousands, accounting for over 30% of all water meters. At present, the installation proportion of the Chinese intelligent water meter is only 15%, and the annual composite growth rate is expected to exceed 30% from 2016. The incremental market for water meters has mostly adopted M-Bus communication. The inventory market for water meters is an opportunity for wireless water meters. The construction of the wireless water meter is simple, and due to the problems of power consumption, signal coverage and battery life, the NB-IoT technology is urgently needed to solve the practical problems.
The meter reading requirement of the gas meter is as follows:
the gas meter has high requirements on safety, and the testing time is 1-2 years. At present, the gas meter starts to use GPRS communication in large quantity, and the gas meter reads the data once a week, and the annual cost is about 6 RMB. At present, the cost of automatic meter reading is higher than the labor cost, but the gas faces the problem of step pricing. Due to issues of power consumption, signal coverage, and battery life, NB-IoT technology is urgently needed to solve the real problem, but the premise is to solve the security test problem.
