[Chinese instrument network meter patent] creative limit, instrumentation invention. Today, we introduced a national invention-issued patentâ€”Internet of Things smart wireless remote water meter. The patent was applied for by Guangzhou Zhaoji Instrument Manufacturing Co., Ltd. and was authorized on May 24, 2017.
The utility model relates to the management of water meter's internet of things, especially the intelligent wireless remote water meter of the internet of things.
Background of the invention
The communication path between the Internet of Things smart water meter and its integrated management system is: data through the upper multi-level communication equipment, through the Internet network, to reach the Internet of things smart meter integrated management system. Because the long-distance communication technology and the Internet of things technology all have the problem of data transmission security, the information security management of the Internet of Things smart meter has great risks. With the use of remote communications equipment, data may be subject to errors and may be artificially modified, causing the Internet of Things smart meter to run out of control, which can result in the user being able to use the water from the water company's sales management system. Using the Internet, the Internet server is vulnerable to attacks. The information is read and tampered with without the knowledge of the users of the Internet of Things smart meter; illegal users forge the identity of replicating the Internet of Things smart meter device and enter the sales management system. Modifying the data and stealing water will cause the water company to suffer economic losses.
There are smart meters for the Internet of Things produced by different manufacturers on the market. Their safety management methods are different. If the water company uses different manufacturers' IOT smart meters, and they are managed in the same water distribution system, the Internet of Things smart meter can Without the management of the water sales management system, the water company will suffer economic losses as a result of arbitrary water use.
The water company's IoT sales management system is too large, involving multiple data transmission modules, multiple data management systems, and currently imperfect interconnection networks. The key links in these data transmissions are uncertain and easily generate data. Exchange errors are easily subject to human intrusion. As a result, the security of data exchange between the Internet of Things meter and the water sales management system cannot be guaranteed, causing economic losses to the water company.
It can be seen from the above situation that there are too many risk factors in the safety management of the Internet of Things smart water meter. These risk factors cause the economic losses of the water company. Therefore, it is necessary to make further improvements to the existing intelligent water meters for the Internet of Things.
Summary of the Invention
In order to overcome the above shortcomings of the prior art, the purpose of the utility model is to provide a smart wireless remote water meter for Internet of Things monitoring data transmission security and monitoring of the Internet of Things.
The technical solution adopted by the utility model to solve its technical problems is: the intelligent wireless remote water meter of the Internet of Things, including several remote water meter units, an internet of things system and a meter reading mobile terminal, wherein: the remote water meter unit includes an identifier A module and a storage security management module, wherein the meter reading mobile terminal includes a reading module and a transmission module, the meter reading mobile terminal is connected to the IOT system through a transmission module, and the reading module is connected to a remote water meter unit.
The figure shows the structure of the utility model
As a further improvement of the present invention, the marking module includes a unique two-dimensional code layer or bar code layer on the water meter cover. The reading module of the meter reading mobile terminal includes a scanning device, which scans the identification module to determine the address or other identification of the remote water meter unit, and also reads the unique decryption key generated on the module to connect the remote water meter unit. Access the user water usage through the data line access remote meter unit.
As a further improvement of the present invention, the reading module of the meter reading mobile terminal is connected with the storage security management module of the remote water meter unit. The storage security management module is provided with an encryption and comparison module, and the encryption and comparison module is configured with a unique key. The transmission module includes a wireless wifi transmission device or GPRS data
Transmission device. The connection between the meter reading mobile terminal and the remote water meter unit is completed, the water condition of the remote water meter unit is read at that time, and the connection to the Internet of Things system is performed through the transmission module.
Compared with the prior art, the utility model has the beneficial effects that: the utility model adopts the two-dimensional code as the identification of the remote water meter, further monitors the water meter management and information transmission of the water meter through the internet of things, and improves the internet of things of the smart water meter. The system ensures that the information data on the water meter is true, accurate and complete, and the management of meter reading is further improved.

The screw pump is a volumetric rotor pump, which is drawn and discharged by the volume change of the sealing chamber formed by the screw and bushing. The screw pump is divided into Single Screw Pump, double, three and five screw pump. The screw pump is characterized by stable flow, small pressure pulsation, self-absorption capacity, low noise, high efficiency, long life and reliable work. And its outstanding advantage is the transmission medium does not form the eddy, the viscosity of the medium is not sensitive, can deliver the high viscosity medium.
