Abstract

The invention provides a NB-IoT valve controlled dry reed tube Internet of Things water meter. The NB-IoT valve controlled dry reed tube Internet of Things water meter comprises a NB-IoT module and aWIFI unit; through a general asynchronous serial communication bus, the NB-IoT module and the WIFI unit are respectively connected with a central processing unit in a communication mode, a communication control unit first selects the NB-IoT module for communication, in the absence of the NB-IoT coverage, the NB-IoT module is automatically transfered to the WIFI for communication; a dry reed tube core unit is added, and connected with the central processing unit, measured pulse value can be received in real time; through a display unit, the working state information of the water meter is displayed dynamically; through a wake-up switch unit, water meter state can be awakened manually or regularly awaken. According to the NB-IoT valve controlled dry reed tube Internet of Things water meter, the water consumption situation can be controlled through the user's water meter, manpower, material and financial resources are saved, and the efficiency of production is improved. The adopted operator led wide-area low-power NB-IoT technology has the advantages of wide coverage, large capacity and high reliability, is especially suitable for water terminal connections in urban areas. Intelligentmeter reading management is truly realized, and substantial industry promotion is brought to the smart meter industry.

Description

technical field [0001] The invention relates to the field of Internet of Things water meters, in particular to a reed switch type Internet of Things water meter based on NB-IoT valve control. Background technique [0002] The Internet of Things is a comprehensive technology and application based on computer science, including network, electronics, radio frequency, induction, wireless, artificial intelligence, barcode, cloud computing, automation, embedded and other technologies, which can make isolated items (refrigerators) , cars, equipment, furniture, goods, etc.) are connected to the network world, so that they can communicate with each other and come alive. [0003] NB-IoT (Narrow Band Internet of Things, narrowband Internet of Things based on cellular network) technology adopts designs such as ultra-narrowband, repeated transmission, and simplified network protocols to obtain LPWA (Low Power Wide Area, low-power wide-area technology) the carrying capacity of the Intern...
