Problems solved by technology
[0005] The technical problem to be solved by the present invention is that the existing automatic instruments can use remote data collection relatively easily, but it is difficult to extend this technology to daily life to realize the remote data collection and control of household gas meters. Generally, a meter with a WiFi module is used for data transmission, which is costly and complicated to operate. The purpose is to provide an intelligent valve-controlled gas meter based on the NB-IoT network, so as to solve the problem that existing automatic meters can use remote data easily. Acquisition, but it is difficult to extend this technology to daily life to realize remote data acquisition and control of household gas meters. Generally, instruments with WiFi modules are used for data transmission, which is costly and complicated to operate.

The invention discloses an intelligent valve controlled gas meter based on the NB-IoT network. The intelligent valve controlled gas meter comprises a client and a communication module, which establisha connection via the Internet, the communication module is connected to a field controller, and the field controller accesses a local area network formed by field devices; area division is performedon the user at first, a field controller is matched for each area, the field devices in the area form the local area network, the field controller is connected with at least one field device in the local area network to obtain the data of all field devices in the local area network, and then the data are sent to the Internet via the communication module, and the problem of the last one kilometer of data transmission is solved by the local area network effectively. The scheme has the advantages of effectively solving the cost control problem of the last one kilometer of automatic meters, and being convenient to popularize and high in reliability.
Description
technical field [0001] The invention relates to an automatic instrument, in particular to an intelligent valve-controlled gas meter based on an NB-IoT network. Background technique [0002] An automation instrument is an automation technology tool with relatively complete functions, which is composed of a number of automation components. It generally has several functions at the same time, such as measurement, display, recording or measurement, control, alarm, etc. The automation instrument itself is a system, but also a subsystem in the whole automation system. An automatic instrument is an "information machine", and its main function is the conversion of information forms, converting input signals into output signals. The signal can be expressed in the time domain or frequency domain, and the transmission of the signal can be modulated into a continuous analog or intermittent digital form. [0003] The cellular-based Narrow Band Internet of Things (NB-IoT) has become an...
