Embodiment 1
[0104] In this embodiment, a Hall sampling passive water meter is used, which uses a circular permanent magnet between N and S poles as a position recognition device; uses 5 Hall sensor chips to obtain the position of the character wheel of the water meter; uses Ultra-low power consumption chip sampling, reducing sampling power consumption and failure rate; adopting overall low power consumption design, suitable for various communication methods;
[0105] After the data is collected and processed by the multi-source data acquisition module and the data processing module, the data set A is obtained, and the communication time of the water meter in the running state is included in the data set A, which is denoted as A(x)={a 1 、a 2 ,...,a x}; where a 1 、a 2 ,...,a x Respectively, the communication time of the 1st, 2nd, ..., x times;
[0106] Establish a Kalman filter prediction model, and take the set A(x) as input data, then:
[0107] Establish a linear prediction model: a...

Description
technical field [0001] The invention relates to the technical field of water meter performance testing, in particular to a wireless network-based water meter comprehensive performance testing system. Background technique [0002] In recent years, the Internet of Things has become popular in China, and a large number of smart Internet of Things water meters have been installed. This is just a change in the communication method of the smart water meter, and it is also actively exploring the collection of water meter flow. [0003] There are various sampling principles for water meters. At present, photoelectric pulse counting, photoelectric direct reading, non-magnetic sampling counting, ultrasonic measurement, etc. are commonly used. In addition to the photoelectric direct reading meter, other sampling methods require the water meter to be powered on all the time, and the sampling pulse counting, non-magnetic sampling and other principles, all due to voltage fluctuations, in...
