NB-IoT Non-magnetic Inductive Metering Module

Short Description:

HAC-NBA not-magnetic inductive metering module is a PCBA developed by our company based on the NB-IoT technology of the Internet of Things, which matches the structure design of the Ningshui dry three-inductance water meter. It combines NBh’s solution and non-magnetic inductance, it is an overall solution for meter reading applications. The solution consists of a meter reading management platform, a near-end maintenance handset RHU and a terminal communication module. The functions cover acquisition and measurement, two-way NB communication, alarm reporting and near-end maintenance etc, fully satisfying the needs of water companies, gas companies and power grid companies for wireless meter reading applications.

Functions

No	Function	Description
1	Touch button	It can be used for the near-end maintenance, and can also trigger the NB to report. It adopts the capacitive touch method, the touch sensitivity is high.
2	Near-end maintenance	it can be used for on-site maintenance of the module, including parameter setting, data reading, firmware upgrade etc. It uses the infrared communication method, which can be operated by a handheld computer or a PC host computer.
3	NB communication	The module interacts with the platform through the NB network.
4	Metering	Adopt non-magnetic inductance metering method, support forward and reverse metering
5	Disassembly alarm	The disassembly alarm function is disabled by default when the meter module is powered on. After installation and 10L metering, the disassembly alarm function will be available. When the module leaves the meter for about 2s, a disassembly alarm and a historical disassembly alarm will occur and trigger the NB to report. Reinstall the module and the meter normally to measure 10L, the disassembly alarm will be automatically cleared within 3s, and the disassembly will be restarted Alarm function. The historical disassembly alarm will be canceled only after successfully communicated with the communication module for 3 times.
6	Magnetic attack alarm	When the magnet is close to the Magnetoresistive element on the meter module, magnetic attack and historical magnetic attack will occur. After removing the magnet, the magnetic attack will be canceled. The historical magnetic attack will only be canceled after the data is successfully reported to the platform.
