Wireless Sensor Monitoring System: Timed Upload Function Analysis

By sdga:NiceRF Wireless Technology Co., Ltd

NiceRF Wireless Technology Co., Ltd. independently developed a wireless network multi-point sensor monitoring system. The system adopts wireless networking mode for temperature, voltage acquisition and real-time monitoring.


Wireless Sensor Monitoring System composition

The wireless network multipoint sensor monitoring system is divided into acquisition terminal and centralized terminal. The modules used in the two parts are the si4463 wireless modules independently developed by NiceRF. Each network consists of a centralized terminal and 64 measurement terminals (expandable to 3000 measurement terminals). The same environment can allow 40 networks to exist simultaneously.

Wireless Sensor Monitoring System composition

The measuring end consists of multiple function blocks such as temperature acquisition, battery voltage measurement, timing upload, automatic time synchronization, wireless configuration parameters, and low power consumption.

The centralized end consists of wirelessly collecting data from each measurement end, LCD screen display, wireless configuration parameters, RS485 output and other functional blocks. The centralized terminal can also be connected to the computer for parameter modification, and the parameters of each collection terminal can be modified wirelessly.

Wireless Sensor Monitoring System: Introduction to timing upload function

The timing upload function of the temperature measurement end is compatible with the requirements of low power consumption and real-time performance. Compared with the polling mechanism, the flexibility and real-time advantages, battery life can be better controlled. Software development is relatively complicated.

The temperature measurement end collects the temperature according to a time interval we set and uploads it to the centralized end, and then uploads it to the server from the centralized end. For example, if we set the time interval to 64S, the temperature measurement end will upload the collected temperature to the centralized end every 64 seconds.


Wireless Sensor Monitoring System: Advantages of timed upload function

It allows customers to weigh the choices in terms of data real-time and usage time.

The sensor monitoring system's acquisition interval can be wirelessly airborne (without disassembly and other ancillary tools to save costs).


Wireless Sensor Monitoring System: How to realize the timing upload function

After the Wireless Sensor Monitoring System collects the temperature, the upload time interval can be arbitrarily set according to customer needs. The larger the acquisition interval, the smaller the average current of the temperature measurement terminal and the longer the battery life, but the real-time data is poor. The opposite is true.
