Low-power consumption intelligent wireless sensor and control system thereof

Abstract

The invention provides a low-power consumption intelligent wireless sensor and a control system thereof. The control system is used for controlling multiple wireless sensing devices; the wireless sensing device comprises a SensorHub sensor interface module, a DataChannel data transmission module, a ModuleLogic logic control module, an HDFF data analysis module and a LoRa and NBIOT communication module; multiple interfaces of the wireless sensing device can be connected with multiple kinds of sensors simultaneously, uniformly preprocess and convert data of the sensors, include universal compatible interfaces of the sensors and are reused on a hardware circuit maximally; and data processing model logic is contained, the process that the original data of the sensors is calculated to obtain model results is processed on local equipment without uploading all the mass original data to a background to be processed, and therefore the bandwidth burden and the background complexity are avoided.

[0002] At present, the number of access devices of the Internet of Things is increasing widely and rapidly. The access of front-end devices with sensors is an important classification. Completing the value collection of a certain sensor and uploading it wirelessly is an important component of the Internet of Things, and it is also a trigger for the Internet of Things. The entrance to implement equipment linkage, but there are still limitations and deficiencies in front-end sensor access: single sensor layout, mostly only for the measurement of a certain indicator; a single sensor corresponds to a single wireless communication, forming an independent node, Limited functions; when multiple sensors correspond to a single wireless communication, there is no unified management, but time-division multiplexing; the uploaded data is often raw data, and the large data stream occupies wireless bandwidth and the workload of background recording and analysis is large; a single sensor device It is often impossible to restore the complete model locally, and it is difficult to form an effective trigger basis

However, the types of services and data rates provided by the 3G / GPRS public network are limited, and the cost of power grid monitoring and operation caused by communication fees is high

Since the above-mentioned technologies such as zigbee are only suitable for short-distance wireless transmission, but the power grid covers a wide area, the data of monitoring equipment has increased significantly, which in turn has greatly reduced the processing capacity of the entire network system, and the reliability of the monitoring system based on zigbee technology is difficult. Meet the requirements of the power system

[0004] At the same time, in the existing wireless communication mode, the design of the wireless communication module is too large, so it will cause problems such as bulky appearance, inconvenient portability, and huge cost.
