Problems solved by technology

However, the addition of relay stations will increase the complexity of the system and increase the cost
[0006] For wireless mobile devices, data caching is adopted, and a lower reporting frequency is used in order to reduce power consumption, which is only suitable for occasions that do not require high real-time performance

Embodiment

[0042] Such as image 3 It is a refrigerated vehicle transportation monitoring system, which is used to monitor the refrigerated temperature and vehicle location information during the transportation of refrigerated vehicles.

[0043] The temperature and GPS / BeiDou sensors capture the temperature of the cooler and the location of the vehicle and send them to the microprocessor.

[0044] The monitoring server and the microprocessor jointly maintain the event library storage unit. The event library storage unit stores the events and response methods that the microprocessor needs to respond to. For example, the temperature value of the refrigerator cannot be higher than a certain value, otherwise an alarm will be issued; the GPS / Beidou signal cannot deviate too much from the predetermined route, otherwise the user will be reminded.

[0045]The microprocessor performs certain processing on the data, checks the storage unit of the event library, and judges whether an event is tri...

Abstract

The invention discloses a sensor network based on event bank triggering reporting. The sensor network comprises a network and a monitoring terminal. The monitoring terminal is provided with a sensor unit, a data processing unit, a communication unit and a power supply. The sensor unit is connected with the data processing unit and is used for sending data collected by the sensor unit to the data processing unit. The data processing unit achieves communication through the communication unit and the network. The power supply is used for power feeding. The data processing unit comprises an event bank which stores events which need real-time responding of a system and a response method corresponding to the events. When the events are not triggered, the sensor unit carries out high-density collecting on data, the data are stored in the data processing unit, timing uploading is carried out, or when network instruction checking is passed, the data are uploaded in a batch mode, and accordingly power loss of the sensor network is lowered. When the events are triggered, the sensor network processes the events preferentially, and accordingly real-time performance is guaranteed.

Description

technical field [0001] The invention relates to the field of information transmission, in particular to a sensor network that triggers reporting based on an event library. Background technique [0002] Data reporting is an essential part of sensor networks, especially for wireless sensor networks, the data reporting strategy has an important impact on the density and power consumption of data collection. In the existing sensor network, in order to realize the real-time reporting of a large amount of monitoring data, a wired data reporting method can be adopted. For wireless transmission systems, the method of relay amplification can be used. For wireless mobile devices, due to the strict limitation of power consumption, it is impossible to collect and report real-time data for a long time. A compromise method is to collect data in real time, cache the data, and wait for a long time interval or when the user queries , upload the cached data in batches. This method can redu...
