Method and device for interconnecting sensor network and mobile terminal and network connection equipment

Abstract

The invention discloses a method and a device for interconnecting a sensor network and a mobile terminal and network connection equipment. In the method, the sensor network gathers the acquired monitoring data of sensor network equipment to the network connection equipment through a field bus; the network connection equipment transmits the gathered monitoring data to a server via a carrier network; the server processes and analyzes the received monitoring data to obtain monitoring information of the sensor network equipment, which are corresponding to the monitoring data and stores the received monitoring data in a data base; the mobile terminal visits the server via the carrier network to obtain the monitoring information of the sensor network equipment and visits, controls or manages the sensor network equipment via the carrier network and the network connection equipment. The invention interconnects the sensor network and the mobile terminal by utilizing the network connection equipment, and thereby, the complexity of the sensor network equipment is reduced; a carrier network access device does not need to be configured for each equipment, thereby reducing the application cost.

Description

technical field [0001] The invention relates to a sensor network and a mobile terminal technology, in particular to a method and device for interconnecting a sensor network and a mobile terminal and network connection equipment. Background technique [0002] In the traditional monitoring system using sensor network technology, the RS-485 bus is generally used, but there are the following defects in practical applications: there can only be one master node on the RS-485 bus, and it is impossible to form a multi-master system. Once the master node If a fault occurs, the system cannot operate normally, resulting in poor reliability of the entire system. The anti-interference ability of the RS-485 bus is poor, it is not suitable for running in a high electromagnetic environment, and its error handling ability is also very poor. The data communication method is command-response, and the lower-end nodes can only respond after receiving the command from the master node, resulting ...
