Forwarding communication equipment and system and communication method

Abstract

The invention relates to forwarding communication equipment and a system and a communication method of parameters acquired by a sensor. The forwarding communication equipment comprises a first communication module for receiving parameter signals detected by sensor nodes, and a second wireless communication module used for coupling the parameter signals received by the first communication module to an electric conductor as a receiving end antenna, and the first communication module and the second communication module have different work frequencies. By employing the communication modules with two work frequencies, the widely applied sensor can be utilized, and the electric conductor can be used to transmit the parameter signals acquired by the sensor. Because the distribution scope of electric conductors is extremely wide, multiple base stations need arranging in the communication system, so that the cost is reduced and the communication system is simplified, and also the forwarding communication equipment and the communication system disclosed by the invention can be widely applied to various regions and occasions.

Description

technical field [0001] The invention relates to the field of signal monitoring, in particular to parameter measurement and communication of equipment. Background technique [0002] At present, sensors for detecting equipment performance parameters or working environment parameters have been widely used in industrial and medical fields. Often multiple sensors are located at different locations on the device. The wireless communication with a frequency of 2.4G Hz is mainly used to transmit information between the sensor and the control platform or between the sensors. For example, the widely used 2.4G Hz communication protocols include WIFI, Bluetooth and ZigBee. The communication distance of these communication methods is relatively short. For example, the communication distance of WIFI and Bluetooth is generally within 10 meters, and the communication distance of ZigBee is generally within 50 meters. For large equipment with many sensors (such as relatively long or high eq...

Problems solved by technology

Setting up multiple base stations results in increased communication costs and complicates the communication system

At the same time, the communication network of some sensors adopts the GSM communication network. Due to the limited coverage of the GSM network, it makes it impossible to communicate between the regional sensor and the control center in areas where GSM does not cover.
