Abstract

The invention discloses an environmental temperature and humidity collecting system based on PLC power line carriers. The environmental temperature and humidity collecting system comprises a slave station collection module, a master station communication module and a cloud service platform. The slave station collection module and the master station communication module are in PLC communication, and communication is carried out through a circuit formed by a live wire and a null wire. A wireless communication module is arranged in the master station communication module, and the master station communication module is in communication with the cloud service platform through the wireless communication module. The advantage of collecting household temperature within a large range by a heat supply company is achieved.

Description

technical field [0001] The invention relates to an environment temperature and humidity acquisition system based on PLC power line carrier. Background technique [0002] At present, power carrier communication is PLC, which is the abbreviation of English Power line Communication. Power carrier is a unique communication method of power system. Power carrier communication refers to the technology of high-speed transmission of analog or digital signals through the carrier mode by using the existing power line. The biggest feature is that there is no need to re-establish the network, as long as there are wires, data transmission can be carried out. [0003] In the existing temperature and humidity environment collection systems, wired transmission technologies such as 485, Ethernet, etc. are generally used, which are not suitable for placement in residents' homes. The use of wireless solutions such as zigbee is also affected by the transmission distance; the use of GPRS can al...
