Problems solved by technology

The power consumption in the transmitting state is large, the greater the transmission power, the greater the power consumption, and the lower the power consumption when receiving data, in this case, the more times the repeater transmits, the heavier the burden on the relay system will be. In systems powered by solar energy, wind energy or batteries, the traditional repeater relays all the data sent by the master station. The power supply system cannot support such a high frequency of transmission. It may even be charged during the day and the battery storage will be exhausted at night. can
It is even more difficult to maintain in a rainy climate

Embodiment 1

[0030] see figure 1 . The present invention provides a relay system for intelligent selective wireless data transmission. The master station communicates wirelessly with at least one slave station through the relay system. The relay system is provided with at least one repeater, and the repeater participates in wireless communication. Networking, at least one address segment is set in the repeater, and the address of at least one target slave station is stored in each address segment; the master station communicates with the corresponding target slave station in the address segment through the relay system .

[0031] In a preferred solution, the repeater is provided with two transceivers and an isolator, the two transceivers increase the degree of isolation through the isolator, and the two transceivers are connected by a data line, and the The repeater system is provided with a repeater, the transceiver of the master station is connected to one of the transceivers of the rep...

Embodiment 2

[0035] see figure 2 , the repeater includes two transceivers and an isolator, the two transceivers increase the degree of isolation through the isolator, the two transceivers are connected by a data line, the relay system is set A plurality of repeaters realize multi-level relay, and a plurality of repeaters transmit step by step through their transceivers, and the transceiver of the master station connects the transceiver of the first end of the first repeater through a wireless network, The target slave stations are all connected to the transceiver at the end of the final repeater through a wireless network.

[0036] When at least two repeaters need to be used in the communication link, multiple repeaters are set in turn between the master station and the target slave station, and the repeaters are bound in turn, and the first section of the first repeater The transceiver of the main station is connected to the transceiver of the master station, and the transceiver at the ...

Embodiment 3

[0040] When at least two repeaters need to be used in the communication link, multiple repeaters are arranged in a tree between the master station and the target slave station, and the repeaters are in a tree-like binding relationship. The transceiver at the first stage of the repeater is connected to the transceiver of the master station, and the transceiver at the end of the final repeater is bound to the corresponding target slave station, and the repeaters in the communication link are all bound with the target The slave station, the transceiver of the master station transmits data, and receives the data through the repeaters connected in sequence. After each repeater receives the data, it forwards the data to the target slave station bound to it and the next repeater. The transceiver at the end of the final repeater performs selective forwarding of the target slave station bound to it, avoiding unnecessary forwarding. The transceiver of the target slave station receives an...

Abstract

The invention discloses an intelligent selective wireless data transmission relay system. A master station wirelessly communicates with at least one slave station through a relay system, the relay system is provided with at least one repeater, the repeater participates in wireless networking, and at least one address field is arranged in the repeater, and the address of at least one target slave station is stored in each address field; the master station communicates with a corresponding target slave station in an address field through a relay system; selective forwarding of the master station or the target slave station is realized, unnecessary data transmission is reduced, and the burden of a relay system is reduced; through selective forwarding of the data, useless data transmission is avoided, the power consumption is reduced, and stable operation of the relay system is realized; by arranging the two transceivers, the bidirectional communication between the master station and the slave station is realized, the data delay is reduced, the uplink and downlink data interaction is rapid, and the market application value is good.

Description

technical field [0001] The invention relates to the technical field of relay systems, in particular to an intelligent selective wireless data transmission relay system and a relay method. Background technique [0002] In remote control, remote sensing, telemetry systems, and wireless data acquisition and control systems, star or tree topologies are mostly used, and data exchange is performed between the master station and the slave station. In the ultra-short wave frequency band, line-of-sight transmission is the main method. When the distance between the master station and the slave station is long or there are obstacles in the middle, the master station and the corresponding slave station will not be able to exchange data or the interaction will be unstable. , adding repeaters at appropriate locations can effectively solve the problem of distance extension. [0003] The relay system on the existing market does transparent transmission and does not identify the target slav...
