Multilateral master-slave switching communication method

Abstract

The invention discloses a multilateral master-slave switching communication method. The method comprises the following steps: 1, constructing a hardware system comprising a server and two intelligentterminals; 2, dividing the data into normal data and emergency data; 3, urgent events are divided into emergency events and very emergency events; 4, the intelligent terminal A transmits data to the server at regular time; 5, setting the intelligent terminal A as master equipment and the intelligent terminal B as slave equipment, reading normal data of the intelligent terminal B at regular time bythe intelligent terminal A, and then transmitting the data to the server; 6, when the intelligent terminal B detects an emergency event and a very emergency event, the intelligent terminal B requestsand switches to the main equipment; 7, after receiving the emergency data of the intelligent terminal B, the intelligent terminal A quickly transmits the emergency data to the server; and 8, after emergency data transmission is completed, the intelligent terminal B requests and switches to the slave device, and the intelligent terminal A recovers normal data transmission. According to the method,the delay rate of urgent communication of the system can be reduced when a single cable is used as a communication cable between intelligent terminals.

Description

technical field [0001] The invention relates to a control method for master-slave switching between intelligent terminal devices in an intelligent construction system of a dam hydropower station according to urgency requirements. Specifically, it is a communication method for multilateral master-slave switching. Background technique [0002] At present, domestic enterprises are conducting research in the field of intelligent construction of dam hydropower stations. The intelligent terminal equipment that has been developed is installed on the mechanical arm and cab of the mobile construction equipment of dam hydropower stations respectively. During the implementation of the project, it was found that the installation of the equipment has the following problems Difficulties: 1. The interior space of the cab of the construction equipment is relatively small, and basically there is no room for communication cables. 2. There is no communication cable channel reserved in the cab...

Problems solved by technology

[0002] At present, domestic enterprises are conducting research in the field of intelligent construction of dam hydropower stations. The intelligent terminal equipment that has been developed is installed on the mechanical arm and cab of the mobile construction equipment of dam hydropower stations respectively. During the implementation of the project, it was found that the installation of the equipment has the following problems Difficulties: 1. The interior space of the cab of the construction equipment is relatively narrow, and basically there is no extra space for arranging communication cables

2. There is no communication cable channel reserved in the cab, and the system bus wiring is very difficult

3. The mechanical arm of the construction equipment is covered with a large number of oil pipelines, and the oil pipelines need regular maintenance

5. Construction equipment is often hoisted from the parking place to the construction site by the cable crane. During the hoisting process, obstacles will be encountered from time to time, causing the communication cable to hang up

This method cannot solve the problem that the two smart terminals are required to perform master-slave switching according to the urgency and quickly transmit the urgent data.
