Embodiment Construction

[0028] The invention is mainly applied in the command system of emergency medical rescue, and improves the ability of emergency medical rescue by adding multiple communication channels to reduce the harm of disaster events to the life and health of the people. In addition to the three different channel modes provided by traditional operators such as China Mobile, China Unicom and China Telecom, it also provides channel modes based on satellite communications such as Maritime Satellite and Beidou Satellite, which expands the selection of optimal communication channels. It is conducive to the efficient work of the emergency rescue system in the event of a disaster.

[0029] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

Abstract

The invention discloses a method for automatically switching a communication channel, aiming at solving the problems that the transmission efficiency of the existing emergency rescue command system in the single communication channel is seriously limited by the working state of the communication channel, and a worker can not easily select the optimal communication channel mode from multiple communication channels. The method comprises the following steps of firstly evaluating the transmission quality of the plurality of available communication channels to generate an evaluation result; determining the optimal communication channel according to the evaluation result; if information data need to be received and transmitted, automatically switching the optimal communication channel by a working channel; and giving the network parameters of the working channel to computers of the receiving part and the transmitting part to establish the communication link between the information receiving part and the information transmitting part. A cache device is also added into the method, and is used for carrying out breakpoint recording on the information data when a network is temporarily disconnected and carrying out breakpoint resume on the information data when the network is connected again; and after the transceiving process is finished once, the information data of the this time in the cache device are deleted.
