Problems solved by technology
However, in practical applications, sometimes a host can communicate with up to 4 extensions, and the extensions do not communicate with each other. If a program-controlled switch is used, on the one hand, it will increase the cost of the equipment. In this case, the installation space is limited, and the number of modules will increase, and the number of connecting cables will increase accordingly, resulting in a decrease in system reliability.
figure 1 It is a connection diagram of a typical wired voice transmission local telephone in the prior art. If this solution is adopted in this communication equipment, it will inevitably lead to bloated equipment and complicated structure

The invention relates to the field of communication, and discloses a communication system. The communication system is characterized by comprising a power module, a wireless data transmission module, a display control audio module, a display and a keyboard, wherein the power module is respectively connected with the wireless data transmission module and the display control audio module; the wireless data transmission module is connected with the display control audio module; and the display and the keyboard are respectively connected with the display control audio module. The invention also discloses a communication method of the communication system and a control method of signals during wireless transmission. The communication system has the characteristics of simple circuit implementation structure, greatly reduced cost and safety and reliability for use; during wired data transmission, voice transmission and data transmission adopt different frequency channels so that voice-data compatible transmission function can be finished and remote transmission (more than 1 Km) of wired voice can be realized.
Description
technical field [0001] The invention relates to the communication field, in particular to a communication system, a communication method and a signal control method during wireless transmission. Background technique [0002] In general, the communication system needs two functions of wired digital / voice simultaneous interpretation and wireless digital / voice simultaneous interpretation. In the prior art, wired communication generally adopts program-controlled switching technology, which can realize voice and data communication between communication terminals. However, in practical applications, sometimes a host can communicate with up to 4 extensions, and the extensions do not communicate with each other. If a program-controlled switch is used, on the one hand, it will increase the cost of the equipment. In this case, the installation space is limited, and the number of modules will increase, and the number of connecting cables will increase accordingly, resulting in a decre...
