Redundant communication system of valve cold voting system, control method and device of redundant communication system and medium

The invention discloses a redundant communication system of a valve cooling voting system, a control method and device of the redundant communication system and a medium. The system comprises at least two valve cooling decision modules, at least two switches and a plurality of valve cooling voting modules. The number of the valve cold voting modules is an odd number greater than or equal to three; each valve cooling decision-making module is connected with each switch; each switch is connected with each valve cooling voting module; the valve cooling decision-making modules are connected with one another; the valve cold voting module is used for voting to obtain a voting result, and transmitting the voting result and the operation state signal to the switch; the switch is used for transmitting the voting result or the operation state signal to the valve cooling decision module; and the valve cooling decision module is used for determining a control method for the valve cooling system according to the voting re
