The invention belongs to the technical field of sensors, and particularly relates to a thermocouple or thermal resistor wireless transmission system, which comprises a front-end acquisition unit and a rear-end receiving unit, a plurality of gateway nodes and equipment end nodes are arranged between the front-end acquisition unit and the rear-end receiving unit, the communication transmission period of the gateway nodes is a fixed period, and the equipment end nodes are connected with the gateway nodes. The communication transmission period of the equipment end node adopts integral multiples of the fixed period, a communication protocol message between the gateway node and the equipment end node is divided into a synchronous frame and a data frame, and the load of the synchronous frame can be as low as 1 byte in a control command-free state; the equipment end node determines whether to receive the data sent by the gateway node by analyzing the synchronization frame, the equipment of the equipment end node is i
