The invention provides an expressway traffic flow early warning control device and an early warning control system, and relates to the technical field of traffic flow control boxes, the expressway traffic flow early warning control device comprises a control box, the surface of the control box is electrically provided with a display screen, the side wall of the control box is provided with three wiring ports, and the side wall of the control box is electrically provided with a wire. A heat dissipation plate is fixedly mounted on the side wall of the control box, a replacement structure is arranged on the surface of the control box, and the replacement structure comprises a limiting mechanism for limiting a filter cloth roll, a sealing mechanism for conveniently and tightly sealing a filter cloth strip and a temporary fixing structure for tensioning and fixing filter cloth. The limiting mechanism comprises a fixing plate, and the fixing plate is fixedly connected with the side wall of the control box. According to the control box, by arranging the replacement structure, regular replacement work of gauze at the heat dissipation plate is facilitated, and the situation that dust is accumulated on the inner walls of heat dissipation holes at the heat dissipation plate is reduced, so that normal heat dissipation of the control box is guaranteed, and normal operation work of the control box is guaranteed.
