The invention relates to an outdoor construction equipment wireless network control system on basis of private protocol. The invention creates: 1, a novel real-time control WLAN (Wireless Local Area Network) structure, wherein the signal propagation of the system is not limited by the sighting distance, a signal can be diffracted and the communication barrier cannot be caused due to blocking, and thus, the communication propagation characteristic of the wireless network structure is very suitable for large-scale mobile construction equipment and is particularly suitable for joint control between equipment groups and the characteristic has very high using value; and a private protocol stack for controlling a wireless network in real time on the basis of a carrying and erecting device controller structure, wherein due to the adoption of the private protocol, the efficiency of a monitoring system can be improved and the data processing capacity is improved, the sealing performance of the private protocol is very beneficial to the safety of the system, an invasion approach is limited in a very small range, a designer can unhurriedly adopt corresponding countermeasures and an unsymmetrical bus structure is adopted on a real-time WLAN data link layer.
