The remote real-time monitoring sub-system comprises a network cloud server and a plurality of network terminals, wherein real-time synchronization of the network cloud server and data of the on-site monitoring center are achieved through the Ethernet in the wired or wireless mode, and the multiple network terminals are respectively connected to the network cloud server. The mobile and emergency control sub-system comprises a handheld controller and / or an on-site emergency monitoring box, and the handheld controller and the on-site emergency monitoring box are respectively connected to the general monitoring station through the Ethernet in the wired or wireless mode.

Description

technical field [0001] The invention relates to the construction field, in particular to an intelligent informationized steel support remote real-time monitoring system based on Ethernet communication. Background technique [0002] In the foundation pit construction of underground construction projects, steel supports are required to avoid the collapse of the pit wall when excavating the foundation pit. The existing steel support end joints are generally in the form of movable joints and steel wedges, which are first lifted by a crane when used. The special jack preloads the axial force on the steel support, and then inserts the steel wedge to transmit the force. When it is necessary to dismantle the steel support, first use a crane to hang the special jack on the active head at the end of the steel support, and then pressurize the special jack through the hydraulic oil pump, so that the foundation pit enclosure structure will produce a certain amount of outward movement.

Problems solved by technology

However, in actual application, this kind of steel support also exposes its insurmountable shortcomings: during the installation process of the support, the prestressing process requires the cooperation of a crane and two loading jacks, and the pressure value depends on the experience and responsibility of the operator Center control, complex construction process and long time, no remote real-time monitoring data and control of support axial force and displacement during the use of steel supports; In addition, with the excavation and deformation of the foundation pit, the axial force of some supports will attenuate, and even the support will fail; There are many difficulties in the construction of adding axial force, which cannot solve the problem in essence; moreover, the installation and removal of the steel support requires the cooperation of the crane and the operator, and the process is complicated and unsafe, so it has the disadvantage of labor and time consuming
