Abstract

This invention provides one kind of long-distance supervisory and control and maintenance system of pneumatic caisson nobody construction equipment. Transducer signal is collected by transducer signal collecting and processing module for optoelectronic switching and analog-to-digital conversion, the signal after conversion is used as watch dog intelligence body to pre-diagnosis information entry of signal processing module, the result of prediction and evaluation is transferred to display module one way, the other way is transferred to network information processing module, capability state information of equipment is read by display module to real time display state information of all equipments. Network information module read equipment capability state information from watch dog module according to specific information, and the state information is sent to server through network. The information is saved by server for user long-distance supervisory and control and maintains the equipment through network. Equipment capability is evaluated and predicted to prevent the loss to caisson from fault, and long-distance supervisory and control and intellectual maintenance is realized through network.

Description

technical field [0001] The invention relates to a monitoring and maintenance system used in the technical field of detection, in particular to a remote monitoring and maintenance system for unmanned construction equipment of a pneumatic caisson. Background technique [0002] The basic principle of the unmanned air pressure caisson construction method is to send compressed air equivalent to the pressure of groundwater to the working room at the lower part of the caisson to prevent groundwater from seeping into the working room, that is, to use compressed air to suppress groundwater. No one enters the box during the operation, and all operations are completed by remote control machinery. The operation time is not limited, the excavation efficiency is high, and the construction is safe and reliable. This construction method also has the advantages of small construction space, high structural strength, and small impact on the surrounding environment. , so this kind of constructi...
