Raising RMS-T automatic guiding system (hereinafter referred to as RMS-T) is specially researched and developed for double shield TBM hard rock tunneling machine during subway tunnel construction. After fully understanding double shield TBM subway construction technology, structure features of shield tunneling machine and on-site construction environment, Raising has solved many technical problems after three years, such as, âspherical flexible hingeâ, âstrong vibrationâ, âhigh dustâ, ânarrow measuring channelâ, meanwhile, this system is equipped with redundancy measurement to enhance reliability and stability of calculation results.
RMS-T can show attitude deviation, rolling angle, angle of pitch, azimuth angle, range, gross tunneling, horizontal tendency deviation, vertical tendency deviation and other attitude information for tunneling operators in graphics and digits. In addition, RMS-T also offers tube management, authority control, ground remote monitoring system, human attitude check software and other additional functions.
âEnvironmental adaptability: It can adapt to strong vibration and high dust.
âMeasuring channel: There is no laser ranging equipment in telescopic shield and it makes no demand on measuring channel.
âSystem constitution: The system has simple parts and is easy to maintain.
âSystem stability: The redundancy sensor installed on front shield can enhance measuring precision and serve as spare parts.
âShock absorption of total station: This system is equipped with shock-absorbing hanging basket to solve total station failure caused by its vibration.
âAttitude display: It can show the attitude deviation, attitude angle, range, gross tunneling, as well as horizontal and vertical tendency of planning line of front shield and supporting shield in graphics and figures in real time;
âLinetype calculation: This system can calculate wirecable linetype in element method and coordinate list method, check entry information intelligently and export linetype list, minimizing the occurrence probability of human error;
âTube management: This system can select the optimal splicing point location for universal and common tube, predicate the follow-up 1-20 loop tubes and type in the shield tail gap by hands and automatically;
âStatus monitoring:This system can monitor working conditions of all hardware and record hardware alarm information automatically;
âReference check: This system can check the measuring reference, its azimuth, horizontal distance and altitude difference automatically, moreover, which gives automatic alarm and stops the guiding in case of overrunning;
âData query: This system can inquire historical tunneling guiding data, system operating log and alarm information according to time and ring number, moreover, export the query results;
âMeasuring results: This system will show the detailed calculating results of guiding measurement to users through measuring information, in this way, users can check attitude by hands and report guiding data;
âUser management: Driver of shield tunneling machine, measurer and measurement supervisor are allowed to log in this system. Different limits of authority stand for different functions. It is good for reducing the misoperation risk.
