The invention discloses an in-hole real-time positioning system and method for a shield construction method horizontal transport locomotive, and the system comprises a plurality of key point induction modules, a central control room UWB server, a plurality of microwave base stations, a locomotive UWB tag, a tailstock UWB tag, a vehicle-mounted industrial control computer, a vehicle-mounted microwave communication device, and an encoder. The invention relates to the technical field of subway or high-speed rail shield construction method tunnel construction. Compared with an existing manual position reporting and RFID mode, the in-hole real-time positioning system and method for the horizontal transport locomotive in the shield construction method can obtain more accurate position information, initial position calibration is conducted through high-precision positioning of key points, decimeter-level accurate positioning in a running interval can be achieved, the position information is transmitted back to a central control room in real time, and the real-time positioning effect is achieved. Compared with an existing manual reporting mode, the method is not limited by the communication distance, compared with an existing RFID mode, the construction cost and the maintenance difficulty are greatly reduced, and the maintenance cost caused by frequent damage of RFID tags can be reduced.
Description
Technical field [0001] The invention relates to the technical field of subway or high-speed railway shield tunnel construction, in particular to a tunnel real-time positioning system and method for a horizontal transport locomotive with shield method. technical background [0002] Tunnel engineering is a series of construction work in building underground, underwater and mountain buildings (laying railways and roads), which is mainly divided into tunnel planning, survey, design, through control survey and construction work. According to their location, tunnels can be divided into three categories: mountain tunnels, underwater tunnels and urban tunnels, among which mountain tunnels are built the most. The construction process of road tunnels mainly includes tunnel planning, survey, design, through control survey and construction, etc. To shorten the distance and avoid big ramps, those that pass under mountains or hills are called mountain tunnels, while those that pass under river...
