The invention discloses a system for calibrating a distributed network camera by use of a travelling robot, and correlation methods. The system comprises the robot for establishing an environment map; and an artificial sign is arranged at the top of the robot. A server is in communicating connection with the robot and the network camera, for obtaining images of the network camera and rectifying the images by use of parameters in the network camera; coordinates of an artificial sign center in a network camera image coordinate system are also determined in the rectified images; and according to coordinates of a robot center in a robot map coordinate system and the coordinates of the artificial sign center in the image coordinate system, a conversion relation between the image coordinate system and the map coordinate system is resolved, and the distributed network camera is calibrated according to the conversion relation. The system and methods provided by the embodiments of the invention have the advantages of high system integration, high expansibility, fast calibration mode and the like, and can directly establish the conversion relation between the image coordinate system and the map coordinate system.

The invention provides method and equipment for automatically controlling rail-bound vehicles and tracks for rail-bound vehicles. The method comprising: monitoring and controlling speed of vehicles according to figures of each track such that vehicles move at any time at least with a lowest speed which permits vehicles to arrive in the next parking location (HP2) on the driving direction because of kinetic energy thereof when the driver is conking out. Vehicles travel according to a speed lower than the lowest speed calculated in order to arrive in the next parking location (HP2) on the driving direction when the driver is conking out within a predetermined ramp track interval according to the invention, characterized in that, measurement data aiming at vehicles are collected and analyzedat least in part of regions (TB1, TB2) calculated and determined based on track layout of related track interval. Herein, vehicles are ensured only by analyzing the measurement data aiming at vehicles in the part of regions (TB1, TB2) to implement the safe parking, and protection for vehicles are executed via vehicle braking.

The invention can greatly save the infrastructure cost for building the electricity supply system; moreover, the invention is safe and reliable in operation and is economical and energy-saving.

The invention discloses a butt-jointing method for a truss girder, which comprises the following steps of: a, guiding a to-be-erected girder to move along the direction of an erected girder till move to a preset position by a guiding girder; b, removing the guiding girder section by section and moving the to-be-erected girder along the direction of the erected girder; c, stopping moving when a distance between ports of the two girders reaches a preset distance, measuring a deviation between the position of the to-be-erected girder and a design position, roughly adjusting the position of the to-be-erected girder, and calculating and confirming the distance between the two girders; d, moving the to-be-erected girder according to the calculated and confirmed distance, and finely adjusting the positions of an upper chord pipe and a lower chord pipe of the to-be-erected girder, thereby aligning the two girders; and e, welding a plurality of fixing plates on a contact surface of the two girders, wherein the two ends of the fixing plates are respectively in fixed connection with the two girders. According to the butt-jointing method for the truss girder provided by the invention, the girders can be butt-jointed in air, the manufacturing of the girder and the butt-jointing operation application are more convenient and flexible, and the safety coefficient of the butt-jointing operation is also increased.

The invention discloses a gun-carriage-type removable gas energy soot blower comprising a soot blowing pipeline which is arranged in a fixed cover; and the fixed cover is provided with a support bracket. In the gun-carriage-type removable gas energy soot blower provided by the invention, the soot blowing pipeline of a gas energy pulse soot blower is fixed in the fixed cover which is convenient to move, so as to flexibly erect the soot blower according to the field use demand, thus greatly improving the convenience of operation, and being beneficial for improving the soot blowing effect of the heating surface corners.

The invention relates to the technical field of satellite positioning and navigation, and particularly relates to a networking method based on phase difference, device and a differential positioning system. The networking method based on phase difference provided in the invention comprises steps: based on differential correction data, the location information of a mobile base station in a stable state is obtained; according to the location information of the mobile base station, the distance between the mobile base station and the networking is calculated; and when the distance between the mobile base station and any networking does not exceed a preset distance, the mobile base station is added to the networking. The scheme provided in the invention can enable the networking to be elastically telescopic, a more flexible networking ability is further realized, and the networking cost is reduced.
