Description
Technical Field
The invention relates to the technical field of railway signal equipment maintenance, in particular to a railway signal mechanical room path query method.
Background
The railway signal machine room is a special house building for placing signal indoor equipment, and the running state of the stored railway signal equipment directly influences and controls the operation of a railway. When a signal device is in fault, indoor and outdoor equipment are often required to be overhauled simultaneously, but a signal mechanical room is often difficult to find, a path is more concealed, and the problem is more remarkable in a relay station or other unattended stations. When the signal equipment is in fault rush repair, the path searching is delayed for a large amount of time.
The positioning inquiry and searching path mode which is widely used at present is realized by using a satellite positioning and network dynamic map mode, namely: firstly, positioning the position to be reached, and searching the paths which can pass through the periphery by map and navigation software according to the position, so as to arrange the optimal paths. This is a "point-first-then-path" approach. The railway signal machine room is not a marked building, the building size is usually small, and the fixed point is difficult to realize in common software, so that the path is also difficult to obtain.
The Chinese patent CN 108303076A navigation method, device and electronic equipment provide a method for navigating by using two-dimension codes. The patent needs to set two-dimension codes in a reflecting destination and a current scene, and navigation is carried out in a mode of scanning the two-dimension codes of the current scene and selecting the reflecting destination, and path information reaching the geographic position of the target two-dimension code from the geographic position of the two-dimension code of the current scene is searched out and taken as a navigation path according to the geographic position of the two-dimension code of the current scene and the geographic position of the target two-dimension code. The realization mode is to create father and son nodes, identify and match, and offline operation can be performed to a certain extent. However, if the current scene or the target scene has no set two-dimensional code, the path cannot be searched. Although the off-line searching of the path can be realized by using the two-dimension code to store the position information, the method is still a mode of 'first-fixed-point and then-path', and cannot be applied to the conditions of fuzzy fixed-point, special road of the path and the like, namely cannot be applied to searching of the railway signal machinery room.
