It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments described herein can be implemented in an order other than that illustrated or described herein.

[0051] For ease of understanding, the specific process of the embodiment of the present invention is described below. Figure 1 , an embodiment of a three-dimensional visual operation and maintenance management method applied to rail transit in an embodiment of the present invention includes:

[0052] 101. Obtain location data of N vehicles to obtain a location data set, where N is greater than

[0053] A positive integer greater than 2;

[0054] In this embodiment, N vehicles are distributed at various locations in the entire rail transit transportation network, and the location data of the N vehicles are directly acquired, wherein each location data carries a timestamp of sending and receiving.

[0055] 102. Analyze the timestamps corresponding to all the location data in the location data set, and extract the maximum timestamp and the minimum timestamp;

[0056] In this embodiment, what is compared are the receiving timestamps of the location data sent by N vehicles. The receiving timestamps are taken as the objects of comparison, the timestamps are sorted, the difference between the first receiving time and the last receiving time in the timestamps is captured, the first receiving timestamp is determined as the minimum timestamp, and the last receiving timestamp is determined as the maximum timestamp.

[0057] 103. Determine whether the difference between the maximum timestamp and the minimum timestamp is greater than a preset time threshold;

[0058] In this embodiment, the maximum timestamp and the minimum timestamp are first converted into binary data and then subtracted to obtain a numerical value, which is then converted into a time format to determine whether the difference in duration is greater than 80 ms.

[0059] 104. If the time is greater than the time threshold, modify the communication transmission path of the location data in the location data set and reacquire the location data of the vehicle;

[0060] In this embodiment, if it is greater than 80ms, it means that there are vehicles with abnormal communication in the rail transit network, then the communication transmission path of the vehicle with abnormal communication is changed, and after the change is completed, the position data of N vehicles are read again to determine whether there are any vehicles with abnormal transmission.

[0061] 105. If it is less than the time threshold, the punctuation data of all preset sensors are obtained, and based on the Unity platform system, all the punctuation data are three-dimensionally visualized to obtain a three-dimensional visual operation and maintenance graph of rail transit.

[0062] In this embodiment, if there is no abnormality, the punctuation data of the sensors installed under N vehicles are read. The sensors are installed and distributed throughout the vehicle according to the outline of the vehicle. The punctuation data is filled in a matrix in a fixed format, and the written matrix is ​​sent to the Unity platform system to construct a three-dimensional image. The three-dimensional image fed back by the Unity platform system is received to obtain the three-dimensional visual operation and maintenance graphics required for rail transit.

[0063] In the embodiment of the present invention, by comparing the signal times of the transportation vehicles in the entire rail transit, the communication path of the delayed vehicles is changed and switched, ensuring that the three-dimensional stereoscopic image of the entire transportation management can accurately reflect the current transportation situation, realize efficient management of transportation management, and reduce the delay of the entire rail transportation network.

[0069] 203. Convert the timestamps corresponding to all the location data in the location data set into binary numbers according to a preset coding algorithm;

[0070] 204. Compare and sort all binary numbers to obtain time sorting;

[0071] 205. Capture the binary data at both ends of the time sorting, determine the sizes of the two binary data, determine the larger binary data as the maximum timestamp, and determine the smaller binary data as the minimum timestamp;

[0072] In embodiments 203-205, the date in the format of XXXX.XX.XX XX:XX:XX:XX is converted into binary data, and then the binary data is sorted by size to obtain the sorting size of the time, the smallest sorting value is determined as the minimum timestamp, and the largest sorting value is determined as the maximum timestamp.

[0073] 206. Determine whether the difference between the maximum timestamp and the minimum timestamp is greater than a preset time threshold;

[0074] This embodiment is similar to the first embodiment. Please refer to the first embodiment and will not be described in detail here.

[0075] 207. If it is greater than the time threshold, a test signal is sent to a calibration vehicle among the N vehicles to obtain a feedback duration;

[0076] 208. Determine whether the feedback duration is less than a preset transmission threshold;

[0077] 209. If it is less than the transmission threshold, the timestamp corresponding to the position data of the calibrated vehicle is determined as the test timestamp;

[0078] In embodiments 207-209, a test signal is sent and a test feedback signal is received to determine whether there is a vehicle with a normal transmission time. If the transmission time is less than the transmission threshold, the vehicle is deemed to be a normally working device, and based on the normal device, the vehicle is used as a standard comparison device to compare and judge the remaining N-1 vehicles.

[0079] 210. Perform absolute value processing on the difference between the test timestamp and the timestamps corresponding to all the position data to obtain N-1 time differences;

[0080] 211. Determine in sequence whether the time difference is less than a preset qualified threshold;

[0081] 212. If the time difference is less than the qualified threshold, the position data corresponding to the time difference is determined as not needing to be changed;

[0082] 213. If it is greater than the qualified threshold, the position data corresponding to the time difference is determined to be to be changed;

[0083] In embodiments 210-213, the timestamps corresponding to the location data of standard normal vehicles are subtracted from those of other vehicles. After obtaining the numerical value, the time difference is compared with the qualified threshold of 50ms, and the signal transmission of the entire system is adjusted to reduce the delay error of the entire system.

[0084] 214. Modify the communication transmission paths corresponding to all the position data to be modified to obtain new communication transmission paths of the vehicles corresponding to all the position data to be modified;

[0085] 215. Re-acquire the location data of the vehicle;

[0086] In the 214-215 embodiments, the communication transmission path of the vehicle whose time exceeds the normal difference is adjusted, and after the adjustment is completed, the position data of the vehicle is re-acquired and re-detected and analyzed.

[0087] 216. If it is greater than the transmission threshold, remove the calibrated vehicle from the N vehicles, send the test signal to another calibrated vehicle from the N-1 vehicles, and obtain a new feedback duration;

[0088] In this embodiment, if the test data shows that the calibrated vehicle is an abnormal vehicle, a test signal is resent to another calibrated vehicle among the remaining N-1 vehicles, and a new judgment is made until the tested calibrated vehicle is determined to be communicating normally.

[0089] 217. If it is less than the time threshold, obtain the punctuation data of all preset sensors, and generate a punctuation matrix according to all the punctuation data;

[0090] 218. Establish a communication connection with the Unity platform system and send the punctuation matrix to the Unity platform system;

[0091] 219. Receive feedback data from the Unity platform system, and simulate the feedback data based on the plant simulation platform to obtain a three-dimensional visual operation and maintenance graphic of the rail transit.

[0092] In the embodiments 217-219, it is determined that there are no abnormal problems in the transmission data of N vehicles, and the current spatial position data captured by the sensor is written into the matrix according to the set coding sorting, and the punctuation matrix is ​​sent to the Unity platform to be rendered into a three-dimensional image. The three-dimensional image is then transmitted to the plant simulation platform for simulation rendering to obtain the required rail transit image data.
