Embodiment Construction
[0037] The present invention will be further described below in conjunction with accompanying drawing:
[0038] A kind of multi-sensor fusion-based cableway cable car ranging alarm method according to the present invention, the steps are as follows figure 2 Shown:
[0039] Step 1, installing sensors on each funicular;
[0040] Step 2, collect the latitude and longitude, altitude and three-axis acceleration of each cable car in real time through the sensor;
[0041] Step 3, judging the validity of the collected cable car data, discarding if the data is invalid, and processing the data if the data is valid;
[0042] Step 3-1, three-dimensional coordinates (lon, lat, alt) formed by the longitude, latitude and altitude data collected during the one-week operation of the cable car along the cableway line, that is, (longitude, latitude, altitude) to draw the cable car operation line map;
[0043]Step 3-2, using the route map as a reference, judge whether the cable car is in the ...

The invention discloses a cableway cable car distance measurement and alarm method and device based on multi-sensor fusion. According to the method, through multi-sensor data real-time calculation, whether an adjacent cable car runs in a safe operation range is judged, the real-time alarm is carried out when a cable car distance is too close, and false alarm conditions caused by tourist on and off at a station and GPS drift are filtered. The device is formed by a data acquisition and transmission module, a data processing module and a monitor module. The data acquisition and transmission module is installed in a car of a cable car and collects various data of the cable car and transmits the data to the data processing module through wireless network transmission. The data processing module processes the received data, displays the operation of the cable car to a supervisor in real time, and carries out an alarm when the adjacent cable car is too close. According to the method and the device, the processing can be timely and effectively carried out in case of accidents, misreporting and false reporting phenomena are avoided, the distance between cable cars can be rapidly judged in real time, and thus the supervisor timely finds and processes the accidents.
Description
technical field [0001] The invention relates to the field of cable car operation safety, in particular to a cable car ranging alarm algorithm and device. Background technique [0002] Cableway cable car is a transportation method in which electric energy is used as the power to pull passenger vehicles by steel cables on the line with overhead steel cables as the track. In recent years, cableway accidents at home and abroad have appeared in the newspapers from time to time. Analyzing the reasons, many of these accidents are caused by not being discovered in time because the distance between the cable cars is close. [0003] The current cableway products generally pay attention to the consideration of mechanical equipment, adopt anti-slip rope devices or protective devices, and carry out regular inspections of mechanical equipment. But can only report to the police after the accident for reporting to the police, can not reach the requirement of real-time monitoring cable car...
