where r is the earth radius.

When D exceeds a set distance threshold X (usually 15 meters), namely D > X, the new point location data is considered to be problematic, and the reverse is normal; when abnormal points occur once, the vehicle abnormal marks are accumulated 1, when the accumulated value of the vehicle abnormal marks exceeds a set constant E, the vehicle is marked to be in a vehicle-mounted cold start state, the vehicle personnel association calculation is not participated, after the duration exceeds the set time, the marks are removed, and the latest point position data are put in again; when the vehicle point data is lost, the corresponding vehicle data loss marks are accumulated by 1, and after the data loss marks exceed a set constant H (usually taken 5 times), the vehicle is removed from the vehicle dynamic list;

when the vehicle position is updated, the point position data which is originally to be replaced and updated is stored in a vehicle track data list, and the updated time of the point set is recorded and used as a historical data point set for subsequent calculation.

When the server processing module updates the state of the first-line staff, a mode of calculating the distance of the point line is adopted, specifically:

after the latest personnel position point location data (ppx 1, ppy 1) are acquired, the vehicle list is traversed in sequence according to the personnel position point location data time stamp t, point set data (S is a set constant parameter and can be adjusted, usually 20 seconds) of each vehicle from t+S to t-S are acquired, and the acquired point set data of each vehicle are recorded as:

continuing to judge, and when the subsequent continuous judgment state mark exceeds a set constant A (usually 5), considering that the corresponding person is associated with the vehicle;

if the distance between the corresponding vehicle and the person is judged to be greater than a constant Y after the record of the relationship between the vehicle and the person is generated, the negative sign of the association between the vehicle and the person is accumulated by 1, and when the negative sign exceeds a set constant B (usually 5 is taken), the association between the vehicle and the person is considered to be absent, and the record is deleted.

In the field implementation and application process of an airport, the invention relies on a passenger elevator car to install a high-precision vehicle-mounted positioning facility, and provides a vehicle-mounted return data communication network, and the vehicle-mounted positioning facility has the problem of inaccurate positioning in the cold starting process and temporary shielding process of the facility because of the technical characteristics, so that the invention has a related positioning data filtering processing means.

The invention also relies on handheld terminal equipment of first-line operators, in most airports, the passenger elevator car operators can ensure one handheld terminal of the personnel, the handheld terminal is provided with a multidimensional Android operating system, a positioning acquisition program is installed in the handheld terminal, because the positioning, acquisition and return all consume limited electric quantity of the handheld terminal, in actual processing, the data acquisition frequency is reduced, and meanwhile, the data return is carried out by adopting a bottom tcp custom binary protocol, so that the electric quantity consumption is reduced as much as possible, and the positioning data processing is similar to the vehicle-mounted terminal equipment.

The invention has the advantages that a large number of logic judgment calculations depend on direct memory operation, the processing speed is relatively high, in order to ensure that the application does not occupy too much memory, the outdated data is deleted according to the processing logic in time, and in order to reduce the CPU occupation consumption, the related setting constant parameters can be adjusted on the processing logic, so that the calculation times and the calculation data range are smaller, and the overall processing speed is improved.

In the actual apron working site, different workers and different types of operation passenger vehicles, because of different business types, different personnel operation habits and different busyness, a plurality of site different scenes can appear, the invention takes the site different scenes into consideration as much as possible, but in the actual production application, a test and parameter adjustment process is also needed, and parameters are continuously adjusted, so that the passenger-elevator vehicle association relationship judged by the invention is more accurate.

The foregoing is only a preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art, who is within the scope of the present invention, should make equivalent substitutions or modifications according to the technical scheme of the present invention and the inventive concept thereof, and should be covered by the scope of the present invention.
