Detailed Description
The following description of the embodiments of the present invention will clearly and fully describe the technical aspects of the embodiments of the present invention, and it is apparent that the described embodiments are only some embodiments of the present invention, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the present invention without making any inventive effort, are intended to fall within the scope of the present invention.
The invention provides a vehicle transportation management method based on a vehicle-mounted terminal, which is shown in fig. 1 and comprises the following steps:
s1, after the dispatcher completes identity verification and identification, starting vehicle transportation, and recording position information at intervals by the vehicle-mounted terminal;
s2, after the transport vehicle arrives at the destination, the dispatcher performs authentication identification again to finish the transport of the vehicle;
s3, evaluating the performance of a dispatcher in the transportation of the vehicle according to the data recorded by the vehicle-mounted terminal, and giving an evaluation report; and analyzing problems in the vehicle transportation process according to the data recorded by the vehicle-mounted terminal, and modifying the vehicle-mounted terminal.
It should be noted that: the existing vehicle transportation management method generally comprises three links of vehicle dispatching, transportation and customer goods delivery for vehicle transportation management.
The dispatching of the dispatching vehicles is controlled by a dispatcher, and the dispatcher can assign and monitor the transportation tasks, assign and monitor the vehicles and monitor the cargoes according to the types of the transported cargoes, so that the management of the transportation of the vehicles is realized. The vehicle-mounted terminal completes identity verification and identification, is used for carrying out cargo handover links, and is used for acquiring the position information of the vehicle in real time when the vehicle is positioned, so that a dispatcher can monitor the travel of the vehicle conveniently, an abnormal alarm is assisted to an identity verification and identification model and a positioning model, and when the identity verification and identification do not pass or the position information is deviated, the abnormal alarm is used for warning.
However, in the conventional vehicle transportation management method, evaluation and correction are not performed on management personnel and a management system, so that two evaluation values are required to be set up to evaluate or correct the management personnel and the management system respectively, and the evaluation or correction conditions are combined to perform dual control on the personnel and the system for vehicle transportation management.

It should be noted that: acquiring the identity verification recognition accuracy, the positioning deviation rate and the alarming times of a dispatcher in the vehicle transportation process through a vehicle-mounted terminal, wherein the identity verification accuracy determines the careful degree of the dispatcher, and if the dispatcher is careful enough, the problem of identity verification by mistake does not occur; the positioning deviation rate is the degree of deviation of the vehicle from a given channel in the vehicle transportation process, and if the deviation is too large, the scheduler is not concerned with the vehicle transportation process at any time and plays the role of negligence; the number of alarming is the number of times of comprehensively reflecting the identification, the positioning and other problems, and the more the number of alarming is, the worse the capability of a dispatcher is.

It should be noted that: the identification accuracy alpha, the positioning deviation rate beta and the alarming times theta comprehensively reflect the capability of a dispatcher, but the alarming times comprehensively reflect the times of occurrence of a plurality of problems, so the occupied weight is not high; the positioning deviation rate and the identity verification accuracy are directly related to the degree that the dispatcher pays attention to the vehicle transportation process, so that the weight is high.
The weight coefficient of the preset identity authentication recognition accuracy, the weight coefficient of the positioning deviation rate and the weight coefficient of the alarm times are respectively 0.4, 0.4 and 0.2.

After the respective variances are obtained, the vehicle-mounted terminal correction value is calculated by giving weight to the variances,
here three sample data are taken, authentication identification data a 1 、a 2 、a 3 Positioning data b 1 、b 2 、b 3 Alarm data c 1 、c 2 、c 3 . After the variances of the identification verification data, the positioning data and the alarm data are obtained, the larger the variances are, the worse the stability of the data is, and the lower the adaptation degree of the vehicle-mounted terminal is.
Because the identity verification data usually verifies the identity, the problem is generally avoided, and the weight is low; positioning data often goes wrong and has larger weight; the alarm data are various, so that larger fluctuation occurs, and the weight is minimum.
The weight coefficient of the preset identity authentication identification data, the weight coefficient of the positioning data and the weight coefficient of the alarm data are respectively 0.2, 0.7 and 0.1.

Providing a dispatcher capability evaluation report according to a dispatcher capability evaluation result, setting a recommended value, wherein the recommended value of a dispatcher with excellent capability is highest, namely the higher the dispatcher evaluation value is, the higher the recommended value is, and the recommended value is used for assigning the dispatcher to make a reference; and the disqualified dispatcher does not recommend the disqualified dispatcher, and a simulation test is required to be carried out to acquire a qualified capability assessment report.
Step S32 includes:
s321, the smaller the correction value of the vehicle-mounted terminal is, the higher the adaptation degree of the vehicle-mounted terminal is; the larger the correction value of the vehicle-mounted terminal is, the lower the adaptation degree of the vehicle-mounted terminal is;
s322, analyzing problems of identity verification and identification, vehicle positioning and abnormality alarming in the vehicle transportation process, modifying the functions of the vehicle-mounted terminal, namely the identity verification and identification, the vehicle positioning and the abnormality alarming, and adding other functions to compensate other problems in the vehicle transportation process.
It should be noted that: when the correction value of the vehicle-mounted terminal is smaller than or equal to 0.25, the vehicle-mounted terminal is qualified in adaptation, and when the correction value of the vehicle-mounted terminal is smaller than or equal to 0.01, the vehicle-mounted terminal is excellent in adaptation; and when the correction value of the vehicle-mounted terminal is greater than 0.25, the vehicle-mounted terminal is unqualified.
