Service apparatus for fleet management

Abstract

The invention provides a service apparatus for fleet management. The service apparatus comprises a wireless terminal and a client server and also comprises a medi-switching server for connecting the wireless terminal device and the client server, wherein the wireless terminal device consists of an on-vehicle unit and a dispatching screen, the on-vehicle unit comprises a microcontroller, an action communication module, a GPS module, a module communication interface and a communication port; the dispatching screen comprises a microcontroller, a display, a push-button module and a communication port. The medi-switching server is a server group consisting of a load balance server, an application server, a data base and an over-the-air (OTA) upgrading server and is used for the information intercommunication between the client server and the wireless terminal device and for upgrading parts or whole of the program codes of the wireless terminal device through the OTA. By adopting the invention, users can complete disposition of a desired fleet management system rapidly.

Description

technical field [0001] The present invention relates to a service device, and more particularly, to a service device for fleet management. Background technique [0002] Most of the current fleet management systems use wireless terminal devices to directly exchange information with the client server. Different users have different functions and needs, so the application software or map software developed on the client server is also very different. Therefore, when establishing a fleet management system, it is necessary to modify the program code of the wireless terminal device according to the needs of different users, resulting in the simultaneous modification of the front-end equipment and the back-end system, which greatly increases the time and cost required for construction. In addition, in the update and maintenance of the program code of the wireless terminal device, only one-to-one update can be performed in a wired manner, and the maintenance and operation of the act...

AI Technical Summary

Problems solved by technology

Some systems use short messages (SMS) to transmit information, but because the cost is too expensive and the delay time of short messages is difficult to grasp, the frequency of returning positioning information cannot be effectively improved

Some systems use the data function of circuit switch to transmit information. If the data connection is maintained all the time, the cost is expensive, and the voice call function must be discarded; if the quantitative information is accumulated and then transmitted online, the positioning data will lose its real-time performance.

[0004] It can be seen that there are still many deficiencies in the above-mentioned existing methods, which are not good designs and need to be improved urgently
