It should be noted, however, that the numerous details set forth in the description are merely for the purpose of providing the reader with a thorough understanding of one or more aspects of the present invention, which may be practiced without these specific details.
As used in this application, the terms "module," "system," and the like are intended to include a computer-related entity, such as but not limited to hardware, firmware, a combination of hardware and software, or software in execution. For example, a module may be, but is not limited to: a process running on a processor, an object, an executable, a thread of execution, a program, and/or a computer. For example, an application running on a computing device and the computing device may both be a module. One or more modules may reside within a process and/or thread of execution and a module may be localized on one computer and/or distributed between two or more computers.
The inventors of the present invention have noted that remote management of vehicles has been widely used in the fields of public security, medical treatment, fire protection, transportation, logistics, and the like. A vehicle dispatch system comprising: the system comprises a passenger mobile terminal, a dispatching server and a taxi mobile terminal; the three parts communicate through a wireless mobile network. The method for dispatching the vehicles by the system specifically comprises the following steps: the passenger mobile terminal carries the requirements input by the user on the scheduling request message for wireless transmission; the dispatching server screens out taxis meeting the conditions according to the user requirements in the dispatching request message, and sends a request confirmation message to a taxi mobile terminal on the taxi; and if the confirmation message returned by the taxi mobile terminal is received, the voice connection between the taxi mobile terminal and the passenger mobile terminal is established.

S404: after analyzing the identifier of the vehicle-mounted terminal 202 from the received scheduling information acquisition request, the agricultural machinery management platform 201 searches the identifier of the farmland to be operated, the planting information, the water, fertilizer and pesticide management information and the operation type information corresponding to the identifier of the vehicle-mounted terminal from the database server 222, and returns the information to the vehicle-mounted terminal in response to the information carried in the response.
Specifically, after receiving a scheduling information acquisition request sent by the vehicle-mounted terminal 202 through a communication network, the vehicle-mounted terminal server 221 of the agricultural machinery management platform 201 analyzes an identifier of the vehicle-mounted terminal 202 from the scheduling information acquisition request; the identification of the farmland to be worked, planting information, water, fertilizer and pesticide management information and the work type information corresponding to the identification of the vehicle-mounted terminal are searched from the database server 222, and are carried in response information and returned to the vehicle-mounted terminal through the communication network.
Preferably, after the vehicle-mounted terminal server 221 analyzes the identifier of the vehicle-mounted terminal 202, the farmland map data and the driving route corresponding to the identifier of the vehicle-mounted terminal 202 are also searched from the database server 222; and carrying the searched farmland map data, the driving route and the searched identification of the farmland to be operated in response information, and returning the data and the driving route to the vehicle-mounted terminal through a communication network.
S405: the in-vehicle terminal 202 displays or plays the scheduling information according to the returned response information.
Specifically, after receiving the response information sent by the vehicle-mounted terminal server 221 of the agricultural machinery management platform 201 through the communication network, the vehicle-mounted terminal 202 analyzes the identifier of the farmland to be operated from the response information, and then determines the position of the farmland with the identifier to display or play.
Preferably, the vehicle-mounted terminal 202 analyzes the identifier of the farmland to be operated from the response information, and also analyzes farmland map data and a driving route; and displaying a map according to the analyzed farmland map data, and highlighting and displaying the analyzed driving route, the farmland to be operated and the current position of the vehicle-mounted terminal in the map. The driver of the agricultural machine can drive the agricultural machine to smoothly reach the farmland to be operated according to the driving route in the map, so that the problems of wrong driving route of the agricultural machine, far-way detour, road asking by the driver and the like can be avoided, the time spent by the agricultural machine on the road can be reduced, and the use efficiency of the agricultural machine can be improved.
Preferably, the vehicle-mounted terminal 202 can further analyze planting information, water, fertilizer and pesticide management information and operation type information of a farmland to be operated from the received response information; and displaying planting information, water, fertilizer and pesticide management information and operation type information of the farmland corresponding to the farmland to be operated in the displayed map. The agricultural machinery driver can operate according to the displayed information, blind operation is avoided, and the utilization rate and the use efficiency of agricultural machinery and agricultural resources are improved.
According to the technical scheme, the vehicle-mounted terminals on the agricultural machines periodically and uniformly store information such as current positions and the like in an agricultural machine management platform; a manager of the agricultural machine can acquire information of each agricultural machine managed by the manager and each farmland to be operated from the agricultural machine management platform through the agricultural machine scheduling terminal, and manage and schedule the agricultural machine according to the acquired information; is beneficial to reasonably configuring agricultural machinery and improving the use efficiency of agricultural machinery and agricultural resources.
Moreover, the agricultural machinery scheduling terminals are distributed everywhere and do not need to be arranged at the same place with the agricultural machinery management platform; managers in various regions do not need to concentrate on the agricultural machinery management platform, and can access the agricultural machinery management platform only through respective agricultural machinery scheduling terminals, so that the managers can manage respective agricultural machinery conveniently.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of the present invention, and these improvements and modifications should also be construed as the protection scope of the present invention.
