In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
A work machine control method according to an embodiment of the present invention will be described below with reference to fig. 1 to 3.
The embodiment of the invention provides a working machine control method which can be applied to a remote information processor. The telematics BOX (T-BOX for short) is mainly used for communicating with a background system and an intelligent terminal. The working machine includes: cranes, excavators, loaders, etc. The specific implementation of the method is shown in fig. 1:
Wherein, the terminal includes intelligent terminal or communication terminal etc. and intelligent terminal includes: cell-phone, computer, smart machine such as dull and stereotyped, communication terminal includes: relay devices, base stations, etc. In the following, a terminal is taken as an example for description, but it should be noted that the description is only an example and is not intended to limit the scope of protection.
The T-BOX can also receive a request control instruction sent by the cloud server, specifically, the intelligent terminal sends the request control instruction to the cloud server through networks such as 4G, 5G or WIFI, and the cloud server sends the request control instruction to the T-BOX.
The cloud server is used as a medium for wireless transmission of the intelligent terminal and the T-BOX, and the intelligent terminal is combined with 4G/5G communication to realize the low-delay accurate control of the intelligent terminal on the operation machine.
Specifically, when the smart terminal wants to Control the work machine, it needs to wake up a plurality of Electronic Control Units (ECUs) in the work machine. The internal network of the work machine according to the present invention manages the network by using the OSEK. The OSEK is a standard applied to modules and static real-time operating systems, and is intended to establish a standardized interface for automotive electronics.
Since the smart device does not always remotely control the work machine, and in addition, in order to ensure that the load factor of the internal network of the work machine is at a low level, when the work machine is controlled by the smart device, the request control command, the execution control command and the like sent by the smart terminal received by the T-BOX are all event type messages, that is, when the work machine is controlled by the smart terminal, the request control command or the execution control command is sent at a preset cycle and a preset number of times. Therefore, only when the operation machine is controlled through the intelligent terminal, the bus resources are occupied, wherein the bus resources are CAN bus resources.
The schematic diagram of the event type message can be seen in fig. 2, the messages triggered by different events are not affected, and the event type message is sent in a preset period and preset times and is stopped. In fig. 2, a blank box represents an event a, a box with oblique lines represents an event B, and it should be noted that this is only an example and a distinction, and does not have other meanings.

And after the verification code is returned to the terminal, waiting for receiving a second verification code sent by the terminal. After receiving the second check code, determining whether the first check code and the second check code are successfully matched, and returning first response information to the terminal when determining that the first check code and the second check code are successfully matched; when it is determined that the first check code and the second check code fail to match, no message is returned to the terminal, that is, the terminal cannot control the work machine.
Specifically, there are various ways to determine that the first check code and the second check code are successfully matched, for example, when the first check code and the second check code are consistent, it is determined that the first check code and the second check code are successfully matched; for another example, the first check code and the second check code may be combined, and when it is determined that the combination result is consistent with the preset combination, it is determined that the first check code and the second check code are successfully matched; and the like.
Of course, the first response message may also be used to indicate that the work machine is capable of being controlled by the smart terminal, or to indicate that the work machine is not capable of being controlled by the smart terminal. When the first check code and the second check code are determined to be successfully matched, returning first response information indicating that the working machine can be controlled by the intelligent terminal to the intelligent terminal; when it is determined that the first check code and the second check code fail to match, first response information indicating that the work machine cannot be controlled by the intelligent terminal is returned to the intelligent terminal.
