Description of drawings
Figure of description is used to provide further understanding of the present invention, constitutes the application's a part, and illustrative examples of the present invention and explanation thereof are used to explain the present invention, do not constitute improper qualification of the present invention.In the accompanying drawings:
Fig. 1 is the flow chart according to the key step of the vehicle locking method of the engineering machinery of the embodiment of the invention; And
Fig. 2 is the schematic diagram according to the main modular of the locking system of the engineering machinery of the embodiment of the invention.
The specific embodiment
Need to prove that under the situation of not conflicting, embodiment and the feature among the embodiment among the application can make up mutually.Describe the present invention below with reference to the accompanying drawings and in conjunction with the embodiments in detail.
Fig. 1 is the flow chart according to the key step of the vehicle locking method of the engineering machinery of the embodiment of the invention, and as shown in Figure 1, this method mainly comprises the steps:
Step S11: the engineering machinery that is in released state is accepted the operation of Telelock car;
Step S13:, and keep engineering machinery to be in released state according to lock car operation note lock car identification information;
Step S15: when the next startup of engineering machinery powers on, confirm to have write down lock car identification information;
Step S17: engineering machinery is placed lock-out state.
The operation of Telelock car can be to be sent by long-range control centre.From above flow process as can be seen, after receiving the operation of Telelock car, immediately engineering machinery is not locked, but be locked when powering in engineering machinery startup next time, be the unexpected locked accident that may bring or other negative consequences thereby can avoid at engineer machinery operation.
Engineering machinery can be to receive a release information every the default time, and keep self being in released state according to this release information, like this, if desired engineering machinery is locked the car operation, only need stop to send described release information and get final product to engineering machinery.
In addition, the time can be to send lock car information locking the car operation to engineering machinery, this lock car information can be anyly not to be complementary in the information of unlocking pin.Because unlocking pin is to be provided by long-range control centre, so remote control center can guarantee to lock car information and not be complementary in unlocking pin.After engineering machinery is received lock car information, confirm that the content of lock car information is not complementary in the unlocking pin of self preservation, then record lock car identification information.A kind of simple form that unlocking pin and release information are complementary is that the two is complementary.Can certainly adopt other matched form.
