Abstract
The invention discloses a kind of timing vehicle-locking method of engineering truck, described engineering truck is provided with GPS module, described GPS module to be connected with phase inverter by monostable sequential decoding circuit provides car locking control signal, wherein, when described timing vehicle-locking method comprises the steps: car locking, described GPS module first sends a negative going pulse, and sends negative going pulse at the appointed time continuously and realize car locking to the input end of monostable sequential decoding circuit; During unblock, GPS device first sends negative going pulse, and after transmission negative going pulse, sends negative going pulse continuously and realizes unlocking being less than in specified time.The timing vehicle-locking method of engineering truck provided by the invention, replaces existing set or reset mode by time sequential pulse, improves confidentiality and safety performance, is difficult to crack and is easy to use.
Description
Technical field
The present invention relates to a kind of engineering truck vehicle locking method, particularly relate to a kind of timing vehicle-locking method of engineering truck.
Background technology
In order to realize remote scheduling and control better, GPS (GlobalPositioningSystem, global positioning system) has become construction machinery and equipment to dispatch from the factory one of standard configuration part.GPS is mainly used in Long-distance Control and data acquisition occasion, and the work information in real time for vehicle gathers, and is back to central server by wireless signal is long-range, is conducive to Collection and analysis vehicle real-time status, understands vehicle performance., monitor in real time for violation operation machinery or the lower user of refund credit rating meanwhile, long-range car locking or unlocking function can be realized in situation necessarily.
Existing long-range car locking or unblock realize mainly through set or reset mode, and confidentiality is not high, and cracker can analyze whole system by the state of control bit, thus cracks car locking.Therefore, be necessary to improve existing engineering truck vehicle locking method, improve confidentiality and safety performance, be difficult to crack and be easy to use.
Summary of the invention
Technical matters to be solved by this invention is to provide a kind of timing vehicle-locking method of engineering truck, improves confidentiality and safety performance, is difficult to crack and is easy to use.
The present invention solves the problems of the technologies described above the timing vehicle-locking method that the technical scheme adopted is to provide a kind of engineering truck, described engineering truck is provided with GPS module, described GPS module to be connected with phase inverter by monostable sequential decoding circuit provides car locking control signal, wherein, when described timing vehicle-locking method comprises the steps: car locking, described GPS module first sends a negative going pulse, and send the input end of negative going pulse to monostable sequential decoding circuit continuously at the appointed time, if monostable sequential decoding circuit receives pulse at the appointed time continuously, it exports and keeps SM set mode to realize car locking, during unblock, GPS device first sends negative going pulse, and after transmission negative going pulse, and send negative going pulse continuously being less than in specified time, if monostable sequential decoding circuit receives pulse at the appointed time continuously, it exports and keeps SM set mode to realize unlocking.
The present invention contrasts prior art following beneficial effect: the timing vehicle-locking method of engineering truck provided by the invention, replaces existing set or reset mode by time sequential pulse, improves confidentiality and safety performance, is difficult to crack and is easy to use.

Detailed description of the invention
Below in conjunction with drawings and Examples, the invention will be further described.
Fig. 1 is the sequential car locking circuitry block schematic diagram of engineering truck of the present invention; Fig. 2 is the sequential car locking schematic flow sheet of engineering truck of the present invention.
Refer to Fig. 1 and Fig. 2, the timing vehicle-locking method of engineering truck provided by the invention, described engineering truck is provided with GPS module 1, and GPS module 1 to be connected with phase inverter 3 by monostable sequential decoding circuit 2 provides car locking control signal, wherein, described timing vehicle-locking method comprises the steps:
Monostable sequential decoding circuit and input end are after receiving a negative going pulse, its mouth set, and again must receive pulse (this time is determined by monostable sequential circuit) at the appointed time, circuit exports just can keep SM set mode, and because the phase inverter 3 after monostable sequential circuit acts on, control end is reset mode, car unlocks, otherwise circuit exports and forwards reset mode to, under the effect of phase inverter 3, car locking.
Vehicle is by after GPS module 1 car locking, and want to unlock, GPS module 1 must send negative going pulse, and after transmission negative going pulse, again must send negative going pulse being less than in specified time, and reciprocal with this, engineering truck just can be in released state, otherwise engineering truck will be in car locking state again.
In sum, the timing vehicle-locking method of engineering truck provided by the invention, replaces existing set or reset mode by time sequential pulse, improves confidentiality and safety performance, is difficult to crack and is easy to use.
Although the present invention discloses as above with preferred embodiment; so itself and be not used to limit the present invention, any those skilled in the art, without departing from the spirit and scope of the present invention; when doing a little amendment and perfect, therefore protection scope of the present invention is when being as the criterion of defining with claims.
Claims (1)
1. a timing vehicle-locking method for engineering truck, described engineering truck is provided with GPS module, and described GPS module to be connected with phase inverter by monostable sequential decoding circuit provides car locking control signal, and it is characterized in that, described timing vehicle-locking method comprises the steps:
During car locking, described GPS module first sends a negative going pulse, and send the input end of negative going pulse to monostable sequential decoding circuit continuously at the appointed time, if monostable sequential decoding circuit receives pulse at the appointed time continuously, it exports hold reset state and realizes car locking;
During unblock, GPS device first sends negative going pulse, and after transmission negative going pulse, sends negative going pulse continuously being less than in specified time, if monostable sequential decoding circuit receives pulse at the appointed time continuously, it exports and keeps SM set mode to realize unlocking, and due to the phase inverter effect after monostable sequential decoding circuit, control end is SM set mode, car unlocks, otherwise circuit exports and forwards reset mode to, under the effect of phase inverter, car locking.
