Abstract
The invention discloses a timing vehicle-locking method for an engineering truck. In the vehicle-locking method, a GPS (global positioning system) module is mounted on the engineering truck; the GPS module is connected with an inverter through a monostable timing decoding circuit for providing vehicle-locking control signals, wherein the timing vehicle-locking method comprises the following steps that in vehicle locking, the GPS module firstly sends a negative pulse, and continuously sends negative pulses to an input end of the monostable timing decoding circuit within scheduled time for realizing vehicle locking; and in vehicle unlocking, GSP equipment firstly sends a negative pulse, and continuously sends negative pulses within time shorter than the scheduled time for realizing unlocking. For the timing vehicle-locking method for the engineering truck, the timing pulse mode is used for replacing the existing setting or resetting method, so that the security and the safety performance are improved, and the method 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, relate in particular to a kind of sequential vehicle locking method of engineering truck.
Background technology
In order to realize remote scheduling and control better, GPS (Global Positioning System, global positioning system) has become construction machinery and equipment one of the standard configuration part that dispatches from the factory.GPS is mainly used in Long-distance Control and data acquisition occasion, gathers to the work information of vehicle in real time, and through the long-range central server that is back to of wireless signal, helps Collection and analysis vehicle real-time status, understands vehicle performance.Simultaneously, monitor in real time, can realize Telelock car or unlocking function under the situation necessarily to violation operation machinery or the lower user of refund credit rating.
Existing Telelock car or release mainly realize that through set or reset mode confidentiality is not high, and the cracker can analyze total system through the state of control bit, thereby cracks the lock car.Therefore, be necessary existing engineering truck vehicle locking method is improved, improve confidentiality and safety performance, be difficult to crack and be easy to and use.
Summary of the invention
Technical matters to be solved by this invention provides a kind of sequential 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 sequential vehicle locking method that the technical scheme that adopts provides a kind of engineering truck; The GPS module is installed on the said engineering truck; Said GPS module links to each other with phase inverter through monostable sequential decoding circuit provides lock car control signal, wherein, and when said sequential vehicle locking method comprises the steps: to lock car; Said GPS module is sent a negative going pulse earlier; And send the input end of negative going pulse at the appointed time continuously to monostable sequential decoding circuit, if monostable sequential decoding circuit is received pulse at the appointed time continuously, its output keeps SM set mode to realize the lock car; During release, GPS equipment sends negative going pulse earlier, and after negative going pulse of transmission, in less than specified time, sends negative going pulse continuously, if monostable sequential decoding circuit is received pulse at the appointed time continuously, its output keeps SM set mode realization release.
The present invention contrasts prior art has following beneficial effect: the sequential vehicle locking method of engineering truck provided by the invention, replace existing set or reset mode through time sequential pulse, and improve confidentiality and safety performance, be difficult to crack and be easy to and use.

The specific embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is done further description.
Fig. 1 is the sequential lock car circuit block diagram of engineering truck of the present invention; Fig. 2 is the sequential lock wagon flow journey scheme drawing of engineering truck of the present invention.
See also Fig. 1 and Fig. 2; The sequential vehicle locking method of engineering truck provided by the invention is equipped with GPS module 1 on the said engineering truck, GPS module 1 links to each other with phase inverter 3 through monostable sequential decoding circuit 2 provides lock car control signal; Wherein, said sequential vehicle locking method comprises the steps:
Monostable sequential decoding circuit be input end after receiving a negative going pulse, its mouth set, and must receive pulse (this time by monostable sequential circuit decision) at the appointed time once more; Circuit output just can keep SM set mode, because phase inverter 3 effects behind the monostable sequential circuit, control end is a reset mode; The car release; Otherwise circuit output forwards reset mode to, under the effect of phase inverter 3, and the lock car.
Vehicle wants release after being locked car by GPS module 1, and GPS module 1 must be sent negative going pulse; And it is after negative going pulse of transmission, must in less than specified time, send negative going pulse once more, and reciprocal with this; Engineering truck just can be in released state, otherwise engineering truck will be in lock car state once more.
In sum, the sequential vehicle locking method of engineering truck provided by the invention replaces existing set or reset mode through time sequential pulse, improves confidentiality and safety performance, is difficult to crack and is easy to use.
Though the present invention discloses as above with preferred embodiment; Right its is not that any those skilled in the art are not breaking away from the spirit and scope of the present invention in order to qualification the present invention; When can doing a little modification and perfect, so protection scope of the present invention is when being as the criterion with what claims defined.
Claims (1)
1. the sequential vehicle locking method of an engineering truck is equipped with the GPS module on the said engineering truck, and said GPS module links to each other with phase inverter through monostable sequential decoding circuit provides lock car control signal, it is characterized in that said sequential vehicle locking method comprises the steps:
During the lock car; Said GPS module is sent a negative going pulse earlier; And send the input end of negative going pulse at the appointed time continuously to monostable sequential decoding circuit, if monostable sequential decoding circuit is received pulse at the appointed time continuously, its output keeps SM set mode to realize the lock car;
