Description

Tear immediately lock machine implement device of machine open

One, technical field

The utility model relates to a kind of immediately lock machine implement device of machine of tearing open, particularly a kind of immediately lock machine implement device of the heartbeat machine of tearing open that order realizes with the lock car that utilizes.

Two, background technology

The degree of perfection of a urban public transport facility can reflect the degree of ripeness of its development of civilization and urban construction substantially, and fast easily traffic can solve many social concerns.In the U.S., design engineers are fused to location technology in the public bicycle leasing system, have manufactured experimently this information-based lease bicycle.The after-frame of this car has been installed intelligent cipher lock, and this lock is comprised of GPS position fixing system, electric locking and user profile treater.The user by oneself smart mobile phone or panel computer in gps system obtain from own nearest bicycle location information and lock password, in 15 minutes, it is ridden away after the reservation right to use, exceed the time then to preengage inefficacy.After you arrive the destination by bike, can continue to keep the right to use 15 minutes, also can allow immediately other people use.In addition, in order to improve the service efficiency of leasing system, this system also combines credit system, is late for giving back or does not lock that car then can be deducted the account credit score until nullify.

GPS logistics vehicles monitoring management system is the vehicle management system according at present logistic industry information system management demand exploitation, reach logistics vehicles and goods real time location tracking, thereby with the information of the owner of cargo in the carrier, shipping agency and each link of driver effectively, combine fully, reduce the empty wagons rate, car spotting to greatest extent, optimize enterprise's vehicle resources and control in real time the car operation situation, for Management of Modern Physical Distribution provides powerful actv. instrument, improve conveying efficiency, reduce traffic cost.

Accurately particular location, travel direction, the moving velocity of positioned vehicle---effectively scheduling ensures the intime freight transport destination;

As required, can have access to stroke, track record in the controlled vehicle 45 days---effectively analyze the allocation schedule vehicle;

By the GPS management and running, the long distance haulage vehicle reduces vehicle-mounted sky and sails, detours and travel---improve conveying efficiency;

The supervision vehicle, the statistics mileage, fuel oil takes few, and road toll has been lacked, expense is few at a high speed--save traffic cost;

The all mobile messages of controlled vehicle all are stored in control center's computing machine---and file in order, conveniently inquire about;

Effectively driving route, speed, parking site, the time of supervision vehicle---bus private, draw the energy of run goods controlled;

Remote operation, outage lock car, overspeed alarming---ensure chaufeur, goods, vehicle and client's property safety;

Show information of vehicles at electronic chart fast, near the vehicle checking is also dispatched---improve service quality, ustomer satisfaction;

Mileage, parking period, place, vehicular seat figure data is printed---the form that the convenient leader of making or vehicle management unit require.

The reasonableness of the consumption of oil mass and not―rationality and the supervision of volume read-out situation---vehicle fuel quantity is monitored, cut waste and the loss of the publicly-owned resource of system.

Three, summary of the invention

The problem that solves: need to solve in the prior art problem that can not the safety lock car.

Technical scheme:

As shown in Figure 1 and Figure 2, secondary lock vehicle device (201) is comprised of GPS/GPRS module (104), lock car module (101), vehicle ECU controller (102); GPS/GPRS module (104) and lock car module (101) are connected by CAN bus or spi bus or UART bus or LIN bus or self-defined bus; Lock car module (101) is by CAN bus or spi bus or UART bus or LIN bus or self-defined bus connection vehicle ECU controller (102); Vehicle ECU controller (102) connects vehicle motor (103);

Lock car module (101) sends and comprises two types order: heartbeat order, lock machine order;

The heartbeat order: lock car module (101) sends a string heartbeat data, thereby tells vehicle ECU controller (102), shows that lock car module (101) exists; Vehicle ECU controller (102) is within a period of time that receives the heartbeat order, the control vehicle is in normal working, when not receiving yet the heartbeat order above the time of setting, vehicle ECU controller (102) is locked car to driving engine, and driving engine is walked lamely;

The lock machine order: lock car module (101) sends a claw data lock machine order, when vehicle ECU controller (102) receives the lock car order of lock car module (101), vehicle ECU controller (102) is locked car to driving engine, and driving engine is walked lamely.

Restarting lock car implementation method:

The T1 pitch time; The T2 pitch time sets by program setting or when dispatching from the factory;

(1) every a time period T1, lock car module (101) sends a heartbeat order to vehicle ECU controller (102); The effect of heartbeat order is: every the T1 time, a heartbeat order is received in vehicle ECU control (102); Vehicle ECU controller (102) knows that lock car module (101) exists; Vehicle ECU controller (102) is not locked car;

(2) when vehicle ECU controller (102), still can not receive over time the heartbeat order behind the T1, vehicle ECU controller (102) sends orders immediately lock machine;

(3) after secondary lock vehicle device (201) receives the order of control platform (202) lock car, the lock car module (101) of secondary lock vehicle device (201) will lock that car information writes among the SRAM that locks car module (101), among the SDRAM, among the DDR, in FlashROM, EEPROM or the ferroelectric memory;

(4) after the vehicle motor ACC outage (closing vehicle motor), lock car module (101) beginning timing, when vehicle killed engine above T2 during the time, write down state that engine cutoff surpasses T2 in the SRAM of lock car module (101), among the SDRAM, among the DDR, in FlashROM, EEPROM or the ferroelectric memory;

(5) when vehicle starts again, among the SRAM of lock car module (101), among the SDRAM, among the DDR, in FlashROM, EEPROM or the ferroelectric memory lock car mark is arranged; And among the SRAM of lock car module (101), among the SDRAM, among the DDR, when having vehicle to kill engine above the T2 time tag in FlashROM, EEPROM or the ferroelectric memory; Lock car module (101) sends the order of lock car immediately, and control vehicle ECU controller (102) makes vehicle motor (103) be in the limping state; Vehicle can't normally be travelled.

Be illustrated in figure 2 as secondary lock vehicle device and control platform functional block diagram, by secondary lock vehicle device (201), control platform (202) two parts form; Secondary lock vehicle device (201) communicates with controlling between the platform (202) by GPRS or CDMA2000 or WCDMA or TD-SCDMA or LTE or WiFi or WiMAX or WiGig (gigabit wireless network).

Control platform (202) produces vehicle-locking signal automatically according to user's circumstances of tenancy and refund situation, and sends secondary lock vehicle device (201) to by GPRS or CDMA2000 or WCDMA or TD-SCDMA or LTE or WiFi or WiMAX or WiGig.

Beneficial effect: utilize secondary lock car to confirm, solve in the prior art, problem that can not the safety lock car.
