Description of drawings

Fig. 1 is the structural representation of the utility model manual accelerator lock car part;

Fig. 2 is the structural representation of the utility model key switch lock car part;

The specific embodiment

The utility model is a kind of vehicle remote control monitor unit that has increased multiple lock car function.Its design concept is that the contact with relay is serially connected in the engine oil door controller of machinery and sends between the parts of throttle control signal instruction, utilize the central processor CPU indicating relay action in the long-distance monitorng device then, the contact of relay disconnects the path of normal operation, and reaches the purpose of lock car.At this, what send instruction to central processor CPU can be tele-control system away from construction machinery and equipment, also can be by the coding of in advance CPU being set, by the incompatible realization of action group of manual accelerator and work operative bar certain rule.

Fig. 1 shows is that two contact A, the B of a pair of normally closed interlock J1-1 of relay J 1 are serially connected in manipulator throttle 2 and give situation in the circuit that engine oil door controller 1 carries voltage signal.The P2.5 signal output part of the CPU of the coil one termination long-distance monitorng device of relay J 1, other end ground connection.When the CPU of long-distance monitorng device receives the instruction that the tele-control system of construction machinery and equipment sends, will give relay J 1 coil electricity, disconnect above-mentioned normally closed interlock J1-1, connect two contact A, the C of normally open contact J1-2, so the constant potential of divider resistance is caused the engine oil door controller, thereby makes driving engine constant under a rotating speed.By selecting the divider resistance of different resistances, can engine speed is constant in idling mode, claim that this lock car state is an one-level lock car.

Fig. 2 shows is that a pair of normally closed interlock J2-1 of relay J 2 is serially connected in key switch 3 and gives situation in the circuit that engine oil door controller 1 carries voltage signal.The P2.7 signal output port of the CPU of the coil one termination long-distance monitorng device of relay J 2, other end ground connection.Under normal circumstances, behind the engine starting, key switch 3 provides a stable voltage signal for engine oil door controller 1 always, and when the lock car, the CPU of long-distance monitorng device receives the instruction that the tele-control system of construction machinery and equipment sends, will give relay J 2 coil electricities, disconnect this a pair of normally closed interlock J2-1, open-circuit line, engine oil door controller 1 detects the key switch output voltage by high step-down like this, thinks that the driver has turned off key switch, the throttle motor action of control driving engine, with engine off, behind engine off, CPU also disappears for the signal voltage of relay J 2 thereupon, the normally closed interlock J2-1 closure of relay J 2, driving engine starts once more, and CPU detects the instruction of lock car does not have releasing will send the normally closed interlock J2-1 disconnection that instruction makes relay J 2 once more, and driving engine is flame-out once more.Driving engine is in and just starts and will stop working like this, and state that can't normal operation is called the secondary latch car.

The structure that shows among Fig. 1,2 makes the CPU of long-distance monitorng device implement can also carry out the manual lock car the lock car except the instruction that the tele-control system that can be used for by construction machinery and equipment sends.Also have a signal connecting line 4 as can see from Figure 1 between manual accelerator 2 and CPU, it is input to the voltage signal of manual accelerator 2 among the CPU, locks car.Manipulator throttle 2 is adjustable resistances, change by the size that changes resistance and to give the engine oil door controller 1 voltage signal, the signal voltage of each gear output of manual accelerator 2 is fixed, and when manual accelerator gear during according to the certain rule conversion, will export the voltage signal of regular variation.The signal voltage of exporting respectively as 1,2,3 gears of manual accelerator is A, B, C volt, then manual accelerator is stirred according to the 2-3-1 order and will be exported continuous B-C-A volt voltage signal.Therefore, the voltage signal that can select above-mentioned variation is input to as lock car password in the middle of the CPU, and the voltage signal that different rules change can be distinguished corresponding one-level lock car and secondary latch car.When needs lock car, can stir the manual accelerator switch in certain sequence, manual accelerator 2 will send voltage signal to CPU by signal connecting line 4, and CPU can control different lock car relays respectively according to the cooresponding lock car of detected voltage signal rank and realize locking car.

Except utilizing manual accelerator to carry out the manual lock car, can also utilize PPC (guide's oil circuit) pressure switch to lock car.When the PPC pressure switch is connected, fixing signal voltage is arranged in this circuit, signal voltage disappeared when the PPC pressure switch disconnected, when switching rule changes, and the also regular thereupon variation of signal voltage.When handling joystick regularly, the PPC pressure switch is with disconnection, the closure of its rule.Therefore, can carry out the lock car of PPC pressure switch according to the method for above-mentioned manual accelerator lock car.Equally, with the signal voltage of the variation in the PPC pressure switch as lock car password setting in CPU, again signal connecting line is connected PPC pressure switch and CPU.When joystick changed in certain sequence, CPU will control different lock car relays respectively and realize locking car according to the cooresponding lock car of detected voltage signal rank.

Behind the manual lock car, recover normal operation as making machinery, also will carry out long-range or manually separate car, its principle is not being given unnecessary details with to lock car the same.

In the utility model, CPU adopts the 80C196 chip, also can adopt the chip of other models.
