Comprise in the structure of the second above-mentioned protective circuit: the inductance coil L1 and the sustained diode 1 that is connected in parallel on inductance coil L1 two ends that are serially connected in the power input of engine oil door controller 1.
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 CPU indicating relay action in the long-distance monitorng device then; The contact of relay breaks off the path of normal operation, and reaches the purpose of lock car.What send instruction to CPU can be the tele-control system away from construction machinery and equipment, also can be through the coding of in advance CPU being set, through the incompatible realization of action group of manipulator throttle and work operative bar certain rule.
Fig. 1 shows is that two contacts of a pair of normally closed interlock Jl-l of relay switching circuit 4A are serially connected in manipulator throttle 2 and give the 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, 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 switch on to relay coil; Break off above-mentioned normally closed interlock Jl-l; Connect two contacts of normally open contact Jl-2, then the constant potential of divider resistance is caused engine oil door controller 1, thus make driving engine constant under a rotating speed.Through 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 the second relay switching circuit 4B is serially connected in key switch circuit 3 and gives the 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, other end ground connection.Under normal circumstances, behind the engine starting, key switch provides a stable voltage signal for engine oil door controller 1; And at lock during car, the CPU of long-distance monitorng device receives the instruction that the tele-control system of construction machinery and equipment sends, and will switch on to relay coil; Break off 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; Think that the driver has turned off key switch, the throttle motor action of control driving engine is with engine off; Behind engine off, CPU also disappears for the signal voltage of relay coil J2 thereupon, and the normally closed interlock J2-1 of relay coil J2 is closed; 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 coil J2 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.From Fig. 1, can see between manipulator throttle circuit 2 and CPU, also having a signal connecting line, it is input to the voltage signal of manipulator throttle circuit 2 among the CPU, locks car.Manipulator throttle circuit 2 is adjustable resistance R3; Change through the size that changes resistance and to give the engine oil door controller 1 voltage signal; The signal voltage of each gear output of manipulator throttle circuit 2 is fixed; When manipulator throttle circuit gear during, will export the voltage signal of regular variation according to the certain rule conversion.The signal voltage of exporting respectively like 1,2,3 gears of manipulator throttle circuit is A, B, C volt, then manipulator throttle circuit 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 manipulator Oil Switch in certain sequence; Manipulator throttle circuit 2 will send voltage signal to CPU through signal connecting line, 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 manipulator throttle circuit 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 was broken off, 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 manipulator throttle Circuit 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 with to lock car the same.
In the utility model, CPU adopts the 80C196 chip, also can adopt the chip of other models.
