Abstract
The utility model discloses a gearbox control device capable of achieving downshift protection and bus communication, and belongs to an engineering machinery control device. The gearbox control device capable of achieving downshift protection and bus communication mainly comprises a gearbox controller, a gear selector, a gearbox speed change valve, a speed sensor and a GPS, wherein the gear selector, the gearbox speed change valve, the speed sensor and the GPS are respectively connected with the gearbox controller through a speed change control wire harness. According to the gearbox control device capable of achieving downshift protection and bus communication, on the original control logic basis, downshift protection logic is achieved through the gear selector and the speed sensor; protection and remote control of a gearbox are achieved through the GPS. The gearbox control device capable of achieving downshift protection and bus communication is mainly used for loading machines.
Description
Technical field
The utility model belongs to a kind of engineering machine control device, specifically, relate in particular to a kind of can downshift the controller of gear-boxes of protection and bus communication.
Background technique
The output control mode of gearbox control for loader, the main shift signal that is input to controller by handle, the break-make of the corresponding speed change valve of control gearbox, directly export target gear, and the control of this controller to gearbox, is that rigid line directly drives mode, can not remote control.At present, also do not have a can be according to the real-time speed of a motor vehicle of complete machine, downshift step by step, seamlessly transits gearbox internal gear, realizes the controller to gearbox protection and remote control.
Summary of the invention
Adopt manually-operable in order to solve gearbox control traditional in prior art, cannot realize the defect of remote control, the utility model provide a kind of can downshift protection and the controller of gear-boxes of bus communication.
The utility model is achieved through the following technical solutions:
A kind of can downshift the controller of gear-boxes of protection and bus communication; comprise gearbox control, gear selector, gearbox speed change valve, velocity transducer and GPS navigation system, gear selector, gearbox speed change valve, velocity transducer and GPS navigation system are connected with gearbox control by gear change wire harness respectively.
Between gearbox control and GPS navigation system, adopt bus communication control.
Compared with prior art, the beneficial effects of the utility model are:
Gearbox control, on former control logic basis, is realized downshift protection logic by gear selector and velocity transducer;
Between GPS navigation system and gearbox control, adopt bus communication, realize protection and remote control to gearbox.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the schematic diagram of the utility model technology for detection and loop control logic.
Gearbox control in the drawings, 1; 2, gear selector; 3, GPS navigation system; 4, gear change wire harness; 5, gearbox speed change valve; 6, velocity transducer.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
A kind of can downshift the controller of gear-boxes of protection and bus communication, comprise gearbox control 1, gear selector 2, gearbox speed change valve 5, velocity transducer 6 and GPS navigation system 3, gear selector 2, gearbox speed change valve 5, velocity transducer 6 and GPS navigation system 3 are connected with gearbox control 1 by gear change wire harness 4 respectively; Between gearbox control 1 and GPS navigation system 3, adopt bus communication control.
The utility model is in the time of work, Negotiation speed sensor 6 Real-time Obtaining complete machine vehicle speed signal, in the time that gearbox control 1 monitors gear selector 2 downshifts variation, can first judge that the speed of a motor vehicle is whether in the speed of a motor vehicle limit value of target gear, when the speed of a motor vehicle is higher than target gear speed of a motor vehicle limit value, direct export target gear, can continue to export the affiliated gear of the speed of a motor vehicle; When in 5S, detect when the speed of a motor vehicle drops to the low gear speed of a motor vehicle, export corresponding gear; otherwise when 5S, gearbox speed change valve 5 is forced downshift output step by step according to the speed of a motor vehicle, thereby realizes successively decreasing step by step of gearbox gear; gearbox gear seamlessly transits step by step, and gearbox is played a protective role.
Gearbox control 1 and GPS navigation system 3 bus communications, the information of complete machine is uploaded onto the server in real time, realize the monitoring to complete machine, can realize the telecontrol to gearbox control 1 by server simultaneously, make its output control gear, realize remote control.
Claims (2)
