Description
Technical field
The present invention relates to handles to control processing technology field, specially a kind of handle bus module controller.
Background technique
Forklift workability is complicated, and load intensity is big, with the development of modern forklift truck technology technology, while in order to reduce driver's work
Labor intensity, fork truck is also more and more using automatic shift control technology, and automatic speed changing function is stronger and stronger, fork truck installation
Electronic equipment is continuously increased, while needing real-time exchange to improve a large amount of signals such as the safety of fork truck, reliability, and CAN is total
The application of line can be very good to solve the problems, such as exist above, while bussing technique is widely used in fork truck technology.
Handle gearshift, reversing switch power supply are provided by fork truck generator, which is not by processing, signal
Fluctuation is big, while serious by other signal interferences, if handle gearshift, commutation signal are directly entered gearbox control TCU, then
Electrically controlled gearbox shift is driven, the risk that gearbox control TCU has damage is big.
Summary of the invention
It is mentioned above in the background art to solve the purpose of the present invention is to provide a kind of handle bus module controller
Problem.
To achieve the above object, the present invention provides the following technical solutions：A kind of handle bus module controller, including be used for
It is separately connected the switching signal processing module of shift switch, reversing handle switch and change-over switch, the switching signal handles mould
Block is connected with controller, and the controller is connected separately with bus transceiver and power module, and the bus transceiver is connected with
Gearbox control TCU for data exchange and communication.
Processing circuit of the input terminal of the controller respectively with shift switch, reversing handle switch and change-over switch connects
It connects, the shift switch includes three gear B1, B2, B3 shift handle switches, and the reversing handle switch includes the gear commutation of N, F, R tri-
Switch, the change-over switch include manual mode switch and automatic mode switch.
The controller and bus transceiver carry out the reception and transmitting of bus data, and the bus transceiver is to control
Device processed provides differential send and receive.
As shown from the above technical solution, the present invention is by CAN bus technology, using bus transceiver solve handle gearshift,
The interference and damage of the signals to gearbox control TCU such as commutation, while control reliability is improved, accuracy, real-time improves
Working efficiency, reducing harness reduces cost.

Fig. 2 is working principle diagram of the present invention；
Fig. 3 is switching signal circuit diagram of the present invention；
Fig. 4 is bus module logic chart of the present invention.
Specific embodiment
The present invention will be further described by 1-4 with reference to the accompanying drawing：
The bus transceiver is connected separately with shift switch, reversing handle switch and change-over switch, while shift switch packet
Three gear B1, B2, B3 shift handles switch is included, the reversing handle switch includes that N, F, R tri- keeps off reversing switch, the change-over switch
It is switched including manual mode switch and automatic mode, above-mentioned switching signal is by advance switching circuit, retrogressing switching circuit, sky
Position switch circuit, B1 switching circuit, B2 switching circuit, B3 switching circuit and manual/auto mode conversion switch circuit, this implementation
When switching signal processing circuit input end signal in example is positive signal, light emitting diode emits beam, and phototriode receives
Electric current will be generated after light, flowed out from output end, switching signal output signal, wherein resistance R1 plays metering function, capacitor
C1 plays filter action, and when moment is connected in switching signal, surge voltage is big, and increasing capacitor can prevent surge current to signal
Interference；When input end signal is negative signal, diode D2 ends signal, so photoelectrical coupler PS electric current cannot pass through,
Therefore no signal output, the output of switching circuit no signal；The switching signal processing module circuit is by neutral signal N and two poles
Pipe D2 connection, and connect with photoelectrical coupler diode, the photoelectrical coupler diode other end is connected with resistance R1 and is grounded, light
Electric coupler triode one end and capacitor C1 grounding connection, the other end are connect with capacitor C1 and output signal.
TJA1050 CAN bus driver is used in the embodiment, as long as the external anti-jamming circuit appropriate of this driver
Bus circuit can be established, and provides differential transmitting capacity to bus, and controller can also provide differential reception ability, core
Piece TJA1050 carries out level conversion, shunt capacitance C2, C3 between CAN-H and CAN-L foot and ground, for filtering out in bus
Wave is interfered, while also having the effect of transition interference protection, resistance R4 is 120 ohm of bus termination resistance
Shift switch, reversing handle switch and change-over switch signal after the processing of switching signal processing module enters control
Device, controller and bus transceiver Venus data conversion, then bus transceiver is carried out by bus and gearbox control TCU
Bus communication, the gearbox control TCU parse the bus data of reading to judge gear information at this time.
When gear is adjusted to manual mode by the change-over switch, gearbox control TCU only carries out manual shift mode, i.e.,
When switch in B1, gearbox can only be B1 gear, switch in B2, gearbox can only when B2 keep off；When change-over switch is by gear tune
When to automatic mode, gearbox control TCU judges shift signal position, and when switch is at the position B1, gearbox can only be B1
Gear, when switch is at the position B2, gearbox control TCU control solenoid valve carries out self shifter between bl and b 2, works as switch
At the position B3, gearbox control TCU control solenoid valve carries out self shifter between B1, B2 and B3
Switching signal in the present embodiment enters controller, controller after the processing of switching signal processing module
Embodiment described above only describe the preferred embodiments of the invention, not to the scope of the present invention into
Row limits, and without departing from the spirit of the design of the present invention, those of ordinary skill in the art make technical solution of the present invention
Various changes and improvements out should all be fallen into the protection scope that claims of the present invention determines.
