Detailed description of the invention
For the benefit of the understanding to structure of the present utility model, illustrates below in conjunction with drawings and Examples.
Fig. 1 is the structural representation of the automobile-used automotive air-conditioning controller based on LIN bus of this utility model.
Shown in Fig. 1, this utility model provides a kind of automotive air-conditioning controller based on LIN bus, including airconditioning control shell, it is located at the circuit board group 50 in described airconditioning control shell, described circuit board group 50 includes first circuit board, second circuit board, being divided into the panel module 10 on first circuit board and the control module 20 being located on second circuit board, described panel module 10 is connected with controlling module 20 communication, and the LIN bus transceiver 40 being connected with described control module.
Described panel module 10 include panel ECU11 and respectively with the described panel ECU11 key entry unit 12 being connected and display unit 13.
Further, described control module 20 includes the drive circuit unit 22 controlling ECU21 and being connected with described control ECU21, and described control ECU21 is connected with corresponding sensing equipment 30.In the present embodiment, described drive circuit unit 22 includes controlling ECU21 compressor drive circuit 221, motor-drive circuit group 222 and the actuator driven circuit 223 being connected with described respectively.Further, described sensing equipment 30 includes controlling ECU indoor and outdoor temperature sensor, evaporator sensor and the sunlight sensor being connected with described respectively, and described motor-drive circuit group 212 includes controlling ECU21 pattern damper motor drive circuit, blender door motor-drive circuit, blower motor drive circuit and the cycle throttle motor-drive circuit being connected with described respectively.
In the present embodiment, this automotive air-conditioning controller also includes the backlight regulon and power supply, the clock-reset circuit that regulate display unit brightness.In practical application, this automotive air-conditioning controller also can arrange and control the ECU power amplifier able to programme being connected.
Hereinafter the concrete application specific details of the Vehicular multifunctional door window control system pair that this utility model provides is described in detail.
First pass through analysis LIN agreement, the useful information such as work state information and various linear transducers such as obtaining mode air door, mixed air door, inside/outside cycle throttle, air force, compressor, rear defrosting bus, forms own control protocol after information analysis is arranged.
Air-conditioner controller realizes the communication with LIN bus, have employed the method judging interruption times, once bus occurs effective dominant level, controller proceeds to high-priority interrupt immediately and processes function, it is first determined whether the field, interval sent for host node, if field, interval then receives synchronizing field and identifier field, if not synchronizing field then exits wait and interrupts next time.After receiving correct identifier, if identifier requires that system sends information, system then sends data fields and verification field, starts waiting for again receiving next frame data after having sent.If identifier is not required the machine carries out data transmission, then receive data fields subsequently and verification field, in mastery routine, judge that whether received data is effective to the machine further according to identifier, effectively just handle accordingly, invalid, do not process, repeatedly start again after having processed to continue executing with.
The function of LIN bus air conditioning system includes vehicle interior temperature and humidity is automatically adjusted, return air and air supply pattern automatically controls and the function such as drive manner and ventilation volume control.The setting that ECU will be undertaken by the button on air-conditioning display control panel according to driver or passenger, air conditioning system is made automatically to run, and according to the signal that various sensors input, wind pushing temperature and air supply velocity are adjusted in time, make the driving environment in car remain optimum state.
When the vehicle interior temperature of the outer temperature of car with setting is closer to, ECU can shorten the working time of refrigeration compressor, even at, when not starting compressor, vehicle interior temperature just being made to keep setting state, reach energy-conservation purpose.By being placed in the air-conditioning display control panel on automobile instrument panel, by LCD can show at any time at that time temperature, vehicle interior temperature, the outer temperature of car, air supply velocity, return air and the information such as air outlet state and the air conditioning system method of operation are set, enable a driver to understand all sidedly in time the duty of air conditioning system.LIN bus is according to the detection of sensor acquisition signal automatic fault and safety energy: the state of system can be detected by LIN bus by self-diagnosable system, and failure condition is judged, when system breaks down, make the incoming corresponding fail safe situation of system, it is prevented that fault expands further.
The automotive air-conditioning controller based on LIN bus that this utility model provides, adopt Distributed Design, the key-press input of circuit board and display function are realized on air-conditioning panel, and the control function of execution unit is controlling realization on ECU, just can realize general design, different vehicles has only to change the circuit board of key-press input and display function, and the ECU realizing Actuator Of The Air Conditioner part control function controls module and just can realize general.Thus reducing difficulty and the risk of exploitation, and after realizing large-scale production, the concordance of product can be improved and reduce the cost of product, and LIN bus carries out data sharing transmission, the integration and the stability that make system are greatly improved, and the ratio of performance to price of terminal, on-the-spot operability and maintainability etc. all will have very big raising.Reduce sensing vehicle, detection number of devices, reduce automotive wire bundle, alleviate complete vehicle weight, reduce the fault rate of automobile, reduce the production cost of automobile, cost of serving, and then save the energy, be greatly improved driver's amenity and air-conditioning maintainability.
