Abstract
The utility model provides an integrated bus rocker switch controller, which solves the problems that conventional rocker switches are high in cost, complex to assemble and high in fault rate. The rocker switch controller is composed of an MCU controller, a power supply processing circuit, a backlight detection circuit, a rocker switch test circuit, a backlight and indicator light control circuit, an EE memory chip, a DEBUG interface, a CAN interface, and a LIN interface. Compared to conventional separated pure mechanical rocker switches, the rocker switch controller can electronize, informatize and intelligentize passenger car body load control. Operation information of a driver can be conveyed via communication measures, and thus functions of a passenger car can be extended without increasing additional wires. For example, a tachograph can easily record various operational processes of a car during operation through connecting a CAN bus or a LIN bus to the rocker switch controller.
Description
Technical field
The utility model relates to a kind of rocker switch, relates in particular to the bus rocker switch controller of integrated form.
Background technology
On passenger vehicle, have very multichannel loading to need driver in operational process, to carry out switch control, most employing is at present installed the rocker switch of Purely mechanical one by one and is realized on instrument desk.The load of every road all needs an independent switch, on general car, has more than 30 switch, and each switch needs to connect control wire harness, add the line backlight of each switch, cause below instrument desk wire harness intensive, not only increase wire harness cost, also increased the complicacy of wire harness assembling.On the other hand, switch need to pass through larger electric current, splits the overcurrent capability of closing inner structure and switch connector, requires all very highly, also causes the cost of traditional rocker switch high, and failure rate is difficult to reduction.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of bus rocker switch controller of integrated form is provided, and solves the problem that cost is high, assembling is complicated, failure rate is high that traditional rocker switch exists.
The utility model solves the problems of the technologies described above by the following technical solutions:
Bus rocker switch controller is comprised of MCU controller, power supply processing circuit, testing circuit backlight, rocker switch testing circuit, backlight and indicating lamp control circuit, EE storage chip, DEBUG interface, CAN interface and LIN interface.
Described power supply processing circuit, backlight and indicating lamp control circuit, testing circuit backlight and rocker switch testing circuit are connected respectively to MCU controller; Described MCU controller inside is provided with EE storage chip, is provided with DEBUG interface, CAN interface and LIN interface on described MCU controller.
The utility model adopts technique scheme to have following beneficial effect:
1, compare the pure mechanical rocker switch of traditional separate type, the utility model can be realized the electronization that bus body load is controlled, informationization, intellectuality.
The high-power electric current of 2 ,Ge road loads is not passing through rocker switch again, greatly reduces the failure rate of rocker switch.
3, each rocker switch at least will have 4 lines in the past, comprises electric power incoming line, power outlet, backlight control line and ground wire, and 8 rocker switchs are exactly 32 lines, if there is the rocker switch of sophisticated functions, wire harness quantity can be more.Use after bus rocker switch controller, wire harness quantity reduces greatly, is very beneficial for car load and installs, and the space availability ratio of instrument desk inside is also had to very large lifting.
The information of 4, carrying out driver's operation by means of communication is transmitted, do not increasing under the prerequisite of extra wire harness, facilitate passenger vehicle Function Extension, such as drive recorder only need to connect upper bus rocker switch controller, the just various operating process of registration of vehicle in operational process very easily by CAN bus or LIN bus.
Accompanying drawing explanation
Fig. 1 is structured flowchart of the present utility model.
Fig. 2 is work schematic block diagram of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
Bus rocker switch controller is as described in Figure 1 comprised of MCU controller 1, power supply processing circuit 2, testing circuit backlight 3, rocker switch testing circuit 4, EE storage chip 5, backlight and indicating lamp control circuit 6, DEBUG interface 7, CAN interface 8 and LIN interface 9.
Described power supply processing circuit 2, backlight and indicating lamp control circuit 6, testing circuit backlight 3 and rocker switch testing circuit 4 are connected respectively to MCU controller 1; Described MCU controller 1 inside is provided with EE storage chip 5, is provided with DEBUG interface 7, CAN interface 8 and LIN interface 9 on described MCU controller 1.
The work schematic diagram of bus rocker switch controller is as shown in Figure 2 connected with combination instrument 11, BCM control module 12, diagnostic equipment 13 and Tachographs 14 in CAN bus 10, and the CAN interface 8 of bus rocker switch controller is connected to CAN bus 10.
Workflow of the present utility model is as follows:
1, driver's switch motion detects: after bus rocker switch controller powers on, automatically start to detect the duty of each embedded rocker switch.
2, switch pilot lamp is controlled: bus rocker switch controller, after confirming that certain switch is pressed, is lighted relay indicating light automatically, facilitates driver to determine the duty of respective load, and relay indicating light color is made according to customer requirement.
3, backlight lamp control: bus rocker switch controller, after backlight open being detected, is lighted the backlight of each rocker switch, facilitates driver to identify the icon of each button.
4, bus data sending and receiving: the communications protocol of bus rocker switch controller by client's appointment sends to bus by the state of a control of each rocker switch in real time and get on.
5, push button longevity statistics: bus rocker switch controller is automatically added up the work times of each button when work, and by bus, these data is sent, and facilitates tracing trouble reason.
