Description

车载CAN总线按键面板及其控制方法 Vehicle CAN bus and a control method of the key sheet

技术领域 FIELD

[0001] 本发明涉及一种按键面板及其控制方法,尤其涉及一种车载CAN总线按键面板及其控制方法。 [0001] The present invention relates to a key sheet and a control method, and particularly to a CAN bus and a control method of the vehicle-mounted keypad.

背景技术 Background technique

[0002]目前国内外工程机械车辆上普遍使用的是翘板开关加一个控制器来实现设备的灯光、空调、行走、臂架控制等功能控制。 [0002] The current widespread use of the domestic construction machinery plus vehicle is a rocker switch controller to achieve lighting equipment, air conditioning, traveling, boom control function control. 这种控制方式带来几个问题: A few problems this type of control:

[0003] I)成本非常高。 [0003] I) the cost is very high. 由于使用了2种部件,尤其是控制器价格不菲。 The use of two kinds of components, in particular the controller expensive.

[0004] 2)使用的翘板开关是机械式开关,是易损件,一般寿命不到10万次。 [0004] 2) using the rocker switch is a mechanical switch, is consumable, the general life of less than 100,000.

[0005] 3)翘板开关加控制器所占用的物理空间非常大,而工程车辆上部件很多,原本位置就不够,导致驾驶舱位置非常局促。 [0005] 3) plus rocker switch physical space occupied by the controller is very large, and many engineering vehicle member, the home position is not enough, resulting in very cramped position cockpit.

[0006] 4)布线复杂。 [0006] 4) routing complexity. 翘板开关每一个都需要3根线,20个翘板开关需要接60根线,而且与现有的控制器距离间隔较远,布线成本高且维护麻烦。 Rocker each requiring three wires, rocker switches 20 need to take the line 60, and the controller from the conventional widely spaced, high wiring cost and maintenance problems.

[0007] 如果采用按键开关和指示灯,则又存在如下问题: [0007] If a key switch and indicator light, and there is a problem:

[0008] I)每个按键上的指示灯需要单独显示,背景灯需要一直亮,彼此之间不能相互干扰。 Each key indicator on the [0008] I) to be displayed separately, need to have a bright background light, they can not interfere with each other. 在设计时由于一共要在小尺寸里面集成几十个个LED指示灯,而材料是硅胶。 Since the total designed to integrate tens of small size LED is all inside, while the material is silicone. 硅胶的特性是能够透光。 Characteristics of silica gel is capable of transmitting light. 这将会导致一个指示灯点亮的时候,旁边的指示灯区域也会获得灯光。 This will lead to a lamp lit when the area next to the indicator lights will be obtained. 这种情况在指示灯多的时候特别容易出现。 This is particularly likely to occur in the indicator more time. 这个关键技术不解决,就无法有效识别哪个指示灯是点亮状态,从而无法使用。 The key technology is not resolved, it can not effectively identify which indicator is lit state, and thus can not be used.

[0009] 2)按键寿命控制 [0009] 2) Control key life

[0010] 由于车载按键面板集成了几十个按键在一块面板上,使用的是硅橡胶,在设计时很难控制硅胶的平整度,即使平整了,当手指按下时,被按住的硅胶按键会塌下,而边上的按键会鼓起,一会影响手感,更重要的会影响寿命。 [0010] Since the vehicle key sheet integrates a few keys on the panel, a silicone rubber is used in the design is difficult to control the flatness of the silica, even if the formation, when the finger is pressed, is pressed silica gel button will collapse, and the edge of the button will muster, one will affect the feel, more importantly, it will affect the life. 长此以往,按键很容易按塌陷。 Over time, the keys are easy to press collapse. 这个关键技术将会影响按键的使用寿命。 This key technology will affect the life of the keys.

[0011] 3)电流及热量控制 [0011] 3) current and thermal control

[0012] 车载按键面板需要使用了上百个Led,而且要求在强光下能够显示。 [0012] The vehicle-mounted keypad requires hundreds Led, but also requires the ability to display in bright light. 这就要求在选择LED时必须选择IOOnit左右的LED,而长寿命的LED通过的电流都要超过30mA,80个LED同时打开时电流则需要2.5A,加上设计时需要冗余50%,则最好需要5A的输出电流。 This will require about IOOnit selected LED in the choice of LED, the current through the LED long life should be more than 30mA, while when the LED 80 is required opening current 2.5A, plus 50% redundancy design requires, then preferably required output current of 5A. 而常用的电源模块都只能提供3A的电流。 And commonly used power modules can only provide a current of 3A. 怎样提供5A的电流这将是设计的关键所在。 How to provide current 5A This will be the key to the design. 同时所有的LED都打开时,热量非常大,如何控制热量也是一大难点。 At the same time all the LED are turned on, heat is very large, how to control the amount of heat is a major difficulty.

[0038] 请继续参见图2和图3,本发明提供的车载CAN总线按键面板,其中,所述透明硅胶按键区4按行列呈矩阵分布,所述LED指示灯7和黑色硅胶隔离区5分布在透明硅胶按键区4的上方,所述LED背景灯8分布在透明硅胶按键区4的两侧,如图4所示。 [0038] Please continue to refer to FIG. 2 and FIG. 3, the present invention provides a vehicle CAN bus button panel, wherein the transparent silicone keypad 4 rows and columns in a matrix distribution, the LED 7 and the distribution of black silicone isolation region 5 in the above transparent silicone keypad 4, the LED backlight 8 located on both sides of the transparent silicone keypad 4, as shown in FIG.

[0039] 本发明采用的透光材质是硅胶,硅胶本体是透明色的,可以充分利用这点解决背景灯透光问题,以使得按键上的图标能够在夜晚显示。 [0039] The transparent material used in the present invention is silica gel, a silica gel body is transparent color, can take advantage of this to solve the problem background light transmissive, so that the key can be displayed on an icon at night. 为了避免背景灯和按键上方的指示灯相互干扰,也为了避免按键上方指示灯之间的干扰,对硅胶采用了特殊的双色注塑工艺。 To avoid backlight lights interfere with each other and above the key, and to avoid interference between the keys above the indicator on silica gel using a special color injection molding process. 所述黑色硅胶隔离区5通过在透明硅胶中进行二次注塑形成。 The black silicone isolation region 5 is formed by overmolding a transparent silica gel. 由于二次注塑颜色为黑色,其他区域为透明色,这样背景灯部分与指示灯之间被黑色塑胶遮挡,不会串扰光源进入。 Since the overmolding color is black, other areas as transparent, so that light is blocked by a black background between the plastic portion and the indicator, crosstalk does not enter the light source. 同时指示灯之间由于都是黑色的,光源也不会相互干扰,从而彻底解决光源干扰问题。 At the same time between the indicator they are black due to the light source will not interfere with each other, thus completely solve the light interference problem.

[0040] 本发明提供的车载CAN总线按键面板,所述按键主体6选用锅仔片按键,所述锅仔片按键和PCB板2之间设有通孔9,如图4和图5所示。 [0040] The present invention provides a vehicle CAN bus key sheet, the key dome sheet selection key body 6, the through-hole 9 is provided between the dome 2 and the key PCB, 4 and 5 . 本发明使用锅仔片作为按键主体6,锅仔片的使用寿命非常高,可以达到100万次以上。 The present invention is used as a key dome body 6, the service life of the metal dome is very high, it can reach more than one million times. 如果使用其他类型的按键如轻触开关的话,使用寿命短,且产品厚度较厚。 If other types of keys such as a tact switch, then, short life, and the product thicker. 整体平整性没有保证。 Overall flatness is not guaranteed. 再配合使用硅胶作为按压对象。 Together with silica gel as the pressing object. 这样可以充分应用硅胶的固有弹力来确保锅仔片能有效回弹且受力非常均匀,保证了使用寿命。 This application-specific sufficiently elastic silicone dome to ensure effective and resilient force is very uniform, ensure the service life. 此外,在每个锅仔片与PCB板之间留出缝隙,即设置小圆点通孔9,从而保证每次锅仔片被压下去时气流能够释放,大大延长锅仔片的使用寿命。 Further, each of the dome between the PCB leaving a slit, i.e. dots provided through holes 9, so as to ensure the gas flow can be released each time the dome is pressed down, greatly extending the life of the dome.

[0041] 本发明提供的车载CAN总线按键面板,所述每个透明硅胶按键区4的上方优选设有三个LED指示灯7,所述CPU模块通过GPIO 口连接LED指示灯7,要实现对每个指示灯都单独控制,需要每个指示灯占用CPU的I个GPIO 口,这样指示灯越多则需要的CPU资源越多,以20个按键为例,每个按键配置3个指示灯,则需要CPU提供至少80个GPIO 口,每个指示灯需要30mA电流,再加上背景灯至少需要20个,则最少需要2.4A电流,冗余设计则需要提供5A电流。 [0041] The present invention provides a vehicle CAN bus key sheet, each of said transparent silicone keypad 4 is preferably provided above the three LED 7, the LED 7 connected to the CPU module through the GPIO port to achieve for each LEDs are individually controlled, each lamp needs to CPU-I a GPIO port, the more the need for the more CPU resources such lights to Example 20 keys, each key arranged three LEDs, the CPU needs to provide at least 80 GPIO ports, each lamp needs to 30mA, plus at least the backlight 20, then the minimum of 2.4A current, it is necessary to provide redundant design 5A. 这对PCB设计和CPU选择来说非常困难,而且不利于扩展。 It is very difficult for PCB design and selection for CPU, and not conducive to expansion. 本发明通过CPU的一个GPIO 口来轮询控制8个指示灯。 The present invention is polling control indicator 8 via a GPIO port of the CPU. 如果控制80个指示灯只需10个GPIO 口即可,这样节省了CPU资源,同时控制的8个指示灯只需I个指示灯的电流30mA。 If the control lights 80 can only GPIO port 10, which saves CPU resources, while controlling the lamp 8 lights only the I current 30mA. 这样总体只需要 So overall only

0.3A电流,大大降低了输出电流,从而也控制了热量。 0.3A current, greatly reduces the output current, thus controlling the heat.

[0042] 本发明将所有的按键和指示灯集成到PCB板2上,通过CPU采集到按键和指示灯的信息,然后经过程序运算后通过CAN总线发送出去,从而实现了CAN总线控制。 [0042] The present invention will be all the buttons and indicator lamps integrated into the PCB 2, the information collected by the CPU and key indicators, after the program operation and then sent via the CAN bus, in order to achieve a CAN bus. 这样的集成方式便于进行程序控制,通过CAN总线控制大大减少了布线,只需4根线即可实现按键与指示灯的控制,而且距离可以100多米,节省布线空间。 Such an integrated manner to facilitate program control, via the CAN bus control greatly reduce the wiring line can be realized only four control buttons and LEDs, and the distance can be more than 100 m, the space-saving wiring.

[0043] 在工地上运行的车辆噪声非常大,基本听不清楚。 [0043] The vehicle for operation on the site very noisy, basic hear. 本发明的车载CAN总线按键面板提供了声音和指示灯共同指示按键状态,确保每次按键按下的状态是确认的。 Vehicle CAN bus key sheet of the present invention provide a lamp and sound common key status indication, to ensure that each key pressed state is confirmed. 每个透明硅胶按键区4上方的LED指示灯7和位于该透明硅胶按键区4下方的按键主体6并联在一起并连接喇叭进行同步控制。 4 above each LED is a transparent silicone keypad button body 7 located below the transparent silicone keypad 4 and 6 are connected together in parallel and synchronous control horn. 通过在PCB板2中加入喇叭和LED灯,通过CPU进行同步控制,当按键按下时,相应的LED灯亮起,同时驱动喇叭响起,这样就实现了声光一体控制;而传统的按键无法做到。 , By addition of a horn and an LED lamp in the PCB 2 by the CPU synchronization control, when the key is pressed, the corresponding LED lights, driving the speaker sounded simultaneously, thus achieving a sound and light integral control; traditional keys do not to.
