Described processing unit can be single-chip microcomputer or ARM device.
As shown in Figure 1, described button from top to bottom distributes in the following order: key box 401, is transparent button viewing area directly over it; OLED display module 402, comprises OLED display screen and signal-processing board; Pressing plate 403 in order to fixing OLED display module in key box; Action contact 404, for making reseting leaf produce deformation in pressing operation process, and sets back; Control unit 405: comprise signal processor, memory cell, reseting leaf, JTAG control line, signaling interface; For detecting and having judged whether button 4 pressing operation, progressively perform the flow process in Fig. 2; Seal cover board 406, is covered with one deck moisture seal rubber cushion, guarantees that the display button installed can reach the degree of protection of IP56.When there is pressing operation the button viewing area of key box 401, the OLED display module 402 tightened together, pressing plate 403 and action contact 404 are under the effect of external force, produce displacement, contact makes the reseting shrapnel generation deformation on control circuit board 405, produce voltage signal, the discharge circuit of voltage on control circuit board 405, filter circuit is transferred to signal processor (MCU), signal processor detects and judges change in voltage, perform the step 102 in Fig. 2, when meeting control signal requirement, export control signal to controlled device, call the identification information 6 of the storage of described memory cell simultaneously, be transferred to OLED module 402, upgrade identification information 6, namely step 105 is performed, detect and whether have interface command, as there is no interface command, return to step 102, call memory content to show, if any interface command, perform step 106, fetch interface order, perform step 107 subsequently, whether sense command is the order upgrading memory content, if not, return to step 102, call memory content and show, if so, perform step 108, the renewal memory content information sent according to interface, upgrades memory, then returns to step 102.
If the control object of control panel and controlled system 5 similar, just controlled parameter and state different time, the storage content of display button 4 can be changed by input, make it to mate with controlled system 5.In other words, multiple control panel identical completely, can input different control programs, be stored in display button 4, control different controlled systems, such control panel can be a flexible Application and have the keyboard of Presentation Function, and keyboard fixing with common function is again different.
In figure 3, give the information updating hardware schematic diagram of single display button 4 identification information 6, comprise main frame 1, keyboard 2, display 3(as computer), the renewal of the identification information of display button 4 is completed by MCU development platform software, update of identification information flow process as shown in Figure 2, MCU development platform software is arranged in computer applied algorithm memory, start to perform step 101 after display button 4 powers up, signal processor subsequently in control unit 405 performs step 102, and the identification information calling storage in memory shows in OLED display module 402; In step 103 and 104 is whether the action contact of detection display button 4 and the switching value of reseting leaf formation have key information; Step 105 detects the order whether having the renewal identification information sent to display button 4 interface by main frame 1; Main frame 1 by choosing identification information, identification information 6 or word, picture, character, short and small video file or animation file.Main frame 1 calls identification information at display 3, is confirmed by keyboard 2, is given an order after finally being determined by keyboard 2 by jtag interface to signal processor.The renewal of identification information 6 is completed through step 105, step 106, step 107 and step 108.
For number of times and the marking keys (i.e. the state of a control information of button) of display button of the present invention switching capable of circulation, be stored in the storage unit of the control circuit board 405 shown in Fig. 2, pressing operation occurs once, the processing unit of display button 4 performs 102 and detects that button is pressed down, contact 404 contacts reseting shrapnel and produces level, when level change meets trigger condition, perform 103 and 104, display button displaying contents is synchronously changed, upgrade key state information, export control information, produce corresponding control action.So repeatedly, display button just cyclic switching.When the change that level produces does not meet trigger condition, the push action of display button is invalid.
As needs change, increase or reduce display button function, designed the state of a control information of marking keys 8(and button by main frame 1) application program, power up to display button 4, button display performs 105, judge whether interface command, if any interface command then fetch interface order, perform 106 and 107, jtag interface connects input equipment and the application program of marking keys 8 is cured in the storage unit of the control circuit board 405 shown in Fig. 2, display button 4 upgrades memory content according to order, and the function of display button increases thereupon or reduces.
In sum, the present invention is in daily used field of electrical control, and first itself is a button with stroke, is made up of key box, OLED display, action contact, reseting shrapnel, control circuit board, when pressing keys, as the switch of control unit.The second, in control circuit board, there is the program of solidification, write the function of button and the source code of purposes by demand, and be transferred to the function that OLED display shows current button; 3rd, the function of button and purposes are undertaken changing, increase or reducing by the program changing control circuit board.
Such as, if for handoff functionality on control panel is conventional push button, except button is installed, function that also need be corresponding during slot milling silk-screen button different conditions on panel, when switching state is more (more than 3 kinds), may needs to increase button and realize.OLED display button is while the generation handoff functionality that pushes button, marking keys (i.e. the state of a control information of button) is synchronously along with the button stroke that pressing operation produces each time switches, mark can be word, picture or even animation, if the multiple control units order that need switch fixing and more time, only need a button, repeatedly press continuously, therefore, this invention product has the function of a key multipotency, and keypress function can be changed with the change of purposes demand, the quantity of pushbutton can be greatly reduced, reduce control panel size.
When the control panel (can containing 1, the panel of several or dozens of display button) at display button 4 place is energized, display button 4 works, and its displaying contents according to demand, may change, and also may not change; The content of its display can be word, picture, character, short and small video file or animation file.The processing unit of display button, first from 101 steps power up, calls memory content and shows; Then perform step 102 detect and judged whether that (this button 4 is not keyboard to button 4 pressing operation, it is the button being designed to one with OLED display), as without pressing operation, no matter whether controlled system 5 is energized, program all enters 103, content in display button is constant, the content of display current control state.If any pressing operation, and controlled system 5 is energized, and program performs 104, performs key commands, exports control information, simultaneously the content changing of display button, upgrades state of a control information; If any pressing operation, controlled system 5 is not energized, then perform step 102 and detect and judged whether button 4 pressing operation, until the control panel power-off at display button place.
The parts that the present embodiment does not describe in detail and structure belong to the well-known components of the industry and common structure or conventional means, do not describe one by one here.
