Detailed description of the invention
The overall plan of the present invention is design standard configurations unit on the hardware of infrared touch panel, by driving selection to arrange corresponding configuration information, configuration information can be sent to the particular memory space of infrared touch panel at any time by instruction, in particular memory space unit, storage has the configuration information of various model infrared touch panel, particular memory space is by calling data therein by parameter feedback to main control chip, main control chip assigns them to the respective function in system program after receiving parameter, complete the configuration of infrared touch panel.
Refer to the hardware structure diagram of Fig. 1 and the configuration flow figure of Fig. 2, specifically comprising the following steps that of infrared touch panel standard configurations method of the present invention
Step 1: in order to realize the standard configurations of infrared touch panel, host computer be driven through serial ports send packet to main control chip between, add a specific permanent location；
Step 2: configuration information is sent to this memory element with the form of packet by the driving of infrared touch panel, so that this memory element persistence has the configuration information of the different model touch screen of exploitation, specifically includes following steps:
Step 22: before running infrared touch panel, need to open the driving of infrared touch panel, driving just includes the standard configurations option of infrared touch panel, the content of configuration includes the size setting of touch screen, list multidrop mode selection setting, switch touch screen setting, dirt detection setting, wisp identification setting, click " determination " after setting to exit, wherein:
A) touch screen size: be that the concrete resolution of the touch screen according to company's actual development (such as 768*768,1024*768,1280*1024) selects, differently configured touch screen；
B) single multiple point touching model selection: can select different software algorithms according to different touch modes, under single-touch pattern, in order to ensure to touch precision, smoothness and touch-responsive speed, adopts centroid method to ask for the coordinate of touch point；Under multiple point touching pattern, in order to identify true touch point and pseudo-touch point and determine the movement locus of multiple point touching, it is necessary to adopt a kind of special algorithm to judge true and false touch point, and adopt the movement locus judging method of loci to describe touch point；Ensure the degree of accuracy touched under different mode；
C) switch touch screen is arranged: can realize switching touch screen at any time；
D) specific function is arranged: can select when needed to open wisp identification and dirt detection；Wisp refers to the tiny touch objects that diameter is below 3mm, in existing infrared touch screen light plate, is difficult to the touch objects identifying diameter at below 3mm, if needing to identify that little touch objects will open wisp recognition function；Dirt refers to the dust in natural environment, insecticide and water stain etc., when dirt effective touch scope entering into infrared touch panel etc, effective touch can be disturbed even to produce maloperation, if therefore using touch screen in the environment that dirt is relatively more, it is necessary to select dirt detection to get rid of the interference of dirt；
Step 24: be provided with and after opening driving, standard configurations can be sent to the permanent location on infrared touch panel hardware with the data packet format of 20 bytes by driving, inside memory element, storage has the configuration information of infrared touch panel, configuration information includes the function (such as: single multiple point touching pattern, wisp identification, dirt detection etc.) of the fixing parameter (such as: size, baud rate, serial ports number etc.) of different model infrared touch panel and customer selecting
Step 3: memory element judges the parameter matching corresponding main control chip program after receiving the packet of configuration information, the form again through packet is sent to main control chip；
Step 4: main control chip receives configuration data bag, complete the transmission of configuration information, when after Infrared touch screen systems configuration successful, meeting feedback configuration success instruction is to the driving of host computer, show that configuration is complete, so, infrared touch panel just can use according to configuration is normal, and main control chip controls infrared light board according to this configuration information by infrared light board control circuit.
In described step 2, if producing novel infrared touch panel, the relevant configured parameter of new model can be directly deposited in particular memory location, even again the program in main control chip is write without amendment, host computer drives the configuration information packet that can directly transmit new model to memory element, and memory element is then transferred out parameter and sent main control chip process to；
In described step 4, main control chip is after receiving configuration data bag, the function of bits per inch evidence is judged according to prespecified data packet format, by parameter assignment fixing for infrared touch panel to the global variable of program, functional parameter is then used for arranging correlation function function in opening program, consulting shown in Fig. 3, idiographic flow is as follows:
Step 42: start；
Step 43: main control chip is receiving the configuration data bag that memory element sends；
Step 44: first determining whether that whether the packet received is complete, if imperfect, return step 43, again receive, complete words enter step 45；
Step 45: judge whether the preset parameter of configuration infrared touch panel, if it is, enter next step 46 after configuration preset parameter, otherwise, is directly entered next step 46；
Step 46: judge whether the functional parameter of configuration infrared touch panel, if it is, enter next step 47 after starting power function, otherwise, is directly entered next step 47；
Step 47: judged whether configuration, if it is, enter next step 48, otherwise, returns step 43；
Step 48: send configuration successful order；
Step 49: bring into operation program；
Step 50: terminate.
The foregoing is only the preferred embodiment of the invention, not in order to limit the invention, any amendment made within all spirit in the invention and principle, equivalent replacement and improvement etc., should be included within the protection domain of the invention.
