Embodiment 1

[0027] see figure 1 As shown, it is a flowchart of an embodiment of the multi-screen splicing touch control method of the present invention, as figure 1 As shown, the multi-screen splicing touch control method in this embodiment includes the following steps:

[0028] Step S101: Read the data of each touch screen by means of asynchronous callback, respectively, and obtain the whole frame data by analyzing the packet header of the data of each touch screen in the process of reading the data of each touch screen, and enter step S102;

[0029] Step S102: After obtaining the entire frame of data, obtain the amount of stored data in the data buffer corresponding to the touch screen corresponding to the entire frame of data, compare the amount of stored data in the data buffer with the preset buffer threshold, and if it is greater than or equal to the buffer threshold, delete the entire frame data at the head of the corresponding data buffer queue, and store the currently acquired e...

Embodiment 2

[0048] According to the above-mentioned multi-screen splicing touch control method of the present invention, the present invention also provides a multi-screen splicing touch control system, see figure 2 As shown, the multi-screen splicing touch control system of the present invention includes: an asynchronous callback module 201, a touch screen data analysis module 202, and a whole screen data analysis module 203, wherein:

[0049] The asynchronous callback module 201 is used to read the data of each touch screen through the mode of asynchronous callback respectively, wherein, in the actual operation process, can read the data of each touch screen respectively by respectively setting asynchronous data reading callback to the serial port connected to each touch screen Data reading is carried out, so that the data reading of each touch screen is carried out independently of each other, and there is no delay in touching due to the mutual waiting phenomenon caused by the out-of-s...

Embodiment 3

[0067] In order to further understand the solution of the present invention, a specific example is taken as an example below to illustrate the present invention, but the present invention is not limited to the solution in this embodiment. The multi-screen touch method in this embodiment includes the following steps:

[0068] (1) Create a driver based on HID (Human Interface Device, human-machine interface device) device on the underlying driver layer architecture;

[0069] (2) When the driver is initialized, first read the parameters of the registry, read the number of rows of the video wall, the number of columns of the video wall, the resolution of the display unit corresponding to each video wall, and the name of the serial port device. After reading successfully Continue to step (3), if the reading fails, the error code will be returned directly;

[0070] (3) Multiply the number of rows of the splicing wall in the driver by the number of columns of the splicing wall, the ...

Abstract

The invention provides a multi-screen splicing touch control method and a system. The method comprises the following steps of: respectively reading the data of each touch screen in an asynchronous callback manner and obtaining whole-frame data through respectively carrying out packet head analysis on the data of each touch screen in the process of reading the data of each touch screen; after the whole-frame data is obtained, obtaining data volume stored in a data buffer area corresponding to the touch screen corresponding to the whole-frame data, comparing the data volume stored in the data buffer area with a preset buffer area threshold value, deleting the whole-frame data of a corresponding data buffer area queue head if the data volume is larger than or equal to the buffer area threshold value and storing the currently-obtained whole-frame data into a data buffer area queue tail; directly storing the currently-obtained whole-frame data into the data buffer area queue tail if the data volume is less than the buffer area threshold value; and respectively reading and processing the one-frame data of the data buffer area queue head on each touch screen every a preset time. The invention can solve the problems of touch time delay caused by data asynchronization and touch interrupt caused by discontinuity.

Description

technical field [0001] The present invention relates to the field of touch technology, in particular to a multi-screen splicing touch control method and system. Background technique [0002] With the rapid development of information technology, touch technology has been widely used in all walks of life. It provides a new way of human-computer interaction, which brings great convenience to the user's operation and triggers a new era of human-computer interaction. change. [0003] At present, in mainstream touch products, such as mobile phones, PADs, PCs, etc., generally only touch applications based on a single touch screen, and due to the characteristics of the touch technology used, there are certain restrictions on the size of the touch screen, which cannot be achieved. Large-sized touch applications, however, with the diversification of market applications, based on the application requirements of various industries, small-sized touch screens can no longer meet the growi...
