Example Embodiment

[0026] Example 1

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

[0028] Step S101 : read data of each touch screen by means of asynchronous callback respectively, and obtain the whole frame of data by performing packet header analysis on 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 acquiring the entire frame of data, acquire the amount of data stored in the data buffer corresponding to the touch screen corresponding to the entire frame of data, and compare the amount of stored data in the data buffer with a preset buffer threshold. or equal to the buffer threshold, delete the whole frame of data at the head of the corresponding data buffer queue, and store the currently obta...

[0047] Example 2

[0048] According to the 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 system of the present invention includes: an asynchronous callback module 201, a touch screen data analysis module 202, and an entire screen data analysis module 203, wherein:

[0049] The asynchronous callback module 201 is used to read the data of each touch screen by means of asynchronous callback, wherein, in the actual operation process, the data of each touch screen can be respectively read and recalled by setting asynchronous data read callback for the serial port connected to each touch screen. Carry out data reading, so that the data reading of each touch screen is carried out independently of each other, and there is no touch delay caused by the mutual waiting phenomenon caused by the asynchronous packet header;

Example Embodiment

[0066] Example 3

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

[0068] (1) Create a driver program based on HID (Human Interface Device, Human 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 splicing wall, the number of columns of the splicing wall, the resolution of the display unit corresponding to each splicing wall, and the name of the serial port device. After the reading is successful Continue to step (3), if the reading fails, the error code will be returned directly;

[0070] (3) Multiply the number of rows of the video wall created in the driver by t...

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...
