Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail with reference to the accompanying drawings, and it is apparent that the described embodiments are only a part of the embodiments of the present invention, not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Fig. 1 illustrates a system architecture to which an embodiment of the present invention is applicable, which may include a front panel 100 and a coupler 200.
Wherein, the front panel 100 and the coupler 200 can communicate through a serial communication protocol.
The front panel 100 can be provided with a plurality of keys, the front panel 100 is further provided with a touchable display area, a user can set the number of the keys and other parameter information in the display area, and the front panel is further provided with a plurality of contacts.
The coupler 200 may be an MCU for transmitting corresponding setting parameter information to the front panel 100 and controlling the controlled device according to a pre-stored control command.
The front panel and the coupler have independent hardware and software designs. The coupler module is responsible for analyzing the content of the database and has a communication function with the bus, and the front panel is responsible for key detection and other functions. The front panel and the coupler are communicated through a serial port, and a corresponding communication protocol is customized according to requirements. In a communication protocol, a communication baud rate is specified to be 19200, 8-bit data bits, no parity check and CRC-8 check. The communication data format is as follows: the format of the data sent down by the coupler is shown in table 1. The format of the data reported by the front panel is shown in table 2.
TABLE 1
| Frame header | Frame length | Command code A | Command code B | Command data | CRC-8 |
| A5 5A | 1Byte | 1Byte | 1Byte | N Byte | 1Byte |
TABLE 2
| Frame header | Frame length | Command code A | Command code B | Command data | CRC-8 |
| A5 5A | 1Byte | 1Byte | 1Byte | N Byte | 1Byte |
The command code a is detailed as follows:
the command code a is mainly used to interpret the function of a frame of data, and the direction of the data (to indicate whether the data originates from the front panel or from the coupler).
The command code B is used in conjunction with the command code a to perform detailed parsing of a frame of data.
Communication flow: after the device is powered on for the first time and the front panel is initialized, a command is sent to the coupler, wherein the command code A is 0x03, and the command code B is 0x13, which indicates that the initialization is completed. After receiving the command, the coupler firstly sends response data and then sends a setting instruction.
It should be noted that the structure shown in fig. 1 is only an example, and the embodiment of the present invention is not limited thereto.
Based on the above description, fig. 2 shows in detail a flow of a method for detecting a touch point by an intelligent key panel according to an embodiment of the present invention, where the flow may be executed by an apparatus for detecting a touch point by an intelligent key panel.
As shown in fig. 2, the process specifically includes:
in step 201, level change information of the configured contacts is obtained.
In the embodiment of the present invention, before obtaining the level change information of the configured contact, the configured contact needs to be determined first, where the configured contact is determined according to the key number information of the front panel, and specifically, the configured key number sent by the front panel may be obtained first, and the configured key number is configured by the user. And then determining the configured contact corresponding to the key of the front panel and the controlled device corresponding to the key of the front panel according to the configured number of the keys and the corresponding relationship between the preset number of the keys and the contact and the controlled device. The level change information of the contacts of the configuration is generated after the user presses a key on the front panel.
The number of the keys configured on the front panel is less than or equal to the number of the contacts of the front panel, where the contacts of the front panel are contacts of a fixed number, and the contacts of the front panel are contacts preset when the front panel leaves a factory. The contact points arranged corresponding to the number of arranged keys are contact points corresponding to the arranged keys selected from a fixed number of contact points.
For example, taking the controlled device as an LED as an example, the structure of the contact of the front panel of the key switch can be as shown in fig. 3. The LED1 corresponds to the contact S1, the LED2 corresponds to the contact S2, the LED3 corresponds to the contact S3, the LED4 corresponds to the contact S4, the LED5 corresponds to the contact S5, the LED6 corresponds to the contact S6, the LED7 corresponds to the contact S7, and the LED8 corresponds to the contact S8.
The preset number of keys based on the contacts shown in fig. 3, the corresponding relationship between the contacts and the controlled device may be as shown in table 3.
TABLE 3
Based on table 1, the correspondence between the number of keys and the number of contacts can be found as follows:
number of keys: 2 bits; corresponding to contacts S4, S5.
Number of keys: 3 bits; corresponding to contacts S4, S3, S8.
Number of keys: 4 bits; corresponding contacts S1, S3, S6, S8.
Number of keys: 5 bits; corresponding contacts S1, S3, S6, S7, S8.
Number of keys: bit 6, corresponding to contacts S1, S2, S3, S6, S7, S8.
Further, based on the configuration shown in fig. 3, a controlled device corresponding to each contact can be obtained.
Before the detection of the level change of the contact point, a panel database can be configured through a PC configuration tool ETS, in the database design of the key panel, the parameters of the key response time are reserved, and the database is downloaded to the corresponding coupler by using the ETS. When the product is electrified to work, the singlechip program in the coupler transmits the parameters to the front panel, and the main chip of the front panel enters a normal working state and executes the program according to the parameters. The front panel automatically judges the contact points to be detected according to the parameter setting sent by the coupler. Each contact is respectively connected with different I/O ports on the singlechip of the front panel, and the program of the front panel detects the approximate realization of the corresponding I/O port:
the I/O of the singlechip is connected with the contact, and once the contact is pressed down, the level of the I/O of the singlechip changes. For example, when the contact is not pressed, the level of the I/O is high. When the contact is pressed, the level changes to low level; when the contact is released, the voltage level changes to high again. The singlechip regularly scans the change of the I/O level, once the level changes, the contact is pressed or loosened, and then different operations are respectively executed according to preset settings. For example, when a user presses a key, the single chip of the front panel automatically detects the contact.
Wherein the change information of the level can be as shown in fig. 4.
After the level change information is obtained, the states of short press, long press, release and the like of the key can be judged according to the level change of each contact.
And step 203, controlling the controlled equipment corresponding to the keys of the front panel according to the states of the keys of the front panel.
And controlling corresponding controlled equipment according to different control instructions corresponding to different key states. For example, if the state of the contact S1 is short pressed and the corresponding control command is on, the LED1 may be controlled to be on. If the state of the contact point S1 is long pressed and the corresponding control command is flashing, the LED1 may be controlled to flash.
By using the method for detecting the contact provided by the embodiment of the invention, the hardware of the front panel can be replaced by panels with two keys, three keys, four keys, five keys, six keys, seven keys and eight keys at will. The more complex the software function is, the more communication objects need to be defined, the coupler is developed based on a protocol stack, and the number of the communication objects is limited, so that the product is designed to have 8 fixed contacts according to the current function requirement. The number of functions and the number of keys both relate to the serial communication protocol of the front panel and the coupler, so if the number of keys exceeds 8, the communication protocol of the coupler and the front panel needs to be changed.
The above embodiment shows that level change information of the configured contacts is obtained, the configured contacts are determined according to the number information of the keys configured on the front panel, the number of the contacts on the front panel is multiple, the state of the keys of the front panel is determined according to the level change information of the configured contacts, and the controlled device corresponding to the keys of the front panel is controlled according to the state of the keys of the front panel. The controlled equipment is controlled by automatically detecting the level change information of the configured contacts through the contacts configured according to the number of the keys on the front panel, and the problem that the keys on the front panel cannot be replaced randomly due to the fact that the number of the keys on the front panel corresponds to the number of the contacts one to one at present can be solved. The front panel of various different numbers of keys can be freely replaced, the replacement cost of a user is reduced, and the user experience is improved.
