Based on the above hardware structure, the method embodiment of the present invention is presented.
Referring to fig. 2, fig. 2 is a flowchart of a first embodiment of a cascade device parameter adaptive acquisition method according to the present invention, and in combination with fig. 2, the method includes:
Step S10, the instruction identifying module receives a control instruction, and obtains control parameters according to the control instruction and sends the control parameters to the adaptive module, where the control parameters include: adaptive function parameters and request instructions.
As an implementation manner, in this embodiment, with reference to fig. 3, fig. 3 is a schematic diagram of an adaptive acquisition device for parameters of a cascade device according to the present invention, and the instruction identifying module acquires a control instruction data_in, and acquires, according to the control instruction, a control parameter, where the control parameter includes an adaptive function parameter and a request instruction, and the request instruction includes an addressing instruction and an adaptive parameter instruction.
Specifically, as an implementation manner, in this embodiment, in the cascaded LED device, the position of the dead LED may be determined through the display effect, the LED device is newly installed at the position of the dead LED, and the control instruction is written when the newly installed LED device leaves the factory. When the LED device is powered on, the instruction identification module receives a control instruction written in advance in the newly-installed LED device, and obtains control parameters from the control instruction according to the control instruction, wherein the control parameters comprise self-adaptive function parameters and request instructions, and the request instructions comprise addressing instructions and self-adaptive parameter instructions.
Step S20, the self-adaptive module judges whether to start the self-adaptive first function according to the control parameter; and if the adaptive first function is started, alternately sending the request instruction to a front stage or a rear stage starting the adaptive first function, and waiting for the front stage or the rear stage to return data.
In this embodiment, the adaptive module determines to turn on the adaptive first function or the adaptive second function according to the adaptive function parameter in step S10. When the adaptive function parameter is 1, starting an adaptive first function; and when the adaptive function parameter is 0, starting the adaptive second function.
The request instruction comprises an addressing instruction and an adaptive parameter instruction, the addressing instruction can adapt to address parameters, and the adaptive parameter instruction can adapt to various parameters. If the transmitted request instruction is an addressing instruction, the device can acquire the address information of the current position from the returned data of the front-stage device or the rear-stage device; if the transmitted request instruction is an adaptive parameter instruction, the device can acquire various parameters including address information, such as current gain, lamp channel number, and the like, from the returned data of the front-stage device or the rear-stage device.
Specifically, as an implementation manner, in this embodiment, the parameter loading module writes the control parameter obtained by the instruction identifying module into the programmable storage medium, after the device is powered on, the parameter loading module reads the control parameter in the programmable storage medium, and transmits the control parameter to the adaptive module, and the adaptive module determines to start the adaptive first function or the adaptive second function.
Further, the adaptive module judges whether to start the adaptive first function or the adaptive second function according to the adaptive function parameters transmitted by the parameter loading module. When the adaptive function parameter is 1, starting an adaptive first function; and when the adaptive function parameter is 0, starting the adaptive second function.
Further, when the device starts the self-adaptive first function, a request instruction sending module in the self-adaptive module sends a request instruction to the advanced device, wherein the request instruction comprises an addressing instruction and a self-adaptive parameter instruction, and the addressing instruction can adapt to an address parameter, so that address information of the newly-installed LED is obtained. When the request instruction sending module in the self-adaptive module sends a request instruction to the advanced equipment, and meanwhile, the alternating communication control module selects a channel of the address line adri as a sending function, the two-way port control module switches the state of the address line adri into an output state, and the two-way port control module is matched with the request instruction sending module to send the request instruction to the advanced equipment to complete the sending action of the request instruction, and after the request instruction is sent, the self-adaptive module enters a waiting state to wait for the return data of the advanced stage in a waiting response time; in the waiting response time, a return data receiving module in the self-adaptive module starts to work and is used for receiving return data of the front-stage equipment, meanwhile, the alternating communication control module selects a channel of the address line adri as a receiving function, and the two-way port control module switches the state of the address line adri into an input state and is matched with the return data receiving module to receive the return data of the front-stage equipment;
Further, if the adaptive module does not receive the backhaul data of the previous stage in the waiting state, the adaptive module sends a request instruction to the next stage, and enters the waiting state again, and waits for receiving the backhaul data of the next stage in the waiting state.
Specifically, a request instruction sending module in the self-adaptive module sends a request instruction to the latter-stage equipment, meanwhile, an alternate communication control module selects a channel of an address line adro as a sending function, a two-way port control module switches the state of the address line adro into an output state, and the request instruction sending module is matched with the request instruction to send a request instruction to the latter-stage equipment to complete the sending action of the request instruction, and after the request instruction is sent, the self-adaptive module enters a waiting state to wait for the back-stage returned data in waiting response time; and in the waiting response time, the return data receiving module in the self-adaptive module starts to work and is used for receiving the return data of the later-stage equipment, meanwhile, the alternate communication control module selects a channel of the address line adro as a receiving function, and the two-way port control module switches the state of the address line adro into an input state and is matched with the return data receiving module to receive the return data of the later-stage equipment.
In the process, when the device starts the self-adaptive first function, the sequence of sending the request instruction to the front-stage device or the back-stage device can be exchanged, namely, the request instruction can be sent to the front-stage first, and if no return data exists, the device sends the request instruction to the back-stage; the invention can send request command to the back-stage, if there is no return data, the device sends request command to the front-stage, therefore, when the LED cascade device is maintained, even if the first-stage device is damaged, the invention can send request command to the back-stage device to obtain corresponding address information, thereby realizing the maintenance of the first-stage device.
And step S30, the self-adaptive module receives the back data of the front stage or the back stage, checks the back data, and closes the self-adaptive first function after the check is successful.
As an implementation manner, in this embodiment, after the adaptive module receives the backhaul data in the waiting state, the adaptive module checks the backhaul data; if the verification of the returned data is successful, writing parameter information contained in the returned data into a programmable storage medium, and closing the self-adaptive first function; and if the returned data check fails, continuing to start the self-adaptive first function.
Further, according to the type of the request instruction, the parameter information contained in the returned data is also different.
If the transmitted request instruction is an addressing instruction, the address information of the data returned by the front-stage device is the address information of the front-stage device, and the address information of the data returned by the rear-stage device is the address information of the rear-stage device, the address step is subtracted from the address information returned by the front-stage device, so that the address information of the current position can be obtained, or the address information of the current position can be obtained by adding the address step to the address information returned by the rear-stage device.
If the transmitted request instruction is an adaptive parameter instruction, the device not only can acquire the address information of the current position according to the steps, but also can acquire other parameter information such as current gain, address stepping, lamp channel number and the like.
