Detailed Description
The technical solution of the present invention is further explained with reference to the accompanying drawings and specific embodiments.
Referring to fig. 1 to 3, the present invention provides an automatic addressing method for display screens, which includes 32 display screens, wherein each display screen is connected with a rear connector 7 by a front connector 6 two by two. Each preceding-stage plug connector can form a complete power supply loop with input voltage; each front-stage incoming-circuit connector and each rear-stage connector are separated by a power switch device, and the on-off of the devices is controlled by the information processor 3.
The display screen enters an addressing state in the process after being powered on, the display screen detects whether the display screen is subjected to addressing or not in the addressing state, and exits the addressing state if the display screen is subjected to addressing; if the addressing is not carried out, monitoring an address broadcast instruction, and modifying the address number of the self as a monitoring address when the broadcast address number is monitored; and after the display screen completes the steps, the power switch device is turned on to complete the connection between the rear-stage plug connector and the front-stage plug connector of the current display screen.
In the automatic addressing process, a first display screen in the system is firstly electrified to address the display screen, then a power switch of a rear-stage plug connector is turned on, and an addressing state identifier is modified; the second display screen connected with the first display screen at the later stage is in a power-on state at the moment, after waiting for a period of time, the control main board sends a second programming instruction, and the second display screen can address the second display screen; the serial system can sequentially complete the addressing work of all the display screens connected in the later stage according to the principle.
After the display screens are powered on, each display screen performs the process shown in fig. 4 once, and the whole series system completes the addressing operation, which will be described in detail with reference to fig. 4.
Step1, electrifying the display screen, and setting the default addressing state as unaddressed;
step2, the main controller issues an address addressing instruction according to a fixed time interval, and an address number is increased by one by default every time;
step3, the information processor judges the current addressing state, if the current addressing state is not addressed, the information processor receives an addressing instruction for addressing, and if the current addressing state is addressed, all subsequent addressing instructions are ignored;
step5: turning on a power switch device of the current display screen to enable the front-stage connector and the rear-stage connector to be conducted and supply power to the next-stage display screen;
step6: repeating the steps 2-5 to complete the addressing process;
and after all the steps are finished, the addressing operation of a single display screen is finished, and when each display screen in the series system executes the operation, the addressing operation of each module can be finished.
