Problems solved by technology

In order to reduce the bit error rate, and considering the processing capability of the main control device A, it is not suitable for synchronous control of multiple devices, which limits the number of controlled devices and inevitably limits the number of split screens, making the number of multi-screen displays limited. Limitation, reduced user experience

Embodiment Construction

[0015] like figure 2 As shown, the main control device A and N controlled devices (S 1 …S N ) connection mode, the master control device A is connected with N controlled devices connected in sequence, each of the above devices can send commands to the next-level device, and each has a return channel to return the command to the upper-level device, and finally The next-level device of a controlled device is the master device, and the return channel of the master device is connected to the last controlled device.

[0016] like image 3 As shown, a processing method of a cascade control command of the present invention comprises the following steps:

[0017] Step 1. The master control device A sends a command combination to the sequentially connected N controlled devices, and the command combination includes all the commands that the N controlled devices need to execute;

[0018] Step 2. The command combination sent by the master device A is first sent to the first controlle...

Abstract

The invention relates to a cascade control command processing method. A master control device is connected with N controlled devices which are connected in sequence, each device can send a command to a next level device and is provided with a return channel for returning the command to an upper level device, the next level device of the last controlled device is the master control device, the return channel of the master control device is connected to the last controlled device, each device is provided with a command processing mechanism and an active control mechanism per se, data volumes completely processed by the master control device are decomposed to each cascaded controlled device, and the controlled device retains the executive command of the device and issues the command not processed by the device to the next level device. According to the cascade control command processing method provided by the invention, a single control system is converted into a plurality of independent control system to dispersedly process commands, so that the command execution efficiency can be greatly enhanced, the more devices are cascaded, the higher the command issue efficiency is, and the better the linkage of multiple devices is.

Description

technical field [0001] The invention relates to a processing method for cascade control commands. Background technique [0002] With the increasing maturity of LED technology, large-scale LED screens are gradually being promoted. In the process of promoting large-scale LED screens, in order to realize the multi-screen display of LED large screens, the infinite creative space of art workers can become In reality, people have developed LED video processors that support multi-screen display. [0003] Various industries such as security monitoring, administrative management, military command, exhibition display, scientific research and education require multi-screen display functions in the application of video processors. The existing LED video processors in the market can generally only support four-split screens, which greatly restricts on-site construction wiring and creativity, which in turn causes great application troubles for users and cannot meet the actual needs of us...
