Embodiment Construction

[0021] In order to make the above objects, features and advantages of the present invention more comprehensible, specific implementations of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0022] The embodiment of the present invention proposes a terminal device bus-type cascading access control scheme based on the network+USB architecture. The scheme is based on the architecture of the network+USB. Equipment configuration, the upper computer and the first terminal device (terminal device 1) in the cascade are directly connected through a network cable, and the subsequent terminal devices at all levels are cascaded through USB. The upper computer only needs to enumerate the first terminal device, and the subsequent The enumeration of terminal devices (terminal devices 2-N) is directly completed by accessing the first terminal device, so the whole system architecture of this scheme is simple, with high communication speed ...

Abstract

The present invention relates to a terminal device access control system. The terminal device access control system comprises an upper computer and a plurality of terminal devices which are in cascade connection, the upper computer is connected with the first-stage terminal device of the plurality of terminal devices via a network, and the plurality of terminal devices are in the cascade connection via a serial bus. The present invention also provides an LED display system using the terminal device access control system. According to the present invention, the upper computer and the first stage terminal device are connected via the network, and the terminal devices are in the cascade connection via the serial bus, so that the system architecture can be simplified under the premise of guaranteeing the communication speed, the remote access and the long-distance transmission control can be supported, the browser operations can be simplified, and the cascade sort is flexible, and accordingly, the positioning and addressing to the terminal devices are convenient.

Description

technical field [0001] The present invention relates to the technical field of terminal equipment access control, in particular to a terminal equipment access control system and an LED display system. Background technique [0002] At present, in the field of LED display control, the access control scheme design of terminal equipment is mainly based on the bus type cascade structure. figure 1 It is a schematic diagram of the hardware architecture of a terminal device access control scheme using a bus-type cascade structure. from figure 1 It can be seen that the entire system architecture is composed of a host computer and a terminal device with host computer software installed. The host computer is only physically connected to the first terminal device (that is, terminal device 1) in the cascade. The host computer first enumerates the first terminal device. One terminal device, and then complete the search and enumeration of all terminal devices in the cascade through the f...
