Abstract

The invention discloses a method, system, device and equipment for controlling a serial device. Main control equipment is annularly connected with a plurality of controlled devices in series by a main control serial device and controlled serial devices. The control method comprises the following steps: sending control signals to the controlled serial devices at the downstream by the main control serial device; when the controlled serial devices receive the control signals sent by the main control serial device or the controlled serial devices at the upstream, analyzing downlink data in time slots corresponding to the controlled devices to which the controlled serial devices belong from the control signals, and then forwarding the downlink data to the controlled devices to which the controlled serial devices belong; writing uplink data in the corresponding time slots, and sending the uplink data to the controlled devices or main control serial device at the downstream, wherein the uplink data are sent to the main control equipment by the controlled devices to which controlled serial devices belong; and after the main control serial device receives the control signals, forwarding the control signals to the main control equipment to acquire the uplink data which are carried in the control signals and sent by each controlled device. The annular serial connection of the serial devices is used to realize management control of the main control equipment for a large number of controlled devices; and in addition, the structure design is simple and convenient to realize.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a serial device control method, system, device and device. Background technique [0002] Most of the existing switching devices adopt serial port management and control, and this control interface adopts point-to-point transmission mode. Therefore, generally, a PC can only be connected to one switching device to manage and control it, which undoubtedly brings inconvenience to large-scale switching device management and control. There are two ways to solve this problem in the prior art: [0003] One is to use a serial port router to realize the control and management of serial port devices. In this way, the PC is connected to a dedicated router with a network cable, and the serial ports of multiple switching devices are also connected to this router through special serial port cables. The conversion chip converts the serial port data into Ethernet data and sends it to ...
