Embodiment Construction

[0027] The technical solutions of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0028] Such as figure 1 As shown, the present invention provides a system for realizing address sequence recognition of embedded devices. In this system, generally all devices are connected through field bus, such as figure 1 "Master", "1# slave", "2# slave" and "3# slave" can be considered as devices in the system. In order to realize the address sequence recognition of the present invention, the present invention also enables each device to be serially connected in series through its own interface unit 210 to form an address control signal transmission line 220 for transmitting slave strobe signals, and between every two devices Cascading through a controllable connection unit 230, the control end of each controllable connection unit 230 is connected to the delay control signal output end of a device, and the controllable connection uni...

Abstract

The invention discloses a device, a method and a system for realizing address order identification of an embedded device. In the system, all devices are connected through field buses, and are connected in series in turn through interface units arranged on the devices to form an address control signal transmission line for transmitting a slave strobe signal; moreover, every two devices are in cascade connection through a controllable connection unit, and the control end of each controllable connection unit is correspondingly connected with the output end of a delayed control signal of one device; and each controllable connection unit is used to keep or cut off the connection of a device and the address control signal transmission line according to the delayed control signal output by the device connected with the unit. The device, the method and the system solve the problems of bus conflict or identification error, and the like caused by the address loss of the device, realize automatic order identification and allocation of the address during putting the device into service, and are suitable for a network in which no communication is carried out among slave devices.

Description

technical field [0001] The invention relates to a technology for realizing automatic sequence recognition of embedded device addresses, in particular to a device, method and system for realizing the sequence recognition of embedded device addresses through field bus communication and serial wiring. Background technique [0002] With the development of technology and the improvement of living standards, more and more electronic products such as industrial control, medical treatment, communication, and consumption are increasingly intelligent, and embedded systems with microprocessors as the core are increasingly widely used. On-site networking and management of intelligent equipment has also become a focus of embedded applications. Users can configure, manage and monitor it through the intelligent interface provided by the device, such as serial port, parallel port, Ethernet port, etc. The high-speed Ethernet interface based on the complex TCP / IP protocol is the future devel...
