Method, device and system for acquiring module identifier

Abstract

The invention discloses a method, a device and a system for acquiring a module identifier. The method comprises the following steps that: a module acquires a signal containing rack information and a signal containing slot position information from a single board inserted into the module; and own identification information is obtained by utilizing the rack information and the slot position information. According to the application, a series of problems that a large amount of manpower and materials are consumed, the number of parallel buses is limited by a peripheral component interconnection (PCI) standard, the identification efficiency is poor and the like are avoided, and the identification of the module is realized in a simple, convenient and quick manner.

Description

technical field [0001] Embodiments of the present invention relate to the field of communication technologies, and in particular, to a method, device and system for acquiring a module identifier. Background technique [0002] The modules in the power supply system are usually interconnected by a serial communication bus to realize mutual data interaction, and communicate with the monitoring equipment through the bus to realize remote control, telemetry and remote signaling of each module. If the monitoring equipment and modules For communication, it is necessary to distinguish each module by identification. [0003] In related technologies, the identification of the module is often obtained by burning the slot address number and then reading the slot address number, or pulling up different address lines to obtain the slot address number to obtain the module identification, or adding a dial The switch generates the corresponding binary number representing the address of the ...

Problems solved by technology

[0004] However, among these identification methods, the method of burning the address number including the slot will consume a lot of manpower because of the need to perform the burning operation; the method of pulling up different address lines needs to rely on the Peripheral Component Interconnect (PCI) Parallel bus and system scanning are required, so it is limited by the number of PCI parallel buses and the marking efficiency is poor; the method of adding a dial switch needs to rely on the number of switch digits of the dial switch. The more digits of the dial switch, the digital control The more input and output (Input / Output, IO) port pins the controller uses to detect the switch position, the larger the volume of the digital controller will be, so the required material cost will be greatly increased
