All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
For the convenience of understanding the present embodiment, the technical terms designed in the present application will be briefly described below.
Chip refers to Integrated Circuit (IC), or microcircuit (microcircuit), microchip, and chip/chip (chip) in electronics, which are a way to miniaturize circuits (mainly including semiconductor devices, including passive components, etc.) and are manufactured on the surface of semiconductor wafers. Depending on whether the circuit is analog or digital, it can be divided into analog integrated circuits, digital integrated circuits and mixed signal integrated circuits (analog and digital on one chip).
Communication chip (Communication chip)
The communication address has the capability of communicating with other equipment with the same communication function after a communication circuit is designed in each equipment in the communication engineering, however, in the process, the communication address of each communication equipment must be configured to ensure that the communication address of each equipment is unique in the whole communication loop, and the address is the communication address of the equipment.
The board card is a kind of printed circuit board (PCB for short), and has a plug core when being manufactured, and can be inserted into a slot of a main circuit board (motherboard) of a computer to control the operation of hardware, such as a display, a collection card and other devices, and after a driver is installed, the hardware function of response can be realized. In the field of computers, a mainboard, a sound card, a video card and the like are collectively called board cards. The board cards are divided into four types, namely an ISA bus board card, an EISA bus board card, a PCI bus board card and an AGP bus board card.
Cascading, which means that a plurality of devices are connected in a line in the form of hands, is generally called cascading. In computer science, the mapping relation among a plurality of pairs of lines is indicated, and the cascade relation among data is established to improve the management efficiency.
After introducing the technical terms related to the present application, the following briefly introduces the application scenarios and design ideas of the embodiments of the present application.
In the communication engineering, a plurality of devices are connected in sequence, and each device has the same communication function with other devices after relating to a communication circuit. In this process, the communication address of each communication device must be configured in turn. To ensure the patency of the entire communication loop, the communication address of each device must be unique.
However, the devices are designed to have the same communication address. After multiple devices are powered up in cascade, problems arise: because the respective addresses of a plurality of devices are not unique, the signal transmission is disordered, and the whole communication loop cannot be normally used.
In the related art, in order to solve this problem, it is necessary to detach all the devices in the entire communication loop, only one device is reserved, and then the communication address is set for the other devices at a time. Such operation is particularly troublesome for highly integrated multi-board chassis devices.
Therefore, the application provides a method for automatically writing in the communication address and cascade equipment so as to improve the convenience of writing in the communication address when multiple pieces of equipment are cascaded.
