Description
Technical Field
The invention relates to a circuit and a method for identifying slot position and disk type of a hardware board card in a wave distribution electric cross transmission equipment system, belonging to the field of identification communication equipment.
Background
With the development of the communication industry, the demand for a large-capacity broadband network is increasing day by day, the development and research of a high-density and high-speed optical fiber transmission system are more and more urgent, and a large-capacity wavelength division electrical cross transmission device gradually becomes a mainstream device form of optical communication transmission because the large-capacity wavelength division electrical cross transmission device can well meet the balance of performance and power consumption of operators. The advanced telecom computing platform (ATCA) standard is commonly adopted by communication equipment manufacturers at present, meets the requirements of an open standard hardware architecture platform, and provides a high-density and high-performance service system for carrier-level telecom applications. The hardware comprises a machine frame and a single board (including a processor board, a switching board and the like). Generally, a stable platform function and a fixed platform function are implemented in a hardware single board, and a flexible service function and an application function are implemented in a software manner. Along with the increase of the capacity, the number of the hardware single boards is more and more, various communication and management buses are required to be connected to each single board in the system architecture design, the position of each single board in the subframe is a slot position, and the slot position is distinguished depending on the hardware level, so that the control unit can correctly find each single board through the bus to complete the issuing of the monitoring configuration command and the reporting of the alarm. As shown in the common device bus slot management in FIG. 5, the control unit accesses the single boards at different positions through the management bus, and the slots 1-256 total 256 hardware slots correspond to 256 addresses and range from 0x00-0xFF (16-ary system).
The single board framework is composed of a low-power-consumption hardware system carrying an embedded software system, along with the more refined classification of the service level, the urgency is also highlighted for the distinguishing requirement of the single-disk service level, and as the structure of the hardware system is fixed, in order to meet the trend of software diversification, the hardware needs to provide a set of method for classifying according to the requirement, so that the software can be adapted to different functions, and the method is a single-disk type identification function. At present, the single board hardware is generally controlled by a central processing unit (cpu) (mcu) module, and is assisted by a large-scale logic device such as an FPGA or a CPLD module to perform port management. The initialization characteristic of the embedded operating system determines that before the firmware is downloaded, namely, at the initial stage after the single board is powered on, the hardware identification is required, so that the software can enter different branch module units, and different firmware stored in the memory can be selected and downloaded according to the requirements of different service types.
At present, slot position identification modes existing on a single board are realized by combining a backboard circuit, and then are distinguished through bus addresses. If there are 32 slots, the address is 4 th power of 2, and a 4-bit address bus is needed, and if there are 64 slots, a 5-bit address bus is needed, and so on.
The idea is to put a dialing unit on the board, and read the value of the dialing unit to determine the initialization type before initializing and downloading the firmware. The dialing unit is composed of some switch circuits, is arranged on a single board and needs to be set through a manual dialing process before leaving a factory, and has the defects that certain board layout area and hardware IO (input/output) resources are occupied, and the flexibility and the expandability are poor.
The second idea is a software and hardware combination mode, which is realized by using the existing IO plug-in similar three-eight decoder as a logic circuit, the output logic is controlled by simple input logic, and more identification types and numbers are expanded by realizing the amplification of addresses.
In summary, the slot position identification and the type identification of the existing veneer generally belong to two different functional modules, which are realized by two independent hardware circuits, the software hardware design aspect is comparatively split, the two circuits occupy more layout space and more input/output port resources on the whole veneer, and the veneer is not economical when considering the factors of the large-scale production cost.
