The invention is further described with reference to the following practical application and the accompanying drawings:
referring to fig. 1, a hardware chassis of a standard ATCA architecture includes a main control board 1, a clock board 2, a fan control board 3, two cross boards 4 and twelve service boards 5, where the main control board 1, the clock board 2, the fan control board 3, the two cross boards 4 and the twelve service boards 5 are connected to each other through a line Switch chip; the main control board card 1 is provided with a zynq chip, and the chip is connected with a PC through a network to realize data communication.
The user can control the equipment by using a client software control system on the PC to realize the service function, the software control system is positioned in a zynq chip on the main control board card, and the operating system is a linux system. The boards are connected through a line Switch chip in a network mode to achieve data communication, and a connection relation diagram between the boards is shown in fig. 2.
The software control system receives the command sent by the PC, and controls the equipment to realize the corresponding function. The main thread of the network server of the control system is provided with two network servers, namely a first server and a second server, wherein the first server is respectively connected with PCn threads through an Ethernet, and the second server is respectively connected with two cross board card 4 threads and twelve business board card 5 threads through the Ethernet. Because the zynq chip supports two network ports, two IP addresses can be set, so the software control system can establish two network server ends, one server establishes connection with a PC, and the other server connects with a board card for realizing specific service in the equipment. When a client of a PC applies for network connection to a server in the software control system, the software control system receives the connection request, establishes a thread for the connection request, is used for receiving and transmitting data with the PC, and stores network information (such as an IP address, a port number and the like) of the client. When a service board card is inserted into the device, the device applies for network connection to another network server of the software control system, the software control system firstly receives a request of network connection and sends routing data stored by the software control system for the board card, so that the problem of service function loss caused by the board card plugging and unplugging can be solved. Then, the software control system establishes a thread for the board card for carrying out network communication with the board card and receiving and transmitting data. An architecture diagram of the software control system is shown in fig. 3.
After the software control system establishes network connection with the PC and the board card, two instruction queues are created, one instruction queue stores instruction data sent by the PC, and the other instruction queue stores instruction data sent by the board card. For each instruction, according to a predefined protocol, a command number is parsed, and different data processing functions are selected according to the command number, so as to realize corresponding service functions, as shown in fig. 4.
The control system performs data communication on the upper PC and the lower PC through a network, and performs communication on the lower PC and the hardware board, the zynq chip is set to a mode supporting two IP addresses, one IP address is selected to perform communication with the PC, a network server is established, the other IP address is selected to perform communication with the hardware board, and the other network server is established.
When a PC client sends a connection application, a thread is newly built on the client in a control system and is used for processing a command sent by the PC; when a hardware board card is inserted into a case, the hardware board card is used as a client to send a network connection application to the software, and after receiving the connection application, a control system firstly sends routing data to be configured to the board card, so that the board card is recovered to the state and the function before the last power failure, and then a thread is created for the board card to process the communication with the board card.
Waiting for the command sent by the PC end, storing the command into an instruction queue, carrying out new creation, deletion and initialization on the function of equipment routing according to the command number, calculating routing data, and sending the routing data into a board card of hardware so as to enable the equipment to realize corresponding functions.
The main service function of the software control system is to create/delete routes, and the specific processing process is as follows:
(1) The method comprises the steps that firstly, a PC end initiates operation, a routing mode is an A board card B port-C board card D port, a software control system takes out the instruction from an instruction queue, analyzes a command code in a data packet head, and if the command code is a command code of a newly-built/deleted route, enters a processing function of the newly-built/deleted route;
(2) Analyzing route data in a data packet, wherein the route data comprises the number of routes, the serial number of an input board card input port and the serial number of an output board card output port of each route, judging whether the values of the serial numbers are in a correct range, if the values are wrong, marking the route as wrong route, if the values are wrong, calling a routing algorithm based on the equipment architecture in a software control system, calculating data needing to be written into a bottom board card, and if the calculation fails, indicating that the route has a problem, and marking the route as failure;
(3) After the calculation of the routing data is finished, the routing data is issued to the boards (the boards refer to boards with the calculated routing data changed), then the return results of the board configuration routing data are waited, if the return results of the boards are failure, a routing list of failure of PC configuration and reasons of errors are reported, and the routing data are restored to be the results of not carrying out the route calculation; if the board card does not return the configuration result within the specified time, the equipment is considered to be abnormal, the board card which does not return the configuration result on time and the route which is not successfully configured are returned to the PC, and meanwhile, the route data is restored to a value when the route configuration is not performed; if the results returned by the boards are successful, the configuration route is considered to be successful, the result of successful configuration route is returned to the PC, and the route data is stored and written into the file for the PC to inquire the route.
According to the above procedure, the operation of creating/deleting a route can be realized, as shown in fig. 5 in particular.
The software control system is communicated with the PC and the board card in the actual use process in a multithreading mode, so that the management function of the multi-board card can be achieved, the rapidity and accuracy of data communication of the multi-board card are achieved, the problem of concurrency and synchronization is solved, the equipment can be conveniently and stably managed, the configured result can be returned within three seconds when thousands of routes are newly built/deleted, and the function of Tb/s-level signal exchange of the equipment can be well controlled.
