Embodiment Construction

[0065] The compact integrated redundant controller of the present invention will be described in detail below in combination with the embodiments and the accompanying drawings.

[0066] The compact integrated redundant controller (hereinafter referred to as the controller) is a single-board computer board based on 3UCPCI (Compact Peripheral Component Interconnect) technology, which integrates redundant control functions and system control functions. The controller uses Freescale (Freescale) high-performance processor MPC8245 as the main control CPU, and uses 128 megabytes of ECC (Error Correction Check, error detection and correction) memory. The controller adopts RS422 (RS422 is a standard protocol, the standard number is TIA / EIA-422-A) serial port and 100M Ethernet as the checkpoint protocol to realize the link. These two links form a redundant link and back up each other. . The controller uses PLD programmable devices to realize heartbeat protocol, slot power on and off, a...

Abstract

The invention provides a compact integrated redundancy controller and a controlling method thereof. The controller is provided with two controllers which have identical structure and can be used alternatively by displacing. Each controller is provided with a storage chip, a flash memory chip, a firmware chip and a programmable apparatus which are respectively connected with a main control chip; the controller is also provided with a first serial port transceiver, a second serial port transceiver, a PCI bridge piece and a network card controller. The serial port transceivers are connected witha CPCI connector by a RS422 serial port; the network card controller is connected with the CPCI connector by an Ethernet port; the PCI bridge piece is connected with the CPCI connector by a CPCI bus;the serial port transceivers are also connected with a maintenance serial port; a programmable apparatus PLD is also connected with the CPCI connector by a HA control signal. The methods comprise thestarting method of main / standby controllers, the method that a standby controller is upgraded into a main controller automatically and a check point protocol control method when the main controller and the standby controller are switched in a system. The controller and the method can upgrade the system controller of a traditional CPCI system into a double-redundancy standby system, which solves the hidden trouble that single-point failure can easily occur in a CPCI system controller.

Description

technical field [0001] The present invention relates to a redundant controller system. In particular, it involves a system controller that can upgrade the traditional CPCI system to a dual-redundancy backup system. The two physical controllers monitor and back up each other, thereby solving the hidden danger that the CPCI system controller is prone to single-point failure, thereby greatly A compact integrated redundant controller for improving the availability of a CPCI system and a control method thereof. Background technique [0002] Such as figure 1 As shown, the traditional redundant controller system adopts a 6U CPCI structure, which consists of two system controllers and two hot-swap controllers, occupying four CPCI slots. Mainly have the following deficiencies: [0003] 1. The plate type is large and requires a large space, which is not conducive to miniaturization and cannot be used in industrial environments with strict space requirements [0004] 2. The system ...
