Better, respectively comprise one in the monitor module of above-mentioned main system and the monitor module of standby system and monitor CPU, and power supply is powered separately, two monitor that CPU carries out exchanges data and synchronous by the high-speed bus on the backboard, two systems all carry out same program, and generally main system is devoted oneself to work, the running status of standby system real time monitoring main system, in case note abnormalities, just take over all functions of main system.
A kind of platform side door control device based on above-mentioned cold standby redundancy approach also is provided, and it comprises power module, monitor module, security logic arithmetic element and the safety relay output control unit module of 1+1 redundancyization; Its working method is as follows: the power module of the power module of A system and B system is active redundancy(-ce) each other, mode by parallel connection is embodied as other module hardware current-sharing power supply, arbitrary power module fault or when being removed, another power module still can guarantee to system normal power supply; The monitor module (being called standby system) of monitor module of A system (being called main system) and B system carries out exchanges data and synchronous by high-speed bus, two systems all carry out same program, when the monitor module of main system broke down, the monitor module of standby system will be taken over the work of main system; Security logic arithmetic element that A system and B system comprise and safety relay output control unit have only wherein one group to be in the state of working on power at synchronization, can switch to other one group of hardware to guarantee the normal operation of system by changeover switch when breaking down.
Better, the power module of above-mentioned main system and standby system, monitor module, security logic arithmetic element, safety relay output control unit module are designed to the form of plug-in unit, be installed on jointly in the subrack of 6U normal formula, undertaken interconnectedly between the plug-in unit by backboard, finish the mutual of information.
Better, respectively comprise one in the monitor module of above-mentioned main system and the monitor module of standby system and monitor CPU, and realized the independent power supply of power supply, two monitor that CPU carries out exchanges data and synchronous by the high-speed bus on the backboard, two systems all carry out same program, and generally main system is devoted oneself to work, the running status of standby system real time monitoring main system, in case note abnormalities, just take over all functions of main system.Supervision plug-in unit fault in A system and the B system or when being removed can't influence the control function of device to whole side door like this, and promptly door still can normally operation under the effect of security logic computing plug-in unit and safety relay output control plug-in unit.
Better, interchangeable between the plug-in unit with identical function of correspondence in A system and the B system.
Compared with prior art, make the whole system clear in structure in the time of high reliability that the utility model can assurance device and high availability, be simple and easy to usefulness, and be convenient to safeguard.
Description of drawings
