(7) passenger's emergency alert function
Requirement can receive and upload the signal of passenger's emergency alarm to the on-vehicle safety computing machine.
Control for above 7 aspect security functions must be perfectly safe, and the inefficacy of vehicle-mounted control will directly cause the out of control of vehicle safety function, thereby influence the safety of Vehicular system.
The basic vehicle-mounted control scheme of present German TR08 vehicle is:
First bus and trailer respectively dispose the fail-safe computer of 1 train level, and fail-safe computer adopts three to select two fault-tolerance architecture.Every joint car has disposed the vehicular control unit of 2 vehicle grades.They and fail-safe computer transmit signal by the mode of bus cascade.Vehicular control unit directly is connected with low layer equipment downwards.Determine the master control fail-safe computer by the mode of " firsting impressions are strongest ", i.e. the fail-safe computer of train operator elder generation login is the master control fail-safe computer.Control command to underlying device is always sent by the master control fail-safe computer, is delivered to the bottom controlled plant by cascade bus and vehicular control unit.The status signal of underlying device always is sent to the on-vehicle safety computing machine of first bus by vehicular control unit and cascade bus.
This scheme can satisfy vehicle-mounted control requirement generally speaking, but there are the following problems: 1. the master control fail-safe computer is to determine by the mode of manual entry, that is to say, under the condition that the master control fail-safe computer lost efficacy, ownership can not switch to another fail-safe computer automatically real-time, and this will cause the out of control fully of vehicle safety function; 2. be subjected to the restriction of its vehicular control unit circuit layout, the status signal of underlying device can only be sent to the on-vehicle safety computing machine of first bus, so behind the on-vehicle safety computer failure of first bus, operation control system can't obtain the status signal of vehicle safety function.
Summary of the invention:
The technical problem to be solved in the present invention comprises:
1. guarantee that by the synchronized operation technology ownership can switch automatically in real time between first bus fail-safe computer and trailer fail-safe computer, we claim these characteristics redundant for heat;
2. by the bidirectional bus cascade circuit, realize the bi-directional of underlying device status signal, guarantee that the head and the tail fail-safe computer all can obtain the safe condition signal of underlying device;
3. pass through the electrical isolation circuit, the control process of vehicle control syetem is met " fault---isolate " principle, the fault of promptly a certain bottom function device can not have influence on other bottom function device by vehicle control syetem.
Technical solution of the present invention:
A kind of high-speed maglev train vehicle hot-redundant vehicular control system, dispose the train level first on-vehicle safety computing machine and the second on-vehicle safety computing machine respectively at first bus and trailer, every joint car disposes two vehicle grade first vehicular control units and second vehicular control unit, its characteristics are that every joint car has also disposed a cable distribution unit, this cable distribution unit one end connects first vehicular control unit and second vehicular control unit, the other end connects the bottom function device, comprises suspension, guiding, braking, power supply, car door, fire is handled, the function device of passenger's emergency alarm; And corresponding first vehicular control unit between the adjacent vehicle is connected in the mode of first cascade bus with second cascade bus respectively with second vehicular control unit; First vehicular control unit of first bus also links to each other with the first on-vehicle safety computing machine with second vehicular control unit, and first vehicular control unit of trailer also links to each other with the second on-vehicle safety computing machine with second vehicular control unit.
Above-mentioned on-vehicle safety computing machine adopts three to select two fault-tolerant system configurations, and carries out synchronized operation, automaticallyes switch between the two on-vehicle safety computing machines.
Have photoelectricity and electrical isolation between above-mentioned bottom function device and the cascade bus.
