A kind of cell controller for subway shield door
Technical field
The utility model relates to a kind of cell controller, refers to especially a kind of cell controller for subway shield door.
Background technology
Subway shield door is a high-tech product that integrates the subjects such as building, machinery, material, electronics and information, is used in subway platform.Shield door separates platform and train operation zone, by control system, controls its automatic unlatching.
Being perfectly safe when having ensured that train, passenger are out of the station, subway platform is installed shield door minimizing Si Ji lookout number of times significantly, alleviated driver's mental burden, and can effectively reduce the loss of the cold and hot gas of platform that cross-ventilation causes, reduce the impact of the noise of train operation generation on station, comfortable waiting environment is provided, there is energy-conservation, safety, environmental protection, the function such as attractive in appearance.
Cell controller is the key core parts of screen door, and as described above, its Main Function is the open and close door order that processing signals system (SIG) system is sent, and instruction is sent to sliding gate.The feedback states relay receives the mode of operation of signal system (SIG), local control panel (PSL), integrated backup panel (IBP) and slave relay unit, and feeds back to PLC with the form of switching value, so that PLC reads and be uploaded to comprehensive monitoring system.
At present, cell controller in the screen door control system that subway station adopts mostly is import brand, and control method has the single-chip microcomputer ic-type, and relay and single-chip microcomputer are welding manner and are connected on the monoblock circuit board, single-chip microcomputer reads the state of relay, and great majority are back opening door.
Also have in addition relay to be attached on base with inserting mode, base directly is fixed on one and installs on backboard, sets out line terminals around relay base, and the wire on terminal is connected with external unit with host computer by wire casing or direct fly line.
The ic-type cell controller is by safety relay, feedback states relay and monitor that the contra credit single-chip microcomputer all is integrated on one or two circuit boards, and casing back pullout (BPO) mode makes the duty that can't directly observe each components and parts in the work engineering.If the maintain and replace device must be dismantled the monoblock circuit board, can't realize on-site maintenance, very inconvenient, and the monoblock circuit board is expensive, and maintenance cost is high.
The cabling of plug-in relay formula cell controller is by wire casing or direct fly line, comparatively in disorder.And plug-in relay does not have working station indicator, can not observe intuitively its action situation.
In order better to understand the utility model, at this, we have provided the table of comparisons of specific term Chinese and English abbreviation:
