Technical field
The utility model relates to a kind of communication interface switching device, and relating in particular to a kind of transport mode conversion point-to-point arranged side by side with apparatus for controlling elevator is the old ladder transformation switching device of tandem transmission mode.
Background technology
The chauffeur in the parking lot in the most old elevator in the past and IND display device are point-to-point transmission modes arranged side by side (RS232), and the chauffeur in the parking lot of present apparatus for controlling elevator, show the mode all adopt tandem transmission (RS485), like this, because the difference of equipment on transmission mode, when the transformation of old elevator, chauffeur box, display device, button and the cable of old elevator just must more connect, unified transmission mode, thereby cause cost too high, be unfavorable for market competition.
The utility model content
Technical problem to be solved in the utility model is: provide a kind of old ladder that point-to-point transmission mode arranged side by side and tandem transmission mode are transferred to transform switching device, realize old Retrofit of Elevator, reduce the cost of transforming.
The technical scheme that its technical matters that solves the utility model adopts is:
A kind of old ladder is transformed switching device, is made up of signal source interface, RS485 communication interface, power interface and TP communication interface, and it is characterized in that: described signal source interface is connected supervisory keyboard with the RS485 communication interface; Described power interface connects power supply; Described TP communication interface connects electric life controller.
Further, described old ladder is transformed switching device and is provided with the EIO expansion interface that is used to connect expanding unit.
Further, described old ladder is transformed switching device also can increase the expanding unit that several are used to increase the control capacity.
Further, described expanding unit is made up of power interface, EIO expansion interface and TP communication interface; Described power interface is connected with the EIO expansion interface with the power interface that EIO expansion interface and described old ladder are transformed switching device.Described TP communication interface and corresponding electric life controller connection.
Old ladder of the present utility model is transformed switching device the transfer platform of a transmission mode arranged side by side with the tandem transmission mode is provided, and makes between each controller of elevator and can better integrate, and moves.
Description of drawings
Further specify the utility model below in conjunction with the drawings and specific embodiments.
Fig. 1 is the hardware connection layout of the utility model switching device embodiment.
Embodiment
