Card pulling delivery mechanism of card issuing device

InactiveCN102750745ACompact and reliable structure layoutEasy to holdTicket-issuing apparatusComputer moduleEngineering
The invention relates to equipment such as an automatic ticket vending and supplementing machine and the like for track traffics and public venues, in particular to a card pulling delivery mechanism of a card issuing device, which is an inside core module of the automatic ticket vending and supplementing machine. The mechanism comprises two card pulling mechanisms, a back delivery mechanism, a front delivery mechanism, a read-write ticket outlet mechanism, a corresponding card pulling motor, a delivery motor, a synchronous wheel, a synchronous belt and a photoelectric sensor, wherein the two card pulling mechanisms, the back delivery mechanism, the front delivery mechanism and the read-write ticket outlet mechanism are arranged on the same special back plate, the corresponding card pulling motor, the delivery motor, the synchronous wheel and the synchronous belt are used for driving the two card pulling mechanisms, the back delivery mechanism, the front delivery mechanism and the read-write ticket outlet mechanism, the photoelectric sensor is used for controlling the motors and the synchronous belt to act, and the back delivery mechanism and the front delivery mechanism share a special driven idle pulley to form a delivery passage. The invention provides the card pulling delivery mechanism with the advantages that the open type is adopted, the size is smaller, the card pulling delivery mechanism is provided with two card pulling mechanisms, two delivery mechanism and one read-write ticket outlet mechanism, tickets can be fast issued, and the maintenance and the repair are easy.

Mobile communication micropower digital multipoint indoor coverage system

InactiveCN104936197ARealize multi-standard integrated coverageAchieving Dynamic and Effective CoverageNetwork planningDigital signal processingBasement
The invention relates to a mobile communication micropower digital multipoint indoor coverage system, including a multimode signal access unit, an expansion unit and a far-end unit. The multimode signal access unit adopts an optical fiber as a transmission medium to transmit a signal into the expansion unit, the expansion unit uses a category-5 cable or an optical fiber to transmit the signal into the far-end unit; the multimode signal access unit can be connected with eight expansion units at most, one expansion unit can be cascaded with another expansion unit, and one expansion unit can be connected with eight far-end units at most. The mobile communication micropower digital multipoint indoor coverage system provided by the invention realizes multi-system (2G/3G/4G/WLAN) signal integrated coverage, solves the problem of repeated construction of multiple networks, and has good expansibility; communication noise is greatly reduced through a digital signal processing algorithm, and transmitted power of a radio frequency signal is only 27dBm, which is environment-friendly; the device is small in size, can determine installation density according to actual needs, is low in installation cost and small in construction difficulty, and is suitable for occasions with a large signal demand quantity and special demands such as communities, elevators, public venues, basements, hospitals and so on.
