Problems solved by technology

However, the display device of the existing medicine dispensing machine is generally controlled by a single-chip microcomputer (microprocessor MCU), which makes the counting signal need to be level-converted first, converted into a signal that can be recognized by the MCU, such as a TTL level signal, and then passed through the MCU. Send to the digital tube to display the counting result
This method increases the conversion time, and it is easy to cause the transmission burden of the conversion circuit during the conversion, resulting in data loss or delay, and the data cannot be displayed in real time

Abstract

The invention provides a display device of a medicine counting machine. The display device is used for displaying counting results of the medicine counting machine. The display device comprises an interface unit, at least one latch decoder and at least one nixie tube, wherein the interface unit is connected with an output end of a programmable logic controller (PLC) of the medicine counting machine, a signal of the PLC is transmitted to a binary coded decimal (BCD) code input end and a latch signal end of the latch decoder, and a decoding output end of the latch decoder and a data input end of the nixie tube are connected. By means of the display device of the medicine counting machine, the counting signal of the PLC can be directly processed, and the counting results can be real-timely and accurately displayed.

Description

technical field [0001] The invention relates to a display device for a medicine dispenser. Background technique [0002] The medicine dispensing machine is a common equipment in the automated pharmacy, which can be used for the inventory and counting of the number of medicine particles, the counting of medicine subcontracts and other aspects. The counting mechanism of the medicine dispenser is usually controlled by a PLC (programmable logic controller) to obtain a serial counting signal. However, the display device of the existing medicine dispensing machine is generally controlled by a single-chip microcomputer (microprocessor MCU), which makes the counting signal need to be level-converted first, converted into a signal that can be recognized by the MCU, such as a TTL level signal, and then passed through the MCU. Send it to the digital tube to display the counting result. This method increases the conversion time, and it is easy to cause the transmission burden of the c...
