Abstract

The invention discloses an intelligent pharmacy control device which comprises a TMS320F28335 series DSP (digital signal processor), an EPM7128STC series CPLD (complex programmable logic device) and a printed circuit board, wherein the DSP and the CPLD are connected through the printed circuit board. The TMS320F28335 series DSP comprises three serial ports and are configured to form an RS-485A, an RS-485B and an RS-485C through MAX485 chips, wherein the RS-485B is connected with a pharmacy information management system, the RS-485C is connected with a human-computer interface system, and the RS-485A is used as a debugging interface to be reserved for developers to use. The TMS320F28335 series DSP is configured to form three PWM (pulse-width modulation) signals which are used for driving three stepping motors serving as intelligent pharmacy executive mechanisms respectively. The EPM7128STC series CPLD is provided with three SSI (server side include) interfaces which are used for acquiring position information of an absolute value encoder and signals of a positioning detection device and feeding acquired relevant data back to the DSP through the printed circuit board. The CPLD is responsible for data acquisition, the DSP is responsible for logic dispatch, and the CPLD and the DSP are closely cooperated with each other and linked with other subsystems, so that the problem of control of an intelligent pharmacy can be solved.

Description

technical field

[0001] The invention belongs to a pharmacy control device for distributing and supplementing medicines. The pharmacy control device is not only suitable for high-density prescription processing in large and medium-sized pharmacies, but also suitable for distributing medicines in small pharmacies such as community hospitals. Background technique

[0002] At present, the implementation methods of a motion control system or motor control system mainly include the following:

[0003] 1. A motion control system established by analog circuit hard wiring. The early motion control system is generally an analog control system composed of discrete components such as operational amplifiers and hard-wired. Its advantages lie in: through real-time processing of input signals, high-speed control of the system can be realized; The sampling frequency, so the precision of the controller is higher and has a larger width.

[0004] However, compared with the digital system, it...
