Problems solved by technology

In the traditional rail logistics system that adopts a centralized control method, the controller is too large, and local failures will affect the normal operation of the entire system, resulting in poor reliability.
A controller needs to complete many tasks such as data collection, data processing, and on-site control, and each specific control task in the entire system must be issued by the controller. The real-time performance of the system is poor, and it is difficult to expand or reduce the system once it is completed. System function, poor system flexibility

Embodiment Construction

[0038] like figure 1 As shown, the railway transportation partition dispatching system of the present invention adopts the mode of centralized dispatching and decentralized control, which includes a general controller, a regional controller, a monitoring terminal, a barcode scanner and a motor drive control unit.

[0039]The general controller adopts programmable logic controller PLC, which mainly performs the centralized dispatching of the whole system; the general controller communicates with the regional controllers in each region, rail logistics trolleys and rail switchers through the Modbus-TCP communication bus. The general controller is the dynamic scheduling, control and command center of the medical rail logistics transmission system, which receives touch terminal scheduling request information from monitoring terminals and work stations, and completes all scheduling tasks of the entire system, including shunting, storage, and departure, etc. . The real-time status p...

Abstract

The invention relates to a partition scheduling system for rail transportation. The partition scheduling system comprises a master controller, region controllers, a monitoring terminal, a working station, bar code scanners and a motor driving control unit. The master controller is respectively connected and communicated with the regional controllers, rail logistics trolleys and rail switches of all the regions; the master controller is also respectively connected and communicated with the monitoring terminal and the working station; the region controllers are respectively connected and communicated with the rail logistics trolleys and the rail switches in the regions; the bar code scanners are arranged on the rail logistics trolleys and store the path label information to trolley controllers of the rail logistics trolleys, and the trolley controllers are connected and communicated with the master controller; the motor driving control unit comprises a trolley motor driver and a rail switch driving motor; the trolley motor drivng unit is connected and communicated with the trolley controllers, and the rail switch driving motor is connected and communicated with the region controllers. The system is reasonable in conception, high in operation reliability, high in real-time performance, flexible to use and capable of effectively improving the rail transportation efficiency.

Description

technical field [0001] The invention belongs to the technical field of medical rail logistics, and in particular relates to a rail transportation partition dispatching system. Background technique [0002] With the development of society and economy, the rail logistics transmission system has gradually expanded from other fields to the medical field, resulting in the Medical Track Vehicle System (MTVS for short). The special environment of the hospital puts forward higher requirements for the real-time performance, reliability and flexibility of the rail logistics transmission system control system. In the traditional rail logistics system using centralized control, the controller is too large, and a local failure will affect the normal operation of the entire system, resulting in poor reliability. A controller needs to complete many tasks such as data collection, data processing, and on-site control, and each specific control task in the entire system must be issued by the...
