Embodiment Construction

[0017] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0018] In the present invention, the computer first sends status inquiry information to the adapter through the RS232 port to confirm that the adapter is powered on and the working status is correct. After the roll call information, a response message is sent to the bus with the CAN protocol, and after being received by the adapter, it is queued and sent to the computer through the RS232 interface to complete the node configuration plan information. The special software then completes the seat allocation according to the list of automatically selected experts, and projects them to the large screen through the projector. After the selection starts, the system automatically retrieves the relevant information of the reviewees from the associated database for discussion and preparation by experts, and the review progress is displayed on the big screen at an...

Abstract

The portable field bus-type voting system consists of special software and hardware. The hardware includes computer, projector, communication adaptor and several voting machines, the computer transfers the display information to the projector and performs bi-directional communication with the voting matchines via the adaptor. The present invention features the bi-directional communication between the adaptor and the voting machines via CAN field bus; and the cascade of the voting machine via two USB interfaces and the USB interface of the communication adaptor. The portable structure is favorable to mobile use; and the industrial CAN field bus structure makes the system fast, reliable anti-jamming, and has many other advantages.

Description

technical field [0001] The invention belongs to a computer management information system, in particular to a portable field bus type voting system. Background technique [0002] The evaluation of technical titles involves some reviewers reviewing the personal data declared by the evaluated personnel, and then voting to determine whether the evaluated personnel meet the qualifications for obtaining a certain level of technical professional titles. However, the existing voting systems all use manual voting and manual statistics; the evaluation and management information can only form manual electronic documents at most, which is not authoritative; the evaluated personnel do not have authoritative personal database information. Contents of the invention [0003] The purpose of the present invention is to provide a portable structure that can be conveniently installed in a small suitcase, which is convenient for mobile review; h...
