Abstract

The invention relates to a practical drill examining device, in particular to an examining device applied to a ZPW-2000A automatic block system practical drill. The device comprises an upper computer and a lower computer which communicated with the upper computer through a serial port. The upper computer is provided with software which can set examination questions and automatically score according to maintaining conditions of students. After the examination questions are set by the upper computer, data and an order are automatically transmitted to the lower computer through serial port communication. The lower computer responds to the upper computer through serial port communication and comprises a serial port communication module, a central control module, a relay drive module and a relay interface module. The examining device has the advantages of being convenient to use, fair and balanced in examination, good in expandability and transferability, capable of collecting general data, high in efficiency, convenient to debug, maintain and overhaul, low in cost, high in practicability and popularization value and the like.

Description

technical field [0001] The invention relates to a practical training assessment device, in particular to a practical training assessment device for a ZPW-2000A type automatic blocking system. Background technique [0002] The ZPW-2000A non-insulated frequency-shift automatic blocking system belongs to the rail transit signal control system. It passed the technical appraisal of the Ministry of Railways in 2002 and has been popularized and applied throughout the railway. When railway signal workers are engaged in the maintenance and maintenance of railway signal equipment, they must master ZPW- Installation and maintenance skills of 2000A automatic blocking system. Therefore, the application of ZPW-2000A automatic block training system has been more and more widely used in the personnel training and curriculum setting of railway signal related majors in various railway vocational colleges. [0003] The hardware composition of the above-mentioned training system is exactly the...
