Abstract

The invention relates to a network clock synchronization device and system. The network clock synchronization device comprises an examination point time service server, an examination point core switch, an access switch, a clock terminal, an image acquisition unit and a monitoring upper computer, wherein the examination point time service server is connected with the examination point core switch,the examination point core switch is connected with the plurality of access switches, the access switches are connected with the plurality of clock terminals and the plurality of image acquisition units, and the monitoring upper computer is connected with the examination point core switch. Display information of the clock terminal is collected through the image collection unit and sent to the monitoring upper computer for character recognition, then the display information is compared with standard time, the abnormal clock terminal is found in time, feedback is timely, it is convenient for the system to rapidly process the abnormal terminal, and the system is worthy of vigorous popularization.

Description

technical field [0001] The invention belongs to the technical field of clock synchronization, and in particular relates to a network clock synchronization device. Background technique [0002] Large-scale examinations such as the college entrance examination, graduate entrance examination, civil service examination, and high school entrance examination have multiple test centers, and these test centers are widely distributed. For example, the college entrance examination is a unified examination covering the whole country. The strict organization of the examination requires strict time unification. This requires the introduction of a time synchronization system. The time synchronization system is a system that can receive an external time reference signal and output it according to the required time accuracy. A system of time synchronization signals and time information, which can align and synchronize other clocks in the network. Generally speaking, time synchronization is ...
