Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of method showing astronomical time and mains frequency on the LED large-screen in control room in real time, the method makes the LED large-screen in control room can show astronomical time and mains frequency in real time, ensure that regulation and control personnel fill in operational order and send the time or the accuracy of the signal time that notes abnormalities, improve regulation and control personnel to the promptness of accident and abnormality processing and accuracy.
In order to solve prior art Problems existing, the technical solution used in the present invention is:
LED large-screen shows the method for astronomical time and mains frequency in real time, comprises the following steps:
1. astronomical clock NTP delivery outlet IP address is set, astronomical clock NTP delivery outlet is connected with OPEN3000 system major network switch, the satellite time received is sent to power network schedule automation main website OPEN3000 system by astronomical clock, the major network switch of OPEN3000 system by NTP mode receive astronomical clock pair time message and successfully pair time;
2. OPEN3000 major network switch network interface is connected with LED large-screen controller, when the mode when astronomical time that collects is adopted network pair by OPEN3000 system major network switch and LED large-screen controller pair, being configured to the major network switch of OPEN3000 system by this locality of LED large-screen controller connection network interface card is the same network segment, choose automatically and network time synchronization server ip is configured to be preserve after the same network segment with the major network switch of OPEN3000 system in network time is arranged, can with OPEN3000 system pair time;
3. the real-time grid frequency collected is sent to LED large-screen controller in the mode of FTP by OPEN3000 system, and FTP sends being spaced apart 1 second of file and automatically covers the frequency file of first 1 second, to reach the object without backlog document;
4. LED large-screen controller receives ftp file, and astronomical time and mains frequency are arranged respectively to module, and astronomical time module installation is display the machine time and astronomical time; Mains frequency module installation, for receiving mains frequency TXT file mode, can show the mains frequency that second, level refreshed.
Step 1. in astronomical clock NTP delivery outlet IP is configured to 192.169.30.185, step 2. in this locality of LED large-screen controller is connected network interface card configuration of IP 192.169.30.186, choose in network time is arranged automatically and network time synchronization preserving after server ip is configured to 192.169.30.185.
The advantage that the present invention has and effect are:
When the present invention utilizes the OPEN3000 system in automation main website machine room and existing LED large-screen controller pair, and by OPEN3000 system acquisition to mains frequency be presented on LED large-screen in the lump, solve the demand of regulation and control personnel to astronomical time and mains frequency, adopt astronomical time, realize automatic correcting time and pair time precision reach Millisecond; Save the funds buying free-standing frequency meter; Effective astronomical time and mains frequency and scheduling hall LED large-screen are combined together, not only neat appearance, also substantially increases the operating efficiency of regulation and control personnel.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is control method flow chart of the present invention.
