NTP standard time service server, clock serve

  ◆ time service interface: 10/100m adaptive Ethernet interface with 4 independent IP addresses, ◆ vacuum fluorescent display (VFD) display window, displaying clock source information, signal strength, time and date, and data validity;
◆ time source: the 4G, GPS and Beidou time sources can be switched to each other to ensure the time accuracy when the road is blocked;
◆ timing accuracy: 4G time source timing accuracy is 5ms, gps/ Beidou timing accuracy is 10 mu; s
◆ Beidou receiving channel 6, receiving sensitivity: -157
6dbw; Cold start time: 15 seconds, hot start time: 1
5 seconds
◆ 4G operating frequency: 800MHz, no SIM card, receiving sensitivity -166dbw; Cold start time: 10s, hot start time: 1s
◆ GPs working frequency: 1575
42MHz; The receiving sensitivity is -163dbw, the cold start time is 15 seconds, and the hot start time is 2 seconds
◆ built in constant temperature crystal oscillator for punctuality, which can maintain accurate system time for a long time without satellite signal;
◆ network time synchronization accuracy: NTP on tcp/ip network: 1-10ms
◆ the server IP can be manually modified and set, which is easy to operate and easy for non professionals to maintain and manage;
