NTP time synchronization server Business claims

Open Category:

Edit summary NTP time synchronization server is sometimes carried out research and development of high-tech products school for computers, automation devices, NTP time synchronization server acquired from the GPS satellite standard time signals, those signals transmitted through a variety of interfaces to the automation system takes time (Computer, protection device, fault recorder, event sequence recording device, security automation devices, remote RTU), so that you can achieve the entire system time synchronization - Shanghai Jun Wei Albert company to provide you with comprehensive solutions . NTP server GPS time synchronization signal as a time source and optional Compass, B code, CDMA, atomic clock time source. NTP time synchronization server product fully modular design, not only the card is fully compatible, but also provides a wealth of resources and open signal interface special interface design platform, with excellent compatibility. IRIG-B signal (TTL, 422, AC, TTL, 24V / 110V / 220V active, light) can be provided with multiple NTP / SNTP signals, PTP signal, pulse signal (1PPS / M / H, Light, DCF77 signal, time message (RS232, RS422 / 485, light), can meet the different time interface requirements, widely used in electric power, finance, communication, traffic, broadcasting, security, petrochemical, metallurgy, Defense, medical, education, government agencies, IT and other fields. Time synchronization server using surface mount technology production equipment, high-speed chip control, with high accuracy, good stability, strong function, no accumulation of errors, without geographical climate and other environmental conditions, cost-effective, easy to operate, maintenance-free Features, suitable for unattended.

Support single-star timing mode for the poor reception of the situation, there are roof and window antenna to choose from. 4. Using dual-core processor, high precision, fast synchronization. 5. The GPS receiving antenna focuses on lightning protection design, stability design, anti-jamming design, high reliability of signal reception, and is not limited by the local conditions and environment of power plant / substation. 6. The device has self-resetting capability, which can automatically resume normal operation when the device program error is caused by the interference. 7. The device has power interruption, GPS out of step alarm multi-channel alarm (relay dry contact) signal output, on-line monitoring device operation. 8. There are a variety of work status instructions, easy to run daily visits on duty. 9. The device adopts the modularized plug-and-play structure design. It supports hot-plugging, flexible configuration and easy maintenance. It also provides convenience for future power plant / substation transformation and expansion to increase or change the timing signal interface. 10. The device provides a programmable TTL pulse signal (1PPS / 1PPM / 1PPH) for the clock accuracy index test. 11. Device can be displayed through the digital tube to track the number of satellites, on-line display device star status. Time synchronization server device detailed parameters: 1. Time source: GPS, Beidou, CDMA, IRIG-B, crystal oscillator OCXO, atomic clock Power: 220V / 110V AC, DC adaptive, dual power supply GPS receiver frequency: 1575.42MHz, receiver sensitivity: capture -160dBW, tracking -163dBW. Capture time: 5min for cold start, 1min for warm start. 4. Mean time between failures (MTBF) 150000 hours, under normal use conditions without maintenance. 5. Timing accuracy: pulse, B code 0.1S, serial 10S, NTP / SNTP 1- Dimensions: 1U / 2U, 19 "standard case, easy installation 7. Standard antenna length 30m, optional 50,60,80,100,120,200 meter time synchronization server product quality and service: 1. As Time Synchronization professional server equipment suppliers, the products are nearly ten thousand scene stable operation, quality guaranteed. 2. Our time synchronization server, three years free warranty and lifetime maintenance software to take a later free upgrades for life. 3. customers enjoy full free Worry service, on-site online operation equipment failure, maintenance personnel arrived at the scene within 24 hours (special circumstances within 12 hours), the maintenance time is generally not more than 30 minutes.

Domestic manufacturers have Beidou time frequency technology limited company, Beidou time frequency technology limited company research and development time frequency products already covered the rack type, the table type, the portable type, the hand-held type, the card type and so on many kinds of product types. GPS / Beidou time code generator (time code), Beidou / GPS network time server, Beidou / GPS timing card (time card / time code card), PCI / Compact PCI / Compact PCI-E time code card, IRIG-B code decoder card (B code / time code card), high stability network security NTP time server, IEEE1588 (PTP) precision master clock / slave clock, Compass GPS clock synchronization, Beidou GPS taming the rubidium atomic clock (GPS rubidium atomic frequency standard), Beidou GPS tame constant temperature crystal (GPS high stability quartz frequency standard), frequency distribution amplifier, frequency seamless switch, pulse signal distribution amplifier, IRIG-B time code distribution amplifier, High-precision time interval counter, high-precision frequency meter, such as the phase meter. Beidou Time Frequency Technology Co., Ltd. service users include the General Staff Headquarters, the General Assembly, the Navy, the Air Force and other national defense key units, and China Aerospace Science and Industry Group, China Flight Test Research Institute, CLP Group, The State Grid, China Mobile, China Unicom, China Central Television and other national key ministries and commissions. Applications, and aerospace, defense and military, public security systems, power systems, research institutes, measurement and calibration, radio and television, telecommunications, finance, transportation and so on. Product quality and reliable, leading technical indicators, won praise users.

Asiatic Lion

Asiatic Lion is the tallest of the Bala dynasty and the largest animal after the African lion. This animal is found in the Gir sanctuary of Saurashtra only in the whole of Gujarat. Asiatic lion is one of the 5 big cat oats found in India. The other four species include the Bangalore Tiger, the Indian diaper, the snow leopard, and the clouded leopard etc. In the past, when it was seen from Arabian to Sumatra, three species of Bengal were lions of Bengal, lions of Arabia and lions of Iran, and today only a few parts of India are found only today. It is small in size and color is blurred from the lion found in Africa. But aggression is the same in both of these species. Asiatic Lion marks the urine by urinating on the lioness tree. 1 Behavior 2 Lives - Human conflict between the people 3 Population 4 References 5 External links Curiosity These animals are usually found in the winter season, around open areas around the forest in the open areas and during the summer season water bodies...
