As an important timing and punctuality equipment, atomic clocks have many limitations in their use. Most of existing clocks are monitored by local computer terminals, but for user parameter adjustment and fault diagnosis are both professional and difficult to complete. Moreover, for maintenance personnel, it's hard to grasp the situation of problematic clocks. It also increases the difficulty of fault location, consumes more time and effort.This article puts forward an idea of realizing parameter control digitization through improved control system, remote monitoring through the Internet of Things, and intelligent diagnosis of fault diagnosis through Artificial Neural Network(ANN). Taking hydrogen maser as an example, it can only be manually adjusted. So we digitized the manual circuit and wrote program on it, letting hydrogen maser intelligently judges the current running state and automatically adjusts its internal parameters. For problems which are difficult to adjust by itself, the pre-judgment can also be carried out to a certain extent, which is convenient for the technician to fix. In addition, hydrogen maser has an embedded web server, uses the Internet of Tings(IoT) to deliver parameters, state analysis results, historical data in real time, then performs device identification and data sorting. User can access it by any browser-equipped terminal, instantly view the data and command hydrogen maser, thereby realizing the real-time, unlimited geographical area, and intelligent analysis of remote monitoring atomic clock system.
