Localization of Embedded Electronic Clocks

1、Localization of Embedded Electronic Clocks

Sub clocks, as terminal time display devices for embedded electronic clocks, are the basic equipment in the unified system solutions for standard time in various industries. The high-precision sub clock series products produced by Shanghai Ruicheng Electric Co., Ltd. can receive standard time synchronization signals from the master clock or other standard time sources and automatically perform time correction; In the event of a communication interruption with the master clock, it enters the self guarding operation state and can automatically calibrate after the master clock signal is restored. The clock can be passed throughNTPNetwork, wirelessWIFITheCDMAThe4GandRS485Multiple communication methods such as serial port can obtain standard time, and the sub clock can strictly compare, analyze, and judge the received time synchronization signal, thereby eliminating the interference of abnormal time information.

The Rui Cheng series of sub clocks has multiple styles, high time accuracy, and flexible interfaces, which can meet various needs of sub clocks in various industries. The product is widely used in public places in different fields such as hospitals, pharmaceuticals, airports, stations, subways, schools, civil air defense, sports venues, radio and television, office buildings, etc.

4Classification of Embedded Electronic Clocks

Ethernet wired access to the central master clock orNTPThe time server obtains standard time, and this type of sub clock is referred to as network sub clock orNTPZi Zhong.

WIFIWireless access to the central master clock orNTPThe time server obtains standard time, which is abbreviated as this type of sub clockWIFIZi Zhong.

CDMAWireless reception of signals from China Telecom base stations to obtain standard time, referred to as this type of sub clockCDMAZi Zhong.

5Installation of Embedded Electronic Clock

All single face clocks can be installed by hanging or hoisting, while double-sided clocks can only be installed by hanging or hoistingInstallation method for hoisting. Our company also has embedded sub clocks, specifically designed for embedded installation.

5.1 Hanging method

The back of the single face clock is pre installed with stamped wall mounting holes. The power and signal lines of the single-sided digital sub clock are connected through the top opening by default, or can be customized to be connected through the back opening. The power and signal lines of the single-sided pointer clock are connected through the back opening.

5.2 Lifting method

Both single-sided and double-sided sub clocks can be installed by lifting. Randomly equipped with suspension rods, default size of suspension rods: length300mm, diameter20mmThe length of the suspension rod can be customized.
