Single face clock autonomous and controllable

Single face clock autonomous and controllableMainly for the computer system and call system of the entire hospitalBAThe system, operating room control, and other weak electronic systems provide standard time sources, enabling key departments such as medical orders, attendance, medical insurance, financial centers, and warehouses to obtain accurate and unified standard time; To provide timely and accurate nursing time reference for special care patients and critically ill observation patients for the staff of the nursing station, intelligent single face clocks are no longer needed for the anesthesia room, operating room, oxygen supply and respiratory system to manually check the clock for timing, thus achieving unified time throughout the hospital and providing accurate time guarantee for digital management of the hospital.

Produced by Shanghai Ruicheng Electric Co., LtdSingle face clock autonomous and controllableDesigned in accordance with relevant national and industry norms and standards, and strictly following the various special requirements of hospital intelligent building engineering for clock systems, it is a technologically advanced, highly intelligent, and functionally complete clock systemIt can achieve the unification of time standards throughout the hospital, so that staff and patients can grasp accurate and unified time information at any time, enabling various business departments and functional departments to work in an orderly and coordinated manner, providing a standard time basis for organic coordination and close cooperation between functional departments, and ensuring adaptation to the high-speed operation needs of various related businesses in the hospital's intelligent buildings.

4Single face clock--Characteristics of digital sub clocks

High synchronization accuracy - using intelligent time compensation technology

Long visible distance and good angle - using high brightnessLEDAnd anti glare panel

Low power consumption - using dynamic scanning technology and can achieve timed switching

Constant current drive, bidding farewell to traditional voltage drive,Significantly extendedLEDlifespan

Multiple timing methods -RS422/485TheNTP/SNTPNetwork, wirelesswifiTheCDMAThe4G

Intelligent management - can communicate with the upper computer and monitor the running status in real time

The shell is made of special mold processed sheet metal, anti-static, anti electromagnetic interference, and coated with metal matte paint on the surface. The display clock face is treated with anti glare, and there is no reflection when placed under a fluorescent lamp
