WiFi digital clock with low power consumption

wifiThe digital clock is mainly used 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 references for special care patients and critically ill observation patients for the staff of the nursing station, intelligent systems have been developed for anesthesia rooms, operating rooms, oxygen supply and respiratory systems, etcwifiAfter the digital clock, there is no longer a need for manual clock counting, thus achieving unified time throughout the hospital and providing accurate time assurance for digital management of the hospital.

Produced by Shanghai Ruicheng Electric Co., LtdwifiThe low-power digital clock complies with relevant national and industry norms and standards, and is designed strictly in accordance with various special requirements of hospital intelligent building engineering for clock systems. It is a technologically advanced, highly intelligent, and functionally efficient 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.
