1. System overview:

Anhui Jingzhun HR series digital slave clock system mainly provides accurate and standard time for the hospital. The system uses GPS and Beidou satellite navigation and positioning system time standard signal as the standard time source to calibrate the clock signal source of master clock, provides accurate clock signal to the clock of medical places and computers in LAN, and monitors the working state of all clocks, so as to make the network work better Beijing time, which is consistent with the satellite time signal, can be displayed at each location where the slave clock is installed.

(1) Synchronous proofreading

As the basic master clock equipment, the central master clock should be able to automatically receive the standard time signal from GPS, calibrate the time accuracy of the central master clock, generate accurate standard time signal, and transmit it to each sub clock through the transmission channel;

(2) Time display

The central master clock shall display the time in the format of year, month, day, week and hour: minute: second. The time of the pointer type slave clock is displayed in minutes, and the digital display slave clock is displayed in minutes: seconds; the calendar digital display slave clock displays the year, month, day, week, hour, minute and second.

(3) Network time service

A NTP time server with redundant main and standby power supply and multi-channel NTP 10 / 100 adaptive Ethernet output interface is provided

(4) System monitoring function

The system shall monitor the clock equipment separately. With self diagnosis function, it can carry out general management, fault management and safety management.

2. Development trend

Clock system, often called master clock in the past, consists of a master clock with several slave clocks, so that the time of all the slave clocks is consistent with that of the master clock. In the past, the master clock usually sends driving pulse to drive the motor of slave clock directly, so as to realize the time synchronization between master clock and slave clock. With the development of communication technology, the time synchronization between the master clock and the slave clock is mostly realized by the communication mode. Because of the use of communication mode, the system can not only synchronize the time of the slave clock, but also synchronize other devices in the system that need time synchronization, so as to expand the function of the slave clock and master clock, so it is more appropriate to call the clock system.

It is suggested that the temperature and humidity of the operation room should be clear in 2006, and the operation time should be clearly displayed in the operation room.

JCI is a subsidiary body of Joint Commission on Accreditation of healthcare organizations (JCAHO) for accreditation of medical institutions outside the United States.

JCI is composed of international experts in medicine, nursing, administration and public policy. They come from Western Europe, the Middle East, Latin America and Central America, Asia Pacific region, North America, central and Eastern Europe and Africa.

At present, JCI has provided guidance and accreditation to public and private medical and health institutions and government departments in more than 40 countries in the world, and 78 medical institutions in 13 countries (including China) have passed the international JCI certification. JCI certification clearly stipulates that the hospital information system must have a clock system, which is a hard condition to pass the certification.

According to “11.11.4” in the industrial standard of the people’s Republic of China “code for electrical design of medical buildings – jgj312-2013”, display clock should be installed in registration, outpatient service, charging, dispensing medicine, blood drawing, examination, reporting, waiting area, operating room, various departments, channels, ward, etc. For the first time, the function of clock system and the design and installation position are clearly proposed in the official authoritative industry standard.

In the reform of medical informatization and automation, especially since the application and popularization of his system, the importance of clock synchronization among data servers becomes more prominent (the clock synchronization between servers leads to data packet loss). It can be said that the role of the clock system in the hospital intelligence has evolved from a simple slave clock to a hospital intelligent clock synchronization benchmark, which is an essential and important part of the hospital intelligent construction.

3. The system adopts network time synchronization technology

Network time synchronization technology is a low-power network time protocol based on NTP / SNTP standard. According to this protocol, the technology is a long-distance, low-power LAN communication technology. In other words, when the master clock (time calibrator) system transmits the synchronous signal, many slave clocks (displays) in the area receive the signal synchronously. Through network communication and processing, all the slave clocks display the same time, which fundamentally solves the current situation that the time in the office building is not synchronized. Each on-line equipment directly receives the time synchronization system signal of the central master clock in the computer room, and can automatically eliminate the accumulated error. All network digital slave clocks, management computers, clock network management monitoring system, and other weak current systems obtain standard time through the network.

The clock management system is connected with the slave clock through the network to realize the security management, alarm management, log management, fault management, configuration management, state management and remote management of the clock system. The central master clock unifies the network digital slave clock time through the network switch. The network digital slave clock can reflect the fault (such as code segment fault) upward by connecting with the network, and reflect to the clock management system through the network switch, and the clock management system automatically generates logs. All the computer systems in LAN can receive the standard time of master clock and realize the clock synchronization of the whole computer network.

4. The network time synchronization display system consists of:

The scheme of Anhui Jingzhun clock system can realize the hospital time synchronization by the most concise and economical method. For example, the BA system, call system, operating room control system, computer network and other systems that need standard time reference have reserved clock receiving function, and all of them are in a local area network, then the time can be given to these systems through the network output interface box The advantage of the scheme is that it can support the devices of different operating systems to receive the same time standard without adding devices.

Each online device obtains time source from the central master clock. The central master clock has built-in high-stability OCXO. If the time source is abnormal or interrupted, the main and standby master clocks automatically switch to rely on OCXO high-precision self travel time, which can ensure the time accuracy obtained by NTP without interruption of external time service. When the time source recovers, the system automatically switches to the current time source as a standard reference. NTP time server can display date, day, week, hour, minute and second information through LCD.

Each slave clock has an independent IP address. The IP address can be changed through software settings. The IP address of the time service server can be preset (or modified after delivery) by the slave clock, The NTP server will send a time service request to the server every 1 minute or 5 minutes (the interval time can be set freely). After receiving the time service application, the NTP server will send a response time packet. The slave clock will receive the response time packet and automatically calculate the network delay error to complete one time service.

Other system management servers and all computers that need to receive standard time can point the server address to NTP server IP through the time service setting window provided by the operating system to complete the automatic time service process. The time interval of computer is updated once a week by default, and the time interval can be adjusted by modifying the registry.

The standard time synchronous display clock system consists of satellite signal receiving module, CPU single chip processor, NTP network processing module and standard time display module.
