Frist,hospital monitoring, necessary performance
Network monitoring system has a broad prospect of application in hospitals, clinics, hospital building security monitoring, ward, care of patients with 24 hour care, surgery to learn of the surgery, the doctor's consultation together, is the place, but the most direct application of point is critical important items to store room and emergency ward, operating room and other places.
It is based on the above reason, the urgent need to the operating room, hospital ward as primary monitoring sites, for each operation and each ward patients as much as possible the implementation of the real-time monitoring all the way, is conducive to the standardization of the hospital management, improve the diagnosis and treatment and nursing of the patients with level, at the same time, to save operation video, helps to solve medical disputes, distinguish responsibility.
Second, the design thought
Any design scheme of the most fundamental premise is that the needs of users, and advanced, mature technology, reliable, flexible application, the trend of the development of the technology and good performance/price ratio is the most basic foundation design scheme. Should be in do not break the advanced nature, maturity, reliability, scalability, on the basis of taking into full consideration the needs of users, to take care of the long-term interests, utmost ground protects user investment.
Network monitoring system is increasingly attracting widespread attention and application of its class and type of product also more and more. According to the requirement of the hospital, in line with high standard, high quality, improve product performance and low cost, on the design fully embody the digital trend, at the same time, considering the user for ease of use, maintenance, maintenance.
In the process of informatization, the computer network equipment has been widely applied to hospital management and business activities, therefore, to the design of the video monitoring scheme, you must first select seamless access to existing computer network monitoring equipment. Based on the TCP/IP protocol of advanced digital video monitoring equipment, is the preferred products.
Second, since the construction of the monitoring system, can not be achieved overnight, but to stage, with the improvement of medical environment, medical devices and introduce, and continued to expand. Therefore, to choose the monitor equipment with high extensibility. Need to add capacity in the future, continue to use the original equipment, only need to add new equipment. Instead of the original equipment scrapped, to purchase equipment.
Three, program description
This system according to the monitoring of hospital were divided into two level monitoring system: the front-end acquisition signal monitoring points and monitoring center.
This monitoring system can use the existing hospital LAN environment construction, does not need wiring separately, save your wiring manpower and time, just with a camera and network video server, video line connection and network cable will be connected to the LAN network video server.
Monitoring system is divided into three parts:
1. The monitoring center
In setting the monitoring center, information center, or room, choose high performance PC as monitoring host, network video monitoring software, system software installation management through software, to conduct a comprehensive monitoring of management;
School, department, such as hospital leadership in the monitoring center, or in their offices, use of the computer through a computer network within the office, can monitor to the scene of the scene, to facilitate supervision and management.
2. Monitoring site
Including the operating room, treatment rooms, special goods storage room and ward to set up monitoring sites.
The operating room, disposal of room and ward number and location of the camera can be according to actual situation. Generally in each room at the top of the central location to install a spherical camera intelligent high-speed ball (small size), using the installation type suction a top. Through the monitoring center system of network monitoring software, control connected to the camera haeundae about rotary, the pitch, the camera is not restricted to level 360 degrees, vertical rotate 90 degrees, 18 times three variable lens images can be arbitrary zoom in, ward patients activity image can be clearly displayed in the center of the monitor.
Adjacent 4 cameras video signal, access to a network video server, network video server according to the pattern of the ward, the operating room, placed in appropriate places near construction simpler, also saves floor space. Through the RJ45 interface, network video server access hospital local area network (LAN), the existing monitoring host connection with the monitoring center.
3. The display terminal
Video monitoring system of the trunk, can be in local area network (LAN) in the number of PC computer, install the client software, as a display terminal, suitable for:
1. The inpatient medical personnel, supervision each ward patients;
2. Learning view operation;
For the operating room, due to the indoor area restriction and surgical procedures such as conditions of requirements, impossible to accommodate more people, especially the operation area is narrow small, must pass around the operating room at this time the multi-angle camera on metope, can reveal all the details to the operating room, and can undertake processing technology, according to the need for surgery for the training of medical students and staff skills improve all is very beneficial.
4. The hospital consultation;
The whole monitoring system as a subsystem of hospital management system, video monitoring subsystem, can smoothly blended in among them;
Network video server, using the dedicated video codec chip, embedded real-time operating system, from the easy to crash in the Windows system, completely out of the monitor of the computer plug-in machine model, adopting the distributed monitoring design, greatly reduces the coupling degree of system, reduce the failure rate, the stability of the system get the fundamental guarantee.
Four, system function
1, multi-channel monitoring
This system can simultaneously for 12 or more because of video monitoring at the same time, the user can choose any area of the video channel.
The monitoring center can select 12 monitory point in this area real-time monitoring at the same time; More than 12 road can use a loop to display or use the computer to monitor hospital, department, such as the leadership of the hospital, have the right to monitor all sites within the entire network video scene
Can use the display terminal users, watch the permissions within the video scene, can with other users to watch at the same time, because this system allows multiple users to access the same at the same time the network video server.
2, critically ill patients visit
For critically ill patients, or patients in the care unit, due to prevent bacterial infections, objectively medical personnel outside the staff don't have permission to access (in fact, there are very few families enter), to the patients' family members to visit relatives on the display terminal illness, the patient's mental outlook can be clear at a glance, so as to alleviate the anxiety of family members, and also improve the level of the hospital care.
3, video video
USES the hard disk record multi-channel real-time monitoring signals, from ordinary video recording of some inconvenience. Because the system will video signals in h. 264 format compression, so greatly reduced amount of data, can be stored for a long time. Hard disk storage full before have corresponding operating hints and loop video.
Monitoring center users can through the central monitoring software, video scene video region set, the user can choose prestore video channel, video preset time
4, video retrieval and playback
According to the user's query request (for example, when a certain address) query to record the data on the hard disk, and show a replay, for later investigation. Playback can be fast forward, fast, slow, slow down, step control, such as single frame image can amplify the whole figure, local amplification.
Video retrieval and playback, give priority to with the monitoring center, can to some important scenes, for video retrieval and playback.
5, multilevel user password management
The user ratings of management, different levels users have different operating authority, improve the system security. Can be set during system installation, also can change Settings any time after the system is running.
6, haeundae and control lens
Under normal circumstances, the camera USES the fixed focal length, the direction of the fixed way, in the light change big place should use automatic aperture lens and equipped with protective cover, a wide range of monitoring area appropriate chooses with rotational yuntai and zoom lens of the camera.
The monitoring center through the central monitoring software, can control the remote cameras and yuntai rotation
