1. Hospital monitoring required 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 to several critical emergency ward and the operating room and other places. Some infectious diseases, especially during the period of "SARS", brought great inconvenience to our life, especially to work in a line of doctors and nurses, because they are healthy people closest to the source, is also need to take the initiative to close to the source of the crowd, thus giving their caused great threat to health of body and mind, only their healthy, we can obtain the health, in order to ensure their health, we will make them to create a work environment away from the source!

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.

2. The design ideas

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 information age, computer network equipment has been widely used in hospital all night, so, for the design of 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, 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, save investment.

Third, equipment upgrading, does not destroy the original structure.

Fourth, equipment maintenance, maintenance, simple operation, friendly user interface, but spend more manpower and material resources.

Fifth, based on the existing network foundation, cost savings, plug the look, easy expansion.

3. Description

This network of hospital monitoring system has the following two kinds: one is based on the DVR hard disk video recorder way; The second is based on video server

This system is divided into (front) and point to point control center (backend) two parts, the front end through video coaxial cable connection. The front with video cameras and yuntai main components; Back-end control center consists of DVR and switches and other parts, main is to control the front-end video capture and video storage. Each department authorized by control software and can control the rotation of the front camera.

This monitoring system is on the front end to add a video server and back-end control center change DVR hard disk video recorder to a control server, used to control the direction of the front camera rotation and video storage, its connection is via a transmission of five kinds of cable to the network switches to connect to the server in the control center, only need to use camera and network video server, video line connection and cable will be connected to the LAN network video server.

Monitoring system is divided into three parts:

1. The control center

In setting the monitoring center, information center, or room, choose high configuration PC as monitoring host, installation of monitoring software of the DVR system, management personnel through DVR monitoring software, to conduct a comprehensive monitoring of management;

Hospital, department leadership in the monitoring center, or in their offices, through the computer network, computer monitor each scene, to facilitate supervision and management.

2. Monitoring site

Including the operating room, disposal of room and ward to set up monitoring sites, operating rooms, disposal rooms and ward number and location of the camera can be according to actual situation.

Within each unit connected to a network video server and a video camera, network video server by RJ45 interface, local area network (LAN) access network switches, and the monitoring center monitoring host of the network video monitoring system.

3. The display terminal

In addition to the network video monitoring system, can be in local area network (LAN) in the number of PC computer, install the client software or Internet explorer, as a display terminal, apply to:

1. The hospital medical staff, regulation of each ward patients;

2. Learning view operation;

For operating room, due to the indoor area restrictions and operation instruction, can't hold a lot of people, especially for narrow surgical site, at this point by the surgeon wearing a miniature camera system, near to the operating room the multi-angle camera on metope, will be able to details in the operation, and can according to the need of processing technology, operation for the training of medical students and staff skills improve all is very beneficial.

3. Hospital consultation;

Located in different locations of the doctor, with mutual consultation

4, system function

1. The multi-channel monitoring

This system can simultaneously to monitor many ways on the picture video at the same time, the user can select the point to point video channel. The monitoring center can select each point to real-time monitoring at the same time; Multi-channel can connect large screen color TV sets to monitor; The leadership of the school, department shall 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, this system can make the multi-user access to the same network video server at the same time.

2. Critically ill patients visit

For critically ill patients, or patients in the care unit, due to prevent bacteria infection, objectively medical personnel outside the personnel are not permitted to 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 footage

This system in MPEG4 format compression the video signal and can be stored for a long time. Corresponding alarm prompt before the hard disk is full, can also loop video, or burn a CD store.

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. The 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. Yuntai and camera control

Camera adopts fixed focal length, the direction of the fixed way, in the light change places should choose 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.

6. Multiple 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.
