Application software function

(a), the hospital computer equipment table of various functional departments

The whole system consists of a server and several workstations, and each subsystem works cooperatively on the network, providing flexible business inquiry and strict authority control between departments. Each subsystem provides a general query function, and each subsystem can only use the functions it has the right to call under this function. The data shared between networks is real-time, which can avoid data inconsistency between departments.

(2) Functional view of hospital management subsystem

Hospital management subsystem (HIS) usually includes two parts: outpatient department and inpatient department. The main line of management is drugs and the amount of money collected.

1, view description:

The above is the function view of various functional departments in the hospital. The departments in the box are departments equipped with computers; Departments in parallel lines are related departments in hospitals. What is passed between departments is data information. Because the personnel section and the general affairs section are relatively independent, they are not included.

Hardware platform system design

Hardware is the basis of system realization. In the design scheme, we consider the various requirements and characteristics of the system implementation and the actual situation of the hospital. When selecting hardware, we must meet the system requirements, give consideration to the system performance, and take the highest cost performance as the principle to make the system reach the optimal and most economical scheme.

1. server (server)

The main server is the heart of the system, and all workstations in the system must exchange information with it, so it must be fast, stable and reliable in quality.

2. Workstation

The choice of workstation is based on ensuring the high-speed operation and high reliability of the network. At the same time, considering the actual situation of the hospital, it can not only meet the requirements of the system, but also save limited funds for the hospital itself.

3. Printer

We mainly choose printers with fast printing speed, durability and low running cost. The products of world-famous printer manufacturers fully meet their requirements.

4. Distribution power supply (UPS)

When the power supply is interrupted, if the network is running, it may lead to data loss and equipment damage, thus causing irreparable losses. Therefore, it is necessary to ensure the uninterrupted operation of the machine, but it can only be provided for a short time and give an alarm.

Power network design

Hospital management system is a comprehensive system. Therefore, Dalian Huiyuan Electronic System Engineering Co., Ltd. not only takes into account the characteristics of wide management, many departments and timely information exchange requirements, but also takes into account the actual situation of the hospital. The network adopts international standard star network topology structure, which has the characteristics of flexible expansion, convenient maintenance, stable operation, good interconnection and reasonable cost performance, and is the best and most economical scheme adopted by computer network system.

1. Integrated wiring

Cable is the lifeline of computer network and the artery for transmitting information. If the line is damaged due to quality problems, the network will be completely paralyzed and stop working. Therefore, we adopted the integrated wiring scheme of building automation in the design, strictly in accordance with the technical requirements of integrated wiring, so as to improve the quality and stability of the line. At the same time, it can be used for language transmission, which is convenient for users to choose freely According to the site situation, the cable can be connected to the RJ-45 socket on the wall or directly connected to the workstation with RJ-45 plug, which is convenient for maintenance and expansion.

2. Network equipment

Network devices are mainly switches and hubs, which are intermediate devices connecting the main server and the workstation. Switch is the core equipment in the network, which provides fast connection between server and workstation. There is also a hardware device in the network, that is, a network adapter, also called a network card, which is used to connect various workstations with cables. Because the network card is the main equipment connecting each workstation with the network, in order to make the workstation work stably, it is necessary to ensure a network card with good compatibility and high reliability.

3. Network management

In order to make full use of network resources and facilitate management and maintenance, we adopted the above network scheme. In planning, we make workstations not interdependent, but interconnected. That is, the running state of one workstation does not affect the normal operation of other workstations, which improves the reliability of the network.

Database system and system management platform

1, database system

Hospital management information system has a huge amount of data and strong real-time performance. When choosing a database system, it is necessary to choose an efficient and stable large-scale database system.

2. Network operating system

Network operating system is a layer of software platform based on network hardware devices. Without the network operating system, it is impossible to form a reasonable computer network system. The network operating system is an important part of the network because it is stable and closely cooperates with the database system.
