Description

Intelligent operation and maintenance management platform for hospital environmental facilities

technical field

The invention belongs to the technical field of hospital facility management, and particularly relates to an intelligent operation and maintenance management platform for hospital environmental facilities.

Background technique

In recent years, with the rapid development of medical technology and the high requirements of patients for the medical environment, the construction of clean equipment projects is highly specialized, has high comprehensive requirements, and is difficult to design, construct, operate and maintain. The future development trends are mainly in terms of technology, green energy saving, In terms of operation and maintenance, we can ensure long-term development in the competition of the market environment. The clean equipment project requires an engineering team with experience in after-sales maintenance to strictly ensure the quality of the purification project. There are many purification companies in the market. There are countless purification projects contracted and constructed every year. From the start of construction to the completion of the project, each contractor is basically responsible for a maintenance period of about 2 years. After the maintenance period, the hospital will not sign it. The contract continues to let its maintenance or training personnel maintain it by themselves. During this process and later, there is often a shortage of personnel in the project contracting unit. Several projects interoperate with maintenance personnel. When a cleaning equipment failure occurs, they cannot go to the site to troubleshoot in time. It is still in the artificial age, which will bring a greater risk to patients' lives. The actual operation status of the equipment on site cannot be understood in time, the information is lagging behind, and flexible maintenance is impossible. Other units do not pay attention to operation and maintenance. This phenomenon is very dangerous. of. To realize the comprehensive operation and maintenance of the automation system is the top priority of the operation and maintenance of the clean equipment project at present.

At present, the hospital has many environmental facilities and systems, complex composition, high energy consumption, lagging information construction, prominent information islands, difficult operation and maintenance in the later stage, and inadequate supervision. With the increasing energy consumption, environment, stability, etc., how to meet the scientific, humanized and personalized needs of the medical field? This requires enterprises with professional talents to have a forward-looking understanding of the development of clean engineering, rich design, construction experience, and effective monitoring of facilities and personnel during operation. A place where diagnosis and treatment work can be done comfortably, providing a safer and more comfortable rehabilitation environment for patients.

At present, most of the clean engineering management informatization in China is still in the stage of small-scale independent control, which is characterized by no network or small-scale local area network control;

In the field of clean equipment engineering, the vast majority of domestic control systems only focus on control, but neglect fault detection. As we all know, once there is a problem with the equipment used in the field, it is difficult to locate and eliminate the fault. Hospitals are the basic facilities to ensure the safety of people's lives. Due to the particularity of such environments, extremely high reliability, stability and uninterrupted use are required, as well as the requirements that faults must be eliminated as soon as possible.

For the existing hospital clean equipment engineering control system, we draw the following conclusions:

1) The air-conditioning system of the hospital mostly adopts the microprocessor single-chip control system, the panel is a flat touch type, and the parameters are displayed through the digital tube, and the display screen is single;

2) General basic functions can be realized, but secondary expansion cannot be performed;

3) The parameter control is a single control, the anti-interference ability and communication function are poor, and it cannot handle a large amount of data and high-speed transmission of data.

4) The control items and functions are scattered, and the air-conditioning system, intercom, acquisition, etc. have different control cores, and the management is scattered, which is more complicated for hospital staff to grasp. The above problems are not suitable for the current development needs of information technology in the industry.

5) In the previous system, the communication adopts the method of field bus communication, which has low efficiency, slow speed and complicated protocol, and is no longer suitable for the current large-scale integrated and networked information acquisition and control system.

Camera management is used for functions such as adding, deleting, editing, and viewing cameras. Currently, the 7.0 platform only supports Hikvision's EZVIZ cloud cameras.

Institutional management:

Organizations can be used to organize and divide projects. They can be administrative levels, regions, or user-defined. When creating a project, you can choose the corresponding top-level organization or sub-organization, and you can select multiple organizations or cross-organizations.

Explanation of platform institution management rules: Institutions are divided into top-level institutions (institutions without a superior institution) and sub-institutions.

Job management:

Positions are used to constrain user permissions. A position can have multiple users, and users in the same position have the same permissions.

Positions can be divided into the following three types: multi-top organization management positions: can manage all top-level organizations and sub-organizations, and can assign all functional permissions of the platform; single-top organization management positions: can only manage one top-level organization and its sub-organizations , can assign all functional permissions of the platform; ordinary users: In addition to assigning each functional permission, you can also assign specific projects, screens, devices, etc.

Note: Multi-organization management positions and single-organization management positions have the authority of the management organization, so there is no need to assign equipment authority and screen authority.
