In order to make the electric operating tables in each medical institution have good management and maintenance, this paper proposes a system that can monitor and diagnose the running conditions of operating table visually and remotely. The system use advanced sensor technology to collect all kinds of parameters of operating table, and send the data to Data Center through the wireless transmission way. In order to realize the visual diagnosis, this paper provides several kinds of models to display the real state of operating table, including mechanical models, hydraulic models, electrical structure models, and the corresponding internal small unit structure models. Then the staff can monitor and diagnose the operating table according to the various models. Furthermore, this paper purposes an expert system to diagnose some common and happened fault rapidly and accurately, which can greatly improve the management and maintenance of electric operating table. Introduction Electric operation table is a kind of basic medical device, which plays an important role in orthopedics, orthopedics and surgery. However, the majority of operating tables distributed in more than 400,000 medical institutions nationwide are still in the situation of no monitoring, no self-diagnosis, relying on professional staff to travel for maintenance and other conditions.There are limitations such as low safety in use, high maintenance cost, and difficulty in product r&d and upgrading. At the same time, electric operating table is a relatively complex electromechanical and hydraulic coupling system, which requires high professional requirements for maintainer and is difficult to maintain. So there is usually a large lag in maintenance. Once a part of the operating table malfunctions and fails to work properly, it will not only cause great economic losses, but even influence the normal operation and endanger the lives of patients. Therefore, there is an urgent need for a system to manage and maintain the electric operating tables, which can get the real-time status of tables to monitor, tracking and diagnose the operating tables. It not only can save expenses for medical institutions, but also provide more professional, safe and effective maintenance conveniently. The Overall Structure of the System As shown in the figure 1, the overall structure of the system is shown. Various sensors are used to obtain various operating parameters of each electric operating table, including operating posture, hydraulic system parameters, electrical system parameters, etc., which can be used for the status monitoring and fault diagnosis and analysis of the electric operating table. Wifi is used on each operating table to send the collected data to the gateway. A gateway can be set up in each medical institution or hospital to receive all terminal data of the operating table in the institution or hospital.
