Description

Display control system and method

The invention relates to a display control system and method.

The patient information on the traditional bedside card is generated by handwriting or printing. When the information must be updated frequently, it will be very inconvenient. Moreover, the patient's information involves personal privacy and should not be explicitly disclosed to other unrelated persons.

The disadvantage of the prior art is that the electronic bedside card still cannot effectively solve the problem of patient privacy. That is, it cannot be achieved that only medical staff or physicians can activate the electronic bedside card to display private information, and those who are interested have the opportunity to use the electronic bed. The header card sends malicious code to the server host to modify, delete or steal basic information of the hospital or patient, or even deliberately cause the server host to malfunction.

In view of the foregoing, it is necessary to provide a display control system and method that can achieve personal information security and personal privacy confidentiality, and can also effectively save power, reduce costs, and meet the needs of green environmental protection.

A switch module, the switch module electrically connects or disconnects the power supply module and the wireless tag reader;

A sensor, which is used to detect changes in the magnetic field of the proximity card; and

A processor, the processor is electrically connected to the wireless tag reader and the sensor;

When the sensor detects a change in the magnetic field, it outputs a detection signal to the switch module to turn off the switch module, the power supply module supplies power to the wireless tag reader, and the processor The identification code of the proximity card is sent to the server to query the user's authority, and different authority information is displayed according to the user's authority.

An embodiment of the present application also provides a display control method. The display control method includes the following steps:

Detect the magnetic field change of a proximity card;

Supply power to the wireless tag reader;

Sending the identification code of the proximity card to a server to query the user's authority; and

Different authority information is displayed according to the user's authority.

In the display control system and method provided by the implementation of this application, the bedside card can control peripheral devices to display different information content (such as confidential or personal privacy information) in real time according to the permissions of different users, so as to achieve real-time and safe information display. purpose. When the bedside card is idle, that is, when the sensor does not detect a change in the magnetic field, the power supply module does not supply power, thus effectively saving power. When the proximity card is close to the bedside card, the magnetic field change is detected through the sensor to turn on the power supply of the power supply module, so that the bedside card performs identity authentication on the proximity card. Therefore, the bedside card can not only ensure normal operation, but also can effectively save electric energy, reduce the cost, and meet the needs of environmental protection.
