[0020] Figure 2 It is a partially enlarged schematic diagram of the zone controller and the access control device in an embodiment of the present invention. DETAILED DESCRIPTION

[0021] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0022] The technical solution of the present invention provides a buffer room interlocking system for an infectious disease area of ​​a hospital ship, comprising:

[0023] At least one master controller is connected to the zone controllers by wire or wirelessly.

[0024] There are multiple zone controllers, each zone controller is connected to the main controller by wire or wireless, and each zone controller is connected to the main controller by wire or wireless. There are multiple access control devices in the area corresponding to each zone controller, and each access control device is connected to the zone controller by wire or wireless.

[0025] Display and control equipment, connected to the main controller by wire or wirelessly.

[0026] The main controller, regional controller and display and control equipment can communicate in real time and bidirectionally to transmit control commands and status information in real time.

[0027] In one embodiment of the present invention, a buffer room interlocking device is provided, which mainly includes a control box (equivalent to a master controller), a remote control display (equivalent to a display and control device), a plurality of area controllers (depending on the control range), a plurality of access control devices and a plurality of single / double door lock devices. The overall block diagram of the device system is shown as follows: Figure 1 to Figure 2 As shown: The control box is powered by AC220V. There is a switching power supply from AC220V to DC12V inside the control box. The control box converts AC220V into DC12V. The control box provides AC220V power to the regional control box on the one hand, and DC12V power to the remote controller on the other hand.

[0028] In this embodiment, the remote control display sends the preset door opening condition instruction, which is transmitted to the control box via Ethernet. The control box sends it to the regional controller via Ethernet. The regional controller performs logical judgment based on the received door opening and closing conditions, card swiping information and door status information, and then controls the hatch door to open. The main controller is connected to the ship's fire alarm system by wire or wireless. An alarm board is set inside the main controller. When the fire alarm system detects a fire, the main controller can receive the fire alarm information in real time. Once a fire alarm signal is received, the fire alarm signal will be sent to each regional controller via Ethernet. The regional controller will release all hatch door interlocks in the buffer room and allow the hatch door to open so that people on board can escape.

[0029] In one embodiment of the present invention, RS485 communication is adopted between the zone controller and the access control device. When the zone controller receives the door status signal of the door lock device, the door status indicator light of the zone controller operation panel will be displayed according to the door status information. After receiving the card swiping information, the zone controller will perform logical judgment based on the door status information and the received door opening and closing conditions to determine whether the cabin door can be opened. At the same time, the zone controller and the control box adopt Ethernet communication, and these data will be uploaded to the control box for data processing.

[0030] When the controller receives data from the zone controller, it will process and transmit the received data to the remote control display, which will process and store the received information. For example, the door status signal is displayed on the main screen, and the status of each door in the buffer room can be intuitively seen. The access control information will be stored in a special control (if you want to query, click the record query control, we can set the time period or enter the personnel information for on-demand query).

[0031] There is an alarm panel in the control box that can receive external fire alarm signals in real time. Once a fire alarm signal is received, the alarm panel will transmit the signal to each area control panel via Ethernet. Once the area controller receives the fire alarm signal, it will release all access interlocks in the area and allow the hatch to open to facilitate the escape of people on board. At the same time, the alarm panel will transmit the alarm signal to the remote control display via Ethernet for alarm reminder.

[0032] As a further optimization of the above embodiment, when the entire equipment fails or the ship is in a power-off state, the entire system will close the interlock control and allow the interlock door of the entire buffer room to be opened to facilitate personnel to enter. The interlocking device can manage the authority of medical staff and control the authority of personnel to enter the isolation ward or buffer room. Those who do not obtain the corresponding authority of the ward or buffer room cannot enter. Among them, the authority management is carried out through the identity recognition device, and the identity recognition methods that can be used by the identity recognition device include fingerprint recognition, face recognition and ID card recognition.

[0033] As a further optimization of the above embodiment, the control box also communicates with the platform information network, medical information network and air-conditioning, ventilation and infection control equipment on the hospital ship to obtain information in real time and control the air-conditioning, ventilation and infection control equipment to ventilate each area in time.

[0034] The technical solution of the present invention also provides a hospital ship, and the above-mentioned interlocking system is arranged between the buffer rooms of the infectious disease areas of the hospital ship.

[0035] The above are preferred embodiments of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
