Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the utility model, its application, or uses.

To maintain the following description of the embodiments of the present invention clear and concise, a detailed description of known functions and known components of the utility model have been omitted.

Referring to fig. 1, in this embodiment, there is provided an interlock control system for a buffer chamber of a biosafety laboratory, including: buffer room, include: the control device comprises a central monitoring device 12 and a control box 8 connected with the central monitoring device 12, the first buffer door 1 and the second buffer door 2 both comprise door bodies, the door bodies are provided with a switch button 3 and a door magnetic switch 6, the switch button and the door magnetic switch are connected with a digital quantity input end 10, and the door bodies are provided with electromagnetic locks 5 connected with a digital quantity output end 11.

It should be noted that all the electric devices referred to in this application may be powered by a storage battery or an external power source.

Through the central monitoring device 12 who sets up, can control first buffering door 1 and second buffering door 2 intelligence at every turn and open a door simultaneously to reduced and opened the door and aroused the air current disturbance in the laboratory, also be convenient for, central monitoring device 12 monitors the statistics to the condition of opening of door between the laboratory buffering, knows personnel's circumstances of cominging in and going out in real time, and then improves the air current controllability in the laboratory, has reduced a plurality of buffering doors and has opened and the air current that causes leaks.

One side of the control box 8 of this embodiment is provided with a digital input end 10 and a digital output end 11; the first buffer door 1 and the second buffer door 2 are connected in parallel on the control device; the door body is provided with an emergency unlocking button 4 connected with a digital input end 10.

The door body of the embodiment is provided with a card reader 7 connected with a digital input end 10; and an audible and visual alarm 9 positioned between the first buffer door 1 and the second buffer door 2 is connected to the digital quantity output end 11. Through audible and visual alarm 9 who sets up, can not close at the door, can report to the police the suggestion, avoid causing the air current in the laboratory to leak.

Specifically, this uses a novel control principle:

this system is the design of double-door interlocking control system, by between communicating first buffering and second buffering, between two cushions constitute, first buffering door 1 and second buffering door 2 are installed respectively on two cushions within a definite time, and the door between two cushions can't be realized opening simultaneously.

When the card reader 7 of the first buffer room senses an entrance guard card, the switch button 3 is pressed, at the moment, the switch button 3 and the card reader 7 respectively transmit signals to the control box 8 through the digital input end 10, and the control box 8 gives out a signal of the digital output end 11 to control the electromagnetic lock 5 to act to open the door of the first buffer room.

At the moment, a person enters the second buffering room, under the condition that the door of the first buffering room is closed, the control box 8 receives a signal of the digital quantity input end 10 of the door magnetic switch 6 and gives a signal of the digital quantity output end 11 to control the electromagnetic lock 5 of the second buffering room to act, and at the moment, the person can open the door of the second buffering room.

If the door of the first buffer room is not closed, the door magnetic switch 6 cannot give a signal of the digital quantity input end 10, the electromagnetic lock 5 of the second buffer room cannot be controlled to act, and the door of the second buffer room cannot be opened.

If the door of the first buffer room is not closed, the door of the second buffer room can not be opened, and at the moment, the control box 8 gives out a signal of a digital quantity output signal end 11 to control the audible and visual alarm 9 to give an alarm so as to give an alarm.

All the actions are fed back to the central monitoring system 12 through the control box 8, and the opening condition of the buffer room door is monitored in real time and the air flow control condition is monitored through the display of the central monitoring system 12.

If the biological safety laboratory core laboratory exits, the biological safety laboratory core laboratory enters the first buffer room from the second buffer room and exits, and the control path is consistent with the control path.

When the interlocking door system breaks down or accidents such as fire control occur, the emergency unlocking buttons 4 on the two buffer doors can be manually opened to forcibly open the interlocking door system, so that the emergency escape function is realized.
