an air sampler 110, an ultraviolet sterilizing lamp 120, a sensing module 130 and a control module 140;
the air sampler 110 is used for detecting the temperature, the humidity and the colony number in the air of a department to be sterilized;
the ultraviolet sterilization lamp 120 is used for releasing ultraviolet rays to sterilize and sterilize the departments to be sterilized;
the sensing module 130 is used for sensing whether the department to be killed meets the killing condition;
the control module 140 is configured to receive signals from the air sampler 110 and the sensing module 130, and control the on/off of the ultraviolet germicidal lamp 120;
the control module 140 is electrically connected to the air sampler 110, the ultraviolet germicidal lamp 120, and the sensing module 130, respectively;
the air sampler 110 converts the detected temperature, humidity and colony number in the air of the department to be sterilized into an air parameter signal and transmits the air parameter signal to the control module 140; the sensing module 130 converts the sensed result of whether the department to be killed meets the killing condition into a condition signal and transmits the condition signal to the control module 140; the control module 140 controls the ultraviolet germicidal lamp 120 to be turned on and off based on the air parameter signal and the condition signal.
In one embodiment of the present description, the air sampler 110 may be selected from a six-stage impingement air sampler or other validated air sampler. The control module 140 calculates the disinfection duration according to the air parameter signal of the air sampler 110. After the ultraviolet sterilizing lamp 120 finishes sterilizing, the department to be sterilized meets the hospital sanitation standard.
The ultraviolet sterilizing lamp 120 can be a low-pressure mercury vapor discharge lamp made of quartz glass or other purple glass, and the ultraviolet sterilizing lamp 120 discharges to generate ultraviolet radiation mainly with the wavelength of 253.7nm, so that RNA and DNA of microorganisms such as bacteria are broken, the replication and survival capabilities of the microorganisms are lost, and the aim of sterilization and disinfection is fulfilled.
The ultraviolet killing lamp 120 may be installed on an indoor wall or a top of the department to be killed, in one embodiment of the present specification, a movable bracket may be installed on an indoor ceiling of the department to be killed, the ultraviolet killing lamp 120 is installed on the movable bracket, the control module 140 controls the movement of the ultraviolet killing lamp 120 by controlling the movement of the movable bracket, so as to achieve the purpose of uniformly killing the department to be killed, and in another embodiment of the present specification, a plurality of ultraviolet killing lamps 120 are arranged at intervals on the top in the room of the department to be killed.
In view of the potential for damage to the skin and eyes of a human being from direct exposure to the radiation from the ultraviolet germicidal lamp 120, in one embodiment of the present description, the sensing module 130 includes a human body sensing sensor 132. Whether a human target exists in the department to be sterilized is sensed through the human body sensing sensor 132, once the human target exists, the human body sensing sensor 132 transmits a signal for sensing that the human target exists in the department to be sterilized to the control module 140, and the control module 140 immediately turns off the ultraviolet ray sterilizing lamp 120 so as to avoid the situation that the human target is burnt by ultraviolet rays.
The human body induction sensor 132 is electrically connected to the control module 140 for sensing a human body target of the department to be disinfected. In one embodiment of the present disclosure, the human body induction sensor 132 is an infrared sensor installed on a wall of the department to be disinfected, and preferably, the infrared sensor is installed at a corner of the wall of the department to be disinfected.
In another embodiment of the present disclosure, the body-sensing sensor 132 is a radar sensor installed on the top of the department to be disinfected. .
Because ultraviolet sterilization is performed after workers in the department to be sterilized leave work, the probability that the department to be sterilized has a human body target is low, the human body induction sensor 132 is turned on for a long time or continuously, energy is consumed, and if workers exist in the department to be sterilized, the skin of a human body is damaged due to long-time infrared radiation. In an embodiment of the present disclosure, the sensing module 130 includes a door opening/closing sensing sensor 131, which can sense an entrance door of the department to be disinfected and killed, and further determine whether a worker enters the department, so as to reduce injury caused by long-time infrared radiation.
The door opening and closing sensing sensor 131 is installed on the entrance door of the department to be disinfected and killed, and is electrically connected to the control module 140, and is used for sensing whether the entrance door is in a closed state. In one embodiment of the present specification, the door opening and closing sensing sensor 131 is a door and window sensor, which may be made based on the reed pipe principle. The reed switch is usually made of soft magnetic material, and in the case of no magnetic field at the periphery, the two contacts are separated, and when the reed switch is magnetized by the magnetic field, the two contacts are contacted, so that the circuit is closed. If a magnet is arranged beside the door, when the magnet is close to the reed pipe, the circuit can be switched on, when the magnet is far away from the reed pipe, the circuit can be switched off, if the magnet is fixed on the door, and the reed pipe assembly is fixed on the door frame close to the magnet, the circuit can be switched on when the door is closed, and when the door is opened, the circuit is switched off, and therefore the sensing of the opening and closing states of the door is realized. In another embodiment of the present specification, the door opening and closing sensing sensor 131 may be a displacement sensor.
In order to improve safety in consideration of the possibility that workers may enter a department when the department is in the process of killing, in one embodiment of the present specification, a feedback switch 150 is installed outside the department, the control module is electrically connected to the feedback switch 150, and the feedback switch 150 controls the turning off of the ultraviolet killing lamp 120 through the control module 140. When ultraviolet ray sterilization is being performed in a department, if a worker needs to enter the department, the feedback switch 150 can be pressed, and the control module 140 immediately turns off the ultraviolet ray sterilization lamp 120 to prevent the worker from contacting ultraviolet rays.
In consideration of the fact that the illumination lamp of the department to be sterilized is always on during the ultraviolet sterilization, which may cause the photo-revival of microorganisms, in one embodiment of the present specification, the control module 140 is electrically connected to the illumination lamp of the department to be sterilized for controlling the illumination lamp to be turned off. The sterilizing efficiency of the ultraviolet sterilizing lamp 120 is improved.
Fig. 2 is a schematic diagram of an ultraviolet disinfection method for hospital departments according to an embodiment of the present disclosure, the method including:
the S21 control module acquires the current time in real time and judges whether the current time meets the preset killing time;
it is appropriate that the ultraviolet sterilization is performed after the workers in the department to be sterilized leave work, and the preset sterilization time may be set manually, and preferably, the preset sterilization time is 22: 00.
s22, when the current time accords with the preset killing time, the human body induction sensor induces whether a human body target exists in a department to be killed, and the human body induction sensor transmits a signal that the department to be killed does not have the human body target to the control module;
since ultraviolet ray sterilization must be performed without a person, it is first determined whether a human target is present in the subject room to be sterilized. When the current time accords with the preset killing time, the control module informs the human body induction sensor to start to induce whether a human body target exists in the department to be killed;
if the human body induction sensor senses that the department to be killed does not have a human body target, the human body induction sensor transmits a signal that the department to be killed does not have the human body target to the control module, and the control module closes the human body induction sensor;
if the human body induction sensor induces that the department to be killed has a human body target, the human body induction sensor transmits a signal that the department to be killed has the human body target to the control module, but the control module does not turn on the ultraviolet ray killing lamp to carry out ultraviolet ray killing on the department to be killed based on the signal of the human body induction sensor.
The human body induction sensor induces whether the department to be killed has a human body target or not at intervals of time X, and the time X can be manually set.
In another embodiment of the present disclosure, when the human body sensor senses that the department to be killed has a human body target, the human body sensor transmits a signal that the department to be killed has the human body target to the control module, the control module notifies the door opening and closing sensor to sense whether an entrance door of the department to be killed is in a closed state, when the entrance door is in the closed state, the human body sensor senses whether the department to be killed has the human body target after time Y in consideration of time taken by a worker to go out from the department to be killed when the entrance door is opened, and the time Y may be manually set. If the human body induction sensor induces that the department to be killed has a human body target, the human body induction sensor transmits a signal that the department to be killed has the human body target to the control module.
S23 door opening and closing induction sensor senses whether the door of the department to be sterilized is closed or not;
considering that the air circulation speed is different when the entrance door is in the opening and closing state, and whether a human body target exists in the department to be killed or not can be indirectly judged through the entrance door in the killing process, the human body target detection efficiency is improved, therefore, when the department to be killed or not does not have the human body target, the control module informs the door opening and closing induction sensor to sense whether the entrance door of the department to be killed or not is in the closing state.
S231, the door opening and closing induction sensor transmits a signal that the entrance door is in a closed state to the control module;
considering the influence of air ventilation and the like on ultraviolet sterilization, when the entrance door of the department to be sterilized is in a closed state, the air circulation of the department to be sterilized is slow, and the ultraviolet sterilization is facilitated.
S25, the control module turns on an ultraviolet sterilization lamp and carries out ultraviolet sterilization on the department to be sterilized according to the sterilization duration;
after the control module receives the signal that the department to be killed does not have the human body target and the signal that the entrance door is in the closed state, the control module confirms that the department to be killed can carry out ultraviolet ray killing, then the control module turns on the ultraviolet ray killing lamp, carries out ultraviolet ray killing on the department to be killed according to the killing duration, regularly kills the department to be killed through the control module, and the labor cost is effectively reduced.
