At this time, it is preferable that the control means 30 and the management center can increase the compatibility in the building control by using MODbus RS-485, which is a universal communication system.
In order to manage the buildings optimized for the occupants, such as the information about the building where the indoor space I is located, the size information of the indoor space I, and the ventilation amount information necessary for one occupant of the indoor space I, It is preferable that a database (DB) in which information is stored is provided, and the control means (30) or a separate management center is electrically connected to the database (DB).
Through the database (DB) storing various kinds of management information, it becomes possible to manage the building according to the vacancy of the building or the low occupancy rate, and it is possible to save the energy by preventing the unnecessary use of energy.
In addition to air conditioning, the
Hereinafter, the operation of the occupant counting apparatus according to the embodiment of the present invention will be described.
FIG. 4 is a state diagram illustrating a use state of the occupant counting apparatus according to the first embodiment of the present invention.
First, as shown in Fig. 4, on both side walls of the entrance E, parallel to the direction of movement of a person moving through the entrance E, is provided parallel to the direction of movement of the person E, A pair of first sensing means 10 is arranged.
When a person enters and exits through the entrance E in this state, the light emitted from the first sensing means 10, for example, infrared rays, is sequentially intercepted with a time difference. That is, when a person does not pass, the infrared rays emitted from the
In the case of a person entering the interior space according to the moving direction of the person, the
On the contrary, in the case of a person leaving the indoor space, the
Accordingly, when a person enters the indoor space, the
The control means 30 receives the information counted by the
Then, when the person enters or leaves the indoor space, the control means 30 controls the
At this time, the control means 30 judges that the occupancy number of the indoor space is 0, that is, the occupancy number of the indoor space is 1, and the occupant number When the number of departing persons is one in the information counted by the
On the contrary, when it is judged that the occupancy number of the indoor space is one for the first time, that is, the occupancy number of the indoor space is 0, the occupant number is 1 in the information counted by the
FIG. 5 is a state diagram showing the use state of the occupant counting apparatus according to the second embodiment of the present invention.
The
That is, if a person is detected only by the second sensing means 40 or only by the third sensing means 50, the information sensed by the second sensing means 50 is ignored, The
However, when the person is sensed by both the second and third sensing means 40 and 50, the
After the counter 20 counts the number of persons sensed by the second sensing means 40, the number of persons who enter or leave the interior space according to the order of sensing by any one of the third sensing means 50 Lt; / RTI > again.
For example, when a person leaving in the indoor space and a person entering into the indoor space are staggered at the doorway E, or two persons out of the indoor space exit at the doorway E at the same time, A person may be detected in both the second sensing means 40 and the third sensing means 50 in a situation where the user enters the room at the same time.
At this time, the moving direction of the person detected through the second sensing means 40 and the third sensing means 50 is independently detected, and the
In other words, when the person leaving and the person entering the hall are struck, the entrance hall counter 22 counts the number 1, the
If there are two persons leaving the hall at the same time, only the exit number counter 24 counts the number 2, and if there are two persons entering at the same time, the entrance number counter 22 counts the number 2 only. Accordingly, the control means 30 computes -2 in the current occupant space or calculates +2 to determine the occupant in the occupant space.
The scope of the present invention is not limited to the above-described embodiments, but may be embodied in various forms of embodiments within the scope of the appended claims. It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the present invention as defined by the appended claims.
