Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a device for monitoring the presence of people in a room, sleeping, occurrence of fire, illegal entry into a room, etc.

[Conventional technology]

In large-scale structures such as offices, hotels, halls, and apartment complexes, for the purpose of monitoring the presence of personnel in specific rooms, occurrence of fires, and illegal intrusion into specific rooms, and providing services and management according to the monitoring status. ,Recently, infrared sensors emit infrared rays from the human body, or transmit vibration waves such as ultrasonic waves or radio waves, and receive reflected waves from objects based on this, and detect the movement of objects. The Doppler effect caused by
In addition to monitoring illegal intrusions, a general fire sensor is installed to separately detect the occurrence of a fire. Therefore, when using only an infrared sensor, there is a risk of false detection if there is a heat dissipating device or object in the room, and when using only a Doppler sensor, objects that move at low speed cannot be detected, and it is difficult to detect objects that move at low speed. On the other hand, it is impossible to detect a fire without installing a separate fire sensor, which is uneconomical, and it is also difficult to detect when a person in the room is asleep. This results in problems such as the inability to automatically change indoor air conditioning settings, control indoor lighting to turn off, etc.

[Means for solving problems]

In order to solve the above-mentioned problem, the present invention is implemented by the following means.
It is configured as follows.

In other words, there is a means for transmitting an out-of-out signal in response to a lock operation for going out, a plurality of infrared sensors that detect infrared rays emitted from objects in a specific room in each direction, and a means for transmitting vibration waves to the entire area within a specific room. When the detection outputs of the Doppler sensor, which receives reflected waves from an object based on vibration waves and detects the Doppler effect caused by the movement of the object, the infrared sensor, and the Doppler sensor, are generated almost simultaneously, a person enters a specific room. and a means for determining whether a person is in the room when the detection output of each of these sensors disappears, and a means for determining whether the person in the room is asleep when the detection output of the Doppler sensor disappears and the detection output of the infrared sensor decreases. , means for determining the occurrence of a fire when the detection outputs of infrared sensors occur almost simultaneously in multiple directions and exceed a certain value, and means for determining the occurrence of a fire when the entry/exit determination means determines that the room has entered after receiving an out-of-home signal. It is equipped with a means for determining.

[Effect]

Therefore, the combination of infrared sensors and Doppler sensors and locking operations can be used to determine whether there are people in a specific room, whether they are sleeping or not.
It is possible to reliably monitor fire outbreaks and illegal intrusions into specific rooms.

FIG. 2 is a plan view of room 1 and its surroundings, with lR82 and D
A PS3 is installed, and radio waves from the DPS3 are transmitted to the entire area of the room 1, and an IPS 2
In this case, each detection directivity of each sensor S1%Sn is beam-shaped, and these are arranged three-dimensionally in each direction of the room 1, and if there is an object that emits infrared rays in one of the rooms 1. If present, this infrared ray is detected in each direction.

Note that the 1R82 uses a differential type that generates a detection output according to changes in the amount of infrared rays that are incident on it. For example, the detection output gradually decreases.

In addition, TS4 is fixed to a wall, etc., and FCU6 is fixed to window 2.
2), the FCU 6 is equipped with a cooling or heating capacity that can be switched to three levels: H, M, and L (high, medium, and low). CNT 5 and SWB 7 are buried in the wall of 23, and
A KBll is similarly buried near the exit door 24, and the door 24 can be electrically locked or unlocked by inserting a key, identification card, or the like.

In addition, inside the room 1 and the bathroom 21, there are illumination lights and night lights (not shown in the figure), and power is turned on to them by relays in 6p and swBT.

OFF is controlled.

FIG. 3 is a comprehensive flowchart showing the monitoring and control status by the CPU 51 of the CNT 5.
, performs a "sleep judgment" 002 of the personnel in the room, and accordingly performs "lighting control" 011 for the SWB 7, and performs "room temperature control" 012 for the FCU 6, and then, based on the detection output of the lR82. After performing a "fire determination" 021 and further performing an "intrusion determination" 022 in response to the signal from the MCT 9 or KBll and the determination at step 001, steps 001 and subsequent steps are repeated.

FIG. 4 is a flowchart showing the details of step 001. If a person enters the room through the door 24, rDPs will be detected according to the movement of the person. If J101 is Y (YES), after the time rtl delay 102 by the timer configured in the CPU 51 has elapsed, the fi
If "IR8 detection? J 111" is Y, in order to maintain certainty, r DPS detection?" 112 is further checked, and "occupancy flag set" 121 is performed in accordance with Y.

Moreover, if step 111 or 112 is N (No), "occupancy flag reset" 122 is performed.

Note that when step 101 is N, step 1
Move to 11.

Therefore, if the detection outputs of IR82 and DPS3 occur almost simultaneously, it is determined that a person has entered the room, and the "occupancy flag" is set.
If each detection output of S3 disappears, it is determined that a person has left the room, and the "room occupancy flag" is reset, and the situation of personnel leaving the room is indicated according to these seven lags.

FIG. 5 is a 70-chart showing the details of step 002. When the occupants go to bed, their movements slow down.

If J212 is Y, "sleep flag set" 221 is performed, whereas if step 201 is Y or either step 211 or 212 is N, "sleep flag reset" 22 is performed.
Do step 2.

Therefore, the detection output of DPS3 disappears, and lR
When the detection output of 82 falls to a predetermined value, it is determined that it is time to go to bed, and this situation is indicated by a "sleep flag".

FIG. 6 is a flowchart showing the details of step 011. In response to steps 121 and 122, "occupancy flag set? J301 is determined, and if this is Y, 5WI

Through the time "t4 delay" 312 by the timer in U51, the main lighting is turned off J313 under the control of 5WB7, and only the night light is turned on.

On the other hand, when step 311 is N, [main illumination 0N
J314 lights up things other than the night light.

In addition, if step 301 is N, the lighting power supply is turned off after passing through the same time delay 321 as in step 312.
Perform J322.

FIG. 7 is a flowchart showing the details of step 012. In response to steps 121 and 122, "occupancy flag set? J401 is determined, and if the flag is Y, FCU is
S is controlled to perform "forced operation by FCU -H" 402, and the detection output of Ta2 indicates "room temperature/within a certain range?"
If J403 becomes Y, r FCU -M turns ON/

Check 23.

If the result in step 423 is N, ON/OFF control 431 is performed by l'-FCU-L, and the timer in the CPU 52 determines whether the time rts has elapsed. Check J432,
When this becomes Y, "r FCU stop" 441 is performed.

Therefore, while step 403 is N, step 40

1 is repeated and steps 412 and 423 are repeated while Y, steps 421 and 422 are similarly repeated, and the night
A set pack is performed.

Furthermore, if step 423 becomes N due to leaving the room or taking a bath, step 431 is executed until t6 has elapsed, and the FCU 6 stops after t6 has elapsed, so the room temperature changes rapidly in a room where the user is absent for a short time. do not.

FIG. 8 is a flowchart showing details of step 021. r IR8 detected? If J501 is Y, then this becomes "Multiple simultaneous detection? J5020Y", these "Each detection output is above a certain value? Judge J503, and when this is also Y, K is the time rty delay by the timer in CPU51" 511, the I/754 immediately sends a "fire alarm transmission" 512 to the DPI9.

Therefore, detection outputs are generated almost simultaneously in multiple directions by any one of the sensors S1 to an of the lR82, and
If each of these detection outputs exceeds a certain value, it is determined that a fire has occurred, and this information is sent to the DPI9.
The PI 9 will notify the occurrence of a fire by displaying this information and sending out an alarm sound.

FIG. 9 is a flowchart showing the details of step 022. When you lock the door using KBII when you go out, an out-of-home signal will be sent. Out-of-house signal received?J601 is judged, and based on this Y, in response to steps 121 and 122, check the ``occupancy flag set?J602, and if both are Y, it is determined that an illegal intruder is in the room. DPI immediately via Kl/F54
9, "Send intrusion alarm" 611 is performed.

Therefore, after receiving the out-of-home signal, step 00
If it is determined that there is an entry based on 1, it is determined that there is an illegal trespass, and the KDEP 9 notifies the user of this fact in the same way as described above.

As described above, various judgments are made by the combination K of 9.lR82 and DPS3, and it is also determined whether the people in the room are sleeping, and various controls are optimally performed according to these monitoring results. 1. Comfortable living conditions and energy savings can be achieved.

In addition, DPI 9 displays the indoor monitoring status, and responds quickly to notifications of fire outbreaks and trespassing. 5 etc., labor-saving management of crowded rooms and prevention of disaster spread can be achieved with an economical configuration that does not require fire sensors.

However, instead of using a differential type as lR82, use one that continuously generates a detection output, and change the detection output by converting it into a CN.
The determination may be made at T5, and in this case, the room temperature is determined from the detection output from a metal plate or the like whose amount of infrared radiation changes depending on the room temperature, and the same effect can be obtained even if TS4 is omitted.

In addition to the FCU 6 and SWB 7, devices to be controlled may be selected depending on the situation, and as the CNT 5, a dedicated control judgment circuit configured with multiple ring logic circuits can be used instead of the CPU 51. Various modifications are possible.

〔Effect of the invention〕

As is clear from the above explanation, according to the present invention, it is possible to locally and reliably monitor the presence of people in a specific room, the occurrence of a fire, and illegal intrusion. A remarkable effect can be obtained in indoor monitoring.
