The inner wall 6 of the entrance hall 5 separates from the corridor 7. The corridor 7 continues to a back door 9 such as an arbitrary door through a back door 8.

The entrance 2 is provided with a sensor 10 which is a human body detecting means for detecting the presence of a human body by detecting infrared rays from the human body. The detection area 11, which is the detection area of the sensor 10, is set outside the entrance door 4. When a family member returns home, a customer visits, or a suspicious person tries to enter the house 1 through the front door 4, this includes the risks that are expected to pass through. The back door 9 is also provided with a sensor 12 similar to the sensor 10, and its detection area 13 is provided outside the back door 8.

The illumination of the house 1 is supplied from a power source 14 such as a commercial AC power source to a controller 15 which is a control means via a power line Lp. The controller 15 is attached to the wall 6 on the entrance hall 5 side near the entrance. The electric power supplied to the controller 15 is supplied to the plurality of illumination lamps 16, 17, 18, 19, 20 via the power line Lc. The illuminating lamp 16 is a gate lamp provided in the gate 3, the illuminating lamp 17 is for illuminating the entrance porch outside the entrance door 4, and the illuminating lamp 18 is for illuminating the entrance hall 5 inside the entrance door 4. The illumination lights 19 and 20 are for illumination of the corridor. The sensors 10 and 12 and the controller 15 are connected by a signal line Ls.

FIG. 2 shows the appearance of the controller 15. Switches (21, 22, 23, 24) for blinking each of the illumination lamps 16 to 20 shown in FIG. 1 are provided on the front side of FIG. 2 (A). The corridor switch 21 controls the lighting lamps 19 and 20 to blink. The entrance switch 22 controls the lighting lamp 18 provided in the entrance hall to blink. The switch 23 for the porch controls the lighting 17 provided on the entrance porch to blink. The gate light switch 24 controls blinking of the illumination lamp 16 provided in the gate 3. A crime prevention mode switch 25 and a forced termination switch 26 are provided below the controller 15. The crime prevention mode switch 25 is a switch for turning on / off the crime prevention function of the controller 15. When the crime prevention function is turned on, the upper lamp of the crime prevention mode switch 25 is turned on to indicate that "warning" is being performed. The forced termination switch 26 is a switch that forcibly terminates the state when the automatic lighting or the buzzer sounds in the crime prevention mode.

On the back side shown in FIG. 2B, a signal terminal 27 for connecting the signal line Ls of the sensors 10 and 12 shown in FIG. 1, a power line Lc to each of the illumination lamps 16 to 20, and a power source. A power terminal 28 for connecting the power line Lp to 14 is provided. The power supply for operating the sensors 10 and 12 is also supplied from the signal terminal 27.

FIG. 3 shows an internal configuration of the controller 15 shown in FIG. The power supply circuit 30 supplies the electric power supplied from the power supply 14 via the power supply line Lp to the load control circuits 31, 32, ..., 3n via the internal power line La. An output for controlling an illuminating lamp is derived from each of the load control circuits 31, 32, ..., 3n via the power lines Lc1, Lc2 ,. Each of the load control circuits 31, 32, ..., 3n is controlled by a signal output control circuit 41 implemented by a microcomputer or the like. Outputs from the load control switches 21 to 24 and the crime prevention mode switch 25 are given to the signal output control circuit 41. The signal output control circuit 41 is connected with a timer circuit 42, a signal output state indicator 43, a sensor signal discrimination circuit 44, and a constant voltage circuit 45. The timer circuit 42 is used to adjust the time when the signal output control circuit 41 controls the load control circuits 31, 32, ..., 3n when the crime prevention mode switch 25 is in the ON state. The signal output state indicator 43 displays the output state of each illuminating lamp. The sensor signal discriminating circuit 44 discriminates whether or not the sensor 10, 12 detects a human body in the detection area 11, 13 according to a signal input from the sensor 10, 12 shown in FIG. 1 through the signal line Ls. To do. The constant voltage circuit 45 supplies DC power whose voltage is stabilized to the signal output control circuit 41, the timer circuit 42, the signal status indicator 43, and the sensor signal determination circuit 44 via the DC power supply line Ld. The power supply for the sensor is also supplied from the constant voltage circuit 45 via the signal line Ls.

FIG. 4 shows the operation of the controller 15 having the internal configuration shown in FIG. 3 in the crime prevention mode. Starting from step a1, when the crime prevention mode switch 25 is operated in step a2, the detection signal from the sensor 10 is waited in step a3. When a human body that has entered the detection area 11 is detected, the timer circuit 42 shown in FIG. 3 is reset in step a4, and the time counting operation starts. First, in step a5, the illumination lights 19 and 20 which are illumination loads provided in the corridor 7 are turned on. In step a6, the output from the timer circuit 42 is monitored, and the process waits until a predetermined time has elapsed. Next, in step a7, the illumination lamp 18 which is the illumination load in the entrance hall 5 is turned on. Next, in step a8, the process waits for the timer circuit 42 to measure a predetermined time. Next, in step a9, the illumination lamp 17, which is the illumination load on the entrance porch, is turned on. Next, in step a10, the operation of the timer circuit 42 is stopped, and the process returns to step a2.

In the operation shown in FIG. 4, the illumination lamps 18 and 17 are turned from the illumination lamps 19 and 20 inside the house 1 toward the entrance 2 every time a predetermined time set by the timer circuit 42 elapses. Turn on sequentially. When the predetermined time set in the timer circuit 42 is, for example, about several tens of seconds, a suspicious person is given a psychological effect as if a person walks and lights up one after another and comes out.

FIG. 5 shows an internal structure of a controller according to another embodiment of the present invention. This structure is similar to the structure shown in FIG. 3, and corresponding parts are designated by the same reference numerals. It should be noted that the controller 50 according to the present embodiment is provided with the illuminance sensor signal discriminating circuit 51, and controls the illumination lamp in the crime prevention mode only at night. That is, the illuminance sensor signal discriminating circuit 51 is provided with a detection signal from the illuminance sensor for detecting the illuminance around the house 1 shown in FIG. 1 through the signal line Lx. The illuminance sensor signal discriminating circuit 51 discriminates whether or not it is night based on the illuminance sensor detection signal, and gives a signal representing the discrimination result to the signal output control circuit 41. The signal output control circuit 41 controls the crime prevention mode at night and when the crime prevention mode switch 25 is ON.

FIG. 6 shows a crime prevention mode operation performed by the controller 50 shown in FIG. Starting from step b1, the crime prevention mode switch 25 is operated in step b2. In the next step b3, the detection of a signal from the human body detecting sensor 10 is awaited. When it is detected, the process proceeds to step b4, and when the signal from the illuminance sensor is discriminated and it is detected that it is nighttime, the process proceeds to step b5. When it is determined that it is not nighttime, the process returns to step b2. Thereafter, the same operations as steps a4 to a10 in the operation shown in FIG. 4 are performed by steps b5 to b11.

FIG. 7 shows an operation according to another embodiment of the present invention. In this embodiment, a buzzer sounding operation is added to the embodiment shown in FIG. From step c1 to the following step c5, the operation is the same as step a1 to step a5 shown in FIG. In the state where the human body is detected in the detection area 11 and the illumination lamps 19 and 20 in the corridor are turned on, the buzzer sounds in step c6. Hereinafter, steps c7 to c10 are the same operations as steps a6 to a9 shown in FIG. At step c11, the timer circuit 42 is stopped and the ringing of the buzzer is stopped. The buzzer may be provided in the sensor 10 shown in FIG. 7, for example. In addition, the buzzer may be provided not only for intimidating a suspicious person, but also as a separate alarm for notifying an anomaly to a resident living in the house 1.

According to each of the above embodiments, when a suspicious person approaches the entrance 2 and enters the detection area 11, the sensor 10 detects the illuminating lights 17 to 20 from the inside to the outside of the house 1. The lights are turned on sequentially. A suspicious person assumes a state in which a family member appears at the front door, and thus has a psychological threatening effect. As a result, it is possible to realize an effective crime prevention system against intrusion from the entrance, which has a high ratio of crimes. Also, since the lights are turned on sequentially from the inside to the outside, or the buzzer is rung during that time, it does not cause annoyance to the neighbors even when operated when a customer visits or a family member returns home. In particular, when the family member returns home, the family member must quickly pass through the entrance door 4 and operate the forced termination switch 26 of the controllers 15 and 50 provided on the wall 6 in the entrance hall 5 to stop the crime prevention function operation. Since it is possible to do so, there is little annoyance to the neighbors even at midnight. In addition, the automatic lighting of the lighting and the buzzer ringing due to the crime prevention function may be automatically stopped after a certain period of time has passed since the sensor detection signal disappeared, assuming that a suspicious person may leave due to the threatening effect. is there . In addition, although the crime prevention function for the entrance 2 is realized in each of the embodiments, it is needless to say that the crime prevention function for the back door 9 can be realized similarly. Further, it goes without saying that when a human body is detected a certain number of times within a predetermined time, it is determined that a suspicious individual is detected and the crime prevention function is activated.

[0019]

[Effect of device]

 As described above, in the present invention, when the human body detecting means detects the presence of a human body within the predetermined detection area, the lighting load provided near the entrance of the house is sequentially turned on from the inside to the outside of the house. If the detected human body is due to a suspicious individual, let the suspicious individual assume that a householder is at home in the house and appears at the entrance / exit as if the lighting load was turned on. A threatening effect can be generated. Considering the tendency of past crimes, suspicious persons often intrude through the doorway when the doorway is unlocked, but the threatening effect of assuming that a householder is at home deters the suspicious person's intention and enhances the crime prevention effect. be able to. In addition, simply detecting the presence of a human body within the detection area does not cause an alarm such as blinking of a lighting lamp or buzzer, so it is possible to avoid annoying the neighbors when visiting the house or customers. it can.
