Description

  The present invention relates to a lighting device with a staircase sensor for lighting a staircase by turning on a lamp depending on the presence or absence of a detection target in a staircase space such as a staircase or a staircase and / or its landing. This achieves interlocking control between similar lighting devices installed on the floor.

As this type of lighting device with a sensor for stairs, there is one disclosed in Japanese Patent No. 3444088 (Japanese Patent Laid-Open No. 9-304548). FIG. 11 is a cross-sectional layout view of a building in which the lighting device with a sensor for stairs disclosed therein is arranged. Through the first landing 12a, the first staircase has a staircase 11a that communicates with the lower floor and a staircase 11b that communicates with the upper floor, and a corridor 14 on each floor through the entrance 10 of the staircase to the stairs 11a and 11b. It consists of staircases 13a and 13b for proceeding respectively (see FIG. 12). In addition, the second staircase includes a staircase 11c that communicates with the lower floor and a staircase 11d that communicates with the upper floor through the second landing 12b, and a staircase 11c and a staircase 11c that passes through the corridor 14 of each floor through the entrance 10 of the staircase.

Japanese Patent No. 3444088

  As described above, there is a case where a lighting device with a stair sensor having a human sensor for detecting the presence of a person on the upper and lower stairs is used independently. When such a conventional lighting device with a sensor for stairs is provided on each floor, the lighting devices installed on the upper floor and the lower floor operate independently without being linked to each other. For this reason, when you go up and down the stairs, the lighting is turned on after detecting the presence of a person, so the lighting in front of you turns on or brightens, so you feel a sense of incongruity that is threatened by light There was a thing. Also, depending on environmental conditions (such as a low ambient temperature), lighting may be delayed, such as lighting after a person tries to climb a staircase, causing a problem in visibility.

  The present invention has been made in view of the above points, and it is determined whether a person is going up or down a stairs and lighting the lighting devices on the upper and lower floors in advance. It is an object of the present invention to provide a lighting device with a sensor for staircase that has no sense of incongruity and good visibility.

  According to the lighting device with a stair sensor of the present invention, as shown in FIG. 1 and FIG. 2, the lighting device is disposed in the stair space, and the presence of the person in the lamp 3 and the staircase on the lower floor side The first stair sensor 2a for detecting stair, the second stair sensor 2b for detecting the presence of a person in the upper stair part, and the first and second stair sensors 2a, 2b. A control unit 4 for generating a lighting signal for the lamp 3 based on a human body detection signal; and a ballast 5 for lighting the lamp 3 based on a lighting signal for the control unit 4. When at least one of the sensors 2a and 2b detects the presence of a person, the control unit 4 performs the interlock control with the lighting device 1 installed on the upper floor side or the lower floor side when the lamp 3 is turned on. The interlock control unit 6 that transmits and receives the control signal of It is characterized in.

  According to the present invention, it is possible to perform interlock control between stair lighting devices installed on a plurality of floors. Further, according to the inventions of claims 2 to 5, the movement pattern of the human sensor that detects the presence of the person on the upper and lower stairs is used to estimate the movement of the person in the up and down directions, By turning on the lighting device on the lower floor, there is an effect that it is possible to provide a lighting control system for staircases with good visibility without a sense of incongruity for people going up and down stairs.

  FIG. 1 shows the configuration of a lighting control system for staircase applications according to a preferred embodiment of the present invention. As described in FIGS. 11 to 16 above, each lighting device 1 is a staircase landing that is arranged up and down in the order of the staircase 13a, the staircase 11a, the landing 12a, the staircase 11b, and the staircase 13b. A lower-floor human sensor 2a that is installed on the wall surface of 12a and uses the lower floor as a detection area from the landing 12a, and an upper-floor human sensor 2b that uses the upper floor as a detection area from the landing 12a, This is a lighting device with a staircase sensor in which a first human sensor 2 a and a second human sensor 2 b are disposed at both ends of the lighting device 1. Each lighting device 1 is connected by, for example, a two-wire signal transmission line 7. The wiring of each lighting device 1 to the signal transmission line 7 is preferably a bus wiring, but may be a cascade wiring.

  As shown in FIG. 2, the internal configuration of the lighting device 1 is arranged in the vicinity of the lamp 3 and one end side of the lamp 3 (see FIG. 13). The first stair detection sensor 2a having detection beams A to be detected in a plurality of detection areas including at least a detection area on the way, and the vicinity of the other end side of the lamp 3 (see FIG. 13) A second stair detection sensor 2b having a detection beam B for detecting the presence or absence of a person in the side staircase in a plurality of detection areas including at least a detection area in the middle of the staircase, and first and second stair persons A control unit 4 for generating a lighting signal for the lamp 3 based on a human body detection signal of the sense sensors 2a and 2b; and a ballast 5 for lighting the lamp 3 based on a lighting signal for the control unit 4. Or the second human sensor 2a, 2b for stairs When at least one of them detects a person, the control unit 4 turns on the lamp 3 and transmits / receives a control signal for performing interlock control with the lighting device 1 installed on the upper floor side or the lower floor side It has the interlocking control part 6 which performs.

  As the lamp 3, for example, a fluorescent lamp, and as the ballast 5, for example, an inverter lighting circuit is used. However, the lamp 3 is not limited thereto, and an incandescent lamp or a copper-iron type ballast may be used. The control unit 4 receives any one of the motion sensor 2a that looks down the stairs, the motion sensor 2b that looks up the stairs, and the lighting trigger signal from the interlock control unit 6, and has a certain holding time, The lamp 3 has a function of performing lighting control or dimming control. Here, when the control unit 4 performs dimming control, for example, when a person is detected, all the lights are turned on, and when a predetermined holding time elapses after no person is detected, the dimming lights are operated. In addition, when only lighting control is performed, the lamp is turned on when a person is detected, and is turned off when a predetermined holding time elapses after no person is detected.

  As shown in FIG. 1, addresses are allocated to the interlock control unit 6 of each lighting device 1 in order for each floor. Here, it is assumed that the lighting device address on the upper floor is its own address -1, and the lighting device address on the lower floor is its own address +1. Each lighting device 1 takes in if the signal on the signal transmission line 7 is a control signal for its own address. And the trigger signal of lighting is given with respect to the control part 5 with the content of the command of the received control signal. In addition, a lighting trigger signal is given to the interlock control unit 6 from the control unit 4 according to a pattern in which the two sensors 2a and 2b of the self-lighting device detect the human body, and the lighting device 1 on the upper and lower floors is controlled. Send a signal.

  As shown in FIG. 3 (a), the interlock pattern is a pattern 1, which is detected by a human sensor looking at the lower stairs and then detected by the human sensor looking at the upper stairs. A control signal is sent to light up.

  In pattern 2, as shown in FIG. 3B, after the human sensor looking at the upper stairs detects, the lower floor lighting device is turned on when the human sensor looking at the lower stairs detects. Send control signal to.

  As shown in any one of FIGS. 4A to 4D, the pattern 3 is illuminated on the upper and lower floors when a human sensor looking at the upper stairs and a human sensor looking at the lower stairs simultaneously detect. A control signal is sent to turn on the devices at the same time. The interlocking pattern is not limited to these patterns 1 to 3.

  The operation of the control unit 4 can be realized by a microcomputer. Flow charts relating to the control are shown in FIGS. FIG. 5 shows the flow of the main routine. In this main routine, an internal timer of the microcomputer periodically checks the detection state of its own human sensors 2a and 2b and the presence or absence of a lighting trigger signal from the interlock control unit 6. In # 1, it is determined whether or not a predetermined time has elapsed by an internal timer. Every time a certain time elapses, a series of processes # 2 to # 15 are executed.

  First, in # 2, it is confirmed whether or not the holding time has passed. If the holding time has passed, the process branches to # 3 to turn off its own illumination and shift to # 4. If the holding time has not elapsed in # 2, # 3 is skipped and the process proceeds to # 4. Here, in order to determine whether or not the holding time has passed in # 2, for example, the holding time count value set in # 6, # 10, # 14, etc. is decremented by 1 and counted. If the value becomes 0, it can be realized by using a known method for determining that the holding time has elapsed.

  In # 4, in order to compare and judge the change in the detection state of the own upper / lower sensors 2a and 2b (in the subroutine of # 15 later), the previous detection state of the upper / lower sensor (up / down sensor) Flag) is copied to another memory area (old upper / lower sensor flag).

Next, at # 5 to # 12, the detection state of the self upper / lower sensor is confirmed, and the upper / lower sensor flag is rewritten.
In # 5, the detection state of the lower sensor 2a of the self is confirmed. If the lower sensor is in the detection state, the process branches to # 6 to turn on its own illumination and set the holding time. Store as flag = 1. If the lower sensor is not detected in # 5, the lower sensor flag = 0 is stored in # 8.

  In # 9, the detection state of the upper sensor 2b of the self is confirmed. If the upper sensor is in the detection state, the process branches to # 10 to turn on its own illumination and set the holding time. Store as flag = 1. If the upper sensor is in the non-detection state in # 9, the upper sensor flag = 0 is stored in # 12.

  In # 6 or # 10, when the self-illumination was originally turned on, the lighting state is maintained as it is, and only the holding time is updated to the initial value. Therefore, the illumination is turned on for a predetermined holding time after the lower sensor or the upper sensor detects a person at the end.

  Next, in # 13, it is confirmed whether or not there is a lighting trigger signal from the interlock control unit. If there is a lighting trigger signal in # 13, the process branches to # 14 to turn on its own illumination and set the holding time. Note that the holding times set in # 6, # 10, and # 14 may be different values or the same value.

  Next, in # 15, a subroutine for determining a change in the detection state of the upper / lower sensor is executed. The contents of this subroutine are shown in FIG. In the figure, “up / down” means “upper sensor flag / lower sensor flag” detected this time, and “old upper / lower” means “old upper sensor flag / old lower sensor flag” detected last time. Means. Further, “1” of “0/0, 0/1, 1/0, 1/1” means “detection”, and “0” means “non-detection”.

  First, the subsequent processing branches depending on whether the old upper sensor flag / old lower sensor flag is 0/0, 0/1, 1/0, or 1/1, respectively.

(1) When the old upper sensor flag / old lower sensor flag is 0/0, if the current upper / lower sensor flag is 1/1, both sensors detect that It is determined that there is a person coming down, and a lighting trigger signal for the upper and lower lighting devices is output to the interlock control unit. Other than that, since there is no change across the upper and lower sensors, the lighting trigger signal is not output to the interlock control unit.

(2) When the old upper sensor flag / old lower sensor flag is 0/1, when the current upper / lower sensor flag is 1/1, both sensors detect that It is determined that there is a person coming down, and a lighting trigger signal for the upper and lower lighting devices is output to the interlock control unit. When the current upper / lower sensor flag is 1/0, it is determined that there is a person going up the stairs, and a lighting trigger signal for the upper lighting device is output to the interlock control unit. Other than that, since there is no change across the upper and lower sensors, the lighting trigger signal is not output to the interlock control unit.

(3) When the old upper sensor flag / old lower sensor flag is 1/0, if the current upper / lower sensor flag is 1/1, both sensors have detected, It is determined that there is a person coming down, and a lighting trigger signal for the upper and lower lighting devices is output to the interlock control unit. When the current upper / lower sensor flag is 0/1, it is determined that there is a person going down the stairs, and a lighting trigger signal for the lower lighting device is output to the interlock control unit. Other than that, since there is no change across the upper and lower sensors, the lighting trigger signal is not output to the interlock control unit.

(4) When the old upper sensor flag / old lower sensor flag is 1/1, if the current upper / lower sensor flag is 0/1, it is determined that there is a person going down the stairs, A lighting trigger signal for the lighting device is output to the interlock control unit. When the current upper / lower sensor flag is 1/0, it is determined that there is a person going up the stairs, and a lighting trigger signal for the upper lighting device is output to the interlock control unit. Other than that, since there is no change across the upper and lower sensors, the lighting trigger signal is not output to the interlock control unit.

  As the operation of the interlock control unit 6, the detection information (lighting information) of the human sensor is sequentially transmitted between the lighting devices of the addresses 1 to N in a time division manner. The period at which the lighting devices of addresses 1 to N complete transmission sequentially is set to be a sufficient speed in consideration of the movement speed of humans when performing interlock control on the upper and lower floors. For example, when transmitting a signal for each lighting device in units of 1 msec, in the example of N = 100 units, the total transmission time of 1 to 100 units is 0.1 seconds, and going up the stairs in 0.1 seconds is Since it is considered impossible, it can be said that it will not interfere with the interlocking control.

  Here, the format of the control signal is illustrated in FIG. In this example, it consists of its own address (for example, 6 bits) and a command (for example, 2 bits) for instructing lighting / maintenance (no change) to the lighting devices on the upper and lower floors.

  In the main routine of the interlock control unit 6, whether the signal is automatically received by the communication IC (such as UART) and the signal is received by periodically polling the contents of the IC buffer. Confirm. The flow of processing related to signal transmission / reception is shown in FIG. 8, FIG. 9, and FIG.

  In FIG. 8, if it is determined that a signal has been received, the process jumps to the signal reception subroutine (FIG. 9), and after completing the signal reception process, if it is a received signal from its own address-1, the order in which it transmits the signal. And jump to the signal transmission subroutine (FIG. 10). These series of processes are repeatedly executed.

  In the signal reception subroutine (FIG. 9), first, if it is a signal from its own address-1, if the lighting device lighting flag on the lower floor in the signal format shown in FIG. Output. If the signal is from the own address +1, if the lighting device lighting flag on the upper floor in the signal format shown in FIG. 7 is 1, a lighting trigger signal is output to the control unit 4. A series of these processes is performed, and the process returns to the main routine (FIG. 8).

  Next, in the signal transmission subroutine of FIG. 10, if there is an upper floor lighting trigger signal from the control unit 4, the upper floor lighting device lighting flag in the signal format shown in FIG. If there is no upper floor lighting trigger signal from the control unit 4, the lighting device lighting flag on the upper floor in the signal format shown in FIG. If there is a lower floor lighting trigger signal from the control unit 4, the lower floor lighting device lighting flag in the signal format shown in FIG. If there is no lower floor lighting trigger signal from the control unit 4, the lower floor lighting device lighting flag in the signal format shown in FIG. Then, the data in FIG. 7 is written into the transmission buffer of the communication IC, and a signal is transmitted.

  With the above configuration, the movement pattern of the human sensor that detects the presence of people on the upper and lower stairs is used to estimate the person's upward and downward movement, and the upper and lower floor lighting devices are turned on in advance. By doing so, it is possible to provide a lighting control system for staircases with good visibility without a sense of incongruity for those who go up and down stairs.

  In the system configuration examples of FIGS. 1 and 2, the lighting devices 1 are connected by a two-wire signal transmission line 7, but the control signal communication means is replaced by a wired method and is wireless. It is good also as a system.
