Hereinafter, a lighting device with a built-in life pattern and P2P-based fire detection function according to a preferred embodiment of the present invention will be described with reference to FIGS. 1 to 5 attached hereto. 1 is a schematic view of a smart lighting system having a life pattern and a P2P-based fire detection function according to a preferred embodiment of the present invention. Fig. 2 shows a functional block diagram of the illumination lamp of Fig. 3 is a block diagram of the main function of the MCU of FIG. Fig. 4 is an example of a smoke concentration / time graph of life smoke and fire smoke. 5 is an example of a life delay information table. For convenience of explanation, it is explained based on multi-family house. Of course, the following can be applied to all compact houses such as multi-family homes.

Referring to FIG. 1, a multi-family house may include a plurality of households (100-1, 100-2, 100-3, ..., 100-n, hereinafter collectively referred to as "100"). Each of the plurality of generations (100) may include a lighting device (200). Each lighting device 200 can communicate with each other via the communication network 300. At this time, the communication network 300 may be a LAN (Local Area Network). The illuminating device 200 connected to each other through the communication network 300 can share information for fire detection and reference value correction and generate information for fire detection and reference value correction. That is, from the viewpoint of information for fire detection and reference value correction, each lighting apparatus 200 can perform a peer function. The plurality of lighting apparatuses 200 may be connected to each other through the communication network 300 to form a Peer To Peer (P2P) network.

Referring to FIG. 2, the illumination device 200 installed in each of the plurality of generations 100 can operate on a generation-by-generation illumination system as shown in FIG. The lighting system may include a lighting device 200, power supply lines L1 and L2. The lighting apparatus 200 may include a power supply unit 210, an MCU 220, a lighting unit 230, a communication unit 240, and a switch monitoring unit 250. In Fig. 2, the reference symbol " L1 " may refer to a first power supply line, and " L2 " may refer to a second power supply line. The lighting system may include a third power supply line L3 branched from the first power supply line L1 and a fourth power supply line L4 branched from the second power supply line L2. A wall switch SW may be provided on the first power supply line L1. For example, the wall switch SW may be a switch installed in the living room. AC power may be supplied through the first power supply line L1 and the second power supply line L2.

The switch monitoring unit 250 may receive power through the first power supply line L1 and the fourth power supply line L4. The wall switch SW can control the power supplied to the switch monitoring unit 250 through on / off.

The power supply unit 210 can supply the DC power to the lighting device 200 by constantly supplying AC power through the third power supply line L3 and the second power supply line L2 and converting the AC power to the DC power.

The power supply unit 210 may supply the DC power to the MCU 220. The switch monitoring unit 250 determines whether or not the wall switch SW is on or off by determining whether or not the power supply is supplied through the closed loop formed by the first power supply line L1 and the fourth power supply line L4 can do.

3, the MCU 220 may include a power control unit 221, an alarm unit 222, a pattern correction unit 223, a status diagnosis unit 224, a storage unit 225, and a communication unit 226 have.

The power control unit 221 can control the supply of power required for operating the lighting apparatus 200 by using the power provided by the power supply unit 210. [ In particular, the power control unit 221 can supply power to the illumination unit 230 in response to the switch monitoring unit 250 determining that the wall switch SW is on. The illumination unit 230 can provide illumination in an installed space. The illumination unit 230 may include, for example, an LED illumination (not shown) and an LED driver (not shown). When the MCU 220 supplies power to the illumination unit 230, It is possible to convert the power source to a required power level and emit LED light. Alternatively, the power control unit 221 may interrupt the power supply to the lighting unit 230 in response to the switch monitoring unit 250 determining that the wall switch SW is off. The power control unit 221 can always supply power to the sensing unit 260 and the communication unit 240 without interruption. Here, the sensing unit 260 may be a smoke detection sensor. The sensing unit 260 may sense the smoke concentration to a degree of light collected after irradiating the room air.

The alarm unit 222 determines whether or not the smoke concentration detected through the sensing unit 260 exceeds a predetermined smoke concentration threshold value and if it is determined that the detected smoke concentration exceeds the predetermined smoke concentration threshold value, Visual alarms can be made at home. At this time, the alarm unit 222 can alert the home when the detected smoke concentration exceeds the predetermined number of times over a predetermined number of times (for example, 30 seconds) . The preset smoke concentration threshold may be 15%.

The alarm unit 222 may determine whether the smoke exceeding the smoke concentration threshold is a fire smoke or a life delay in a home alarm state, and may generate another generation alarm if it is determined that the smoke is a fire smoke. In the case of a third-generation alarm, a fire alarm message is sent to all the other households in the same building, and the other household lighting device receiving the fire alarm can fire a fire alarm. Alternatively, if it is determined that the smoke exceeding the smoke concentration threshold is a life delay, the alarm unit 222 can keep only the home alarm.

The alarm unit 222 can determine that the smoke exceeding the smoke concentration threshold corresponds to the life postponement if it corresponds to the pre-stored life smoke pattern. The pre-stored life pattern may be a smoke concentration increase rate for a predetermined period of time.

Referring to FIG. 4, it can be seen that the smoke concentration is increased gently compared to the smoke smoke. On the contrary, the smoke smoke initially rises very slowly compared to the life smoke, and the smoke temperature rises at a steep slope than the living smoke after a certain period of time. It can be seen that the rate of increase of the smoke concentration during the time (Δt in FIG. 4) before the predetermined time based on the point of time when the smoke concentration threshold is exceeded is much higher than that of the fire smoke. That is, the rate of increase of the smoke concentration during a predetermined time may be higher than that of the fire smoke.

In this regard, the alarm unit 222 can distinguish between fire smoke and fire smoke using the smoke concentration increase rate for a predetermined time. Here, the predetermined time may be a time period (? T,? T in FIG. 4, for example, 10 seconds) from a time point when the smoke concentration exceeds a predetermined smoke concentration threshold value to a predetermined time.

Referring to FIG. 5, a smoke concentration increase rate (in other words, a living smoke pattern) for a predetermined time period may be provided for determining a life delay. The pre-stored life smoke pattern may be set differently for each time zone. Here, the time zone may include a night time zone, a meal time zone, and a daily time zone. The life smoke pattern can be initially set at the initial value in the fire alarm system. As shown in FIG. 5, the rate of increase in smoke concentration over a predetermined period of time to correspond to a life delay in the middle of the night can be initialized to 0 to 2 [% / t], and during a predetermined time The rate of increase of the smoke concentration during the predetermined period of time may be initialized to 0 to 10% / t, . As will be described later, if the smoke concentration exceeds the predetermined smoke concentration threshold and it is determined as a fire smoke, but the smoke event is finally determined as the occurrence of the reset event, the threshold value of the smoke concentration for each predetermined time period may be updated. For example, when the smoke concentration threshold is exceeded, smoke smoke is recognized as shown in the following table.

slot The rate of increase in smoke concentration during Δt (lifetime smoke pattern) Judged as fire smoke Late night - 10 pm - 6 am 0 to 2 [% / t] When the smoke concentration increase rate during? T exceeds 2% meal - 6 am - 9 am
- 11:30 pm - 1:30 pm
- 5:30 pm to 7:30 pm 0 to 10 [% / t] When the smoke concentration increase rate during? T exceeds 10% daily life - 9:00 am to 11:30 pm - 1:10 pm to 5:30 pm
- 7:30 pm to 10:00 pm 0 to 5 [% / t] The smoke concentration increase rate during Δt exceeds 5%

That is, when it is not the living smoke pattern as compared with the living smoke pattern at the time zone exceeding the smoke concentration threshold, it can be determined as the fire smoke.

Referring again to FIG. 3, the alarm unit 222 determines whether a reset event is generated when it is determined that the user is delinquent while performing a home alarm, and may terminate the home alarm when it is determined that a reset event has occurred. Alternatively, if it is judged that the user is delayed while performing the home alarm, if the reset event does not occur, the home alarm can be maintained. The alarm unit 222 can determine that a reset event has occurred when there is a state change (transition from on to off or from off to on) between the on and off states of the wall switch SW during alarming. That is, the alarm unit 222 can determine whether a reset event has occurred by using the wall switch SW on / off monitoring result of the switch monitoring unit 250. To this end, the on / off monitoring result of the wall switch (SW) of the switch monitoring unit 250 may be provided to the alarm unit 222.

The alarm unit 222 may determine whether a reset event has occurred within a preset time (for example, ten minutes from the start of the home alarm) when the alarm is determined to be a fire smoke and another generation alarm is generated. At this time, if it is determined that the reset event has not occurred, the alarm unit 222 can maintain the home alarm. Alternatively, if it is determined that a reset event has occurred for a preset time, the home alarm can be terminated and the other household can be informed of the alarm end. The other household lighting device receiving the alarm end notification may terminate the alarm. The alarm unit 222 receives the reset event within a predetermined time during the generation of the alarm when it is judged to be the fire smoke, and the alarm unit 222 informs the user about the smoke related information (the predetermined time Δt)) can be shared with other generations. At this time, the smoke related information may be a rate of increase in smoke concentration (rate of increase in the concentration of living smoke) during a predetermined time (Δt) of the smoke causing the alarm. When the alarm unit 222 is determined to be a fire smoke and receives a reset event via the wall switch SW within a predetermined period of time while another generation alarm is being performed, the alarm can be finally determined as a life delay. Therefore, the rate of increase in smoke concentration over a predetermined time (Δt) of the smoke can be the rate of increase in the smoke concentration.

At this time, the pattern correcting unit 223 can update the pre-stored life smoke pattern using the smoke concentration increase rate for a predetermined time (DELTA t) of the smoke finally determined to be life postponement. As can be seen from the above, if the rate of increase of the smoke concentration over a preset time of the smoke exceeding the predetermined smoke concentration threshold exceeds the upper limit of the living smoke pattern, it can be determined as the fire smoke. Therefore, when the smoke concentration increase rate during the predetermined time (DELTA t) of the smoke finally determined to be the life delay exceeds the upper limit value of the living smoke pattern of the corresponding time zone on the existing living performance information table, the pattern correcting unit 223 It is possible to update the upper limit value of the living smoke pattern with the smoke concentration increasing rate during a predetermined time (DELTA t) of the smoke determined as the living smoke. Alternatively, if the smoke concentration increase rate during the predetermined time (DELTA t) of the smoke finally determined to be the life delay is less than the upper limit value of the living smoke pattern in the corresponding time zone on the existing life delay information table, The upper limit value of the smoke pattern can be maintained. Here, the updated life pattern may be a life pattern in a time zone in which the time when the smoke determined as the final life delay exceeds the smoke concentration threshold belongs.

Another generation sharing the smoke concentration increase rate for a predetermined time (DELTA t) of the smoke finally determined to be living life in the same manner is delayed for a predetermined time (DELTA t) of the smoke finally determined to be living life It is possible to update the preexisting living smoke pattern by the above-described method using the concentration increasing rate. By constantly updating the life-delay pattern in this manner, it is possible to minimize the non-recurrence of the street.

The state diagnosis unit 224 can evaluate the performance of the sensing unit 260. [ To this end, the state diagnostic unit 224 can collect the reference smoke concentration at the reference time from all households belonging to the same building. Here, the reference time is a predetermined time in the night time zone, and the reference smoke concentration may be the smoke concentration collected at the reference time. In order to collect smoke concentrations under the same environmental conditions in all households belonging to the same building, the reference time is preferably in the night time zone.

At this time, the state diagnosis unit 224 can evaluate the performance of the sensing unit 260 using the smoke concentrations collected from all the generations. Specifically, when the state diagnosis unit 224 determines that the sensed value of the smoke density collected from all the generations is lower than the average value of the smoke density, the sensing unit 260 may determine that there is an abnormality. At this time, the state diagnosis unit 224 can inform the outside that there is an abnormality in the sensor. Other generations can also evaluate the performance of the sensing unit of their generation in the same manner as above. In this way, the performance of the sensing part which is neglected even though it is installed for a long time can be evaluated every day.

As described above, the performance of the lighting apparatus can be self-diagnosed on the P2P network.

The storage unit 22 can store a life delay information table shown in Fig. 5 and a program necessary for the overall operation of the lighting apparatus.

The communication unit 240 can provide communication with a lighting apparatus of another generation through a communication network. A plurality of lighting apparatuses can establish a P2P network through a network formed by the communication unit 240. [

Hereinafter, a life pattern and a P2P-based smart fire alarm method according to a preferred embodiment of the present invention will be described with reference to FIGS. 1 to 6 attached hereto. 6 is a flowchart of a fire alarm method according to a preferred embodiment of the present invention. The preceding points are omitted or simplified. The configuration of the illumination device can be made more clear by the following matters.

First, the sensing unit 260 can sense the smoke concentration (S601).

At this time, the alarm unit 222 may determine whether the detected smoke concentration exceeds a predetermined smoke concentration threshold (S602).

If it is determined that the smoke concentration detected in S602 exceeds the predetermined smoke concentration threshold value, the alarm unit 222 may issue a home alarm (S603). In this case, the alarm unit 222 may alert the user when the detected smoke concentration exceeds a predetermined number of times. The predetermined smoke concentration threshold may be 15%.

Then, the alarm unit 222 can determine whether the smoke exceeding the smoke concentration threshold is a fire smoke or a life delay (S604). As described above, the alarm unit 202 can distinguish the fire smoke from the life smoke using the smoke concentration increase rate for a predetermined time. Here, the predetermined time may be a time from a point at which the smoke concentration exceeds the smoke concentration threshold to a predetermined time. And, the smoke concentration increase rate for a predetermined time may be higher than the fire smoke smoke life.

If it is determined in step S604 that the fire smoke is generated, the alarm unit 222 may generate another generation alarm (S605). If it is determined in step S604 that the alarm unit 222 is in the postponement of life, only the in-home alarm can be maintained. At this time, the alarm unit 222 may determine that the smoke exceeding the smoke concentration threshold corresponds to the life postponement if it corresponds to the pre-stored life smoke pattern. The pre-stored life pattern may be a smoke concentration increase rate for a predetermined period of time. The pre-stored living smoke pattern may be set differently for each time zone, and the time zone may include a night time zone, a meal time zone, and a daily time zone.

If it is determined in step S604 that smoke is to be generated, the alarm unit 222 may determine whether a reset event has occurred (step S610). If it is determined in S610 that a reset event has occurred, the alarm unit 222 may terminate the home alarm (S611). The alarm unit 222 can determine that a reset event has occurred when there is a state change (transition from on to off or from off to on) between the on and off states of the wall switch SW during alarming. That is, the alarm unit 222 can determine whether a reset event has occurred by using the wall switch SW on / off monitoring result of the switch monitoring unit 250. To this end, the on / off monitoring result of the wall switch (SW) of the switch monitoring unit 250 may be provided to the alarm unit 222.

Otherwise, in step S604, it is determined that the fire has been postponed, and the alarm unit 222 may determine whether a reset event has occurred within a predetermined time during another generation alarm (S606). If it is determined in step S606 that a reset event has not occurred within a predetermined time, the home alarm can be maintained.

Alternatively, if it is determined in S606 that a reset event has occurred within a predetermined time, the home alarm can be generated and alert notification to another household can be made (S607). As described above, when the fire event is detected and the reset event is received within a predetermined time while another generation alarm is being performed, the alarm unit 222 can finally determine that the fire smoke is a fire smoke. The alarm unit 222 may provide the smoke density increase rate for a predetermined time (DELTA t) of smoke determined as the final life delay to another household at the time of alarm end notification (S608). At this time, the pattern correcting unit 223 can update the preexisting living smoke pattern using the smoke concentration increasing rate for a predetermined time (DELTA t) of the smoke finally determined to be the living depletion (S609). As can be seen from the above, if the rate of increase of the smoke concentration over a preset time of the smoke exceeding the predetermined smoke concentration threshold exceeds the upper limit of the living smoke pattern, it can be determined as the fire smoke. Therefore, when the smoke concentration increase rate during the predetermined time (DELTA t) of the smoke finally determined to be the life delay exceeds the upper limit value of the living smoke pattern of the corresponding time zone on the existing living performance information table, the pattern correcting unit 223 It is possible to update the upper limit value of the living smoke pattern with the smoke concentration increasing rate during a predetermined time (DELTA t) of the smoke determined as the living smoke. Alternatively, if the smoke concentration increase rate during the predetermined time (DELTA t) of the smoke finally determined to be the life delay is less than the upper limit value of the living smoke pattern in the corresponding time zone on the existing life delay information table, The upper limit value of the smoke pattern can be maintained. Here, the updated life-style pattern may be a life-style pattern in a time zone in which the time at which the smoke determined as final life exceeds the predetermined smoke density threshold belongs. Another generation sharing the smoke concentration increase rate for a predetermined time (DELTA t) of the smoke finally determined to be living life in the same manner is delayed for a predetermined time (DELTA t) of the smoke finally determined to be living life It is possible to update the preexisting living smoke pattern by the above-described method using the concentration increasing rate.

Hereinafter, a method for diagnosing performance of a sensing unit in a lighting apparatus according to an exemplary embodiment of the present invention will be described with reference to FIGS. 1 to 4 and FIG. 7 is a flowchart illustrating a method of diagnosing performance of a sensing unit according to an exemplary embodiment of the present invention. The preceding points are omitted or simplified. The configuration of the illumination device can be made more clear by the following matters.

First, the state diagnosis unit 24 can collect the reference smoke concentration at the reference time from all households belonging to the same building (S71). Here, the reference time is a predetermined time in the night time zone, and the reference smoke concentration may be the smoke concentration collected at the reference time. In order to collect smoke concentrations under the same environmental conditions in all households belonging to the same building, the reference time is preferably in the night time zone.

At this time, the state diagnosis unit 24 can evaluate the performance of the sensing unit 21 using the reference smoke concentration collected from all the generations (S72). Specifically, when the state diagnosis unit 24 determines that the sensed value of the reference smoke concentration is lower than the average value of the reference smoke concentration collected from all the generations, it can determine that there is an abnormality in the sensor. At this time, the state diagnosis unit 24 can inform the outside that there is an abnormality in the sensor (S73, S74). Other generations can also evaluate the performance of the sensing unit of their generation in the same manner as above.

If it is determined in S73 that there is an abnormality, the state diagnosis section 24 can correct the sensitivity (S75). At this time, the state diagnosis unit 24 can raise the upper limit value of the living smoke pattern of the previously stored smoke information table by the smoke concentration obtained by subtracting the reference smoke concentration of the user from the average value of the reference smoke concentration collected from all the generations. At this time, the upper limit value of the living smoke pattern in all the time zones can be increased. Thereby, the decrease in sensitivity of the sensing unit 21 can be compensated.
