Description

[0001] The present invention relates to a method of setting a lighting environment based on a wireless autonomous relay for a group sensor,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0002] The present invention generally relates to a technology for smartly managing a group sensor installed with a plurality of sensor illumination lamps spread out in places such as a large parking lot, a performance hall and a large office.

More specifically, according to the present invention, when a system administrator manipulates a remote controller to change an illumination environment value for one sensor illumination lamp, the sensor illumination light autonomously relays the illumination environment information to a plurality of sensors And a group sensor for resetting the operating condition of the lighting lamp as a whole.

In this case, when various sensor lights are wirelessly transmitting different data at the same time in the process of wirelessly relaying the illumination environment information, the wireless transmission / reception is not performed due to data collision, The present invention relates to a technique for achieving wireless relay of illumination environment information stably without collision of wireless data.

Generally, a plurality of lighting lamps are widely spread out in places such as a parking lot, a performance hall, and a large office for user convenience. In order to provide a certain level of illumination as a whole without illuminating due to the nature of the place, in general, hundreds to thousands of LED lights are installed at regular intervals.

In this specification, the collective installation of a plurality of illumination lamps for a specific space is called a 'group illumination lamp'. There are three major ways in which these group lights operate.

The first is to always turn on multiple lights. In the traditional way, lighting design and maintenance management is simple and operation is still being adopted in most places. However, this method is disadvantageous in that it requires a lot of power to turn on the lighting lamp, and the maintenance cost is high because it is necessary to frequently replace the lamp because the life time of the lighting lamp is rapidly changed.

The second is to turn on / off or dimming multiple lights according to a certain pattern. For example, repeating the process of lighting a plurality of lights individually and randomly for a specific period of time, or repeating the process of brightening a little at a specific time interval. This method has the advantage of reducing the power consumption compared to the first method, and the LED light has started to be adopted with the spread of the light. However, this method is disadvantageous in that the user is not satisfied with the dark area formed intermittently and illumination control is performed irrespective of the situation.

The third is adaptive group control of multiple lights through computer control. To do this, a device identification number is assigned to a plurality of lighting fixtures, and their arrangement information is managed by a computer program, and illumination control is performed for each situation. Korean Patent No. 10-0956790 is an example of a third method. However, this method is very difficult to initialize because it is necessary to assign device identification numbers to thousands of light fixtures individually and manage their placement information. In addition, there is a disadvantage that the maintenance is complicated because the information must be input to a computer program every time a part of the illumination lamp is replaced.

Therefore, an idea to implement a group lighting with a sensor lighting instead of a general lighting has recently been proposed. That is, a plurality of sensors or the like are installed in a wide space, and lighting control is performed in accordance with whether or not a moving object is detected. In this specification, this is referred to as a 'group sensor or the like'.

Assuming that a group sensor is installed in a large indoor parking lot, a sensor lighting lamp disposed at a point when a person or a vehicle moves moves the lighting level temporarily to a bright level. When a person or vehicle leaves the point or completes parking, the lighting level drops again after a certain time. At this time, only the sensor lighting lamp detecting the movement can be illuminated brightly, but it is advantageous from the viewpoint of the safety and convenience of the user that the plurality of sensor lighting lamps within a certain distance from the sensing position, such as the driving direction or the parking area,

These group sensors are more economical in terms of initial installation cost than other existing methods, but they can reduce operation and maintenance costs greatly, and the user inconvenience is expected to be very low. In addition, since the sensor light is autonomously judged whether or not a moving object is present, control through a computer program is unnecessary, and accordingly initial installation is not so complicated. Furthermore, even if the sensor light is partially replaced, the maintenance is also very simple since no further work is required.

Accordingly, there is a need for a technology capable of effectively operating a group sensor constituted by arranging a plurality of sensor illumination lamps.

SUMMARY OF THE INVENTION An object of the present invention is to provide a technology for smartly managing a group sensor provided with a plurality of sensor illumination lamps spread widely in places such as a large parking lot, a performance hall, and a large office.

Particularly, it is an object of the present invention to provide a system and a method for controlling a plurality of sensor lamps, such as a group sensor or the like, And to provide a lighting environment setting technique based on a wireless autonomous relay for a group sensor or the like which totally resets the operating condition.

In particular, in the process of wirelessly relaying the illumination environment information, if different sensor lights transmit different data at the same time, wireless transmission and reception can not be performed due to data collision, and the object of the present invention is to provide a multi- The present invention provides a technique capable of stably achieving wireless relay of illumination environment information without collision of wireless data.

According to an aspect of the present invention, there is provided a method of setting an illumination environment for a group sensor including a plurality of sensor illumination lamps, wherein a sensor illumination lamp (hereinafter referred to as a remote sensor reception sensor) A first step of receiving a remote control signal for setting a lighting environment of a group sensor or the like from a remote control; A second step of acquiring illumination environment information for a group sensor or the like from a remote control signal by a remote control reception sensor or the like and generating an information relay packet by reflecting the illumination environment information; A third step in which a remote control reception sensor or the like wirelessly broadcasts an information relay packet in a first time slot; A fourth step of wirelessly receiving an information relay packet from at least one sensor illumination lamp among a plurality of sensor illumination lamps and setting the information relay packet as a relay sensor or the like; A fifth step of modifying a value of a specific field preset for the information relay packet transmitted or received by the remote control sensor and the relay sensor individually according to a preset update rule; A sixth step of separately wirelessly broadcasting the information relay packet modified by the remote control reception sensor and the relay sensor in the next time slot; A seventh step of judging whether or not the radio relay for the information relay packet is ended by referring to a value of a predetermined field of the information relay packet individually modified by the remote control sensor and the relay sensor; If it is determined that the wireless relay is not to be terminated, A ninth step of internally setting an illumination environment according to the illumination environment information acquired from the remote control signal by the remote control reception sensor or the like; And a tenth step of extracting the illumination environment information from the information relay packet received by the relay sensor individually and setting the illumination environment in accordance with the extracted illumination environment information. We propose a lighting environment setting method based on autonomous relay.

At this time, the information relay packet includes a packet count field for specifying a wireless relay limit of the illumination environment information. In the second step, the remote control sensor or the like initializes the packet count value of the information relay packet. In the seventh step, the reception sensor, the relay sensor, and the like individually reset or increase the packet count value in the unidirectional manner with respect to the self-transmitted or received information relay packet. In the seventh step, It is possible to judge whether or not the radio relay to the information relay packet is ended by comparing the packet count value of the information relay packet individually modified with the preset threshold value.

In the sixth step, the remote control reception sensor, the relay sensor, and the like are each equipped with the next time slot when a predetermined time period elapses from when the information relay packet is wirelessly broadcasted or wirelessly received from the outside Can be identified.

The information relay packet further includes a command code field for inputting a command code indicating a control operation of the illumination environment setting, and a data field for inputting a parameter value related to the command code. In the second step, The command code field and the data field of the information relay packet are set reflecting the illumination environment information, and in the tenth step, the relay sensor and the like can extract the illumination environment information from the command code field and the data field of the wirelessly received information relay packet have.

Meanwhile, the computer program according to the present invention is stored in a nonvolatile recording medium in order to execute a wireless environment-based lighting environment setting method for a group sensor or the like combined with hardware.

According to the present invention, there is an advantage that a group sensor provided with a plurality of sensor illumination lamps spread widely in a wide space can be conveniently managed.

Particularly, according to the present invention, even if the software for controlling the group sensor or the like is not installed, the system manager can set the illumination environment for one sensor illumination lamp with the remote controller, and a plurality of sensor illumination lamps can autonomously relay the illumination environment information to the wireless transmission / It is easy to initialize and manage the group sensor and the like.

Particularly, according to the present invention, there is an advantage that a plurality of sensor illumination lamps can autonomously operate without external control, and wireless relay of illumination environment information can be stably achieved without collision of wireless data.

The wireless autonomous group control technology such as a sensor according to the present invention can be preferably applied to an environment in which a plurality of illumination lamps are widely spread and installed for user convenience in a space such as a parking lot, a performance hall, and a large office. For convenience of description, the present invention will be described herein with reference to an example in which the present invention is applied to a parking lot illumination. However, the technique of the present invention can be preferably applied to an environment in which a large number of illumination lamps are installed, but is largely useless for most of the time, and occasionally, illumination is important only in some spots. The main lighting system is a typical example.

Hereinafter, the present invention will be described in detail with reference to the drawings.

FIG. 1 to FIG. 4 are diagrams conceptually showing an example in which a group sensor or the like according to the present invention is applied to a parking light. First, referring to FIG. 1, a plurality of sensor illumination lamps 100 are installed at a certain interval in the present invention on the ceiling wall of an indoor runner. The plurality of sensor illumination lamps 100 are provided to maintain the internal space of the indoor parking space at a predetermined brightness or higher. Generally, the sensor illumination lamps 100 are installed for the convenience of parking users, prevention of contact accidents, and prevention of crime.

And the vehicle 10 is slowly moving to park the vehicle in the parking lot or to remove the vehicle from the parking lot. In the present invention, in order to reduce power consumption, it is desirable to keep the lighting of the parking lot as low as possible, while illuminating the periphery of the moving vehicle 10 sufficiently brightly. At this time, it is not sufficient that the sensor illumination lamp (i.e., 101) sensing the automobile 10 provides illumination. In view of the fact that the vehicle 10 is running at a certain speed, the present invention is configured to illuminate the sensor light 102 (i.e.

In the present specification, an object satisfying a predetermined condition as an object for which the need for illumination is recognized is referred to as an " illuminated object ". For example, in the case of a parking lot, it is preferable that the moving vehicle or a person walking inside the car is set to be an object to be illuminated. On the other hand, it is preferable to set the parked vehicle so as not to correspond to the illuminated object. In the case of a performance hall, a person having a beacon terminal provided by the organizer can be designated as an illumination target object.

Each sensor illumination lamp 100 can detect the presence or absence of an object to be illuminated with respect to a certain region around itself by using a microwave sensor or the like. In the present specification, the corresponding region is called a sensing coverage 301. In addition, the area where each sensor illumination lamp 100 effectively illuminates is referred to as illumination coverage 302 in this specification. The sensing coverage 301 and the illumination coverage 302 may be set to correspond to each other or may be set separately.

On the other hand, the sensor illumination lamp 100 sensing the object to be illuminated is referred to as an object detection sensor 101 or the like in this specification. Referring to FIG. 1 to FIG. 4, a sensor or the like, which is an object to be illuminated, which is an object to be illuminated, enters the sensing coverage 301 of the object, becomes an object detection sensor 101 or the like. According to an embodiment, a plurality of sensors or the like can sense objects to be illuminated at the same time, as shown in FIG. 1 to FIG. 4. However, in this case, there are a plurality of object detection sensors 101 and the like.

In the present invention, not only does the object detecting sensor 101 or the like that senses the illumination object illuminate the illumination brightly. Sensors within a certain range around the object illuminate the light even though they do not sense the object to be illuminated. Called 'group control'. At this time, an area that is operated to brightly illuminate the periphery at the same time is referred to as a group coverage 303, and a sensor or the like that brightens the illumination at the same time around the periphery is referred to as a group synchronous sensor 102 or the like. Referring to FIG. 1 to FIG. 4, a certain range of group coverage 303 is formed around an object detection sensor 101, and a sensor or the like inside the object is a group synchronous sensor 102 or the like.

A sensor or the like which is far enough away from the object to be illuminated and does not belong to the group coverage 303 is called an external sensor 103 or the like.

As a result, in the present specification, a plurality of sensor illumination lamps 100 arranged in a specific area (for example, a parking lot) are divided into object detection sensors 101 and the like, group synchronous sensors 102 and the like, And an external sensor (103). Experience has shown that most cars in a parking lot are parked while a small number of moving cars 10 are common, so most of the sensors installed in a parking lot are classified as a group outside sensor 103. [

When the object to be illuminated moves, the designation of the object detection sensor 101, the group synchronous sensor 102 or the like is also changed in accordance with the object to be illuminated, as shown in [2] to [4] . Assuming that the situation of the parking lot is shown in order of time in FIG. 2 to FIG. 4, the area illuminated brightly corresponding to the process of parking the vehicle 10 downward and parking in a specific parking space, It can be confirmed that the robot 10 is moving while following the position of the robot 10.

In the present invention, in order to reduce power consumption, the lighting of the parking lot is generally kept low, and the periphery of the moving vehicle 10 is illuminated sufficiently brightly for user convenience and accident prevention. Accordingly, the group external sensor 103 or the like, which occupies most of the parking lot, sets the illumination levels of the object detection sensor 101, the group synchronous sensor 102, and the like to be high while keeping the illumination level low.

In FIG. 1 to FIG. 4, when the illumination level of the object detection sensor 101 and the group synchronous sensor 102 is set to 100% and the illumination level of the group external sensor 103 is set to 30% An example is shown. At this time, the numerical value of the specific illumination level can be set for each site according to the intention of the designer. In addition, the illumination levels of the object detection sensor 101 and the group synchronous sensor 102 may be set differently. In addition, when the group coverage 303 is set to a large value and the number of the group synchronous sensors 102 is large, the illumination level may be set to be higher the closer to the object detection sensor 101 or the like.

In the present invention, a technique for implementing group control among a plurality of sensor illumination lamps 100 will be described.

In the present invention, group control is implemented using wireless broadcast transmission / reception. The object detection sensor 101 or the like wirelessly broadcasts information indicating that the object to be illuminated is detected, that is, object detection information. Since the wireless signal is attenuated when the distance exceeds a certain distance and can not be effectively received, the group coverage 303 is naturally realized centering on the object detection sensor 101 and the like. That is, the wireless signal is based on a natural phenomenon in which the signal strength is gradually attenuated according to the transmission distance.

Since the object detection information is transmitted in a broadcast manner, the sensor illumination lamp 100 located within the group coverage 303 can receive the object detection information and operates as a group synchronous sensor 102 or the like. At this time, the group synchronous sensor 102 may be implemented only by wirelessly receiving the object detection information, or the group synchronous sensor 102 may be implemented only when the RSSI exceeds a predetermined threshold. Further, as described later, the additional criteria may be applied by management data such as a group ID (Group ID).

It is also possible to adjust the size of the group coverage 303. As an example, the object detection sensor 101 may adopt a method of adjusting transmission output when wirelessly transmitting object detection information. As another example, a method of adjusting the threshold of the signal reception strength (RSSI) to be the group synchronous sensor 102 or the like may be adopted. In all of these cases, in this specification, the object detection sensor 101 or the like describes that the object detection information is wirelessly broadcasted in the group coverage 303 at an output power to such an extent that other devices can effectively receive the object detection information.

Next, the present invention does not require a device that manages the group control as a whole, and as a result, the group control is achieved as the sensor illumination lamp 100 autonomously performs the predetermined operation. That is, the present invention performs lighting control by wireless autonomous group-control.

The sensor illumination lamp 100 continuously monitors whether or not an object to be illuminated exists in its own sensing coverage 301. When a specific sensor or the like senses the object to be illuminated as a result of the monitoring operation, the corresponding sensor or the like performs the role of the object detection sensor 101 or the like. The object detection sensor 101 or the like illuminates its own illumination coverage 302 and wirelessly broadcasts object detection information indicating that the object itself is sensed for group control to the surroundings.

As a result, the object detection sensor 101 periodically transmits the object detection information wirelessly while detecting the object to be illuminated, and stops transmitting the object detection information when the object to be illuminated disappears. A plurality of sensor illumination lights 101 and 102 existing within the group coverage 303 around the object detection sensor 101 and the like wirelessly receive the object detection information and they become a group synchronous sensor 102 or the like, Brightens the coverage 302. When the object to be illuminated moves, the illuminated area moves while following the object to be illuminated in real time.

5 is a block diagram showing a functional configuration of an individual sensor illumination lamp 100 constituting a group sensor or the like in the present invention, and FIG. 6 is a block diagram showing an example of a hardware configuration of the sensor illumination lamp 100 in the present invention. FIG. 5, the sensor illumination lamp 100 includes a moving object sensor unit 110, an illumination lamp emission unit 120, a wireless signal transmission unit 130, a wireless signal reception unit 140, an illumination level control unit 150 An illumination environment setting unit 160, an illumination environment relaying unit 170, and a remote control receiving unit 180.

First, the moving object sensor unit 110 monitors whether or not an object to be illuminated is present in its surroundings by using an ultrasonic sensor, an infrared sensor, a microwave sensor, or Bluetooth communication. The effective sensing range of the moving object sensor unit 110 becomes the sensing coverage 301 of the sensor illumination lamp 100 and the sensing coverage 301 is substantially predetermined due to the physical limitations of the sensor element. In FIG. 6, the moving object sensor unit 110 is implemented as a microwave sensor.

The illumination lamp light emitting unit 120 illuminates the surroundings using the light emitting device. At this time, an area that becomes substantially bright when the light emitting element illuminates the illumination becomes the illumination coverage 302 of the sensor illumination lamp 100. In FIG. 6, the illumination lamp emission unit 120 is implemented as a plurality of LED lamps.

The wireless signal transmission unit 130 transmits data wirelessly to exchange information between the sensor illumination lamps 100. [ First, when the moving object sensor 110 detects an object to be illuminated, the wireless signal transmitter 130 wirelessly transmits object detection information to its surroundings. The wireless signal is effectively received only within a certain region on its attribute, and is attenuated if it exceeds the range, so that effective reception is impossible. At this time, the area where the object detection information can be wirelessly received becomes the group coverage 303. In addition, the wireless signal transmitting unit 130 wirelessly transmits an information relay packet for informing the user of information that the lighting environment has changed, to the outside. In FIG. 6, the radio signal transmitting unit 130 is implemented with a 900 MHz RF module, an MCU, and an antenna.

The wireless signal receiving unit 140 wirelessly receives data, preferably object detection information and information relay packets wirelessly transmitted by the sensor light 100. When the object detection sensor 101 or the like 101 transmits the object detection information by wireless broadcasting, the group synchronous sensor 102 or the like existing in the group coverage 303 of the object detection sensor 101 or the like, And object detection information is wirelessly received. In addition, when the information relay packet is propagated to share the change information of the illumination environment, the sensor light 100 wirelessly receives the information relay packet through the wireless signal receiver 140. [ In FIG. 6, the radio signal receiving unit 140 is implemented by a 900 MHz RF module, an MCU, and an antenna.

The illumination level control unit 150 controls the illumination level of the sensor illumination light 100. The illumination level control unit 150 controls the illumination lamp emission unit 120 to set the illumination level to a high level since the illumination level control unit 150 detects the illumination target object 10 or receives the object detection information. Otherwise, the illumination level control unit 150 controls the illumination lamp emission unit 120 to set the illumination level to a low level. In FIG. 6, the illumination level controller 150 is implemented as an LED converter.

More specifically, when the illumination target object 10 is detected, the illumination level is set to a predetermined level A, and when the object detection information is received, the illumination level is set to the B level. Otherwise, Set the illumination level to C level. The relative relationship between these illumination levels is set so that the C level is lower than the A level and the B level (A level> C level, B level> C level). The relative relationship between the A level and the B level is preferably set to "A level > B level ". In FIGS. 1 to 4, an example is shown in which the A level and the B level are 100% and the C level is 30%. The illumination level control unit 150 may be set to be proportional to the RSSI of the object detection information. In this case, the group synchronous sensor 102 or the like near the object detection sensor 101 is relatively bright Lighting.

The illumination environment setting unit 160 sets an illumination environment that defines an operation environment of the group sensor and the individual sensor illumination lamp 100. For example, it is possible to set the values of the A level, B level, and C level, which are illumination levels in a situation. In addition, the size of the group coverage 303 can be set, which can be implemented in a manner that adjusts the radio transmission output or adjusts the threshold of the signal reception strength (RSSI). In addition, the attribute value of the internal components of the sensor illumination lamp 100 may be adjusted. In addition, a condition for determining whether or not the illumination target object 10 exists can be set. The object of the object to be detected is defined individually according to a specific environment (for example, a parking lot) to which the group sensor is applied. Therefore, a determination condition for detecting whether or not the illumination object is detected is set correspondingly.

The illumination environment relaying unit 170 propagates the illumination environment information through the wireless transmission / reception between the sensor illumination lamps 100. When the manager operates the remote controller to change the illumination environment value for one sensor illumination lamp 100, the illumination environment relay unit 170 wirelessly transmits the information to the surroundings. The sensor light of the surrounding area receiving the information wirelessly relays the light again to the surroundings. As the process is repeated a plurality of times, a plurality of sensor lights share the changed illumination environment information. The wireless relay of the illumination environment information will be described later in detail with reference to [FIG. 7] to [FIG. 11].

The remote control receiver 180 wirelessly receives a remote control signal from an external remote control 200 and obtains a change setting condition for the illumination environment. When the remote controller receiving unit 180 obtains the change setting condition from the remote control signal, the lighting environment setting unit 160 changes the lighting environment corresponding thereto and the lighting environment relaying unit 170 transmits the lighting environment information to another sensor lighting lamp 100). In FIG. 6, the remote control receiver 180 is implemented as an infrared (IR) LED device.

7 is a diagram illustrating a concept that a system administrator or installation engineer sets a lighting environment of a group sensor or the like in the present invention.

Since the installation environment of group sensor is different according to the application site and user's requirements are different, it is necessary to change the operation environment of group sensor such as lighting holding time of standby light, standby light level, wireless reception sensitivity, There is a need for means. For example, it is possible to adjust the convenience of the user and the power consumption of the lighting hold time and the standby lighting level, adjust the size of the group coverage to operate together when the object is sensed through the wireless reception sensitivity, And adjusts the size of the sensing coverage for detecting the object to be illuminated.

The technical means generally adopted in the field of electric and electronic for such a requirement is an infrared (IR) remote control. The user manipulates the buttons provided on the remote controller to adjust the settings for each device. However, it is very inefficient for a group sensor or the like to have a plurality of sensor illumination lamps 100 operate in the same operating environment, and a system administrator or installation engineer to set up several hundreds or thousands of sensor illumination lamps using an IR remote controller. Accordingly, the present invention adopts a method of wirelessly propagating the illumination environment information. That is, if the illumination environment value is changed for one sensor illumination lamp, the influence is transmitted to the remaining sensor illumination lamp. This allows the engineers to spend less time and effort in setting up the operating environment after installing the equipment such as the group sensor, that is, the plurality of sensor lights.

Referring to FIG. 7, when a system administrator or installation engineer manipulates the remote controller 200 to adjust the illumination environment of a sensor illumination lamp 122 through a remote control signal, autonomous wireless transmission / reception is performed among a plurality of sensor illumination lamps The corresponding information is propagated to the other sensor illumination lamps 121, 123 to 125, and 111 to 118. After a certain period of time passes through this process, the illumination environments of the sensor illumination lamps 111 to 118 and 121 to 125 constituting the group sensor and the like are entirely changed.

That is, when the installation engineer operates the remote controller 200, the sensor illumination lamp 122 near the sensor illumination lamp 122 receives the remote control signal. In the present specification, this is referred to as a " remote control reception sensor or the like ". The remote control reception sensor 122 etc. acquires the illumination environment value based on the remote control signal and propagates the illumination environment information to the other sensor illumination lamp 100 through wireless broadcast transmission / reception. Since there is a limitation in the output of the remote control sensor 122 or the like for transmitting the radio signal, the illumination environment information is relayed. The sensor illumination lamp 100 constituting the group sensor or the like changes and sets its own illumination environment according to the illumination environment information directly received by the remote controller or relayed.

FIG. 8 is a diagram illustrating a concept that information relay packets are sequentially propagated in order to set an illumination environment of a group sensor or the like in the present invention. FIG. (100) according to an embodiment of the present invention.

As described above, when the installation engineer operates the remote controller 200 to set the lighting environment, the lighting environment information is wirelessly relayed from the remote control receiving sensor 122 to other sensor lighting lamps and propagated. However, due to the nature of wireless transmission / reception, when packets containing different data are transmitted at the same time, the receiving side can not normally receive data due to mutual interference of these packets.

Referring to FIG. 7, at first, the remote control reception sensor 122 alone transmits the illumination environment information wirelessly. However, when entering the relaying of the illumination environment information, a plurality of sensor illumination lights wirelessly transmit the illumination environment information simultaneously . In the present invention, since the sensor illumination lamp is configured to operate autonomously, the illumination environment information is autonomously wirelessly transmitted without being controlled by anyone. At this time, when a plurality of sensor illumination lamps arranged close to each other transmit a different packet to the effect that wireless relaying is performed, an error occurs on the receiving side and the wireless relay is stopped at this point.

On the other hand, if the modulation / demodulation module is mounted on the sensor illumination lamp 100, there is no problem even if different sensor lights are simultaneously transmitting different packets. However, this is not a very desirable approach in the field of lighting because it involves significant cost increases. Accordingly, in the present invention, a plurality of sensor illumination lamps 100 autonomously transmit the same packet data at the same time while wirelessly relaying information relay packets containing illumination environment information. The contents shown in the following [FIG. 8] to [FIG. 11] are elaborarily derived in order to achieve this object.

First, referring to FIG. 8 (a), in the first time slot (t =? T), the remote control reception sensor (L1) wirelessly broadcasts the information relay packet P1 to its surroundings. In this specification, an information relay packet transmitted and received in the k-th time slot is referred to as 'Pk' for the sake of convenience. Two sensor illumination lamps L2 and L3 disposed around the remote control sensor L1 and the like receive the information relay packet P1 wirelessly. As shown in Fig. 9, these two sensor illumination lamps L2 and L3 are referred to as a 'primary relay sensor or the like'.

Referring to (b) of FIG. 8, in the second time slot (t = 2? T), the remote control reception sensor L1 and the primary relay sensor L2, To the wireless terminal. The remote control receiver L1 and the primary relay sensors L2 and L3 mutually receive the information relay packets P2 to be wirelessly transmitted to each other and the four relay sensors L2 and L3 disposed around the primary relay sensors L2 and L3 The sensor light lamps L4 to L7 additionally receive the information relay packet P2. As shown in Fig. 9, these four sensor illumination lights L4 to L7 are referred to as a 'secondary relay sensor or the like'. At this time, it is important that the remote control reception sensor (L1) and the primary relay sensor (L2, L3) are configured to wirelessly transmit the same information relay packet P2 in order to prevent data interference on the reception side. For example, the sensor light L6 receives information relay packets from both of the first and second primary relay sensors L2 and L3. Since they are the same packet P2, they can normally receive data without interference.

Referring to (c) of FIG. 8, in the third time slot (t = 3? T), the remote control reception sensor L1 and the primary and secondary relay sensors L2- And transmits the relay packet P3 by wireless broadcast. The remote control reception sensor L1 and the primary and secondary relay sensors L2 to L7 mutually receive the information relay packets P3 to be wirelessly transmitted to each other and are arranged around the secondary relay sensors L4 to L7 The three sensor illumination lights L8 to L10 further receive the information relay packet P3. As shown in Fig. 9, these three sensor illumination lamps L8 to L10 become a 'third-order relay sensor or the like'. At this time, it is important that the remote control reception sensor (L1) and the primary and secondary relay sensors (L2 to L7) are configured to wirelessly transmit the same information relay packet P3 in order to prevent data interference on the reception side. For example, the sensor light L9 receives information relay packets from the two secondary relay sensors L4 and L7, and since they are the same packet P3, data can be normally received without data interference.

As the time slot elapses one by one, the illumination environment information is gradually radiated from the remote control reception sensor (L1) on the information relay packet. If the processes of (a) to (c) of FIG. 8 are repeated a plurality of times, the illumination environment information will propagate to all or at least a very wide area such as a group sensor.

10 is a diagram showing an example of a field format of an information relay packet used for propagating illumination environment information in the present invention. As described above with reference to FIGS. 8 and 9, the sensor illumination lamp 100 periodically and repeatedly transmits the information relay packet to propagate the illumination environment information to the group sensor or the like. FIG. 10 shows a case where the period T is 5 msec. In this case, one period for transmitting the information relay packet is called a 'time slot', and the total number (threshold) for repeatedly transmitting the information relay packet is set in advance by a designer such as a group sensor in consideration of the size of the installation site : 100 times).

A plurality of sensor illumination lamps 100 constituting a group sensor or the like must share a time slot formed at intervals of 5 msec. To this end, multiple sensor illumination lamps 100 may be configured to have a synchronized clock module, but it may be possible to share a timeslot even without a synchronized clock module. The remote sensor receiver (L1) repeatedly transmits the information relay packet by a threshold value at intervals of 5 msec. When the relay sensor (L2 to L10) receives the information relay packet, the received relay relay packet When it is configured to repeatedly transmit, a time slot-shared effect is obtained. The number of times the relay sensor (L2 to L10) repeatedly transmits the information relay packet is determined according to the packet count field value described later.

The field configuration of the information relay packet includes a group ID (4 bytes), a device ID (4 bytes), a packet count (2 bytes), a group number (2 bytes) (Command Code, 2 Bytes), and data (Data, 2 Bytes).

First, a group ID field is a value for distinguishing one group sensor or the like from another group sensor or the like. For example, in the case of parking light, different buildings may be assigned different group identifiers. Further, for a multi-storey car park, a different group identifier may be assigned to each floor. Since it is difficult to designate the boundary of the reception object, it is preferable to divide the boundaries of the group sensor and the like by applying a group identifier in order to supplement the wireless signal.

The Device ID field indicates who the sensor light is for transmitting the information relay packet. In the examples of Figs. 8 and 9, the device unique number values of the remote control reception sensors L1 and the like are set in the device identifier (Device ID) field in the series of information relay packets P1, P2, and P3.

The Packet Counter field indicates how many times the corresponding information relay packet has been repeatedly transmitted so as to limit the number of times the light environment information is wirelessly relayed to the space limit. The packet count (PC) field is implemented to increment or decrement in a unidirectional manner every time a time slot is crossed. In the present specification, it is assumed that the packet count (PC) field is incremented by one for convenience.

The PC field value is set to 1 when the remote control reception sensor (L1) first transmits the information relay packet, and the previous PC field value is incremented by 1 when the relay sensor (L1 to L10) do. In this case, in the example of Fig. 8, the PC field value of the information relay packet Pk is k. When the value of the packet count field reaches a predetermined threshold value, the relay transmission ends. Accordingly, the remote control reception sensor (L1) repeatedly transmits the information relay packet by the threshold value. The relay sensor (L1 to L10) repeatedly transmits the information relay packet by the difference between the PC field value and the threshold value of the information relay packet received by itself.

On the other hand, a spatial boundary in which the illumination environment information is propagated is set by the threshold value applied to the packet count field. For example, if the wireless transmission distance is 3 meters and the threshold is set to 100, the illumination environment information is propagated to a distance of about 300 meters from the remote control reception sensor (L1).

The Group Number field is a field allocated for the purpose of turning on and off all the LED lights of the group sensor or the like and is not related to the present invention.

The command code field is used to identify the control operation of the illumination configuration to be achieved through the information relay packet. In the present invention, The set command code will be input.

The Data field is a field for inputting a parameter value related to the instruction code.

11 is a diagram conceptually showing a change in a field value of an information relay packet, in particular, a value of a packet count field, in a radio relay process of illumination environment information according to the present invention.

11, a lamp L1 is a sensor lamp for receiving a remote control signal and wirelessly transmitting an information relay packet for the first time, that is, a remote control sensor or the like, and the other lamps L2 to L10 are sensor lights for relaying the information relay packet after receiving the relay packet, k-th relay sensor. In FIG. 11, the threshold of the number of repetitive transmissions is represented by n, where k is a natural number from 1 to a threshold value (n).

As the user operates the remote controller 200, the time slot starts from the instant when the remote control reception sensor L1 or the like sets the illumination environment.

The packet count (PC) field of the information relay packet is set to 1 in the first time slot, and thereafter is set to the information relay packet with a value incremented by 1 each time the time slot advances one by one. The remote control sensor L1 etc. sets the PC field to 1 to transmit the information relay packet and the relay sensors L2 to L10 increase the PC field value contained in the information relay packet received by itself to 1 And transmits an information relay packet.

Since air quality is continuously changed, the reliability of wireless communication is very low, which may result in failure to receive information relay packets normally. However, even if such an error situation occurs, since the information relay packet is repeatedly transmitted the number of times specified by the threshold value, the reliability that the illumination environment information can be normally propagated is sufficiently secured. At this time, the relay sensors (L1 to L10) can identify the order number of the information relay packet currently received from the PC field value, and thereby identify how many times the information relay packet needs to be repeatedly transmitted.

Referring to FIG. 11, an operation performed by each of the plurality of sensor illumination lights L1 to L10 will be described. These sensor lighting lights L1 to L10 do not perform this operation under the control of somebody but operate autonomously.

First, the remote control reception sensor (L1) receives the remote control signal and acquires the illumination environment information based thereon. The remote control reception sensor L1 or the like constitutes the information relay packet P1 by reflecting the illumination environment information and wirelessly transmits the information relay packet P1 to the outside in the time slot 1. [ At this time, the PC field of the information relay packet P1 is set to "1". The remote control reception sensor (L1) repeatedly transmits a total of n times information relay packets while incrementing the PC field value from P1 to Pn by 1 every time the time slot advances at 5 msec intervals, for example.

The primary relay sensors L2 and L3 receive the information relay packet P1 in the time slot 1 and set their own lighting environment according to the internal field value. Then, every time the time slot is advanced, the PC repeats the transmission of the information relay packet P1 by a total of (n-1) times from P2 to Pn while incrementing the PC field value by 1.

The secondary relay sensors (L4 to L7) receive the information relay packet P2 in the time slot 2 and set their own lighting environment according to the internal field value. The sensor light L6 simultaneously receives the information relay packets transmitted by the plurality of primary relay sensors or the like, but the interference value does not occur because the data values are the same. Then, every time the time slot advances, it repeatedly transmits (n-2) times from P3 to Pn while incrementing the PC field value by 1 for the information relay packet P2 received.

The tertiary relay sensors L8 to L10 receive the information relay packet P3 in the time slot 3 and set their own lighting environment according to the internal field value. The sensor light L9 simultaneously receives information relay packets transmitted by a plurality of secondary relay sensors or the like, but the interference value does not occur because the data values are the same. Then, every time the time slot advances, it repeatedly transmits (n-3) times from P4 to Pn while incrementing the PC field value by 1 for the information relay packet P3 received.

This process is performed until the packet count (PC) field value of the information relay packet reaches the threshold value n. That is, the information relay packet, which is repeatedly transmitted by itself, is not transmitted by radio, and the sensor light receiving the information relay packet Pn whose PC field value is set to the threshold value (n) does not relay the packet.

12 is a flowchart illustrating an overall process of a lighting environment setting method based on a wireless autonomous relay for a group sensor and the like according to the present invention. 12 is a flow chart illustrating the operation of the remote controller 200 for adjusting the lighting environment, such as the illumination holding time of the sensor illumination, the illumination level of the standby state, the wireless reception sensitivity, the object detection signal distance, etc., And the illumination environment information is propagated when it is manipulated.

Step S100: First, among the plurality of sensor illumination lamps, a sensor illumination lamp close to the remote controller 200, that is, a remote controller reception sensor L1 receives a remote control signal for setting the illumination environment of the group sensor or the like from the remote controller 200 .

Preferably, the plurality of sensor illumination lamps 100 constituting the group sensor or the like may be a remote control reception sensor or the like. When the user operates the remote control 200, the sensor illumination lamp 100, which is positioned close to the remote control 200, (L1) becomes a remote control reception sensor or the like. In another embodiment, a sensor illumination lamp to serve as a remote control sensor may be provided in advance.

Step S110: The remote control sensor L1 or the like obtains the illumination environment information for the group sensor or the like from the received remote control signal. That is, based on the remote control signal, information on how the lighting operation of the group sensor or the like should be set or how it should be changed, that is, the illumination environment information is obtained.

Then, the remote control reception sensor (L1) generates an information relay packet by reflecting the acquired illumination environment information. Referring to FIG. 10, the information relay packet includes a group identifier field, a device identifier field, a packet count field, a group number field, a command code field, and a data field. Of these, the packet count field is for specifying a wireless relay limit of the illumination environment information, the command code field is for inputting a command code indicating the control operation of the illumination environment setting, and the data field is for inputting a parameter value related to the command code .

In step S110, the remote control receiver sensor L1 initializes the packet count value of the information relay packet, and the command code field and the data field set the value according to the preset encoding rule reflecting the illumination environment information. The information relay packet generated in step S110 is indicated as P1 in [FIG. 8] to [FIG. 11].

Step S120: The remote control reception sensor (L1) wirelessly broadcasts the information relay packet P1 to its surroundings in the first time slot.

At step S130, at least one sensor illumination light among the plurality of sensor illumination lights 100 constituting the group sensor wirelessly receives the information relay packet, and the sensor illumination light, which wirelessly receives the information relay packet, And a relay sensor to participate in the wireless relay process of the relay packet.

8 and 9, the information relay packet P1 transmitted by the remote control sensor L1 and the like is transmitted to the two sensor illumination lamps L2 and L3 disposed around the remote control sensor L1, This wireless reception. These sensor lights L2 and L3 become relay sensors or the like, and wirelessly broadcast the information relay packets in the subsequent time slots.

The sensor light receiving the information relay packet transmitted by the other relay sensor or the like wireless broadcast also sets itself as the relay sensor and transmits the information relay packet by wireless broadcast in the subsequent time slot. The secondary relay sensors (L4 to L7) and the tertiary relay sensors (L8 to L10) shown in (b) and (c) of FIG.

Step S140: The remote control reception sensor L1 and the relay sensors L2 to L10 respectively transmit a specific field set in advance for the next time slot, In the above-described embodiment, the value of the packet count field is modified according to a preset update rule.

The remote control reception sensor (L1) corrects the packet count value for the information relay packet generated and transmitted by itself. For example, at the second time slot (t = 2? T), the primary relay sensor (L2, L3) that has transmitted the information relay packet corrects the packet count value for the information relay packet transmitted by itself . The secondary relay sensor (L4 to L7) at the second time slot (t = 2? T), for example, a relay sensor newly receiving the information relay packet and set to the relay sensor or the like, Modify the value.

At this time, as the update rule of the packet count field, a method of resetting the packet count value in a unidirectional manner is preferable. This is for setting a limit on the number of radio relaying of information relay packets and space. In the present specification, it is assumed that it increases by 1 for convenience.

Step S150: The remote control reception sensor L1 and the relay sensors L2 to L10 wirelessly broadcast the information relay packet whose packet count field is modified as described above, individually in the next time slot.

In the present invention, since a plurality of sensor illumination lamps 100 are assumed to operate autonomously, it is separately performed in step S150 to identify the next time slot. To this end, the remote control reception sensor L1 and the relay sensors L2 to L10 individually transmit the information relay packet at a time point when wireless broadcast transmission of the information relay packet is performed or a predetermined time period (for example, 5 msec ) Elapses, it is possible to identify that the next time slot has arrived.

At this time, if the remote control reception sensor (L1) and the relay sensor (L2 to L10) are identified as the next time slot, the individually modified wireless relay broadcast packets are transmitted.

Step S160: The remote control sensor L1 and the relay sensors L2 to L10 refer to the packet count value of the information relay packet individually modified and continue radio relay for the information relay packet or end . Preferably, the packet count value is compared with a preset threshold value. In the example in which the update rule of the packet count field increases unidirectionally, it can be determined that the wireless relay is terminated when the packet count reaches a specific value, for example, 100. In the example in which the update rule of the packet count field is unidirectionally reduced, it can be determined that the wireless relay is ended when the packet count becomes a specific value, for example, 0 or less.

Step S170: If it is determined in step S170 that the wireless relay is not terminated, the flow advances to step S130 to update the information relay packet and wireless broadcast transmission according to the progress of the time slot.

Step S180: The illumination environment is internally set in accordance with the illumination environment information acquired from the remote control signal by the remote control sensor or the like. This process may be performed after the wireless relay process of the illumination environment information is terminated or may be performed immediately after receiving the remote control signal, that is, immediately after step S100.

Step S180: The relay sensors L2 and L10 individually extract the illumination environment information from the information relay packet received by radio and internally set the illumination environment according to the extracted illumination environment information. At this time, the relay sensor (L2 to L10) parses the information relay packet received by itself, identifies the value of the command code field and the data field, and extracts the illumination environment information from the combination. This process may be performed after the wireless relay process of the illumination environment information ends or may be performed as soon as the relay sensors L2 to L10 receive the respective information relay packets.

Meanwhile, the present invention can be embodied in the form of computer readable code on a computer-readable non-volatile recording medium. There are various types of storage devices such as a hard disk, an SSD, a CD-ROM, a NAS, a magnetic tape, a web disk, a cloud disk, and the like.
