When the input module 1100 receives an input signal from the user, the input module 1100 transmits the input information to the controller 1200 of the beacon 1000 . The beacon 1000 operating in the normal mode is switched to the mesh mode by the user's input.

The control unit 1200 includes a WiFi registration unit 1210 , a normal mode operation unit 1220 , and a mesh mode operation unit 1230 to control the operation of the beacon 1000 . Meanwhile, the controller 1200 further includes a computing device (not shown) including one or more processors and one or more memories for controlling the beacon 1000 .

The WiFi registration unit 1210 performs a step of registering the beacon 1000 with the corresponding WiFi router 2000 .

The normal communication packet includes device identification information of the beacon 1000 and current mode information of the beacon 1000, that is, information that the beacon 1000 currently operates in a normal mode. It may further include packet information. The packet information includes the transmission/reception address of the corresponding communication packet, the type and form of the payload, and the like. In the normal mode, battery consumption can be minimized by setting the period of Tx to be long and the length of Rx to be short. On the other hand, the normal communication packet corresponds to a communication packet communicated in the BLE method.

The mesh mode operation unit 1230 causes the beacon 1000 to operate in a mesh mode in which a mesh communication packet is broadcast. The mesh mode corresponds to a mode in which the beacon 1000 operates when the beacon 1000 receives a user input or a mesh communication packet of another beacon 1000 is received. When the corresponding beacon 1000 receives a user input, the mesh communication packet includes device identification information of the corresponding beacon 1000 and mode information of the corresponding beacon 1000 .

A more detailed description of the normal mode and the mesh mode will be described later in the description of FIG. 3 .

3 schematically illustrates a transmission/reception period of a communication packet for each operation mode of the beacon 1000 according to an embodiment of the present invention.

As shown in FIG. 3 , the normal mode includes: a normal Tx mode in which a normal communication packet is broadcasted through the BLE communication module 1400 for a first time every first period; and a normal Rx mode for receiving a communication packet transmitted from the outside every first period through the BLE communication module 1400 for a second time period; During the WiFi communication module (1300) and the BLE communication module (1400) for broadcasting through the mesh Tx mode; and a mesh Rx mode for receiving a communication packet transmitted from the outside every second period through the WiFi communication module 1300 and the BLE communication module 1400 for a fourth time; including, wherein the mesh communication packet is the first a mesh communication packet and the second mesh communication packet, wherein the first period is longer than the second period, and the second period is shorter than the fourth period.

Schematically, Fig. 3 (a) shows the period of Tx and Rx in the normal mode, and Fig. 3 (b) shows the period of Tx and Rx in the mesh mode.

Specifically, as described above, the normal mode corresponds to a mode in which the beacon 1000 receives an input from a user or does not receive an external communication packet, and the mesh mode corresponds to a mode in which the beacon 1000 is not received. ) corresponds to the mode that operates when an input from the user is received or an external communication packet is received. As shown in FIG. 3 , the upper side of the time axis shows the Tx mode for transmitting a communication packet, and the lower side of the time axis shows the Rx mode for receiving the communication packet.

As shown in (a) of Figure 3, the beacon 1000 is a normal Tx mode for transmitting a normal communication packet in the normal mode; and a normal Rx mode for receiving a communication packet transmitted from the outside transmitted from the outside; operates alternately. As an embodiment of the present invention, it is preferable that the communication packet transmitted from the outside corresponds to a BLE communication packet communicated in the BLE method.

In the normal Tx mode, a normal communication packet is transmitted every first period, and one normal communication packet is transmitted for a first time. As an embodiment of the present invention, one normal communication packet may be transmitted once during the first time period, and as another embodiment of the present invention, one normal communication packet may be repeatedly transmitted during the first time period. have. In addition, the first period, preferably, may be set to 30 ms (milli-second) to 70 ms, more preferably, may be set to 40 ms to 60 ms, the first time is, preferably, It may be set to 300us (micro-second) to 400us, and more preferably, may be set to 350us to 390us.

On the other hand, in the normal Tx mode, a normal communication packet that can be received by the beacon 1000 and the adjacent beacon 1000 can be broadcast through the BLE communication module 1400 with reference to FIG. 2 . .

In the normal Rx mode, an external communication packet may be received for a second time in each of the first period. The second period may be preferably set to 40us to 80us, and more preferably, may be set to 50us to 70us. As an embodiment of the present invention, the first period, the first time period, and the second time period may be set through firmware according to an installation environment and purpose. In the normal mode, it is characterized in that the driving time of the normal Rx mode is shorter than that of the normal Tx mode. It is possible to exert the effect of maximizing the driving time. Since the beacon 1000 operating in the normal mode can serve as a connection node that receives notification information from another beacon 1000 that has received a user's input and delivers it to the control server 3000, at any time other beacon The normal Rx mode capable of receiving the communication packet transmitted by 1000 is essential.

Meanwhile, in the normal Rx mode, only a communication packet transmitted by the beacon 1000 and another beacon 1000 adjacent to the beacon 1000 in the BLE communication method may be received. In other words, in the normal Rx mode, with reference to FIG. 2 , a communication packet transmitted from the outside can be received only through the BLE communication module 1400 . At this time, when the beacon 1000 in the normal mode receives the normal communication packet transmitted by the other beacon 1000 in the normal Rx mode, the beacon 1000 operating in the normal mode receives the mode information included in the normal communication packet. By determining , it can continue to operate in the normal mode without switching to the mesh mode.

As shown in (b) of Figure 3, the beacon 1000 is a mesh Tx mode for transmitting a mesh communication packet in the mesh mode; and mesh Rx mode for receiving communication packets transmitted from the outside; As an embodiment of the present invention, preferably, the communication packet transmitted from the outside is a BLE communication packet communicated in a BLE manner; and a WiFi communication packet communicated in a Wi-Fi manner.

In the mesh Tx mode, a mesh communication packet is transmitted every second period. The mesh communication packet is a BLE communication packet for transmitting to another beacon (1000); and a WiFi communication packet for transmitting to the WiFi router 2000 interworking with the corresponding beacon 1000; and the beacon 1000 transmits the mesh communication packet for a third time. In the present invention, it is preferable to set the second period to be shorter than the above-mentioned first period, and through this, the mesh communication packet can be broadcasted faster in the mesh mode, and the communication packet transmitted from the outside is lower than that in the normal mode. It is possible to exert the effect of receiving everything quickly and accurately. In addition, as an embodiment of the present invention, the third time period may be the same time as the first time period, and as another embodiment of the present invention, it may be set longer than the first time period. The second period, the third time period, and the fourth time period may be set through firmware according to an installation environment and purpose. In addition, the mesh communication packet is broadcast using both the BLE communication module 1400 and the WiFi communication module 1300 with reference to FIG. 2 .

In the mesh Rx mode, a communication packet transmitted from the outside may be received every second period for a fourth time. Since the second period is shorter than the first period, it is possible to secure more resources for communication packet reception than in the normal mode. It is preferable that the fourth time is set longer than the second time of the normal Rx mode, and through this, the beacon 1000 operating in the mesh mode is more accurate than when in the normal mode and transmits the communication packet from the outside. , it can exhibit the effect of being able to receive quickly. In addition, the beacon 1000 operating in the mesh Rx mode, communication with other adjacent beacon (1000); and communication with the WiFi router 2000 that is interlocked; for this, both the BLE communication module 1400 and the WiFi communication module 1300 may be used.

Since the mesh mode consumes more power than the normal mode, it is driven only for a preset time.

In addition, the mesh mode operation unit 1230 may receive the normal communication packet and the mesh communication packet transmitted from the outside through the BLE communication module 1400 for a fourth time every second period, together with the mesh broadcasting step. The mesh receiving step is performed.

The mesh communication packet is an embodiment of the present invention, as shown in FIG. device identification information and mode information of the first beacon 1000.1, that is, information that the first beacon 1000.1 operates in a mesh mode, and may further include packet information of the mesh communication packet. . The packet information includes the transmission/reception address of the corresponding communication packet, the length of the corresponding communication packet, and the type and form of the payload.

Meanwhile, as another embodiment of the present invention, as shown in (b) of FIG. 10, in the case of the second beacon 1000.2 switched to the mesh mode by the mesh communication packet of the first beacon 1000.1, the first The first beacon 1000.1 includes a part of the mesh communication packet, and in detail, includes device identification information of the first beacon 1000.1, which is the beacon 1000 corresponding to the start node of the mesh network. Additionally, the mesh communication packet, like the normal communication packet described above, includes a transmission/reception address of the communication packet, the length of the communication packet, and the type and shape of the payload.

In addition, the first period is longer than the second period, and the second time period is shorter than the fourth time period. In other words, since the period of broadcasting the mesh communication packet in the mesh mode is shorter than the period of broadcasting the normal communication packet in the normal mode, more mesh communication packets can be broadcast in a limited time, and as a result, the first beacon ( When 1000.1) operates in the mesh mode, the second and third beacons 1000.3 located in the vicinity of the first beacon 1000.1 may receive the mesh communication packet of the first beacon 1000.1 more quickly and accurately. In addition, since the fourth time is set longer than the second time, it is possible to receive a communication packet transmitted from the outside more quickly and accurately in the mesh mode than in the normal mode.

Additionally, the beacon 1000 consumes more battery power when receiving a communication packet than when transmitting. Therefore, the beacon 1000 is built into the beacon 1000 by setting the second time to a minimum for the minimum power consumption in normal times, and to operate only for a preset time in the mesh mode, which consumes relatively large power. It is possible to maximize the running time of the old battery. As an embodiment of the present invention, the preset time is preferably set to 25 to 35 seconds.

As shown in FIG. 10 , the first beacon 1000.1 operating in the mesh mode performs a mesh connection request step of requesting a mesh connection to the second beacon 1000.2 operating in the normal mode. The mesh connection request step includes: transmitting a unique key of the first beacon 1000.1 to the second beacon 1000.2; receiving a verification result verified by the second beacon (1000.2) for the unique key; The first beacon 1000.1 receiving the verification result requests a mesh connection to the second beacon 1000.2, and disconnecting the connection with the second beacon 1000.2 before receiving a response thereto; The second beacon 1000.2 detects a disconnected connection with the beacon 1000 and switches from the normal mode to the mesh mode.

The mesh connection request step may be the same step as the mesh connection step of 1. Method for implementing a mesh network in a beacon system described above. That is, with reference to FIG. 4 , the mesh connection request step is performed through a process described below.

The first beacon 1000.1, which was operated in the normal mode, receives the user's input and is converted to the mesh mode. The first beacon 1000.1 switched to the mesh mode generates a first mesh communication packet by the mesh mode operation unit 1230 of the first beacon 1000.1 with reference to FIG. 9 (b), and BLE communication The first mesh communication packet is broadcast through the module 1400 . The normal mode operation unit 1220 of the second beacon 1000.2 may receive the first mesh communication packet broadcast by the first beacon 1000.1 by performing a normal receiving step, and the first mesh communication Upon receiving the packet, the second beacon 1000.2 generates a response signal for the first mesh communication packet and transmits it to the first beacon 1000.1.

Upon receiving the response signal, the first beacon 1000.1 transmits the unique key of the first beacon 1000.1 to the second beacon 1000.2. The second beacon 1000.2 verifies the received unique key, and transmits the verification result for the unique key to the first beacon 1000.1. Upon receiving the verification result, the first beacon 1000.1 requests a mesh connection from the second beacon 1000.2.

Thereafter, the first beacon 1000.1 performs a step of disconnecting from the second beacon 1000.2 after the mesh connection request, and the second beacon 1000.2 that has received the mesh connection request transmits the mesh connection request. An attempt is made to transmit a response corresponding to . At this time, as described above, since the first beacon 1000.1 has disconnected from the second beacon 1000.2, the response corresponding to the mesh connection request transmitted by the second beacon 1000.2 is the The first beacon 1000.1 cannot receive it, and the second beacon 1000.2 can recognize that the response with the first beacon 1000.1 is cut off, and based on the recognized result, the second beacon 1000.2 ) is converted to mesh mode.

The above-described mesh connection request step is characterized in that it is more simplified than the conventional Bluetooth pairing technology. In other words, in the conventional Bluetooth pairing technology, the first beacon 1000.1 does not cut the connection with the second beacon 1000.2, and the second beacon 1000.2 exchanges characteristics and data for a mesh connection. Further communication process is performed. However, in the mesh connection request step of the present invention, since it is not necessary to perform the above-described separate communication process, the mesh connection request step can be performed faster than the conventional Bluetooth pairing technology and consumes less power.

Specifically, as described above in the description of FIG. 8 , the beacon 1000 converted to the mesh mode by receiving the user's input is operated by the first mesh mode operation unit 1231 and the mesh transmitted from other beacons The beacon 1000 converted to the mesh mode by receiving the communication packet is operated by the second mesh mode operation unit 1232 .

As shown in (a) of FIG. 11 , when the user becomes in a dangerous situation, the user inputs an input to the first beacon 1000.1 through the input receiving unit of the first beacon 1000.1 that is installed or carried in a specific space. action can be performed. The first beacon 1000.1 receives the input information by the operation through the input module 1100.1 and transmits it to the first mesh mode operation unit 1231.1, and the first beacon 1000.1 receives the input information through the input module 1100.1. switch to mode.

That is, as an embodiment of the present invention, in (a) of FIG. 11, the first WiFi communication packet is a communication packet for communicating with the first WiFi router 2000.1, and the first BLE communication packet meshes the second beacon 1000.2. As a communication packet for switching mode, it may be simultaneously transmitted by the first mesh mode operation unit 1231.1.

As shown in (b) of Figure 11, the n-th beacon (1000.n) has received a mesh communication packet, more precisely, a BLE communication packet from another beacon located in the vicinity of the n-th beacon (1000.n). In this case, the BLE communication packet is transferred to the second mesh mode operation unit 1232.n of the n-th beacon 1000.n, and the second mesh mode operation unit 1232.n is the n-th mesh communication packet. is generated and transmitted to the WiFi communication module (1300.n) and the BLE communication module (1400.n) of the n-th beacon (1000.n) to simultaneously transmit the n-th mesh communication packet to the outside.

In other words, the second mesh mode operation unit 1232.n of the n-th beacon (1000.n) includes an n-th WiFi communication packet transmitted through the WiFi communication module 1300.n; And BLE communication module (1400.n) is broadcast through the n BLE communication packet; generates an n th mesh communication packet comprising a. 1 and 5 , the nth beacon 1000.n may simultaneously communicate with the nth WiFi router 2000.n and the (n+1)th beacon 1000.n+1. That is, as an embodiment of the present invention, in (b) of FIG. 11 , the nth WiFi communication packet is a communication packet for communicating with the n WiFi router 2000.n, and the nBLE communication packet is the (n+1)th It is a communication packet for converting the beacon (1000.n+1) to the mesh mode.

On the other hand, although Figure 11 (b) shows the process of receiving the BLE communication packet of another beacon and the location of the BLE communication module 1400.n separately for explanation, the BLE communication packet of the other beacon is the BLE communication module It is preferable to receive via (1400.n).

The safety bell system of the present invention is characterized in that it simultaneously performs BLE communication and Wi-Fi communication in one beacon 1000 . BLE communication can be performed with low power, but connection stability is poor, and Wi-Fi communication is connected to the gateway and wired to stably deliver the notification information of the safety bell to the control server 3000, but it must always receive power, The disadvantage is that the power consumption is relatively large. In order to compensate for these problems, the safety bell system of the present invention, as an embodiment of the present invention, distributes a plurality of beacons 1000 to each household in an area where single-person households are concentrated, and the plurality of The beacon 1000 may implement a mesh network through BLE communication. Each of the plurality of beacons 1000 can transmit notification information to the control server 3000 through the registered WiFi router 2000, so it can have high connection stability compared to the safety bell system using the BLE communication network, - It is possible to provide the user with a beacon 1000 having a longer driving time compared to the safety bell system using only the Fi method. Based on the above reasons, the beacon 1000 is a WiFi communication packet and generated by dividing the WiFi communication packet and the BLE communication packet in the first mesh mode operation unit 1231 and the second mesh mode operation unit 1232 and Each of the BLE communication packets is transmitted to the WiFi communication module 1300 and the BLE communication module 1400 and transmitted to the outside.

It works in mesh mode. The first beacon 1000.1 operating in the mesh mode transmits a first WiFi communication packet to the first WiFi router 2000.1 to which the first beacon 1000.1 is registered. However, the power of the first WiFi router 2000.1 is turned off or the connection state of the first beacon 1000.1 and the first WiFi router 2000.1 is unstable, so the first WiFi communication packet transmitted by the first beacon 1000.1 is not detected. The first WiFi router 2000.1 may not receive. In preparation for such a case, the first beacon 1000.1 broadcasts a first BLE communication packet, and a second beacon 1000.2 located in a position close to the first beacon 1000.1 receives the first BLE communication packet. can be converted to mesh mode.
