Description

Technical Field [0001] The present invention relates to a wireless communication system and a communication method using the wireless communication system,

The present invention relates to a smart phone, a mobile phone, a PHS telephone, a tablet, a personal digital assistant (PDA), a personal digital assistant and a communication method using the system. The present invention relates to a wireless communication system and a communication method using the system.

Conventionally, when a lighting apparatus or the like is operated by a portable terminal device, a pairing setting operation is performed by a Bluetooth specific address and a password code at the time of connection setting, in order to maintain high security between Bluetooth devices.

The following is an example of the communication establishing method in the case where the portable terminal apparatus is connected to the lighting apparatus by communication and the on / off control of dimming, coloring, and illumination of the lighting apparatus is performed. On the other hand, in the following description, when the portable terminal apparatus and the Bluetooth controller (BT controller) of the lighting apparatus have a main relationship, they may be referred to as a master apparatus and a slave apparatus, respectively.

9 is a view showing a conventional example of a communication system in which a plurality of operating terminals can control the LED lighting apparatus.

The operating terminals A, B and X are smart phones each equipped with Bluetooth. The LED lighting apparatus is also equipped with Bluetooth, and can be connected to the operation terminals A, B, and X by Bluetooth communication (BT communication).

Since the Bluetooth communication is a one-to-one connection, when the operating terminal A is connected to the LED lighting apparatus, the other operating terminals can not be connected to the LED lighting apparatus.

This communication method is not advantageous in that any operating terminal can operate the LED lighting apparatuses because it does not provide security, and a person other than the owner of the LED lighting apparatus, for example, a malicious third party Even if the terminal X is owned, there is a problem in terms of safety because the LED lighting apparatus can be operated.

10 is a diagram showing another example of a conventional communication system in which a plurality of operation terminals can control an LED lighting apparatus considering safety.

The LED lighting apparatus is a communication system that can exclusively connect to the LED lighting apparatus by pairing the operation terminal A and the terminal C as well. For the LED lighting fixture, there is a PIN code for connection, and it is necessary to input the PIN code for pairing.

The PIN code is a key obtained only by the person who owns the LED lighting fixture when the user obtains the LED lighting fixture and obtains the encryption key or the LED lighting fixture attached to the LED lighting fixture itself, to be.

Accordingly, when the LED lighting apparatus is connected by the operating terminal A, for example, when the PIN code is '1234', the operating terminal A performs a key operation to input a PIN code. The operation terminal C is also a terminal that can be set to be connectable to the LED lighting device by pairing, but it can not be connected by inputting another PIN code, for example, '0000'. A malicious third party can not access the LED lighting fixture unless it obtains a valid PIN code.

However, in such a communication establishing method, the PIN code must be input to the operating terminal by key operation or the like, so that there is a problem that the operation becomes troublesome at the time of communication establishment. Generally, the PIN code has a lot of digits in order to improve the security, and the pairing is troublesome.

11 is a view showing another example of a conventional communication system in which a plurality of operating terminals can control an LED lighting apparatus which takes safety into consideration and which does not make the pairing operation complicated.

The LED lighting apparatus stores a PDA (unique device address) registered in advance in the LED lighting apparatus or transmitted at the time of pairing as a registration list.

The operating terminal A is a type that transmits a PDA, and transmits a PDA by itself when pairing, and the LED lighting device puts the transmitted PDA on the registered list.

With this communication establishing method, only the operating terminal registered in the LED lighting apparatus can exclusively connect to the lighting apparatus with respect to the other operating terminals.

Only an operating terminal equipped with a Bluetooth-specific PDA is connected to the LED lighting apparatus at the next connection.

On the other hand, the operation terminal of the type that transmits RDA (random device address) can not connect to the LED lighting device because the address stored at the time of pairing and the address at the time of reconnection are different. That is, since the RDA transmission type operating terminal transmits an arbitrary address every time it connects, it does not coincide with the address written in the registration list of the LED lighting fixture and can not be connected.

In some smartphones, even if a PDA is used as described above, it can not be read by software installed in a smart phone. Further, a BD address to be transmitted in Bluetooth communication is arbitrarily sent, and the above communication establishment method It can not be connected to the LED lighting fixture.

This control is believed to avoid the risk of direct access to the smartphone from outside.

When pairing with a high degree of security is performed, a method of communicating with each other using a unique Bluetooth address and a password code is adopted. Among the smart phones, Bluetooth built-in PDA 'is not used in Bluetooth communication, Not set ', and an arbitrary address is transmitted for each connection. For this reason, there is a problem that high-security connection using such a PDA can not be performed.

Patent Document 2: JP-A-2005-217646

Patent Document 3: JP-A-2012-532404

As described above, the slave device to be controlled with Bluetooth is a peripheral device such as a mouse, a keyboard, a printer and the like for audio equipment, a digital camera, a headset and a stereo for AV equipment, Lt; / RTI >

A system has been proposed in which this is controlled by a master device that is a portable terminal device by Bluetooth communication.

In Patent Document 1, the control target is a plurality of air conditioners, and the near-field radio waves from the portable telephone are received by the near-field radio wave transmitting and receiving unit of the air conditioner controller installed in the air conditioner to control temperature, air volume and on-off control of each air conditioner.

 When the unique device number specifying the owner is transmitted from the cellular phone to the air conditioner controller, it is checked whether or not such a device number is included in an identification number (device number) group registered in advance, It is determined that the terminal is an authorized terminal, and configuration data from the portable telephone is accepted.

It is possible to control the target air conditioner in view of matching of the device numbers and accepting access from the portable telephone. However, by transmitting the same device number to other portable telephone terminals, there is a possibility that the air conditioner is controlled even if the third party does not use the portable telephone terminal corresponding to the air conditioner. Security is not sufficient even with device numbers. Also, there is no disclosure to increase security by pairing using a special communication establishment method.

Patent Document 2 makes it possible to perform authentication and pairing between wireless communication apparatuses without requiring a difficult operation and to perform communication using a wireless communication apparatus with high security strength. By performing short-range wireless communication, When a client device (portable terminal or the like) located at a certain distance from the host device (slave device to be controlled) is found, the host device generates an authentication code by random number generation, sets an access right to the authentication code, The authentication code is stored in association with each other, and the generated authentication code is transmitted to the client device and stored in the client device. So that the host device and the client device can be paired without a complicated operation by the user.

Such a wireless communication apparatus generates an authentication code when the host apparatus enters the client apparatus within the short-range wireless communication distance. It is not necessary to perform an operation of inputting an authentication code at the client device side when pairing.

However, when the host device and the client device are not close to each other or when the additional client device is not close to the host, pairing can not be performed. For example, after attaching the host device to the ceiling, additional client devices can not pair because a new client device can not approach a certain distance even if it tries to pair.

Patent Document 3 is a system that controls an illumination network and manages the interaction with the illumination network. Determine the appropriate level of interactivity with the controllable lighting network and system, exercise control over the access of the system to the user information, exercise control over the reaction of the system to the presence of the user, will be. The mobile device has a processor and a memory in addition to the controllable lighting network and is configured to link the processor to the mobile device and the mobile device selects the interactivity level (off, ignore, personal, notify, adjust) . For example, an IPHONE (registered trademark) device can be applied as a personal device (personal mobile electronic communication device) carried by a user.

This means that a smartphone can be used to transmit and output arbitrarily. Such a system does not start establishing pairing in the Bluetooth communication and exclusively performing communication on a one-to-one basis.

A plurality of portable terminal apparatuses 1 can be prepared. The service area (communication coverage area) is a distance of 10 m or 100 m from the standard under open environment. However, the operable distance at a position that is not under the open environment in which the LED lighting apparatus 20 can be seen is shorter than the open distance.

The portable terminal apparatus 1 is provided with a circuit section (not shown) for realizing functions inherent to the portable terminal device such as communication, data transmission and reception, camera function, etc., as well as a circuit section for realizing the wireless communication according to the present invention (See Fig. 2).

After the LED lighting fixture 20 is installed, the power is turned on to operate the LED lighting fixture. Thus, the LED lighting apparatus 20 is initialized to be ready for wireless communication, and enters the standby mode (see FIG. 5). In this state, the BT controller 22 (see FIG. 3) first sends out a PDA (Bluetooth unique device address) and D / N (device name) of its own to the outside (referred to as mode N).

In this mode N, when a pairing request (see FIG. 4) is made from the microcomputer of the LED lighting apparatus 20 by an external switch (remote control operation or pullless operation), the mode P is entered. Here, the remote controller is an infrared remote controller attached to a conventional lighting device or a remote-controllable terminal similar to the infrared remote controller, and the pullless operation is an operation of repeatedly turning on and off the power switch in a short time.

[ In this example, three microcomputers are displayed in an array. By tapping the icon, the desired processing operation can be performed. 1c is an icon for performing the pairing setting. The icon 1c is tapped so that the next screen is opened and the execution is tapped so that the LED lighting apparatus 20 receives the S / ID transmitted together with the PDA and the D / N of the LED lighting apparatus in the mode P, And can be stored in the memory unit. 1d is an icon for displaying the illumination device list screen. By tapping the icon 1d, a screen in which LED lighting devices to be selected are displayed is displayed, and a desired LED lighting device is selected to perform various lighting controls desired by the user . For example, there are LED lighting fixtures A to N, and LED lighting fixture C among them is selected. Each icon for realizing the illumination contents according to the environment of 'morning', 'evening', and 'round' is displayed on the screen, so that by selecting one mode, the LED lighting fixture C can display the brightness or color And the like. Reference numeral 1e is an icon for setting various data of the LED lighting apparatus. By tapping the icon 1e, a specific setting screen is displayed. For example, if you adjust the brightness and color set to 'morning', display the brightness and color adjustment screen, and change the brightness to 0 ~ 100% and 0 ~ 100% Can be set.

[ The voice input / output unit 11 is a microphone and a speaker, and can also input voice inputted from the key input unit 8 by voice. The power supply unit 12 is, for example, an ion lithium rechargeable battery or the like.

3 is a block diagram showing an embodiment of a circuit of an LED lighting apparatus to be controlled in the wireless communication system according to the present invention.

A microcomputer 31, a BT antenna 21, a BT controller 22, a clock section 23, a memory section 24, a driving section 25, an LED section 26, And a power supply unit 27 are provided. Each of the circuit units excluding the power supply unit 27 is capable of transmitting and receiving data. The microcomputer 31 reads out a program for realizing the communication function of the present invention and each function of the LED lighting apparatus 20 to send a command to each block portion so as to transmit and receive each data of Fig. And realizes various functions of the LED lighting apparatus 20. [0050] The BT antenna 21, the BT controller 22 and the clock section 23 correspond to the functions of the BT antenna 6, the BT controller 5 and the clock section 4 of the portable terminal apparatus 1 of Fig. 2 do. The memory unit 24 stores a list of PDA and D / N of the portable terminal apparatus of the pairing partner formed by the operation of the microcomputer 31, and stores the PDA and D / N list for each portable terminal apparatus. Also, timer values (timer S, timer D, etc.) to be set can be stored.

The LED lighting control unit is formed by the microcomputer 31, the driving unit 25, the LED unit 26 that lights a plurality of LEDs, and the like. The microcomputer 31 executes a setting operation and each mode operation in addition to the execution of the function of the timer section 31a and also responds to the inquiry about the state of the LED illumination from the portable terminal apparatus.

4 is a diagram for explaining the flow of communication performed between the portable terminal apparatus and the LED lighting apparatus.

Paying attention to the movement of the communication, the LED lighting apparatus 20 transmits the pairing request and the user data to / from the BT controller 22 and the microcomputer 31 by the UART communication (serial signal by the preliminary synchronous method). Data packets are transmitted and received between the portable terminal apparatus 1 and the BT controller 22 by BT communication.

BT communication and UART communication are interlocked between the portable terminal apparatus 1 and the LED lighting apparatus 20 by the operation of the portable terminal apparatus 1 for the LED lighting apparatus 20. [

When the power of the LED lighting apparatus 20 is turned on, the BT controller 22 becomes mode N and starts transmission of the data packet A (PDA of the LED lighting apparatus, D / N). The data structure of the data packet A is shown in Fig. 8 (a). The data packet A is composed of a header portion, a PDA portion, and a D / N portion. The header section describes data such as, for example, source / destination, packet size and number. The PDA unit and the D / N unit describe the unique device address and device name of the LED lighting fixture.

Next, when full operation is performed in a remote control of the LED lighting apparatus installation, a LED lighting apparatus main body, or a cord switch to be supplied to the LED lighting apparatus main body, the microcomputer 31 sends a pairing request to the BT controller 22 The BT controller 22 shifts to the mode P and transmits the data packet B (S / ID in addition to the PDA and D / N) for a predetermined time. The data structure of the data packet B is shown in Fig. 8 (b). The data packet B is composed of a header portion, a PDA portion, a D / N portion and an S / ID portion. The header part, the PDA part, and the D / A part are the same as the data packet A, and the S / ID part describes the security number.

When the portable terminal apparatus 1 receives this information and performs a connection request (pairing 1c in Fig. 1 (b)), the BT controller 22 receives the information and sends it to the microcomputer 31. [ The PDA and D / N of the portable terminal device that has established the pairing are stored in the memory section 24. [ Then, the mode shifts to mode C.

When the mode shifts to the mode C, the portable terminal apparatus 1 has completed the pairing process with respect to the LED lighting apparatus 20, and the user then taps the list of lighting apparatuses of the screen example shown in Fig. 1 (b) Various operations can be performed on the lighting apparatus. When the user selects a predetermined operation content and taps and transmits the data, the data packet D is transmitted to the LED lighting apparatus 20. [ The data structure of the data packet D is shown in FIG. 8 (d) and is composed of a header portion, a PDA portion, an S / ID portion, a U / D-A portion and a check sum portion. Since the security number of the S / ID unit is included, the LED lighting apparatus 20 can be received safely. The U / D-A portion indicates control contents. For example, the brightness is set to 100%. The color of the illumination is changed. The current state of the lighting device is control data indicating how to turn on the illumination. The checksum is to check whether the transmitted packet is correctly transmitted or not. On the receiving side, one block of data is in units of 20 bytes. If the sum of the contents of the data and the checksum value coincide with each other, the data is normally received. When they are overlapped in the communication path, the data amount of the block or the data contents are changed. It is also possible to divide the data on the transmitting side, to transmit the divided data, and to check the correspondence between the data transmitted on the receiving side and the actually received data.

Of the data received by the BT controller 22, U / D-A is sent to the microcomputer 31, and processing is performed according to the contents of the user data. For example, regarding the query of the illuminator status, the U / DB is sent to the BT controller 22 as the response data, and the data packet C shown in FIG. 8 (c) 1). In U / D-B, for example, the brightness of the current illumination is 30% and the color is 70%, and the information is displayed on the reception corresponding screen of the portable terminal device 1. [ The user can check this state and change the brightness to the brightness desired by himself / herself by operating the lighting apparatus list 1d shown in Fig. 1 (b) of the portable terminal apparatus 1. [ When the operation is completed for the LED lighting apparatus 20, the user sends a cutoff request. Upon receiving the disconnection request, the BT controller 22 shifts to mode N and transmits a data packet A indicating that the disconnection has been completed.

5 is a view for explaining each mode processed by the microcomputer built in the lighting apparatus.

When power is supplied to the LED lighting apparatus, the microcomputer is ready to operate as an LED lighting apparatus, such as reading a program, and clearing the working area of the memory. After that, it enters standby mode waiting for input from remote control operation, full operation, or BT control.

The pairing mode is a mode in which a pairing operation is performed when an interrupt (INT-1) occurs due to a pull-up operation or a pairing request by a remote controller. The microcomputer sends a pairing request to the BT controller.

The control mode is a mode in which, when an interrupt (INT-2) is generated by receiving a control request from the BT controller, color output, dimming output, internal timer set, and the like are performed in accordance with the received data.

The output mode is a mode for transmitting the current lighting condition to the BT controller when an interrupt (INT-3) for receiving a transmission request from the BT controller occurs.

The timer mode is a mode in which a timer is started or terminated when an interrupt (INT-4) for receiving information that has been set by the internal timer occurs.

6 is a transition diagram for explaining the flow of control performed by the BT controller incorporated in the lighting apparatus.

The LED lighting apparatus is initialized by power-on, and then the mode N, which is the state in which the PDA and the D / N are transmitted, transmits the PDA, the D / N, and the S / P, and S / ID, and control is performed to the LED illuminator by the operation of the portable terminal device. Here, the block of the communication BT transmits the U / DB from the LED lighting apparatus to the portable terminal apparatus authenticated by the S / ID, the block of the communication U transmits the U / DA from the portable terminal apparatus authenticated by the S / To the LED lighting apparatus.

In the state of the mode N, the LED lighting apparatus is in a state of transmitting its own PDA and D / N, and if there is a pairing request (interrupt (INT-1)) from the microcomputer of the lighting apparatus, . The timer time is, for example, 10 seconds (which may vary depending on the setting), and the pairing operation is performed within this time. When the pairing is completed in the state of mode P or the timer S times out (interrupt (INT-2)), the timer S stops and returns to the state of the mode N.

Further, when there is a connection request (interrupt (INT-3)) from the portable terminal apparatus, the timer S is stopped and the timer D, which is a time for maintaining the state of the mode C next, is started.

The mode P is a mode for shifting to a case where the first portable terminal apparatus is not permitted to operate. However, the portable terminal device that has performed the pairing does not shift to this mode.

When a connection request (interrupt (INT-4)) is generated from the portable terminal apparatus in the state of the mode N, the timer D is started and the mode C is held for 30 seconds, for example. If there is a connection request (interrupt (INT-3)) in the mode P, a timer D for holding the mode C is started even after the timer S is stopped. The BT controller 22 enters the control state connected to the portable terminal apparatus by the authenticated S / ID. Then, when receiving data from the portable terminal device (interrupt (INT-6)), it is checked whether or not the transmitted user data is normally received (check sum). If the transmitted data is not normal, it returns to mode C.

If it is confirmed that it has been received normally, the timer D is brought to a deadline. Then, the S / ID transmitted as part of the data is checked. If there is no error in the S.ID, the BT controller 22 sends the user data to the microcomputer 31 by the communication U. The microcomputer 31 performs processing such as power ON / OFF, dimming, coloring and timer setting for the LED lighting apparatus in accordance with the contents of the user data.

On the other hand, if it is determined that the authentication can not be performed as a result of checking the S / ID, the connection with the portable terminal apparatus by mode C is disconnected and the mode N is entered.

The BT controller 22 receives data (interrupt (INT-7)) from the microcomputer 31 of the LED lighting apparatus and sends the data received by the communication BT to the portable terminal apparatus.

If the connection request, the timer D timeout, or the portable terminal device in connection is moved out of the communication area (interrupt (INT-5)) from the portable terminal device in the state of mode C, Lt; / RTI >

7 is a diagram for explaining each mode to be processed by the portable terminal apparatus.

The portable terminal apparatus enters a standby mode for waiting for input of each interrupt operation (INT) on the top screen by application startup. The screen example shown in Fig. 1 (b) corresponds to the standby mode.

The pairing mode is a mode in which an interrupt (INT-1) occurs and a connection request is transmitted when the user receives the S / ID of the LED lighting apparatus from the BT controller and taps the pairing screen (icon of pairing 1c) .

The operation mode is a mode in which an interrupt (INT-2) occurs when the user taps the color tone and light control screen to display the selected LED unit or group information.

In the output mode, an interrupt (INT-5) is generated by transmitting coloring data, dimming data, and ON / OFF data by designating each control content from the screen, and controlling the illumination unit of the LED lighting apparatus according to the coloring and dimming data .

The timer mode is a mode in which an interrupt (INT-3) is generated when the set timer time arrives, and the set color data, dimming data, and ON / OFF data are transmitted to the LED lighting apparatus.

In the setting mode, an interrupt (INT-4) is generated when a setting screen is tapped, and a name of a lighting apparatus, a timer value (setting time data of timers S and D, etc.), a grouping, and a scene are set. Corresponds to tapping the icon 1e of the screen example setting shown in Fig. 1 (b). For example, the timer S is set to 30 seconds, and the timer D is set to 180 seconds. The setting time can be changed by this setting mode.

The above embodiment describes an example in which a smart phone is applied as a portable terminal device. However, it is also possible to register a smart phone, a mobile phone, a tablet, etc. in addition to a plurality of portable terminal devices of the same type that can be master devices Do. In addition, the data packets A to D shown in FIG. 8 are used as the data packet structure, but it is also possible to perform BT communication with a data packet structure having a different structure.
