Description

[0001] WIRELESS COMMUNICATION MODULE AND METHOD FOR PROVIDING AUTOMATIC CONFIGURATION OF NETWORK [0002]

Embodiments of the present invention relate to a wireless communication module, for example, a wireless communication module and a wireless communication module that provide an automatic configuration of a network that provides a multi-function capable of configuring and changing a wireless network desired by a user in configuring a wireless sensor network .

Generally, Ubiquitous Sensor Network (USN) is defined as a network of intelligent sensors that will make ubiquitous in the future. Applications of ubiquitous sensor networks (USN) can be applied to a wide range of fields such as civil engineering, education, medical, agriculture, environment, defense, traffic and disaster. Therefore, companies in each field are interested in developing products that apply wireless sensor network (WSN) technology to their fields of interest. However, in the development of wireless sensor network (WSN) related products based on semiconductor chips for low power wireless communication, the development period usually takes 6 to 18 months and costs about 200 million to 650 million won. The development period and cost can be further increased according to the technology of the product to be developed, the frequency of use, the related product technical standard, and the country-specific certification system. Whenever the supply situation of the semiconductor chip producer for communication is changed, Can be further increased. For the above reasons, many companies are pursuing product development in the direction of purchasing and making convenient use of existing module type wireless sensor network (WSN) related products. Therefore, companies with wireless communication technologies are bringing related products for modular wireless sensor networks (WSN) to the market.

Meanwhile, a radio frequency (RF) technology applicable to a semiconductor chip for a low power wireless communication that can be used in a low power wireless sensor network (WSN) includes a wireless LAN specified in IEEE 802.11.x, a Bluetooth specified in IEEE 802.15.1 ) And ZigBee (defined in IEEE 802.15.4). The advantage of Wi-Fi is that it has a great deal of security, it can transmit a large amount of data and is highly secure, while complicating protocol specifications, taking a long time to connect, , The power consumption is so large that it is not suitable for products using batteries. Bluetooth is a communication standard suitable for sending and receiving voice signals, which is useful for a communication device that requires multiple functions, but has a relatively high unit price and large power consumption. ZigBee is attracting attention as a technology that can solve the problems of battery power consumption and production cost compared to wireless LAN and Bluetooth. However, ZigBee needs a relatively large and complicated communication protocol stack internally, and requires an expert with expertise to program it, and it is inconvenient to develop applications using an external host processor. In addition to the above mentioned technologies, many companies are interested in Z-Wave, which improves the inconvenience of ZigBee, and Bluetooth low energy (BLE), which improves the problems that impede the application of Bluetooth to the wireless sensor network (WSN) The number of applications for product development is increasing.

Therefore, manufacturers of wireless communication modules are introducing modular products for wireless sensor networks (WSN), which are applied to semiconductor chips for low power wireless communication and radio frequency related technologies. The user or the developer is required to transmit the data to be transmitted stably to the desired place within the allowable time rather than the structure included in the module such as the radio frequency type, internal data link structure, and routing protocol format employed by the module It's a top priority.

Although existing module for wireless sensor network (WSN) has a network structure of standard or nonstandard type including software of some type in the inside, the following common problems are seen from the viewpoint of users There is always a problem that the user needs to develop a product in order to solve the problem by constructing a solution inside the external host processor.

1. An external host processor is essential for simple product application. For example, the wireless communication module does not perform any active role by itself, but performs only a thorough passive role.

2. When the user applies to the product, the parent application and protocol must be separately developed and applied on the host processor.

3. Because the host application processor develops the upper application protocol separately according to its own needs, compatibility problem with other products occurs.

4. Since the use of the host processor is essential, it is difficult to minimize power consumption and additional power consumption occurs.

5. Because the address allocation format that distinguishes each module is closely connected to the communication protocol and the adoption algorithm in the module, user convenience, flexibility, creativity, etc. can not be applied by excluding the user's choice originally, .

If the value of the address setting switch (not shown) has a value other than 0, the control unit 110 can perform manual address setting. The manual address setting is performed by setting the address of the wireless communication module 100 providing the automatic configuration of the network to the value of the address setting switch (not shown) connected to the address setting port 160 by the MCU 112 of the controller 110 .

On the other hand, when the address setting switch (not shown) is not connected or the value of the address setting switch (not shown) is 0, the control unit 110 stores the address stored in the setting value storage area It is possible to determine whether or not the setting parameter exists.

For example, the address setting value may be generated based on the last hexadecimal 4-digit value of the hexadecimal 16-digit value of the product-specific serial number and stored in the storage unit 120.

When the wireless communication module 100 providing the automatic configuration of the network enters the network ID setting mode, the controller 110 can determine whether the address setting port 160 and the network ID setting switch (not shown) are connected. As a result of the determination, when the network ID setting switch (not shown) is connected, the controller 110 may determine whether the value of the network ID setting switch (not shown) is not zero.
