Study On Hardware Kit Of Bluetooth Office Automation System In NaYong Power Plant Guizhou Province

Bluetooth becomes the focus in the world as a new technology on wireless connection in a short distance. Bluetooth is specified to replace the cable of many devices. In the paper, the bluetooth technology is used to found a office automation kit on the basis of the electric power product system, the scheduling manage system, market system and the applications for the enterprise, which is good to improve the level of the office automation, and the condition in office. In this paper, we also design the embedded instrument with bluetooth to realize remote control measure the device to solve the difficulty of using the cable.The technical standard of Bluetooth is a systemic solution which comprises the hardware software and the demand of interoperability. It is implemented in tiny inexpensive short-range transceivers in the mobile devices that are available today, either embedded directly into existing component boards or added into an adapter device such as a PC card inserted into a notebook computer. Bluetooth wireless technology uses the globally available unlicensed ISM radio band of 2.4GHz and its topology is best described as a multiple piconet structure. It implements the wireless communication with data and voice, by the combination of circuit switching and packet switching.The paper builds the application model by lucubrating the protocol and profile of Bluetooth.1). Using fiber as the backbone network in Nayong power plant.2). Realizing the interlinkage and sharing resource in every office with bluetooth.3). Developing the embedded instrument with bluetooth to realize remote control measure the device. Building the hardware kit by the bluetooth RF, baseband and LCP.4). Developing some application programs to build the software kit.On the basis of the model, the hard kit of Nayong power plant office automation with bluetooth's research tasks are as follows:1. designing a routing scheme in the bluetooth wireless networks. On the basis of the practical instance, the communications among the pics should route inside the office not the LAN in the plant to realize the shortcut and high efficiency, save the networks spending, lighten the load of the networks, entend the communication distance, the newBluetooth routing scheme in the paper is based on the latest Bluetooth Protocol.2. Developing the embedded instrument with bluetooth to realize remote control measure the device in allusion to the atrocious condition in the plant. The embedded instrument can communicate with host the by the interface of bluetooth which can solve the difficulty of using the cable in this area and avoid the high error code rate. In the paper, we select the TMS320VC54x DSP and the ERICSSON bluetooth module, on the basis of RFCOMM, developing a embedded instrument.3. Testing the bluetooth office automation networks in the Nayong power plant. In order to prove the reliability and validity, we use the Tektronix's BPA100 protocol analyser to test the bluetooth networks, in order to ensure the rignt run in the wide scope and validate the interoperability of each device. The result show that the office automation system in Nayong power plant can improve the level of office automation. The routing scheme is fit for the power plant, all communications in the networks can route right. When the bluetooth gateway is used, the customs can access the device without fixed IP address by LAN.
