Compared with prior art, overlength distance bluetooth communication of the present utility model, when guaranteeing low cost, module miniaturization, makes the communication distance of bluetooth module reach 400～500 meters.
Accompanying drawing explanation
Fig. 1 is the structural representation preferred embodiment of overlength distance bluetooth communication of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, overlength distance bluetooth communication of the present utility model is described in further detail, but not as to restriction of the present utility model.
With reference to Fig. 1, it is the structural representation preferred embodiment of overlength distance bluetooth communication of the present utility model.This preferred embodiment in, overlength distance bluetooth communication comprises substrate and is arranged at Bluetooth communication portion and the radio communication portion on substrate.Bluetooth communication portion comprises Bluetooth chip, balun circuit, impedance matching circuit and the 3dBi ceramic antenna connecting successively; Radio communication portion comprises 915MHz radio frequency chip, match circuit, radio-frequency (RF) switch and the ceramic antenna connecting successively; Between Bluetooth chip and 915MHz radio frequency chip, connect.In the present embodiment, Bluetooth chip is CC2540 chip, and 915MHz radio frequency chip is SI4432 chip.
The low-power consumption bluetooth 4.0SOC chip that the design of CC2540 Bluetooth chip ShiTI company is produced, it comprises 8051 microcontrollers; SI4432 chip is the rf chip that the design of Cilicon LABs company is produced, and it needs external micro-control unit (MCU) to carry out control operation to it.Therefore, can utilize 8051 microcontrollers of CC2540 inside by GPIO SPI-bus analogue, SI4432 to be controlled,, master controller using the CC2540 while as Bluetooth communication portion and radio communication portion, on 8051 microcontrollers, move Bluetooth communication protocol stack program, radio communication protocol stack program, radio-frequency (RF) switch control program and other software and hardware control programs, thereby can realize the communication function of Bluetooth communication portion and radio communication portion simultaneously.
In addition, CC2540 chip also comprises internal storage, the internal storage that SI4432 chip can read and write access CC2540 chip.So just realized the data penetration transmission of Bluetooth communication portion and radio communication portion, a Department of Communication Force in Bluetooth communication portion and radio communication portion can forward the data that another Department of Communication Force sends or receives.
915MHz radio frequency communication distance can reach 500 meters of left and right easily, SI4432 built-in chip type the power amplifier module of 20dB, its receiving sensitivity is-121dBm, therefore can realize stabilized communication distance far away.Utilize 915MHz radio communication blue-teeth data can be sent to larger distance, thereby realized the Bluetooth communication of overlength distance, such as can for example, so that the communication distance between the mobile phone of built-in this module and other equipment (, scanner equipment) reaches 400～500 meters.
Take this module for smart mobile phone and communicate with scanner equipment the operation principle that this module is described as example.The transfer of data that scanner control software in smart mobile phone sends needs by Bluetooth protocol is to this module, and the Bluetooth chip in this module is transmitted to the blue-teeth data receiving the 915MHz radio frequency chip in this module and controls radio frequency chip and carry out data transmission; 915MHz radio frequency chip in scanner equipment receives data, according to the control command of carrying in data, processes, and return data is given this module afterwards; 915MHz radio frequency chip in this module receives these data of returning and is transmitted to Bluetooth chip, and the scanner that Bluetooth chip sends the data in smart mobile phone by Bluetooth protocol is again controlled software.So, just realized the exchanges data between smart mobile phone and scanner.
Overlength distance bluetooth communication of the present utility model, can increase the communication distance of bluetooth communication greatly, makes its communication distance reach 400～500 meters.Owing to realizing at the inner integrated RF Department of Communication Force of bluetooth communication, reduced the cost that external module brings, and realized the miniaturization of module.Meanwhile, the user of bluetooth communication does not need to buy and install other modules yet just can realize telecommunication, thereby has improved user's experience.
Above embodiment is only illustrative embodiments of the present utility model, can not be for limiting the utility model, and protection range of the present utility model is defined by the claims.Those skilled in the art can make various modifications or be equal to replacement the utility model in essence of the present utility model and protection range, these modifications or be equal to replacement and also should be considered as dropping in protection range of the present utility model.
