2) design of bluetooth module:
The selection of bluetooth mode
Bluetooth 2.1 versions+EDR and 3.0 editions+HS of bluetooth so-called " traditional bluetooth technology ", bluetooth 4.0 is replenishing of bluetooth 3.0+HS standard, towards the wireless solution that cost and power consumption are all had higher requirements, is called as " bluetooth low power consuming technology " specially.The ultra-low power consumption wireless technology is the symbolic characteristic of bluetooth 4.0 technology.Below be principal character and the difference of several bluetooth standards:
Bluetooth 3.0 has been used the Wi-Fi technology according to 802.11 adaptation layer protocols, has greatly improved transmission speed.Like this, bluetooth 3.0 equipment can be connected to miscellaneous equipment by Wi-Fi and carry out data transmission.Its core be " Generic Alternate MAC/PHY " (AMP), this is a kind of brand-new alternating radio frequency technology, allows bluetooth protocol repertory dynamically to select correct radio frequency for arbitrary task.By integrated " 802.11 PAL ", the data transmission rate of bluetooth 3.0 has been brought up to about 24Mbps, is the octuple of bluetooth 2.0.And bluetooth 4.0 is the upgrading standard of bluetooth 3.0, is replenishing of bluetooth 3.0+HS standard.It is power conservation techniques that bluetooth 4.0 is compared bluetooth 3.0 most important characteristics, and extremely low operation and stand-by power consumption can make button cell continuous working several years.In addition, low-cost and stride vendor interoperability, 3 milliseconds low postpone, more than 100 meters extra long distance, AES-128 to encrypt also be the characteristic of bluetooth 4.0.
This time design alternative has bluetooth 4.0 standards of extremely low operation and stand-by power consumption as the standard agreement of bluetooth module.Bluetooth 4.0 is supported two kinds of deployment way: double mode and monotype.In double mode, the low-power consumption Bluetooth function is integrated in the existing classical bluetooth controller, or increases the low-power consumption storehouse at existing classical Bluetooth technology chip, and overall architecture is substantially constant, and cost increases limited; Monotype uses a lightweight articulamentum to provide operate in standby mode, the simple device of super low-power consumption to recover and reliable point-to-multipoint data transmission towards highly integrated, compact equipment.
Although the monotype chip is ultralow power consumption Bluetooth chip, it is only can not realize mutual communication with other monotype chip and double mode chip communication with traditional Bluetooth technology.And double mode chip can communicate with other double mode chips that adopt the normal blue dental structure with traditional Bluetooth technology.On compatibility, double mode chip can be fully backward compatible.Consider that the employed bluetooth equipment of people does not extensively adopt bluetooth 4.0 standards in the actual life, the overwhelming majority still adopts traditional bluetooth technology, for most terminal devices can be connected with the portable glucose meter of this design, compromise between the two in compatible and low energy consumption, select double mode chip as the low energy consumption bluetooth module of this design.Embedded scm is developed bluetooth module by host controller interface, to realize specific function.Structural representation is shown in accompanying drawing 2.
3) model selection of power management module:
Stipulated in the bluetooth standard that bluetooth module has Holdover mode, breathing pattern and three kinds of power supply energy saver modes of park mode under connection status, add normal activity pattern, the bluetooth equipment of a use power management can be in these four kinds of states and switch.Put in order from high to low according to electric energy loss and to be followed successively by activity pattern, breathing pattern, Holdover mode, park mode.Wherein, the park mode energy-saving efficiency is the highest.
Normal duty when activity pattern is equipment connection, the bluetooth equipment that is in activity pattern uses all available time slots to play an active part in communication, and data throughout is the highest, thereby the loss of power is also maximum; During breathing pattern, main equipment is only namely breathed time slot at specific time slot and is sent data; Holdover mode is realized regularly jumping out with the transmission of data immediately by timer internal, is in Holdover mode in case connect, and this just connects no longer supported data bag transmission; Neither send under the park mode, receive data, can not safeguard the link of having set up, only keep and channel reduce synchronously power attenuation between nonmobile phase.Therefore, park mode has lower occupy ratio, and energy-saving efficiency is also the highest.Be fit to use park mode for the communication mode with demblee form, in the time of not using Radio Link, be placed in dormant state from equipment, as long as appropriate beacon interval is set.Can when the user need to send data, withdraw from rapidly park mode from equipment and ask to send, thereby make terminal device not only have higher energy-saving efficiency, can also realize the quick response of application program simultaneously.
Because generally in 500bit/s ~ 1000bit/s scope, transmitted data amount is little and speed is lower for the transfer rate V of blood glucose meter measurement data.Consider various factors, selecting the standby mode of bluetooth module is park mode.The electric source modes that accompanying drawing 3 is surveyed bluetooth module in the blood sugar overall process for blood glucose meter switches synoptic diagram.When terminal device search and request and bluetooth module connected, the power management routines in the MCS-51 series monolithic sent instruction to bluetooth module, and the control bluetooth module switches to activity pattern from park mode.After the Bluetooth pairing success, wait for that test module starts, at this moment, bluetooth module reenters dormant state.After success obtained measured value, single-chip microcomputer was again controlled bluetooth module and is entered activity pattern, carries out the transmission of blood glucose value.Behind the DTD, bluetooth module is got back to again park mode.Like this, utilize the power management routines on the single-chip microcomputer, switch flexibly the electric source modes in the bluetooth module.Both guaranteed the real-time Transmission of data, also so that the energy consumption of power supply drops to minimum.
3, beneficial effect
The present invention can utilize existing portable glucose meter, carries out on its basis improvement and bring new ideas.Utilize the function of Bluetooth communication of the terminal devices such as smart mobile phone, computer and portable glucose meter, display screen and storage card by these hand-held intelligent terminal equipment, the test of control blood glucose meter, data transmission, data show and preserve, thereby save demonstration and the function button part of blood glucose meter self, more dwindled the size of blood glucose meter, power consumption was lower when blood glucose meter was normally moved.Adopt up-to-date bluetooth 4.0 standards, design a kind of high portability of the data transmission between the terminal devices such as blood glucose meter and smart mobile phone, blood-sugar detecting instrument of low-power consumption finished in the Bluetooth wireless transmission mode.In addition, by in the MCS-51 single-chip microcomputer, writing the power supply control supervisor, switch more flexibly the powder source management mode of bluetooth module, improve the serviceable life of battery in the blood glucose meter.Can not only reduce cost like this, strengthen the attractive force to the consumer, and make the portable use of blood glucose meter have more feasibility, satisfy the consumer to the demand in market.
