Technical background
In retail trade, along with the rise of the emerging marketing methods such as experience type sale, the excavation of sales data real-time statistics, require the data in sales process are carried out to Real-time Collection and feedback.Utilize sensor can realize the Real-time Collection to condition of merchandise information, and utilize the RFID technology by data feedback to backstage.And changing the lasting time according to condition of merchandise can carry out effectively analyzing and excavating to the data that gather, and obtains Useful Information, as the interested number to commodity, the effective attention rate of these commodity etc.
But the sensor of existing equipment generally be take vibration transducer as main, mainly the state of energy qualitative analysis article, be difficult to accomplish quantitative test, particularly human factor, causes the sensor long-term work, and power consumption is high, and serviceable life is short.
Simultaneously the general radio frequency transmission circuitry of existing Wireless Data Transmission need be outside power supply electricity is arranged always, so sensor device power consumption always, the whole life-span is limited.
Summary of the invention
The object of the invention is to the problem for above-mentioned existence, propose a kind of low-power consumption, in real time high, reliable Wireless Acceleration Sensor device.For this reason, patent of the present invention is by the following technical solutions:
The Wireless Acceleration Sensor device, it is characterized in that this device comprises radio micro electronic mechanical system (MEMS, Micro electro Mechanical Systems) acceleration sensing detection means, energy-storage travelling wave tube, governor circuit, half active RFID integrated circuit and antenna thereof form, described acceleration sensing detection means is connected on the comparator circuit in governor circuit, governor circuit is connected with the digital interface of half active RFID integrated circuit by synchronous serial Peripheral Interface (SPI), the analog interface of half active RFID integrated circuit is connected with energy-storage travelling wave tube, energy-storage travelling wave tube is connected with governor circuit and acceleration sensing detection means.
Further, described governor circuit is comprised of microprocessor, quartz crystal oscillator, described comparator circuit.
Described energy-storage travelling wave tube can adopt electric capacity.
The frequency of operation of half active RFID integrated circuit is high frequency 13-14MHz or ultrahigh frequency 860-960MHz or 2.4GHz-2.5GHz.
Owing to adopting technical scheme of the present invention, the present invention is by effective combination of RFID technology and acceleration detection technology, can collect by the accekeration of test item the information that is concerned of article, and in conjunction with the RFID identity information, utilize RFID radio frequency transmission function to the backstage transmission information, thereby realized the data in sales process are carried out to Real-time Collection and feedback.
And startup of the present invention must meet a default magnitude of voltage (being also the magnitude of voltage of corresponding acceleration rate threshold), lower than this magnitude of voltage, the present invention can log-on data not store, in the low-power consumption standby state.
Once governor circuit detects the detected accekeration variation of described acceleration sensing detection means and is greater than threshold value, be waken up, start RFID radio frequency transmission function to the data in the transmission memory of backstage, once accekeration lower than setting threshold values, device enters again dormancy.
The present invention simultaneously is without external power source, half active RFID integrated circuit has also served as charging circuit, can accept electromagnetic signal and convert electric energy to, to energy-accumulating element, charges simultaneously, work of the present invention is powered by energy-accumulating element, has both realized real-time online and has significantly reduced the maintenance cost of businessman.
