Technical problem that is complicated, being not convenient to use is safeguarded, realizes and simplifies installation, maintenance cost is relatively low, is easy to large-scale promotion, makes
With convenient technique effect.
It is below in conjunction with the accompanying drawings and specific real in order to be more clearly understood that the above objects, features and advantages of the present invention
Mode is applied the present invention is further described in detail.It should be noted that in the case where not conflicting mutually, the application's
Feature in embodiment and embodiment can be mutually combined.
Many details are elaborated in the following description to facilitate a thorough understanding of the present invention, still, the present invention may be used also
To be implemented using other different from the other modes in the range of being described herein, therefore, protection scope of the present invention is not by under
The limitation of specific embodiment disclosed in face.
Wireless commodity attention rate harvester in the application uses the wireless acquisition device of smallerization, directly hangs
(it need not be installed) on commodity, data acquisition uses wireless mode.This mode simplifies installation, maintenance cost, is easy to big
Scale is promoted.In addition, which is counted using the mode of vibrations to attention rate, eliminate RFID apart from it is limited the defects of.
Operation principle is as shown in figure 1, whole system is made up of n collector and a receiver；Receiver and computer
It is attached by serial ports, the concern counting that collector is sent, which is sent to computer, to be handled.
Collector principle is counted to receiver for sending attention rate as shown in Fig. 2 wherein RF is radio frequency chip；MCU is
The bit processor of micro energy lose 8；Vibroswitch can select mercoid switch either micro-vibration switch.
RF is connected with MCU by bus, usually I2C, SPI, ULTRA either parallel bus.Vibroswitch and MCU's
One interruption IO connection.Work-based logic：
When MCU is flat power consumption is reduced in sleep mode.
MCU wakes up from sleep mode two ways：1st, timer is waken up (every 30 minutes or so) in 2, vibroswitch
It is disconnected to wake up；When commodity are picked up by potential customers to be selected, vibroswitch causes MCU interruption to wake up；MCU is begun through
I/O interrupt is calculated commodity attention rate；It is a time-continuing process because commodity are selected, therefore algorithmically can consider
In one time interval (such as：10 seconds) multiple interruption may be considered and once pay close attention to；When timing wake-up, MCU openings RF (for
Power saving, is closed when RF is flat), send attention rate to receiver and count (communication protocol is explained below).
Receiver principle is as shown in figure 3, the RF of receiver is connected by bus with MCU；MCU is connected by serial ports and computer
Connect and communicate.Different from collector, receiver is connected to computer, therefore RF, MCU work always, and RF always works at reception
Pattern.
Communication explanation is as shown in Figure 4：
After a timing cycle of collector is come, MCU is waken up, and MCU powers for RF, and sends " hair to receiver
Send and count frame "；Collector one time (about 200ms) of delay, waits the response of receiver；After receiver receives " counting frame ",
" remove and count " frame is sent to collection；After collector receives " remove and count " or is a time out, dormancy is reentered.
The premise of wireless telecommunications is unreliable link, it is necessary to consider.Here it is related to two communication frames：
1st, send and count frame：It is main to include collector unique identifier UUID, serial number, concern counting；
2nd, remove and count frame：Mainly include collector unique identifier UUID.
Every several minutes of collector (30 minutes or so) sends the concern of oneself to receiver and counted.Wherein UUID is used to identify
It is which commodity.Serial number adds up since 1, and concern counting is the number that the collector is picked up by customer.Need exist for considering
Receiver not necessarily can reliably receive the data of collector, or the removing that sends of receiver count frame not necessarily can be by
Collector receives.
After receiver effectively receives the data of collector, UUID, stream are sent to computer by serial ports or network
Water number, concern count three data；Carried out more as the concern degrees of data of the commodity corresponding to computer software is the UUID
Newly；If computer statisticses software discovery serial number does not change, the flowing water of this data in upper once same UUID is represented
It is not cleared in the case of number.May determine that reason is that " remove and count " not collected device effectively receives.
After receiver effectively receives the data of collector, " remove and count " frame is sent to collector.
Collector not necessarily effectively receives " remove and the count " frame sent during this time by receiver.When collector is effective
(judge whether it is that oneself should be received by UUID) after receiving " remove and count " frame, serial number plus 1, and focused data
Reset；Failing to effectively receiving " remove and count ", serial number is constant, and concern is counted and do not reset.
Above-mentioned communication process because carry out, therefore communication process is unreliable in the wireless context.Pass through serial number
Mode, ensure that computer software knows the implication of focused data.
Although preferred embodiments of the present invention have been described, but those skilled in the art once know basic creation
Property concept, then can make other change and modification to these embodiments.So appended claims be intended to be construed to include it is excellent
Select embodiment and fall into having altered and changing for the scope of the invention.
