Abstract

The utility model provides a wireless intelligent weighing counter which comprises a detection module, a main control module, a user interaction module, a storage module, a power source module and a wireless communication module. The wireless intelligent weighing counter is characterized in that the main control module is respectively connected with the detection module, the user interaction module, the storage module, the power source module and the wireless communication module, and the power source module is further respectively connected with the detection module, the user interaction module, the storage module and the wireless communication module. Real-time tares and the weight of a single object are set by a user through the user interaction module and stored through the storage module, total weight of the objects is collected by the detection module, and calculated and processed through the main control module, the number of the objects is countered, the detected weight is displayed through the user interaction module and sent to a personal computer (PC) machine wireless receiving end through the wireless communication module for centralized processing and display.

Description

The intelligent wireless counting machine of weighing

Technical field

The utility model relates to a kind of counting machine of weighing, the especially intelligent wireless counting machine of weighing.

Background technology

Along with socioeconomic development, packaging for foodstuff also progressively becomes inner wrapping by large packing, often needs in the production process inner wrapping product of some is packed in the finished product box, so that transportation and selling.At present, this operation is finished by artificial counting mostly.Inner wrapping product quantity because all odjective causes, artificial counting are packed in the finished product box often produces error.If the product quantity in the finished product box is more than the nominal quantity on the finished product box, manufacturer is stood to lose make its productive costs increase the interior product quantity of finished product box, if be less than nominal quantity on the finished product box, the customer is stood to lose and then the prestige of manufacturer is suffered damage, the interests of manufacturer are suffered damage.

Summary of the invention

The error of bringing in order to overcome artificial counting, characteristics according to this operation, the utility model provides a kind of intelligent wireless counting machine of weighing, take micro controller system as core, take Wireless Data Transmission and weighing technology as means, the algorithm of employing science can eliminate because the counting error that weight error accumulation causes, finally guarantee in the finished product box the inner wrapping product counting accurately.

The utility model provides a kind of intelligent wireless counting machine of weighing, comprise detection module, main control module, user interactive module, memory module, power module, wireless communication module, it is characterized in that: main control module is connected with detection module, user interactive module, memory module, power module, wireless communication module respectively, and power module also is connected with detection module, user interactive module, key-press module, memory module, wireless communication module respectively.The user sets the weight of instant tare weight and single body by user interactive module, and store by memory module, detection module gathers the total weight of object, through the main control module computing, object is counted, the weight that detects is shown by user interactive module, and be sent to PC wireless interface receiving end by wireless communication module, focus on and show.

The beneficial effects of the utility model are, various states that can the implementing monitoring scene show weight and the number of current testee, zero clearing peeling, average substance, memory function, transmission over radio, can make packaging for foodstuff enterprise obtain preferably economic and social benefit, have higher practical value.

Description of drawings

Fig. 1 is functional block diagram of the present utility model.

The specific embodiment

In Fig. 1, a kind of intelligent wireless counting machine of weighing, comprise detection module 1, main control module 2, user interactive module 3, memory module 4, power module 5, wireless communication module 6, it is characterized in that: main control module 2 is connected with detection module 1, user interactive module 3, memory module 4, power module 5, wireless communication module 6 respectively, and power module 5 also is connected with detection module 1, user interactive module 3, memory module 4, wireless communication module 6 respectively.The user sets the weight of instant tare weight and single body by user interactive module 3, and store by memory module 4, detection module 1 gathers the total weight of object, through main control module 2 computings, object is counted, the weight that detects is shown by user interactive module 3, and be sent to PC wireless interface receiving end by wireless communication module 6, focus on and show.

It is core that main control module 2 adopts the 89C52 micro controller system of atmel corp; the 89C52 micro controller system reads the setting value of tare weight and single body weight from the P0 mouth; and setting value is saved in the memory module 4; memory module 4 has adopted low-power consumption high-capacity flash memory chip SST28VF040A; write-protect mechanism is arranged, use by the compatible bus of high speed SPI.Detection module 1 function is that the resistance value of resistance strain gage in the LOAD CELLS is changed into magnitude of voltage output, and LOAD CELLS adopts the bridge-type equal arm bridge.Testee passes through LOAD CELLS, the weight that detects is shown by user interactive module 3, user interactive module 3 is comprised of key circuit and display circuit, drive by 8279, display circuit and key circuit have adopted the OLED display chip C0283QGLC-T of strange brilliant photoelectricity and PIC16F724 touch key-press to consist of.The 89C52 micro controller system can be calculated total number of object and shown by display circuit according to the single body weighing scale of setting, then by radio receiving transmitting module 6 data message is sent to upper PC wireless interface receiving end, what radio receiving transmitting module 6 adopted is the NRF401 radio transmitting and receiving chip of NORDIC company, adopt the FSK modulation-demodulation technique, data transmission rate is 20kbps, does not need data are encoded.Emissive power is adjustable, adopts differential antennae, transmit-receive sharing.Consider radio-frequency interference, radio frequency part is done separately a pcb board, and its core is transceiving integrated nRF401 chip, comprises the functions such as FSK modulation and demodulation, PLL are synthetic, multi-frequency switching, has the characteristics such as low in energy consumption, that peripheral cell is few.Power module 5 through rectifying and wave-filtering, provides stable 5V voltage to whole system to power by 7805 chips by alternating current.
