Embodiment 1

[0061] Embodiment one, such as figure 1 As shown, an unmanned supermarket shelf monitoring system includes a user terminal 4, an unmanned supermarket shelf monitoring device 1, a background server 2 and a management terminal 3;

[0062] The unmanned supermarket shelf monitoring device 1 includes a processing module one 11 and a photographing unit 12 coupled with the processing module one 11, an RTC alarm clock 13, and a communication module one 14;

[0063] The background server 2 includes a processing module two 21 and a communication module two 22, a storage module 23, and an image recognition module 24 coupled with the processing module two 21;

[0064] The management terminal 3 includes a processing module three 31 and a display unit 32 and a communication module three 33 coupled to the processing module three 31;

[0065] Communication module two 22 is communicatively connected with communication module one 14, communication module three 33;

[0066] After the unmanned ...

Embodiment 2

[0115] Embodiment two, such as Figure 7 with Figure 8 As shown, an unmanned supermarket shelf monitoring system differs from Embodiment 1 in that: the infrared sensor 15 is powered independently, and when the unmanned supermarket shelf monitoring device 1 is turned off, the infrared sensor set on the unmanned supermarket shelf monitoring device 1 The sensor 15 monitors in real time whether there is a human body in front of it, and when the infrared sensor 15 detects that there is a human body in front of it, and waits until the infrared sensor 15 detects that there is no human body in front again, it wakes up the unmanned supermarket shelf monitoring device 1 and starts it, and executes the preset camera program.

[0116] When the infrared sensor 15 detects that there is a human body in front of it, its signal output terminal S_out outputs a high-level signal;

[0117] The delay circuit 7, its input terminal is coupled to the signal output terminal S_out of the infrared se...

Embodiment 3

[0125] Embodiment 3, an unmanned supermarket shelf monitoring system, differs from Embodiment 2 in that the infrared sensor 15 is replaced by an ultrasonic sensor. That is, the ultrasonic sensor is powered independently. When the unmanned supermarket shelf monitoring device 1 is turned off, the ultrasonic sensor installed on the unmanned supermarket shelf monitoring device 1 monitors in real time whether there is a human body in front of it. When the ultrasonic sensor detects that there is a human body in front of it. , and wake up the unmanned supermarket shelf monitoring device 1 to start when the ultrasonic sensor detects that there is no human body blocking again in front, and execute the preset camera program.

[0126] When the ultrasonic sensor detects that there is a human body in front of it, its signal output terminal S_out outputs a high-level signal;

[0127] Delay circuit 7, whose input terminal is coupled to the signal output terminal S_out of the ultrasonic senso...

Abstract

The invention discloses a shelf monitoring device for an unmanned supermarket. The shelf monitoring device comprises a camera, a processor, a communication module I coupled to the processor, a dial switch K2, a P-channel MOS tube Q2, a DC-DC synchronous buck converter, an NPN triode Q1, and an RTC alarm clock chip. The processor is coupled to an external serial port of the camera; and after the camera shoots an image, the image uploaded to a background server connected with the camera. The dial switch K2 has an input terminal and an output terminal; the input terminal is coupled to a direct current VIN and the output terminal is connected in series with an inductor R19 and a capacitor C6 successively and then is grounded. A grid G of the P-channel MOS tube Q2 is coupled between the inductor R19 and the capacitor C6 and a source S of the P-channel MOS tube Q2 is c coupled to the direct current VIN. A collector C of the NPN triode Q1 is coupled to the grid G of the P-channel MOS tube Q2and a base electrode B is connected in series with a resistor R1 and then is coupled to a power control off terminal PWR_HOLD of the processor. According to the invention, the ultra-low-power-consumption shelf goods number monitoring is realized. The shelf monitoring device having the cargo supplementing prompting function has advantages of low power consumption, accurate identification and greatconvenience in installation.

Description

technical field [0001] The invention relates to the field of automatic vending, more specifically, it relates to an unmanned supermarket shelf monitoring device. Background technique [0002] With technological innovation and the continuous upgrading of people's consumption patterns, a variety of unmanned vending methods have gradually emerged in the market. For example, unmanned shelves refer to using a shelf, putting some food and drink, pasting a QR code, paying first and then shipping, all by self-consciousness, no one sells it themselves. This unmanned shelf is not the latest concept. Vending machines that have been around for a long time are often found in subway stations, offices, schools and other places. In fact, they are unmanned vending machines. Supermarkets without salespersons, also known as unmanned supermarkets. It is not the salesperson who is responsible for collecting money, but a safe or coin box. After the customer purchases the product, he puts the m...
