[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention. Obviously, the embodiments described in the present invention are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0029] In addition, the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0030] The following takes a mobile phone stored in a turnover box as goods to make a detailed description of the monitoring system and monitoring method of the present invention.

[0031] Embodiment 1: The specific structure of the present invention is as follows: Please refer to the attached Figure 1-8 A monitoring system capable of counting the number of goods in a turnover box of the present invention includes a turnover box, multiple groups of detection modules 10, a main control board, a display module, a wireless communication module, at least one gateway module, and a cloud platform server.

[0032] A turnover box with an ID number, and a plurality of positioning slots for positioning goods are distributed inside the turnover box.

[0033] Multiple groups of detection modules 10 are arranged inside the turnover box. In any group of detection modules 10, a plurality of detection sources 20 are provided. All the detection sources 20 on the multiple groups of detection modules 10 are arranged in a one-to-one correspondence with the plurality of positioning slots. The detection source 20 is used to detect whether there is goods in the corresponding positioning slot. The detection module 10 sets a position information number for each detection source 20; the detection source 20 can emit an infrared LED lamp. The detection module 10 is also called an infrared detection board, and the distance between any two adjacent detection sources 20 is adjustable. As Figure 5 shown, Figure 5It is a schematic diagram of an infrared detection board. Three infrared detection boards are used to monitor the insertion and removal of mobile phones in real time. Each detection board has 16 detection positions, with a total of 3 columns. A turnover box can accommodate 48 mobile phones. When a mobile phone is inserted into the groove and detected by infrared, it will be judged that there is a mobile phone, and at the same time, the position and quantity will be transmitted to the main control board through the serial port. The distance between adjacent infrared detection points can be adjusted by adjusting the baffle structure to adapt to the thickness of mobile phones on the market (about 6 - 7.5 mm). In the present invention, it is set to 24 mm to ensure the detection effect.

[0034] The dots represent the detection source 20, and the rhombus indicates that a mobile phone is inserted into the positioning groove. As Figure 5 can be seen, the detection source 20 corresponding to the rhombus transmits the mobile phone position information and quantity information to the MCU in real time through the serial port, and the MCU displays the mobile phone position information and quantity information through the e-ink screen.

[0035] The main control board is arranged in the turnover box. The MCU on it communicates with each detection module through the serial port. The MCU uses the interrupt processing method to receive the data collected by each detection module and control the power supply of each detection module. The detection module transmits the goods position and quantity detected by the detection source to the MCU through the serial port. The MCU and the external line detection board communicate through the serial port and adopt the interrupt processing method to control the power supply to the detection board at the same time. When the infrared detection board detects the insertion or removal of a mobile phone, it will send an interrupt signal, as well as the detected position and number, to the main control board, and the interrupt signal will wake up the main control board for data processing.

[0036] The display module is arranged at a visible position outside the turnover box and is connected to the MCU. The MCU controls the display module to display the received goods position information and quantity information in a dot matrix display mode. The MCU also controls the display module to display the ID number of the turnover box. The display screen of the display module uses an e-ink screen. The dot matrix display has 3 rows, and each row has 16 rectangular blocks, which can intuitively show the specific position and quantity of mobile phones placed in each column, facilitating manual verification. At the same time, the ID number of the turnover box will be displayed for LoRa communication and identification. Using the e-ink screen improves the readability of the screen and reduces the power consumption of the system.

[0037] As Figure 4 shown, Figure 4 the ID displayed on the e-ink screen is 10010666, indicating that the e-ink screen displays the position and quantity of mobile phones in the turnover box numbered 10010666. Among them, the first infrared detection board has 16 mobile phones and the mobile phone position information is clearly displayed. The second infrared detection board has 5 mobile phones and the mobile phone position information is clearly displayed. The third infrared detection board has 3 mobile phones and the position information is clearly displayed. The total number of mobile phones on the three infrared detection boards is 24.

[0038] Through the e-ink screen, the staff can intuitively know the number of mobile phones in the turnover box of a certain ID and the corresponding positions of each mobile phone through the e-ink screen.

[0039] The wireless communication module is arranged on the main control board and connected to the MCU. Preferably, the wireless communication module used is a LoRa wireless communication module, and the antenna of the LoRa wireless communication module is an in-built spring antenna.

[0040] The gateway module establishes wireless communication with the wireless communication module; the gateway module used is a LoRa gateway.

[0041] The number of mobile phones in the turnover box is wirelessly sent to the gateway module through LoRa. The factory can view and trace the number of mobile phones in the turnover box on the platform and evaluate the production capacity of the workshop. The use of an in-built spring antenna avoids the risk of pulling of an external antenna and facilitates the handling of the turnover box.

[0042] Deploy the positions and quantities of LoRa gateways according to the size of the factory workshop. LoRa communication has the characteristics of low power consumption and long distance, and is suitable for transmission in large spaces such as factories. And the risk of packet collision can be avoided by configuring the transceiver frequency points, increasing the reliability of wireless communication. At the same time, it can be uploaded to the cloud platform through 4G, facilitating the systematic management of the factory.

[0043] The cloud platform server receives the information transmitted by the gateway module through the communication signal and stores it for viewing. The communication signal is one of 4G signal and 5G signal. Preferably, the 4G signal is selected for transmission in this embodiment.

[0044] A power module electrically connected to the MCU and a Bluetooth module electrically connected to the MCU are further arranged on the main control board. The Bluetooth module supports the user to connect to the infrared detection board through Bluetooth, configure the reporting period, sending and receiving frequency points, and can reduce the probability of packet collision of multiple main control boards in the same workshop area. The power module is provided with 1 battery box and uses 3 common No. 5 alkaline batteries. The battery can be disassembled and replaced when it runs out of power.

[0045] A GPS module and an RFID module electrically connected to the MCU are further arranged on the main control board. The GPS module is used for positioning, and the RFID module is used for quick identification of the scanned device.

[0046] A wiring transfer board is further arranged in the turnover box of the present invention. There is 1 wiring transfer board, which is used for the transfer of the internal wiring of the turnover box. The wiring and terminals are inserted in a butt-joint manner, facilitating the workers to install the detection board and the main control board, and to disassemble and repair or replace them when the detection board / main board is damaged.

[0047] Embodiment 2: A monitoring method of the present invention, the monitoring method comprising the following steps: Step 1, set the ID of the turnover box and set the position information numbers of each infrared detection source; Step 2, use the infrared detection source to detect the change of the goods state in the positioning slot in real time, and send the position information and quantity information of the goods to the MCU in an interrupt manner through the serial port; Step 3, the MCU is awakened after receiving the interrupt signal and performs data processing; Step 4, the MCU converts the data into an image for ink screen display and displays it in the form of a dot array, intuitively showing the goods position, the quantity of goods, and the turnover box ID number; Synchronously, the MCU sends the goods quantity data to the gateway module through LoRa communication; Step 5, the LoRa gateway module collects the data sent by multiple main control boards and uploads it to the cloud platform server through 4G signals for viewing.

[0048] Specifically, install 3 infrared detection boards in the turnover box according to the designed positions, connect the cable to the main control board through the adapter board to ensure a stable connection. Install the battery box and load 3 No. 5 alkaline batteries to supply power to the main control board and the detection board. Fix the main control board in a suitable position to ensure that there are no obstacles around its built-in spring antenna to ensure the LoRa communication effect.

[0049] Parameter configuration: The user connects to the main control board through Bluetooth and configures the reporting period, sending and receiving frequencies according to the actual situation of the workshop to reduce the probability of packet collision with other main control boards. At the same time, the ID number of the turnover box can be set for identification and management in the system.

[0050] Workflow: When a mobile phone is placed in or taken out of the groove (also called the positioning slot) of the turnover box, the infrared detection board monitors the state change of the mobile phone in real time, and sends the position and quantity information to the main control board in an interrupt manner through the serial port. The main control board is awakened after receiving the interrupt signal and performs data processing. On the one hand, it converts the data into an image for ink screen display, intuitively showing the placement position and quantity of the mobile phone and the turnover box ID number; on the other hand, it sends the mobile phone quantity data to the indoor gateway through LoRa communication. The LoRa gateway collects the data sent by multiple main control boards and uploads it to the cloud platform through 4G. Factory managers can view and manage the mobile phone quantity information in the turnover box on the platform and evaluate the production capacity of the workshop. When the detection board or the main control board fails, the worker can easily remove it through the adapter board for repair or replacement.
