Detailed Implementation Methods

[0023] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0024] In the description of the embodiments of this application, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0025] Furthermore, if the embodiments of this application involve descriptions such as "first" or "second," such descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.

[0026] In many production and daily life scenarios, people tend to stockpile consumables, such as bottled water, to save time and energy. However, the consumption rate of consumables is unstable, leading to situations such as untimely replenishment and repeated checks of inventory levels, which disrupts the rhythm of production and daily life. Furthermore, the actual inventory of consumables, especially large and heavy items, is also related to the supplier's supply plan and has certain significance for both the production and supply processes of the consumables themselves.

[0027] Based on this, the following embodiments of this application provide a consumable inventory monitoring system.

[0028] Please see Figure 1 , Figure 1 This is a schematic diagram illustrating the configuration of a consumable inventory monitoring system according to an embodiment of this application. The consumable inventory monitoring system 1 is used to monitor the inventory of consumables 2, which can be either industrial or daily consumables. Specifically, they can be bottled, canned, or barrelled consumables such as bottled drinking water, canned compressed gas, or chemical reagents. For hygiene or safety reasons, the consumables 2 are generally not repackaged for storage; instead, the contents are taken directly from their original packaging. Figure 2The three sections (a), (b), and (c) respectively showcase some common consumables. For example... Figure 2 As shown, the consumable 2 typically includes packaging 21 and contents (not shown). The packaging is provided with a grip 211, which is a part that facilitates the application of external force with one hand when picking up the consumable 2.

[0029] The consumable inventory monitoring system 1 includes a consumable inventory detection device 11 and a monitoring platform 13. The consumable inventory detection device 11 communicates with the monitoring platform 13 and is detachably connected to the consumables. In a first state, the consumable inventory detection device 11 is connected to the consumables 2; in a second state, the consumable inventory detection device 11 and the consumables 2 are not connected. When switching from the first state to the second state, the control module of the consumable inventory detection device 11 counts. If the count exceeds a preset threshold, it sends a signal to the monitoring platform 13 as an early warning. After receiving the early warning signal from the consumable inventory detection device 11, the monitoring platform 13 analyzes and statistically processes the location information, historical purchase quantity, historical purchase time, and other information of the consumable inventory detection device. Based on this, it can rationally arrange supply or purchase plans and replenish the inventory of the consumables 2 in a timely manner.

[0030] It is understood that the consumable inventory detection device has an independent identification code (BoradID). After a specific procurement activity is completed, the monitoring platform will collect relevant procurement information based on the identification code, so as to facilitate analysis and statistics after receiving the early warning signal from the inventory detection device 11.

[0031] Specifically, in this embodiment, the grip portion 211 of the consumable 2 is provided with an identification tag (not shown). In a first state, the consumable inventory detection device 11 is engaged and fixed to the grip portion 211 to continuously sense the identification tag; in a second state, the consumable inventory detection device 11 is detached from the grip portion 211, and the identification tag is not sensed. The consumable inventory detection device 11 determines whether it is in the first or second state based on the sensing state of the identification tag, and then counts the inventory. In this embodiment, the identification tag can be an RFID tag; in other embodiments, the identification tag can also be a magnetic tag.

[0032] In other embodiments, the consumable 2 may not have an identification tag. The consumable inventory detection device 11 may also determine whether it is in the first state or the second state through other sensing methods, such as sensing methods based on pressure changes or sensing methods based on light and shadow changes.

[0033] It is understood that the preset threshold is a percentage and can be set based on the total amount of consumables in the same procurement batch. For example, the preset threshold can be set to 10%, 20%, or 50% of the total amount of consumables in the same procurement batch. Of course, other setting methods can also be used, such as using machine learning to obtain the consumption pattern curve of consumables and then dynamically setting the preset threshold.

[0034] The following embodiments of this application provide a consumable inventory detection device.

[0035] Please refer to the following: Figure 3 and Figure 4 , Figure 3 This is a three-dimensional structural diagram of a consumable inventory detection device provided in one embodiment of this application. Figure 4 for Figure 3 The diagram shows an exploded perspective view of the consumable inventory detection device. The consumable inventory detection device 3 includes a main unit 31 and multiple probes 33. Each probe 33 includes a body 331, a sensor switch 333, and a cover 335. The body 331 is detachably connected to the consumable 2, and the body 331 and the cover 335 cooperate to form a receiving cavity 337. The sensor switch 333 is partially housed in the receiving cavity 337 and senses the consumable 2. The main unit 31 includes a counter. The main unit 31 is electrically connected to the probes 33 to receive electrical signals sent to the main unit 31 by the multiple probes 33. The counter counts the number of probes that received electrical signals or the number of probes that did not receive electrical signals, and issues a warning signal when the count exceeds a preset threshold.

[0036] In this embodiment, the example is given with two probes 33. It can be understood that in actual applications, the number of probes 33 is equivalent to the number of consumables 2 in the same procurement batch, and the number of probes 33 is at least two.

[0037] Please refer to the following: Figure 5 , Figure 5 for Figure 3 The schematic diagram shown is a partial three-dimensional structure of the host computer, for ease of explanation. Figure 5The second housing is not shown. The main unit 31 includes a first housing 311, a second housing 313, a control module 315, a battery 317, and an antenna 319. The first housing 311 and the second housing 313 are fixedly connected, for example, by bolts or snap-fit. The first housing 311 and the second housing 313 cooperate to form a receiving space 312, in which the control module 315, the battery 317, and the antenna 319 are housed. The battery 317 and the antenna 319 are electrically connected to the control module 315. The battery 317 supplies power to the control module 315, and the control module 319 controls the antenna 319 to transmit and receive wireless signals to enable communication between the consumable inventory detection device 3 and the monitoring platform.

[0038] To secure the battery 317, the first housing 311 has a first fixing part on the side near the second housing 313, and the second housing 313 has a second fixing part 3131 on the side near the first housing 311. The first fixing part and the second fixing part 3131 are disposed opposite to each other, and the first fixing part and the second fixing part 3131 cooperate to form a fixing groove 314, the inner wall of the fixing groove 314 engaging and securing the battery 317. In this embodiment, the battery 317 is a hard-pack cylindrical lithium battery; in other embodiments, it can also be a hard-pack square lithium battery or a soft-pack battery, etc.

[0039] The control module 315 includes a circuit board 3151, a control chip 3153, a data interface 3155, and a communication unit 3157. The control chip 3153, the data interface 3155, and the communication unit 3157 are electrically connected to the circuit board 3151, for example, by soldering or crimping. The battery 317 and the antenna 319 are electrically connected to the circuit board 3151 via conductors (not shown). The circuit board 3151 is fixedly connected to the first housing 311.

[0040] The first housing 311 has several fixing posts 3111, and the circuit board 3151 has connection holes corresponding to the fixing posts 3111. The circuit board 3151 is sleeved onto the fixing posts 3111 through the connection holes. In this embodiment, the inner wall of the connection hole is coated with adhesive, and the circuit board 3151 is fixedly connected to the first housing 311 by bonding with adhesive. The circuit board 3151 can be a printed circuit board (PCB), and in other embodiments, it can also be a ceramic circuit board.

[0041] The number of data interfaces 3155 corresponds to the number of probes 33. Each data interface 3155 is connected to a probe 33 via a physical dielectric (not shown). The data interface 3155 can be an RS232 interface, RS422 interface, or USB interface, etc. In this embodiment, it is an RS232 interface. The first housing 311 and the second housing 313 also cooperate to form a through hole 316. The through hole 316 connects the receiving space 312 to the external space. The through hole 316 corresponds to the data interface 3155. The physical dielectric connects the data interface 3155 and the probe 33 through the through hole 316, thereby realizing the exchange of electrical signals between the host 31 and the probe 33.

[0042] The communication unit 3157 includes a card slot and card slot pins. The card slot is fixedly connected to the circuit board, for example, by adhesive bonding. The card slot pins are electrically connected to the circuit board 3151, for example, by metal soldering. There are multiple card slot pins, including power supply pins (VCC), ground pins (GND), input / output pins (I / O), card insertion detection pins (CD), and data communication pins (DATA), etc. The definitions of the card slot pins conform to the standards of the International Telecommunication Union (ITU). The communication unit 3157 cooperates with an IoT card plugged into the host 31. The card slot pins are electrically connected to the pins of the IoT card. Through signal exchange between the IoT card and a nearby external base station, the communication unit 3157 achieves geolocation functionality.

[0043] The control chip 3153 may include, or may be one or more combinations of various processors such as a Digital Signal Processor (DSP), a Microcontroller Unit (MCU), and a Central Processing Unit (CPU). In this embodiment, the control chip 3153 may be a single-chip microcomputer. The control chip 3153 includes a clock circuit, which controls the control module 315 to operate intermittently to save energy. The control chip 3153 also includes a counter, which counts the number of probes that receive electrical signals or the number of probes that do not receive electrical signals, and issues a signal as an early warning when the count exceeds a preset threshold.

[0044] It is understood that the control module 315 also includes a charging interface, which is electrically connected to the circuit board 3151. An external power supply is connected to the charging interface to charge the battery 317 and simultaneously power the control module 315. When the external power supply is removed, the battery 317 powers the control module 315 to maintain the normal operation of the consumable inventory detection device 3.

[0045] Please refer to the following: Figure 3 and Figure 6 , Figure 6 for Figure 3 The schematic diagram shown is a partial three-dimensional representation of the probe, intended for ease of illustration. Figure 6 The cover is not shown. The probe 33 includes a main body 331, a sensor switch 333, and a cover 335. The main body 331 and the cover 335 cooperate to form a receiving cavity 337. The sensor switch 333 is partially housed in the receiving cavity 337 and partially exposed through an opening 339.

[0046] The main body 331 includes a wiring portion 3311, a connecting portion 3313, and a locking portion 3315. The wiring portion 3311 and the locking portion 3315 are fixedly connected as an integral structure through the connecting portion 3313. The wiring portion 3311 has a circular structure, the locking portion 3315 has a C-shaped structure, and the connecting portion 3313 connects and transitions the wiring portion 3311 and the locking portion 3315. The wiring portion 3311 and the connecting portion 3313 cooperate with the cover 335 to form the receiving cavity 337. The connecting portion 3311 has an opening 339 on the side near the locking portion 3315. The sensor switch 333 is installed on the inner wall of the receiving cavity 337, for example, by welding or adhesive bonding. The sensor switch 333 is partially exposed through the opening 339.

[0047] The engaging portion 3315 includes two spaced-apart clamping arms 33151. One end of each clamping arm 33151 is fixedly connected to the connecting portion 3313, while the other end is suspended. The engaging portion 3315 is generally C-shaped. In other embodiments, the engaging portion 3315 may also be U-shaped. The opening 339 is located between the two clamping arms 33151. The maximum distance between the two clamping arms 33151 is less than the size of the grip portion of the consumable 2, so that the engaging portion 3315 clamps and fixes the grip portion, and the sensor switch 333 exposed through the opening 339 abuts against the grip portion.

[0048] The main body 331 is made of a lightweight rigid material, such as polypropylene (PP), thermoplastic resin (ABS), polyetheretherketone (PEEK), or carbon fiber, etc. In this embodiment, the wiring part 3311, the connecting part 3313, and the engaging part 3315 are injection molded from carbon fiber material, so that the main body 331 is an integral structure.

[0049] The probe 33 also includes an elastic rib 334, which is located on one side of the two clamping arms 33151 facing away from each other. The extending direction of the elastic rib 334 is consistent with the extending direction of the clamping arms 33151. Since the maximum distance between the two clamping arms 33151 is less than the size of the gripping part of the consumable 2, the engaging part 3315 will undergo a certain deformation during the assembly process of the probe 33 and the consumable 2. The elastic rib 334 can store a certain amount of potential energy through its own elastic deformation, preventing the clamping arms 33151 from undergoing plastic deformation or breakage during the deformation process, thus reducing the assembly difficulty between the probe 33 and the consumable 2. At the same time, the elastic rib 334 can also absorb external vibrations or impacts, maintaining the contact stability between the inductive switch 333 and the gripping part. When purchasing consumables in bulk, the probe can be quickly assembled, and when picking up a particular consumable, the probe can be quickly disassembled.

[0050] The elastic rib 334 is made of a soft, elastic material, such as silicone or rubber. In this embodiment, the elastic rib 334 is integrally formed with the main body 331 through a liquid silicone injection molding process.

[0051] On the side away from the opening 339, the main body 331 is provided with a wiring hole 332, which connects the receiving cavity 337 to the external space. The wiring portion 3311 has a circular structure, and the inner wall of the receiving cavity 337 is provided with multiple protrusions 3371 on two opposite sides of the wiring portion 3311 along the radial direction. The protrusions 3371 are staggered along the tangential direction of the wiring portion 3311. The inductive switch 333 is fixedly connected to the inner wall of the receiving cavity 337, for example, by welding or adhesive bonding. One end of the physical dielectric is connected to the inductive switch 333, and the other end extends through the wiring hole 332 after passing around the protrusions 3371, then enters the receiving space 312 through the through hole 316, and finally is electrically connected to the data interface 3155 to realize the exchange of electrical signals between the host 31 and the probe 33. The arrangement of the protrusions 3371 makes the wiring of the probe 33 neat and easy for later maintenance.

[0052] The inductive switch 333 can be a pressure sensor, a photosensitive sensor, or an RF signal reader, etc. In this embodiment, the inductive switch 333 can be a pressure sensor. When the probe 33 is connected to the consumable 2, the engaging part 3315 clamps and fixes the gripping part, and the inductive switch 333 exposed through the opening 339 abuts against the gripping part. The inductive switch 333 senses the pressure signal and converts it into an electrical signal, which is then sent to the host 31. After the probe 33 is detached from the gripping part, the inductive switch 333 exposed through the opening 339 no longer contacts the gripping part, and the inductive switch 333 can no longer sense the pressure signal and no longer sends an electrical signal to the host 31. The control module 315 of the consumable inventory detection device 3 counts, and if the count exceeds a preset threshold, it sends a wireless signal to the monitoring platform through the antenna 319 as an early warning. Based on the early warning from the monitoring platform, the inventory of the consumable 2 can be replenished in a timely manner without repeated confirmation or manual counting of the consumable inventory, which is convenient and fast.

[0053] Since the probe 33 is electrically connected to the host 31 via the physical dielectric, when the probe 33 is separated from the gripping part, the physical dielectric is subjected to tensile stress for a long time under the influence of the probe 33's own weight, which can easily lead to poor contact. Therefore, the consumable inventory detection device 3 also includes a magnet 35. Please refer to [link to relevant documentation]. Figure 7 , Figure 7 for Figure 3 The diagram shows a cross-sectional view of the consumable inventory detection device. Multiple magnets 35 are respectively installed on the first housing 311 and the main body 331, for example, by adhesive bonding or snap-fit ​​fixing. In the second state, after the probe 33 is separated from the gripping part, the probe 33 is attracted and fixed to the outer surface of the main body 31 by the attraction of opposite poles of the magnets 35, making it convenient to use and neatly stored, thus extending the service life of the consumable inventory detection device 3.

[0054] The above-described embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
