[0024] Furthermore, the RS485 circuit uses SL7550+B5050 to form an RS485 isolated power supply, and cooperates with CA-IS372 to fully isolate the external communication and internal circuit.

[0025] Furthermore, the 24-bit ADC circuit uses CS1237 as a 24-bit ADC chip, with an effective bit of 18.5 bits, and uses MS4553 as an IO level conversion chip.

[0026] Furthermore, the wide-range non-polarity power supply circuit uses MB6S as an input voltage polarity regulator, the input port voltage can be connected arbitrarily, and the input range is 6V to 30V.

[0029] Data collection and management of smart shelves in the field of smart warehousing. Data collection includes weight and quantity.

The product has three external programmable IO ports, an RGB three-color status indicator and a buzzer, an RS485, and a touch display.

[0030] RS485 Circuit

[0031] Smart shelves use highly dense controllers, usually as few as 16 on a shelf, and as many as more than 100. These controllers are densely installed together, which will lead to communication anomalies. This product uses SL7550+B5050 to form an RS485 isolated power supply, and cooperates with CA-IS372 to achieve full isolation between external communication and internal circuits, thereby protecting the internal high-precision ADC and ensuring effective display accuracy.

[0032] 24-bit ADC circuit

[0033] CS1237 is a 24-bit ADC chip with 18.5 effective bits. Because this product has a 2-inch and 3.5-inch touch screen, in order to achieve the best display effect, the main frequency of the MCU must be high enough, and the characteristics of ARM high-frequency products are basically that the working voltage is mostly 3.3V. However, our product uses a strain gauge analog sensor to collect weight, so the higher the sensor working voltage, the better. Therefore, the ADC in this system uses a 5V working voltage and the MCU uses a 3.3V voltage. In order to make the two IO ports more compatible, this product uses MS4553 as an IO level conversion chip to achieve signal connection between two voltage systems.

[0034] Wide range non-polarity power supply

[0035] This product uses MB6S as the input voltage polarity adjustment. The input port voltage can be connected arbitrarily, and the input range is 6V~30V; P2 and P3 are on-site interactive interfaces, installed at both ends of the board. During installation, the interconnection between the two boards can be completed by directly plugging wires at both ends of the board.

[0036] RGB three-color indicator light circuit.

[0037] Used for on-site status indication, insufficient inventory, material picking / replenishing position indication, and material picking / replenishing in progress and completion indication.

[0038] Built-in buzzer circuit

[0039] High-power active buzzer, used for alarm and touch screen operation prompt tone. AS117 back stage C22, C21, C29, C30, C35, C42, C48, C49, C50 are 10uf parallel circuits, which can effectively filter power supply ripple, and the effect is better than a single electrolytic capacitor.

[0040] Three-way expandable isolated IO port

[0041] Three-way expandable IO, using LTV-375 as signal isolation, MMBT5551 as signal amplification, can externally control products with different voltages such as 12V, 24V, etc.

[0042] 2-inch, 3.5-inch screen interface, touch drive circuit, font circuit.

[0043] XPT2046 is a resistive touch screen driver chip, compatible with 2-inch and 3.5-inch screens. GT30L32SW is a font chip, P2 is a display touch screen interface. S8050 is a backlight driver control.

[0044] It should be noted that, in this article, relational terms such as first and second (number one, number two), etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
