A handheld debugging device for terminal control equipment

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This disclosure claims priority to Chinese patent application number 2024202538319, filed with the Chinese Patent Office on January 31, 2024, entitled “A handheld debugging device for terminal control equipment,” the entire contents of which are incorporated by reference into this disclosure. Technical Field

[0003] The present disclosure belongs to the field of handheld debugging devices, and in particular relates to a handheld debugging device for terminal control equipment. Background Art

[0004] The statements in this section merely provide technical information related to the present disclosure and do not necessarily constitute prior art.

[0005] In recent years, with the continuous development of science and technology and the rapid growth of the logistics industry, factory warehouse management has gradually developed in the direction of automation, scientificization, and intelligence. Intelligent warehousing technology integrates automated equipment, Internet of Things technology, artificial intelligence algorithms, and big data analysis to achieve rapid, accurate, and efficient storage, picking, and distribution of materials within the warehouse, thereby improving overall warehouse operation efficiency. Automated shelving and storage location management, as one of the intelligent warehousing technologies, effectively avoids the time-consuming and error-prone manual operation process compared to traditional warehouse management that relies on manual operations such as goods entry, shelving, de-shelving, and transfer. It can achieve real-time monitoring of goods, automated positioning, and intelligent storage and picking, thereby improving warehousing efficiency.

[0006] Automated shelving and storage location management typically involves connecting intelligent shelves to terminal control devices via cables. Traditional terminal control devices are equipped with a dialer to set the terminal control device's communication address. However, since each terminal control device requires a dialer, the dialers on the terminal control devices are gradually being eliminated due to manufacturing cost considerations. Instead, the terminal control devices are connected to a host computer via cables. After the host computer sets up and debugs the terminal control device, the terminal control device controls the rotation and movement of the shelf, thereby achieving intelligent and automated control of the shelf. Debugging the terminal device with the host computer is a prerequisite for ensuring the control of automated shelves. Currently, host computers are usually large devices such as computers. These are inflexible and non-portable during the debugging process, which to a certain extent affects the ease of use for on-site debugging by debugging personnel.

[0044] It should be noted that the following detailed descriptions are illustrative and intended to provide further explanation of the present disclosure. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which the present disclosure belongs.

[0045] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present disclosure. As used herein, unless the context clearly indicates otherwise, the singular form is intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, they indicate the presence of features, steps, operations, devices, components and / or combinations thereof.

[0046] One or more embodiments provide a handheld debugging device for a terminal control device. The device includes a main control chip, a signal input circuit, a communication circuit, and a power supply circuit. The signal input circuit is connected to the main control chip and configured to output an enable signal corresponding to a debugging control instruction to the main control chip. The main control chip is connected to the terminal control device via the communication circuit, and the main chip is configured to output the enabled debugging control instruction and transmit it to the terminal control device via the communication circuit. The power supply circuit is configured to supply power to other circuits in the handheld debugging device. The communication circuit in this embodiment is a CAN communication circuit.

[0047] It should be noted here that, in other embodiments, those skilled in the art may set the specific structure and form of the communication circuit according to actual conditions.

[0048] In this embodiment, the power supply circuit includes a power input interface and a step-down circuit. The power input interface and the step-down circuit are electrically connected. The power input interface is electrically connected to the CAN communication circuit. The step-down circuit is electrically connected to the main control chip and the signal input circuit.

[0049] Specifically, according to Figure 2, the power input interface includes a Type-C interface and a Type-C interface chip. The external DC power supply is connected to the Type-C interface chip through the Type-C interface. The Type-C interface chip outputs a first positive voltage (such as +5V voltage). The output first positive voltage is used to power the CAN communication circuit, and the step-down circuit outputs a second positive voltage (such as +3.3V voltage) to power the main control chip and the signal input circuit.

[0050] Optionally, the power supply circuit can also be configured to include a built-in battery and a step-down circuit, the built-in battery and the step-down circuit are electrically connected, the power input interface is electrically connected to the CAN communication circuit, and the step-down circuit is electrically connected to the main control chip and the signal input circuit.

[0051] As shown in Figure 3, the Type-C interface chip uses a USB-C interface chip. The A5 and B5 pins (i.e., function pins CC1 and CC2) of the interface chip are connected to resistors R3 and R1, respectively, and then to ground. The GND pin of the interface chip is grounded. The A4 pin (i.e., function pin VBUS) of the interface chip outputs a +5V voltage and is connected to capacitor C8 and then to ground. In addition, the S1 pin (i.e., function pin SHIELD) of the interface chip is connected in parallel to resistor R15 and capacitor C22, and then to ground.

[0052] In this embodiment, the +5V voltage output by the Type-C interface chip is input to the step-down circuit. As shown in FIG4 , the step-down circuit includes a voltage regulator chip. In this embodiment, a voltage regulator chip model AMS1117 is used. The VI input pin of the voltage regulator chip is connected to the fuse F1 and then connected to the +5V voltage. At the same time, the VI input pin is connected to the capacitor C14 and then grounded. The VO output pin of the voltage regulator chip is respectively connected in parallel to the capacitor C15, the capacitor C16, the light-emitting diode and the resistor R8 in series and then grounded. The VO output pin outputs a +3.3V voltage. The GND ground pin of the voltage regulator chip is grounded.

[0053] As shown in Figure 2, the power supply circuit also includes a power output circuit, which is configured to power the terminal control device. The power output circuit includes a power output interface and a voltage regulator circuit. The input end of the voltage regulator circuit is electrically connected to the voltage output end of the Type-C interface chip, and the output end of the voltage regulator circuit is electrically connected to the power output interface. For example, the +5V voltage output by the Type-C interface chip is input to the voltage regulator circuit, and the voltage regulator circuit outputs a +24V voltage, which is then used to power the terminal control device through the power output interface.

[0054] In this embodiment, the +5V voltage output by the Type-C interface chip is also input into the voltage regulation circuit.

The +VIN pin of the isolated power supply module is connected to the +5V voltage, and the +VIN pin is connected to the -VIN pin through a capacitor C12 and then grounded; the +VOUT pin and -VOUT pin of the isolated power supply module are connected to the power output interface.

[0055] Through this connection method, an external DC power supply is connected to the Type-C interface. The Type-C interface chip outputs a +5V voltage. The step-down circuit steps down the +5V voltage to +3.3V, which powers the main control chip and signal input circuit in the device. The voltage regulation circuit regulates the +5V voltage to +24V. When testing the control card in the terminal control device separately, the power output interface can be used to connect the control card in the terminal control device to power the control card. When the terminal control device is installed on the production line, the control card no longer needs to be connected to the power output interface and can rely on the bus for power supply.

This termination resistor is configured to balance the transmission line impedance, absorb signal reflections and callbacks, and improve the anti-interference capability and reliability of data communication. The VCC pin of the CAN processing chip is connected to +5V and connected to capacitors C2 and C3 in parallel before being grounded. The TXD and RXD pins of the CAN processing chip are electrically connected to the PA12 and PA11 pins of the main control chip, respectively, through an intermediate transceiver circuit. Through the above-mentioned CAN communication circuit, CAN signals are transmitted to the main control chip, and after being connected to an external terminal control device, communication with the terminal control device can be achieved.
