[0036] Figure 7 The schematic diagram illustrates the steps of a warehouse communication method according to an embodiment of the present invention. Detailed Implementation

[0037] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of the present invention.

[0038] Figure 1 A schematic diagram illustrating the architecture of a warehouse communication system according to an embodiment of the present invention is shown. Figure 1 As shown, a warehouse communication system includes a mobile human-machine interface (HMI), a signal transmitter, and at least two signal receivers. The mobile HMI is configured to receive a signal receiver ID and operation code input by a user. It can be a common mobile device such as a text input pad or mobile terminal, and has an input function, allowing the user to input the signal receiver ID and operation code. The signal transmitter can connect to the mobile HMI via an interface such as USB, which can be replaced with a common interface such as a serial port. The signal transmitter can send information to the signal receivers on multiple preset communication frequency bands. The signal transmitter is configured to send a wake-up command and an operation command on the communication frequency band corresponding to the signal receiver ID. The wake-up command is used to put the signal receiver in the receiving state on the communication frequency band; the operation command is used to trigger the signal receiver corresponding to the signal receiver ID to execute the operation corresponding to the operation code. The at least two signal receivers are divided into multiple groups, each group receiving the wake-up command and operation command on a configured communication frequency band.

[0039] This implementation uses multiple communication frequency bands, primarily to save power consumption of the receiving terminal. When a signal transmitter on a specified frequency is activated, only the receiving terminal on one frequency band is awakened, preventing receiving terminals on other frequency bands from being awakened, thereby achieving energy savings.

[0040] The following uses the 433 and 315 frequency bands as examples to explain the communication mechanism between the signal transmitter and the signal receiver.

[0041] The total number of signal receivers is determined by the quantity of goods; the number of receivers corresponds to the number of goods. There are two types of receivers: 433 receivers and 315 receivers, with an average allocation of 50 / 50 between the two. After obtaining the receiver ID, the mobile human-machine interface determines whether the receiver operates on the 433 or 315 frequency band, and then calls the corresponding communication module on the transmitter. This method ensures that only one of the 433 or 315 frequency bands is activated, thus reducing the power consumption of receivers that do not require activation.

[0042] The wake-up command corresponds to a timed wake-up mechanism to avoid waking up all signal receivers at once. The wake-up command includes a wake-up code, the length of which can be defined as one byte, ranging from 1 to 250; where 0 and 251-254 are reserved for customization, and 255 wakes up all signal receivers. Each signal receiver corresponds to only one wake-up code; using the maximum distribution algorithm, one-to-one wake-up can be achieved for up to 500 signal receivers. The wake-up duration triggered by the wake-up command is slightly longer than the sleep cycle (+8-16) synchronization codes.

[0043] The operation instructions include an operation code, which is an operation that takes values ​​sequentially from 1 to 9. This is to provide different signal indications for the attached packages, avoiding blind searching by multiple people. When the signal receiver ID and operation code are obtained, they are encapsulated as 91 + operation code + indicator clip ID + CRC and then broadcast.

[0044] In some embodiments of the present invention, the signal receiving end includes: a main control chip; and a power management chip and a receiver chip connected to the main control chip; the receiver chip is used to receive information on a preset communication frequency band; the power supply battery and the solar panel are both connected to the power management chip.

[0045] Figure 2 A schematic diagram illustrating the hardware structure of a signal receiver according to an embodiment of the present invention is shown. Figure 2As shown, the power supply battery is preferably a 3.3V 50-200mA high-density battery, and the solar panel is preferably a 30mm×40mm customized high-efficiency solar panel. The power management chip coordinates and manages the power supplied by the battery and solar panel. The main control chip is connected to this power management chip and the receiver chip. The receiver chip provides the communication circuitry for the communication frequency band and transmits signals outwards through an antenna. This embodiment uses a solar panel to power the receiver, which is maintenance-free for life and requires no battery replacement. The signal receiving end also includes an indicator clip, which includes an indicator light and a buzzer for executing operation codes. For example, the length of the operation code is set to 1B; operation code 01 represents: the light is always on, and the sound is always on; operation code 02 represents: the light is always on, and the sound is short and rapid, etc. The indicator clip is configured with a 4B-length signal receiving end ID for marking the indicator clip, ensuring consistency with the attached barcode.

[0046] Correspondingly, the structure of the signal transmitting end includes: an interface with the mobile human-machine interface, a conversion chip, a main control chip, and a 433 / 315 transmitter chip. The interface with the mobile human-machine interface is preferably a USB interface, and the corresponding conversion chip is a USB-to-serial converter chip.

[0047] In some embodiments of the present invention, the signal receiver is configured to be in one of the states in a preset set of states; the states in the preset set of states include: sleep state, standby state, receiving state, processing state, and other states.

[0048] Figure 3 A schematic diagram illustrating the state transition of a signal receiver according to an embodiment of the present invention is shown. Figure 3 As shown, the various states in the preset state set are explained below: Sleep state is the most power-efficient state, where only the timer is active. When the timer expires, the receiver enters standby state. After receiving a wake-up code from the transmitter, it enters receiving state. To ensure all receivers on the specified frequency (433 or 315) enter receiving state, the transmitter continuously sends wake-up codes. Once all receivers on the specified frequency (433 or 315) are awakened, the transmitter sends a command. The machine receiving the command enters processing state, and after processing, enters the successful pickup state (subsequent software state machine). Non-local commands or erroneous data will return to sleep state. Through these state settings, the signal receiver can accurately respond to and present the current indication information.

[0049] In some embodiments of the present invention, the signal receiving end is configured to communicate in one of the following ways: fixed channel mode and frequency modulation communication mode.

[0050] Figure 4 A schematic diagram illustrating the time slot relationship of a fixed channel method according to an embodiment of the present invention is shown. Figure 4As shown, the fixed channel method includes: opening a receiving window on a fixed channel for receiving messages during each sleep cycle; the signal receiver operates by opening a narrow receiving window on a fixed channel during each sleep cycle (temporarily set to 3s in this embodiment). As mentioned above, in this embodiment, the transmission time of a single message frame sent by the PAD transmitter is 125us. Theoretically, opening a 250us window is sufficient to receive a complete message frame. Setting it to 1ms provides a certain degree of redundancy and anti-interference capability. When the transmitter sends a message to the signal receiver, it needs to continuously send the same message on the fixed channel for more than 3 seconds (e.g., 4 seconds) so that the signal receiver can receive the transmitter's message within the receiving window.

[0051] Figure 5 A schematic diagram illustrating the time slot relationship of a frequency modulation communication method according to an embodiment of the present invention is shown. Figure 5 As shown, the frequency hopping communication process involves sequentially opening receiving windows on several frequency points during each sleep cycle to receive messages. To cope with co-channel interference from other 2.4G devices, the PAD transmitter and signal receiver employ frequency hopping communication; for example... Figure 5 As shown, the receiver opens each receiving window for 3ms, and activates the receiver for 1ms on channels 0, 9, and 19 respectively. When the transmitter sends a message to the receiver, it needs to continuously send the same message on channels 0, 9, and 19 for a period of more than 3 seconds (e.g., 4 seconds). If the receiver is interfered with on two of the channels, it can receive the message through the other channel.

[0052] In some embodiments of the present invention, the signal receiver is configured to: parse the signal receiver ID in the message; compare the parsed signal receiver ID with its own ID; if they are the same, perform the operation corresponding to the opcode; if they are different, discard the message and enter a sleep state.

[0053] Specifically, the communication process with the target signal receiver is as follows: The transmitter continuously sends messages on channels 0, 9, and 19 for 4 seconds. After opening its reception window, the signal receiver receives a message from channel 0 within a maximum of 4 × 125 µs. After receiving the message, it checks the address and finds that it is a message destined for itself, then executes the operation corresponding to the opcode, such as turning on an LED or buzzer. Similarly, the transmitter's continuous 4-second message transmission on channels 0, 9, and 19 will reach other signal receivers. After opening its reception window, the signal receiver receives a message from channel 0 within a maximum of 4 × 125 µs. After receiving the message, it checks the address and finds that it is not a message destined for itself, then discards the message and enters a sleep state. In some abnormal situations, assuming channel 0 is interfered with, the signal receiver receives messages on channel 0 for 1 ms without receiving a message. Then, it sets the channel to 9 and receives messages for 1 ms. The transmitter still sends messages sequentially on channels 0, 9, and 19. When it sends messages on channel 9, the signal receiver will receive the message.

[0054] In some embodiments of the present invention, the message adopts a header plus payload format, wherein the payload includes the signal receiver ID and the opcode.

[0055] Figure 6 A schematic diagram illustrating a message structure according to an embodiment of the present invention is shown. Figure 6 As shown, the total length of the message sent by the PAD transmitter is 16 bytes, corresponding to an air transmission time of 125µs. This duration is estimated based on a physical layer transmission rate of 1Mbps. The message structure includes a preamble, a header delimiter (SFD), a payload, and a checksum (CRC). The payload includes a header, an opcode, a receiver ID, and a CRC checksum. The physical layer for message transmission uses the 2360MHz–2400MHz frequency band, with 20 channels per 2MHz channel. In this embodiment, frequency hopping communication uses channels 0, 9, and 19 as the communication frequencies for the mobile human-machine interface and the receiver, providing excellent anti-interference capabilities.

[0056] Based on the same inventive concept, the present invention also provides a warehouse communication method for use in a warehouse communication system, the system comprising a mobile human-machine interface terminal, a signal transmitter, and at least two signal receivers.

[0063] In some optional implementations, a wake-up command is used to put the signal receiver in the communication band into a receiving state, including: broadcasting the wake-up command on the communication band, and the signal receiver in the standby state changing from the standby state to the receiving state; the signal receiver is configured to change from a sleep state to a standby state at regular intervals, and change to a sleep state after not receiving a wake-up command during the standby state duration.
