Description

Technical Field

[0001] The present invention relates to the technical field of robot ultrasonic transceiver systems, and in particular to an ultrasonic communication module applied to a swimming pool robot or a lawn mowing robot. Background Art

[0002] In the prior art, swimming pool robots are generally connected in a wired manner. Specifically, a communication link is established between the underwater robot and the surface base station (including a fixed base station and a floating base station) with the help of a wired cable. Although this connection mode realizes the information interaction between the underwater robot and the control end to a certain extent, it makes the operation and monitoring of the underwater robot possible. However, it cannot be ignored that due to the strict restrictions on the length of the cable or optical cable, the underwater robot's actions are greatly restricted. Once the effective length range of the cable is exceeded, the robot cannot work normally or maintain stable communication with the control end, which seriously restricts its range of activities and work efficiency in waters such as swimming pools. At the same time, wired connections are also prone to problems such as cable damage and entanglement, which undoubtedly increases maintenance costs and the probability of failure. In addition, in actual application scenarios, the presence of cables may also have adverse effects on the swimming pool environment or other work scenarios, such as affecting the aesthetics and hindering the normal operation of other equipment.

[0003] On the other hand, in the field of lawn mowing robots, existing technologies usually use complex and expensive RTK modules (real-time dynamic measurement and positioning technology). Although this module has certain advantages in positioning accuracy, its complex structure and high cost bring many challenges to the production and application of lawn mowing robots. First, the complex RTK module requires a high level of technology for installation and debugging, which increases the difficulty and time cost in the production process. Secondly, its expensive price has greatly increased the overall cost of lawn mowing robots, limiting the popularity and promotion of the product in the market. In addition, the RTK module may also be affected by environmental factors during actual use, such as signal interference, which affects the accuracy and stability of its positioning.

[0004] In summary, the current wired connection method of swimming pool robots and the existing complex and expensive RTK modules of lawn mower robots have obvious shortcomings, which seriously limit the performance and application scope of underwater robots and lawn mower robots. Therefore, a new technical solution is urgently needed to solve the communication and action limitations of underwater robots, and at the same time provide a simpler, economical and reliable positioning technology for lawn mower robots, so as to improve the working efficiency and reliability of underwater equipment such as swimming pool robots and lawn mower robots, and meet the needs of the market and users. Summary of the invention

[0005] The purpose of the present invention is to solve the shortcomings existing in the prior art, and to propose an ultrasonic communication module applied to a swimming pool robot or a lawn mowing robot. Through the ultrasonic transceiver module, the signal can be transmitted to the signal base station or the robot more accurately and quickly without the need for cable connection, thereby enabling long-distance signal transmission, reducing restrictions on the equipment, and reducing the production cost of the robot.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] An ultrasonic communication module applied to a swimming pool robot or a lawn mowing robot comprises an ultrasonic signal generating / receiving / processing unit, an ultrasonic signal transceiving switching control unit, an ultrasonic modulation signal driving unit, an ultrasonic signal receiving and processing unit and an ultrasonic transceiver. Two of the ultrasonic signal generating / receiving / processing units, the ultrasonic signal transceiving and switching control unit, the ultrasonic modulation signal driving unit, the ultrasonic signal receiving and processing unit and the ultrasonic transceiver constitute a group of ultrasonic wireless communication modules. The output port of the ultrasonic signal generating / receiving / processing unit is connected to the input port of the ultrasonic signal transceiving and switching control unit, the input port of the ultrasonic signal generating / receiving / processing unit is connected to the output port of the ultrasonic signal transceiving and switching control unit, the output port of the ultrasonic signal transceiving and switching control unit is connected to the input port of the ultrasonic modulation signal driving unit, the input port of the ultrasonic signal transceiving and switching control unit is connected to the output port of the ultrasonic signal receiving and processing unit, the output port of the ultrasonic modulation signal driving unit is connected to the input port of the ultrasonic transceiver, and the output port of the ultrasonic transceiver is connected to the input port of the ultrasonic signal receiving and processing unit.

[0008] Preferably, the ultrasonic signal generating / receiving / processing unit is used to process the signal and then send or receive the processed signal.

[0009] Preferably, the ultrasonic signal transceiver switching control unit is used to control the reception or transmission of ultrasonic waves, and the ultrasonic signal generating / receiving / processing unit can control the switching of the ultrasonic signal transceiver switching control unit.

[0010] Preferably, the ultrasonic modulation signal driving unit is used to amplify the processed signal and then send the amplified signal through the ultrasonic transceiver.

[0011] Preferably, the ultrasonic signal receiving and processing unit is used to filter, amplify and demodulate the received signal.

[0012] Preferably, the ultrasonic transceiver includes an ultrasonic transceiver A and an ultrasonic transceiver B, and the signal between the ultrasonic transceiver A and the ultrasonic transceiver B can perform ultrasonic wireless communication.

[0013] Preferably, both the ultrasonic transceiver A and the ultrasonic transceiver B are preset with unique ID information.

[0014] The present invention has the following beneficial effects:

[0015] 1. Compared with the existing technology, the ultrasonic wireless communication module can achieve effective penetration within a short distance, and can maintain communication stability even in different transmission media and with many obstacles, so that the base station signal can be stably transmitted to the robot or the robot signal can be stably transmitted to the base station. The ultrasonic wireless communication module is used to control the robot, which can reduce the power consumption of the robot, and at the same time make the robot smaller and have a higher energy conversion rate.

[0016] 2. Compared with the existing technology, the use of wireless communication technology to control the robot is more efficient than using cables to transmit signals to the robot, and can reduce restrictions on the robot. At the same time, it can replace the complex and expensive RTK module in the lawn mowing robot, reducing the production cost of the lawn mowing robot;

[0017] 3. Compared with the existing technology, the robot is controlled by an ultrasonic wireless communication module, which has stronger penetration ability and can penetrate solids, liquids or gases. At the same time, it has good anti-interference performance, so that the signal can be transmitted completely, and the speed is faster than that of signal transmission using cables, making the robot more responsive. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] Figure 1 This is a block diagram of a signal transmission processing system in an ultrasonic communication module applied to a swimming pool robot or a lawn mowing robot proposed by the present invention. DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0020] Reference Figure 1, an ultrasonic communication module applied to a swimming pool robot or a lawn mowing robot, comprising an ultrasonic signal generating / receiving / processing unit, an ultrasonic signal transceiving switching control unit, an ultrasonic modulation signal driving unit, an ultrasonic signal receiving and processing unit and an ultrasonic transceiver, two ultrasonic signal generating / receiving / processing units, ultrasonic signal transceiving and switching control unit, ultrasonic modulation signal driving unit, ultrasonic signal receiving and processing unit and ultrasonic transceiver constitute a group of ultrasonic wireless communication modules, the output port of the ultrasonic signal generating / receiving / processing unit is connected to the input port of the ultrasonic signal transceiving and switching control unit, the input port of the ultrasonic signal generating / receiving / processing unit is connected to the output port of the ultrasonic signal transceiving and switching control unit, the output port of the ultrasonic signal transceiving and switching control unit is connected to the input port of the ultrasonic modulation signal driving unit, the input port of the ultrasonic signal transceiving and switching control unit is connected to the output port of the ultrasonic signal receiving and processing unit, the output port of the ultrasonic modulation signal driving unit is connected to the input port of the ultrasonic transceiver, and the output port of the ultrasonic transceiver is connected to the input port of the ultrasonic signal receiving and processing unit.

[0021] Among them, the ultrasonic signal generation / reception / processing unit is used to process other signals, generate ultrasonic signals, or convert ultrasonic signals into other signals, and then send or receive ultrasonic signals. The ultrasonic signal transceiver switching control unit is used to control the reception or transmission of ultrasonic waves. The ultrasonic signal generation / reception / processing unit can control the switching of the ultrasonic signal transceiver switching control unit. The ultrasonic modulation signal driving unit is used to amplify the processed signal and then send the amplified signal through the ultrasonic transceiver. The ultrasonic signal receiving and processing unit is used to filter, amplify and demodulate the received signal. The ultrasonic transceiver includes an ultrasonic transceiver A and an ultrasonic transceiver B. The signal between the ultrasonic transceiver A and the ultrasonic transceiver B can perform ultrasonic wireless communication. The communication has CRC check and frame sequence number. When an error occurs, the host is not responded. The host will retransmit the corresponding message after waiting for a timeout. The ultrasonic transceiver A and the ultrasonic transceiver B are preset with unique ID information. For example, the ID information module in the ultrasonic transceiver A can be named UCM_0A, and the ID information in the ultrasonic transceiver B can be named UCM_0B. The numbers will be written in advance when the products are shipped so that they can recognize each other and find the corresponding devices within the coverage range.

[0022] Each ultrasonic transceiver can be configured as a master or a slave. The slave can only send data to respond to the master after receiving the master message. The host can change the role of the slave through the relevant message. Each ultrasonic transceiver has an additional serial port, through which the ultrasonic communication is transparently transmitted.

[0023] It should be noted that when ultrasonic transceiver A is the transmitter, it first broadcasts a signal to search for ultrasonic transceiver B (UCM_0B) in the coverage area. If found, it attempts to establish a connection. After the connection is successfully established, data information transmission interaction begins. The ultrasonic transceiver can also initiate data signal transmission to ultrasonic transceiver A. When one of the ultrasonic transceivers is shielded or exceeds the signal coverage area, the connection will be interrupted and a connection request needs to be re-initiated to establish the connection.

[0024] The present invention can explain its functional principle through the following operation mode: when the ultrasonic transceiver A is installed on the swimming pool robot, the ultrasonic transceiver B is installed on the water surface base station. At this time, the swimming pool robot processes the information that needs to be interacted (including positioning information, control information, status information, etc.) through the ultrasonic signal generation / reception / processing unit and then sends it. At the same time, the ultrasonic signal generation / reception / processing unit will control the ultrasonic signal transmission and reception switching control unit to send the signal according to the signal. After being amplified by the ultrasonic modulation signal driving unit, it is then sent out through the ultrasonic transceiver A. When the ultrasonic transceiver B receives the signal, the received signal is sent through the ultrasonic signal receiving unit. The processing unit filters the redundant clutter in the signal, amplifies and demodulates it, and then transmits it to the ultrasonic signal transceiver switching control unit, and then receives and processes the signal through the ultrasonic signal generation / reception / processing unit, and transmits the processed signal to the terminal device or the shore-based command center after relaying, so as to obtain underwater information in real time to enhance the accuracy, timeliness and effectiveness of information communication. When the robot needs to be controlled, the signal is input to the surface base station, and after processing, it is sent out through the ultrasonic transceiver B. When the ultrasonic transceiver A receives the signal, it will process the signal and then transmit it to the terminal device of the swimming pool robot, so that the swimming pool robot performs the corresponding action;

[0025] When ultrasonic transceiver A is installed on the lawn mower robot, ultrasonic transceiver B is installed on the charging base station. The lawn mower robot transmits the collected information (including positioning information, control information, status information, etc.) to the charging base station in real time, and then transmits it to the terminal device or the remote command center through the charging base station relay, so as to obtain the information of the lawn mower robot in real time and control the lawn mower robot in real time. If the lawn mower robot needs to be controlled, the remote end sends the control command to the lawn mower robot through the base station relay, and the lawn mower robot performs the corresponding action according to the received control command.

[0026] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
