However, during signal transmission, important control signals and monitoring signals simultaneously occupy limited bandwidth, prolonging the system response time and compromising reliability. As a result, in actual debugging, there are situations where the response of start / stop and emergency stop signals is prolonged during operation, making it impossible to smoothly control the target.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] The inspection robot is equipped with a PLC control system to control its drive, battery, safety, and process. This allows for comprehensive local control of the robot. However, the robot needs to communicate with a remote supervisory control system during operation. Due to process limitations, this is typically achieved via wireless Ethernet. The supervisory control system sends start / stop and emergency stop signals, while simultaneously transmitting data such as speed, current, torque, and scan results in real time. During signal transmission, both critical control and monitoring signals consume limited bandwidth, extending system response time and compromising reliability. This can lead to situations during actual commissioning where start / stop and emergency stop signal responses are delayed, hindering successful target control. Furthermore, adjusting the Ethernet transmission cycle can result in network congestion or excessively long data acquisition periods, reducing data availability.

[0023] Please see Figure 1 One embodiment of this application provides a remote monitoring method applied to a server, the server being connected to an inspection robot, and the method may include the following multiple steps.

[0024] S110: Divide multiple control signals and multiple monitoring signals into different levels; the control signals are used to instruct the operation of the inspection robot; the monitoring signals are used to monitor the status of the inspection robot.

[0025] In this embodiment, control signals and monitoring signals in the control system, including the server and the inspection robot, are classified according to their importance. Then, the transmission time interval for each level of signal is determined based on the importance of the signal and the timeliness requirements of its transmission. Specifically, for example, critical control signals are classified as level 0, important information in the monitoring signals is classified as level 1, and other monitoring signals are classified as level 2. Level 0 critical control signals are sent remotely to the inspection robot by the server in the control system at irregular intervals, including start control signals and emergency stop control signals. Level 1 important monitoring signals are sent by the inspection robot to the remote server at regular intervals, including encoder data, gyroscope tilt angle X and Y data, motor speed, torque, current, and feedback from the inspection robot's operating status. This data is packaged into a level 1 feedback data array in the inspection robot's PLC control system. Level 2 other monitoring signals are sent by the inspection robot to the remote server at longer intervals, including: inspection robot battery level, control room temperature and humidity, inspection robot mileage, number of runs, fault codes, and historical fault codes. This data is packaged into a Level 2 feedback data array in the inspection robot PLC control system.

[0026] S120: Establish the connection relationship between the server and the inspection robot for the multiple control signals and multiple monitoring signals, and generate connection identifiers for each control signal and each monitoring signal.

[0027] In the control system, SOCKET connections are established between the server and the inspection robot for each control and monitoring signal. After acquiring the handle, the signal transmission rate can be controlled via pulse quantities. Specifically, for example, a TCP / IP SOCKET server is established in the inspection robot's PLC control system, while a TCP / IP SOCKET connection is established in the remote host system. The server establishes a server, acquires the port, and enters listening mode, waiting for the inspection robot to initiate a connection. Upon receiving a connection request, it establishes a communication handle and completes the connection task.

[0028] S130: Determine the transmission time interval of control signals / monitoring signals represented by different connection identifiers; the transmission time interval of control signals / monitoring signals is different for different levels.

[0029] In this embodiment, after the connection is established, the server can use its receiving function to read start and emergency stop signals sent by the client at the specified IP address. The received signal is read from the receive buffer every 100ms according to the program scan cycle in the PLC control system. The high refresh rate ensures that the target information is received in the shortest possible time, guaranteeing the highest priority transmission of control signals. For Level 1 monitoring signals, data can be sent at a base cycle of 1 second (i.e., time interval), and for Level 2 monitoring signals, data can be sent at a base cycle of 1 minute (i.e., time interval).

[0030] S140: Send the control signal to the inspection robot according to the transmission time interval corresponding to the connection identifier, and receive the monitoring signal fed back by the inspection robot according to the transmission time interval corresponding to the connection identifier.

[0031] In this embodiment, by establishing the aforementioned connection, after the connection is established, the server can use its sending function to transmit a specified array or data to the inspection robot through a specific port, thereby controlling the inspection robot. The server can also use its receiving function to receive monitoring signals fed back by the inspection robot through a specified array or data via a specific port. Specifically, for example, the control signal is a start signal, which is sent to the inspection robot at a transmission period of 100ms, thereby controlling the operation of the inspection robot. The monitoring signal is the motor speed, which is fed back to the server at a transmission period of 1s.

[0032] In one embodiment, the remote monitoring method may further include: receiving a monitoring signal sent by the inspection robot when the status information of the inspection robot changes.

[0033] In this embodiment, since the amount of data to be sent is large and data transmission is not required periodically when the device is in standby mode, an event-driven approach is adopted to initiate data transmission. That is, data transmission only occurs when the data changes. In most cases, the device is in standby mode, most of the data remains unchanged, and no data transmission occurs. This can effectively reduce the bandwidth usage.

[0034] In one embodiment, the status information of the monitoring signal is represented by a binary value, and the remote monitoring method may further include: if the last bit of the status information of two consecutive monitoring signals is different, receiving the monitoring signal sent by the inspection robot.

[0035] In this embodiment, in the PLC control system of the inspection robot, the last bit of all real-time binary values ​​of the Level 1 and Level 2 signals are XORed, and their transition edges are captured in real time. Once a transition occurs, it is considered that the signal has changed, and the basic cycle (1 second) of the sending command is invoked based on this event. This realizes the event-driven cycle calling. The basic cycle ensures that the sending module is not called too frequently, while the event-driven approach ensures that no data is sent when there is no change. When the signal changes, the Level 1 signal is sent in a 1-second cycle using the event-driven approach, and the Level 2 signal is sent in a 1-minute cycle. In this way, the highest priority call for receiving control signals can be achieved, and the buffer is read once every 100ms. When the sent status signal changes, data such as current is recorded in a 1-second cycle, and feedback of slowly changing signals such as battery level, temperature, and humidity is completed in a 1-minute cycle. When the signal to be sent does not change, it basically does not occupy wireless communication bandwidth. This can effectively reduce the amount of wireless communication data and realize signal transmission according to priority.

[0036] In one embodiment, the plurality of control signals and the plurality of monitoring signals are divided into three levels; the three levels may include high-level signals, medium-level signals, and low-level signals; the high-level signals include at least one of the following: a start control signal; an emergency stop control signal; the medium-level signals include at least one of the following: an encoder data monitoring signal, a gyroscope tilt angle X monitoring signal, a gyroscope tilt angle Y monitoring signal, a motor speed monitoring signal, a torque monitoring signal, a current monitoring signal, and an inspection robot operating status monitoring signal; the low-level signals include at least one of the following: a temperature monitoring signal, a humidity monitoring signal, an inspection robot mileage monitoring signal, an inspection robot operation count monitoring signal, an inspection robot fault code monitoring signal, and an inspection robot historical fault code monitoring signal.

[0037] In this embodiment, control signals and / or monitoring signals are classified according to their importance or required response speed. Data of each level is packaged into a single data packet for signal transmission. Signals of the same level can be transmitted at the same transmission time interval to avoid data transmission disorder.

[0038] In one embodiment, the transmission time interval of the high-level signal may be less than or equal to the transmission time interval of the medium-level signal; the transmission time interval of the medium-level signal may be less than or equal to the transmission time interval of the low-level signal. It should be noted that the embodiments described in this specification do not limit the classification of signals; the above only refers to the categories of signals. Control signals can also be scanner start signals or scanner end signals, which can be classified as medium-level signals.

[0039] In this implementation, for high-level signals, due to their importance, the transmission time interval needs to be as short as possible. For low-level signals, since the timeliness requirement for data acquisition is not high, they can be acquired once every 1 minute. However, for signals such as the start signal and emergency stop signal of the inspection robot, which have higher timeliness requirements, they need to be set to be sent once every 100ms.
