Description

Technical Field

[0001] This application relates to the field of communication technology, and in particular to a network communication connection method, system and device based on TCP / UDP. Background Technology

[0002] There are many communication protocols between devices, but TCP / UDP network communication protocols are still the mainstream. However, many central control systems on the market add one or more relay devices to control terminals that only accept TCP / UDP network communication protocols. These relay devices convert serial port protocols or other protocols to TCP / UDP network communication protocols to control the terminals. Therefore, existing technologies have the following problems: 1) The need to add relay devices increases equipment costs; 2) Initial system setup is cumbersome, increasing debugging costs; 3) Subsequent system maintenance is difficult, increasing maintenance costs. Summary of the Invention

[0027] Another aspect of this application provides a network communication connection system based on TCP / UDP, including: a PC host, a central control host, and one or more terminals;

[0028] The PC host is connected to the central control host via a network, and the central control host is connected to each of the terminals via a network cable.

[0029] The PC host is used to generate configuration files and / or trigger commands in response to user operations, and upload the configuration files and / or trigger commands to the central control host;

[0057] Reference Figure 1 This application provides a network communication connection method based on TCP / UDP, which can be applied to a central control host. The method includes steps S100 to S130, as follows:

[0058] S100: Obtain the configuration file, which includes configuration information for one or more terminals and control commands for the terminals.

[0059] Specifically, the configuration file in this embodiment can be an XML file, i.e., an XML configuration file. The configuration information in the file can include the IP address and port number of each terminal. The purpose of the configuration information is that when the embedded software module of the TCP / UDP network communication protocol creates a socket connection with the terminal, it needs to bind the IP address and port number of the terminal and transmit data to the terminal through the socket file descriptor.

[0060] The specific control commands can perform depend on the type of device the terminal is. For example, if the terminal controls the motor of a curtain, the control commands can control the motor's operation to open, close, or stop the curtains. For example, if the terminal is a host computer controlling lights, the control commands can control the lights to turn on, off, or flash. For example, if the terminal is a camera device, the control commands can control the camera's movement (up, down, left, right), zoom in, zoom out, and return to a preset point.

[0061] As a further implementation, step S100 may include:

[0062] Receive configuration files uploaded by users via PC hosts.

[0063] Specifically, users can configure the configuration file on the logic editing software of the PC host, and then the PC host will upload the configuration file to the central control host.

[0064] S110: Parse the configuration information in the configuration file to obtain the IP address and port number of the terminal.

[0065] Specifically, in this embodiment, the configuration information in the XML format configuration file is parsed to obtain the IP address and port number of each terminal contained in the configuration information.

[0066] Furthermore, the configuration file in this embodiment may also include a single-step command module, a combined command module, a distributed sub-board configuration parameter module, a timed point configuration module, and a keyword matching configuration module.

[0067] Therefore, in this embodiment, parsing the configuration file may further include steps S111 to S114:

[0068] S111: Use the configuration file as the current configuration file and read the version number of the current configuration file.

[0069] Specifically, the central control unit can open the XML format configuration file in read-only mode and read the version number of the newly uploaded XML configuration file.

[0070] S112: If the version number of the current configuration file is higher than the version number of the existing configuration file, then clear the memory linked list container.

[0071] Specifically, the central control unit can determine whether the version number is higher than the version number of the old XML configuration file. If so, it parses the current configuration file and clears the memory linked list container to prepare for storing data from each module; otherwise, it does not parse the current configuration file.

[0072] S113: Read the root node of the current configuration file and read each child node under each root node in a loop to obtain multiple single-step commands, multiple combined commands, multiple distributed sub-board configuration parameters, multiple time point configuration parameters, and multiple keyword matching configuration parameters.

[0073] Specifically, the root node of the XML configuration file is read, which is the entry point for reading all data. Then, each child node under the root node is read in a loop. Each child node is the entry point for reading parameter module data. Reading the child nodes of the child nodes in a loop is equivalent to reading single-step commands, combined commands, sub-board configuration parameters, timer configuration parameters, and keyword matching configuration parameters.

[0074] S114: The multiple single-step commands, multiple combined commands, multiple distributed sub-board configuration parameters, multiple time point configuration parameters, and multiple keyword matching configuration parameters are classified and stored in the memory linked list container for later invocation.

[0075] Specifically, the data read in step S113 is categorized and stored in a memory linked list container to await invocation. Then, the XML configuration file is closed, and the parsing step is exited.

[0076] S120: Establish TCP / UDP network communication with the terminal using the IP address and port number.

[0077] Specifically, in this embodiment, the central control host and the terminal are connected via a network cable. The central control host can quickly create TCP / UDP network communication with the terminal based on the IP address and port number provided in the configuration file.

[0078] As a further implementation, step S120 may include steps S121 to S125:

[0079] S121: Create a socket file descriptor for a TCP / UDP network.

[0080] Specifically, the central control host creates a socket file descriptor for the TCP / UDP network. This socket file descriptor is crucial for the central control host to receive and send data after establishing a connection with the terminal.

[0081] S122: Configure port multiplexing for the socket file descriptor so that reconnection can be performed without port occupation after disconnection from the terminal.

[0082] Specifically, the central control host sets up port reuse for the socket file descriptor to ensure that after disconnecting from the terminal, it can reconnect without port occupation.

[0083] S123: Set the size of the receive and send buffer of the socket file descriptor to reduce memory usage pressure.

[0084] Specifically, the central control host sets the size of the receive and send buffer of the socket file descriptor to reduce the pressure on memory usage. For example, in this embodiment, the size of the buffer can be 1024*1024 bytes.

[0085] S124: Request to establish a connection with the terminal using the socket file descriptor based on the IP address and port number.

[0086] Specifically, the central control host calls the terminal's IP address and port number stored in the memory linked list container, and requests to establish a connection with the terminal using the socket file descriptor based on the IP address and port number.

[0087] S125: When a confirmation connection is received from the terminal, TCP / UDP network communication with the terminal is established.

[0088] Specifically, once the terminal replies with a connection confirmation, the control host can establish TCP / UDP network communication with the terminal.

[0089] S130: Control the terminal according to the control command.

[0090] Specifically, the central control unit can control the terminal to perform corresponding operations after establishing TCP / UDP network communication according to control commands.

[0091] As a further implementation, step S130 may include:

[0092] When a trigger command uploaded by a user via a PC host is received, the terminal is controlled according to the control command; the trigger command includes the single-step command and / or the combined command;

[0093] Alternatively, when the conditions of the time point configuration parameters are met, the terminal is controlled according to the control command;

[0094] Alternatively, when establishing TCP / UDP network communication with the terminal, the terminal can be controlled immediately according to the control command.

[0095] Specifically, users can use the logic editing software on the PC host to trigger the central control host to issue commands (commands refer to single-step commands and combined commands stored in the memory linked list container) to control the terminal.

[0096] Moreover, the control commands in this embodiment do not necessarily need to be manually triggered. The central control host also has a timed trigger function and an immediate trigger function. Timed triggering can be set when configuring the XML file. For example, in the following application scenario: a company holds a group morning meeting at 8:00 am every Monday, so a timed point of 7:50 am can be set. When the timed point is reached, the trigger command is executed to control the equipment in the venue, including but not limited to: turning on the lights, turning on the air conditioner, turning on the sound amplification equipment, turning on the audio-visual equipment, etc.

[0097] After receiving an instruction, the terminal executes the control command and performs terminal control operations. For example, 1: the terminal controls the motor of the curtains, and the terminal's response is to open, close, or stop the curtains; 2: the terminal is a host computer that controls the lights, and the terminal's response is to turn the lights on, off, or flash; 3: the terminal is a camera device, and the terminal's response is to move the camera up, down, left, and right, zoom in, zoom out, or return to the preset point; 4: the terminal is a central air conditioning system, and the terminal's response is to turn the central air conditioning system on and off, switch modes, adjust the temperature, and adjust the fan speed.

[0098] The TCP / UDP-based network communication connection method provided in this application enables the central control host to control one or more terminals with only one network cable connection, without the need for other relay devices.

[0099] This application also provides a TCP / UDP-based network communication connection system, which includes: a PC host, a central control host, and one or more terminals;

[0100] The PC host is connected to the central control host via a network, and the central control host is connected to each of the terminals via a network cable.

[0101] The PC host is used to generate configuration files and / or trigger commands in response to user operations, and upload the configuration files and / or trigger commands to the central control host;

[0102] The central control host is used to execute the above-mentioned TCP / UDP-based network communication connection method;

[0103] The terminal is used to perform corresponding operations in response to the control of the central control host.

[0104] Reference Figure 2This embodiment provides an example structural diagram of a network communication connection system based on TCP / UDP.

[0105] The terminal in this embodiment can include various types of devices, meaning the central control host can simultaneously control different types of terminals. Further, the terminal includes a motor for controlling curtains, a host computer for controlling lights, a camera device, or a central air conditioner;

[0106] When the terminal is the motor controlling the curtain, the terminal is used to respond to the control of the central control host to perform at least one of the curtain opening action, closing action, or stopping action;

[0107] When the terminal is the host computer controlling the light, the terminal is used to respond to the control of the central control host to perform at least one of the following actions: turning the light on, turning it off, or flashing the light.

[0108] When the terminal is the camera device, the terminal is used to respond to the control of the central control host to perform at least one of the following actions: camera up / down / left / right movement, close-up movement, telephoto movement, or return to a preset point.

[0109] When the terminal is the central air conditioner, the terminal is used to respond to the control of the central control host to perform at least one of the following actions: turning the central air conditioner on or off, switching modes, adjusting the temperature, or adjusting the fan speed.

[0110] To facilitate a clearer understanding of this application, a complete optional example will be used to illustrate it below.

[0111] Reference Figure 3 This embodiment provides an example flowchart of a TCP / UDP-based network communication connection method. In this embodiment, the TCP / UDP-based network communication connection method provided in this application can be encapsulated as an embedded software module of the central control host, i.e., a virtual board.

[0112] Specifically, the user edits the terminal's configuration information and control commands on the PC host's logic editing software.

[0113] The configuration information may specifically include the terminal's IP address and port number. The purpose of this configuration information is that when the embedded software module of the TCP / UDP network communication protocol establishes a socket connection with the terminal, it needs to bind the terminal's IP address and port number, and then transmit data to the terminal through this socket file descriptor.

[0114] The specific control commands can perform depend on the type of device the terminal is. Example 1: If the terminal controls a curtain motor, the control commands can control the motor's operation, enabling operations such as opening, closing, and stopping the curtains. Example 2: If the terminal is a host computer controlling lights, the control commands can control the lights to turn on, off, or flash. Example 3: If the terminal is a camera device, the control commands can control the camera's movement (up, down, left, right), zoom in, zoom out, and return to a preset point.

[0115] Then, the XML configuration file is uploaded to the central control host. The embedded software modules of the central control host's TCP / UDP and network communication protocols will parse this XML configuration file. This XML configuration file may include: single-step command module, combined command module, distributed sub-board configuration parameter module, timer configuration module, and keyword matching configuration module.

[0116] Parsing the XML configuration file involves the following steps: Step 1: Open the XML configuration file in read-only mode, read the version number of the newly uploaded XML configuration file, and determine if the version number is higher than that of the old XML configuration file. If so, parse it; otherwise, do not parse it. Step 2: Clear the memory linked list container to prepare for storing data from each module. Step 3: Read the root node of the XML configuration file. The root node is the entry point for reading all data. Step 4: Loop through the child nodes of the root node. Each child node is the entry point for reading parameter module data. Step 5: Loop through the child nodes of the child nodes, which is equivalent to reading single-step commands, combined commands, sub-board configuration parameters, and timer configuration parameters. Step 6: Store the data read in Step 5 into the memory linked list container in categories, ready for use. Step 7: Close the XML configuration file and exit parsing.

[0117] The central control host then quickly establishes TCP / UDP network communication with the terminal based on the IP address and port number provided in the configuration file. The specific steps include: Step 1: Creating a TCP / UDP network socket file descriptor, which is crucial for receiving and sending data. Step 2: Setting port reuse for the socket file descriptor to ensure reconnection without port congestion after disconnection. Step 3: Setting the size of the socket file descriptor's receive and send buffers to reduce memory usage; the buffer size is 1024*1024 bytes. Step 4: Retrieving the terminal's IP address and port number stored in the memory linked list container, and requesting a connection with the terminal using the socket file descriptor. Step 5: The terminal replies with a connection confirmation, thus establishing the communication connection between the TCP / UDP network communication virtual card and the terminal.

[0118] Then, the user triggers the central control unit to issue commands (commands refer to single-step commands and combined commands stored in the memory linked list container) via the logic editing software on the PC host to control the terminal through the TCP / UDP network protocol. It should be noted that this embodiment does not necessarily require manual triggering; the central control unit also has a timer function, which can be set to trigger at a set time when configuring the XML file. Application scenario: A company holds a weekly morning meeting at 8:00 AM every Monday. A timer can be set at 7:50 AM. At the set time, a command is triggered to control equipment in the venue, including but not limited to: turning on lights, air conditioning, public address systems, and audio-visual equipment.

[0119] After receiving an instruction, the terminal executes the control command and performs terminal control operations. For example, 1: the terminal controls the motor of the curtains, and the terminal's response is to open, close, or stop the curtains; 2: the terminal is a host computer that controls the lights, and the terminal's response is to turn the lights on, off, or flash; 3: the terminal is a camera device, and the terminal's response is to move the camera up, down, left, and right, zoom in, zoom out, or return to the preset point; 4: the terminal is a central air conditioning system, and the terminal's response is to turn the central air conditioning system on and off, switch modes, adjust the temperature, and adjust the fan speed.

[0120] With the embedded software module of TCP / UDP network communication protocol, the central control host and the terminal only need to be connected by a single network cable. No other relay equipment is required to enable the central control host to control one or more terminals.

[0121] This application embodiment embeds a virtual board supporting TCP / UDP network communication protocols within the central control host program. The virtual board directly controls terminals that only accept TCP / UDP network communication protocols, thereby eliminating all the negative impacts of adding relay devices. This application embodiment has the following beneficial effects:

[0122] 1. No additional transfer equipment is required; it is purely software-based, further reducing equipment costs.

[0123] 2. Initial setup only requires providing the terminal's IP address and port number to add a TCP / UDP network communication virtual card. The operation is simple and easy to learn.

[0124] 3. If a fault occurs, simply check whether there is an IP address conflict between the terminals or whether the network cable is damaged. The problem can be easily located without the need for technical personnel, making maintenance very convenient.

[0125] Reference Figure 4 This application provides a network communication connection device based on TCP / UDP, including:

[0126] The first unit is used to obtain a configuration file, which includes configuration information of one or more terminals and control commands for the terminals;

[0127] The second unit is used to parse the configuration information in the configuration file to obtain the IP address and port number of the terminal;

[0128] The third unit is used to establish TCP / UDP network communication with the terminal through the IP address and port number;

[0129] The fourth unit is used to control the terminal according to the control command.

[0130] The specific implementation of this network communication connection device is basically the same as the specific embodiment of the network communication connection method described above, and will not be repeated here.

[0134] Memory, as a non-transitory computer-readable storage medium, can be used to store non-transitory software programs and non-transitory computer-executable programs. Furthermore, memory may include high-speed random access memory, and may also include non-transitory memory, such as at least one disk storage device, flash memory device, or other non-transitory solid-state storage device. In some embodiments, memory may optionally include memory remotely located relative to the processor, and these remote memories can be connected to the processor via a network. Examples of such networks include, but are not limited to, the Internet, intranets, local area networks, mobile communication networks, and combinations thereof.

The processor of an electronic device can read the computer instructions from the computer-readable storage medium, and the processor executes the computer instructions, causing the electronic device to perform...

[0136] In some alternative embodiments, the functions / operations mentioned in the block diagrams may not occur in the order shown in the operation diagrams. For example, depending on the functions / operations involved, two consecutively shown blocks may actually be executed substantially simultaneously, or the blocks may sometimes be executed in reverse order. Furthermore, the embodiments presented and described in the flowcharts of this application are provided by way of example to provide a more comprehensive understanding of the technology. The disclosed methods are not limited to the operations and logic flows presented herein. Alternative embodiments are contemplated in which the order of various operations is changed and sub-operations described as part of a larger operation are executed independently.

[0137] Furthermore, although this application is described in the context of functional modules, it should be understood that, unless otherwise stated, one or more of the described functions and / or features may be integrated into a single physical device and / or software module, or one or more functions and / or features may be implemented in a separate physical device or software module. It is also understood that a detailed discussion of the actual implementation of each module is unnecessary for understanding this application. Rather, given the properties, functions, and internal relationships of the various functional modules in the apparatus disclosed herein, the actual implementation of the module will be understood within the scope of conventional technology for an engineer. Therefore, those skilled in the art can implement the application set forth in the claims using ordinary techniques without excessive experimentation. It is also understood that the specific concepts disclosed are merely illustrative and not intended to limit the scope of this application, which is determined by the full scope of the appended claims and their equivalents.

[0138] If the aforementioned functions are implemented as software functional units and sold or used as independent products, they can be stored in a computer-readable storage medium. Based on this understanding, the technical solution of this application, in essence, or the part that contributes to the prior art, or a portion of the technical solution, can be embodied in the form of a software product. This computer software product is stored in a storage medium and includes several instructions to cause an electronic device (which may be a personal computer, server, or network device, etc.) to execute all or part of the steps of the methods described in the various embodiments of this application. The aforementioned storage medium includes various media capable of storing program code, such as USB flash drives, portable hard drives, read-only memory (ROM), random access memory (RAM), magnetic disks, or optical disks.

For the purposes of this specification, "computer-readable medium" can be any means that can contain, store, communicate, propagate, or transmit programs for use by, or in conjunction with, an instruction execution system, apparatus, or device.
