[0066] It should be understood that the specific embodiments described herein are only used to explain the present invention, and are not used to limit the present invention.

[0067] like Figure 1-3 As shown, the present application provides a method for controlling multiple devices through a set of serial port connections, including:

[0068] S1. A control device obtains initial serial port transmission information and sends the initial serial port transmission information to a first controlled device, wherein the control device and the first controlled device are connected in series via a serial port, and the initial serial port transmission information includes a serial port baud rate, a serial port data bit, and a serial port stop bit;

[0069] S2, the first controlled device determines whether to enable the half-duplex connection mode according to the initial serial port transmission information;

[0070] If the half-duplex connection mode is enabled, the first controlled device obtains a plurality of channel occupancy data and a plurality of first transmission data connected to the serial port of the control device, and optimizes the plurality of channel occupancy data and the plurality of first transmission data to obtain a plurality of optimized data;

[0071] S3, the first controlled device sends the plurality of optimization data to a controlled device cluster connected in series therewith, wherein the controlled device cluster includes a plurality of second controlled devices connected in sequence, and any second controlled device in the controlled device cluster is connected in series with the first controlled device as a first target controlled device and receives the plurality of optimization data;

[0072] S4. The target controlled device transmits the multiple optimization data to each second controlled device in the controlled device cluster in a relay manner according to the connection order of the controlled device cluster, until the last second controlled device receives the optimization data and the connection transmission is completed, wherein, after each second controlled device receives the optimization data, each second controlled device obtains the corresponding first startup instruction according to the optimization data, and establishes a controlled connection for each second controlled device according to the multiple first startup instructions.

[0073] As described in the above steps S1-S4, when the master control device is connected through communication transmission, a master control device needs to use a serial port to control multiple devices, wherein the master control device needs to have multiple serial ports, and each controlled device needs a serial port connection of the master control device. The master control device end will be connected to more cables, which will make the master control device more complex. At the same time, the number of devices that the master control device can control will be limited by the number of serial ports on the master control end. When the master control device end is connected to more cables, the connection load of the master control device will increase, which will cause damage to the master control device. Based on this, it is necessary to transmit information at the starting serial port. The serial port baud rate, serial port data bit and serial port stop bit are extracted, and the connection mode between the first controlled device and the controlled device cluster is determined by the serial port baud rate, serial port data bit and serial port stop bit. In this way, the optimal controlled connection can be provided for the main control device through the selection of the connection mode, so that the main control device can run efficiently. When the half-duplex connection mode is turned on, the first controlled device obtains multiple channel occupancy data and multiple first transmission data connected to the serial port of the control device, and optimizes the multiple channel occupancy data and the multiple first transmission data to obtain multiple optimized data. In this way, the channel occupancy data is optimized in advance. The row elimination can provide a real data transmission volume for the transmission of multiple optimized data. At the same time, after the multiple optimized data are sent to the controlled device cluster connected in series, wherein the controlled device cluster includes multiple second controlled devices connected in sequence, any second controlled device in the controlled device cluster is connected in series with the first controlled device as the first target controlled device and receives multiple optimized data, and then the target controlled device transmits the multiple optimized data to each second controlled device in the controlled device cluster in a relay manner according to the connection sequence of the controlled device cluster, until the last second controlled device receives the optimized data and the connection transmission ends, wherein each second controlled device receives the optimized data, and each second controlled device obtains the corresponding first startup instruction according to the optimized data, and establishes a controlled connection for each second controlled device according to the multiple first startup instructions, so that each second controlled device is controlled by the first transmission data transmitted by the previous second controlled device under the relay transmission control, and then the connection control of the master control device is evenly distributed to each second controlled device, thereby effectively reducing the connection load of the master control device and reducing the damage to the master control device.

[0074] In one embodiment, after step S2 of the first controlled device determining whether to enable the half-duplex connection mode according to the initial serial port transmission information, the method further includes:

[0075] S21, if the half-duplex connection mode is not enabled, the first controlled device determines whether to enable the single-channel connection mode according to the initial serial port transmission information;

[0076] S22: If the single-channel connection mode is enabled, the first controlled device obtains the target configuration address;

[0077] S23, the first controlled device obtains address information of multiple third controlled devices in the second controlled device cluster connected in series with it, and traverses all third controlled devices according to the target configuration address, so that the target configuration address successfully matches the address information of any third controlled device in the second controlled device;

[0078] S24, any third controlled device corresponding to a successful match establishes a communication connection with the first controlled device through the target configuration address;

[0079] S25. The control device sends a control instruction to any third controlled device corresponding to a successful match through the first controlled device to establish a controlled connection.

[0080] As described in the above steps S21-S25, when the connection mode is a single-channel connection mode, the first controlled device obtains the target configuration address, the first controlled device obtains the address information of multiple third controlled devices in the second controlled device cluster connected in series with it, and traverses all third controlled devices according to the target configuration address, so that the target configuration address is successfully matched with the address information of any third controlled device in the second controlled device, and any third controlled device corresponding to the successful match is established with the first controlled device through the target configuration address. The control device then sends a control instruction to any third controlled device corresponding to the successful match through the first controlled device to establish a controlled connection, so that the first target controlled device can be directionally controlled in the single-channel connection mode, and in the single-channel connection mode, the first controlled device and the multiple third controlled devices are all used as media for transmission, and only one third controlled device is controlled at a time, which will reduce the connection load of the master control device, and can also control multiple devices in a direction, and can also avoid damage to the master control device due to increased connection load.

[0081] In one embodiment, step S2 of the first controlled device determining whether to enable the half-duplex connection mode according to the initial serial port transmission information includes:

[0082] S201, the first controlled device obtains the corresponding data bit number according to the serial port data bit;

[0083] The first controlled device obtains a constant communication output of the serial port according to the serial port data bit and the serial port baud rate;

[0084] S202, the first controlled device obtains the interval time of the serial port stop bit according to the serial port stop bit;

[0085] S203, the first controlled device obtains a total communication transmission amount according to the constant communication output amount and the interval time of the serial port, and determines whether the total communication transmission amount is less than a preset communication transmission amount;

[0086] If the total communication transmission volume is less than the preset communication transmission volume, the first controlled device starts the half-duplex connection mode.

[0087] As described in the above steps S201-S203, when distinguishing between the half-duplex connection mode and the single-channel connection mode, first obtain the corresponding data bit number according to the serial port data bit, wherein the single-channel data bit number is usually less than 8 digits, and the number of digits above 8 as long as it is an even multiple is usually the number of digits of the half-duplex connection mode. When the data is transmitted, it can be efficiently transmitted in different modes by classification, and then the rated first transmission data can obtain the serial port constant communication output under the conditions of the serial port data bit and the serial port baud rate. In this way, the transmitted data can be preliminarily divided according to the serial port constant communication output, and then the serial port stop bit interval is obtained according to the serial port stop bit, and then according to The total communication transmission volume is obtained by the constant communication output of the serial port and the interval time, wherein the total communication transmission volume is calculated by multiplying the constant communication output of the serial port and the interval time. Since the transmission volume of the single-channel connection mode is faster than the half-duplex connection mode, if the total communication transmission volume transmitted within the preset time is greater than the preset communication transmission volume, it is a single-channel connection mode. On this basis, it is determined whether the total communication transmission volume is less than the preset communication transmission volume. If the total communication transmission volume is less than the preset communication transmission volume, the first controlled device starts the half-duplex connection mode, otherwise, the single-channel connection mode is started. Determining the connection mode is conducive to classifying the instruction data during the connection and can reduce the abnormal resource allocation of the serial port during transmission.

[0088] In one embodiment, the step S2 of the first controlled device acquiring a plurality of channel occupancy data and a plurality of first transmission data connected to the serial port of the control device further includes:

[0089] S204, the first controlled device acquires a corresponding plurality of transmission times according to the plurality of first transmission data, and divides each transmission time into a plurality of time slots according to a preset fixed length;

[0090] S205, the first controlled device sorts a number of time slots to obtain a time slot sorting table;

[0091] S206, the first controlled device classifies the time slot sorting table according to the odd and even numbers in the sorting to obtain a plurality of odd time slots and a plurality of even time slots;

[0092] S207: The first controlled device obtains a first transmission channel corresponding to the half-duplex connection mode, and divides the first transmission channel into a plurality of odd time slots and a plurality of even time slots to obtain a plurality of odd channels and a plurality of even channels;

[0093] S208, the first controlled device obtains a total number of channels according to the plurality of odd-numbered channels and the plurality of even-numbered channels;

[0094] S209, the first controlled device obtains total channel occupancy data according to the first transmission channel;

[0095] S2010: The first controlled device divides the total channel occupancy data according to the total number of channels to obtain a plurality of first channel occupancy data.

[0096] As described in the above steps S204-S2010, the first controlled device of the present invention obtains corresponding multiple transmission times according to multiple first transmission data, and divides each transmission time into multiple time slots according to a preset fixed length, and then the first controlled device sorts the multiple time slots to obtain a time slot sorting table, wherein the time slot is mainly used in the time division multiplexing mode, and then the first controlled device classifies the time slot sorting table according to the odd and even in the sorting to obtain multiple odd time slots and multiple even time slots, so that the channels under the half-duplex connection mode are split in advance, and the data are preliminarily classified, and after the preliminary classification, the confusion caused by multiple data connections can be reduced, and the split data can be sorted according to the odd and even. The even channels are transmitted alternately, and then the first controlled device obtains the total number of channels according to the multiple odd channels and the multiple even channels, wherein each channel is rated to occupy fixed data, wherein the fixed data includes the transmission protocol of the channel and the data occupied by the channel medium, etc. On this basis, the total channel occupancy data can be obtained according to the first transmission channel by the first controlled device, and the first controlled device divides the total channel occupancy data according to the total number of channels to obtain multiple first channel occupancy data, and after the multiple first channel occupancy data are obtained, eliminating them can make the basis for calculating the amount of data for connection transmission correct, so as to facilitate more accurate calculation of the data for connection transmission between the control device and the controlled device.

[0097] In one embodiment, the step S2 of optimizing the plurality of channel occupancy data and the plurality of the first transmission data to obtain a plurality of optimized data includes:

[0098] S4011. The first controlled device obtains a corresponding maximum load transmission rate and a transmission delay rate according to a plurality of first transmission data;

[0099] S4012: The first controlled device obtains a corresponding plurality of transmission bit numbers according to a plurality of the first transmission data;

[0100] S4013: The first controlled device obtains a corresponding plurality of occupied bit numbers according to a plurality of first channel occupation data;

[0101] S4014, the first controlled device sequentially inputs the plurality of transmission bit numbers, the plurality of occupied bit numbers, the maximum load transmission rate and the transmission delay rate into the communication resource optimization model for training, and obtains a plurality of first optimized bit numbers, wherein the function formula of the communication resource optimization model is:

[0102]

[0103] Where b(i…n) represents the first optimized bit number from the i-th to the n-th, STD i Indicates the first transmission data of the i-th time, FZ MAXi represents the i-th maximum load transmission rate, s i represents the i-th transmission delay rate, ZY i Indicates the occupancy data of the first channel of the i-th channel, STD n Indicates the nth first transmission data, FZ MAXn represents the nth maximum load transmission rate, s n represents the nth transmission delay rate, ZY n represents the nth first channel occupation data, wherein i represents the number of first transmission data and first channel occupation data, i=1, 2, 3...n;

[0104] S4015. The first controlled device uses the first optimized bit numbers from the i-th to the n-th as a plurality of optimized data.

[0105] As described in the above steps S4011-S4015, the first controlled device of the present invention obtains the corresponding maximum load transmission rate and transmission delay rate according to multiple first transmission data, and then inputs the multiple first transmission data, multiple first channel occupancy data, maximum load transmission rate and transmission delay rate into the communication resource optimization model for training in sequence to obtain multiple first optimization data. In this way, after the data is optimized, the multiple first optimization data can remain stable during the transmission connection, and the stable transmission connection can avoid confusion in the connection transmission between the control device and the controlled device.

[0106] In one embodiment, the step S23 of traversing all third controlled devices according to the target configuration address further includes:

[0107] S231, the first controlled device obtains the number of occupied data bits of the second channel in the single-channel connection mode;

[0110] S234. The first controlled device calculates the rated transmission rate according to the second channel occupancy data, the number of bits of the configuration address number and the preset transmission time, wherein the calculation formula is:

[0111]

[0112] P represents the rated transmission rate, D(e) represents the number of data bits occupied by the second channel, z(y) represents the number of bits of the configuration address number; T represents the preset transmission time;

[0113] S235: The first controlled device transmits the configuration address number information to all third controlled devices according to the rated transmission rate based on the preset transmission protocol.

[0114] As described in the above steps S231-S235, the first controlled device of the present application obtains the number of occupied data bits of the second channel in the single-channel connection mode, and then the first controlled device obtains the number of configuration address number bits of the configuration address number information, and then the first controlled device obtains the preset transmission time of the configuration address number information in the single-channel connection mode, and then the first controlled device calculates the rated transmission rate according to the second channel occupancy data, the number of configuration address number bits and the preset transmission time. In this way, after obtaining the rated transmission rate, it is beneficial for the first controlled device to traverse the configuration address number information according to the rated transmission rate based on the preset transmission protocol to all third controlled devices, thereby avoiding resource allocation abnormalities when the serial port provides connection transmission between the control device and the controlled device.
