Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments.

The embodiment of the present invention provides a UART serial port multiplexing method, device, equipment and medium. The UART serial port multiplexing method can be found in Figure 4 , Figure 4 A schematic diagram of an application scenario of a UART serial port multiplexing method provided in an embodiment of the present invention. The UART serial port multiplexing method is applied to an intelligent communication system 10, wherein the intelligent communication system 10 includes a host device A and at least one slave device (B1, B2, ..., Bn-1, Bn), wherein a first controller of the host device A is connected to a second controller of each slave device (B1, B2, ..., Bn-1, Bn) via the same UART serial port; wherein each of the slave devices is connected in parallel to connect each slave device to the host device A via the same UART serial port.

[0024] Figure 1 The following is a flow chart of a UART serial port multiplexing method provided by an embodiment of the present invention. Figure 1 As shown, the method includes the following steps S110-S120 executed by the first controller.

[0025] S110. If the communication mode is a time-sharing communication mode, the first controller sends first information to each of the slave devices in a cyclic manner according to preset timing communication data to obtain second information fed back by each of the slave devices; wherein the timing communication data includes a communication cycle consisting of multiple time periods.

[0026] In this embodiment, the timing communication data includes a communication cycle consisting of a plurality of time periods, each of which is configured with corresponding device information; for example, the communication cycle includes a first time period, a second time period and a third time period, and the communication cycle can be set to 1 second, the first time period is 0 to 0.3 seconds, and the first time period is configured with device information of slave device B1; the second time period is 0.3 to 0.6 seconds, and the second time period is configured with device information of slave device B2; the third time period is 0.6 to 0.9 seconds, and the third time period is configured with device information of slave device B3; within a communication cycle, the first controller sends first information to the corresponding slave device according to the device information corresponding to the current time period, and the first information can be data acquisition request information, and the first information can be transmitted to the corresponding slave device by the first controller. The slave device sends the first information to obtain the second information fed back by the corresponding slave device, wherein the second information is the information collected by the slave device; for example, the current time period is the first time period, and the first controller will continuously send the first information to all slave devices, however, the first information has the device information of the slave device B1 (which can also be understood as tag information), therefore, the first information sent by the first controller can only be recognized by the slave device B1, and cannot be recognized by other slave devices, therefore, within the first time period, only the slave device B1 will reply to the first information, and the reply content is the second information, which may be the information collected by the slave device B1; when the first time period ends and reaches the second time period, the information exchange will automatically switch, at which time, the first controller communicates with the slave device B2.

[0027] In one embodiment, step S110 includes: the first controller confirms the time period corresponding to the current time based on the cycle start time, cycle end time and time period information in the timing communication data of the current communication cycle; wherein each time period in the communication cycle is configured with corresponding device information; the first controller generates corresponding first information based on the device information corresponding to the current time period and sends it to the corresponding slave device.

[0028] In this embodiment, before the first controller sends the first information, it will confirm the time period corresponding to the current time based on the cycle start time, cycle end time of the current communication cycle and the time period information in the timing communication data; wherein the time period information includes the sequence of each of the time periods and the length of each time period; each time period in the communication cycle is configured with corresponding device information; the first controller generates corresponding first information based on the device information corresponding to the current time period and sends it to the corresponding slave device to obtain the corresponding information collected by the slave device (i.e., the second information).

[0029] In one embodiment, before confirming the time period corresponding to the current time, the method further includes: if the current time reaches the cycle end time, the first controller enters the next communication cycle and uses the cycle end time as the cycle start time of the next communication cycle.

[0030] In this embodiment, if the current time reaches the cycle end time, the first controller enters the next communication cycle and uses the cycle end time as the cycle start time of the next communication cycle, and then confirms the current time period based on the time period information of the next communication cycle, wherein the time period information includes the sequence of each time period and the length of each time period, and the current time period is confirmed based on the sequence of each time period and the length of each time period, and then the current communication object is confirmed.

[0031] S120: If the communication mode is the on-demand communication mode, the first controller obtains third information from the slave device and sends corresponding fourth information to the corresponding slave device.

[0032] In this embodiment, the slave device can be an intelligent device such as an infrared sensor, a temperature and humidity sensor, etc. Assuming that at a certain moment the infrared sensor detects that someone is approaching, it will send a third message to the host device so that it can process the third information and feedback (the specific data processing method is not limited); the first controller obtains the third information from the slave device and sends the corresponding fourth information to the corresponding slave device. The fourth information can be a reply message to inform the corresponding slave device to receive and process the third information; specifically, the first controller can parse the third information. If the data format of the third information meets the preset protocol format requirements, the fourth information is returned to the corresponding slave device to let it know that the third data has been given to the host device.

[0033] The embodiment of the present invention provides two communication modes, namely, a time-sharing communication mode and an on-demand communication mode. Both the time-sharing communication mode and the on-demand communication mode have the advantages of low cost and low power consumption. During the communication development process of the product, a suitable communication mode can be selected according to product requirements and specific usage scenarios. Among them, the time-sharing communication mode communicates with each slave device according to preset timing communication data, and has the advantage of high fault tolerance compared to the on-demand communication mode. The on-demand communication mode communicates with the slave device on demand, and has the advantages of high communication efficiency and fast response speed compared to the time-sharing communication mode.

[0034] The method also includes the following steps performed by the second controller: when the communication mode is an on-demand communication mode, the second controller determines whether the collected real-time data meets the information request conditions; if so, the second controller generates corresponding third information based on the real-time data and sends it to the host device.

[0035] In this embodiment, when the communication mode is an on-demand communication mode, the second controller will determine in real time whether the collected real-time data can be reported to the host device based on the preset information request conditions; for example, when the slave device is a temperature and humidity sensor, the temperature and humidity information of the target area will be detected in real time. If the temperature and humidity information is detected to be greater than the preset change threshold, the current temperature and humidity information will be used as the third information and sent to the host device.

[0036] In one embodiment, after the second controller generates corresponding third information according to the real-time data and sends it to the host device, it also includes: if the fourth information from the host device is not received within a preset response waiting time, the second controller resends the third information to the host device.

[0037] In this embodiment, when multiple slave devices simultaneously send data to the host device through the same UART serial port, data collision may occur, resulting in data upload failure. Therefore, if the fourth information is not received from the host device within the preset response waiting time, the second controller will resend the third information to the host device according to the preset protocol format requirements.

[0038] In one embodiment, before the second controller generates corresponding third information based on the real-time data and sends it to the host device, it also includes: the second controller detects the UART serial port to obtain the transmission status of the UART serial port; if the transmission status is a busy state, it returns to execute the step of detecting the UART serial port after delaying a preset waiting time.

[0039] In this embodiment, in order to avoid or reduce the occurrence of data collision, the second controller will first detect the UART serial port to obtain the transmission status of the UART serial port before sending the third information to the host device; if the transmission status is busy, it will return to the step of detecting the UART serial port after a preset waiting time, and will not send the third information to the host device until the detected transmission status is idle.

[0040] In one embodiment, after the second controller detects the UART serial port to obtain the transmission status of the UART serial port, it also includes: if the transmission status is an idle state, executing the step of the second controller generating corresponding third information according to the real-time data and sending it to the host device.

[0041] In this embodiment, if the transmission state is an idle state, the second controller generates corresponding third information according to the real-time data and sends it to the host device to reduce data collision and improve data upload efficiency and communication efficiency.

[0042] Furthermore, if the transmission states detected within a unit time are all idle states, a step is executed in which the second controller generates corresponding third information according to the real-time data and sends the third information to the host device.

[0043] In summary, the embodiments of the present invention provide two communication modes, namely, a time-sharing communication mode and an on-demand communication mode. Both the time-sharing communication mode and the on-demand communication mode have the advantages of low cost and low power consumption. During the communication development process of the product, a suitable communication mode can be selected according to product requirements and specific usage scenarios. Among them, the time-sharing communication mode communicates with each slave device according to preset timing communication data, and has the advantage of high fault tolerance. The on-demand communication mode communicates with the slave device on demand, and has the advantages of high communication efficiency and fast response speed.
