in this embodiment, both the pin 4 and the pin 5 of the MCU are grounded through the MOS tube in the MCU, as shown in fig. 3, and the switch of the MOS tube is controlled to control the access of the signal input end or the input of the ground end.
In this embodiment, the connection manner between the main line and the auxiliary line of the MCU and other data processing devices includes wired connection and/or wireless connection, and the main application scenario is data transmission of the wireless internet of things, so that the main receiving manner is a wireless connection manner, and the transmission and the reception on the main line and the auxiliary line are mutually independent.
The embodiment also provides a serial data transmission device, which is composed of the plurality of data processing devices, as shown in fig. 2, wherein a data transmission line of the MCU between the data processing devices includes a main line and an auxiliary line, wherein:
the main lines of adjacent MCUs are directly connected in series, and the auxiliary lines of adjacent MCUs are directly connected in series, wherein the connection mode is a wired or wireless mode, and the embodiment is mainly used for data transmission of the wireless internet of things, as another application of the inventor, namely, an NB-IoT device communication system and method, provides an application scene, adjacent NB-IoT devices cannot establish connection with a base station to perform data transmission due to insufficient coverage of base station signals, adjacent NB-IoT devices sequentially establish connection to perform data processing and transmission, and further data of all NB-IoT devices are transmitted to the NB-IoT devices capable of establishing connection with the base station, and all data are sent to the base station through the device. In the above-described process, the serial data transmission device of the present embodiment is utilized.
In fig. 2, when the MCUB is in a normal working state, the MCUB of the intermediate data processing device is exemplified, data information from the MCUA exists on both the main line and the auxiliary line, that is, the pin 2 and the pin 3 can both receive the data information from the previous MCUA, the MCUB selects the data information on the main line for processing, ignores the data information from the pin 3, and sends response information through the pin 1, the L1 line of the auxiliary line is used as a load, the pin 3 is equivalent to short-circuiting the R1, so that the data information transmitted by the previous MCU is cut off at the first resistor R1, and in the process of receiving the data, the pin 4 and the pin 5 for transmitting the data of the MCUB are grounded through MOS tubes, so that the data information transmitted on the auxiliary line is 0, that is, for the previous MCUC, the auxiliary line has no signal transmission.
After the MCUB finishes processing data, the data is sent simultaneously through the main line and the auxiliary line, that is, the pin 5 and the pin 7 send data simultaneously, of course, when the pin 5 sends data, the data needs to be connected to the signal input end through the MOS tube first, and the data sent by the pin 7 is normally sent to the MCUC, on the auxiliary line, because of the unidirectional conductive characteristic of the diode D1, when the pin 5 sends a high level, the output end of the MCUA is not affected, and because the first resistor R1 acts as a load, when the pin 5 sends a low level, the high level and the low level of the output end of the a number are not affected, that is, the data transmitted on the auxiliary line is normally sent to the MCUC, and the MCUC repeats the processing procedure of the MCU.
When the MCUB fails, the main lines on the two sides of the MCUB are disconnected, and all the pins 3, 4, 5 and 6 connected to the auxiliary line float, so that no influence is exerted on the auxiliary line. The main line of the MCUC can not receive the data information of the MCU B, the auxiliary line of the MCUC can not receive the data information of the MCUA, the MCU of the upper stage is judged to be damaged, and then the data information of the MCUA is processed.
In the above, when the signal sent by the MCUA is at a high level, the signal at the high level is still at a high level when being transmitted to the node between the pin 5 and the auxiliary line due to the unidirectional conduction characteristic of the diode between the pin 3 and the pin 5 on the MCUB, and then is further transmitted to the pin 3 of the MCUC; when the signal from MCUA is low, the low level signal cannot pass through the diode, but due to the influence of the ground resistor R11, the level at the junction between the pin 5 of MCUB and the auxiliary line is also low, and the level signal can be transferred to the pin 3 of MCUC. The principle is the same when pin 4 of MCUC performs data return.
Based on the above device, the present embodiment further provides a serial data transmission method, including:
the method comprises the steps that a plurality of data processing devices are connected in series through a protocol, and an MCU in each device is connected with a main line and an auxiliary line;
when the MCU is in a normal working state and data transmission exists on a main line and an auxiliary line connected with the MCU, the MCU selects the data of the main line for processing, ignores the data of the auxiliary line, and cuts off the data of the auxiliary line at the MCU; the MCU transmits the processed data through the main line and the auxiliary line simultaneously;
when the MCU processes the abnormal state, the main line is cut off, data on the auxiliary line is transmitted to the next MCU crossing the MCU, the data is received on the auxiliary line connected with the next MCU, and the data is simultaneously transmitted through the main line and the auxiliary line after being processed.
