[0028] The technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0029] Figure 1 is the logical structure diagram of the first embodiment of the sensing and monitoring system of the present utility model. The sensing and monitoring system of this embodiment includes a split main body device 10 and a probe device 20. It should be noted here that the main body device 10 can be connected to probe devices 20 of various different communication types.

[0030] Such as Figure 1As shown, in this embodiment, the main device 10 includes a control module 11, a first connector 12, and a wireless communication module 13 that are respectively connected to the control module 11. The control module 11 includes an MCU, and the MCU has multiple IO ports. It should be understood that the number thereof is much larger than M. For example, when the selected MCU model is HC32L136K8TA, the MCU has 40 IO ports. The first connector 12 is used to connect to a probe device of any communication type among multiple probe devices with different communication types, and includes N communication terminals. The N communication terminals of the first connector 12 are connected to the N IO ports of the MCU in a one-to-one correspondence, where N is greater than or equal to the maximum value of the number of communication pins of the multiple probe devices with different communication types. For example, assume that the first connector 12 can connect probe devices of two communication types, and the number of communication pins of the probe device of the first communication type is 2, and the number of communication pins of the probe device of the second communication type is 4. Then, the maximum value of the number of communication pins of these two probe devices with different communication types is 4. At this time, N can be 4, 5, 6, and so on. The wireless communication module 13 is used to send the detection information of the probe device 20 connected by the first connector 12 to the cloud platform under the control of the control module 11.

[0031] As Figure 1 shown, in this embodiment, the probe device 20 includes a probe module 21 and a second connector 22. Among them, the second connector 22 is used to connect to the main device 10 and includes N communication terminals. It should be understood that the second connector 22 is a connector that matches the first connector 12. The communication type of the probe module 21 can be any one of multiple communication types, and the probe module 21 has M communication pins. The M communication pins of the probe module 21 are connected to M communication terminals among the N communication terminals of the second connector 22 in a one-to-one correspondence, where M is less than or equal to N.

[0032] In the sensing and monitoring system of this embodiment, since the main device 10 and the probe device 20 are of a split design, and the first connector 12 of the main device 10 can connect to probe devices 20 of multiple different communication types, that is, one main device 10 can match probe devices of different communication types. Therefore, for manufacturers, the production cost, management cost, and warehousing cost are greatly reduced. Moreover, in actual applications, users can replace the probe device according to actual needs, which also greatly saves costs and has extremely strong promotion and practical value.

[0033] Further, in a specific embodiment, the communication types of the probe device 20 that the main body device 10 can be connected to include, for example, I2C, UART, and SPI. Moreover, N is 4. Specifically, when the communication type of the probe module 21 of the probe device 20 is I2C, it has the following two communication pins: SDA pin and SCL pin. That is, in this probe module 21, M is 2, and the SDA pin and SCL pin of the probe module 21 are respectively and correspondingly connected to two of the four communication terminals of the second connector 22, and the other two communication terminals of the second connector 22 are left floating; when the communication type of the probe module 21 is UART, it has the following two communication pins: TXD pin and RXD pin. That is, in this probe module 21, M is 2, and the TXD pin and RXD pin of the probe module 21 are respectively and correspondingly connected to two of the four communication terminals of the second connector 22, and the other two communication terminals of the second connector 22 are left floating; when the communication type of the probe module 21 is SPI, it has the following four communication pins: SCLK pin, NSS pin, MISO pin, and MOSI pin. That is, in this probe module 21, M is 4, and the SCLK pin, NSS pin, MISO pin, and MOSI pin of the probe module 21 are respectively and correspondingly connected to two of the four communication terminals of the second connector 22. After a probe device 20 is connected to the main body device 10, the second connector 22 of the probe device 20 is connected to the first connector 12. Therefore, the probe module 21 of the probe device 20 transmits the detected information to the control module 11 of the main body device 10 through its corresponding communication pins, the corresponding communication terminals of the second connector 22, and the corresponding communication terminals of the first connector 12.

[0034] In a specific embodiment, as Figure 2 shown, pins 2, 3, 5, and 6 of the first connector J3 are four communication terminals. Specifically, pin 2 is the SDA communication terminal when connecting a probe device of I2C communication type, and is also the MISO communication terminal when connecting a probe device of SPI communication type; pin 3 is the SCL terminal when connecting a probe device of I2C communication type, and is also the MOSI communication terminal when connecting a probe device of SPI communication type; pin 5 is the RXD communication terminal when connecting a probe device of UART communication type, and is also the SCLK communication terminal when connecting a probe device of SPI communication type; pin 6 is the TXD communication terminal when connecting a probe device of UART communication type, and is also the NSS communication terminal when connecting a probe device of SPI communication type. Moreover, as Figure 2As shown, current-limiting resistors R17, R15, R14, and R11 are also connected between each communication terminal of the first connector and the corresponding IO port of the MCU. At the same time, bidirectional voltage-regulating diodes DD1, DD5, DD4, and DD3 are connected between each communication terminal and the ground. It should be understood that the connection method of the second connector to each communication terminal of the first connector is similar. Current-limiting resistors are also connected between each communication terminal of the second connector and the corresponding communication pin of the probe module, and bidirectional voltage-regulating diodes are connected between each communication terminal of the second connector and the ground.

[0035] Of course, in another embodiment, N can also be the sum of the number of communication pins of probe devices of multiple different communication types. For example, when multiple different communication types include I2C, UART, and SPI, the number M of communication pins of the probe modules of the three communication types are 2, 2, and 4 respectively. At this time, N can be 8. In some other embodiments, N can also be 5, 6, 7, etc.

[0036] Furthermore, in some specific embodiments, the first connector 12 can be a first row of pin connectors, and the second connector 22 is a second row of pin connectors. For example, the first connector 12 is a female row of pins, and the second connector 22 is a male row of pins. In some other embodiments, the first connector 12 can be a first aviation connector, and the second connector 22 is a second aviation connector. For example, the first connector 12 is a female aviation connector, and the second connector 22 is a male aviation connector.

[0037] Furthermore, in some embodiments, the wireless communication module 13 is a LoRa module, a ZigBee module, a Bluetooth module, a WIFI module, or a 433M wireless module.

[0038] Furthermore, in some embodiments, the number of the first connectors 12 can be greater than 1, that is, the main device 10 can simultaneously access multiple probe devices 20.

[0039] Furthermore, in some embodiments, the main device 10 further includes a power supply module, which is used to supply power to the control module 11, the wireless communication module 13, and the probe device 20. Moreover, when supplying power to the probe device 20, the first connector 12 further includes a power supply terminal and a grounding terminal. Among them, the power supply terminal of the first connector 12 is connected to the positive output terminal of the power supply module, and the grounding terminal of the first connector 12 is connected to the grounding terminal of the power supply module. For example, as Figure 2 shown, pin 1 of the first connector J3 is the power supply terminal, which is used to connect to the positive output terminal (VA+) of the power supply module, and pin 4 of the first connector J3 is the grounding terminal (GND). In this way, the power supply voltage output by the power supply module can supply power to the accessed probe device 20 through the first connector 12.

[0040] Finally, it should be noted that when the first connector 12 of the main device 10 is connected to probe devices of different communication types, the types of communication pins accessed by the N communication terminals of the first connector 12 may be different. The MCU can determine the communication type of the currently connected probe device 20 by polling multiple known communication protocols. For example, the connected probe device 20 is scanned using the I2C, SPI, and UART communication protocols respectively. If a response message from the probe device 20 is received, the communication type of the probe device 20 can be determined according to the currently used communication protocol. After determining the communication type of the connected probe device 20, the MCU can further perform addressing according to multiple known different address codes. If the address does not match, no response message from the probe device 20 will be received. Then, by continuously changing the address code until a response message is received, at this time, the MCU can read the sensing data of the probe module 21 through the first connector 12 and the second connector 22.

[0041] Furthermore, the MCU can be awakened periodically to periodically determine whether a probe device is connected, and determine its communication type and address code when it is connected. If it is determined that no probe device is connected, it can continue to remain in the sleep state until the next wake-up period arrives.

[0042] In addition, for a probe device with a UART communication type, in addition to passive waiting for MCU polling, it can also actively transmit data through the corresponding communication pins in the second connector 22 and the first connector 12 when it is connected to the main device. When the MCU determines that a complete format of the sensing data packet is received and the verification passes, the type and address code of the probe device can be confirmed through the data parameters. For example, when a probe device with a UART communication type is connected to the main device, if the MCU of the main device determines that a specific IO port (connected to the TXD pin of the probe module with a UART communication type through the corresponding communication terminal of the first connector and the corresponding communication terminal of the second connector) changes from 1 to 0 (pulled down input), it can quickly determine that a probe device with a UART type is connected.
