[0026] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0028] Example 1

[0029] Reference Figure 1-8 , is the first embodiment of the utility model, which provides a modular acquisition controller, including an acquisition module 100, wherein the A1 / B1 pin of the acquisition module 100 is connected to the respective A1 / B1 pins of the control module 200, the relay module 300 and the sensor 400 for communication; a touch screen 500, wherein the A2 / B2 pin of the touch screen 500 is connected to the A2 / B2 pin of the acquisition module 100 for communication. The acquisition module 100 includes a first MCU module 101, and the first MCU module 101 communicates with the EEPROM storage module 102 via an I2C interface;

[0030] The first MCU module 101 performs serial communication with the first RS485 module 103 and the 4G module 104 respectively through the UART interface;

[0031] The first MCU module 101 controls the on and off of the first LED indicator light 105 .

[0032] The acquisition module 100 further includes a first power module 106 , which inputs a 12-24V DC voltage and outputs a 3.3V DC voltage to the first MCU module 101 .

[0033] The control module 200 includes a second MCU module 201, which communicates serially with the second RS485 module 202 via a UART interface; the second MCU module 201 controls the on and off of the relay module 204 and the second LED indicator light 206; the second MCU module 201 is also connected to the optocoupler switch module 203 and the dip switch module 205, the optocoupler switch module 203 is used to manually control the relay module 204, and the dip switch module 205 is used to identify the ID of different control modules 200.

[0034] The control module 200 further includes a second power module 207 , which inputs a 12-24V DC voltage and outputs a 3.3V DC voltage to the second MCU module 201 .

[0035] The relay module 300 includes a LoRa module 301, and the LoRa module 301 performs serial communication with a third RS485 module 302 via a UART interface;

[0036] The LoRa module 301 controls the on and off of the third LED indicator light 303 .

[0037] The relay module 300 further includes a third power module 304 , which inputs a 12-24V DC voltage and outputs a 5V DC voltage to the LoRa module 301 .

[0038] When working, the acquisition module 100 plays a core role as the hub of communication between devices. It sends query instructions to the sensor 400 through the Modbus protocol, collects sensor data, and transmits the data to the touch screen 500 in real time. Once the acquisition module 100 receives a control instruction from the touch screen 500, or when the value of the RS-485 type temperature, humidity, light, CO2 sensor, etc. reaches the preset threshold and triggers the control strategy stored in the collector EEPROM, the acquisition module 100 will respond quickly and issue corresponding instructions to the control module 200.

[0039] After receiving these instructions, the controller will first identify whether the controller ID in the instruction matches its own DIP switch ID. If the identification is successful, it will control the corresponding device according to the instruction content.

[0040] Example 2

[0041] Reference Figure 2 , which is the second embodiment of the utility model, is different from the first embodiment in that: the control module 200, the relay module 300 and the sensor 400 are each provided with n groups, wherein n is a natural number greater than or equal to 1, and the communication of each group of relay modules 300 supports both wired and wireless communications.

[0042] This arrangement is for connecting two different relay modules 300 when long-distance wireless transmission is required, and wireless communication can be achieved by configuring these two modules to the same communication channel.

[0043] Likewise, each relay module 300 communicates with its own control module 200 and sensor 400, and each part can be modularly customized.

[0044] Example 3

[0045] Referring to Table 1, it is the third embodiment of the utility model. It is different from the first two embodiments in that this embodiment provides a scenario in which the above-mentioned modular acquisition controller is applied to greenhouses such as vegetables and fruits. Taking the scenario of smart agricultural greenhouses as an example, the acquisition module 100 is connected to the RS-485 type temperature, humidity, light, and CO2 sensors through the first RS485 communication module 103 integrated on the acquisition board to realize real-time acquisition of greenhouse environmental data. The collected environmental data is stored in the EEPROM storage module 102 after being processed by the first MCU module 101, and is uploaded to the touch screen and the cloud platform in real time through the first RS485 communication module 103 and the 4G module 104 respectively. The control module 200 is connected to the first RS485 communication module 103 of the acquisition module 100 through the second RS485 communication module 202 integrated on the control board, and the relay The device module 204 is connected to the controlled devices such as the film roll and solenoid valve in the greenhouse. The dip switch module 205 is used to identify the ID of the control module 200 so that the acquisition module 100 can identify different control modules 200. The optocoupler switch module 203 is used to manually control the relay module 204. When the change of greenhouse environmental data triggers the control strategy stored in the EEPROM storage module 102, the acquisition module 100 issues corresponding control instructions to the control module 200 through the first RS485 communication module 103. The control module 200 receives the instructions and controls the controlled devices to complete the corresponding instructions through the control of the relay module 204. The relay module 300 connects the first RS485 module 103 or the second RS485 module 202 on the acquisition module 100 through the third RS485 module 302 to realize wireless communication to adapt to special scene requirements.

[0046] As shown in Table 1 below, some data of temperature, humidity, CO2, light and other parameters are collected uninterruptedly around the clock. From the data in the table, it can be seen that the temperature, humidity, CO2 and light data collected by the utility model in one day all show excellent accuracy and stability. And after rigorous experimental verification, the response time between each module of the utility model is less than 0.5 seconds, and the response is fast. At the same time, the wireless communication distance of the repeater can reach up to 2000 meters, ensuring the efficiency and reliability of data transmission.
