[0008] When the signal processing module is disconnected from the signal interface, the signal pattern of the signal interface is stored;

[0009] When the signal processing module is connected to the signal interface, it is determined whether the signal processing module matches the stored signal pattern.

[0010] If so, then a detection signal is received from the signal processing module according to the signal pattern, or a control signal is sent to the signal processing module.

[0040] This invention provides a control device for an experimental apparatus, wherein the structure of the experimental apparatus is as follows: Figure 1 As shown, the system includes multiple experimental modules 11, a detection module 12, an execution module 13, and a control device 14 as described in this embodiment. The experimental device module 11 includes multiple experimental devices, each used to perform different experimental functions. For example, the experimental equipment can be used for process experiments on absorption and desorption equipment.

Each detection element can detect the corresponding experimental device during the experiment to obtain a corresponding detection signal. In this embodiment, the detection elements of the detection module 12 can be temperature sensors, pressure sensors, flow sensors, or level sensors.

[0042] The aforementioned execution module 13 includes multiple execution elements, each of which is connected to a corresponding experimental device to control the corresponding experimental equipment. In this embodiment, the execution elements of the execution module 13 can be electric heaters, frequency converters, pumps, fans, or electrically adjustable valves.

The frequency converter can be installed on the power supply line of the heat exchanger, absorption tower, desorption tower, drying tower, or tank to control the power of the heat exchanger, absorption tower, desorption tower, drying tower, or tank during operation.

[0043] The structure of the control device 14 of the experimental equipment in one embodiment of the present invention is as follows: Figure 2 As shown, the device includes a signal processing module 21 and multiple signal processing modules 22. The signal processing module 21 includes a processor 211 connected to at least one signal interface 212. Each signal interface 212 can be detachably connected to any one of the signal processing modules 22, for example, via a signal line. Each of the aforementioned signal processing modules 22 is used to connect to the detection element in the detection module 12 to acquire the detection signal of the experimental device detected by the detection element during the experiment and send it to the processor 211; or it is used to connect to the execution element in the execution module 13 to send control signals received from the processor 211 to the execution element in the execution module 13 during the experiment, thereby completing the experiment.

[0044] In Adoption Figure 1 When conducting experiments with the experimental equipment shown, firstly, connect the signal output terminals of the detection elements in the detection module 12 and the control signal terminals of the execution elements in the execution module 13 to the corresponding signal processing module 22, and then connect the signal processing module 22 to the signal interface 212 to complete the setup of the experimental equipment. During the experiment, the processor 211 obtains the signal modules of each signal interface 212 according to the signal processing module 22 connected to each signal interface 212, and then obtains detection signals from the corresponding signal processing module 21 or sends control signals to the corresponding signal processing module 22 according to the signal mode of each signal interface 212.

[0045] Taking an experiment on an absorption tower as an example, the actuating components of the absorption tower include a fan and an absorbent pump. The fan is connected to the gas inlet at the bottom of the absorption tower to deliver the absorbent gas into the tower. The absorbent pump's inlet is connected to the absorbent tank, and its outlet is connected to the liquid inlet at the top of the absorption tower to deliver the absorbent liquid from the tank into the tower. The detection components of the absorption tower include an absorbent gas flow sensor, an absorbent liquid flow sensor, a pressure sensor, and a temperature sensor. The absorbent gas flow sensor is installed on the pipe between the fan and the gas inlet at the bottom of the absorption tower to measure the flow rate of the absorbent gas entering the tower. The absorbent liquid flow sensor is installed on the pipe between the absorbent pump and the liquid inlet at the top of the tower to measure the flow rate of the absorbent liquid entering the tower. The pressure sensor and temperature sensor are both installed on the absorption tower to detect the pressure of the absorbent gas and the temperature of the absorbent liquid inside the tower, respectively.

[0046] During the experiment on the absorption tower, the signal output terminals of the pressure sensor, absorbent gas flow sensor, absorbent liquid flow sensor, and temperature sensor were connected to the corresponding signal processing module 22. The control signal terminals of the fan and absorbent liquid pump were also connected to their respective signal processing modules 22. Each signal processing module 22 was then connected to the signal interface 212. During the experiment, the selected absorbent gas flow sensor detected the flow rate of the absorbent gas entering the absorption tower, the selected absorbent liquid flow sensor detected the flow rate of the absorbent liquid entering the absorption tower, the selected temperature sensor detected the temperature of the absorbent liquid inside the absorption tower, and the selected pressure sensor detected the pressure of the absorbent gas inside the absorption tower.

[0047] In this embodiment, the method for controlling the experimental equipment by the processor 211 further includes:

[0048] When a signal processing module 22 is connected to the signal interface 212 for the first time, signal matching is performed on the signal processing module 22 to identify the signal mode corresponding to the signal processing module 22.

[0049] When the connection between the signal processing module 22 and the signal interface 212 is disconnected, the processor 211 stores the signal mode of the signal processing module 22 and uses the signal mode as the preset signal mode of the signal interface 212.

[0050] When a signal processing module 22 is connected to the signal interface 212 again, it is determined whether the stored preset signal mode of the signal interface 212 matches the signal processing module 22.

[0051] If so, then receive a detection signal from the signal module or send a control signal to the signal module according to the preset signal mode;

[0052] If not, signal matching is performed on the signal processing module 22 to identify the signal pattern corresponding to the signal processing module 22.

[0053] In this embodiment, the method of the processor 211 for signal matching of the signal processing module 22 includes: sequentially receiving and transmitting signals to the signal processing module 22 according to various signal modes, so as to obtain the signal mode that matches the connected signal processing module 22, that is, to obtain the signal mode of the signal processing module 22.

[0054] In summary, the control device 14 of this embodiment modularly configures the signal processing module 22 and the signal calculation module 21, and the signal calculation module 21 is provided with a signal interface 212 that can be detachably connected to the signal processing module 22. During experiments, the control device 14 of this embodiment can select the corresponding signal processing module 22 to connect to the signal interface module 212 according to requirements, thereby enabling free expansion and personalized settings of experimental functions to achieve multiple experimental functions and improve the applicability, flexibility, and versatility of the experimental equipment.

[0055] Furthermore, in this embodiment, the processor 211 in the signal processing module 21 has a memory function. When the connection between the signal processing module 22 and the signal interface 212 is disconnected, the signal pattern of the signal processing module 22 is stored in memory. When the signal interface 212 is reconnected to the signal processing module 22, it will first determine whether the signal processing module 22 matches the stored signal pattern. Therefore, during the experiment, the experimenter can connect the same signal processing module 22 to the same signal interface 212 so that the signal interface 212 and the signal processing module 22 can communicate instantly without the need for a signal matching process. This improves the efficiency of the processor 211 in data processing, reduces the operation process of the experimenter, and shortens the experiment time.

[0056] In one embodiment of the present invention, the control device 14 of the present invention is further provided with a signal integration module 23, such as... Figure 3 As shown, the signal integration module 23 includes an integrated signal board with an internal interface 231 and an external interface 232. The external interface 232 can be located at the edge of the signal integration board and is used to connect to the detection element in the detection module 12 or the execution element in the execution module 13. The internal interface 231 can be detachably connected to the signal processing module 22 and includes a data-side interface and a device-side interface. The device-side interface is connected to the external interface 232, and the data-side interface is connected to the signal interface 212 to form a data channel from the external interface 232 to the device-side interface, the signal processing module 22, and the data-side interface.

[0057] When conducting experiments using the control device 14 of this embodiment, such as Figure 4 As shown, the detection and execution elements required in the experiment are first connected to the external interface 232 of the signal integration module 23, and each signal processing module 22 is connected to the corresponding internal interface 231, so that the processor 211 is connected to the corresponding detection or execution element through each signal processing module 22.

[0058] For example, when the signal processing module 22 is a module for processing detection signals, the signal input terminal of the signal processing module 22 is connected to the device-side interface in the internal interface 231, and is connected to the corresponding external interface 232 through the device-side interface, so as to connect the detection element to the signal input terminal of the signal processing module 22; the signal output terminal of the signal processing module 22 is connected to the data-side interface in the internal interface 231, and is connected to the signal interface 212 through the data-side interface, so as to connect the signal output terminal of the signal processing module 22 to the processor 211.

[0059] When the signal processing module 22 is a module for processing control signals, the signal input terminal of the signal processing module 22 is connected to the data side interface in the internal interface 231, and is connected to the corresponding signal interface 212 through the data side interface, so as to connect the signal input terminal of the signal processing module 22 to the processor 211; the signal output terminal of the signal processing module 22 is connected to the device side interface in the internal interface 231, and is connected to the corresponding external interface 222 through the device side interface, so as to connect the signal output terminal of the signal processing module 22 to the corresponding actuator.

[0060] With the configuration of this embodiment, each signal processing module 22 can be connected to the detection element, the execution element and the signal operation module 21 through the signal integration module 23, thereby improving the compactness of the control device 14 structure and making the control device 14 easy to install in experimental equipment.

[0061] In the above embodiments, each signal processing module 22 can be detachably connected to the internal interface 231 on the signal integration module 23 via signal lines. In other embodiments, the two can be detachably connected in other ways. The following describes other detachable connection methods in conjunction with specific application scenarios.

[0062] In one embodiment of the present invention, the signal processing module 22 is detachably connected to the internal interface 231 via a plug-in method.

[0063] like Figure 5As shown, pins can be set in the signal processing module 22, and the internal interface 231 can be set as a slot corresponding to the pins. When using the signal processing module 22, the signal processing module 22 can be plugged into the internal interface 231; when not using or replacing the signal processing module 22, the signal processing module 22 can be unplugged from the internal interface 231.

[0064] The configuration method of this embodiment can improve the reliability of the connection between the signal processing module 22 and the internal interface 231, and reduce the complexity of the signal processing module 22 and the internal interface 231 compared with the signal line connection method.

[0065] In one embodiment of the present invention, each internal interface 231 has the same structure, and each signal processing module 22 is provided with a plug interface of the same structure, so that each signal processing module 22 can be plugged into any one of the internal interfaces 231.

[0066] For example, when the internal interface 231 is a slot, the number, size and distribution of the slots in each internal interface are the same; the connectors on the signal processing module 22 are pins, and the number, size and distribution of the pins on each signal processing module 22 interface are the same, and they all correspond to the internal interface 231.

[0067] The configuration method of this embodiment can improve the versatility of the signal processing module 22 and the internal interface 231, so that the signal processing module 22 can be connected to any internal interface 231, thereby improving the ease of use of the control device 14.

[0068] In one embodiment of the present invention, the signal interface 212 on the signal processing module 21 and the data side interface in the internal interface 231 are detachably connected by plugging.

[0069] For example, the signal interface 212 can be configured as a slot, and the data side interface of the internal interface 221 can be configured as a pin. Through the cooperation of the slot and the pin, the signal integration module 23 can be plugged into the signal processing module 23, and the processor 211 can be connected to the data side interface of the internal interface 231.

[0070] With the configuration of this embodiment, the signal processing module 21 and the signal integration module 23 can be detachably connected. When the signal processing module 21 or the signal integration module 23 malfunctions or needs to be replaced, the connection between the signal processing module 21 and the signal integration module 23 can be disconnected, thereby improving the flexibility of the control device 14.

[0071] In one embodiment of the present invention, when the signal processing module 22 is connected to the internal interface 231, the signal processing module 22, the signal integration module 23 and the signal operation module 21 are distributed sequentially in a set direction.

[0072] For example, the signal processing module 22, the signal integration module 23, and the signal operation module 21 can be arranged vertically, with the signal integration module 23 inserted above the signal operation module 21 and the signal processing module 22 inserted above the signal integration module 23. This reduces the horizontal space occupied by the control device 14 and makes it easier to install and arrange the control device 14 within the internal space of the experimental equipment.

[0073] In one embodiment of the present invention, each internal interface 231 is connected to a plurality of external ports 232 via a device-side interface, thereby enabling each internal interface 231 to input multiple signal sources to the signal processing module 22, and each signal processing module 22 can connect to a plurality of detection elements or execution elements of the same type via the corresponding device-side interface.

[0074] For example, when the signal input module 22 connected to the internal interface 231 is used to connect temperature sensors, the signal output terminals of multiple temperature sensors can be connected to the corresponding external interfaces 232 respectively, so as to connect multiple temperature sensors to the signal processing module 22. After each temperature sensor detects a temperature signal, the signal processing module 22 can process each temperature signal and send it to the processor 211. Alternatively, when the signal processing module 22 connected to the internal interface 231 is used to connect actuators such as heat exchangers, the control signal terminals of multiple heat exchangers can be connected to the corresponding external interfaces 232. After the signal processing module 22 obtains the control signal of the heat exchanger output by the processor 211, it transmits the control signal to the control signal terminal of each heat exchanger through the corresponding external interface 232 to control each heat exchanger.

[0075] By using the configuration method of this embodiment, multiple signal sources can be input into the signal processing module 22, thereby reducing the number of internal interfaces 231, reducing the size of the signal integration module 23, and facilitating the installation of the control device 14.

[0076] In one embodiment of the present invention, each external interface 232 is provided with a corresponding crimp terminal, and each crimp terminal is used for detachably connecting a detection element or an actuation element.

[0077] The configuration method of this embodiment can improve the convenience of connecting the signal processing module 22 with the detection element and the execution element, and reduce the difficulty of using the experimental equipment.

[0078] In one embodiment of the present invention, the plurality of signal processing modules include a PT signal processing module, an AD signal processing module, a DA signal processing module, and a DO signal processing module. The PT signal processing module is connected to the signal output terminal of a temperature sensor to process the temperature signal, for example, by performing method processing or filtering. The AD signal processing module is connected to the signal output terminal of a pressure sensor, a flow sensor, or a level sensor to convert the pressure signal, flow signal, or level signal from an analog signal to a digital signal. The DA signal processing module is connected to the control signal terminal of an electric heater or an electrically adjustable valve to convert the control signal from the processor 211 to the electric heater or electrically adjustable valve from a digital signal to an analog signal. The DO signal processing module is connected to the control signal terminal of a pump, a fan, or a solenoid valve to convert the control signal from the processor 211 to the pump, fan, or solenoid valve into a corresponding level signal.

[0079] In one embodiment of the present invention, the signal processing module 21 further includes a communication unit 213 connected to the processor 211, such as... Figure 6 As shown, the communication unit 213 is used for communication connection to the human-computer interaction device.

[0080] The processor 211 is connected to the communication unit 213. The communication unit 213 can be a wired communication unit or a wireless communication unit. When the communication unit 213 is a wired communication unit, it can use a USB interface, a data communication serial port, etc. When the communication unit 213 is a wireless communication unit, it can use Bluetooth, WIFI, or other wireless communication units.

[0081] The aforementioned communication unit 213 is used to establish a communication connection between the human-computer interaction device and the processor 211 by communicating with mobile phones, tablets, computers, and other human-computer interaction devices. After receiving the experimental signal from the signal processing module 22, the processor 211 can send the experimental signal to the human-computer interaction device through the communication unit 213, and the processor 211 can also receive information sent by the human-computer interaction device from the communication unit 312.

[0082] The configuration method of this embodiment allows the human-computer interaction device to be connected to the processor 211, enabling the processor 211 to send the detection signals acquired during the experiment to the human-computer interaction device for analysis of the experimental data; and enabling the human-computer interaction device to send control commands to the processor 211 to control the experimental process.

[0083] Therefore, those skilled in the art should recognize that although numerous exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications conforming to the principles of the present invention can be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the invention. Thus, the scope of the present invention should be understood and construed as covering all such other variations or modifications.
