Referring to FIG. 1 , an embodiment of the present invention provides an intelligent control system for signal acquisition of solution microparticles, including:

The server is used to control the start and stop of the sampling process of the signal intelligent acquisition equipment, and to process and analyze the received acquisition data;

A signal intelligent acquisition device includes a logic control device and an acquisition device, the logic control device is used for intelligently controlling the state of the valve switch in the acquisition device to realize the control of the acquisition process, and for data communication with the server.

Among them, the acquisition device includes a dual-control peristaltic pump, a solution chamber to be tested, a liquid storage chamber, a valve, and a sensor, wherein forward rotation and reverse rotation can be performed, and a solution pipeline to be tested is arranged between the solution chamber to be tested and the storage chamber. The channel and the valve A of the solution pipeline to be tested are provided with sensors inside the liquid storage chamber to collect the ambient air pressure and liquid level height inside the liquid storage chamber, and the upper and lower valves B and C are provided up and down the liquid storage chamber;

When sampling the solution particle signal, the user only needs to put the solution to be tested into the solution chamber to be tested, and the logic control device starts the sampling process after receiving the sampling start instruction sent by the server and the sampling parameter configuration such as the sampling rate. The pipeline valve of the solution to be tested is opened, and the upper and lower valves of the liquid storage chamber are closed at the same time, and the peristaltic pump starts to sample and collect signals according to the set rate. When the liquid level of the liquid storage chamber reaches the extreme value, the peristaltic pump and the valve of the solution pipeline are automatically closed, and the upper and lower valves of the liquid storage chamber are opened to start the liquid discharge, waiting for the next detection. When the hole is blocked during the sampling process, the device will automatically reverse the peristaltic pump to blow out the blocked particles. When the fault cannot be eliminated, the device will activate the sound and light alarm function and prompt the cause of the fault in the background. During the solution sampling process, the data is sent to the background in real time and the signal waveform is displayed graphically. After the sampling is over, the background will automatically generate a data report according to the requirements.

property type	property flag	category
Device Information	0x01	GET
Local network information	0x02	GET
Peer network information	0x03	GET
System log information	0x04	GET
network time synchronization	0x05	SET
ADC sampling clock	0x06	GET/SET
Sound and light alarm	0x07	SET

Baseline adjustment	0x08	SET

Table 3 Attribute types of operational attributes

After receiving the operation control instruction and the sampling start/stop control instruction of the server through the first communication channel, the intelligent signal acquisition device makes a matching judgment based on the parsed message data:

Determine whether the message format matches the preset format. If it does not match, it means that the instruction is in an invalid format, and the device does not send a response message to the server. If it matches, the next matching judgment is performed;

Determine whether the operation command in the message matches. If it does not match, that is, the command has an invalid attribute and is not the type of operation attribute preset by the system, then the device sends an operation command execution failure message to the server, that is, the value of the operation result field in the data frame is modified. It is 0x86 and sent to the server. If it matches, the device executes the operation command and sends the operation command execution success message to the server, that is, the operation result field value in the data frame is modified to 0x80 and sent to the server.

When receiving the sampling start and stop control instruction of the server, the steps of the signal acquisition control method include:

The signal intelligent acquisition device receives the ADC sampling clock setting message sent by the server from the first communication channel;

During the sampling process of the signal intelligent acquisition device, the server sends the sampled data through the second communication channel. The second communication channel is mainly used for the transmission of the sampled data, and the data frame size of each transmission is fixed. The platform obtains data by identifying the start and terminator of the data frame. The format of the data message is shown in Table 4.
