the data receiving unit 231 is used for receiving the pneumatic data sent by the field data sending device;
the data recording unit 232 is connected with the data receiving unit 231 and is used for recording the pneumatic data received by the data receiving unit and filing and classifying the recorded pneumatic data;
the online detection unit 233 is connected to the data recording unit 232, and is configured to perform real-time online detection on the pneumatic data recorded by the data recording unit 232, and output a detection result for a user to check.
Specifically, in this embodiment, the field data acquisition device 21 is used to collect the pneumatic data generated in each process equipment and electrical instrument equipment in the pneumatic transmission system on the field. The pneumatic data generated by the process equipment and the electrical equipment, such as the compressor and the roots blower described above, can be used to indicate the current operating conditions of the compressor and the roots blower, respectively. Therefore, the process equipment and the electrical equipment may be different in different pneumatic conveying systems, and the pneumatic data generated thereby is also different, which is not described in detail herein.
In this embodiment, the field data collecting device 21 collects the pneumatic data and then transmits the pneumatic data to the field data transmitting device 22, and the field data transmitting device 22 transmits the pneumatic data to a remotely connected data server 23 in a wireless manner.
In this embodiment, the data receiving unit 231 in the data server 23 is responsible for receiving the pneumatic data transmitted wirelessly, and records the pneumatic data through the data recording unit 232 and performs the classification. The filing classification means to classify the recorded pneumatic data according to the types of the corresponding process equipment and electrical equipment, and to file and store the classified pneumatic data, so as to facilitate the subsequent data detection processing.
In this embodiment, the online detection unit 233 in the data server 23 acquires the archived and classified pneumatic data from the data recording unit 232, and performs detection processing on each pneumatic data, so as to determine whether abnormal data occurs in the pneumatic data, and output a detection result, so that a user can check and optimize the operation of the user, thereby improving the stable operation of the system.
In the preferred embodiment of the present invention, the field data acquisition device 21 is implemented by an on-site control system. The local control system may be a Programmable Logic Controller (PLC) control system, which may further include a plurality of computer devices and server devices, so as to form a complete local control system (as shown in fig. 4).
In a preferred embodiment of the present invention, a wireless router (not shown) may be disposed in the field data transmitting device 22, and the field data transmitting device 22 transmits the pneumatic data to the data server through the wireless router.

Therefore, the online detection unit 233 compares any one of the pneumatic data recorded in the data recording unit 232 with the corresponding standard pneumatic data:
if the pneumatic data is matched with (i.e. the same as) the standard pneumatic data, the pneumatic data is normal, and the corresponding process equipment or electrical instrument equipment is normal in the operation state (for example, the pressure data is used for representing the internal pressure of the equipment) represented by the pneumatic data;
if the pneumatic data is not matched with (i.e. different from) the standard pneumatic data, it indicates that the pneumatic data is abnormal, and the operation state (for example, the pressure data is used for indicating the internal pressure of the equipment) indicated by the pneumatic data is abnormal when the pneumatic data is reflected on the corresponding process equipment or electrical instrument equipment.
The on-line detection unit 233 finally outputs a detection result including the comparison result for a user to check to determine whether the corresponding process equipment or electrical equipment is abnormal.

Specifically, the present embodiment is different from the previous embodiment in that a standard data range for each type of process equipment and electrical instrument equipment, respectively, is preset in the condition presetting unit 234 of the present embodiment. When the pneumatic data are in the corresponding standard data range, considering that the partial operation state of the process equipment or the electrical instrument equipment represented by the pneumatic data is normal; conversely, when the pneumatic data is not within the corresponding standard data range, it is considered that an abnormal condition occurs in the partial operation state of the process equipment or the electrical instrument equipment represented by the pneumatic data at that time.

In a preferred embodiment of the present invention, the data server 23 may include a plurality of display units (not shown), and each display unit is disposed in a corresponding one of the user terminals. In other words, in this embodiment, the data server 23 provides a plurality of user terminals, and each of the user terminals is used by a user to check a detection result of the online detection of the pneumatic data. The user terminal can also provide the user with an operation instruction sent to the on-site local control system through the data server so as to control the pneumatic transmission system. The user can optimize the operation of the pneumatic transmission system according to the detection result output by the online detection unit 233, thereby improving the stable operation of the pneumatic transmission system.
