For example, the target chromatographic monitoring data may be chromatographic monitoring data with preset conditions, for example, a plurality of chromatographic monitoring data arranged in time sequence on the same day or in the same week, and a fault is determined from the first data, so that when the chromatographic monitoring device fails, the chromatographic monitoring device can be quickly found to have a fault.

Illustratively, the preset fault conditions include a first fault condition, a second fault condition, a third fault condition, a fourth fault condition, and a fifth fault condition.

In some embodiments, the second fault condition is whether total hydrocarbon value data of each piece of chromatographic monitoring data is 0, the chromatographic monitoring data of the preset condition is a plurality of pieces of chromatographic monitoring data arranged in a time sequence, whether the plurality of pieces of chromatographic monitoring data meet the second fault condition is sequentially judged, and if one piece of chromatographic monitoring data meets the second fault condition, it is determined that the fault type is a non-software fault, and the fault type may be a chromatographic monitoring device hardware fault.

In some embodiments, the third fault condition is whether all the component data and the total hydrocarbon value data of each piece of chromatographic monitoring data are 99999 or-99999, the chromatographic monitoring data of the preset condition is a plurality of pieces of chromatographic monitoring data arranged in time sequence, whether all the plurality of pieces of chromatographic monitoring data satisfy the third fault condition is sequentially determined, and if one piece of chromatographic monitoring data satisfies the third fault condition, the fault type is determined to be a software fault, and the fault type may be a device shutdown or a software fault.

In some embodiments, the fourth fault condition is whether data interruption of a certain component or multiple components exists in chromatographic monitoring data meeting a preset condition, the chromatographic monitoring data meeting the preset condition is multiple chromatographic monitoring data arranged according to a time sequence, if a certain component of the multiple data corresponding to multiple time points is missing, the group of chromatographic monitoring data is judged to meet the fourth fault condition, the fault type is determined to be a non-software fault, and the fault type may be a sensor fault or a communication fault.

Step 103: and if the fault type of the chromatographic monitoring device is a software fault, the server sends a software reinstallation instruction to reinstall the software of the chromatographic monitoring device.

In some embodiments, the server sends a software reinstallation instruction to reinstall software of the chromatography monitoring device, the fault category of which is determined to be the software fault, acquires chromatography monitoring data at preset time intervals to conduct fault determination again after the reinstallation is completed, and if the chromatography monitoring data after the reinstallation determines that the software fault still exists, determines that the fault type of the chromatography monitoring device is device outage, generates fault maintenance information and sends the fault maintenance information to a fault maintenance worker.

Step 104: and if the fault type of the chromatographic monitoring device is a non-software fault, generating fault maintenance information according to the fault type and sending the fault maintenance information to a fault maintenance worker.

In some embodiments, the internal storage space of the chromatography monitoring apparatus comprises an application installation space and a local storage space, wherein the internal storage space refers to a storage area for storing user data, and the application installation space refers to a storage area for storing an application. When the space required by a new version of an application program is enlarged relative to the space required by an old version of an operating system, upgrades to the application program may not be completed. Based on the above, if the application program installation space is smaller than the installation space required by the new version application program, the size of the subspace requested from the local storage space is determined according to the difference value between the installation space required by the new version application program and the application program installation space. For example, if the size of the storage space required by the new version program is a and the size of the installation space of the application program is b, the requested subspace should be greater than or equal to the difference a-b between the storage space and the installation space of the application program.

And generating a space application instruction and an installation instruction according to the size of the subspace requested from the local storage space. The space application command is used for applying a subspace with the same size as the difference value from the space in which the data is not written in the local storage space. And combining the subspace and the application program installation space through a Device Mapper technology, and upgrading the application.

Specifically, the address of the local memory space partition is modified, and the subspace is moved out of the local memory space partition, so that the data of the application program in the subspace is prevented from being lost.

According to the monitoring method of the chromatographic monitoring device, a user can monitor the monitoring data uploaded by the plurality of chromatographic monitoring devices through the server to determine whether a fault occurs, and if the chromatographic monitoring devices have faults, the fault type is judged according to the monitoring data to be disposed. In addition, the server can also update or upgrade the local application programs of a plurality of chromatographic monitoring devices, and the management efficiency is improved.
