Description

Technical Field

[0001] The present invention relates to the field of computer technology, and particularly relates to a multi-channel device status visual tracking display device. Background Art

[0002] In the process of normal industrial automation pipeline operation, a production line is composed of multiple independent workstations, and each independent workstation contains one or more automated production devices. Whether the operating status of each device is normal will affect the operation of the entire production line and the production of products. Therefore, it is crucial to monitor whether the operating status of each device on the production line is normal.

[0003] Generally, the system records the device status changes in the form of logs, and judges whether the device operating status is abnormal by analyzing the error logs. However, when using traditional log analysis to analyze the device status, manual analysis of the original logs is often used, and the work efficiency is very low. And when the log data volume is large, the manual analysis workload is too large, and only a very small sample of sampling analysis can be carried out when problems occur, and it is impossible to carry out manual analysis one by one.

[0004] In view of the above problems, CN201510407888.5 discloses a method for visual parsing of fault data based on numerical control system logs (authorized after examination), which can perform visual parsing processing on the fault data of the numerical control system. But this technology has the following problems: This method only realizes the visual monitoring of the fault status of a single numerically controlled machine tool operation.

[0005] However, some workstations on the production line may contain devices with multi-channel parallel operations, and during different stages of the entire operation process of these devices, there are not only two states of "normal / fault", but also different device states. Normal situations such as: "waiting", "initializing", "working", "resetting", etc.; abnormal situations such as: "disconnected", "error", etc. The different working states of these devices in the time dimension (such as: start / stop / duration) are also the key points for monitoring whether the device is operating normally. At present, there is no intuitive analysis of the status of each device state in the time dimension (such as: start / stop / duration). For multi-channel parallel devices at the same workstation, when we want to analyze the correlation between multi-channel devices in the time dimension, at present, in addition to manually comparing logs or log analysis tables, there is no more intuitive analysis method. Summary of the Invention

[0006] In order to solve the above technical problems, the present invention provides a multi-channel device status visual tracking display device, which can visually display multi-channel devices on the same interface, facilitating intuitive observation of the device operating status. At the same time, it can intuitively compare the correlation between the statuses of multi-channel parallel devices in the time dimension on the same time axis.

[0007] To this end, the technical solution of the present invention is as follows:

[0008] A multi-channel device status visualization tracking display device, wherein the statuses of the multi-channel devices are all controlled by a centralized control module;

[0009] It includes a device information acquisition module, a log recording module, a log analysis module, and a visualization module;

[0010] The device information acquisition module is electrically connected to the centralized control module, collects the action signals of all devices according to time, and sends the action occurrence time and the device action signals to the log recording module together;

[0011] The log recording module is electrically connected to the device information acquisition module and can record the devices and their actions according to the action occurrence time;

[0012] The log analysis module is electrically connected to the log recording module. After obtaining the action occurrence time, device and device action information from the log recording module, it summarizes the device action information of the same device in chronological order and then transmits it outward;

[0013] The visualization module draws a graph with time as the axis for the received information. It can display the statuses of the same device at different time points in a graphical form, and the same status of the same device is displayed as the same graph.

[0014] Furthermore, the visualization module can display the statuses of different devices at the same time point in a certain sequence on the same graph with time as the axis.

[0015] Furthermore, it further includes a storage module, which is respectively connected to the log analysis module and the visualization module. It is used to store the action information and action occurrence time of the same device obtained from the log analysis module; the visualization module is used to draw a graph with time as the axis for the information obtained from the storage module.

[0016] Furthermore, the log analysis module can identify the abnormal status of the device and transmit it outward; after the visualization module obtains the information of the device abnormal status, at the time point when the device abnormal status appears, it can mark the device abnormal status with an obvious identifier different from other positions of the image.

[0017] Furthermore, the visualization module draws the devices belonging to the same path in the same area with time as the axis.

[0018] Furthermore, when the log analysis module summarizes the device action information: the time span between two actions when the device maintains the same state is considered as the device state maintenance time.

[0019] Furthermore, the visualization module displays the statuses of different time spans and different devices by scrolling along the time axis.

[0020] The present invention provides a multi-channel device status visual tracking display device for multi-channel devices at workstations on an automated industrial production line. It solves the problems that in traditional device status inspections, manual analysis of device system logs is inefficient, the large amount of log data makes it difficult for manual analysis to comprehensively cover all cases, and only sampling analysis can be carried out. It also solves the problem that it is impossible to directly analyze the correlation between the statuses of multi-channel parallel devices in the time dimension by viewing the logs.

[0021] Based on the agreed device status log recording rules, the present invention can visually display the device status, enabling users to directly detect and analyze the device operation status through a visual interface, and can directly compare the correlation between the statuses of multi-channel parallel devices in the time dimension on the same time axis.

[0024] The technical solution of the present invention will be described in detail below in conjunction with the drawings and specific embodiments.

[0025] A multi-channel device status visual tracking display device, where the statuses of multi-channel devices are all controlled by a centralized control module;

[0026] It includes a device information acquisition module, a log recording module, a log analysis module, and a visualization module;

[0027] The device information acquisition module is electrically connected to the centralized control module, collects the action signals of all devices according to time, and sends the action occurrence time and the device action signals to the log recording module together;

[0028] The log recording module is electrically connected to the device information acquisition module and can record the devices and their actions according to the action occurrence time;

[0029] The log analysis module is electrically connected to the log recording module. After obtaining the information of the action occurrence time, device, and device action from the log recording module, it summarizes the device action information of the same device in chronological order and then transmits it outward. As an implementation manner of the present invention, when the log analysis module summarizes the device action information: the time span between two actions of the device maintained in the same state is considered the device state maintenance time. For example, the time span between the camera starting the image acquisition signal and the camera successfully acquiring the image signal is recorded as the maintenance time of the camera in the image acquisition state.

[0030] The visualization module draws a graph with time as the axis for the received information. It can display the states of the same device at different time points in a graphical form, and the same state of the same device is displayed as the same graph. The time span between the camera starting the image acquisition signal and the camera successfully acquiring the image signal is displayed as the same graph on the image.

[0031] For the convenience of the inspectors to observe, the visualization module can display the states of different devices at the same time point in a certain sequence on the same graph with time as the axis.

[0032] The multi-channel device state visualization tracking display device provided by the present invention can display the device state in real time or be used during the data analysis process by the inspectors after collecting the data. It also includes a storage module, which is respectively connected to the log analysis module and the visualization module. It is used to store the action information and action occurrence time of the same device obtained from the log analysis module. The visualization module is used to draw a graph with time as the axis for the information obtained from the storage module.

[0033] For the convenience of viewing the abnormal state, the log analysis module can identify the device abnormal state and transmit it outward. After the visualization module obtains the information of the device abnormal state, at the time point when the device abnormal state appears, it can mark the device abnormal state with an obvious identifier different from other positions of the image.

[0034] For the convenience of observing the states of all devices on the same path, the visualization module draws the devices belonging to the same path in the same area with time as the axis.

[0035] For the clear observation of the device states in different time periods, the visualization module scrolls to display the states of different time spans and different devices with time as the axis.

[0036] As an implementation manner of the present invention, when the log analysis module summarizes the device action information: the time span between two actions of the device maintained in the same state is considered the device state maintenance time.
