Detailed Description
The technical solutions of the present invention will be described clearly and completely with reference to the accompanying drawings, and it should be understood that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In the description of the present invention, it should be noted that the terms "first", "second", and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.
In addition, the technical features involved in the different embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
The embodiment of the invention provides a method for discriminating monitoring data of a laboratory instrument, which comprises the following steps of:
step S101, receiving a plurality of detection signals sent by a plurality of sensors installed in a laboratory and used for detecting the state of the experimental instrument.
The experimental instrument and the user have necessary interaction, and when some important actions occur or the state changes, the experimental instrument can send signals to the user in a simple and direct-white mode, so that the user can quickly and smoothly know the information. This process is usually noticeable by some indicator light, warning sound, arrival of the component at a designated location, etc., which the user sees or hears to react to immediately. These simple, straight-white, obvious information can be sensed by conventional general-purpose sensors, such as: the indicator light can be sensed by a photoresistor, the alarm sound can be measured by a sound sensor or a decibel meter, the arrival of a specific position can be sensed by a proximity switch or a microswitch and the like. In the embodiment of the invention, the sensor is adopted to detect and collect various information of the experimental instrument, and the collected signal is sent to the background to be identified and recorded.
Step S102, identifying sensor information corresponding to each detection signal, and determining an event corresponding to each detection signal, wherein the event represents an event occurring in a laboratory and detected by a plurality of sensors.
For receiving the detection signal, the background needs to identify sensor information, such as information of a sensor type, a detection object, and the like, and then determine a current event corresponding to the detection signal based on the identified sensor information, that is, an occurrence event of the detection object of the current sensor, such as on-machine, off-machine, X-ray on, safety door off, and the like.
Optionally, in this embodiment of the present invention, identifying sensor information corresponding to each of the detection signals includes: acquiring a sensor number of a sensor corresponding to each detection signal; and determining a sensor code corresponding to the sensor number and the experimental instrument detected by the sensor through a table look-up, wherein the sensor code is used for indicating the type of the sensor.
In the embodiment of the invention, a corresponding sensor number and a sensor code are preset for each sensor. The sensor number is a unique identification code for the sensor and may be represented by a string of characters or numbers, such as 0104130425587. The sensor code is a sensor indicating the type of sensor, for example, a sensor coded "kaiguan" as a detection switch. Because the sensor information corresponds to the detected experimental instrument and is recorded in the information comparison table in advance, after the information of the sensor is determined, the corresponding experimental instrument and various other information can be determined in a table look-up mode.
Further optionally, in the embodiment of the present invention, one experimental apparatus corresponds to a plurality of sensors, the plurality of sensors are respectively used for detecting different components of the experimental apparatus, and after determining, by looking up a table, a sensor code corresponding to the sensor number and the experimental apparatus detected by the sensor, the method further includes: and inquiring the part of the experimental instrument corresponding to the sensor number to determine the detection object of the sensor.
In the embodiment of the invention, different parts of the experimental instrument, such as different parts of a safety door, an X-ray light pipe and the like in the powder X-ray diffractometer, are respectively detected, so that each detection result can be timely identified and recorded when a specific event occurs.
Further optionally, in this embodiment of the present invention, determining a current event corresponding to the detection signal includes: identifying a state value in the detection signal, the state value being indicative of a signal state detected by the sensor; and determining the current event state of the detection object of the sensor based on the state value.
The switch member indicates that the switch is on when the state value is 1, and indicates that the switch is off when the state value is 0. Similarly, the operation is indicated when the state value is 1, and the stop is indicated when the state value is 0. In the embodiment of the invention, the detection signal carries the state value to represent the working condition of the corresponding component, and the running condition of the instrument can be simply and clearly represented. Specifically, for the above state value, it can be determined by an analog signal of high and low levels at the time of detection by the sensor.
And step S103, recording the occurrence time corresponding to each event.
And step S104, judging whether the occurrence time sequence corresponding to all the events accords with the logic sequence used by the experimental instrument.
And step S105, when the occurrence time corresponding to the event does not accord with the logic sequence, determining that the monitoring data of the experimental instrument is abnormal. And when the logical sequence is met, no other operation is performed or the data is obtained again for further discrimination. The abnormality in the embodiment of the invention can be an abnormal state caused by the abnormal working of the instrument itself and caused by the artificial misoperation or the self fault of the instrument, can also be caused by objective reasons such as the error of monitoring data record, subjective artificial 'fake', sensor fault and the like.
In the using process of the experimental instrument, the experimental instrument has a certain operation logic sequence, for example, the experimental instrument is started up firstly and then is shut down. When the comprehensive judgment is carried out on all the time, if the data are found not to conform to the logic sequence, the monitoring data can be considered to be abnormal. It should be noted that, the determining of the abnormality in the embodiment of the present invention refers to a determination result in the machine recognition process, and whether the abnormality is caused needs to be finally determined after a worker analyzes specific data.
According to the embodiment of the invention, the detection signals are received, the sensor information corresponding to each detection signal is identified, the event corresponding to each detection signal is determined, the occurrence time corresponding to each event is recorded, whether the occurrence time sequence corresponding to all events accords with the logic sequence used by the experimental instrument is judged, when the occurrence time corresponding to the events does not accord with the logic sequence, the monitoring data corresponding to the experimental instrument is determined to be abnormal, and whether the occurrence time of each event accords with the logic is judged by utilizing the logic sequence between all events, so that the monitoring data with the abnormal occurrence is discriminated.
As an optional implementation manner, in the embodiment of the present invention, determining whether occurrence time sequences corresponding to all events conform to a logic sequence used by the experimental apparatus includes:
step S1, for all events, judging whether the occurrence time corresponding to the ith event and the occurrence time corresponding to the ith-j event accord with the logic sequence; judging whether the time difference between the ith event and the ith-j event meets a preset condition or not; j is 1 to m-1, wherein m represents the total number of events;
step S2, when the occurrence time corresponding to the ith event and the occurrence time corresponding to the ith-j event accord with the logic sequence; when the time difference between the ith event and the ith-j event meets the preset condition, adding 1 to the value of i;
step S3, when the occurrence time corresponding to the ith event and the occurrence time corresponding to the ith-j event do not conform to the logic sequence; or when the time difference between the ith event and the ith-j event does not meet the preset condition, determining that the monitoring data of the ith-j event is abnormal.
In the embodiment of the invention, all event occurrences are arranged in the system according to the time sequence, and when data discrimination is carried out, two adjacent or nonadjacent events (namely an ith event and an ith-j event) are adopted to carry out judgment one by one, and the logic sequence and the interval duration between the two events are respectively judged. For example, X-ray operation can only be started after power-on, and the start of X-ray operation requires power-on for a while, which is necessarily accompanied by X-ray shutdown (although X-ray shutdown may not be immediately after the X-ray operation event, and may be the m-th record after X-ray operation), which is necessarily after X-ray shutdown.
According to the embodiment of the invention, the specific position of the abnormal monitoring data can be accurately analyzed by judging the logic sequence and the time interval before the two events, so that the abnormal data can be accurately positioned.
In the above embodiment, when it is determined that the monitored data is abnormal, the subsequent determination process may be directly stopped, so that the calculation amount and performance consumption of the system may be reduced. Of course, the method can also be stopped after all the data are judged, so that all the abnormal data can be accurately found.
In the foregoing embodiment, since the logic sequence of event occurrences is basically fixed, however, the determination of the event interval needs to be distinguished according to specific events, specifically, the determining whether the time difference between the ith event and the ith-j event meets the preset condition includes: judging whether the time difference between the ith event and the ith-j event is greater than a first time threshold value; or judging whether the time difference between the ith event and the ith-j event is smaller than a second time threshold.
In the embodiment of the invention, different time thresholds can be set for different times to judge the time interval between events, so that the accuracy of data discrimination is improved.
As another optional implementation manner of the embodiment of the present invention, in the embodiment of the present invention, determining whether occurrence time sequences corresponding to all events conform to a logic sequence used by the experimental apparatus includes: judging whether the time sequence of the occurrence of different events of the same part of the experimental instrument accords with the operation sequence or not; and judging whether the time sequence of the event occurrence of different parts of the experimental instrument accords with the operation sequence.
In the process of judging the event, the operation sequence of the event between different components and the operation sequence of the same component at different time can be respectively judged, for example, the same component is started and closed, and the X-ray work can be started after the cabin door is closed.
Because the operation flow of the experimental instrument is basically fixed, in the embodiment of the invention, the corresponding operation sequence judgment logic can be set according to different experimental instruments, thereby aiming at different experimental instruments additionally.
As an optional implementation manner, in an embodiment of the present invention, after identifying sensor information corresponding to each of the detection signals and determining an event corresponding to each of the detection signals, the method further includes: starting a monitoring device for monitoring and recording the event; and controlling the monitoring device to monitor the occurrence process of the event to obtain a record file.
The embodiment of the invention also records the event process which occurs when the user uses the experimental instrument, and the record file can be a log file or a video file. If the video file is the video file, the corresponding monitoring device is a camera, if the video file is the log file, the corresponding monitoring device can be a log recording module, and the specific occurrence process of the current event can be accurately determined and known through the log file, so that subsequent checking and fault positioning are facilitated.
In the embodiment of the invention, the event process occurring in the laboratory can be recorded by acquiring the screen recording file when the user uses the instrument and the equipment, namely the video file acquired by screen recording, through the client software deployed on the computer, and the method and the device are mainly used for recording the relevant operations of the user using the equipment such as the computer in the laboratory.
Further optionally, in this embodiment of the present invention, the recording file is a video file, the monitoring device is a camera, and after controlling the monitoring device to monitor the occurrence process of the event and obtain the recording file, the method further includes: receiving a playback request for the video file; playing the video file; or, receiving a deletion request of the video file; and deleting the video file.
In the embodiment of the invention, for the recorded video file, a user can review the video file by revisiting to check the using condition of the experimental instrument, and for the normal using condition, a maintainer can also delete the corresponding file.
For the embodiment of the present invention, the following application scenarios are adopted for explanation:
