Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be described in detail and completely with reference to the following specific embodiments of the present application and the accompanying drawings. It should be apparent that the described embodiments are only some of the embodiments of the present application, and not all of the embodiments. 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 application.
The embodiment of the invention provides an environment monitoring method and device.
First, an environment monitoring method provided in an embodiment of the present invention is described below.
It should be noted that the execution subject of the method provided in the embodiment of the present invention may be a mobile terminal, an industrial personal computer used in the industrial control field, and the mobile terminal may include: a mobile phone, a tablet computer, a personal digital assistant, etc., which are not limited in the embodiments of the present invention.
FIG. 1 is a flow chart of an environmental monitoring method according to an embodiment of the present invention, as shown in FIG. 1, the method includes the steps of:
in step 101, environmental monitoring is initiated.
The starting mode can be that the switch is manually started, the monitoring device starts to monitor the ambient temperature, or when a user opens the equipment in the factory to operate, the monitoring device is triggered to start to execute the related operation.
In step 102, the ambient temperature of each point to be monitored is obtained in real time, and the ambient temperature is measured by a temperature sensor.
In an industrial system, the temperature of equipment will rise during operation, and when the equipment is overloaded for a long time or works under high power, the temperature of the equipment rises more quickly, or when the equipment breaks down, the temperature of the equipment can be abnormally high, so whether the equipment has an abnormal condition or not is judged by monitoring the temperature of the equipment. Specifically, a temperature sensor is installed beside each device or pipeline to be monitored, the point of each installed temperature sensor is called as a point to be monitored, and the temperature sensor acquires the ambient temperature of each point to be monitored in real time.
In step 103, the obtained ambient temperature is compared with a standard database.
The comparison of the information needs a judgment standard or reference to know whether the information is normal or abnormal, so that the acquired environmental temperature is compared with a standard database.
In step 104, it is determined whether the ambient temperature is abnormal according to the comparison result.
Before the environmental monitoring is started, the method further comprises establishing a standard database, wherein the standard database is obtained by training the training samples by using a specific algorithm. The training samples may be ambient temperature data from the point to be monitored.
For ease of understanding, the environment monitoring process in this embodiment is described with reference to the flowchart of the standard data path establishing method shown in fig. 2. As shown in fig. 2, the method may include the steps of:
in step 201, an ambient temperature is acquired at first preset time intervals.
According to the clock signal, the output value of the temperature sensor at the monitoring point is acquired at intervals of a first preset time interval, the value of the first preset time interval can be set according to the actual situation, for example, the value can be 2 seconds, namely, the output value (temperature data) of the sensor is acquired at intervals of 2 seconds, and thus, the situation that the data are continuously acquired, and the calculation amount is increased can be avoided.
In steps 202 and 203, data screening is performed on the obtained ambient temperature, and the screened ambient temperature is stored in the standard database.
Because the acquired temperature data is used for establishing a standard database, and when the equipment machine is in operation, the temperature does not increase or decrease steeply under the normal operation condition, if such data occurs, the data is primarily screened and filtered, namely, an upper limit value and a lower limit value are set, and when the acquired temperature data is not between the upper limit value and the lower limit value, the data is abnormal data and is filtered, wherein the upper limit value and the lower limit value are preset, the upper limit value is greater than the lower limit value, the specific numerical value can be set according to historical data or empirical data, namely, under the normal condition, the environmental temperature cannot reach the value, so that the obvious abnormal data can be filtered, and the data accuracy of the standard database is ensured. Then comparing the temperature data obtained at present after the preliminary screening and filtering with the latest stored environmental temperature data in the preset database to obtain a deviation value, and if the deviation value is greater than a first threshold and smaller than a second threshold, storing the environmental temperature obtained at present; otherwise, the currently acquired ambient temperature is discarded. The environment temperature data stored in the initial preset database is the first environment temperature data after preliminary screening and filtering. The first threshold and the second threshold are preset, the second threshold is greater than the first threshold, the specific value is set according to actual needs, the smaller the first threshold is, the more accurate the data stored in the standard database is, and of course, the smaller the first threshold is, the larger the amount of data stored is, so that the specific needs are determined according to specific actual conditions. The setting of the second threshold value can further perform secondary screening on the data, because after the obtained current environmental temperature data is primarily screened, the data which are obviously abnormal are only filtered. In consideration of the fact that under normal conditions, in a short time, the difference between the environmental temperature data acquired at two adjacent moments is not too large, the second threshold is set so as to further ensure the objectivity and accuracy of the data in the standard database. Wherein the upper limit > the second threshold > the first threshold > the lower limit.
In addition, at intervals of a second preset time interval, the environment temperature obtained currently after the preliminary screening is directly stored in the standard database. The second predetermined time interval is greater than the first predetermined time interval. For example, the first predetermined time interval is 2s, and the second predetermined time interval is 5 mins.
In step 204, a temperature range is determined based on the data stored in the criteria database.
The maximum and minimum values are determined based on the ambient temperature data stored in the standard database, so that the temperature interval range can be determined.
Further, the temperature interval range in the standard database may be established based on each point to be monitored, that is, data in the establishment process of the standard database is derived from temperature data of each point to be monitored, and then a corresponding temperature interval range is established for each point to be monitored, at this time, a mapping relationship between each point to be monitored and the temperature interval range is stored in the standard database.
At this time, steps 103 and 104: comparing the obtained ambient temperature with a standard database; according to the comparison result, judging whether the environment temperature is abnormal, specifically:
when the acquired environmental temperature of the point to be monitored is not within the corresponding temperature range, judging that the environmental temperature of the point to be monitored is abnormal;
otherwise, judging that the ambient temperature of the point to be monitored is normal.
The invention also provides an environment monitoring method based on another embodiment of the standard database, as shown in fig. 3, the method may include the following steps:
in step 301, a curve relationship between the external environment temperature and the environment temperature of the point to be monitored is established based on historical data, and the curve relationship is stored in a standard database.
It is considered that the ambient temperature of the point to be measured will be affected when the ambient temperature is different. The external environment here generally refers to an environment outside a workshop for preventing equipment or a whole large environment, the external environment temperature can be measured by setting a temperature sensor in the external environment, or can be directly obtained from data of a certain weather forecast platform or an APP of weather forecast, and the accuracy is higher by adopting the temperature sensor to measure in real time. The point to be monitored can be understood as the ambient temperature beside the equipment of the machine or the ambient temperature beside the pipeline. When the external environment temperature changes, the environmental temperature of the point to be measured is bound to be influenced by the external environment temperature and changes along with the change under the condition that other conditions are not changed. Therefore, in order to improve the accuracy of the standard database and make a correct judgment, the corresponding relationship between the external environment temperature and the environment temperature of the point to be monitored needs to be established. Specifically, a curve relation between the outside ambient temperature and the ambient temperature of the point to be monitored is established by taking the outside ambient temperature as an X axis and the ambient temperature of the point to be monitored as a Y axis according to a large amount of historical data, namely the outside ambient temperature and the ambient temperature data of the point to be monitored.
In step 302, obtaining an ambient temperature; and determining the corresponding ambient temperature according to the obtained external ambient temperature and the curve relation.
After the standard database is established, when environment monitoring is formally started, the current external environment temperature is obtained, and the environment temperature of a point to be monitored under the external environment temperature is determined according to the external environment temperature and the curve relation. The determined environment temperature of the point to be monitored is a theoretically normal temperature value.
In step 303, it is determined whether a deviation value between the currently acquired ambient temperature of the point to be monitored and the determined ambient temperature is greater than a preset constant C.
The currently acquired environmental temperature of the point to be monitored and the determined environmental temperature are not in the same external environment in time, but at different moments, two temperature values are likely to be different, and a certain deviation value may appear, so that a common sense C is set, and then whether the deviation value is greater than the constant C is judged, if so, the difference between the two values is great, namely, the environmental temperature of the point to be monitored deviates from the standard value to be greater, and then the step 304 is performed: and judging that the ambient temperature of the current point to be measured is abnormal. The corresponding machine equipment or pipeline may be abnormal. When the deviation value does not exceed the constant, it indicates that the difference between the two values is small, i.e. the ambient temperature of the point to be measured is very close to the standard value, then step 305 is performed: and judging that the ambient temperature of the current point to be measured is normal. Therefore, the method has certain fault tolerance and better meets the actual requirement, so that the accuracy of the abnormity judgment can be ensured.
The invention also provides an environment monitoring method based on another embodiment of the standard database, wherein the standard database is established after environment monitoring is started. As shown in fig. 4, the method may include the steps of:
in step 401, classifying points to be monitored;
the points to be monitored can be classified according to historical data of the environmental temperature, namely the points to be monitored with the environmental temperature data closer to each other are taken as a class; the points to be monitored corresponding to the machine equipment with the same model can also be classified into one class, because if the models of the machines are the same, the temperatures generated during the operation of the machines are relatively close.
In step 402, it is determined whether the obtained ambient temperature change rate of the point to be detected is greater than the average change rate of the ambient temperature of all the points to be detected in the class.
When a certain machine equipment is abnormal or a certain section of pipeline occurs, the change rate of the temperature of the corresponding point to be monitored is changed suddenly, so that whether the abnormality occurs is judged according to the change rate of the environmental temperature, and the average change rate of the environmental temperature of all the points to be monitored in the type is used as a reference. When the obtained change rate of the environmental temperatures of the points to be detected is greater than the average change rate of the environmental temperatures of all the points to be detected in the category, the step 403 is executed; otherwise, go to step 404.
In step 403, it is determined whether a deviation value between the ambient temperature change rate of the point to be detected and the average change rate of the ambient temperatures of all the points to be detected in the class is greater than a third threshold.
If the judgment result is yes, that is, the change rate of the environmental temperature of the point to be detected obviously protrudes from the average change rate of the environmental temperatures of all the points to be detected in the category, then, go to step 405; otherwise, go to step 404.
In step 404, the ambient temperature of the point to be monitored is determined to be normal.
In step 405, it is determined that the ambient temperature of the point to be monitored is abnormal.
Further, the environment monitoring method further comprises: and when the environment temperature is judged to be abnormal, warning information is sent out.
The warning information may include position information of the point to be monitored, corresponding machine information or pipeline information, and temperature value or temperature change rate information. When the execution main body of the method is the industrial personal computer, after the warning information is displayed on the display screen of the mobile terminal, the user is reminded by vibration and/or music, and when the execution main body of the method is the industrial personal computer, after the warning information is displayed on the display screen of the industrial personal computer, the user is reminded by sound and/or light, so that the user can make adjustment in time according to the warning information.
