In view of the above technical problems, embodiments of the present invention provide a method and an apparatus for detecting a device state switching time, and an electronic device. In summary, the solution idea of the detection scheme for device state switching time provided by the embodiment of the present invention is as follows:
according to the scheme, the corresponding equipment information in the time interval to be detected is obtained, and the equipment information comprises the equipment yield and/or the equipment temperature corresponding to a plurality of moments in the time interval to be detected. Since the device yield and the device temperature corresponding to the multiple times can reflect the state of the device, the device state switching time corresponding to the process of switching the device from the first state to the second state can be detected from the multiple times based on the device yield and/or the device temperature corresponding to the multiple times, and the automatic detection of the device state switching time is realized. Through automatic detection of the equipment state switching moment, the actual operation time of the equipment can be determined, and the accuracy of a production index monitoring result is improved.
Having described the basic idea of a detection scheme for device state switching times, various non-limiting embodiments of the present invention are described in detail below.
The detection scheme of the device state switching time provided by the embodiment of the invention can be executed by an electronic device, and the electronic device can be a server. The server may be a physical server including an independent host, or may also be a virtual server carried by a host cluster, or may also be a cloud server. The electronic device may also be a terminal device such as a smartphone, tablet, PC, notebook, etc.
In practical applications, the electronic device may be a production line management device, for example, a device equipped with a Manufacturing Execution System (MES). The MES at least comprises a system maintenance end and a monitoring end for detecting the equipment state switching time. Optionally, the monitoring end may be implemented as a terminal application corresponding to each production process, or may also be implemented as an electronic billboard corresponding to each production process.
The detection scheme of the equipment state switching time provided by the embodiment of the invention is suitable for a scene of monitoring the running time of various product manufacturing equipment. In practical applications, various product manufacturing facilities are used, such as a bottled beer bottling line and a carbonated beverage bottling line. The bottled beer filling production line comprises a sterilizer.
The following describes the implementation of the method for detecting the device state switching time in conjunction with the following embodiments.
Fig. 1 is a flowchart of a method for detecting device state switching time according to an embodiment of the present invention, and as shown in fig. 1, the method includes the following steps:
101. and acquiring corresponding equipment information in a time period to be detected.
In the embodiment of the invention, in order to determine the actual operation time of the various product manufacturing devices, the actual operation states of the various product manufacturing devices need to be determined, so that the device information corresponding to the period to be detected needs to be acquired, and the subsequent detection is realized based on the device information.
In the embodiment of the invention, the equipment information comprises equipment yield and/or equipment temperature corresponding to a plurality of moments in the period to be detected. A plurality of moments, i.e. a plurality of points in time within the period to be detected. The production capacity of the apparatus corresponding to a plurality of times includes, for example, the production capacity corresponding to each time. The device temperatures corresponding to the plurality of times include, for example, device temperatures corresponding to the respective times. Equipment throughput and equipment temperature can vary as equipment conditions change. Optionally, the device information may also include a device identification, such as a production line identification.
For example, if the device is a bottled beer filling device, the device output corresponding to a plurality of times in the period to be detected may be the bottle discharge number corresponding to the plurality of times, and the device temperature corresponding to the plurality of times may be the sterilizer temperature corresponding to the plurality of times.
In an optional embodiment, in 101, the device information is periodically collected based on a preset period. At this time, the interval duration between the multiple times is the same, and the interval duration is determined by the preset period. For example, the preset period is 5 minutes.
For example, assuming that the device is a bottled beer filling device, the device information corresponding to the multiple times in the period to be detected includes the number of bottles discharged and the temperature of the sterilizer corresponding to the multiple times. A database table for storing the number of bottles discharged and the temperature of the sterilizing machine corresponding to a plurality of moments can be established in a database, the storage instruction is executed once every half hour, and the number of bottles discharged and the temperature of the sterilizing machine collected from bottled beer filling equipment are stored in the database table.
Alternatively, the average value of the difference between the number of bottles discharged in every 5 minutes and the average value of the temperature of the sterilizer in every 5 minutes of the bottled beer filling equipment are calculated, and then the data are stored in the database table every half hour.
The calculation process of the bottle number difference is as follows: suppose that the three equally spaced time points are time point a, time point b and time point c. Assuming that the number of bottles discharged at the time a is 100, the number of bottles discharged at the time b is 150 and the number of bottles discharged at the time b is 300, the difference between the number of bottles discharged at the time b and the number of bottles discharged at the time a is 50; the difference between the number of bottles discharged at the time c and the number of bottles discharged at the time b is 150. If the number of output bottles difference is null, the number of output bottles difference is recorded as 0 in the database table.
Optionally, the sterilization machine status can also be recorded in a database table so as to simplify the subsequent detection and judgment process. Specifically, if the sterilizer temperature is higher than or equal to a preset threshold (e.g., 50 degrees), the sterilizer temperature status is recorded as 1 in the database table. If the temperature of the sterilization machine is lower than the preset threshold value, the temperature state of the sterilization machine is recorded as 0 in the database table. In order to eliminate the interference of the abnormal condition on the detection process, if the temperature of the sterilization machine is a null value or is not in the range of 0-90 degrees, the temperature state of the sterilization machine is recorded as 0 in the database table.
In other plants than bottled beer filling plants, the plant output and the plant temperature may also be implemented as other data than the number of bottles output and the sterilizer temperature of the above examples. For example, the equipment temperature in the bottled milk production equipment is the temperature of the milk bottle disinfection equipment.
In practical applications, the device information is collected in real time by an Object Linking and embedding (OPC) technique applied to Process Control. OPC technology refers to a communication interface standard established between industrial control systems and applications. The technology provides a standard data access mechanism of an industrial control system, effectively separates hardware from application software, mainly solves the problem of data exchange between a process control system and a data source thereof, and can provide transparent data access among various applications.
After the device information corresponding to the period to be detected is obtained, the device state switching time can be detected based on the device information.
102. And detecting the equipment state switching time corresponding to the process of switching the equipment from the first state to the second state from the plurality of times based on the equipment yield and/or the equipment temperature corresponding to the plurality of times.
In the embodiment of the invention, the equipment state switching time comprises a shutdown time and a startup time. The shutdown time is a time corresponding to a process of switching the device from the running state to the shutdown state. The starting-up time is the time corresponding to the process of switching the equipment from the shutdown state to the running state.
For the shutdown time and the startup time, how to detect the device state switching time corresponding to the process of switching the device from the first state to the second state from multiple times will be described below in two cases:
the first condition is as follows: the first state is assumed to be an operating state, the second state is assumed to be a shutdown state, and the device state switching time comprises shutdown time.
In this case, the detection of the device state switching time corresponding to the process of switching the device from the first state to the second state from the plurality of times based on the device yield and/or the device temperature corresponding to the plurality of times may be implemented as the detection process shown in fig. 2, including the steps of:
201. and selecting a first moment from the plurality of moments based on the equipment temperatures corresponding to the plurality of moments.
The equipment temperature corresponding to the first moment is lower than the equipment temperature corresponding to the second moment, the equipment temperature corresponding to the first moment is lower than a first threshold, the equipment temperature corresponding to the second moment is higher than or equal to the first threshold, and the time sequence of the second moment is arranged in the front of the first moment.
For example, assuming that the device is a bottled beer filling device, the device output corresponding to a plurality of moments in the period to be detected includes the sterilization machine state corresponding to a plurality of moments, and the sterilization machine state is used for indicating the interval where the device temperature of the sterilization machine is located. Assuming that the sterilizer temperature is higher than or equal to 50 degrees (i.e., the above-mentioned first threshold), the sterilizer temperature status is recorded as 1; if the temperature of the sterilizer is lower than 50 ℃, the temperature state of the sterilizer is recorded as 0. Based on this, if it is detected that the difference between the sterilization machine temperature state corresponding to the time t and the sterilization machine temperature state corresponding to the previous time among the plurality of times is-1, that is, the sterilization machine state changes from 1 to 0, the time t is taken as the first time.
202. The method includes determining that the device is in a shutdown state for a first preset duration from a first time.
Specifically, if it is detected that the average value of the device temperatures corresponding to each time within a first preset time period from a first time is smaller than a second threshold, it is determined that the device is in a shutdown state within the first preset time period, where the second threshold is smaller than or equal to the first threshold.
For example, the first preset time period may be 8 hours. In order to improve the accuracy of the determination result, the second threshold should have a certain difference from the first threshold. For example, the first threshold is 50 degrees, the second threshold may be set to 44 degrees. In practical applications, the second threshold is determined according to different devices.
203. And selecting a third time as a shutdown time from the times prior to the first time in the time sequence based on the equipment yield corresponding to the plurality of times.
And the equipment yield corresponding to the third moment is equal to the equipment yield corresponding to the moment adjacent to the third moment, and the time sequence of the moment adjacent to the third moment is arranged at the front or the back of the third moment.
Specifically, the difference in the production capacity of the equipment corresponding to the time points that precede the first time point in the chronological order may be determined. Assuming that the time i is any one of the times prior to the first time in chronological order, the device production difference value corresponding to the time i is a difference between the device production corresponding to the time i and the device production corresponding to the time adjacent to the time i. And selecting a fourth moment with the shortest time interval with the first moment from at least one moment when the equipment yield difference is larger than the third threshold, further arranging the fourth moment and the first moment in a time sequence, and selecting the moment with the earliest time sequence and zero equipment yield difference as the third moment. Alternatively, assuming that the apparatus is a bottled beer filling apparatus, the apparatus yield difference may be implemented as a bottle number difference, and a bottle number difference of zero indicates that the bottle number of the apparatus has not changed at an adjacent time.
Case two: the first state is assumed to be a shutdown state, the second state is assumed to be an operation state, and the device state switching time includes a startup time.
In this case, the detection of the apparatus state switching time corresponding to the process of switching the apparatus from the first state to the second state from the plurality of times based on the apparatus yield and/or the apparatus temperature corresponding to the plurality of times may be implemented as the detection process shown in fig. 3, including the steps of:
301. and selecting a fifth moment from the plurality of moments based on the equipment temperatures corresponding to the plurality of moments.
The device temperature corresponding to the fifth moment is higher than the device temperature corresponding to the sixth moment, the device temperature corresponding to the fifth moment is higher than the first threshold, the device temperature corresponding to the sixth moment is lower than or equal to the first threshold, and the time sequence of the sixth moment is arranged in the front of the fifth moment.
For example, assuming that the device is a bottled beer filling device, the device output corresponding to a plurality of moments in the period to be detected includes the sterilization machine state corresponding to a plurality of moments, and the sterilization machine state is used for indicating the interval where the device temperature of the sterilization machine is located. Assuming that the sterilizer temperature is higher than or equal to 50 degrees (i.e., the above-mentioned first threshold), the sterilizer temperature status is recorded as 1; if the temperature of the sterilizer is lower than 50 ℃, the temperature state of the sterilizer is recorded as 0. Based on this, if it is detected that the difference between the sterilization machine temperature state corresponding to the time point p and the sterilization machine temperature state corresponding to the previous time point is 1, that is, the sterilization machine state changes from 0 to 1, the time point p is taken as the fifth time point.
302. And determining that the equipment is in the running state within a second preset time period from the fifth moment.
Specifically, if it is detected that the average value of the device temperatures corresponding to the times in the second preset time period is greater than the first threshold value, and the average value of the device yields corresponding to the times in the second preset time period is greater than the sixth threshold value, it is determined that the device is in the operating state in the second preset time period.
For example, assuming that the apparatus is a bottled beer filling apparatus, the apparatus output corresponding to a plurality of times within the period to be detected includes a bottle number difference and a sterilizer temperature corresponding to a plurality of times. The sixth threshold is assumed to be 500. The second predetermined duration is assumed to be 6 hours. And if the average value of the bottle number difference is larger than 500 and the temperature of the sterilizing machine is larger than 50 ℃ within 6 hours from the moment p, determining that the bottled beer filling equipment is in the operating state within 6 hours from the moment p.
303. And selecting a seventh moment from the moments after the fifth moment in time sequence as the starting moment based on the equipment yield and the equipment temperature corresponding to the moments.
The device yield difference corresponding to the seventh moment is larger than a fourth threshold, the device temperature corresponding to the seventh moment is larger than a fifth threshold, the time sequence of the moment adjacent to the seventh moment is arranged at the front position or the rear position of the seventh moment, and the fifth threshold is larger than or equal to the first threshold. Optionally, the sixth threshold is greater than the fourth threshold.
For example, assuming that the apparatus is a bottled beer filling apparatus, the apparatus output corresponding to a plurality of times within the period to be detected includes a bottle number difference and a sterilizer temperature corresponding to a plurality of times. The fourth threshold is assumed to be 100. The fifth threshold is assumed to be 55 degrees. And after the time p, taking the seventh time that the average value of the bottle number difference of the first bottle discharge is more than 100 and the temperature of the sterilizer is more than 55 degrees as the starting time.
It should be noted that the threshold and the threshold number are only one example provided in the present embodiment. In practical applications, the threshold value may be set according to a specific device or a specific production process.
Alternatively, after detecting a device state switching time corresponding to a process of switching the device from the first state to the second state from a plurality of times, the device state switching time may be stored. For example, it is still assumed that the device is a bottled beer filling device, and the device information corresponding to the multiple times in the period to be detected includes the number of bottles discharged and the temperature of the sterilizer corresponding to the multiple times. A database table for storing a plurality of device state switching times may be established in the database, the storage instruction of the device state switching times may be executed once per hour, and the device state switching times detected based on the number of bottles discharged and the temperature of the sterilizer may be stored in the database table. If the execution of the storage instruction fails, the related data at the equipment state switching moment should be cached in the local file, the related data in the local file is updated to the database after the abnormal recovery, the updated data in the local file is deleted, and the data loss is prevented. It can be understood that a corresponding relationship between a plurality of devices and respective device state switching moments can also be established, and the device state switching moments corresponding to the plurality of devices are stored in batches based on the corresponding relationship.
Further, the subsequent detection process may be based on the current device state switching time. Namely, the time interval between the previous time of switching the state of the device and the current time is taken as the time interval to be detected. And if the database table used for storing the plurality of equipment state switching moments is inquired, acquiring the last equipment state switching moment.
Optionally, a detailed log corresponding to a plurality of device state switching moments is obtained from the database, where the log includes query or storage instruction execution time and device information. If the query or store instruction fails to execute, the log may also record the reason for the failure.
In the execution process of the method for detecting the equipment state switching time shown in fig. 1, the equipment information corresponding to the time period to be detected is obtained, where the equipment information includes the equipment yield and/or the equipment temperature corresponding to the multiple times in the time period to be detected, and the equipment yield and the equipment temperature corresponding to the multiple times can reflect what state the equipment is in, so that the equipment state switching time corresponding to the process of switching the equipment from the first state to the second state is detected from the multiple times based on the equipment yield and/or the equipment temperature corresponding to the multiple times, thereby realizing automatic detection of the equipment state switching time, so as to determine the actual operation time of the equipment, and improve the accuracy of the production index monitoring result.
