Please refer to fig. 1, which is a flowchart illustrating an apparatus operation control method according to an embodiment of the present invention.
An apparatus operation control method comprising a part or all of the steps of:
s100: the method includes the steps of obtaining first preset time of first equipment.
In this embodiment, the first device has a plurality of operating state parameters, the first preset time is a parameter of one of the operating times of the first device, and the first preset time is a time from a first occurrence of a peak load to a last occurrence of the peak load during an operating process of the first device, so that the first preset time is a time when a large active power occurs in the first device. Wherein the peak load is an active power which is 2 to 3 times greater than the average active power of the first device, the active power being in positive correlation with the operating current of the device again, i.e. an increase in the operating current of the device leads to an increase in the active power.
S200: and detecting whether the running time of the first equipment is greater than or equal to the first preset time.
In this embodiment, the first preset time is a part of the whole operation process of the first device, and since the active power of the first device is lower than the corresponding active power of the first device at the time of the peak load in the start stage and the end stage in the operation process of the first device, the first preset time is located in the middle of the operation duration of the first device. In this way, the first preset time of the first equipment in the operation process is used as a reference standard for starting the operation of the second equipment, so that the starting operation moments of the first equipment and the second equipment are different, and the subsequent peak load time of the first equipment is staggered with the peak load time of the first equipment.
S300: and when the running time of the first equipment is greater than or equal to the first preset time, starting and running second equipment.
In this embodiment, the first device and the second device are devices belonging to the same type, so that a time curve corresponding to a peak load of the second device is the same as a time curve corresponding to a peak load of the first device. In order to avoid the peak load overlap of the first device and the second device, that is, avoid the transient current caused by the impact current of the first device and the second device overlapping each other at the same time from being too large, the starting time of the second device is determined according to the magnitude relation between the operation time length of the first device and the first preset time, for example, when the operation time length of the first device is greater than or equal to the first preset time, the second device starts to start. Therefore, the time period of the second equipment when the peak load occurs is staggered with the time period of the first equipment when the peak load occurs, the impact current of the first equipment and the impact current of the second equipment are prevented from being superposed in the same time, the situation that the instantaneous current is overlarge when the first equipment and the second equipment work simultaneously is avoided, and the service life of the equipment is prolonged.
Moreover, when the number of the devices to be operated is multiple, the first device and the second device are relatively speaking, that is, the second device of this time can be used as the first device of the device to be operated next, that is, the second device is equivalent to the first device relative to the next device, so that each device to be operated can determine the start operation time only by acquiring the first preset time of the previous device, so that the peak load time of the devices is staggered when the devices are operated simultaneously, and the situation that the instantaneous current is overlarge when the devices are operated simultaneously is avoided.
In the above embodiment, the first preset time of the first device is obtained in real time, and is compared with the time length for starting the operation, and the second device is started only when the operation time length is greater than the first preset time, so that the time period for the peak load of the second device to appear is staggered with the time period for the peak load of the first device, that is, the over-high impact current is avoided when the first device and the second device operate simultaneously, and the service life of the device is prolonged. Moreover, when the second device is started to operate, the first device is also in an operating state, and as a time difference exists between the starting time of the first device and the starting time of the second device, namely the starting time of the second device is later than the starting time of the first device, the time period of the peak load of the first device is different from the time period of the peak load of the second device, so that the time period of the peak load of the first device is prevented from being staggered with the time period of the peak load of the second device, the situation that the instantaneous current is too large when the devices work simultaneously is avoided, and the service life of the devices is prolonged.
In an embodiment, the obtaining the first preset time of the first device includes: starting the first equipment, and acquiring an operation state parameter of the first equipment in an operation period; updating a first preset time of the first equipment according to the running state parameter, wherein the first preset time is the duration time that the running state parameter of the first equipment is greater than a preset running state parameter; at the end of the operational period, shutting down the first device. In this embodiment, the first device and the second device are the same type of device, and have the same operation state parameters in their respective operation periods, that is, the curves corresponding to the operation parameters are the same. Before starting operation of each device on the production line, especially before starting the same type of device on the production line, it is necessary to perform individual detection on the first device to be started, and detect the operating state of the first device in a single operating cycle, that is, to obtain the operating state parameter of the first device in one operating cycle. In an operation cycle of the first device, the operation state parameter of the first device changes with time, when the operation state parameter of the first device is greater than or equal to a preset operation state parameter, it indicates that a peak load operation state occurs in the operation state of the first device, and the duration of the peak load operation state of the first device is set as the first preset time, where the first preset time is the duration of the operation of the first device in the peak load operation state. The preset operation state parameter is used as a basis for judging whether the first device enters or exits the peak load operation state, for example, before a first preset time for updating the first device according to the operation state parameter, the method includes: when the running state parameter of the first equipment is larger than a preset running state parameter, acquiring first time; when the running state parameter of the first equipment is smaller than the preset running state parameter, acquiring second time; and acquiring the first preset time according to the first time and the second time. The first preset time is a difference value between the first time and the second time, that is, the first preset time is a difference value obtained by subtracting the first time from the second time. The first device has multiple state parameters during operation, important parameters of the first device are obtained after analysis and processing according to the operation parameters of the first device, and accordingly the first preset time of the first device can be conveniently determined subsequently through the parameters.
In another embodiment, when the second device and the first device are different types of devices, that is, when the types of the second device and subsequently turned on devices are different from the type of the first device, the second device is subjected to the individual detection of the first device in the above embodiments to obtain the first preset time of the second device, that is, to obtain the peak load operation time of the second device, so as to facilitate the subsequent turning on of the devices of the same type as the second device, thereby facilitating the turning on operation of the different types of devices on the whole production line, so as to reduce the inrush current during operation, and prolong the service life of the devices.
In an embodiment, the operating state parameter of the first device comprises at least one of an operating current, an operating voltage and an active power of the first device. In this embodiment, the active power of the first device is obtained according to the working current and the working voltage of the first device, where the working current and the working voltage of the first device are both time-varying curves, so that the active power of the first device is an active power curve of the first device transformed over time, that is, the active power parameter of the first device is a function of the active power of the first device and time, that is, the active power parameter of the first device includes an active power value of the first device and a corresponding time value. Thus, the first preset time of the first device is determined according to the active power of the first device.
Moreover, the active power of the first device is obtained according to the working current and the working voltage of the first device, that is, the active power of the first device is composed of the working current and the working voltage of the first device, that is, the active power of the first device and the relation between the working current of the first device are positively correlated, so that the magnitude of the current of the first device is reflected by the magnitude of the active power of the first device, the time of the occurrence of the impact current of the first device is conveniently determined by the active power of the first device, and the first preset time of the first device is conveniently determined.
In an embodiment, the obtaining the first preset time of the first device further includes, before the obtaining the first preset time of the first device: acquiring the accumulated running number of the equipment; and adjusting the running state of the first equipment according to the accumulated running number. Because the number of the devices of the same type which operate simultaneously has an upper limit, the accumulated operation number is the sum of the number of the first devices and the number of the devices which operate before, and the situation that the peak load time generated when the devices exceeding the number of the same type operate overlaps with the peak load time of the devices before is avoided by accumulating the operation total number of the devices. The upper limit of the number of the devices of the same type which are operated simultaneously is determined according to the operation state of the devices, namely according to the duration time of different states corresponding to the active power curve of the devices.
In an embodiment, the obtaining of the first preset time of the first device includes: acquiring a second running time of the first equipment; acquiring a first running number according to the first preset time and the second running time; and adjusting the operation state of the first equipment according to the first operation number. The second operation time is determined according to the active power curve of the first device, and the second operation time is a time period from the beginning of the operation of the first device to the first occurrence of the peak load of the first device, that is, the second operation time is before the first preset time, that is, the operation process of the first device enters the first preset time after the end of the second operation time, that is, the first preset time and the second operation time are continuous in the time dimension. The accumulated operation quantity of the equipment is related to the second operation time, the first operation quantity is calculated according to the first preset time and the second operation time, the first operation quantity is a standard for judging whether the total quantity of the current equipment exceeds an upper limit, the condition of the total quantity of the current equipment operation is conveniently determined according to the size relation between the accumulated operation quantity and the first operation quantity, and then whether the first equipment needs to be closed is conveniently determined.
In an embodiment, the obtaining a first operation number according to the first preset time and the second operation time includes: acquiring a first operation value according to the ratio of the first preset time to the second operation time; taking an integer portion of the first running value as the first running number. Since the number of devices operating is a natural number, in this embodiment, the first number of operations also needs to be rounded. Firstly, carrying out quotient operation on the second operation time and the first preset time, namely the second operation time is used as dividend, the first preset time is used as divisor, so that the quotient between the second operation time and the first preset time is used as the first operation value, and the first operation value is decimal in most cases, namely the first operation value is non-integer; and finally, rounding the first operation value, namely only reserving an integer part of the first operation value, and taking a rounded value of the first operation value as the first operation quantity, namely the first operation quantity is the lower rounding of the first operation value, namely the first operation quantity is smaller than the first operation value. Therefore, the first operation quantity is a value obtained after the quotient is obtained and rounded between the second operation time and the first preset time, the follow-up comparison between the first operation quantity and the accumulated operation quantity is facilitated, and the total quantity of the currently operated equipment is prevented from exceeding the upper limit of the operation quantity.
In an embodiment, the obtaining the first running number according to the first preset time and the second running time includes: detecting whether the accumulated running number is smaller than the first running number; and when the accumulated operation number is smaller than the first operation number, starting the first equipment. The first operation quantity is determined by the operation state parameter of the first device, that is, when the model of the first device is determined, the first operation quantity of the first device is fixed, and the accumulated operation quantity is a total value of accumulating the first device and the devices which are started to operate, that is, the accumulated operation quantity is changed along with the change of time, so that whether the first device exceeds the operation quantity upper limit of the device is determined by comparing the accumulated operation quantity with the first operation quantity. In this embodiment, when the accumulated operation number is smaller than the first operation number, the accumulated operation total number of the devices does not exceed the first operation number, so that the devices which are started before are not affected after the first devices are started, and the situation that the instantaneous current is too large when the devices work simultaneously is avoided.
In an embodiment, the detecting whether the accumulated running number is smaller than the first running number further includes: and when the accumulated operation number is greater than or equal to the first operation number, closing the first equipment. The accumulated operation quantity is the total quantity of the devices which are statistically operated, the first operation quantity is the upper limit of the operation quantity of the devices, and whether the quantity of the devices which are currently operated exceeds the upper limit is determined by comparing the accumulated operation quantity with the first operation quantity. In this embodiment, when the cumulative operating number is greater than or equal to the first operating number, that is, the total number of currently operating devices has reached the upper limit of the operable number of devices, turning on the first device again inevitably causes the first device to affect the operation of the previous device, that is, the peak load time of the first device may overlap with the peak load time of one of the previous devices, and in order to avoid the above situation, the first device is not turned on.
In an embodiment, the obtaining of the first preset time of the first device further includes: acquiring a third running time of the first equipment; acquiring a second operation quantity according to the first preset time and the third operation time; and adjusting the operation state of the first equipment according to the second operation number. The third operation time is also determined according to the active power curve of the first device, and the third operation time is a time period from the last occurrence of the peak load of the first device to the time when the first device is turned off, that is, the third operation time is located after the first preset time, that is, the operation process of the first device enters the third operation time after the first preset time is ended, that is, the first preset time and the third operation time are continuous in the time dimension. The accumulated operation quantity of the equipment is related to the third operation time, the second operation quantity is calculated according to the first preset time and the third operation time, the second operation quantity is also a standard for judging whether the total quantity of the current equipment exceeds an upper limit or not by the first equipment, the condition of the total quantity of the current equipment operation is conveniently determined according to the size relation between the accumulated operation quantity and the second operation quantity, and then whether the first equipment needs to be closed or not is conveniently determined.
In an embodiment, the obtaining a second operation number according to the first preset time and the third operation time includes: acquiring a second operation value according to the ratio of the first preset time to the third operation time; taking an integer portion of the second running value as the second running number. Since the number of devices operating is a natural number, in this embodiment, the second number of devices also needs to be rounded. Firstly, carrying out quotient operation on the third running time and the first preset time, namely the third running time is used as a dividend, the first preset time is used as a divisor, so that the quotient between the third running time and the first preset time is used as the second running value, and the second running value is decimal in most cases, namely the second running value is a non-integer; and finally, rounding the second operation value, namely only reserving an integer part of the second operation value, and taking a rounded numerical value of the second operation value as the second operation quantity, namely the second operation quantity is the lower rounding of the second operation value, namely the second operation quantity is smaller than the second operation value. Therefore, the second operation quantity is a value obtained by quotient calculation and rounding of the third operation time and the first preset time, so that the follow-up comparison of the second operation quantity and the accumulated operation quantity is facilitated, and the total quantity of the currently operated equipment is prevented from exceeding the upper limit of the operation quantity.
In an embodiment, the obtaining the second running number according to the first preset time and the third running time includes: detecting whether the accumulated running number is smaller than the second running number; and when the accumulated operation number is smaller than the second operation number, starting the first equipment. The second operation quantity is determined by the operation state parameter of the first device, that is, when the model of the first device is determined, the second operation quantity of the first device is fixed, and the accumulated operation quantity is a total value of accumulating the first device and the devices which are started to operate, that is, the accumulated operation quantity is changed along with the change of time, so that whether the first device exceeds the operation quantity upper limit of the device is determined by comparing the accumulated operation quantity with the second operation quantity. In this embodiment, when the accumulated operation number is smaller than the second operation number, the accumulated operation total number of the devices does not exceed the second operation number, so that the devices which are started before are not affected after the first devices are started, and the situation that the instantaneous current is too large when the devices work simultaneously is avoided.
In an embodiment, the detecting whether the accumulated operation number is smaller than the second operation number further includes: and when the accumulated operation number is greater than or equal to the second operation number, closing the first equipment. The accumulated operation quantity is the total quantity of the devices which are statistically operated, the second operation quantity is the upper limit of the operation quantity of the devices, and whether the quantity of the devices which are currently operated exceeds the upper limit is determined by comparing the accumulated operation quantity with the second operation quantity. In this embodiment, when the cumulative operating number is greater than or equal to the second operating number, that is, the total number of currently operating devices has reached the upper limit of the operable number of devices, turning on the first device again inevitably causes the first device to affect the operation of the previous device, that is, the peak load time of the first device may overlap with the peak load time of one of the previous devices, and in order to avoid the above situation, the first device is not turned on.
In an embodiment, the first operation number and the second operation number are used as preset operation numbers, and the first operation number and the second operation number are determined according to models of devices, and the first operation number and the second operation number are combined, so that the cumulative operation number is correspondingly increased, the operable number of the devices is further increased, and the number of the devices which operate simultaneously is increased. In this embodiment, the preset operation number is equal to the sum of the first operation number and the second operation number plus 1, that is, the preset operation number is 1 more than the sum of the first operation number and the second operation number.
In one embodiment, the turning on and operating the second device includes: starting the second device; and acquiring the running state parameters of the second equipment. After the second device is started, in order to facilitate the starting of the next device, the second device needs to be monitored in real time for the operation state parameters. In this embodiment, after the second device is turned on, the previous steps S100 to S300 are repeated, specifically, after the second device is turned on, the next device is used as a new second device, and the second device is used as a new first device, so that it is more convenient to control the turning on of the multiple devices, that is, only the turning on time of the next device needs to be determined according to the running state of the previous device, and the policy adjustment for controlling the next device after the number of devices changes is effectively avoided.
In an embodiment, the detecting whether the operation duration of the first device is greater than or equal to the first preset time further includes: and returning to the previous step when the running time of the first equipment is less than the first preset time. In this embodiment, when the operation duration of the first device is less than the first preset time, it indicates that the operation duration of the first device from the start-up to the present time is shorter than the first preset time, and since the first preset time is the time between the first occurrence of the peak load and the last occurrence of the peak load during the operation of the first device. In order to avoid the time period of the peak load of the second device from overlapping with the time period of the peak load of the first device, the second device is not turned on, and the operation time period of the first device is returned to step S200 to continuously compare the first preset time with the operation time period of the first device, so that the time period of the peak load of the second device is staggered with the time period of the peak load of the first device, thereby avoiding the situation that the surge current is too large in the operation process of the first device and the second device, and prolonging the service life of the devices.
The invention also provides an equipment operation control system, which comprises an acquisition module, a detection module and a control module; the acquisition module is used for acquiring first preset time of first equipment; the detection module is used for detecting whether the running time of the first equipment is greater than or equal to the first preset time or not; the control module is used for starting and operating second equipment when the operation duration of the first equipment is greater than or equal to the first preset time.
