The embodiments of the present invention will be described in further detail with reference to the drawings attached hereto.
Referring to fig. 1, an embodiment of the invention provides a multi-load startup control method, and a main flow of the method is described as follows.
As shown in fig. 1:
step 1000: acquiring current behavior information of a current user; the behavior information includes load start information.
Wherein, the current user refers to a user who wants to start the load; when a plurality of users start a single load or a plurality of loads simultaneously and a single user starts a plurality of loads simultaneously, corresponding load starting information is formed; the current behavior information can be acquired by a mechanical key triggering mode or a virtual key triggering mode; the mechanical key triggering mode can start the related load by pressing the start key, so as to obtain the corresponding current behavior information; the virtual key triggering mode can realize starting of the related load by pressing the related virtual triggering key in the interface of the corresponding software, so as to obtain the corresponding current behavior information.
Step 2000: and judging whether at least two pieces of load starting information are acquired or not according to all the acquired load starting information.
Step 3000: and if at least two pieces of load starting information are acquired, current starting trigger information is formed.
And forming corresponding starting trigger information according to the load starting information, wherein the starting trigger information corresponds to the condition that a plurality of loads are started simultaneously.
Step 4000: searching current instruction information corresponding to the current starting trigger information from a preset corresponding relation between the starting trigger information and the instruction information; the instruction information includes start execution information corresponding to the start trigger information.
After the current starting trigger information is acquired, inquiring between the preset starting trigger information and the instruction information, and after the instruction information corresponding to the current starting trigger information is inquired, the inquired instruction information is the starting execution information.
Step 5000: and forming a starting priority for the loads which need to be started at the same time according to the current starting execution information, and sequentially spacing preset interval periods according to the starting priority to start the related loads.
The judgment method of the load needing to be started at the same time comprises the following steps:
searching corresponding starting execution information to form starting priority for related loads needing to be started at the same time, and then sequentially starting the loads; as shown in fig. 2, the method for determining the loads required to be started at the same time is as follows:
step 5110: and acquiring time nodes corresponding to the related formed load starting information.
Step 5120: and taking the time node corresponding to the first formed load starting information as an initial time node, and judging whether the time nodes corresponding to the rest load starting information are in a preset time period or not according to the initial time node.
Step 5130: if the load is in the preset time period, the load belongs to the load started at the same time.
Step 5140: if the load is not in the preset time period, the load does not belong to the load started at the same time.
The time period in this embodiment may be any number between 1-100 microseconds, and this embodiment preferably uses 10 microseconds; because only the load started at the same time can affect the power supply, the influence of the gradually added load on the power supply is relatively small, and the load can be ensured to be started, whether the load started at the same time needs to be judged, namely, when the judgment needs to have a starting point, the first time node for accessing the load is taken as the starting time node; and defining all started loads from the time node of the first access load to a preset time period as the loads started at the same time.
Regarding the method of initiating the priority formation:
the starting priority may be formed in various ways, and the corresponding priority may be randomly generated, formed according to a preset sequence, or read by a corresponding number to form the corresponding priority.
In one embodiment, as shown in FIG. 3, loads that require the same time to start are based on a random algorithm to form a start priority; forming a corresponding starting priority through a random algorithm; the stochastic algorithm may be any conventional stochastic algorithm such as a numerical ranking algorithm, a numerical probability algorithm, a Las Vegas algorithm (LasVegas), a Monte Carlo algorithm (MonteCarlo), a Sheward algorithm (Sherwood), and so on. In this embodiment, a numerical sorting algorithm is preferably adopted, and the method for randomly forming the start priority is as follows:
step 5210: and acquiring current voltage information and current frequency information when the current load is accessed.
The voltage value and the voltage frequency value corresponding to the current load are formed when the current load is connected, and two parameters are obtained so as to facilitate subsequent data processing.
Step 5220: and performing logical operation on the numerical value corresponding to the current voltage information and the numerical value corresponding to the current frequency information to form sequencing data information.
The logical operation may be an exclusive-or operation, an and operation, an addition, subtraction, multiplication, division, or other types of operation, or other existing operation manners may be adopted, which is not described herein, and only data processing needs to be completed, and the exclusive-or operation is preferably adopted in this embodiment.
Step 5230: and sequencing the loads needing to be started at the same time from large to small or from small to large according to the numerical values corresponding to the sequencing data information to form a starting priority.
In the process of not starting the load, the current load is the load with a large power and the actual condition of the load cannot be known, so that the corresponding priority is formed in a random mode, a sequence is ensured, and the function of starting the load one by one is realized conveniently according to the sequence.
In one embodiment, as shown in fig. 4, the nodes form a start priority according to the time of load start; the method for forming the starting priority is as follows:
step 5310: and acquiring time nodes corresponding to the related formed load starting information.
Step 5320: and forming corresponding starting priority according to the sequence of the time nodes corresponding to all the load starting information.
And recording corresponding time nodes at the moment of starting the load, so as to obtain the time nodes, and sequencing the time nodes according to the sequence of the time nodes, thereby forming corresponding starting priority.
As shown in fig. 5, the method for monitoring the voltage of the current power supply during the start-up of each load is as follows:
step 6100: and acquiring current voltage information of the current power supply, wherein the voltage information comprises voltage drop information.
In the process that the load is connected into the power supply, instantaneous voltage drop occurs, namely the voltage condition of the current power supply is detected, and corresponding voltage drop information is formed once the instantaneous voltage drop occurs.
Step 6200: and comparing the pressure drop value corresponding to the pressure drop information with the value corresponding to the preset pressure drop reference information.
Step 6300: if the pressure drop value corresponding to the pressure drop information is larger than or equal to the value corresponding to the pressure drop reference information; and stopping starting the load after the current load according to the starting priority.
The current voltage information of the current power supply is monitored, and once the voltage drop is too large, the situation that the current power supply cannot access more loads is shown, and if the voltage drop is too large, all the loads are possibly turned off.
The access of a common load is realized through a relay, the triode is required to be in a conducting state in the action and the holding process of the relay, the current required by the action of closing a contact of the relay is higher, and the current required by the holding process is lower than the current required by the action, but the current required by the action and the current required by the holding process are always kept the same in the existing control mode, so that more heat can be generated when the relay is in the holding state, the relay is easy to age, the service life of the relay is shortened, and the electric energy is wasted; as shown in fig. 6, the method for controlling the on/off of the electric control device is as follows:
step 7000: the action current is switched on according to the action current required by the current electric control device.
Among these, an electric control device is an electric appliance that generates a predetermined step change in a controlled amount in an electric output circuit when a change in an input amount (excitation amount) meets a predetermined requirement. It has an interactive relationship between a control system (also called an input loop) and a controlled system (also called an output loop). It is commonly used in automated control circuits, which are actually a "recloser" that uses low current to control high current operation. Therefore, the circuit plays the roles of automatic regulation, safety protection, circuit conversion and the like.
In this embodiment, the electric control device preferably used is a relay, and the action current of the relay is a current value that must be reached in the corresponding starting process of the current relay, otherwise, the magnetic force formed after the coil of the relay is turned on cannot complete the contact attracting function, so in the starting process, the corresponding action overcurrent needs to be accessed first to ensure that the contact of the relay can be closed, so that the power supply loop corresponding to the load is turned on.
Step 8000: keeping the action current for a preset action time period.
The action time period is the time interval from the moment of applying an input excitation specified value to the moment of switching the contact point of the relay in a release state in the action process of the relay under a specified condition; i.e. maintaining the corresponding time ensures that the present relay is in a closed state.
Step 9000: after the action time period passes, switching the accessed action current to a holding current required by the current electric control device; wherein the holding current is less than the operating current.
The current connected to the current control device is regulated in a relevant regulation and control mode, the current can be changed by connecting resistors with different resistance values at most basically, and the corresponding output current can be controlled by regulating the duty ratio.
In the present embodiment, it is preferable to adjust the duty ratio to adjust the current to be switched in, by adjusting the ratio of the on time and the off time of the power switch device to respond to the change of the input or output voltage. In this regard, common duty cycle control and current mode control are similar, both of which accomplish output regulation by adjusting the duty cycle. They differ in that the duty cycle can only be adjusted by conventional duty cycle control based on changes in the output voltage, whereas current mode control adjusts the duty cycle based on changes in the main (power) inductor current.
In the process of continuously accessing the load, the voltage is influenced, relevant pulse fluctuation is generated, the pulse fluctuation can cause correspondence, different pulse fluctuation corresponds to different states, the corresponding pulse fluctuation condition is distinguished according to the duration time of the pulse, and whether the corresponding holding current needs to be continuously accessed or not is analyzed according to the current condition so as to enable the current electric control device to be conducted; therefore, after the holding current required by the current electric control device is switched on, the voltage of the current power supply is monitored, as shown in fig. 7, the specific method is as follows:
step 9100: and acquiring current voltage information of the current power supply, wherein the voltage information comprises voltage pulse fluctuation information.
The current voltage information is a voltage value corresponding to the current power supply, and in the continuous detection process of the voltage value, if corresponding pulse fluctuation occurs, the pulse fluctuation is voltage pulse fluctuation information.
Step 9200: and judging whether the current voltage pulse fluctuation information appears.
In the process of continuously acquiring the current voltage information, judging whether the current voltage has corresponding pulse fluctuation or not, namely judging whether the current voltage pulse fluctuation information exists or not; when the corresponding current voltage pulse fluctuation information is acquired, the current voltage pulse fluctuation information can be stored in a corresponding database so as to be convenient for subsequent calling and analysis, and the current service life of the relay and some factors influencing the service life are judged.
Step 9300: and if the current voltage pulse fluctuation information exists, controlling whether to continuously access the holding current required by the current electric control device according to the duration of the current voltage pulse fluctuation information.
If the pulse fluctuation is less than the corresponding duration period, it is indicated that only some simple interferences are caused at the moment, namely voltage fluctuation generated in the process of accessing the load, so that the influence generated by the voltage fluctuation is avoided directly through related algorithm filtering, and if the pulse fluctuation is greater than the corresponding duration period, the power supply is dead at the moment, so that electric energy corresponding to so much load cannot be provided, and the current electric control device is directly turned off; the method for judging the duration of the current voltage pulse fluctuation information comprises the following steps:
step 9310: whether the duration of the current voltage pulse fluctuation information is longer than a preset duration period.
The corresponding voltage pulse fluctuation information has a duration, so that the duration corresponding to the current voltage pulse fluctuation information is judged, the duration period is preferably 100 microseconds-1 millisecond, and the duration period in the application can be a time value or a time range; in one embodiment, the duration period is a time value, and the time value can be any number between 100 microseconds and 1 millisecond, and 100 microseconds is preferably adopted in the application, namely the duration of the current voltage pulse fluctuation information is compared with 100 microseconds; in one embodiment, the duration period is a time range, the time range is 100 microseconds to 1 millisecond, and the duration of the current voltage pulse fluctuation information is preferably compared with 100 microseconds and 1 millisecond in the present application, that is, whether the duration of the current voltage pulse fluctuation information is less than 100 microseconds or not and whether the duration of the current voltage pulse fluctuation information is more than 1 millisecond or not are judged. In the examples of the application, a mode in which the duration period is one time range is preferably employed.
Step 9320: and if the duration of the current voltage pulse fluctuation information is less than the duration period, continuing to switch in the holding current required by the current electric control device.
And judging whether the duration of the current voltage pulse fluctuation information is less than 100 microseconds or not, if so, judging that the duration is less than 100 microseconds, and only the interference is carried out at the moment but not the situation that the power supply is not powered off, so that the holding current required by the current electric control device is continuously accessed. In addition, the method for continuing to switch on the holding current required by the current electric control device is as follows:
step 9321: and comparing the voltage value corresponding to the current voltage pulse fluctuation information with a preset fluctuation reference value.
Step 9322: if the voltage value corresponding to the current voltage pulse fluctuation information is smaller than the preset fluctuation reference value; and adjusting the current value corresponding to the current voltage pulse fluctuation information to a current value corresponding to a fluctuation reference value by adjusting the duty ratio of the PWM, and keeping the current value corresponding to the fluctuation reference value.
The preset fluctuation reference value is any number between 4V and 8V, and is preferably 5V in the embodiment; in the process of continuing to access the holding current, the current voltage pulse fluctuation information is detected, once the voltage value corresponding to the current voltage pulse fluctuation information is smaller than a preset fluctuation reference value, the interference influence on the current voltage pulse fluctuation information is larger, and in order to avoid the condition that the current electric control device is tripped, the duty ratio of PWM is regulated and controlled so that the current value can be stabilized at the current value corresponding to the fluctuation reference value, and the service life of the current electric control device is prevented from being influenced after the current electric control device is sent for multiple times of tripping.
Step 9330: if the duration of the current voltage pulse fluctuation information is longer than the duration period, stopping accessing the holding current required by the current electric control device to switch off the current electric control device; and sending corresponding feedback information to the current user.
If the pulse fluctuation is greater than the corresponding duration period, the power supply is dead, so that the electric energy corresponding to the load cannot be provided, and the current electric control device is directly turned off; after the power is turned off, information feedback is carried out on the current user to remind the current user of power replacement or maintenance, and the feedback information comprises sound feedback information and/or lamplight feedback information and/or short message feedback information and/or pop-up window feedback information; the feedback information can be realized in various forms, and can be adjusted according to actual conditions by adopting the combination of one or more feedback information; after the current electric control device is turned off, the specific method for detecting the current voltage information is as follows:
step 9331: and comparing the voltage value corresponding to the current voltage information with the preset voltage reference value.
Step 9332: and if the voltage value corresponding to the current voltage information is larger than the preset voltage reference value, switching in the action current according to the action current required by the current electric control device, and switching the accessed action current to the holding current required by the current electric control device after the action time period.
The preset voltage reference value is any number between 4V and 8V, and is preferably 5V in the embodiment; and continuing to monitor the current voltage information after the current voltage information is turned off, and once the voltage value corresponding to the current voltage information is larger than the preset voltage reference value, indicating that the current power supply can continue to supply power, so that the action current is switched in again, and the action current is switched to the holding current after an action time period, so that the processes of starting and keeping on of the current electric control device are completed.
If the pulse fluctuation is larger than the corresponding duration period, the voltage is reduced due to excessive load, and the power supply of excessive load cannot be borne; so during the process of stopping the holding current required by the present electric control device to turn off the present electric control device, it is possible to try to disconnect some of the loads in such a way that the power supply can supply power to the remaining loads, as follows:
step 9341: acquiring current rated power information corresponding to current equipment;
step 9342: forming a priority according to the numerical value of the current rated power information corresponding to the current equipment from big to small;
