Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, 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 invention.
In order to realize the optimization of the operation of the electric heating equipment within the allowable range of safe power, the embodiment of the invention provides a method, a device and a system for controlling the electric heating equipment.
As shown in fig. 1, an architecture diagram of an electric heating equipment control device according to an embodiment of the present invention includes: the electric heating system comprises an electric heating equipment distributor and a plurality of electric equipment, wherein the plurality of electric equipment at least comprise one electric heating equipment controlled by a temperature controller.
In an actual application scenario, the plurality of electric devices may be all electric heating devices, or may include both electric heating devices and other electric devices. The scheme of the invention aims to control the electric heating equipment in the system to avoid current overload when the power consumption is overloaded without influencing the normal use of other power consumption equipment.
There may be one or more consumers in the system and there may be one or more electric heating devices. As shown in fig. 1, the electric heating equipment in the system is controlled by a temperature controller and is connected to an electric heating equipment distributor through the temperature controller, and the electric heating equipment distributor is connected with a bus; and the other electric equipment can be electric equipment controlled by the temperature controller or electric equipment not controlled by the temperature controller, correspondingly, the other electric equipment controlled by the temperature controller is connected to the bus through the temperature controller, and the other electric equipment not controlled by the temperature controller is directly connected with the bus. In addition, one temperature controller may correspond to one electric heating device, or may correspond to a plurality of electric heating devices, which is not limited in the present invention.
In one implementation, the electric heating device distributor, the temperature controllers, and the electric heating device can all be connected by buses, such as RS485 and RS 232.
It should be noted that the temperature controller in the system may control the temperature of one electric device or may control a plurality of electric devices, and the embodiment of the present invention does not limit the number of electric devices controlled by the temperature controller.
In the system, an electric heating equipment distributor acquires bus current in real time; if the bus current is greater than or equal to the preset total rated current and the electric heating equipment exists in the electric equipment, selecting equipment to be closed from the electric heating equipment; and closing the equipment to be closed.
In the prior art, current overload cannot be observed, so that a user cannot avoid the occurrence of overload. It can be understood that when the bus current in the circuit is greater than or equal to the total rated current, the circuit is easy to generate current overload, which indicates that the circuit has the risk of current overload, and when the bus current is less than the total rated current, the current overload phenomenon does not occur, namely, the circuit does not have the risk of current overload, therefore, the scheme of the invention controls the electric heating equipment in the system by monitoring the magnitude relation between the bus current and the total rated current, and can achieve the purpose of optimizing the operation of the electric heating equipment.
When the system provided by the embodiment of the invention controls the electric heating equipment, the distributor of the electric heating equipment acquires the bus current in real time, and when the bus current exceeds the preset total rated current and the current overload condition is easy to occur, the electric heating equipment in the running state is selected from the electric equipment to be used as the equipment to be closed and is closed, so that the size of the bus current in the circuit is reduced, the bus current is smaller than the total rated current, and the current overload is avoided. Therefore, the optimization of the operation of the electric heating equipment is realized within the allowable range of safe power.
In a preferred scheme, after the distributor of the electric heating equipment closes the electric heating equipment, the distributor marks the electric heating equipment as a limited operation state and starts to time the electric heating equipment; if the bus current is less than the total rated current, selecting equipment to be started from the electric heating equipment which is in the limited operation state and the timing is finished; and opening the device to be opened.
Specifically, after the electric heating equipment is marked in the operation limiting state, the electric heating equipment can be timed in a countdown mode or a positive timing mode. It should be noted that the countdown method and the count-up method are only two specific methods for timing the operation state of the electric heating device, and the present invention is not limited thereto.
In the case of an electric heating equipment control system, the purpose of protecting the electric circuit is only to avoid overload of the electric circuit, and in addition, when the bus current in the electric circuit is less than the total rated current, the electric heating equipment in the limited operation state needs to be recovered to operate.
In the scheme, the electric heating equipment with limited operation is timed, and the electric heating equipment is started only when the timing is completed and the circuit meets the current relation that the bus current is less than the total rated current. That is, once the electric heating apparatus is marked in the limited operation state, it is turned on again at least after waiting for the set timer time. Therefore, the situation that the electric heating equipment is repeatedly opened or closed due to the change of the current relation between the bus current and the total rated current is avoided, and the service life of the electric heating equipment is favorably protected.
Correspondingly, an embodiment of the present invention provides a method for controlling an electric heating device, as shown in fig. 2, which is a flowchart of the method for controlling an electric heating device provided in the embodiment of the present invention, and the method includes the following steps:
s101: the bus current is acquired in real time.
It is understood that the bus current is a trunk current in the circuit, and for a circuit, the trunk current is equal to the sum of the branch currents, i.e., the sum of the branch currents flowing through the respective electrical devices in the operating state.
S102: and judging whether the bus current is larger than or equal to a preset total rated current, and if so, executing the step S103.
In one implementation, the rated current of the air circuit breaker connected to the bus may be set to a total rated current. The present invention is not limited to the setting method of the total rated current.
It can be understood that when the bus current in the circuit is greater than or equal to the total rated current, the circuit is easy to generate current overload, and when the bus current is less than the total rated current, the current overload phenomenon can not occur, therefore, the scheme of the invention controls the electric heating equipment in the system by monitoring the magnitude relation between the bus current and the total rated current, and can achieve the purpose of optimizing the operation of the electric heating equipment.
S103: and if the electric equipment comprises electric heating equipment, selecting equipment to be shut down from the electric heating equipment.
For different types of electric equipment, the power of the electric heating equipment is usually larger, so when the bus current in the circuit is larger than or equal to the total rated current, the circuit is always at risk of current overload, and therefore the electric heating equipment with the larger power in the electric equipment is selected to be turned off.
It should be noted that the present invention is intended to control the electric heating devices in the system, and therefore, the situation that the electric heating devices are not present in the electric devices is not within the protection scope of the embodiment of the present invention.
S104: and closing the equipment to be closed.
When the method provided by the embodiment of the invention is applied to control the electric heating equipment, the bus current can be obtained in real time, and when the bus current exceeds the preset total rated current and the current overload condition is easy to occur, the electric heating equipment in the running state is selected from the electric equipment to be used as the equipment to be closed and is closed, so that the size of the bus current in the circuit is reduced, the bus current is smaller than the total rated current, and the current overload is avoided.
As shown in fig. 3, which is a flowchart of another method for controlling electric heating equipment according to an embodiment of the present invention, the method according to the embodiment of the present invention is different from the method according to the embodiment of fig. 2 in that the method according to the embodiment of fig. 3 may further include the following steps:
s105: the method comprises the steps of acquiring the ambient temperature and the set temperature corresponding to each electric heating device in real time, and calculating the temperature difference between the set temperature and the ambient temperature.
In practical application, when the ambient temperature is close to the set temperature, even if the electric heating equipment in the limited operation state has the condition of being turned on again, the electric heating equipment does not need to be turned on again in order to save electric energy. Therefore, the preferred embodiment shown in fig. 3 further considers the relationship between the ambient temperature and the set temperature corresponding to the electric heating equipment.
In the electric heating device control system shown in fig. 3, the ambient temperature of the electric heating device can be obtained in real time by using the temperature acquisition function of the temperature controller. Of course, the invention does not limit the manner of obtaining the ambient temperature of the electric heating equipment.
S1031: and if the electric heating equipment exists in the electric heating equipment, taking the N electric heating equipment corresponding to the minimum temperature difference in the electric heating equipment as equipment to be closed, wherein N is more than or equal to 1.
It can be understood that the smaller the temperature difference between the set temperature and the ambient temperature is, the closer the ambient temperature of the electric heating equipment is to the set temperature, and the heating requirement on the electric heating equipment is lower at this time; the larger the temperature difference between the set temperature and the ambient temperature is, the farther the ambient temperature of the electric heating equipment is from the set temperature, and the higher the heating demand on the electric heating equipment is. Therefore, when there are a plurality of electric heating devices in an operating state in the electric heating device control system, in order to ensure the heating requirement of the user, the electric heating devices with higher heating requirement are often required to be reserved, and the electric heating devices with lower heating requirement are turned off.
When the method provided by the embodiment shown in fig. 3 is used for controlling the electric heating equipment, in addition to all the advantages of the embodiment shown in fig. 2, the heating condition of the electric heating equipment to the ambient temperature is also considered, and when the bus current is greater than or equal to the total rated current, especially when a plurality of electric heating equipment in the running state exist at the same time, the electric heating equipment with lower heating requirement can be preferentially selected to be closed, so that the heating requirement of a user can be better ensured while the current overload is avoided.
As shown in fig. 4, which is a flowchart of another method for controlling electric heating equipment according to an embodiment of the present invention, the method according to the embodiment of the present invention is different from the method according to fig. 3 in that the method according to the embodiment of fig. 4 may further include the following steps:
s106: after the electric heating equipment is turned off, the electric heating equipment is marked as a limited operation state, and the electric heating equipment is timed.
It can be understood that the on and off of the electric devices in the electric heating control system are variable at any time, accordingly, the bus current is also in dynamic change, and the current relationship between the bus current and the total rated current is also changed. In the solution of the present invention, the device to be shut down is selected to avoid the circuit from being overloaded, but when the bus current in the circuit is less than the total rated current, the function of the electrical equipment in the limited operation state, such as the electrical heating equipment, needs to be available, even if the electrical equipment is in the operation state again.
Specifically, after the electric heating equipment is marked in the operation limiting state, the electric heating equipment can be timed in a countdown mode or a positive timing mode. It should be noted that the countdown method and the count-up method are only two specific methods for timing the operation state of the electric heating device, and the present invention is not limited thereto.
In the scheme, the electric heating equipment with limited operation is timed, and the electric heating equipment is started only when the timing is completed and the circuit meets the current relation that the bus current is less than the total rated current. That is, once the electric heating apparatus is marked in the limited operation state, it is turned on again at least after waiting for the set timer time. Therefore, the situation that the electric heating equipment is repeatedly opened or closed due to the change of the current relation between the bus current and the total rated current is avoided, and the service life of the electric heating equipment is favorably protected.
In one implementation, the value of the timing time may be set according to the number of the electric devices in the electric heating control system, or may be set according to the power of the electric heating devices. It should be noted that the embodiment of the present invention does not limit the time value of the timing, and a person skilled in the art may set the time value according to the specific situation in the practical application.
S107: and if the bus current is less than the total rated current, selecting equipment to be started from the electric heating equipment which is in the limited operation state and the timing is finished.
S108: and opening the equipment to be opened.
When the method provided by the embodiment shown in fig. 4 is used for controlling the electric heating equipment, except for all advantages of the embodiment of the method shown in fig. 3, the method automatically selects the electric heating equipment in a limited operation state to start under the condition that the bus current is less than the total rated current, namely, the current overload risk is not existed, manual starting is not needed, the heating requirement of a user is better met, and the operation of the electric heating equipment is further optimized; in addition, the closed equipment to be closed is marked as the operation limiting state, and the electric heating equipment with operation limiting is timed, so that the electric heating equipment with operation limiting can be restarted after the timing of the electric heating equipment with operation limiting is finished and the bus current is less than the total rated current, the situation that the electric heating equipment is repeatedly started or closed is avoided, and the service life of the electric heating equipment is favorably protected.
As shown in fig. 5, which is a flowchart of another method for controlling electric heating equipment according to an embodiment of the present invention, the method according to the embodiment of the present invention is different from the method according to fig. 4 in that the equipment to be turned on may be selected as follows:
s1071: and taking M electric heating devices corresponding to the maximum temperature difference in the electric heating devices with limited operation states and completed timing as devices to be started, wherein M is more than or equal to 1.
Referring to the description of the embodiment of the method shown in fig. 3, the smaller the temperature difference between the set temperature and the ambient temperature, the closer the ambient temperature of the electric heating equipment is to the set temperature, and the lower the heating demand on the electric heating equipment is; the larger the temperature difference between the set temperature and the ambient temperature is, the farther the ambient temperature of the electric heating equipment is from the set temperature, and the higher the heating demand on the electric heating equipment is. Therefore, when a plurality of electric heating devices meeting the re-opening condition exist in the electric heating device control system, the electric heating devices with higher heating requirements are often preferentially opened in order to guarantee the heating requirements of users.
When the method provided by the embodiment shown in fig. 5 is used for controlling the electric heating equipment, in addition to all the advantages of the embodiment shown in fig. 4, the heating condition of the electric heating equipment to the ambient temperature is also considered, and when the bus current is less than the total rated current, especially when a plurality of electric heating equipment meeting the re-opening condition exist at the same time, the electric heating equipment with higher heating requirement can be preferentially selected to be opened, so that the heating requirement of a user can be better ensured while the current overload is avoided.
