Detailed Description
The present invention will be described in further detail with reference to examples and drawings, but the embodiments of the present invention are not limited thereto.
As shown in fig. 1, the intelligent circuit breaker control method mainly comprises the following steps:
s100, establishing and storing association relations between each piece of load information and monitoring parameter information;
s200, acquiring load information based on user input and/or automatic identification, and retrieving corresponding monitoring parameter information based on association relation;
s300, acquiring corresponding monitoring parameter values based on the acquired monitoring parameter information;
and S400, comparing the monitoring parameter value with a corresponding fault threshold value, and controlling the opening and closing of the circuit breaker according to a comparison result.
In the above step S100, the load information specifically includes load ID information for distinguishing it from other load devices, including, but not limited to, the number, name, electricity usage characteristic information, or a combination thereof of the load devices, such as a three-phase motor, a home appliance IV, and the like. The monitoring parameter information includes names and characteristic data of various circuit parameters related to the load, including but not limited to: three-phase voltage, line voltage, current, temperature, line temperature, active power, power factor, etc. Different load devices correspond to different monitoring parameters, for example, when the three-phase motor operates, the phase of the power supply needs to be monitored compared with that of the single-phase motor.
In the step S100, the association relationship includes a correspondence relationship between the load information and each monitoring parameter information, and one load information may correspond to a plurality of monitoring parameter information, and similarly, the same monitoring parameter information may correspond to different load information.
In practical applications, the operation of the circuit breaker is controlled based on the collected relevant monitoring parameters, and usually, the operation state of a load device relevant circuit system needs to be characterized by a plurality of parameters, for example, the line voltage between three phase lines needs to be considered besides the current, the voltage and the phase when the three phase motor is driven, and in particular cases, the electromagnetic field, the temperature and other factors in the environment when the load device is operated need to be considered. The additional consideration is that the monitoring parameters only need to be collected in a specific scene, for example, when the ambient temperature is higher than the set value, the influence of the ambient temperature on the linear temperature needs to be considered. For this reason, in the embodiment of the present application, step S100 further includes:
s110, the monitoring parameter information associated with the load information is stored in an associated mode;
s111, establishing and storing rules for combining the monitoring parameter information associated with the same load information and generating triggering conditions corresponding to the parameter combinations;
and S112, detecting a trigger condition and establishing a matching corresponding relation between the load information and specific monitoring parameter information and/or monitoring parameter combination according to a detection result.
In the step S110, all the monitoring parameter information related to the load information is stored in association, and then in the step S111, a calling or combining rule of the monitoring parameter is established and a corresponding trigger condition is set, that is, a load device corresponds to a plurality of different monitoring parameter combining modes, and as mentioned above, according to the operation environment of the load device, the monitoring parameter of the environmental temperature is included in the parameter acquisition range to be used as one of references for controlling the circuit breaker. Finally, in step S112, a piece of load information corresponds to a plurality of monitoring parameters or combinations thereof, and the optimal monitoring parameter combination can be selected according to the detected actual use situation, so that the control of the circuit breaker is more accurate. As can be seen from the above method steps, in the embodiment of the present application, the matching correspondence between the load information and the monitoring parameter information is changed according to the actual use condition, so that the intelligent circuit breaker device can be adapted to different circuit systems, and different use conditions adopt different monitoring parameters or combinations thereof as the judging conditions for the circuit breaker to be opened.
After the association relationship between each item of load information and the monitoring parameter information is established, in step S200, the system may acquire the load information based on user input and/or automatic identification, and then call the corresponding monitoring parameter information based on the association relationship. For the user to input the load information, only relevant man-machine interaction components such as a touch screen, keys and the like are required to be configured between the control system and the user. In the embodiment of the application, the method further comprises automatic identification of the load equipment, such as automatic judgment of the type of the electric appliance after the circuit breaker is electrified, and if the three-phase power is found to be adopted, the open-end protection function is started, namely, the three-phase power phase and the voltage are monitored. The power utilization characteristics of different load devices after being electrified are different, and corresponding load information can be identified by utilizing the power utilization characteristics in the embodiment of the application, and the power utilization characteristic information of the load devices is only required to be stored in a correlated mode in the load information.
In the embodiment of the application, the load information and the corresponding monitoring parameter information are stored in an associated mode, and then when the intelligent circuit breaker device is expected to be connected between the load equipment and a power supply, a user only needs to input the load information such as a load name and the like, the control system can automatically match the associated monitoring parameter information, and corresponding circuit parameters such as voltage, current, temperature and the like of a wire are acquired based on the monitoring parameter information, so that the risk of manual misoperation can be effectively reduced.
In the embodiment of the application, the fault threshold is configured to be set by user input, or is directly loaded in load information and extracted from the load information, or is automatically generated according to a monitoring parameter value corresponding to specific monitoring parameter information and a setting algorithm. Preferably, the method can be implemented in a manner of loading the power supply directly in the load information, such as loading the rated power value of the power supply in the lighting load information.
Preferably, the method for setting or automatically generating the fault threshold in the embodiment of the present application, as shown in fig. 2, includes:
s410, according to the correlation between the monitoring parameter information and the load safety operation state, classifying the monitoring parameter information corresponding to the same load information into a core monitoring parameter and an auxiliary monitoring parameter, wherein when the load equipment is a three-phase motor, the phase parameter is the core monitoring parameter, the line temperature of each phase of power supply wire is the auxiliary monitoring parameter, once the former is abnormal, the load damage or the work abnormality can be directly caused, and the latter is a potential characterization phenomenon that a certain fault is about to happen.
S411, setting a safe interval range of the core monitoring parameter and taking an interval endpoint value as a first fault threshold value;
s412, setting and storing a functional formula for representing the relation between the core monitoring parameters and the auxiliary monitoring parameters;
s413, collecting the core monitoring parameter value in the circuit system, substituting the core monitoring parameter value into the functional formula, and calculating to generate a second fault threshold value for judging whether the auxiliary monitoring parameter is abnormal.
According to the technical scheme, the monitoring parameter directly related to the safe operation of the load equipment can be used as the core monitoring parameter, and when the actually collected related monitoring parameter value exceeds the first fault threshold value, the circuit breaker is controlled to be turned off, so that the load equipment is protected; the second fault threshold corresponding to the auxiliary monitoring parameter fluctuates within a certain interval according to the change of the core monitoring parameter, i.e. the second fault threshold is a variable. The above-mentioned setting can make the response of intelligent circuit breaker 7 more accurate to based on the dual check of core monitoring parameter and supplementary monitoring parameter, when a certain settlement monitoring parameter value takes place unusually but not gathered by the sensor, can reflect above-mentioned trouble or abnormal existence through the check of other monitoring parameter values, promote the reliability of control system to circuit system fault judgement.
In practical applications, there is a correlation between the monitored parameters corresponding to the load device, for example, the temperature is often correlated with the current, and the phase sequence between the three phases of electricity is also correlated. In step S100 of the present application, the method further includes the following sub-steps:
s120, acquiring a plurality of pieces of monitoring parameter information corresponding to the same load information based on the association relation between the stored load information and the monitoring parameter information;
s121, analyzing and generating or directly obtaining the association relation between the monitoring parameter information, and fitting and generating a plurality of verification functions, wherein the association relation between the temperature and the current intensity is represented by the verification functions.
Based on the above settings, the intelligent breaker 7 control method of the present application further includes:
s500, substituting the collected monitoring parameter values into the check functions respectively, judging whether a specific monitoring parameter value or a monitoring parameter value combination is generated to be in a normal interval, and outputting alarm information according to a judging result.
According to the technical scheme, a plurality of checking functions for checking whether a certain monitoring parameter is normal or not are generated based on the relevance among the monitoring parameters, the collected actual monitoring parameter values are input into the checking functions, and when one or more monitoring parameters do not meet the checking functions, alarm information is output. Because the values of the monitoring parameters do not exceed the fault threshold, the change of the association relation among the monitoring parameters does not represent the fault of the circuit system, and therefore, the output alarm information reminds a user to check the related monitoring parameters, the occurrence probability of the fault is reduced, and the control system has the function of pre-judging the occurrence of the fault. The alarm information can be transmitted to a specific monitoring terminal, such as a monitoring platform or a smart phone corresponding to maintenance personnel, through a corresponding data communication unit.
In the actual operation of the load device, various monitoring parameter values are affected by various factors such as ambient temperature and electromagnetic radiation, wherein some monitoring parameters, such as the line temperature of the three-phase line, can generate small-range fluctuation along with the change of the ambient temperature, the temperature fluctuation is not caused by the current or voltage change in the power supply cable, and the change of the monitoring parameter values can occur on other loads of the same type in the same area or circuit system. For this reason, based on the current mature internet of things technology, the intelligent circuit breaker 7 control method of the present application further includes:
s420, establishing monitoring parameter data connection between independent loads of the same type in the same circuit system;
s421, acquiring each load and each corresponding monitoring parameter value thereof, and generating each monitoring parameter change curve;
s422, analyzing parameter change curves corresponding to the same type of monitoring parameters in each load, determining the planned system variable and the mutation amount in the monitoring parameter values, for example, if the corresponding monitoring temperature values in each independent load are increased in a small amplitude, the change of the monitoring parameter values can be defined as the planned system variable, and if only the temperature of a certain load device is increased, the planned system variable and the mutation amount can be determined.
S423, adjusting the corresponding fault threshold value of the relevant monitoring parameters according to the proposed system variables, for example, adjusting the corresponding temperature threshold value in the monitoring parameters to be higher in a high-temperature environment so as to eliminate the influence of the environmental temperature on the monitoring result. According to the technical scheme, related interference can be eliminated when system fault judgment is carried out, misjudgment is reduced, and meanwhile, the fault threshold corresponding to the related monitoring parameters can be adjusted according to the change of external influence factors, so that the fault judgment is more accurate.
In this embodiment, as shown in fig. 3, the control method of the intelligent breaker 7 further includes the steps of energy saving and protection of the load:
s610, establishing control connection and data communication connection between the circuit breaker and an external monitoring platform;
s611, establishing and storing monitoring parameters used for representing that the load corresponding to each load information is in a normal working state or a standby state;
