referring to fig. 1, fig. 1 is a circuit breaker provided in an embodiment of the present application, and the circuit breaker includes a circuit breaker body, a sensor, and a first communication module. Wherein:
the sensor set up in on the circuit breaker body for gather the state information of circuit breaker body. And the first communication module is connected with the sensor and used for sending the state information acquired by the sensor to the external equipment.
The breaker is a switching device capable of closing, carrying, and opening a current under a normal circuit condition and closing, carrying, and opening a current under an abnormal circuit condition for a predetermined time. The circuit breaker can be used for distributing electric energy, protecting circuits and the like, and automatically cutting off the circuits when the circuits and the like have serious overload or faults such as short circuit, undervoltage and the like. The breaker body in the embodiment of the present application can be implemented using a conventional short breaker structure. Illustratively, the circuit breaker body may include a contact system, an arc extinguishing system, a conductive system, and the like.
It should be further noted that, in the embodiment of the present application, the sensor is used for collecting the operating state information of the circuit breaker. In practical applications, there are many factors that can affect the working condition of the circuit breaker, such as temperature, humidity, external force, deformation caused by external force, and the like. In the embodiment of the application, the state quantity required to be acquired can be determined according to actual needs, and different sensors are required to be used because the state quantities influenced by different factors are different. In the embodiment of the application, the acquisition of relevant state information can be realized through at least one of a temperature sensor, a humidity sensor, a voltage/current signal sensor, a force sensor and a deformation sensor, so that the state of the circuit breaker can be effectively acquired. It should be understood that the state information described in the embodiments of the present application refers to information that can represent an actual state of the circuit breaker body, and includes, but is not limited to, physical quantities such as temperature information, humidity information, and displacement condition of the circuit breaker body, and electric quantities such as current data and voltage data. Its totality, temperature sensor can be used for gathering the temperature information of circuit breaker body, and humidity transducer can be used for gathering the humidity information of circuit breaker body, and voltage/current signal sensor can be used for gathering the voltage or the current information of circuit breaker body, and force sensor then can be used for gathering the exogenic action size that the circuit breaker body received, and deformation sensor then can be used for gathering the deformation volume etc. of short circuiter body. In the embodiment of the present application, the sensor is disposed on the circuit breaker body, and the specific location of the sensor should be determined according to the type of the sensor and/or the actual arrangement environment, for example, for the force sensor, the force sensor may be arranged on the side of the circuit breaker body most susceptible to being squeezed by the external force according to the actual environment. Of course, where conditions permit, force sensors may be disposed at multiple locations on the circuit breaker body.
In the embodiment of the application, referring to fig. 2, the circuit breaker may further include an analog-to-digital converter, the sensor transmits the acquired state information to the analog-to-digital converter for data processing, and then the first communication module transmits the processed state information to the external device. It should be noted that, in the embodiment of the present application, the data processing performed by the analog-to-digital converter may include processing of converting the state information of the circuit breaker, collected by the sensor, from an analog signal to a digital signal, so that the transmitted state information is transmitted in the form of a digital signal, and compared with directly transmitting an analog signal, the communication security and the transmission reliability are enhanced. Meanwhile, the current access is usually digital equipment, so that the transmission by adopting digital signals is also convenient for processing by external equipment.
It is worth noting that the circuit breaker body is an electric appliance with contacts, and the purpose of opening and closing a circuit is achieved through opening and closing of the contacts in a contact system, so that corresponding operating mechanisms are needed to be arranged to achieve opening and closing control of the contacts in the contact system. As shown in fig. 3, in the embodiment of the present application, a corresponding operating mechanism may be disposed outside the circuit breaker body, and the operating mechanism may control the circuit breaker body to open when the first communication module receives an opening instruction, and control the circuit breaker body to close when the first communication module receives a closing instruction.
It should be noted that, in the existing circuit breaker, there is also a corresponding operating mechanism to implement the switching operation of the contact system. The operating mechanism that adopts in this application embodiment can adopt the operating mechanism among the current circuit breaker, and its difference lies in that current operating mechanism's control chip only can control operating mechanism and open a brake or close a floodgate operation by oneself when circuit etc. takes place serious overload or short circuit and trouble such as undervoltage, or corresponding control button is triggered. In the embodiment of the application, the first communication module can receive the opening instruction and the closing instruction, the control chip can control the operating mechanism to open the circuit breaker body when the first communication module receives the opening instruction, and can control the operating mechanism to close the circuit breaker body when the first communication module receives the closing instruction.

After the state information of the circuit breaker is acquired, the external equipment can be displayed to relevant users through various channels, or the state of the circuit breaker can be automatically analyzed based on the state information of the circuit breaker, so that the circuit breaker can be controlled and managed.
In a feasible implementation manner of the embodiment of the application, the arranged sensors simultaneously include a temperature sensor, a humidity sensor, a voltage/current signal sensor, a force sensor and a deformation sensor, so that the heat, the temperature, the humidity, the current data, the voltage data, the switching-on and switching-off times (which can be determined according to the disappearance times of the current/voltage collected by the voltage/current signal sensor, namely switching-off once when disappearing, and then reappearing once after disappearing, namely switching-on once), the magnitude of the external force, the vibration condition, the displacement condition (the displacement condition can be collected by the deformation sensor or by the displacement sensor) and other data of the sensors can be collected, and based on the data, external equipment can analyze and determine whether the breaker body has a fault or has a fault risk, and can roughly determine which type of fault exists or may exist, thereby facilitating maintenance by maintenance personnel. For example, if the temperature of gathering the circuit breaker body is greater than preset warning temperature, then can think that the circuit breaker has the risk of burning out or catching fire to can indicate maintainer to go to the cooling, and control circuit breaker stop work. For another example, if the collected current of the breaker body is higher than the preset warning current, it can be considered that the breaker circuit has a fault, and the maintenance personnel can be notified to go to the troubleshooting and control the breaker to stop working.
It should be noted that the two examples in the above paragraph are only two possible control and management schemes exemplified in the embodiments of the present application, and in practical applications, specific control and management schemes may be set according to actual needs, and are not enumerated in the present application.

In the embodiment of the application, the circuit breaker and the smart meter can be jointly arranged in a power supply line of a user as a part of a user power utilization system. In order to realize communication between the circuit breaker and the smart meter, in this embodiment of the present application, the first communication module and the second communication module may be connected in a wired or wireless manner, but considering that the wired connection has a higher requirement for the layout environment of the circuit breaker and the smart meter, in a feasible implementation manner of this embodiment of the present application, the first communication module and the second communication module may be adapted wireless communication modules, for example, may be WIFI modules, and the like, so as to reduce the requirement for the layout environment of the circuit breaker and the smart meter, and enable this embodiment of the present application to be applied to more and more complex actual scenes.

It should be understood that, a plurality of smart electric meters can be connected to the data platform in this application, and the data platform can mark to each smart electric meter to obtain which smart electric meters belong to same building, or belong to same district, or belong to same street etc. and then can synthesize the arrangement to the data that belong to same building, or belong to same district, or belong to the smart electric meter on same street, obtain and belong to same building, or belong to same district, or belong to the relevant power consumption condition on same street. For example, data transmitted by all smart meters belonging to the same building can be integrated to obtain information such as voltage and current fluctuation of each building in the last 24 months, load alarm times and the like. For another example, according to the analysis of the electricity consumption information transmitted by the smart meter, aiming at the smart meter with the arrearage condition, the breaker corresponding to the smart meter can be remotely controlled to be opened through the transmission path of the data platform, the smart meter, the second communication module and the first communication module, so as to cut off the power supply; when the intelligent electric meter transmits data that the defaulting condition disappears, the breaker corresponding to the intelligent electric meter is remotely controlled to be switched on through the same transmission path so as to recover power supply. In addition, the data platform can also determine whether the breaker fails according to the breaker state information transmitted by the intelligent electric meter. For example, if the collected voltage of the circuit breaker is higher than a preset warning voltage, it can be considered that a fault exists in the circuit of the circuit breaker.
