Detailed Description
The technical solution of the present application is further described in detail below with reference to the accompanying drawings.
The low-voltage circuit breaker comprises a release, a hoe system, an arc extinguishing device, a transmission mechanism, a base frame, a shell and the like, and in the application, please refer to fig. 1, for convenience of understanding and description, the low-voltage circuit breaker is simplified into a main body 11 and a control panel 12, the main body 11 is provided with an input end and an output end, the input end of the main body 11 is electrically connected with a municipal administration, and the output end is electrically connected with a circuit in a charging pile.
Referring to fig. 2, the closing and opening of the main body 11 can be realized by providing a plurality of sets of moving contacts and static contacts on the main body 11, wherein the moving contacts and the static contacts are separated when the low-voltage circuit breaker is in an open (power-off) state, and the moving contacts and the static contacts are in contact when the low-voltage circuit breaker is in a closed (power-on) state.
The action of the moving contact can be realized through the electromagnet, the control end of the electromagnet is connected with the control panel 12, the control panel 12 drives the moving contact to act by controlling the on-off of the electromagnet, and then the on-off control of the main body 11 is realized.
The signal receiver 13 is mounted on the control board 12 or integrated into the control board 12. The signal receiver 13 is used for detecting whether the paired signal source is in the range, so as to determine whether the bound electric vehicle moves into the specified range, as shown in fig. 3.
When the electric vehicle bound with the signal receiver 13 moves to a specified range, the signal receiver 13 receives a signal sent by the paired signal source. The signal receiver 13 closes the main body 11 through the control board 12; when the bound electric vehicle leaves the designated range, the signal receiver 13 cannot receive the signal sent by the paired signal source, and the signal receiver 13 disconnects the main body 11 through the control board 12.
The designated range refers to an operating range of the signal receiver 13, for example, an effective operating distance of the signal receiver 13 is 5 meters, when the paired signal source moves to the operating range, the main body 11 will be turned from the open state to the closed state, and vice versa.
For the source of the paired signal source, there are several forms:
1. the electric automobile is provided with a signal transmitter, the electric automobile can send out a signal with a unique identity mark, and the signal receiver 13 recognizes the signal as a judgment basis;
2. an independent signal transmitter is arranged on the electric automobile, the signal transmitter can send out a signal with a unique identity mark, and the signal receiver 13 identifies the signal as a judgment basis;
3. the mobile phone of the user is used as a signal emitter, the mobile phone of the user starts a bluetooth function or an NFC function and sends a signal with a unique identity, and the signal receiver 13 recognizes the signal as a judgment basis.
The signal receiver 13 works in two modes, one is to passively receive the signal from the paired signal source, and the other is to actively detect whether the paired signal source is present in the working range, which can also be used simultaneously.
In an actual application scene, the user drives the electric motor car and gets back to parking stall department or is close to the electric pile department of filling that has the low-voltage circuit breaker disclosed in this application, and signal receiver 13 on the low-voltage circuit breaker is when detecting or receiving the signal that pairs the signal source and send, and main part 11 is turned into closed (circular telegram) state by the disconnection (outage) state, and the electric pile that fills at this moment also turns into the on-state by the off-state.
After the user stops the electric motor car, can use and fill electric pile and charge for the electric motor car, also can use after a period and fill electric pile and charge for the electric motor car. When a user drives the electric vehicle to leave the working range of the signal receiver 13, the low-voltage circuit breaker is switched from a closed state (power-on) to an open state (power-off), and the charging pile is switched from a starting state to a closed state.
Can see through the above-mentioned description, the disclosed low voltage circuit breaker of this application can make and fill electric pile and realize automatic switch-over between start-up and closing, and the user no longer need manual operation switch or use the remote controller to operate, and it is more convenient to use, has especially avoided the problem that fills electric pile that forgets to cause is in the on state all the time.
As a specific implementation of the low-voltage circuit breaker provided by the application, one signal receiver 13 can be paired with multiple signal sources at the same time for pairing, and as an example of the sources of the above-mentioned paired signal sources, the owner of the vehicle can use a signal transmitter or his own mobile phone on the vehicle as the signal source at the same time.
In addition, when a plurality of vehicles in a household share one charging pile, the signal transmitters on the vehicles can be simultaneously bound with one signal receiver 13.
The signal receiver 13 includes a bluetooth signal receiver, an NFC signal receiver, a WiFi signal receiver, and a ZigBee signal receiver. For the low-voltage circuit breaker disclosed by the application, one of the low-voltage circuit breakers can be used, and a plurality of low-voltage circuit breakers can be used simultaneously to meet various use requirements in different scenes.
In one embodiment of the low-voltage circuit breaker, when the signal receiver 13 cannot receive the signal from the paired signal source, the main body 11 is turned off by the control board 12 after the off time is set. That is, when the signal from the paired signal source disappears, the main body 11 will wait for a period of time before disconnecting, which is mainly to avoid the abnormal disconnection of the main body 11 caused by the sudden signal interruption.
It will be appreciated that there is a possibility of sudden signal interruption, and when this occurs, the signal sink 13 and its counterpart signal source should be reconnected, which takes some time, so that the main body 11 will remain closed while the signal sink 13 and its counterpart signal source are reconnected.
Since the main body 11 needs to be turned to the closed (power-on) state after the reconnection is completed, the main body 11 does not need to perform an additional operation of turning to the open (power-off) state and then to the closed (power-on) state when the signal receiver 13 and the signal source paired therewith are reconnected.
In the above description, the signal receiver 13 works in two ways, the first way is to wait for the signal from the paired signal source to reappear, and the second way is to actively search for the paired signal source and send out a connection request. The two working modes can be used alternatively or simultaneously, and when the signal sent by the paired signal source cannot be received within the set disconnection time, the signal receiver 13 disconnects the main body 11 through the control board 12.
Referring to fig. 4 and 5, as an embodiment of the low voltage circuit breaker provided by the application, a communication unit 14 connected to the control board 12 or the signal receiver 13 is added, and the communication unit 14 is used for transmitting an operation signal to a terminal connected thereto.
For example, the terminal may be an electronic parking lock, and when the vehicle bound to the signal receiver 13 moves into the working range of the signal receiver 13, the communication unit 14 sends a signal to the electronic parking lock, and at this time, the electronic parking lock falls down, and the vehicle may move into a parking space; when the vehicle bound with the signal receiver 13 disappears from the working range of the signal receiver 13, the electronic parking space lock is lifted.
For another example, the terminal may also be an intelligent manager in a house or some electric appliance with a connection function, when the vehicle bound to the signal receiver 13 moves into the working range of the signal receiver 13, it is considered that the vehicle owner goes home from work, and at this time, the electric appliance in the house starts to be started according to the set content.
The communication unit 14 may be a wired communication unit, which refers to a hardware device that performs communication by means of wires, optical fibers, and the like.
The communication unit 14 may also be a wireless communication unit including hardware devices using bluetooth, WIFI, zigBee, NB-IOT, GPRS, 4G, loRa, and other technologies.
