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.
Fig. 1 is a schematic diagram of a grounding system provided by an embodiment of the present invention, the system including:
the ground wire grounding pile is arranged on the ground, a grounding wire is connected to a grounding wire joint, and an RFID (radio frequency identification) card and an RFID 102 are respectively arranged on the grounding wire joint and the grounding wire grounding pile;
the side face of the ground wire connector is provided with a disconnection sensor 104, the disconnection sensor 104 and the RFID 102 are both connected with the controller 103, and the controller 103 is respectively connected with an alarm 105 and the wireless transceiver 101.
Fig. 2 is a schematic diagram of a grounding system according to an embodiment of the present invention, where the disconnection sensor may be a correlation sensor 202, an emitting end of the correlation sensor is disposed on one side of an upper end of the wireless ground wire grounding pile 203, and a receiving end of the correlation sensor is disposed on the other side of the upper end of the wireless ground wire grounding pile. If the light emitted from the emitting end of the correlation sensor is blocked by the ground wire 201 and the receiving end of the correlation sensor does not receive the signal, the ground wire is connected well. And if the receiving end of the correlation sensor receives the signal, the ground wire is not connected.
The conical end of the wireless ground wire grounding pile can be pulled out and inserted for grounding, and the wireless ground wire grounding pile can also be fixed on the rail through a fixing bracket and connected with the rail through a bolt and a lead; when the ground wire joint is connected with the wireless ground wire grounding pile, equipment needing grounding is communicated with the ground through the ground wire and the wireless ground wire grounding pile to finish grounding.
And a ground wire locking structure for locking or unlocking the ground wire is arranged on the wireless ground wire grounding pile. The ground wire locking structure is the prior art. The ground wire locking structure is controlled by the controller to unlock the locked ground wire.
The ground wire connector is provided with a ground wire connecting part and a wireless ground wire grounding pile connecting part.
Wherein the ground wire terminal includes: the ground wire connector main body is positioned at one end part of the ground wire connector main body and is a cable bolt connecting device connected with a ground wire; the connecting part of the wireless ground wire grounding pile is a stud arranged at the other end of the ground wire joint main body and a butterfly nut matched with the stud.
Wherein the controller includes: a PLC controller.
When the ground wire joint for connecting the ground wire is connected with the wireless ground wire grounding pile, the RFID radio frequency identifier on the wireless ground wire grounding pile identifies the RFID radio frequency card on the ground wire joint and sends the identification result to the controller, the wire breakage sensor acquires information on whether the ground wire is well connected and uploads the information to the controller, and the controller controls the alarm to be turned on or not according to the identification result and the information on whether the ground wire is well connected. And when the identification result received by the controller is that the RFID radio frequency card is not identified and the ground wire is well connected, the controller controls the alarm to be started and sends an alarm signal to external terminal equipment through the wireless transceiver. And when the identification result received by the controller identifies that the RFID radio frequency card is not connected with the ground wire, the controller controls the alarm to be started and sends an alarm signal to external terminal equipment through the wireless transceiver. And only when the identification result received by the controller is that the RFID radio frequency card is identified and the ground wire is well connected, the controller does not control the alarm to be started and sends a signal of good ground wire connection to external terminal equipment through the wireless transmitter.
