Technical Field

The invention relates to the technical field of ground wire management, in particular to an intelligent ground lock, a ground wire pile and a ground wire management system.

Background

In order to prevent major safety accidents from occurring in a power grid of a power system and prevent serious misoperation accidents caused by closing of a live grounding wire, the conventional power system mainly strengthens the management of the grounding wire and operators using the grounding wire through a system so as to reduce the accident occurrence probability, but the accidents cannot be fundamentally avoided due to carelessness and carelessness of the operators.

In the prior art, there is a solution: the ground wire head or the ground wire pile of the ground wire is provided with a ground lock (a temporary padlock or a fixed lock), and the state of hanging or removing the ground wire is often characterized by the unlocking operation of unlocking equipment on the ground lock. In practical application, the problem of idle running caused by the fact that unlocking equipment carries out unlocking operation on a grounding lock and a grounding wire is not hung or detached on a grounding wire pile is found in the solution.

In the prior art, there is another solution (CN 110409929A): the ground wire lockset comprises a ground wire detection assembly, the ground wire detection assembly comprises a sensing unit (a reed pipe) and a sensed unit (a magnetic element), the sensed unit is arranged on the lock control part, the sensing unit is arranged on the lock body, and the installation position of the sensing unit meets the following conditions: when the plug connector is located at the lock control position, the sensing unit can sense the sensed unit. When a sensing unit (reed switch) of the ground wire lockset detects that a magnetic element is inserted or pulled out, the code value of the code chip of the ground wire detection assembly changes, and the state of hanging or removing the ground wire is represented. In practical applications, it was found that the sensed unit (magnetic element) on the plug of the ground wire of this solution is easily counterfeited, and there is a "lost motion" problem in that the ground wire is not hooked or removed from the ground wire pile.

In the prior art, although there is a technical scheme such as adopting the anti-misoperation lockset (traditional temporary padlock or fixed lockset) to manage and control the ground wire, the following disadvantages still exist:

1. the identification of the ground wire head identity is not involved, and the information of the ground wire head matched with the ground wire pile for use cannot be obtained, so that the ground wire head is not an appointed ground wire head to cause danger;

2. when the ground wire pile locks the ground wire head of the ground wire, manual operation is needed to execute locking action, locking verification on the ground wire head cannot be completed in an electric error prevention mode, and the problem that manual operation fails to result in incomplete locking exists.

In order to solve the safety problem that misoperation is easy to occur due to disordered ground state management in the prior art, the invention provides an intelligent ground lock, a ground wire pile and a ground wire management system.

When the intelligent grounding lock of the embodiment is connected with a grounding wire, the unlocking terminal acquires a first identity of the intelligent grounding lock, and controls the locking mechanism module 20 of the intelligent grounding lock to open under the condition that the first identity is matched with a first preset identity stored in the unlocking terminal; under the condition that the intelligent ground lock is opened, the control circuit module 50 acquires a second identity of the ground wire head 120 inserted into the ground wire pile through the identity acquisition module 30, and transmits the second identity to the unlocking terminal through the data communication module 40; under the condition that the second identity can be identified and authenticated by the unlocking terminal, the unlocking terminal controls the locking mechanism module 20 of the intelligent grounding lock to lock, so that the ground wire head 120 is hooked with the corresponding ground wire pile. In this way, when the ground wire head 120 is hooked, the locking mechanism module 20 is controlled to unlock the intelligent ground lock only when the first identity identifier of the intelligent ground lock matches the first preset identifier stored in the unlocking terminal. On this basis, after the ground wire head 120 is inserted into the intelligent grounding lock, the control circuit module 50 obtains the second identification of the ground wire head 120 through the identification acquisition module 30, and only when the second identification of the ground wire head 120 can be identified and authenticated by the unlocking terminal, the locking mechanism module 20 is controlled to lock the intelligent grounding lock, and at this time, the ground wire head 120 is hooked successfully. Therefore, the specific ground wire head 120 can be ensured to be hooked with the specific intelligent ground lock, the management order can be obviously improved, the situation of wrong hooking of the ground wire head 120 can be avoided, and the operation accuracy is ensured.

Thus, when the ground wire is connected, the unlocking terminal firstly acquires the first identity to identify the intelligent ground lock, then acquires the second identity through the identity acquisition module 30 of the intelligent ground lock to identify the ground wire head 120, and sequentially completes identification of the intelligent ground lock and the ground wire head 120. In order to cooperate with the identity identification authentication, the unlocking operation of the intelligent grounding lock and the plugging and unplugging operation of the ground wire head are strictly in accordance with the preset safety logic, and each link has a technical means which can be verified.
