Abstract
Description
Technical Field
[0001] This utility model relates to the field of charging pile operation and maintenance control technology, specifically to a remote recovery circuit for the emergency stop button of a charging pile. Background Technology
[0002] With the continuous promotion and popularization of new energy vehicles, the number of electric vehicles on the road continues to rise, and the corresponding charging demand is also increasing. Nowadays, the number of charging stations is growing, and electric vehicle charging stations typically operate on a self-service model. In this situation, charging vehicles may need to press the emergency stop button due to unforeseen circumstances. Furthermore, there are instances of curious users intentionally pressing the emergency stop button. However, most car owners lack the necessary expertise and often cannot restore the vehicle's charging position after the emergency stop button has been pressed.
[0003] When this occurs, the charging station's backend will report a malfunction in the emergency stop button. Normally, maintenance personnel will manually reset the button upon discovering the fault. However, some charging stations lack a monitoring backend. In such cases, maintenance personnel will only manually reset the button when the next user discovers the fault and reports it; or when maintenance personnel discover the fault during on-site inspections. Even at charging stations with backend monitoring, sometimes the emergency stop button can only be reset after an inspection team arrives. Utility Model Content
[0004] The technical problem to be solved by this utility model is to provide a remote recovery circuit for the emergency stop button of a charging pile, so as to solve the problems mentioned in the background art.
[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows.
[0006] A remote recovery circuit for an emergency stop button on a charging pile includes a network module, a control board connected to the network module, and a relay connected to the control board.
[0007] The network module is used to connect to a wireless network or a local wired network to enable remote communication;
[0008] The relay is used to connect the control board and the emergency stop button, thereby achieving physical isolation modification of the emergency stop button;
[0009] The control board is used to collect the real-time status of the emergency stop button and receive instructions transmitted by the network module to control the relay action to realize the emergency stop and recovery of the emergency stop button.
[0010] Preferably, the emergency stop button is connected in parallel with a common terminal of a controlled circuit and a normally open terminal of a controlled circuit of the relay, and the common terminal of the controlled circuit and the normally open terminal of the controlled circuit are connected to the control board output point of the control board.
[0011] Preferably, the control board achieves relay self-locking by controlling the relay, so that the trigger button becomes a normally closed feedback.
[0012] Preferably, the emergency stop button is a self-resetting contact type emergency stop button.
[0013] Preferably, the relay is a JZX_22FD / 4&CDZ9-54PL relay.
[0014] The technological advancements achieved by this utility model are as follows, due to the adoption of the above technical solutions.
[0015] This utility model, through its network module, control board, and relay, enables remote real-time monitoring of the emergency stop button's switch status on charging piles, and remote control of the button's press and release status. This allows for unattended charging station environments, ensuring that the emergency stop button does not require operator intervention, thereby improving charging station service quality, reducing manual intervention, and avoiding resource waste. Attached Figure Description
[0016] Figure 1 This is the circuit diagram of this utility model. Detailed Implementation
[0017] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.
[0018] A remote recovery circuit for the emergency stop button of a charging pile, combined with Figure 1 As shown, it includes a network module, a control board, and a relay, with the control board connected to the network module and the relay connected to the control board.
[0019] The network module is used to connect to a wireless network or a local wired network to enable remote communication with the background monitoring system.
[0020] The relay is used to connect the control panel and the emergency stop button, enabling physical isolation of the emergency stop button. Specifically, the relay is a JZX_22FD / 4&CDZ9-54PL relay, and the emergency stop button is a self-resetting contact type. The emergency stop button and the relay share a common terminal in a controlled circuit (e.g., ...). Figure 1 The relay controlled circuit 1 common terminal 5) and a controlled circuit normally open contact (such as...) Figure 1 The normally open contact 9 of the relay controlled circuit 1 is connected in parallel, and the common terminal of the controlled circuit (common terminal 5 of relay controlled circuit 1) and the normally open contact of the controlled circuit (normally open contact 9 of relay controlled circuit 1) are connected to the control board output point (e.g., ...) of the control board. Figure 1 Connect the control board output point 1).
[0021] The control board collects the real-time status of the emergency stop button and receives commands transmitted from the network module to control the relay action, thereby controlling the emergency stop button's emergency stop and recovery. The control board controls the relay to achieve relay self-locking, causing the trigger button to switch to normally closed feedback. This allows the local emergency stop button to enter the emergency stop state when pressed, and to have no effect when pressed again. The self-locking state is broken remotely, restoring the emergency stop button's state, thus achieving remote recovery. Furthermore, the control board provides real-time status feedback through the relay's controlled circuit, which is connected to the charging pile's emergency stop circuit to realize the original function of the emergency stop button.
[0022] The working principle of this utility model is as follows: by controlling the relay to achieve relay self-locking, the trigger button is converted into a normally closed feedback method, thereby modifying the local emergency stop button. The specific working principle is as follows:
[0023] (1) Emergency stop button status monitoring: The relay collects the status of the emergency stop button in real time and transmits it to the network module through the control board.
[0024] (2) Remote control: The control board receives remote commands through the network module and controls the relays according to the commands.
[0025] (3) Emergency stop button recovery: When the emergency stop button is pressed and enters the emergency stop state, pressing it again will have no effect. The emergency stop button state is recovered by remotely disconnecting the self-locking state of the relay.
[0026] (4) Real-time status feedback: Real-time status feedback is achieved through the controlled circuit of the relay to ensure that the status of the emergency stop button can be transmitted to the background monitoring system in real time.
