Description

Technical Field

[0001] The utility model belongs to the technical field of recovery circuits, and in particular relates to a one-button recovery device for emergency release of a gate machine under hard-line control. Background Art

[0002] Urban rail transit systems are a vital component of my country's transportation system. As passenger-facing terminals of the Automatic Fare Collection (AFC) system, their operational reliability is directly linked to the passenger experience. Gates, installed in station concourses, perform ticket reading and writing, ticket checking and billing, and passenger release. In the event of a power outage in the AFC equipment room's power distribution box, a fault in the gate emergency controller itself, or a power outage, all gates in the station are released, leaving the doors permanently open. The current solution involves on-site restoration of each gate individually, which is slow and can lead to unilateral passenger travel and mismatched entry and exit sequences. Utility Model Content

[0003] The present invention aims to solve the above technical problems at least to a certain extent. To this end, the present invention aims to provide a one-button recovery device for emergency release of a gate with hard-wire control.

The emergency controller is provided with a first terminal. The control box is provided with a DC relay, a DC power supply, a first terminal block and a second terminal block. The control box is provided with a second terminal block and a third terminal block. The first terminal block is connected to the second terminal block, the second terminal block is connected to the third terminal block through the DC relay, and the third terminal block is connected to the gate machine; the DC power supply is connected to the first terminal block and a recovery button, the recovery button is connected to the second terminal block, and the first terminal block and the second terminal block are both connected to the DC relay.

[0006] Preferably, the emergency controller is provided with a three-core socket connected to a DC power supply. The gate is provided with multiple groups of DC relays, the number of which is the same as the number of gates. The recovery button is a self-locking switch button.

BRIEF DESCRIPTION OF THE DRAWINGS

[0009] Figure 1 It is a schematic diagram of the utility model of a gate machine hard-line controlled emergency release one-button recovery device. DETAILED DESCRIPTION

[0010] The following will be combined with the accompanying drawings to clearly and completely describe the technical solution of the present invention. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0011] It should be understood that it should also be noted that in the embodiments, the functions / actions that appear may be different from the order in which the figures appear. For example, depending on the functions / actions involved, they may actually be performed substantially concurrently, or two figures shown in succession may sometimes be performed in the reverse order.

[0012] like Figure 1 As shown, the gate hard-wired controlled emergency release one-button recovery device of this embodiment mainly includes an emergency controller 1, a control box 12 and four groups of gates 6. The emergency controller 1 is provided with a first terminal 2, and the emergency controller 1 outputs four groups of DC24V. The control box 12 is provided with four DC relays 4, a DC power supply 8, a first terminal block 9 and a second terminal block 10. The control box 12 is provided with a second terminal 3 and a third terminal 5. The four groups of wires of the first terminal 2 are connected to the second terminal 3, and the four groups of wires of the second terminal 3 are respectively connected to the third terminal 5 through four DC relays 4, and the four groups of wires of the third terminal 5 are respectively connected to the four groups of gates 6.

[0013] Emergency controller 1 is equipped with a three-core socket 7, which is connected to a DC power supply 8. This socket is used to connect to the mains power supply and features leakage protection to ensure that a fault in the control box circuit does not affect the upper power circuit. DC power supply 8 is connected to a first terminal block 9 and a restore button 11. The restore button 11 is connected to a second terminal block 10. The four sets of wires from the first terminal block 9 and the four sets of wires from the second terminal block 10 are connected to four DC relays 4, respectively.

[0014] The control box 12 is installed in the AFC equipment room or the train control room. The recovery button 11 is a self-locking switch button. The recovery button 11 can be extended and installed in the train control room. The recovery button 11 is operated by station personnel to instantly restore the gates of the entire station, thereby minimizing the impact of unilateral passenger travel and mismatched entry and exit sequences, improving fault handling efficiency, and reducing ticket revenue losses.

[0015] The gate machine hard-wired control emergency release one-button recovery device in this embodiment is disconnected from the AFC equipment room power supply, and a new DC24V line is added from the vehicle control room as a backup. The DC relay 4 normally closed contact control is used to form a separate circuit with each group of gate machines 6 on site. The control box 12 is designed between the emergency controller 1 and the gate machine 6. Normally, the DC relay 4 is not energized, and the emergency controller 1 still outputs a high-level DC24V to the gate machine 6, so that the gate machines of the entire station work normally.

[0016] If the AFC equipment room's power distribution box loses power, the emergency controller itself malfunctions, or loses power, emergency controller 1 outputs 0V, causing all station gates to release in an emergency and the doors to remain open. Pressing restore button 11 closes the normally open contacts of DC relay 4, opening the normally closed contacts and outputting 24V DC to each gate group on-site, restoring the hard-wired emergency release failure for all gates. At this point, the control box and gates are completely disconnected from the emergency controller and the AFC equipment room. If the emergency controller is suddenly powered up while the circuits in control box 12 are operating, the gates will still be powered by the circuits in control box 12, with no impact on on-site equipment.

[0017] The one-button recovery device for hard-wired emergency release of gate machines makes up for the low efficiency of the existing hard-wired emergency release failures of all gate machines in the station, which need to be handled one by one. Under the same environment, technically skilled personnel use the original handling method to test (response plus handling): the total time for single-person single-station testing is 20 minutes, and the total time for testing using the one-button recovery device for hard-wired emergency release of gate machines is 2 minutes per person per station, which greatly improves the efficiency of fault handling.

[0018] At the same time, the recovery button 11 is set in the train control room. The operation is simple and clear, and it can provide convenient, fast and highly mobile recovery conditions. It can quickly restore the emergency release failure of the hard-line control of the gates in the entire station. The recovery button 11 can be operated by station personnel, which improves the efficiency of fault handling and minimizes the impact of unilateral passenger travel and mismatched entry and exit order, while effectively reducing ticket revenue losses.

[0019] The present invention is not limited to the above-mentioned optional implementation methods. Anyone can derive various other forms of products under the inspiration of the present invention. However, no matter what changes are made in the shape or structure, any technical solution that falls within the scope defined by the claims of the present invention shall fall within the scope of protection of the present invention.
