Description

Technical Field

[0001] This utility model relates to the field of turnstile alarm technology, and more specifically, to a subway turnstile alarm transmission device. Background Technology

[0002] A turnstile is a channel blocking device, mainly used in urban rail transit management and fare gate systems to manage pedestrian flow and regulate pedestrian access.

[0003] In subway turnstiles, if an abnormal situation occurs, the turnstile itself will sound an alarm and issue a light warning to alert staff of the malfunction. However, in actual use, both the sound and light alarms are on the turnstile itself. To ensure unobstructed passage of people, staff are generally not stationed near the turnstiles; instead, they are usually on duty at the control panel or other locations. Therefore, alarm information is often not delivered immediately, resulting in excessive delays. Utility Model Content

[0004] The technical problem to be solved by this utility model is that the alarm of the turnstile is not timely in the prior art. In order to overcome the above-mentioned defects of the prior art, this utility model provides a subway turnstile alarm transmission device.

[0005] This utility model provides a subway gate alarm transmission device, including an alarm detection module installed next to the gate and a wireless receiver installed in the central control room;

[0006] The alarm detection module includes a sound pickup module for picking up abnormal prompts from the turnstile and a wireless transmission module for transmitting alarm signals generated by the sound pickup module. The sound pickup module is located on one side of the alarm inside the turnstile. The wireless receiver includes a wireless receiving module for receiving alarm signals and an alarm module for issuing alarms. The sound pickup module is electrically connected to the wireless transmission module, the wireless transmission module is communicatively connected to the wireless receiving module, and the alarm module is electrically connected to the wireless receiving module.

[0007] Compared with the prior art, the subway gate alarm transmission device proposed in this application has the following advantages: when the gate malfunctions, the sound pickup module inside the gate can pick up the alarm sound and transmit the alarm information through the wireless transmission module. After receiving the alarm, the wireless receiving module can promptly provide a prompt through the alarm module, ensuring that the gate malfunction information can be received and processed in a timely manner.

[0008] In one possible implementation, the sound pickup module includes an audio chip U3 and a pickup head. The positive input of the audio chip U3 is grounded through a resistor R5 and a capacitor C7. The positive input of the audio chip U3 is also grounded in series with a resistor R3, a resistor R6, and a capacitor C11. The negative input of the audio chip U3 is electrically connected to the output terminal of the pickup head in series with a resistor R4 and a capacitor C10. The output terminal of the pickup head is grounded in series with a resistor R7 and a capacitor C11. The output terminal of the audio chip U3 is electrically connected to a wireless transmission module.

[0009] Compared with existing technologies, sound is picked up by a microphone and processed by an audio chip U3. The processed information is then transmitted to a wireless transmission module, which facilitates the transmission of alarm information.

[0010] In one possible implementation, the wireless receiver is provided with a first indicator light for indicating that the wireless transmitting module and the wireless receiving module are not connected, and a second indicator light for indicating that the wireless transmitting module and the wireless receiving module are connected. Both the first indicator light and the second indicator light are electrically connected to the wireless receiving module.

[0011] Compared with existing technologies, the first and second indicator lights make it easy to identify whether the wireless transmitting module and the wireless receiving module are connected. Only when the two are connected can they be used normally, ensuring that alarm information can be transmitted to the central control console in a timely manner.

[0012] In one possible implementation, the first indicator light is green and the second indicator light is blue.

[0013] In one possible implementation, the alarm module includes a third indicator light and a buzzer for displaying alarm information, both of which are electrically connected to the wireless receiving module.

[0014] Compared with existing technologies, the third indicator light provides a visual alarm, while the buzzer provides an audible alarm. These two alarm methods promptly alert the staff at the central control station, making the alarm notification more prominent.

[0015] In one possible implementation, the third indicator light is a red light.

[0016] In one possible implementation, the alarm detection module is provided with a reset button for resetting the wireless transmission module, and the reset button is electrically connected to the wireless transmission module.

[0017] Compared with existing technologies, when the wireless transmitter and receiver modules are not connected, the wireless transmitter module can be restarted by using the reset button, making it easy for the wireless transmitter and receiver modules to reconnect.

[0018] In one possible implementation, the receiver is provided with a cancel button for stopping the alarm module from displaying the alarm signal, and the cancel button is electrically connected to the wireless receiver module.

[0019] Compared with existing technologies, after receiving and handling the alarm information, the staff at the central control station can clear the alarm by pressing the clear button, which facilitates the re-testing and ensures that the gate alarm can be transmitted for a long time, so that the alarm is timely.

[0020] In one possible implementation, both the wireless transmitting module and the wireless receiving module are ESP32S3 modules.

[0021] In one possible implementation, the audio chip U3 is a MAX4466EXK+ audio power amplifier. Attached Figure Description

[0027] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0028] See Figures 1-2 As shown in the figure, this application discloses a subway gate alarm transmission device, including an alarm detection module installed next to the gate and a wireless receiver installed in the central control room.

[0029] The alarm detection module includes a sound pickup module for picking up abnormal prompts from the turnstile and a wireless transmission module for transmitting alarm signals generated by the sound pickup module. The sound pickup module is located on one side of the alarm inside the turnstile. The wireless receiver includes a wireless receiving module for receiving alarm signals and an alarm module for triggering alarms. The sound pickup module is electrically connected to the wireless transmission module, the wireless transmission module is communicatively connected to the wireless receiving module, and the alarm module is electrically connected to the wireless receiving module.

[0030] When the turnstile malfunctions, the sound pickup module inside the turnstile can pick up the alarm sound and transmit the alarm information through the wireless transmission module. After receiving the alarm, the wireless receiving module can promptly notify the user, ensuring that the turnstile malfunction information is received as soon as possible and handled in a timely manner.

[0031] In this embodiment, both the wireless transmitting module and the wireless receiving module are ESP32S3 modules, which transmit wirelessly via WiFi. Of course, in practice, radio communication or 4G / 5G networks can also be used for transmission.

[0032] The sound pickup module includes an audio chip U3 and a pickup head. The pickup head is set on the side of the alarm transmitter inside the gate, which makes it easier to identify the alarm sound more accurately and prevents interference from the sound of people and the alarm sounds in other adjacent gates.

[0033] The positive input of audio chip U3 is grounded through resistor R5 and capacitor C7. The positive input of audio chip U3 is also grounded in series with resistor R3, resistor R6 and capacitor C11. The negative input of audio chip U3 is electrically connected to the output of the pickup head in series with resistor R4 and capacitor C10. The output of the pickup head is grounded in series with resistor R7 and capacitor C11. The output of audio chip U3 is electrically connected to the wireless transmission module.

[0034] Sound is picked up by a microphone, and the information is processed by the audio chip U3. The processed information is then transmitted to the wireless transmission module, which then transmits alarm information.

[0035] In this embodiment, the audio chip U3 is a MAX4466EXK+ audio power amplifier.

[0036] The wireless receiver is equipped with a first indicator light to show that the wireless transmitter module and the wireless receiver module are not connected, and a second indicator light to show that the wireless transmitter module and the wireless receiver module are connected. Both the first indicator light and the second indicator light are electrically connected to the wireless receiver module.

[0037] The first and second indicator lights make it easy to identify whether the wireless transmitter and receiver modules are connected. Only when they are connected can they be used normally, ensuring that alarm information can be transmitted to the central control console in a timely manner.

[0038] In this embodiment, the first indicator light is green, and the second indicator light is blue. Of course, in actual use, to facilitate adjustment of the light color, tri-color LEDs can be used for indication, with different colors displaying different states.

[0039] The alarm module includes a third indicator light and a buzzer for displaying alarm information. Both the indicator light and the buzzer are electrically connected to the wireless receiver module. The third indicator light provides a visual alarm, while the buzzer provides an audible alarm, offering both methods to promptly alert the control room staff and making the alarm notification more prominent.

[0040] In this embodiment, the third indicator light is red. The third indicator light can also be indicated using a tri-color LED.

[0041] The alarm detection module is equipped with a reset button for resetting the wireless transmission module, and the reset button is electrically connected to the wireless transmission module.

[0042] When the wireless transmitter and receiver modules are not connected, the wireless transmitter module can be restarted by using the reset button, which will allow the wireless transmitter and receiver modules to reconnect.

[0043] In this embodiment, the receiver is equipped with a clear button for stopping the alarm module from displaying the alarm signal. The clear button is electrically connected to the wireless receiver module. After receiving and processing the alarm information, the staff at the central control station can clear the alarm by pressing the clear button, facilitating subsequent testing and ensuring that the gate alarm is transmitted for an extended period, providing timely alarm response.

[0044] Working principle: First, after both the alarm detection module and the wireless receiver are powered on, check whether the first indicator light and the second indicator light on the wireless receiver are lit. If the first indicator light is lit, it means that the wireless transmitter module and the wireless receiver module are not connected. At this time, press the reset button on the alarm detection module to restart the wireless transmitter module until the second indicator light on the wireless receiver is lit. If the second indicator light is lit directly, it means that the wireless transmitter module and the wireless receiver module are connected.

[0045] Then, the sound pickup module in the alarm detection module processes the sound information after detecting an alarm inside the turnstile, generates an alarm message, transmits it via the wireless transmitter, receives it via the wireless receiver, and displays it through the alarm module, alerting staff at the control panel to take action. This achieves the function of alarm transmission and timely notification. Finally, after the staff has resolved the turnstile malfunction, they can press the clear button on the receiver to re-detect the turnstile for reuse.
