Description

Technical Field

[0001] This utility model relates to the field of rail transit industrial control technology, specifically to a high-speed train mechanic's room equipped with an intelligent interactive HMI. Background Technology

[0002] On high-speed trains, the mechanic's cab is the main monitoring area for the onboard mechanic. When on duty, the mechanic can check various train information and control the train through the touchscreen of the HMI (Hardware Management System).

[0003] Touchscreens include capacitive screens. The electromagnetic environment on trains is currently complex and harsh, which can affect capacitive screens. This manifests as follows: when no one is using the capacitive screen, electromagnetic interference can cause it to spontaneously tap certain areas of the screen. If this occurs unattended, it can lead to uncontrollable consequences.

[0004] In addition, the onboard mechanic will perform regular inspections, during which time the mechanic's cab will be unattended, while the HMI will still have control functions, which may pose a risk to driving safety. Utility Model Content

[0031] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. Here, the illustrative embodiments of this utility model and their descriptions are used to explain this utility model, but are not intended to limit this utility model. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be arbitrarily combined with each other.

[0032] Figure 1 This is a structural schematic diagram of a high-speed train mechanic's cab equipped with an intelligent interactive HMI, according to an embodiment of this utility model. Figure 1 As shown in the figure, the EMU mechanic's room equipped with an intelligent interactive HMI provided in this embodiment of the utility model includes:

[0033] Relay 1, camera 2, and HMI 3 are connected in pairs; where:

[0034] Camera 2 and HMI3 are connected via a communication cable for network communication. Relay 1 is electrically connected to Camera 2 via a relay circuit, and Relay 1 is electrically connected to HMI3 via a relay circuit.

[0035] The two contacts of relay 1 are rigidly connected to the mechanic's room door 4. When the mechanic's room door 4 is open, the two contacts of relay 1 are open, and relay 1 outputs a low-level signal. When the mechanic's room door 4 is closed, the two contacts of relay 1 are closed, and relay 1 outputs a high-level signal. Camera 2 and HMI3 receive the high-level signal output by relay 1.

[0036] The two contacts of relay 1 are rigidly connected to the mechanic's room door 4. When the mechanic's room door 4 is opened, the two contacts of relay 1 are open, and relay 1 outputs a low-level signal to control camera 2 to identify personnel in the mechanic's room 4. If no personnel are identified in the mechanic's room 4, a first control command is sent to HMI3. HMI3 receives the first control command and turns off HMI3. When the mechanic's room door 4 is closed, the two contacts of relay 1 are closed, and relay 1 outputs a high-level signal. Camera 2 and HMI3 receive the high-level signal output by relay 1 and maintain the current working state.

[0037] Furthermore, the relay circuit includes a first current-limiting resistor R1 and a relay 1;

[0038] One end of the first current-limiting resistor R1 is connected to the power supply used for circuit power supply, and the other end is connected to the input interface of camera 2 and HMI3; one end of relay 1 is connected to the input interface of camera 2 and HMI3, and the other end is grounded.

[0039] Furthermore, the camera 2 is provided with a camera input port circuit for processing the input signal of the camera 2.

[0040] Furthermore, the camera input port circuit includes a diode D1, a Zener diode D2, a first shunt resistor R2, a second shunt resistor R3, a first pull-down resistor R4, a second pull-down resistor R6, a second current-limiting resistor R5, and an optocoupler D3;

[0041] One end of the diode D1 is connected to the input signal, and the other end is connected to the first shunt resistor R2 and the Zener diode D2;

[0042] The other end of the first shunt resistor R2 is grounded, the other end of the Zener diode D2 is connected to the second shunt resistor R3, the other end of the second shunt resistor R3, one end of the first pull-down resistor R4 and one end of the second current limiting resistor R5 are connected to the optocoupler D3, and the other end of the first pull-down resistor R4 is grounded.

[0043] The other end of the second current-limiting resistor R5 is connected to the output signal and one end of the second pull-down resistor R6, respectively. The other end of the second pull-down resistor R6 is grounded, and the optocoupler D3 is powered by a 5V power supply.

[0044] Furthermore, the camera 2 is provided with a camera output port circuit for processing the input signal of the camera 2.

[0045] Furthermore, the camera output port circuit includes a pull-up resistor R7 and a switching transistor D4 connected in sequence. One end of the pull-up resistor R7 is connected to a 5V power supply, and the other end of the pull-up resistor R7 is connected to the output signal and one end of the switching transistor D4. The other end of the switching transistor D4 is grounded, and the switch of the switching transistor D4 is connected to the input signal.

[0046] Furthermore, camera 2 is a biometric camera.

[0047] Furthermore, the HMI3 includes a capacitive touchscreen, allowing mechanics to access various train information and control the train in emergencies via the touchscreen.

[0048] Furthermore, the HMI3 is powered by a 220V power supply.

[0049] Furthermore, camera 2 and HMI3 are connected via fiber optic network communication.

[0050] The first control command does not carry any identification information; HMI3 receives the first control command and shuts down, which can ensure the safety of train control.

[0051] The control camera 2 identifies the personnel in the mechanic's room 4. If the personnel in the mechanic's room are identified, a second control command is sent to HMI3. HMI3 receives the second control command and activates HMI3, which ensures that the mechanic can perform normal work.

[0052] like Figure 2 As shown, the opening direction of the mechanic's room door 4 is illustrated, as well as the data interaction content between relay 1, camera 2, and HMI3.

[0053] like Figure 3The diagram shows the connection between the contacts of relay 1 and the mechanic's room door 4.

[0054] The mechanic's compartment 4 is equipped with a swing door leading from the carriage corridor. Inside the mechanic's compartment 4 are an HMI 3, a relay 1, and a biometric camera. A relay 1 is mounted on the side of the mechanic's compartment door 4, and the door is connected to relay contacts. The relay contacts are engaged when the mechanic's compartment door 4 is closed and disengaged when it is opened. This relay 1 controls an output signal that is simultaneously output to the HMI 3 and the biometric camera.

[0055] Inside Mechanic Room 4, a biometric camera is positioned facing the same direction as the HMI 3 screen. This camera can recognize the facial features of anyone entering Mechanic Room 4, thus identifying the person. The biometric camera has input and output ports. The input port receives signals from relays, and the output port sends data to the HMI.

[0056] Inside the mechanic's compartment 4, there is an HMI3, which allows users to access various train information via a touchscreen. In emergencies, the train can also be controlled via the touchscreen. The HMI3 can receive input signals and data from relay 1 and the biometric camera.

[0057] The relay circuit controls the two contacts of relay 1 to open when the mechanic's room door is opened, at which time the relay outputs a low-level signal; and the two contacts of relay 1 to close when the mechanic's room door is closed, at which time the relay outputs a high-level signal.

[0058] like Figure 4 As shown, the relay circuit includes a first current-limiting resistor R1 and a relay 1;

[0059] One end of the first current-limiting resistor R1 is connected to the power supply for the circuit, and the other end is connected to the input interfaces of camera 2 and HMI3. One end of relay 1 is connected to the input interfaces of camera 2 and HMI3, and the other end is grounded. The power supply for the circuit can be +5V. The contacts of relay 1 are rigidly connected to the swing door of the mechanic's room 4. When the swing door is open, the contacts of relay 1 open, relay 1 is disconnected, +5V is disconnected from the input interfaces of the biometric camera and HMI3, and the biometric camera and HMI3 detect a low level. When the swing door is closed, +5V is connected to the input interfaces of the biometric camera and HMI3, and the biometric camera and HMI3 detect a high level.

[0060] like Figure 5 and Figure 6As shown, when the input signal is high, the current is shunt after passing through diode D1. The first shunt resistor R2 and the second shunt resistor R3 are used to ensure that the current flowing through optocoupler D3 is within a safe range. Zener diode D2 ensures that optocoupler D3 will not experience overvoltage. When current flows through optocoupler D3, switching transistor D4 will connect 5V to the output signal, at which point the signal is successfully output. The second current-limiting resistor R5 ensures that the output signal will not experience overcurrent, and the second pull-down resistor R6 ensures that the output signal voltage is clamped at a low level when the input signal is low.

[0061] This utility model provides a high-speed train mechanic's compartment equipped with an intelligent interactive HMI, comprising a relay, a camera, and an HMI connected in pairs. The camera and HMI are connected via a communication cable for network communication; the relay and camera are electrically connected via relay circuit lines; the relay and HMI are also electrically connected via relay circuit lines. Two contacts of the relay are rigidly connected to the mechanic's compartment door. When the mechanic's compartment door is open, the two contacts of the relay are open, and the relay outputs a low-level signal; when the mechanic's compartment door is closed, the two contacts of the relay are closed, and the relay outputs a high-level signal. The camera and HMI receive the high-level signal output by the relay, ensuring train control safety.
