Description

Technical Field

[0001] This utility model relates to the field of urban rail transit, specifically to a microcontroller-based train arrival alarm and auxiliary braking system for a subway depot test track. Background Technology

[0002] The test track is a crucial location for dynamic debugging and performance testing of trains at the Nanning Metro depot. Train drivers maneuver the train back and forth on the test track to conduct test programs. A stop marker is placed 100 meters before the end of the test track. When turning back, the driver must bring the train to a complete stop before this marker. Currently, the driver relies solely on manually confirming the stopping position and applying the brakes, without corresponding technical assistance. This poses a significant safety hazard due to driver negligence in failing to stop in time, causing the train to run off the test track. To address this, a microcontroller-based train arrival alarm and auxiliary braking system for the metro depot test track has been invented. This system can remind the driver to brake at the stop marker on the test track and can assist in applying the brakes, thus preventing safety hazards. Summary of the Invention

[0003] To achieve the purpose of this invention, the technical solution adopted by this utility model is: a train arrival alarm and auxiliary braking system based on a microcontroller for a subway depot test track. It includes a power supply, a main controller, a slave controller, sensors, an LCD screen, a voice announcer, an audible and visual alarm, a wireless transmission module, relays, and switches. The main controller is connected to the power supply, LCD screen, voice announcer, audible and visual alarm, wireless transmission module, and relays. The slave controller is connected to the power supply, sensors, and wireless transmission module. When the sensors detect the train's arrival, the slave controller transmits the data collected by the sensors to the main controller via the wireless transmission module. After receiving the data, the main controller controls the LCD screen, voice announcer, audible and visual alarm, and relays to operate, thereby reminding the driver to brake and assisted in applying the brakes.

[0004] The power supply is a switching power supply; the main controller is an STC89C52RC microcontroller; the slave controller is an STC89C51 microcontroller; the sensor is an XUX5ANANT16 photoelectric sensor; the LCD screen is an LCD12864 LCD screen; the voice broadcaster is a BY8301-16P voice broadcaster; the audible and visual alarm is an LB22FM audible and visual alarm; the wireless transmission module is an HC-14 wireless transmission module; the relay is a JZX-22F relay; and the switch button is a normally closed type switch.

[0009] The technical solution of the invention will be described in detail below with reference to the accompanying drawings:

[0010] A microcontroller-based train arrival alarm and auxiliary braking system for a subway depot test track, such as Figure 1 The diagram shown illustrates the structural principle of this utility model for acquiring train position information from a controller. It includes a switching power supply, an STC89C51 microcontroller, a XUX5ANANT16 photoelectric sensor, and an HC-14 wireless transmission module. Its key feature is that after receiving information from the XUX5ANANT16 photoelectric sensor, the STC89C51 microcontroller transmits the information to the STC89C52RC microcontroller via the HC-14 wireless transmission module.

[0011] like Figure 2 The diagram shown is a schematic of the main controller structure of this utility model. It includes a switching power supply, an STC89C52RC microcontroller, an LCD12864 liquid crystal display screen, a BY8301-16P voice announcer, an LB22FM audible and visual alarm, an HC-14 wireless transmission module, and a JZX-22F relay. Its implementation features are: after receiving train arrival information data transmitted by the HC-14 wireless transmission module, the STC89C52RC microcontroller controls the LCD12864 liquid crystal display screen to display the train arrival information, the BY8301-16P voice announcer to broadcast the train arrival voice message, the LB22FM audible and visual alarm to activate, and the JZX-22F relay coil to engage, causing the train to brake and stop.

[0012] like Figure 3 The diagram shown illustrates the electrical connection principle between the microcontroller and the relay in this invention. It includes an STC89C52RC microcontroller and a JZX-22F relay coil. The key feature of this implementation is that the JZX-22F relay coil is connected to the STC89C52RC microcontroller. When the STC89C52RC microcontroller receives train arrival information, it drives the JZX-22F relay coil to engage.

[0013] like Figure 4The diagram shows the connection principle of the relay and train braking system according to this utility model. It includes a normally closed switch and a normally open contact of a JZX-22F relay. The key feature is that the normally open contact of the JZX-22F relay is connected in series with the train braking system and the normally closed switch to form a circuit. When the coil of the JZX-22F relay is energized, its normally open contact closes, connecting the circuit of the train braking system and initiating braking. Pressing the normally closed switch disconnects the braking circuit, releasing the train's braking force, and allowing the train to operate normally.
