1. System Overview
The highway tunnel and control tr*ning system is based on the highway tunnel model as the framework, and all subsystems of the highway tunnel (including ventilation, lighting, fire protection , traffic control, and monitoring subsystems) are completely placed in the highway model for design. , reflecting the actual design content and form of the highway tunnel as much as possible. This product is one of the most important and complex products in the highway tr*ning series. It is m*nly suitable for "intelligent transportation engineering", "road transportation and management", "high-level highway m*ntenance and management", "traffic safety and Practical tr*ning and teaching in related majors such as "Intelligent Control".
2. Product Features 1. The highway tunnel and control tr*ning system uses model design as the framework and is designed according to the design content and form of the actual highway tunnel, which can truly meet the teaching needs of highway tunnels in
transportation colleges . 2. The tunnel ventilation subsystem, tunnel lighting subsystem, tunnel firefighting subsystem, tunnel traffic control subsystem, and tunnel monitoring subsystem in the expressway are designed separately to make the tr*ning level clearer and more convenient. 3. The carbon monoxide (CO) and visibility detector signal outputs are designed in the form of scenario simulation, making the tr*ning process more convenient and vivid. 4. The tunnel variable information boards and lane indicators use microcontroller programming and large LED displays. Students can also carry out secondary design and programming of the system during the tr*ning process . 5. In addition to completing the design and operation tr*ning of each subsystem in the tunnel, students can also program the controller and configure the host computer monitoring interface in the tunnel central control room . 3. Technical parameters 1. Working power supply: AC380V±10% 50Hz 2. Working environment: Ambient temperature range is -20℃～+45℃ Relative humidity <85% Altitude <4000m 3. Overall dimensions: L (along the tunnel)× W (tunnel width) × H (tunnel height) = 4m × 1.8m × 2.3m IV. Basic configuration 1. Tunnel model The tunnel model consists of the tunnel approach section and entrance section model, the tunnel basic section model, the tunnel extension section model, and the tunnel exit The segment model consists of four parts. The model frame of each section of the tunnel is designed using aluminum alloy profiles. Except for the close section of the tunnel, each section of the model consists of two tunnel walls (the upper part of each wall is a mesh plate for equipment installation, and the lower part is a solid) model, and a sidewalk model , ceiling (including top beams) and floor. The tunnel approach section and entrance section, tunnel basic section, tunnel extension section, and tunnel exit section are sequentially connected by connecting blocks. The maximum height of the entire tunnel model is 2.3 meters and the length is approximately 4 meters (including the tunnel access section) 2. Tunnel ventilation subsystem The tunnel ventilation subsystem m*nly includes axial flow fans, carbon monoxide (CO) and visibility (VI) simulation detectors , wind speed (WS) detector, fan control cabinet and other equipment. 3. Tunnel lighting subsystem The m*n equipment of the tunnel lighting subsystem includes brightness detectors, simulated light sources, emergency lighting, three-proof lights, ceiling lights, lighting distribution cabinets, lighting controllers, etc. 4. Tunnel fire protection subsystem The m*n equipment of the tunnel fire protection subsystem includes manual alarm buttons, flame detectors, fire boxes (including fire hydrants, hoses, water guns, portable CO2 fire extinguishers, portable dry powder fire extinguishers and other equipment), sirens, fire control Devices etc. 5. Tunnel traffic control subsystem The m*n equipment of the tunnel traffic control subsystem includes vehicle detectors, lane indicators, variable information boards, various signs (such as variable speed limit signs, height limit signs, tunnel signs, etc.), traffic control Devices etc. 6. Tunnel monitoring subsystem The tunnel monitoring subsystem consists of a video monitoring subsystem, ventilation, fire protection, lighting and other systems and monitoring software. The tunnel video surveillance subsystem m*nly consists of spherical cameras, color cameras, monitors, hard disk video recorders, matrices and other equipment. 7. Tunnel Central Control Room The m*n equipment of the tunnel monitoring center includes monitoring system monitors, matrices, hard disk video recorders, controllers for each tunnel subsystem ( Siemens S7-200 plc and analog input and output modules), sound and light alarms, and tunnel detection instrument display, tunnel and tunnel equipment power supply, frequency converter and other equipment. 8. Teacher teaching design system: This system is in apk format and can be used on PC or mobile. This system can set faults manually or automatically. This system selects manual through the green box in the circuit diagram. Set fault points (up to 39 fault points can be set), or you can automatically set one fault point randomly through the system, set two fault points randomly, set three fault points randomly, set four fault points randomly, and set five fault points randomly. For fault point setting, this system has functions such as toolbox, component library, magnifying glass, circuit diagram, etc. You can select a multimeter for detection through the toolbox, select appropriate components through the component library, and clearly understand each component and circuit through the magnifying glass. This system allows students to understand the working principle and circuit structure of the motor star-delta start control circuit through the setting of faults in the motor star-delta start control circuit and various investigations. 9. Three-purpose meter simulation software: This software is in apk format and can be used on the PC or mobile terminals. The functions of this software are: measurement of resistance, measurement of AC voltage (measuring transformer, if the transformer measurement burns out) When the multimeter is broken, black smoke will appear and the multimeter can be reset), transistor polarity judgment, DC voltage measurement (the light turns on when the ammeter is turned on), DC current measurement, and judgment of the quality of the capacitor. This software can drag the red and black pen tips at will. When the two pen tips are dragged and positioned on the object to be measured, a red circle will be displayed. If the positioning is not accurate, no red circle will be displayed, and when incorrect operations are performed (such as the wrong range selected, If the measured data is wrong, etc.), the meter pointer will be unresponsive, prompting errors and re-measurement, etc. This multimeter can select AC voltage range, DC voltage range, resistance range, current range, resistance adjustment to 0, and can enlarge the display data. Clearly view the measured data size. Students can learn the correct use of multimeters through this software.
