Description

Technical Field

[0001] The utility model relates to the field of monorail train cleaning control, in particular to an automatic monorail train washing control system. Background Art

[0002] Cleaning of rail vehicles is a basic operation in the daily maintenance of rail vehicles. Traditional cleaning is done manually, but due to the large size of rail vehicles, manual cleaning is time-consuming and labor-intensive and cannot meet the needs of maintenance. Automated cleaning has emerged. Automated cleaning means that after the vehicle is driven to a designated cleaning station, a cleaning system installed at the cleaning station automatically cleans the vehicle. The automatic cleaning system mainly uses a nozzle to spray water and a roller structure with a brush to clean and scrub the surface of the vehicle body to wash out dust and dirt on the vehicle body. For example, a rail vehicle all-round cleaning device with patent application number 201621388649.6 discloses a fixed rod, a trolley, a water tank, a water pump, a fixed ring, a first bracket, a hose, a water gun, a first rotating motor, a winding wheel, a gear, a rack, a fixed frame, a sliding sleeve, a cam, a second rotating motor, a guide rod, a first fixed pulley, a pull wire, a slide rail, a spring, a slider, a second bracket, a fan, a support rod, a fixed plate and a second fixed pulley; a fixed rod is provided in the middle of the top of the trolley. This patent document uses a water spray gun and a motor to clean the rail vehicle.

[0003] The core components of automatic rail vehicle cleaning are motor-driven scrubbing equipment and water spray nozzles, both of which are electronically controlled. Before entering the cleaning station, the vehicle's doors, air conditioning, and wipers are generally required to be manually closed or adjusted to their set positions. However, manual operation can result in incomplete handling and inability to detect and judge the vehicle's condition. Forgetting to manually close the vehicle's doors, or failing to detect a door failure due to a malfunction in the vehicle's equipment can lead to damage to the vehicle, impacting the reliability of the automatic car wash. Utility Model Content

[0004] The purpose of the utility model is to overcome the shortcomings of the existing technology and provide a monorail train automatic car wash control system, which automatically controls the vehicle to be in the state required for car washing when car washing is needed, and further checks whether the vehicle status data before and during car washing meets the car washing requirements. Once it is detected that the car washing requirements are not met, the car wash system can be directly disconnected, thereby improving the reliability of car washing and avoiding damage to monorail vehicles caused by car washing.

[0005] In order to achieve the above-mentioned purpose, the technical solution adopted by the present invention is: an automatic car wash control system for a monorail train, comprising an on-board control unit, a train control unit, a positioning module and a car wash manual trigger module; the car wash manual trigger module is used to record the car wash signal of the operator, and its output end is connected to the on-board control unit; the positioning module is used to collect whether the vehicle is in the car wash station, and its output end is connected to the on-board control unit, and the output end of the on-board control unit is connected to the train control unit, and the train control unit is used to control the train's air conditioning, doors, and wipers to be in a car wash state according to the signal of the on-board control unit.

[0013] The following is a brief description of the contents and symbols in the drawings of the present invention:

[0015] Figure 2This is a schematic diagram of the control system of the monorail vehicle of the present invention. DETAILED DESCRIPTION

[0016] The specific implementation of the present invention will be further explained in detail below by describing the best embodiment with reference to the accompanying drawings.

[0017] This embodiment is mainly to solve the defect in the prior art that monorail trains need to manually close the doors, air conditioner and wipers when performing automatic car washing. When the operation is forgotten or the automatic car washing is not successfully performed, there will be certain car washing risks, which will cause damage to the train during the car washing. In addition, manually closing the doors, air conditioner and wipers is cumbersome and easy to forget. In order to solve the defect, this embodiment provides a system that can be automatically controlled to meet the needs of automatic train washing.

[0018] like Figure 1 、 2 As shown, a monorail train automatic car wash control system includes an onboard control unit, a train control unit, a positioning module and a car wash manual trigger module;

[0019] The car wash manual trigger module is used to record the operator's car wash signal, and its output end is connected to the on-board control unit; the positioning module is used to collect whether the vehicle is in the car wash station, and its output end is connected to the on-board control unit. The output end of the on-board control unit is connected to the train control unit. The train control unit is used to control the train's air conditioning, doors, and wipers to be in the car wash state according to the signal of the on-board control unit.

[0020] Its working principle is: when automatic car washing is required, a manual control signal is sent to the on-board control unit through the car wash manual trigger module. At this time, after the on-board control unit receives the manual control signal, it will forward the car wash control signal to the train control unit. The train control unit controls the shutdown of the air conditioner and the fresh air valve of the air conditioner to prevent water from entering the fresh air valve of the air conditioner. At the same time, it controls the closing of the car door and the control of the wiper to the set position to meet the requirements of car washing; at the same time, the positioning module can detect and confirm whether the vehicle is in the car wash station. When it is detected that the vehicle is in the car wash station, it is also determined that the vehicle needs to be washed. At this time, the on-board control unit automatically sends the corresponding car wash control signal to the train control unit. At this time, the train control unit controls the air conditioner, car doors and wipers.

[0021] The train control unit includes the train TMS, which is used to control the operating status of the vehicle's wipers, doors, and air conditioning. The train TMS is a train automatic control system that can control various devices and electrical appliances within the train. By linking the onboard control unit with the train TMS, the TMS is used to control the status of the doors, wipers, and air conditioning system valves to meet the requirements of car washing. The onboard control unit, serving as the core controller of this embodiment, can be implemented using a microcontroller such as a single-chip microcomputer, or directly integrated into an existing controller within the vehicle, such as the TSM system.

[0022] The manual car wash trigger module includes the VATC system and / or TMS touchscreen. The onboard control unit is connected to the train network and receives control signals from the VATC system and the onboard TMS touchscreen via the train network. The operator's manual car wash control signals can be recorded by the VATC system or the onboard TMS touchscreen and then transmitted to the onboard control unit, enabling the operator to actively control the train to enter car wash mode. The train can be controlled either manually or through automatic positioning monitoring, eliminating risks such as water intrusion during the car wash due to manual forgetfulness. The dual redundancy approach ensures accurate entry into car wash mode and controls the air conditioning, doors, and wipers, preventing the risk of forgetting to close doors or operate the air conditioning or wipers.

[0023] The positioning module primarily detects whether a train is at a car wash station. Since automatic car washes typically occur at specific stations, when a train is located at a car wash station, it automatically sends control commands to the TMS system to control the doors, wipers, and air conditioning to meet wash requirements. The positioning module can employ various methods, including proximity switches at the car wash stations or NFC (near-field communication) recognition.

[0024] In a preferred embodiment, the onboard control unit is connected to a status monitoring unit, which is used to monitor whether the vehicle status data is in a car wash state. The status monitoring unit includes a door opening and closing status monitoring unit, a wiper position status monitoring unit, and an air conditioning operation status monitoring unit, which are used to monitor the status of the door, wiper, and air conditioner respectively. The door opening and closing status monitoring unit, the wiper position status monitoring unit, and the air conditioning operation status monitoring unit are used to monitor whether the door is closed, whether the air conditioning fresh air valve is closed, and whether the wiper is in a vertical position respectively. If any of the monitoring results is negative, it means that the train does not meet the car wash conditions and the control signal sent by the train TMS is not accurately executed. Therefore, the control alarm sends an alarm signal at this time, that is, the output end of the onboard control unit is connected to the alarm to send a warning signal of abnormal washing state, reminding the operator that the train status at this time does not meet the requirements of the car wash mode, thereby avoiding safety risks and damage to the vehicle caused by the car wash at this time.

[0025] Furthermore, the onboard control unit is connected to the train car washing device via wireless communication, and is used to send car washing start and emergency stop signals to the train car washing device; the train car washing device operates according to the received emergency stop or start signals. If the car washing has already started or is detected after washing, such as the car door is not closed, the air conditioning fresh air valve is not closed, or the wipers are not in the vertical position, then the car washing device needs to be stopped in time. A control signal can be sent to the control system of the train washing device via wireless communication to initiate an emergency stop, thereby achieving the purpose of emergency stop of the car washing and avoiding the risk of washing the car when the train status does not meet the washing requirements.

[0026] When the train exits operation and returns to the depot and automatically enters the car wash area, the car wash command can be manually sent to the TMS through the VATC through the train network, or the car wash command can be issued through the TMS touch screen or through work station detection. After the car wash command reaches the TMS system, the TMS triggers the closure of all the air conditioning fresh air valves of the train, and the air conditioning enters the car wash mode; at the same time, the wiper arms at both ends of the train are controlled to the center and all doors are controlled to close; the train will complete the above actions within 5 minutes, and the TMS collects the operating status of the air conditioning and wiper equipment, and the status of the doors. When the conditions for car washing are met, the information that the car can be washed can be fed back through the alarm, reminder or even the VATC system. At this time, the train car wash state can be started to clean the train. When the monitoring shows that the operating status of the air conditioning and wiper equipment and the door status do not meet the car washing conditions, an emergency stop command needs to be issued to the car wash device to stop the car wash.

[0027] This solution improves the efficiency of the car washing process. Manual control of the air conditioner, doors, and wipers is no longer required, and automatic control is also possible. Secondly, the entire car washing process is automated. There is no need for human intervention to operate train-related equipment such as air conditioners and wipers to enter the car washing state. Control can be performed automatically with one click or automatic recognition, which greatly shortens the car washing time and improves the operation process of the monorail train.

[0028] Obviously, the specific implementation of the present invention is not limited to the above-mentioned methods. As long as various non-substantial improvements are made using the method concept and technical solution of the present invention, they are all within the scope of protection of the present invention.
