Description

Technical Field

[0001] This utility model relates to the field of vehicle power supply technology, specifically to a garage power supply system for linkage with vehicles. Background Technology

[0002] With the increasing number of modified vehicles, providing them with a safe and convenient parking and power supply environment has become an urgent problem to be solved. Traditional modified vehicles usually lack dedicated garage facilities, and long-term outdoor parking exposes them to harsh weather conditions, easily leading to vehicle wear and tear or performance degradation. Therefore, modified vehicles need to be parked indoors most of the time. However, existing indoor parking methods lack dedicated garage facilities, leaving vehicles often in an exposed state, inconvenient charging, and posing certain safety hazards.

[0003] Current charging methods typically involve drawing power from nearby sources, which has several drawbacks. First, the charging process cannot be automated, making it difficult to guarantee that the charging equipment will automatically trip and cut off the power supply in case of abnormal situations (such as current overload or short circuit). This not only increases the safety risks during vehicle charging but may also lead to short circuits, posing a potential safety threat to the vehicle and the garage environment.

[0004] Therefore, there is an urgent need for an intelligent garage power supply system that can be linked with the vehicle to address the power supply problem in garages for traditional modified vehicles. Utility Model Content

[0029] Furthermore, the terms “comprising,” “having,” and any variations thereof are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units that are expressly listed, but may also include other steps or units that are not expressly listed but are inherent to these processes, methods, products, or devices, or steps or units added based on further optimizations of the inventive concept.

[0030] like Figures 1 to 4 As shown, a garage power supply system for linkage with a vehicle includes a garage, a mains power supply device and a controllable power supply device installed in the garage, and a power supply.

[0031] The power supply is a 220V AC power supply. The output terminal of the power supply is connected to the input terminal of the main relay. The first output terminal of the main relay is connected to the power supply terminal of the mains power supply equipment. The second output terminal of the main relay is connected to the input terminals of multiple branch relays. The output terminals of the branch relays are connected to the power supply terminal of the controllable power supply equipment through contactors.

[0032] The coils of the main relay, the branch relays, and the contactor are all controlled by a programmable logic controller (PLC), which is connected to a host computer.

[0033] The mains power supply equipment includes monitoring equipment and network equipment in the garage;

[0034] The controllable power supply equipment includes garage roller shutters, lighting equipment, ventilation equipment, and vehicle charging equipment in the garage.

[0035] It should be noted that the garage power supply system for vehicle linkage provided by this utility model includes power supply sections for garage roller shutters, lighting, ventilation, monitoring equipment, network equipment, and vehicle charging. Powering on each component is controlled by a host computer, which sends control actions to a PLC via network communication. The PLC output is connected to the coils of each branch relay or contactor, enabling remote control of the power supply to each device.

[0036] This application designs a garage and its power supply system based on a modified vehicle. A suitable-sized shipping container was selected and converted into a garage according to the vehicle's dimensions and required driving space. The design includes key components such as environmental control, roller shutter doors, lighting, ventilation, monitoring, communication, and charging. Monitoring and communication are continuously in active or standby mode, while other components are independently powered and remotely controlled. Power cables are routed through an opening at the bottom of the garage into the cabinet, passing through a main circuit breaker to individual branch circuit breakers. Contactor main contacts are connected below the circuit breakers, then to the respective electrical devices. Relays and contactor coils are controlled by the PLC output. The normally open auxiliary contacts of each contactor, the normally open contacts of the relays, and the roller shutter door's on / off signal are connected to the PLC input, providing status feedback for the program. A host computer within the vehicle connects wirelessly to the garage's local area network, exchanging data with the PLC, issuing power on / off commands for various components, controlling the roller shutter door's opening and closing, reading environmental control feedback data (temperature and humidity), and setting heating, cooling, and dehumidification parameters for the environmental control equipment (air conditioning).

[0037] In the garage, power is supplied via a cable run through the floor, connected to the power input terminal, and then routed out to the top of the main circuit breaker. The bottom of the main circuit breaker connects to a power supply terminal block, which is branched off using a busbar, with each branch power line connected to its respective circuit breaker. Equipment is grouped according to its usage scenario. Communication and monitoring equipment (such as switches, video recorders, AC adapters, PLCs, etc.) requires continuous operation or standby; these are grouped under direct mains power, connected directly from the power supply terminal at the bottom of the main circuit breaker, ensuring continuous power supply as long as the main circuit breaker is closed. Other equipment (such as air conditioners, roller shutters, charging boxes, audible and visual alarms, etc.) does not require continuous power; these are grouped under controllable power supply, with power supplied from the bottom of the circuit breaker to the top of the main contacts of the corresponding contactor. The bottom of the contactor's main contacts connects to the equipment's power supply terminal, from which a line extends to the equipment's terminal. A 24V supply is drawn from the switching power supply and connected to the top of the normally open contact of a relay. The lower end of the normally open contact of the relay is connected to the coil of the contactor. The positive terminal of the 24V power supply is connected to the common terminal of the PLC output module, and the PLC output point is connected to the positive terminal of the remotely controlled relay coil. The negative terminal of the relay coil is connected in parallel to the negative terminal of the 24V power supply, forming a circuit. When the PLC has an output, the output point is closed, the relay coil is energized and closes, the normally open contact closes, the control contactor coil is energized and closes, the contactor's main contacts close, and the corresponding branch circuit is powered on.

[0038] Although both the contactor coil and the relay coil are 24V, the contactor cannot be forced to operate. If the PLC output point is directly connected to the contactor coil, the branch circuit will not be powered on if the PLC output point malfunctions, making temporary troubleshooting impossible and requiring a significant amount of time. Therefore, a relay adapter is chosen. The relay coil has a mechanical forced switch, which can force the coil to operate when the PLC output point malfunctions, achieving rapid emergency power-on.

[0039] To facilitate remote client reading of the device's current power-on / off status, the normally open contacts of the contactors controlling each branch power supply are connected to the PLC input terminals for status feedback. The positive terminal of the DC power supply is connected to the common terminal of the PLC input module. Each PLC input point is connected to the upper end of the corresponding normally open contact of the contactor, and the lower end of the normally open contact is connected in parallel to the negative terminal of the DC power supply, forming a circuit. When the contactor engages and the device is powered on, the normally open contact closes, the corresponding PLC input point is activated, and power-on feedback is obtained. This status is then fed back to the client via communication.

[0040] The garage is connected to the main control room via a wired connection. The connection method is determined by the distance between the control room and the garage; a network cable is used for shorter distances, and a fiber optic cable for longer distances. The main control room contains a host computer with higher priority than the vehicles. It can control the garage to maintain environmental control and charging functions even when the vehicles are in energy-saving mode. The video recorder can be accessed via the network to view the monitoring footage and observe the garage's real-time status.

[0041] This utility model provides a garage power supply system for vehicle linkage, including a garage, mains power supply equipment and controllable power supply equipment installed in the garage, and a power supply. The power supply is a 220V AC power supply. The output terminal of the power supply is connected to the input terminal of a main relay. The first output terminal of the main relay is connected to the power supply terminal of the mains power supply equipment, and the second output terminal of the main relay is connected to the input terminals of multiple branch relays. The output terminals of the branch relays are connected to the power supply terminal of the controllable power supply equipment through contactors. The coils of the main relay, branch relays, and contactors are all controlled by a programmable logic controller (PLC), which communicates with a host computer. The mains power supply equipment includes monitoring equipment and network equipment in the garage. The controllable power supply equipment includes garage roller shutters, lighting equipment, ventilation equipment, and vehicle charging equipment. By using a 220V AC power supply and utilizing the main relay, branch relays, and contactors for circuit control, the mains power supply equipment and controllable power supply equipment in the garage can achieve safe and stable power supply. The main relay ensures a stable power supply for mains-powered equipment (such as monitoring and network devices), guaranteeing uninterrupted security monitoring and communication functions in the garage. A combination of branch relays and contactors allows for the start-stop control of controllable power supply equipment (such as roller shutters, lighting, ventilation, and vehicle charging equipment) as needed. In particular, the vehicle charging equipment utilizes a programmable logic controller (PLC) for automated control and remote monitoring by a host computer, automatically cutting off power in case of short circuits or other abnormalities, ensuring high safety. This solution effectively addresses the risk of short circuits caused by prolonged vehicle charging without automatic power disconnection, while PLC control enables remote intelligent management, enhancing the safety and convenience of the garage power supply system.

[0042] In one embodiment of this application, the number of branch relays, the number of contactors, and the number of electrical devices in the controllable power supply equipment are equal and correspond one-to-one. The output terminal of the branch relay is connected to the input terminal of its corresponding contactor, and the output terminal of the contactor is connected to the power supply terminal of its corresponding electrical device.

[0043] In one embodiment of this application, the second output terminal of the main relay is connected to the branch relays via a bus, the bus being used to distribute the power from the power supply to the input terminals of the plurality of branch relays.

[0044] In one embodiment of this application, the motor of the garage roller shutter door is connected to the contactor.

[0045] The roller shutter door control box is powered by 220V. The AC power supply terminal is connected to the lower end of the contactor, which controls the power on and off. Its output terminals (one neutral and one live) are directly connected to the roller shutter door motor. The control input terminals are passive inputs; the common terminal is connected out to the upper end of the normally open contact of the relay that controls the stop switch, forming a parallel connection. From the lower end of the normally open contacts of the three stop relays, the connections are made to the corresponding control points on the control box. When the PLC output point is activated, the relay coil is energized and the normally open contact closes, resulting in a signal at the corresponding control box input point, controlling the motor to run and achieving remote control of the roller shutter door.

[0046] In one embodiment of this application, the garage power supply system further includes a limit switch that cooperates with the garage roller shutter door, and the output terminal of the limit switch is connected to the PLC.

[0047] The linkage between the garage and the vehicle primarily involves the control and status feedback of the roller shutter door. The host computer in the vehicle connects to the garage's local area network via wireless communication using the MODBUS TCP protocol, exchanging data with the PLC. When the vehicle is about to leave the garage for work, the host computer sends commands to power on and open the roller shutter door. Upon receiving these commands, the PLC controls the corresponding output points to activate, activating the relevant relays and contactors to power on the roller shutter door control box and open the door. When the roller shutter door is fully open, a limit switch is triggered, and the PLC receives the completion signal, which is then fed back to the host computer. Only after receiving the door completion signal does the host computer control the vehicle to begin moving. For extended operations, after the vehicle leaves the garage and confirms it is not in a position where interference might occur, a command is issued to close the roller shutter door.

[0048] After the vehicle returns from its operation, it first checks the status of the roller shutter door at the garage door. By reading the status of the limit switches corresponding to the input points in the PLC, it determines whether the door is fully open. If it is not fully open, it sends a command to power on the roller shutter door and open it; if it is fully open, it drives directly into the garage. After entering the garage, it stops at the designated position, confirms that it is not in a position that may cause interference, and sends a closing command. The roller shutter door closes, and after it is fully closed, a signal is fed back to the host computer, which determines whether to power down to save energy.

[0049] In one embodiment of this application, the power supply terminals of the lighting equipment and the ventilation equipment are also connected to a wall switch in the garage.

[0050] The garage is equipped with lighting and ventilation systems, using a dual-control system with wall switches and remote control. Taking lighting as an example, a 24V DC power supply line is taken and connected to the upper terminal of the wall switch. The lower terminal of the wall switch is connected to the coil of relay D3KA10. The positive terminal of the DC power supply line is connected to the common terminal of the PLC output module. The PLC output point Q0.6 is connected to the positive terminal of the coil of relay D3KA7, and the negative terminal of the coil of relay D3KA7 is connected back to the negative terminal of the DC power supply line. A 220V AC power supply line is taken and connected to the upper terminal of the circuit breaker D4QF4 for the lighting branch. The lower terminal of the circuit breaker is connected to the common terminal of the contact of relay D3KA10 controlled by the wall switch. The normally open contact of relay D3KA10 controlled by the wall switch is connected to the normally closed contact of relay D3KA7 controlled by the remote control, and vice versa. The common terminal of the remote control relay D3KA7 is connected to the coil of the lighting status feedback relay (this relay coil is AC 220V), and then connected to the lighting lamp. Connect the positive terminal of the DC power supply to the common terminal of the PLC input module. Connect the PLC input point to the upper terminal of the normally open contact of the status feedback relay D3KA12, and connect the lower terminal of the normally open contact of the relay to the negative terminal of the DC power supply, forming a circuit. The wiring method for the exhaust system is the same as for the lighting system, except that the corresponding input / output points and relay numbers in the PLC are different.

[0051] This connection method ensures that the device is not powered when both the wall switch and remote control are on or off, and is powered on only when either the wall switch or remote control is on. This facilitates maintenance by allowing personnel to easily turn on lights when entering the garage, while preventing energy waste caused by leaving lights and ventilation on after operation or maintenance. It also allows for remote status feedback, resolving the issue of remote control only being able to control output but not determine the device's power-on status after dual control.

[0052] In one embodiment of this application, the PLC is connected to the host computer via a wireless communication module, and the wireless communication module uses the MODBUS TCP protocol.

[0053] In one embodiment of this application, the garage power supply system further includes an audible and visual alarm device, which is connected to the PLC.

[0054] The garage roller shutter door is equipped with an audible and visual alarm, which can be set by the user. During vehicle movement or the raising and lowering of the roller shutter door, the PLC output point Q1.0 can be controlled via communication to control whether the audible and visual alarm is powered on and sounds an alarm, thus serving as a warning.

[0055] The embodiments described above merely illustrate specific implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
