Description

IoT control system and operation method capable of remote automatic and manual operation {IoT control system and operation method capable of remote automatic and manual operation}

The present invention relates to an IoT control system that can control multiple facilities in remote automatic or manual mode. In particular, the IoT controller that constitutes the IoT control system is configured with automatic mode and manual mode, which are redundant backup facilities, and can be controlled remotely. The system can be controlled in automatic mode through computers, smartphones, and mobile apps. When the automatic mode system malfunctions or manual operation is required, the user can conveniently control IoT by switching to manual mode through the manual operation system. It is about an IoT control system and operation method that allows remote automatic and manual operation to use the system.

Recently, as the number of people enjoying camping, one of the leisure activities, has increased, the use of camping cars along with traditional camping tools is also increasing. A camping car is a special vehicle equipped with traditional camping tools such as a tent, cooking and cooking utensils, etc., and multiple facilities installed in the camping car are manually controlled through a control panel. Multiple facilities include batteries, boilers, fresh water tanks, wastewater tanks, lighting devices, refrigerators, boilers, ventilators, and TVs used to operate the facilities.

Conventional camping cars are equipped with a control panel used to control a plurality of these facilities. The control panel is designed to selectively control each function as well as whether or not to supply power to multiple facilities.

Recently, a motor home integrated control system that combines Internet of Things (IoT) and ICT (Information and Communication Technologies) technologies has been introduced and used. The integrated control system allows you to easily operate the facilities/devices inside the camping car through the touch screen on the control panel, and also checks the remaining amount of fresh water, sewage, and battery on the screen, so it has the advantage of being easier to control and monitor than the existing analog method. there is. Additionally, if the controller is connected to the Internet through IoT technology, you can check the status of the vehicle and remotely control internal facilities at any time from outside using a cell phone or mobile app. This remote control function prevents theft, battery discharge, and freeze prevention, and has the advantage of creating a comfortable indoor environment by turning on the air conditioner or boiler before camping.

Figure 1 illustrates an example of an integrated controller currently available on the market.

Figure 1a illustrates the parallel input/output method and Figure 1b illustrates the communication module method.

Referring to Figure 1a, the parallel input/output method has the advantage of quick response to instructions and convenient inspection when an error occurs, because signals for controlling the power of devices and facilities are output in parallel from the integrated controller as individual signals, but parallel processing is difficult. The disadvantage is that there are a lot of cables.

Referring to Figure 1b, in the communication module method, the relay control unit for controlling the power of devices and facilities receives control commands through communication with the integrated controller, and only 2 to 3 strands of communication cable are required from the integrated controller to the relay control unit. Therefore, it is advantageous in terms of weight reduction, but it has the disadvantage of slow response speed compared to the parallel input/output method and inconvenient inspection when a failure occurs.

The two conventional methods shown in Figure 1 provide the advantage of integrated control through a touch screen, but have the fatal problem that almost all facilities inside the camping car cannot be used when the integrated controller fails. When a camping car's integrated control system breaks down, you must visit a camping car manufacturer or A/S dealer to resolve the problem. Unlike general vehicles, camping car manufacturers and A/S dealers are very rare and there is a limit to receiving immediate service.
