Description

Technical Field

[0001] The present invention belongs to the field of new generation information technology, and in particular relates to a circuit control method and system for a DC gas water heater dedicated to a recreational vehicle. Background Art

[0002] Since vehicles such as RVs have limited cargo capacity and their energy supply cannot be achieved stably in the long term, the energy supply of RVs, especially the design and guarantee of temperature control and hot water supply, has always been one of the problems that need to be solved urgently in self-driving travel.

[0003] Generally speaking, RVs are often defined as special vehicles that have both mobility and living functions. Their core technology lies in the organic combination of highly integrated living space design and vehicle power systems. Structurally, RVs are based on automobile chassis and use high-strength lightweight materials to build the body frame. Precision welding and riveting technology are used to ensure the stability and durability of the body structure. The interior space is cleverly laid out, using foldable and retractable furniture designs, such as hidden beds and retractable dining tables, to achieve flexible transformation and efficient use of space. At the same time, RVs are equipped with advanced water and electricity systems, including large-capacity clean water tanks, sewage tanks, and efficient water pumps to ensure the supply of domestic water and the reasonable discharge of wastewater; the power system integrates on-board generators, solar panels, and large-capacity batteries to form a multi-energy complementary power supply mode to meet the power needs of electrical equipment in the car. In addition, RVs are also equipped with intelligent navigation and driving assistance systems, such as high-precision GPS positioning, reversing images, lane departure warnings, etc., to improve driving safety and driving convenience, making RVs a mobile and comfortable living space, providing all-round life guarantees for outdoor travel and long-term residence.

[0004] RV gas water heater is an efficient hot water supply device designed for RV environment. Its core lies in the precise integration of gas combustion technology and compact heat exchange system. The device adopts miniaturized gas burner and uses advanced air-gas mixing technology to ensure full combustion of gas, with a combustion efficiency of more than 80%, so as to efficiently convert chemical energy into thermal energy. The high-temperature flue gas generated by combustion exchanges heat with the cold water flowing through it through a precisely designed heat exchanger. The heat exchanger is made of stainless steel with high thermal conductivity. The spiral water flow channel design inside it makes the water fully disturbed during the heating process, significantly improves the heat exchange efficiency, and makes the water temperature rise rapidly. In terms of safety protection, the RV gas water heater is equipped with a gas leak detection sensor and an automatic flameout protection device. Once a gas leak is detected or the flame is accidentally extinguished, the system will immediately cut off the gas supply and send out an audible and visual alarm through the built-in alarm module to ensure the safety of people in the RV. At the same time, its intelligent control system can be seamlessly connected with the central control system of the RV, and some have fault self-diagnosis and real-time status feedback functions, providing RV users with convenient, safe and efficient hot water solutions.

[0005] The DC circuit and energy exchange control of RVs are often separated, and the integrated performance of electric energy management and water heater energy management and display management is not strong. There are deficiencies in informatization and networking. Many relevant control information cannot be known and used by users, resulting in low energy utilization efficiency of RVs and insufficient intelligent utilization of equipment by the driver.

[0006] The present invention proposes a DC gas water heater circuit control method and system for RVs. Based on the energy supply and heat exchange mode of RVs, a differentiated RV DC power network is provided for controlling the DC power supply and use of RVs; a RV-specific water heater energy drive CAN node control network module is used to execute water heater energy drive control; and a RV-specific Internet of Things network module is used to execute the Internet of Things connection in the RV to realize gas water heater circuit control. By setting up three different subnets, the power network dedicated network management is realized, and the configuration and management of water heater energy data are realized by collecting energy drive network data and integrating with the CAN network. At the same time, the RV-specific Internet of Things network is used to connect the RV DC power network and the energy drive network, realizing the integration of power data, energy data and Internet of Things transmission information, providing data support and security for DC gas water heater circuit control, thereby improving the RV-specific DC gas water heater circuit configuration and management capabilities, and further networking the information interaction and water and electricity energy control architecture of RV-specific DC gas water heaters.
