The present disclosure relate to a controller system and method for use in storage-style water heating systems that offers significant opportunities for energy saving. The controller system can adjust the water heating system in response to energy demand patterns of user fixtures. The controller system can detect quantity of heated water usage and produce a heated water usage profile. The controller system can determine the quantity or volume of the used heated water without a mechanical flow meter. The controller system can include a cost-effective, accurate, and easy-to-install water temperature sensors that provide measurements of the differentials between water temperatures without direct contact with the water. The water temperature sensors can be cost-effective and easy-to-install sensors that are attached to the water pipes through a strap or other attachment methods.

The invention relates to an Internet of things node and a miniaturization integration method thereof. The Internet of things node consists of five efficient solar cells, one polymer lithium ion battery, one main control circuit board, one wireless transmission circuit and various sensors, wherein the main control circuit, the polymer lithium ion battery and the wireless transmission circuit are stacked and interconnected in an MCM (Multi Chip Module) encapsulating way; each layer is connected with an adjacent layer through a double-row 50-foot pin header 2*50; and four surrounding solar cells are connected in parallel with one solar cell covered on the top, a lithium battery is charged during the day, and power is supplied to the wireless transmission circuit through the lithium ion battery at night, so that long service life of the node is ensured. The Internet of things node is characterized in that: 1, the size is only 18 cm<3>, and the volume power density is up to 20.5Wh / l; 2, the service life of the Internet of things node is long, and the Internet of things node can continuously work normally for 28 days on cloudy days according to calculation of once data transmission per hour; 3, the power consumption of the main control circuit is low, the working current is 24muA, and the static current is lower than 1muA; and 4, the non-shielded transmission distance is 700 meters. A new thought is provided for future throwing type miniaturized Internet of things.

A direct current charging pile charging method based on the module maximum current output and alternate rest comprises: and calculating the module maximum output current Imax in the required voltage according to the constant power curve of a single charging module, wherein the charging module number required being put into Num=IBCL / Imax, the minimum module communication address in the work modules is recorded through the charging pile, and the charging piles of the other modules stops work for rest. According to the algorithm mentioned above, the modules put into work starts from the next address recorded at the last time when the next charging is started. The direct current charging pile charging method based on the module maximum current output and alternate rest can reduce the standby loss of the charging piles, improve the operation efficiency of the charging piles and reduce the waste of electric power and the cost of users. Less harmonic wave and improved power factors can reduce the pollution in the electric energy, and the module alternate rest improves the service life of the modules and reduces the maintenance cost.

The present invention provides a display control system and a display screen. The system includes: a sending card, a processing module, a switch module, and a display assembly; the display assembly includes at least one of a receiving card, an adapter card, and a display module; The control end of the switch module is connected to the sending card, the first end of the switch module is used to connect to the power supply, and the second end of the switch module is connected to at least one of the receiving card, the adapter card and the display module; The processing module sends the SDI signal; through the processing module, the SDI signal output by the sending card is detected to determine whether the display component is working. In the open state, at least one of the receiving card, the adapter card and the display module is disconnected from the power supply, and there is no need for user operation to cut off the power, which can reduce the standby power consumption of the display screen and save electric energy.
