Detailed Description
An embodiment of the automated wireless relay management and control method of the present invention will be described in detail below.
Air conditioners (Air conditioners) are Air conditioners. The device is used for manually adjusting and controlling parameters such as temperature, humidity, cleanliness, flow velocity and the like of ambient air in the building/structure.
Generally comprises a cold source/heat source device, a cold and hot medium delivery and distribution system, a terminal device and other auxiliary devices. The system mainly comprises a refrigeration host, a water pump, a fan and a pipeline system. The end device is responsible for specifically processing the air state by utilizing the cold and heat quantity from the transmission and distribution so as to enable the air parameters of the target environment to meet the requirements.
The first air conditioners and refrigerators used toxic gases such as ammonia and methyl chloride. Such gas leakage can cause serious accidents. Tomas miuli invented chlorofluorocarbon gas (chlorofluorocarbonans) in 1928 and named it as freon. Such refrigerants are much safer for humans, but are harmful to the atmospheric ozone layer. Freon is a trademark of dupont CFC, HCFC or HFC refrigerants, wherein each refrigerant name also includes a number to indicate the molecular composition of its components (e.g., R-11, R-12, R-22, R-134). Among them, the R-22HCFC refrigerant, which is most widely used in the field of direct evaporative type moderate cooling products, will be stopped in equipment for new production in 2010 and completely stopped in 2020. R-11 and R-12 have been taken off-stream in the United states. As an alternative, some refrigerants harmless to the ozone layer have been put into use, including refrigerant R-410A under the trade name "Puron". The novel environment-friendly refrigerants of R290 and R32 gradually come to the market, the R290 only contains carbon and hydrogen in molecules, chlorine and fluorine are not contained, and the Ozone Damage Potential (ODP) is zero.
At present, when multiple air conditioners of the same manufacturer exist in the same room, a user presses a remote controller key once to possibly trigger the same action of the multiple air conditioners, and actually the user may want the nearest air conditioner to execute the action, but the automatic selection mechanism is not involved in various wireless remote control mechanisms at present.
In order to overcome the defects, the invention builds an automatic wireless relay management and control method, which comprises the step of using an automatic wireless relay management and control device to take the air-conditioning equipment closest to a remote controller as target equipment of a remote control signal sent by the remote controller based on the distance comparison result between the remote controller in a room and each air-conditioning equipment.

In addition, dram (dynamic Random Access memory), which is a dynamic Random Access memory, is the most common system memory. DRAM can hold data only for a short time. To retain data, DRAM uses capacitive storage, so must be refreshed (refresh) once at intervals, and if the memory cells are not refreshed, the stored information is lost. (shutdown will lose data). Dynamic RAM is also comprised of a number of basic memory cells multiplexed by row and column address pins.
The structure of the DRAM is simple and efficient, and each bit only needs one transistor and one capacitor. However, the capacitance inevitably has leakage phenomenon, which causes data error if the charge is insufficient, and therefore, the capacitance must be periodically refreshed (precharged), which is also a big feature of the DRAM. Moreover, the charging and discharging of the capacitor requires a process, and the refresh frequency cannot be raised infinitely (frequency barrier), which results in that the frequency of the DRAM can easily reach the upper limit, and even if the advanced process is supported, the effect is very small. With the advancement of technology and the desire of people to overclock, these frequency barriers are being solved slowly.
