    Abstract: A shelf label communication method based on a synchronous network, a shelf label system and a computer device are provided. The synchronous network includes a base station topological structure, including a master base station, a first-level secondary base station directly connected to the master base station, and a (i+1)th-level secondary base station directly connected to an ith-level secondary base station, and each base station being connected to only one superior base station. The first-level secondary base station obtains a first synchronization signal from the master base station, so the first-level secondary base station starts to operate according to system time of the master base station. Further, the (i+1)th-level secondary base station obtains a second synchronization signal from the ith-level secondary base station, so that the (i+1)th-level secondary base station starts to operate according to local system time of the ith-level secondary base station.

  • Patent number: 12015378
    Abstract: A hybrid receiver for a concentrator photovoltaic-thermal power system combines a concentrator photovoltaic (CPV) module and a thermal module that converts concentrated sunlight into electrical energy and thermal heat. Heat transfer fluid flowing through a cooling block removes waste heat generated by photovoltaic cells in the CPV module. The heat transfer fluid then flows through a helical tube illuminated by sunlight that misses the CPV module. Only one fluid system is used to both remove the photovoltaic-cell waste heat and capture high-temperature thermal energy from sunlight. Fluid leaving the hybrid receiver can have a temperature greater than 200° C., and therefore may be used as a source of process heat for a variety of commercial and industrial applications. The hybrid receiver can maintain the photovoltaic cells at temperatures below 110° C. while achieving overall energy conversion efficiencies exceeding 80%.
