The invention discloses an automatic fertilization flowerpot with the fertilizer mixing function. The automatic fertilization flowerpot comprises a pot body, wherein a planting cavity with an upward opening is formed in the middle of the interior of the pot body, and a mixed fertilization mechanism for mixing two kinds of fertilizers and applying the fertilizers into soil is arranged on the side wall of the upper end of the planting cavity; and a floor capable of moving up and down and used for bearing plants is arranged at the bottom of the flowerpot, when too much water is accumulated in the flowerpot, the water can be automatically drained through the drainage function of the floor, the root rotting phenomenon is prevented in time, and when the plants need to be transplanted, a bottom plate can be moved upwards to integrally transplant the plants. The plant transplanting convenience can be greatly improved. When the plants need to be subjected to mixed fertilization, the two kinds of fertilizers are automatically discharged and stirred through the fertilization mechanism, the mixed fertilizers are automatically and comprehensively applied into the soil after stirring is completed, the function of completing automatic mixed fertilization by means of the flowerpot is achieved, and the functional diversification of potted plants is greatly increased.

The invention relates to a regular hexagon solar heat collecting tube and an application method, belonging to the solar energy application field. The heat collecting tube is made by plastic particles under certain process conditions, and has a regular hexagon appearance with plane outer lateral surfaces and concave inner lateral surfaces as well as certain shock-resistance physical index. The heat collecting tube has the advantages of high heat collecting efficiency, little heat reflection, long service life and aging resistance, and meets outdoor application conditions. Copper heat pipes are installed in the heat collecting tubes with different thicknesses and widths; the heat collecting tubes are sealed and vacuumized or keep constant pressure; sunlight converges on the concave parts of the inner sides of the tubes and then directly gathers on the copper heat pipes; water does not go through the regular hexagon solar heat collecting tube; heat is transferred through heat pipes to heat a water collecting system; all pipes can be combined horizontally or randomly combined on the six surfaces; and the heat collecting tubes are welded for fixation by a plastic welder or shaped in anchor ear connection. The heat collecting tubes are connected to a heat exchange and water collection system and a water storage system to form a solar collector, and can be integrally installed on a wall, a roof and a balcony, and outside or inside a window.

The invention provides a wireless communication method based on the IEEE802-15-4 standard. The method requires a coordinator having the wireless communication capability based on the IEEE802-15-4 standard and a plurality of terminals having the wireless communication capability based on the IEEE802-15-4 standard, the coordinator and the terminals forming a local area network. The coordinator is provided with a periodic timer. After connection is established between the terminals and the coordinator, a counter is established for each terminal device in connection; after the timing of a period is over, one is added to the counters corresponding to all the terminal devices in connection; each terminal sends a heartbeat packet to the coordinator at intervals to report the connection state; users start wireless voice talkback through buttons and the coordinator can directly initiate voice talkback; other terminal devices need to send request information to the coordinator and cannot initiate voice talkback until the coordinator replies to and confirms the requests. Compared with the conventional methods, the method has the advantages of multiple functions, small size and low power consumption.
