Interactive control system for an HVAC system

An interactive system for controlling the operation of an HVAC system is provide that comprises a thermostat for initiating the operation of the HVAC system in either a full capacity mode of operation or at least one reduced capacity mode of operation, and a controller for an outside condenser unit having a condenser fan motor and a compressor motor, the controller being capable of operating the compressor in a full capacity mode and at least one reduced capacity mode. The system also comprises a controller for an indoor blower unit having a blower fan motor, the controller being capable of operating the blower fan motor in a full capacity mode an at least one reduced capacity mode. The system further includes a communication means for transmitting information between the outside condenser unit controller and at least the indoor blower controller, where the information relates to the operation of the indoor blower and the outdoor condenser unit. The indoor blower controller responsively controls the operation of the blower fan motor in a full capacity mode or a reduced capacity mode based on the information received from the outdoor unit controller, and the outdoor unit controller responsively controls the operation of the compressor in a full capacity mode or a reduced capacity mode based on the information received from the indoor blower controller.

Transplanting method of big camphor trees

A transplanting method of big camphor trees comprises selection of the big camphor trees, transplanting, transplanting transportation of trees, planting and planting management. Particularly, the angle of a planting sunny side cannot be deviated by over 10 degrees, root irrigation is performed by using ABT rooting powder, microorganism fertilizer, bactericide liquid chemical and the like which are used in backfill soil according to a fixed proportion, and 1-naphthylacetic acid alcohol water solution of 100-200ppm is used for irrigation after planting of the big camphor trees. The special technical processing of camphor transplanting is that 1-naphthylacetic acid auxin of 0.01-0.03% is added to used mud, the theory of a big wiping head and a big soil ball is adopted, 1-naphthylacetic acid rooting powder is added to the root portions during transplanting, leaves are picked instantly after planting, a blade surface agent is sprayed to new leaves, and originality is provided in the overwintering and antifreezing aspects. By means of the transplanting method, transplanting survival rate of the camphor trees with the tree age below 20 years is over 99%, and transplanting survival rate of the camphor trees with the tree age over 20 years is over 95%. The transplanting method of the big camphor trees can be suitable for transplanting of big trees and old trees under the conditions of other different altitudes, longitudes and latitudes, climate and the like.

Intelligent tree trunk white paining robot

The invention discloses an intelligent tree trunk white painting robot and belongs to the related fields of urban and garden greening equipment. The intelligent tree trunk white painting robot comprises a machine frame system, a robot traveling system, a lime slurry supply system, an automatic white painting execution system and a real-time detection system. Adopting a spray painting mode for white painting of tree trunks, the robot can automatically walk along a side pavement and quickly and efficiently spray lime solution onto trees along the side pavement. In a real-time detection system, a digital compass, a laser sensor and a vision system are adopted to realize the semi-automatic searching of tree trunks and tree trunk automatic positioning, an ultrasonic transducer is adopted to realize automatic obstacle avoidance, and the whole-process real-time monitoring with a personal computer (PC) and a programmable logic controller (PLC) is realized. When the intelligent tree trunk white painting robot is used, coating is saved and the painting effect is optimized; and the robot automatically performs white painting of trees along the side pavement, the working efficiency is improved, labor force is saved, and the goals of intelligent control and green environmental sanitation are fulfilled.
