The invention relates to an intelligent irrigation and fertilization control system and control method. The intelligent irrigation and fertilization control system comprises a main control board and a group connected with the main control board and including a liquid level sensor, a soil moisture sensor, a rainfall sensor, a multi-way relay, an infrared remote controller, a network server and a power supply module for supplying power to the whole system. The intelligent irrigation and fertilization control system further comprises a solenoid valve and an agitator connected with the multi-way relay. The main control board comprises a controller unit and a group connected with the controller unit and including a clock circuit, a GPRS module, an infrared receiving module, a display module, a relay driving circuit, a human body infrared alarm module, and a sound alarm module. The infrared receiving module is used for receiving the infrared control signal of the infrared remote controller. A relay driving circuit is connected with the multi-way relay. A user can obtain and manage the information of the system by getting access to the network server through the network by using a cell phone or an Internet client, wherein the information includes time information, environmental information, equipment state information and control information. The intelligent irrigation and fertilization control system is simple and easy to realize, and achieves remote intelligent irrigation and fertilization and the specific irrigation and fertilization information through the network.

The invention discloses a substation infrared detection method and system. An infrared temperature measurement instrument collects an infrared temperature measurement image in the preset same image acquisition area by presetting the same detection parameter. The infrared temperature measurement instrument carries out collecting at a field preset standard temperature measurement coordinate point of a substation. According to the infrared temperature measurement image, whether the substation has a heating defect is detected. According to the invention, the temperature is detected at the same temperature measurement coordinate to realize fixed point detection; the infrared temperature measurement instrument generates a reference image from a standard image through a diagnostic rule setting system, so as to calibrate an image collecting area and realize the purpose of image fixing; in addition, the same detection parameter is used for repeated detection, so as to realize calibration; the infrared detection of the substation is more standard; the infrared detection workload of operation and maintenance staff is reduced; the infrared detection quality is improved; the equipment state is enhanced; and missed infrared detection is avoided.
