Detailed Description
The following explains the monitoring circuit for pesticide spraying in agriculture and forestry provided by the invention with reference to the accompanying drawings.
Fig. 1 is a schematic circuit diagram of an agriculture and forestry monitoring circuit for spraying pesticide, and referring to fig. 1, the invention provides an agriculture and forestry monitoring circuit for spraying pesticide, which includes: the device comprises a spray switch 1, a relay 2, an electromagnetic valve 3, a low liquid level sensor 4, an indicator lamp 5, a high-definition camera 6, a display 7 and a circuit breaker 8; wherein,
the spraying switch 1 is a single-pole single-throw switch, one end of the spraying switch is connected with a direct-current power supply through a breaker 8, and the other end of the spraying switch is connected with the electromagnetic valve 3 through a relay 2 to supply power to the electromagnetic valve 3; a relay 2 and a low liquid level sensor 4.
The low liquid level sensor 4 is arranged at the bottom of the medicine chest and is connected with the relay 2; when the chemical liquid level is low, the output terminal outputs 28V to the coil of the relay 2. When the liquid level is high, the output end does not output.
The indicator light 5 is mounted on the dashboard and provides a warning signal of attention level.
The camera 6 is arranged on the transparent observation window of the medicine box and can shoot a scale picture of the medicine liquid in real time. The display 7 is mounted on the instrument panel, the display 7 is interconnected with the camera 6, and the picture sent by the camera 6 is received through a high-definition data line, such as an HDMI (high-definition multimedia interface) line, so that the pilot can observe the amount of the liquid medicine.
