With the expansion of land circulation and the advancement of modern agricultural practices, "plant protection drone flight defense service" has become a key focus in the field of agricultural pest control. But how can we implement this service in a scientific and efficient manner? How do we ensure both work efficiency and effectiveness? Hejian City Mengtianfei Agricultural Service Co., Ltd. is here to provide detailed insights and answers.
Before starting any flight defense operations, it's essential to first define the specific tasks at hand. This includes identifying the type of crops, the area to be treated, the terrain, the types of pests and diseases present, the treatment cycle, the kind of pesticide to be used, and any special requirements from farmers.
To begin with, we assess whether the terrain is suitable for drone flights. We measure the working area and identify regions that may not be safe for spraying due to potential risks. Communication with local farmers is crucial to understand the current state of pests and diseases and to determine the exact prevention and control plan. Farmers may bring their own pesticides, or the team might use pre-prepared ones.
It’s important to note that many farmers use powdered pesticides, which require a lot of water for dilution. However, plant protection drones are designed to save up to 90% of water, making it difficult to properly mix these powders. This could lead to clogging in the spraying system, reducing efficiency and effectiveness. Therefore, it's recommended to communicate with farmers in advance and encourage the use of liquid, suspension, or emulsifiable concentrate pesticides instead.
Additionally, the operational efficiency of plant protection drones varies depending on the terrain, typically ranging between 200 to 600 mu per day. To maximize productivity, it’s essential to prepare sufficient quantities of the right pesticide in advance or have the flight defense team carry specialized formulations.
Next, determining the right flight defense team is crucial. Based on crop type, area size, terrain, pest conditions, and the drone’s operational capacity, the number of operators, drones, and transport vehicles must be decided. Since most crops have a limited window for effective treatment, timely execution is vital. The priority is ensuring the effectiveness of the operation, followed by improving efficiency.
Considering the unpredictable nature of weather and potential technical issues, it’s common to operate with a “2 fly, 1 standby†principle to maintain high efficiency throughout the process.
Weather conditions play a major role in the success of any drone operation. Before starting, check the temperature and wind speed—strong winds or rain can cause significant disruptions. It's also important to plan ahead for power supply needs: electric multi-rotor drones require multiple batteries (typically 5–10), along with chargers and possibly backup generators. For oil-powered helicopters, fuel planning is essential, including securing necessary permits for bulk gasoline if required.
Other preparations include setting up pesticide containers, walkie-talkies for communication, and protective gear like goggles, masks, and overalls. If the service involves using the farmer’s own medicine, the team must verify the type and quantity of pesticide to ensure it matches the required application.
Once everything is ready and the weather is favorable, the team can proceed with the mission. Upon arrival, they should familiarize themselves with the terrain, check for obstacles, and plan the flight path and landing points.
Pesticide preparation usually takes half a day to a full day before the actual operation. Each drone is then checked for functionality, including testing the walkie-talkie frequency and spray system. Once all systems are confirmed, the pilot begins the spraying operation.
Safety is a top priority during the flight. Maintaining a safe distance from people and obstacles is critical. Operators must avoid flying near crowds and ensure assistants and personnel stay clear of the working area. Any malfunction or accident can pose serious risks.
When applying pesticides, it's best to use high-efficiency, low-toxicity products to minimize environmental impact. Spraying should be avoided when temperatures exceed 35°C, as high heat can reduce the effectiveness of the treatment.
At the end of each day, the team records the last spraying location for continuity the next day. They also clean and maintain the drone, check material consumption, and document daily output to ensure consistency and prepare for the following day’s work.
In conclusion, the process of plant protection drone flight defense involves careful planning, precise execution, and strict safety measures. Hejian City Mengtianfei Agricultural Service Co., Ltd. is committed to delivering efficient and effective solutions for modern agriculture.
Encoding Disk
Encoding disk refers to a digital encoder that measures angular displacement. It has the advantages of strong resolving power, high measurement accuracy and reliable work. It is one of the most commonly used displacement sensors for measuring the position of the shaft rotation angle. The code disk is divided into two types: absolute encoder and incremental encoder. The former can directly give the digital code corresponding to the angular position; the latter uses a computing system to make the pulse increment generated by the rotating code disc against a certain reference number addition and subtraction. The metal encoding disk is directly engraved with through and unconnected lines, and it is not fragile, but because the metal is not easy to corrode but easy deform, the accuracy is limited, and its thermal stability is an order of magnitude worse than that of glass. It is mainly used in motor, hardware, electrical appliances, automobile and other fields.
We customize diverse patterns metal encoder disk with drawings provided by customers. We are equipped with professional metal etching equipment and exposure development equipment. The raw material use for encoder disk are SUS304 stainless steel and the flat degree can below 0.02 mm. Our stainless-steel encoder disk can achieve flat, no burr and can be available in harsh environment.
