Is it reliable for UAV to deliver nucleic acid?

Before we start, revise the concept. Accurately speaking, the object of the problem is not "drone", but "drone delivery network". The former is a part of the latter, and the two are not equal.

Question 1: Is it safe?

"There are many advantages of UAV distribution network, which is logically acceptable, but when it is put together with nucleic acid transportation, it always makes people feel uneasy.".

Please note that these are worries, not judgments, emotions and irrationalities. It's natural to worry, but in order to find answers and serve the society, we need to pull away from emotion and establish judgment.

We build a simple analysis model.

The safety problem can be divided into two aspects, one is transportation safety risk, the other is spread infection risk. The method of judgment is very simple, comparison method, compared with the car transportation accepted by the society.

Transportation safety

The delivery network of Antwork has been examined and approved by CAAC, and its operation safety standard is one fatal accident per million flight hours, which is different from that of civil aircraft at the same level. One in a million is the natural death rate of human beings, which is also the safety level accepted by the society.

The number of deaths and accidents caused by ground traffic is far higher than this level. The number of deaths per 10000 vehicles in China's road traffic is 1.80 [0], and the number of motor vehicles in China exceeds 372 million.

Quite simply, a compliant drone delivery network is safer than a car.

Diffuse infection = possibility of leakage * impact size

When the sample package is qualified and intact, the leakage occurs in the external force damage, namely traffic accident. For a drone, it is a crash, which is obviously related to the accident rate. According to the calculation, the drone delivery network crashes are 0.07 to 0.2 times per million kilometers, and the ground traffic accidents are 1.3 times [1], with a difference of one order of magnitude. Of course, accidents don't necessarily mean spills. When the drone parachutes, its impact force is far less than the impact of ground traffic accidents.

It can be seen that the leakage probability of droen transportation accident is far less than that of vehicle.

Once leakage occurs, its impact depends on whether someone contacts it. Due to the special selection of the transportation route of drone delivery network, it can avoid the crowded area, and there is no human contact in the whole process, with real-time positioning and tracking, so the risk is low. Once there is leakage in automobile transportation, the transporters and drivers are the first to bear the brunt, followed by the road crowd.

The above analysis shows that the security of drone delivery network is higher than that of ground vehicle transportation.

Question 2: How many people?

The man-machine ratio of drone delivery network is 0.1-0.25, that is, 0.1-0.25 people are needed for each shift, while 2-3 people are needed for vehicles. Low human dependency provides a foundation for large-scale replication.

Question 3: How fast?

Fast is not high speed, but short time. Jump out of the ground traffic, detour into straight, realize the one-way fast; network scheduling drone resources, response to random demand, and intensive demand, realize the system fast.

As a result, according to the practical evaluation, the overall transportation efficiency of ground transportation has been improved by 50% - 80%, which is really fast.

Even if it is a second fast, it may reduce an infection, and its subsequent chain reaction and social losses.

Even if it's one second fast, it's worth fighting for.

Question 4: is it stable?

It's stable. As mentioned at the beginning, Drone delivery network is a system, including transportation network, drone, ground take-off and landing station, intelligent central control platform, ground support personnel and facilities, etc. The system is different from the single machine, its redundancy level is higher, fleet cooperation, mutual backup. Its operation control does not rely on the pilot (driver), no human factors, extremely stable.

The stability of vehicle transportation depends on vehicle status and driver, while the stability of system level UAV distribution network depends on system, software and program, which has exceeded the stability dimension of single vehicle transportation.

Question 5: is it reliable?

Don't say much. Look at the data. As a civil aviation licensed enterprise, like airlines, Antwork Technology must report any accidents and symptoms. Up to now, the operation mileage of the distribution network has exceeded 100000 km (including 30000 km for medical treatment), and the cumulative accident is 0.

Reliable? Very reliable!

Question 6: is it expensive?

It's fairer than the price. The kilometer cost of drone delivery network is about 50% (oil vehicle) - 100% (TRAM) of vehicle transportation cost under the same transportation mileage. The main cost of drone delivery is battery loss and system operation and maintenance. The main cost of automobile transportation is manpower loss and fuel. The upgrading of technology and the increase of transportation frequency will lead to lower kilometer cost of drone delivery network, while the inevitable increase of manpower can only lead to the increase of automobile transportation cost.

Question 7: Small capacity?

Indeed, the capacity of UAVs can't be compared with that of cars. Be careful not to fall into the logic trap. Load level is not necessarily an advantage, only determines its application scenarios. The advantage is the right load. UAV can transport 200-500 samples at a time, which is higher than or equal to the hourly collection volume of one sampling point. At this point, it's better to "transport away immediately" than to "wait for the bus". For the normalized new crown prevention and control detection system, decentralized collection centralized inspection, smaller quantity and more random is the main demand. Car? It's too expensive.
