Recently, the intelligent sorting robot “Little Orange Man†independently developed by Haikang Robotics has quickly become popular. Although this "Little Orange Man" looks petite and sleek, but the saying goes, "The sparrow is small and complete," through its intelligent robot sorting system, 300 "Little Orange Man" can sort 20,000 pieces per hour. package. Indeed, in recent years, the application of robots in the field of logistics has become increasingly deep, and a wave of “artificial intelligence + logistics†has been launched on a global scale. On March 3 this year, the governor of Virginia, USA, signed a bill allowing robots to send couriers, which will take effect on July 1. According to the Act, the courier company can use the robots that do not exceed 10 miles per hour to deliver the courier from July 1 this year. The delivery is no more than 50 pounds (about 22.6 kg). In addition, according to the BBC news on April 17, Hermes Express announced that it began testing automated receiving robots on the streets of London. The autonomous driving robot was developed by Estonian delivery robot company Starship Technologies, which is mainly used to collect parcels. In some parts of London, Just Eat, the UK's largest takeaway provider, has used the robot to deliver food. The delivery robot is 55 cm high, 70 cm long, weighs 18 kg and has a speed of 6.4 km/h. In addition to robots, drones are also a good helper in the logistics industry. As the founder of the express drone, Amazon first began testing the drone delivery. After several system upgrades, the Amazon drone had a "brain" and sent the courier to be smarter. For this upgrade, Amazon has invested heavily in the acquisition of a European computer vision team based in Graz, Austria. The members are all elites in computer vision. After Amazon’s demise, their main task is for the Amazon. The machine is equipped with a "brain" to overcome visual obstacles and deliver accurately. On the other hand, domestically, on the one hand, in terms of policy, promoting technological innovation has become an important task for the development of the express delivery industry. The 13th Five-Year Plan for the Development of Express Industry issued by the State Post Bureau clearly stated that it encourages express delivery companies to adopt advanced and applicable technologies and equipment to promote the development and application of robots, drones and unmanned vehicles. On the other hand, a number of courier companies began to deploy unmanned vehicles and drones in the logistics field. Take SF as an example. In 2013, SF has begun testing drones to deliver packages. According to the SF Annual Report, as of February 2017, SF Holdings reported and obtained 111 patents in the field of drones. In addition, Jingdong UAV has also been put into operation in Beijing, Xi'an and other places. It is reported that as of November 2016, Jingdong UAV has completed more than 10,000 minutes of flight duration, nearly 10,000 kilometers of flight mileage, and more than 1,000 flights. In the current smart logistics industry, robots and drones are rare and capable. The robot travels steadily and has many advantages over airborne drones, such as being able to carry heavier loads and easier control of the route. However, ground robots will be closely monitored by operators. Take the Starship ground robot as an example. Each operator will supervise three robots through the onboard camera to control them crossing the road or other challenging situations. Starship said that each operator should be able to control up to 100 robots, which will greatly improve the operating cost performance. From this point of view, both the express robot and the delivery drone have their own advantages, and there are also deficiencies. How to choose depends on the diversified market demand. Alarm release mainly uses standard equipment such as audio alarms. During wartime, communication, broadcasting, and television systems must prioritize the transmission and issuance of air defense alarm signals, and auxiliary means such as sirens, horns, and gongs can also be used. The sound alarm must be set at the designated location, and the alarm facilities must be maintained in good working condition. The release and transmission of alarms should be fast and accurate, and multiple means should be used simultaneously; Strengthen communication and liaison with superiors, subordinates, and neighbors, receive air raid intelligence information at any time, strengthen observation of air targets, and promptly report air raid intelligence; According to the situation and duration of the air raid, timely release the warning signal. With the sudden increase of air raids, the increase of attack methods, and the expansion of destruction, the importance of air defense alerts is increasingly being valued. The accuracy, timeliness, and continuous issuance ability of air defense alerts are required to be higher. The issuance methods of air defense alerts will also become more flexible and diverse with the construction and improvement of communication and network.
