An unmanned aerial vehicle article sending method based on an intelligent window comprises the following steps: a user sends an order request to an express operator; the express operator receives the order request of the user, generates an order comprising position information of the intelligent window of the user, and calls an appropriate unmanned aerial vehicle; the unmanned aerial vehicle flies to the intelligent window through positioning, and the intelligent window carries out identity identification on the unmanned aerial vehicle; when identity identification is successful, the intelligent window is opened, and the user sends an article to the unmanned aerial vehicle; and after receiving the article, the unmanned aerial vehicle returns to the express operator or flies to other places to collect articles, and the intelligent window is closed automatically. By utilizing the feature that walls in the house of the user have windows, the house of the user is equipped with the intelligent window; when the unmanned aerial vehicle hovers nearby the intelligent window, the intelligent window carries out identity identification on the unmanned aerial vehicle; and after successful identity identification, the intelligent window can be opened automatically, and the user can send or fetch the articles. The sending / delivering method is simple and reliable, is not limited by time and weather, and allows the user to send or fetch the articles without going out.

An unmanned aerial vehicle delivery system based on smart windows, including a user terminal, a smart window, a drone, and an express operation control terminal. The window at least includes a sensing module 1 and a driving mechanism. The drone is equipped with a sensing module 2. When the sensing module 1 and the sensing module 2 are connected successfully, the driving mechanism of the smart window will open the smart window. When the sensing module 1 and the sensing module 2 are disconnected When the smart window is opened, the driving mechanism of the smart window closes the smart window. The present invention utilizes the feature that there are windows on the walls of the user’s home, and assembles a smart window in the user’s home, so that the UAV can be parked near the smart window, and the smart window can identify the UAV and automatically open it after passing the verification, and the user can Implement shipping or pickup. The mailing and mailing method is simple and reliable, and is not limited by time and weather, so that users can send and receive mail without going out.

The invention discloses an outdoor heating food box which comprises a box body and a box cover, wherein an opening is formed on the upper part of the box body; the box cover is covered on the openingof the box body; a food loading layer and a heating device used for heating the food loading layer are successively arranged on the bottom of the box body from top to bottom. According to the invention, the food loading layer and the heating device used for heating the food loading layer are successively arranged on the bottom of the box body from top to bottom, so that the to-be-heated food in the food box can be heated in the manner of heating the food loading layer by the heating device; the user can heat the carried food at any time, is not limited by time and can eat hot food at any time;a food heating device is applied to the outdoor heating food box.

The invention is suitable for the technical field of computers and provides a web page collecting method and device as well as a browser. The web page collecting method comprises the following steps of receiving a web page collecting command, and obtaining a web page link corresponding to a web page; calling a web page grabbing server in a cloud server farm to grab web page content corresponding to the web page link according to the web page link; saving the web page content in a cloud storage server in the cloud server farm. According to the web page collecting method and device as well as the browser, which are disclosed by the invention, the cloud storage of the collected web page content is realized, and the long-term validity of the collected web page is ensured, so that the collected web page content is not limited by time and access addresses, and the function of a bookmark of the browser is expanded.

The invention discloses a novel mine safety monitoring system with a coal spontaneous combustion monitoring function. The novel mine safety monitoring system comprises an ethylene gas detection case, wherein a first electric gas extracting pump, a first drying agent tank, a noble metal catalyst tank and an ethylene sensor are arranged in a case body of the ethylene gas detection case; the gas inlet end of the noble metal catalyst tank is directly communicated with the inner space of the case body; the gas outlet end of the noble metal catalyst tank is communicated with the gas inlet end of the ethylene sensor; the gas outlet end of the first gas extracting pump is connected with the gas inlet end of the first drying agent tank; the gas outlet end of the first drying agent tank is directly communicated with the inner space of the case body; the gas inlet end of the first electric gas extracting pump is connected with a gas inlet pipe joint; the first gas inlet pipe joint is connected with a first ventilating pipeline; the first ventilating pipeline is connected with an extending pipe outside the case body. The novel mine safety monitoring system with the coal spontaneous combustion monitoring function can effectively monitor gas in a region to be detected in real time through gas sampling and is high in monitoring accuracy and low in maintenance cost; monitoring for coal spontaneous combustion significant gas is informationized and automatic.
