An automatic detection and early warning method for an obstacle based on a smartphone belongs to an obstacle detection and automatic warning method. The automatic detection and early warning method for the obstacle includes the following steps: calculating an included angle theta between the smartphone and a horizontal direction by using an acceleration sensor embedded in the smartphone, and further estimating a straight-line distance Lg from the smartphone to a front detection point and a horizontal distance Lh from a user to the front detection point; calculating an actual distance Lt from the smartphone to the front detection point by a camera; and determining whether an obstacle occurs in front by calculating the difference between Lt and Lg. The scheme of the invention has the advantages that: whether the obstacle exists in front is detected by comparing the difference between the actually measured distance and the estimated distance in real time, whether the obstacle occurs in front of the user can be measured accurately, simply and quickly, and the probability of occurrence of tragedies that the phubbers collide with trees or pedestrians during walking, or even cause car accidents or fall into rivers can be effectively reduced.

The invention discloses a system and a method for wirelessly monitoring the water drinking behavior of sows raised in a group based on a machine vision technology. The system comprises a plurality of pieces of water drinking place equipment, gateway nodes and a central server, wherein each water drinking place equipment is arranged at a water drinking place in each sow house to be monitored, used for sensing approaching of the sows and triggering each processor to record water drinking time and flow, and wirelessly connected with the central server through the gateway nodes by using a network. The water drinking behavior is an important basis for judging whether the sows are healthy. The system can accurately monitor the daily water drinking frequency of the sows and the daily total consumption of water resources by using an automatic technology, and can automatically send the serial number of a sow individual which abnormally consumes water to a feeder, so that the sow can be timely concerned, the growth and reproduction of the sows are slightly influenced by diseases, and the economic benefit of sow raising is effectively improved.

The invention provides a call state prompting method and a call state prompting device. The method can comprise the steps of when a calling event is detected, acquiring a connection waiting state of acaller; and when the calling event is connected, prompting the caller according to the acquired connection waiting state. According to the technical scheme of the method and the device provided by the invention, an effective connection prompt can be provided for the caller when the call is connected, and improvement of communication efficiency is facilitated.

The present invention provides an augmented reality information transmission method and a mobile augmented reality server. The method comprises: a mobile augmented reality server receiving a subscription request or unsubscription request from a mobile augmented reality client and about a notification of an augmented reality content and / or an augmented reality target (S102); the mobile augmented reality server managing a push configuration of the augmented reality content and / or the augmented reality target, designated by a user, in the request (S104); and the mobile augmented reality server initiating a push request of the augmented reality content and / or the augmented reality target to the mobile augmented reality client according to the push configuration (S106). The present invention enables an augmented reality terminal to in time obtain augmented reality information about which the augmented reality terminal is concerned.

Methods, apparatus, electronic devices, and computer readable media for monitoring health status. The present application provides a method for monitoring health status, which belongs to the technical field of monitoring. The method includes: detecting whether there is a user through the infrared sensing device; if the user is detected, controlling the ultrasonic device to obtain the organ waveform diagram of the user, and controlling the temperature measuring device to obtain the body temperature information of the user, and the Feedback body temperature information to the preset terminal; judge whether the organ waveform is normal; if the organ waveform is abnormal, feed back the disease information corresponding to the organ waveform to the preset terminal. This application can facilitate Know the user's health information in a timely manner to ensure that users pay attention to their health in a timely and convenient manner.

The invention discloses an induction furnace water temperature constant automatic control system comprising an induction furnace body which has a hollow cylindrical structure comprising an internal cylinder and an external cylinder. A bar-delivering device is fixed at the side surface of the external cylinder. A clamping disc is fixedly installed on the bar-delivering device. The clamping disc is arranged exactly above the induction furnace body. The side surface of the top part of the external cylinder is communicated with a water inlet pipe and a water outlet pipe. The water inlet pipe and the water outlet pipe are respectively provided with a valve A and a valve B. The system also comprises a heater, a temperature sensor, a liquid flow meter and a photosensitive sensor. Besides, the valve A and the valve B are connected with a PLC controller. The invention also discloses a control method of the induction furnace water temperature constant automatic control system. With combined action of the heater, a temperature controller, the PCL controller, the temperature sensor, the liquid flow meter and the pipeline transmitting valves, the objective of induction furnace water temperature constant automatic control is realized so that the structure is simple, the technology is table, lagging is reduced and the effect is obvious, and thus the induction furnace water temperature constant automatic control system is beneficial for wide-range popularization and use in the optical fiber manufacturing industry.
