Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

Example one

The embodiment of the invention provides a remote assistance method, which is applied to a first terminal. Fig. 1 is a flowchart illustrating a remote assistance method according to a first embodiment of the present invention; as shown in fig. 1, the method includes:

step 101: a first terminal collects a first parameter; the first parameter is used for representing the state of a user holding the first terminal.

Here, the first terminal is a help terminal, i.e., a terminal device used by a help seeker. In this embodiment, the first terminal may be: terminal equipment such as smart mobile phone equipment, panel computer equipment or wearable electronic equipment (like intelligent wrist-watch or intelligent bracelet) that have communication function. The first terminal can comprise a handheld sensing device, and the first parameter is acquired based on a sensor in the handheld sensing device.

Wherein the first parameter comprises: a pressure, a contact time, a contact speed, or a body temperature of the user holding the first terminal. Then, in this step, the acquiring the first parameter includes: collecting pressure, contact time, contact speed or body temperature of a user holding the first terminal; specifically, the pressure, the contact time, the contact speed or the body temperature of the user holding the first terminal is acquired through the hand-held sensing device. Wherein, the sensor in the hand-held sensing device may include: a pressure sensor and a temperature sensor; the pressure, the contact time and the contact speed of a user holding the first terminal can be acquired through the pressure sensor; the body temperature of the user can be acquired through the temperature sensor.

Step 102: and when the first terminal determines that the first parameter meets a first preset condition, triggering to obtain a second parameter, wherein the second parameter is used for representing an environment parameter where the first terminal is located.

Here, a first preset value interval is pre-stored in the first terminal; the determining that the first parameter meets a first preset condition includes:

when the first parameter is in the first preset value interval, determining that the first parameter does not meet a first preset condition;

and when the first parameter is not in the first preset value interval, determining that the first parameter meets the first preset condition.

In this embodiment, the first preset value interval is a parameter interval when the user holds the first terminal in a normal condition; the normal condition is a condition when the user normally uses the first terminal. The first preset value interval comprises at least one group; for example, when the first parameter is the body temperature of the user, the first preset value interval is a first preset body temperature value interval; and the first preset body temperature value interval is the body temperature value interval of the user in a healthy state. When the first parameter is the contact time, the contact time is the time for triggering help, and in this embodiment, the first preset value interval corresponding to the contact time is a set specified time interval, such as 5 seconds to 8 seconds. And when the first parameter is the pressure and the contact speed of the first terminal held by the user, the first preset value interval is obtained by sampling for multiple times.

Specifically, the first preset value interval is obtained in the following manner: setting sampling N times (N is an integer, such as 100); collecting and obtaining N measured values, and taking an integer after each measured value is 10; calculating the probability of occurrence of each of the N measurements, e.g., if there are 10 measurements of 15 out of 100 measurements, then the probability of occurrence of the 15 measurements is 10%; further, the occurrence probability of each measurement value is sorted from large to small, the occurrence probabilities are accumulated from large to small until a preset proportion value (for example, 80%) is accumulated, the largest measurement value and the smallest measurement value are obtained, and the interval range between the largest measurement value and the smallest measurement value is used as the first preset value interval.

Based on the obtaining mode of the first preset value interval, when the collected first parameter is in the first preset value interval, the occurrence probability of the first parameter is proved to be very high, namely the moment of collecting the first parameter is the moment when the user is in a normal condition; when the acquired first parameter is not in the first preset value interval, it is indicated that the occurrence probability of the first parameter is very small, that is, the moment of acquiring the first parameter is likely to be the moment when the user is in danger and needs to ask for help.

Based on this, when the first terminal determines that the first parameter meets a first preset condition, that is, when it is stated that the occurrence probability of the first parameter is small, a second parameter is triggered to be obtained, where the second parameter includes: image data, audio data, and coordinate data. In this embodiment, the first terminal includes: the device comprises an image acquisition unit, an audio input unit and a positioning unit; the triggering to obtain the second parameter includes:

triggering and starting an image acquisition unit, and acquiring image data through the image acquisition unit;

triggering and starting an audio input unit, and acquiring audio data through the audio input unit;

and triggering and starting a positioning unit, and acquiring coordinate data through the positioning unit.

Specifically, the first terminal triggers and calls an image acquisition interface, starts the image acquisition unit, and shoots the current scene of the image acquisition unit to obtain image data; the first terminal triggers and calls a recording function interface, starts the audio input unit, and performs audio acquisition on the environment where the first terminal is located to obtain audio data; the first terminal triggers and starts a positioning unit, which may be a Global Positioning System (GPS) unit, to acquire coordinate data of a location where the first terminal is located. Of course, the order of the image acquisition unit, the audio input unit and the positioning unit triggered and called by the first terminal is not sequential, and is not limited to the provided starting order.

On the other hand, when the first parameter is not in the first preset value interval, it is indicated that the occurrence probability of the first parameter is small, that is, the time of acquiring the first parameter is the time when the user is in an abnormal condition; the method further comprises: determining a relative numerical value relationship of the first parameter in a second preset numerical value interval, and determining a grade attribute parameter of the first parameter based on the relative numerical value relationship.

Specifically, taking the sampling N times (where N is an integer, for example, 100) as an example, if an interval range between the maximum measurement value and the minimum measurement value of the preset proportional value (for example, 80%) is used as the first preset value interval, the second preset interval is a value interval composed of all the measurement values in the proportional value range of 80% to 100%; based on the first parameter, obtaining the occurrence probability of the measurement point represented by the first parameter; the smaller the occurrence probability is, the smaller the probability of acquiring the first parameter is, and the more critical the situation of the first terminal is possibly; the greater the occurrence probability, the greater the probability that the first parameter is collected, and the situation that the first terminal is in may not be very critical. Dividing the level attribute of the first parameter into M levels (where M is a positive integer, such as 3 or 4) based on the occurrence probability of the measurement point represented by the first parameter, and accordingly, dividing the occurrence probability of all measurement points no longer in the first preset value interval into 3 or 4 interval ranges, where each interval range corresponds to one level attribute, and the smaller the probability, the higher the corresponding level attribute, and the lower the probability; and when the first parameter falls into a certain interval range, obtaining the level attribute parameter corresponding to the interval range.

Step 103: and generating first data according to the second parameters in a preset mode, and sending the first data to a second terminal through a server so that the second terminal outputs alarm information according to the first data.

Here, the generating the first data according to the second parameter in a preset manner includes: and combining the image data, the audio data and the coordinate data into first data according to a preset combination mode.

Specifically, the first data includes three parts, namely, the image data, the audio data, and the coordinate data, and each part of data includes: data type, data length, and serialized data. Taking the image data as an example, the first terminal performs serialization coding on the image data and calculates the length of coded data, and then the data type is the image data, the data length is the calculated length of the coded data, and the serialization data is the image data after serialization coding.

And the first terminal encodes the image data, the audio data and the coordinate data according to a preset encoding mode to obtain first data.

In this embodiment, the first data further includes the rank attribute parameter.

correspondingly, the sending the first data to the second terminal includes:

and the server searches prestored second data based on the first identifier, obtains a second identifier associated with the first identifier, and sends the first data to a second terminal to which the second identifier belongs.
