Problems solved by technology

The start-up conditions of the reporting device in the prior art include overload, air pressure, temperature, and parachute opening force, etc. For example, a utility model patent (patent number: 201721666508.0, announcement date: 2018.09.18) discloses a mechanical pull activation device for life-saving wearable equipment , start the reporting device based on the parachute opening force, but there is a problem of low reliability in the starting of the reporting device in the prior art, such as the above-mentioned patent, there are the following problems: (1) the pilot pulls or Unplugging the pin by mistake, when the ground crew maintains the equipment, pulling or pulling the pin by mistake will cause the position reporting device to start up by mistake; (2) After the pin is used for a long time, the tension response range changes, and if it becomes smaller, it will cause the position reporting device to start up by mistake The probability increases, and if it becomes larger, it will cause the problem of not being able to pull it apart; (3) The surface of the pin will be corroded or oxidized after long-term use, and the contact conductivity will deteriorate, which will cause the reporting device to start up by mistake

Embodiment 1

[0035] A kind of start-up structure of reporting device 1, such as figure 1 As shown, it includes an reporting device 1 , and also includes an umbrella belt manipulation belt 2 , an upper connection belt 3 , an upper buckle 4 , a lower buckle 5 , a lower connection belt 6 , a pull pin 7 and a sensor switch 8 .

[0036] The upper end of the upper connecting belt 3 is fixedly connected to the umbrella belt control belt 2 by sewing, the upper end of the upper buckle 4 is fixedly connected to the lower end of the upper connecting belt 3 by winding, the upper buckle 4 and the lower buckle 5 are snapped together, and the upper buckle 4 and the lower buckle 5 clamping force is greater than the upper limit of the threshold value of the parachute opening force (the upper limit and lower limit of the threshold value of the parachute opening force will be given when the umbrella leaves the factory, and the parachute opening force is usually within the threshold value when the parachute is...

Embodiment 2

[0040] A temperature-based start-up method for a position reporting device, based on the start-up mechanism of Embodiment 1, includes the following steps:

[0041] Step 1: Obtain the temperature values ​​Tt1, Tt2, and Tt3 measured by the three temperature-sensing strain gauges, and take the average value Tt after removing abnormal values; this embodiment adopts the following steps to remove abnormal values, and judge whether Tt1 is greater than the average value of Tt2 and Tt3 2 times, if it is judged that Tt1 is abnormal data and eliminated, it is judged whether T2 is greater than twice the average value of Tt1 and Tt3, and if it is judged that Tt2 is abnormal data and eliminated, it is judged whether Tt3 is greater than the average value of Tt1 and Tt2 2 times, if so, it is judged that Tt3 is abnormal data and eliminated.

[0042]Step 2: Determine whether Tt is greater than the temperature limit T0, if so, enter step 3, otherwise return to step 1; in this step, obtain the al...

Embodiment 3

[0046] A kind of starting method of position reporting device based on parachute opening force, based on the starting mechanism of embodiment one, comprises the steps:

[0047] Step 1: Determine whether the pull pin is pulled, if so, go to step 2, otherwise go to step 8.

[0048] Step 2: Obtain the temperature values ​​Tt1, Tt2, and Tt3 measured by the three temperature-sensing strain gauges, and take the average value Tt after removing abnormal values; Step 3: Determine whether Tt is greater than the temperature limit T0, if so, go to step 4, otherwise go to Step 5, in this step, obtain the altitude values ​​Ht1, Ht2, and Ht3 measured by the three barometric altitude sensors, and take the average value Ht after removing the abnormal values. T0, T0 corresponding to different Ht is obtained through pre-experimental measurement; steps 2 and 3 prevent accidents in step 1 and cause misjudgment.

[0049] Step 4: Turn on the location reporting device and report the location;

Abstract

The invention discloses a start-up structure and a start-up method of a position reporting device, wherein the start-up structure includes a position reporting device, and also includes an umbrella belt control belt, an upper connecting belt, an upper buckle, a lower buckle, a lower connecting belt, a pull pin and a sensor Switch: The sensor switch is installed on the upper end of the position reporting device, the shell, the inner cavity, and the three-axis 60° strain rosette. The material for pulling out the pin is a magnetic conductor. The main control board of the position reporting device is located directly below the inner cavity. Circuit; at least three air pressure altitude sensors are installed in the position reporting device. The start-up structure and start-up method of the present invention have high reliability and reduce the probability of false start-up of the position reporting device.

Description

technical field [0001] The invention relates to the technical field of control of a position reporting device after a pilot is in distress at sea, in particular to a start-up structure and a start-up method of the position report device. Background technique [0002] When the pilot is in distress in the air, it is hoped that the reporting device carried by the pilot will be turned on at the first time to report the position. The start-up conditions of the reporting device in the prior art include overload, air pressure, temperature, and parachute opening force, etc. For example, a utility model patent (patent number: 201721666508.0, announcement date: 2018.09.18) discloses a mechanical pull start device for life-saving wearable equipment , start the reporting device based on the parachute opening force, but there is a problem of low reliability in the starting of the reporting device in the prior art, such as the above-mentioned patent, there are the following problems: (1) ...
