Problems solved by technology

The above-mentioned ways of tracing people are all passive, and cannot grasp the dynamics of the whole ship in real time. Especially when unexpected situations occur, such as emergency situations such as people falling into the water, the shortcomings of the people-seeking methods in the prior art are particularly obvious, and cannot be detected in time. It was found that the crew fell into the water, and after the discovery of the crew falling into the water, it was impossible to accurately locate the crew who fell into the water, which made the efficiency of search and rescue low and posed a great threat to the safety of the crew who fell into the water

Embodiment 1

[0039] This embodiment provides a positioning method for ship personnel, such as figure 1 shown, including the following steps:

[0040] Step S101: the base station 10 transmits a wireless inquiry signal; wherein, the wireless inquiry signal carries the serial number of the base station 10 to which it belongs;

[0041] Step S102: The positioning terminal 20 worn by the crew receives at least one wireless inquiry signal, and determines that the wireless inquiry signal with the strongest signal strength among the at least one wireless inquiry signal is the target wireless inquiry signal;

[0042] Step S103: The positioning terminal 20 judges whether the number of the base station 10 to which the target wireless inquiry signal belongs is the same as the number of the base station 10 to which the target wireless inquiry signal received by the positioning terminal 20 last time; if they are the same, execute steps S104~S105; if not, execute Steps S106~S107;

[0043] Step S104: The p...

Embodiment 2

[0053] Embodiment 2 provides a ship personnel positioning system, which is used to implement the ship personnel positioning method described in Embodiment 1. Such as figure 2 As shown, the positioning system of the ship's personnel includes a base station 10, a positioning terminal 20, and a management center device 30:

[0054] Wherein, the base station 10 includes: a signal transmitting unit 101, which is used to transmit a wireless inquiry signal; wherein, the wireless inquiry signal carries the serial number of the base station 10 to which it belongs;

[0055] Wherein, the positioning terminal 20 is worn on the ship's personnel, including: a signal receiving unit 201, configured to receive at least one wireless inquiry signal, and determine that the wireless inquiry signal with the strongest signal strength among the at least one wireless inquiry signal is the target wireless inquiry signal; A judging unit 202, used to judge whether the serial number of the base station ...

Embodiment 3

[0070] This embodiment provides another positioning method for ship personnel, such as image 3 shown, including the following steps:

[0071] Step S301: The positioning terminal 20 calls the heart rate detection bracelet 40 worn by the crew at the preset calling time;

[0072] In the embodiment of the present invention, each crew member on the ship wears an exclusive bracelet, which is equipped with a heart rate detection sensor for detecting the crew's heart rate sign data, and the bracelet is also equipped with a positioning terminal 20 , the positioning terminal 20 and the heart rate detection sensor can communicate with each other. After wearing the wristband, the crew can set the time interval between two adjacent times when the positioning terminal 20 calls the heart rate detection sensor. It is necessary to ensure that the set time interval does not exceed 30 minutes. The time interval is set to 1 minute, and the time interval can also be set to 5 minutes. The embodim...

Abstract

The invention discloses a positioning method and system for ship personnel, wherein, the method comprises: a base station transmits a wireless query signal; a positioning terminal determines that the received wireless query signal with the strongest signal strength is the target signal; and the positioning terminal judges that the target signal belongs to Whether the number of the base station is the same as the number of the base station received last time; if yes, the positioning terminal sends the location coverage signal to the above-mentioned base station, so that the above-mentioned base station sends the location coverage signal to the management center equipment; if not, the positioning terminal sends the location coverage signal to the above-mentioned base station Send the position query signal and the heart rate data of the crew, so that the information points contained in the base station can calculate the position data of the positioning terminal, and send the calculated position data and the heart rate data of the crew to the management center equipment. The invention can locate the ship's personnel in real time, grasp the dynamics of the entire ship's personnel, and can rescue in time when a crew member falls into the water, so as to ensure the life safety of the ship's personnel.

Description

technical field [0001] The invention relates to the technical field of positioning, in particular to a positioning method and system for ship personnel; it is suitable for ships with many personnel, especially scientific research ships, cruise ships and passenger ships. Background technique [0002] In the prior art, ships belong to multi-chamber structure. Since the hull is mostly made of metal, there are many barriers to block, especially the high density of personnel such as scientific research ships, cruise ships, and passenger ships, and the ship personnel are not familiar with water and ship structures. Therefore, in order to confirm the location information of personnel during the operation, communication can only be carried out through broadcast calls, telephone tracing, and walkie-talkies. As a scientific research ship, since the crew includes a large number of students to go out to sea, the requirements for personnel safety are higher and the responsibilities are g...
