Description

Technical Field

[0001] The invention relates to the field of lifesaving tools, and in particular to a control method for a heating control system of a polar life raft. Background Art

[0002] Polar operating conditions pose great difficulties to life-saving work. The temperature is extremely low, even reaching minus 40 or 50 degrees Celsius. Many equipment cannot work normally, including components and circuits made of various organic materials, making rescue work extremely difficult.

[0003] A life raft is a life-saving tool for use on the water surface. It is usually placed in a storage tube and fixed on a life raft frame. It can only be used when the life raft is separated from the life raft frame, the bow cable is activated, and the life raft is inflated and formed. A heating device is installed in the storage tube of a life raft under polar operating conditions, which can provide heat for the life raft. However, there is currently no corresponding control method to control the heating of the heating device. Summary of the invention

[0004] The object of the present invention is to provide a control method for a heating control system of a polar life raft.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is: a control method of a polar life raft heating control system, comprising the following steps: S1: the manager receives external power and supplies power to at least one controller through the main power output interface, and sends control instructions through the main data output interface; S2: the controller receives the power and control instructions of the manager, and performs power distribution and data processing through its secondary power input interface and secondary data input interface; S3: the controller adjusts the power output of the electric heating belt of the heating device according to the temperature data received from the temperature sensor to maintain the temperature in the storage cylinder within a preset range; S4: The controller sends a release command to the releaser through the release interface, triggering the mechanical and / or electronic release mechanism of the releaser to achieve the detachment of the life raft from the life raft frame, thereby achieving rapid remote single or group release.

[0006] Compared with the prior art, the advantages of the present invention are: the temperature in the storage cylinder is monitored in real time by the temperature sensor, and the controller can automatically adjust the power output of the electric heating cable according to the collected data, so as to ensure that the life raft can always maintain a safe use temperature in an extremely cold environment, and significantly improve the availability and rescue efficiency of the life raft. Dynamic adjustment of the heating power can not only maintain the temperature in the life raft storage cylinder, but also effectively avoid energy waste, extend the system working time and equipment life, which is particularly important for polar rescue missions with limited resources. The linkage design of the controller and the releaser realizes the automatic release of the life raft. Once the release instruction of the manager is received, the mechanical and electronic release mechanism of the releaser can be quickly triggered, shortening the preparation time of the life raft and gaining more survival opportunities for the trapped people. The data communication and power distribution between the manager and the controller ensure the information synchronization and functional coordination between the components of the system, improve the stability and response speed of the entire heating control system, and at the same time, the application of the encrypted communication protocol enhances the security of data transmission. The centralized control design of the manager simplifies the operation process of the system. Through the human-computer interaction interface, the operator can easily monitor the system status and adjust the parameters. At the same time, the self-diagnosis function of the system helps to timely discover and repair potential faults, reducing maintenance costs and time. This control method is specially designed for life-saving work under polar operating conditions. Even in extremely low temperature environments, it can ensure the normal operation of the life raft heating system and release mechanism, greatly improving the feasibility and safety of rescue work.

[0007] In some embodiments of the present invention, in step S1, the main output interface group of the manager is connected to the controller.

[0008] In some embodiments of the present invention, in step S2, the controllers are connected in series via a secondary output interface group and a secondary input interface group to form a communication link to ensure continuous transmission of power and data.

[0009] In some embodiments of the present invention, in step S3, the controller dynamically adjusts the power output of the electric heating tape according to a preset heating strategy and real-time temperature feedback to achieve precise temperature control.

[0010] In some embodiments of the present invention, in step S4, after receiving the release instruction from the manager, the controller immediately sends a signal to the releaser to trigger the release mechanism, thereby ensuring that the life raft can be quickly detached from the life raft frame to achieve rapid remote single or group release.

[0011] In some embodiments of the present invention, the method further comprises step S5: through the human-computer interaction interface of the manager, the operator can set the heating parameters and the release threshold and monitor the real-time status of the system.

[0012] In some embodiments of the present invention, in step S3, the power output of the electric heating tape is adjustable, ensuring that the system can dynamically adjust the heating efficiency according to the ambient temperature and the needs of the life raft, thereby saving energy.

[0013] In some embodiments of the present invention, in step S4, the releaser includes at least one mechanical release mechanism and at least one electronic release mechanism, and the double protection ensures the reliable release of the life raft.

[0014] In some embodiments of the present invention, the method further includes step S6: the communication connection between the manager and the controller adopts an encryption protocol to ensure the security of data transmission.

[0015] In some embodiments of the present invention, the method further includes step S7: the system has a self-diagnosis function, which can automatically detect faults and report them to the manager to achieve timely maintenance and repair. BRIEF DESCRIPTION OF THE DRAWINGS
