Wireless remote control and alarm system for electric propulsion ship

Abstract

The invention relates to a wireless remote control and alarm system for an electric propulsion ship. The system comprises a plurality of wireless APs and at least one mobile control terminal; the plurality of wireless APs are distributed at various areas of the ship so as to form a wireless local area network, and are connected with a network switch on the ship; the mobile control terminals establish communication with a ship PLC through the wireless local area network formed by the plurality of wireless APs, so as to complete the information exchange of ship data and perform entire-ship-arearemote control, monitoring and warning according to the ship data, wherein the ship PLC is connected with the network switch and sets the priority of a control authority. According to the wireless remote control and alarm system for the electric propulsion ship of the invention, the wireless network communication mode is applied to the entire ship, and a corresponding number of mobile control terminals are arranged on the ship as needed, and therefore, extremely efficient and portable full-ship-area control is realized, the movement range limitations of staff are eliminated, and the control authority of the ship is configured on the mobile control terminals so as to be adopted as a redundant control mode of the ship, and is of great significance for the improvement of the safety of the ship.

Description

Technical field [0001] The invention relates to the technical field of large ocean-going ships, in particular to a wireless remote control and alarm system applied to electric propulsion ships. Background technique [0002] At present, ships adopt wired data transmission and wired control methods to realize the monitoring of ship information and control of ships at fixed locations. However, this wired method severely limits the movable range of ship staff, and there are the following problem: [0003] 1. The call method usually used on ships is wired telephone mode. The call establishment process is: first know the location of the other party, and then query the fixed number assigned to that location to make a call, but if the current person is not in that location, you cannot The call connection is successfully established, and the communication is invalid; [0004] 2. The current ship’s wired control mode severely limits the range of activities of the ship’s pilot, restricting th...

AI Technical Summary

Problems solved by technology

[0002] Currently ships use wired data transmission and wired control methods to monitor ship information and control ships at fixed locations, but this wired method severely limits the range of activities of ship staff, and has the following problems question:

[0003] 1. The current call method usually used on ships is the wired telephone mode. The establishment process of the call is: first know the location of the other party, and then inquire the fixed number assigned to the location to make a call, but if the current person is not at the location, you cannot The call connection is successfully established, but the communication is invalid;

[0004] 2. The current ship's wired control method severely limits the range of activities of the ship's pilot, confining the pilot to the fixed area of ​​the bridge, and can only transcribe the operation password according to the observed situation, so that the sailor can perform the operation , which is extremely inconvenient; on the other hand, in the process of information transmission, there will be operational errors due to differences in human cognition of ship dynamic performance and differences in business capabilities, which will affect the safety of ships;

[0005] 3. The number of equipment on the ship is increasing, and the structure is becoming more and more complex at the same time, and the coupling degree of information between the equipment is also increasing. For the safety of the ship, it is necessary to monitor the alarm information of each equipment in a timely and efficient manner to prevent leakage of alarm information. Listening or delaying processing may lead to serious accidents. Currently, only areas such as the central control room, driving console, dining room, and room on the ship can monitor and display equipment alarm status. At the same time, with the development trend of large ships, The alarm information display and monitoring scheme only in a few fixed locations brings great inconvenience to the ship's staff on the whole ship patrol, maintenance and other work;

[0006] 4. The current laying of network lines on ships is becoming more and more complicated, and the probability of corresponding network failures will also increase. The emergence of key network failure information will pose a great threat to the information transmission and safe navigation of ships. However, current ships There is no dedicated network communication status monitoring equipment on the Internet, which is not conducive to efficient maintenance of the network;

[0007] 5. Since the current ship’s regular maintenance of equipment mainly adopts the timing method, recording the opening and closing time of each equipment, and then formulating equipment maintenance and maintenance plans according to the total running time, but this kind of maintenance way is not efficient

The operating conditions of ship equipment change in real time with the ocean currents in the external ocean and the operation of the ship's internal equipment, so there will be light loads and heavy loads, so the impact on the equipment under these two non-standard conditions is different Therefore, the accumulation of simple time cannot reflect the degree of wear of the internal components of the equipment, and such a regular maintenance method is not conducive to reducing the maintenance cost of the ship;

[0008] 6. Ship safety includes equipment safety and personnel safety. At present, the safety of ship personnel is mainly carried out through safety education to improve safety awareness and wearing safety helmets and work shoes. There is no special personnel safety device on the ship

On the other hand, during the working process, most of the conversations of the staff are realized through the walkie-talkie. Even if there is an accident and the need to call for help is realized through the walkie-talkie, but due to the steel structure of the large ship, there will be no The wireless signal of the walkie-talkie produces a natural shielding effect, which cannot effectively guarantee the stability and immediacy of communication, so the unreliability of the performance cannot effectively guarantee the safety of personnel
