[0022] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0023] like Figures 1 to 4 As shown, a marine screw chiller health management module device of the present invention mainly includes a CPCI computer and related accessories, a power module, a vibration monitoring module, a health management module electric control box, a vibration acceleration sensor, a chiller management module software, etc.

[0024] The equipment consists of a chiller management module control box and a vibration monitoring device. The interior of the chiller health management module control box is divided into two parts, the left side is where the chiller health management module control box (CPCI computer and related accessories) is arranged, and the cage mounting bracket is a retractable and flip-over rail installation, which is convenient for maintenance and installation; the right side of the box is the electrical component layout area, where filters, power supplies, circuit breakers, switches, terminals and other components are arranged. Cooling fans are arranged on the upper part of the back panel and the upper part of the left side panel of the box; shielded ventilation windows and baffles are arranged at the bottom of the box to ensure heat dissipation, ventilation and dust prevention requirements. The chiller health management module control box adopts a mature sealing process when designing the box structure. The box adopts a double-folding and flanging process. After being pressed with the electromagnetic compatibility sealing material on the box cover, it can meet the IP44 requirements. Specifically in terms of device selection, the protection level of the external electronic devices is greater than or equal to IP44. The gap between the box covers is sealed with electromagnetic shielding and sealing materials to meet the protection requirements. The cable entry of the box adopts aviation plugs and stuffing boxes. The aviation plug adopts the rainproof YMG series. Four wire rope vibration isolators (GSG-30) are installed at the bottom of the control box, and two wire rope vibration isolators (GSG-10) are installed on the back. The control box is installed on the bracket at the bottom, and the wire rope vibration isolator on the back is fixed on the bulkhead bracket on the back. This design method ensures that the CPCI computer will not be affected too much in the ship vibration environment. The vibration monitoring device consists of a vibration acceleration sensor, a vibration monitoring module (vibration monitoring module box, vibration monitoring electronic control module) and a ship low-noise cable. The vibration acceleration sensor is used to collect the acceleration signal of the chiller foot. After the vibration monitoring electronic control module undergoes certain changes and data processing operations, it is stored and remotely transmitted to the chiller health management module control box.

[0025] The equipment is also equipped with a set of chiller management module software, which is designed and developed based on the domestic operating system (Kylin operating system), and provides chiller health assessment and early warning functions (including electrical fault warning, thermal fault warning, mechanical fault warning), chiller preventive maintenance decision-making assistance (including preventive maintenance decision-making assistance content for the above-mentioned warnings), chiller fault maintenance decision-making assistance (including maintenance decision-making assistance for chiller faults), and has algorithm library, model library, knowledge base and maintenance information management update function (with offline update of warning model library and maintenance decision-making assistance information library) and upper-level information interaction (specifically uploading chiller warning information and health assessment report content to the regional monitoring box) and other functions, which can realize the functional requirements of the health management module and improve the operation management level and comprehensive guarantee capability of the screw chiller.

[0026] During the design process, the equipment fully considered the impact of environmental conditions such as salt spray, mold, tilt, sway, vibration, and electromagnetic compatibility, and can meet the actual ship use environment requirements.

[0027] Chiller health management module control box, such as Figure 2 , 3, 4 as shown.

[0028] Before the equipment officially works, the chiller health management module and the chiller need to be connected according to the wiring diagram so that the communication between the two can be established successfully. Then the user needs to press the "power" button on the electric control box to turn on the power. When the power is turned on, the device enters the self-test, and the operation light flashes after the self-test is completed.

[0029] After the chiller health management module control box is powered on, the chiller health management module successfully establishes communication with the chiller, and starts to collect typical working conditions and extract characteristic parameters. The chiller health management module software processes the data through corresponding algorithms and models, and outputs the corresponding chiller health assessment and early warning functions (including electrical fault early warning, thermal fault early warning, mechanical fault early warning), chiller preventive maintenance auxiliary decision-making (including preventive maintenance auxiliary decision-making content for each of the above warnings), chiller fault maintenance auxiliary decision-making (including maintenance auxiliary decision-making functions for chiller faults). Users can view the current diagnostic information in the upper monitoring system or the external display interface.
