Any cable failure of electric valves and level sensors will cause the electric valves or level sensors to malfunction, resulting in low redundancy; 3. It does not have fault addressing capability; 4. The workload of subsequent maintenance is large. Utility Model Content

[0005] To achieve the above and other related objectives, this utility model provides the following technical solution:

[0006] A ring network structure marine valve remote control liquid level telemetry system includes a valve remote control data acquisition component and a liquid level telemetry data acquisition component connected to the valve remote control data acquisition component via a data communication line; wherein, the valve remote control data acquisition component includes a valve remote control data acquisition box and n electric valve actuators, the n electric valve actuators are sequentially connected to each other via cables to form a ring network structure, and the first electric valve actuator and the nth electric valve actuator are also connected to the valve remote control data acquisition box via cables respectively;

[0007] The liquid level telemetry data acquisition component includes a liquid level telemetry data acquisition box connected to the valve remote control data acquisition box via a data communication line and n liquid level telemetry local processing units.

The first liquid level telemetry local processing unit and the nth liquid level telemetry local processing unit are also connected to the liquid level telemetry data acquisition box via cables.

[0019] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. It should be noted that, unless otherwise specified, the following embodiments and features described herein can be combined with each other.

[0020] Please see Figures 4 to 6 This utility model provides a marine valve remote control liquid level telemetry system with a ring network structure, including a valve remote control data acquisition component and a liquid level telemetry data acquisition component connected to the valve remote control data acquisition component via a data communication line; wherein, the valve remote control data acquisition component includes a valve remote control data acquisition box and n electric valve actuators, the n electric valve actuators are connected sequentially to form a ring network structure via cables, and the first electric valve actuator and the nth electric valve actuator are also connected to the valve remote control data acquisition box via cables respectively. It should be noted that the cables in this embodiment include data communication lines and power lines;

[0021] exist Figure 5 In this system, the valve remote control data acquisition box contains a first main processing unit, and the electric valve actuator contains a valve remote control local processing unit. n valve remote control local processing units are sequentially connected via data communication lines in a cable to form a ring network structure, and these n units exchange information via these data communication lines. Furthermore, the first and nth valve remote control local processing units are also connected to the first main processing unit via data communication lines in the cable, and these units exchange information with the first main processing unit via these data communication lines.

[0022] It should be noted that the n electric valve actuators in this invention are connected together by cables in a sequential manner from near to far and then from far to near, thus greatly reducing the amount of cables used and the workload of cable laying. Furthermore, because each electric valve actuator is connected to the preceding and following electric valve actuators via cables, even if one cable fails, the actuator can still communicate with other electric valve actuators via the other cable. Therefore, any single-point failure will not cause a failure of all equipment. Moreover, the communication between the first main processing unit and the valve remote control local processing unit within the electric valve actuator enables this invention to have fault addressing capabilities; any cable or electric valve failure in the ring network can pinpoint the fault point. Additionally, the valve remote control data acquisition box is connected to the engine room monitoring and early warning system, the bilge ballast main pump starter, and the fuel transfer pump starter, respectively. The valve remote control data acquisition box is also connected to the loading computer and the valve remote control liquid level remote control industrial control computer.

[0023] exist Figure 6The liquid level telemetry data acquisition component includes a liquid level telemetry data acquisition box connected to a valve remote control data acquisition box via a data communication line, and n liquid level telemetry local processing units. The valve remote control data acquisition box and the liquid level telemetry data acquisition box exchange information via a data communication line. The n liquid level telemetry local processing units are connected sequentially via cables to form a ring network structure. The first liquid level telemetry local processing unit and the nth liquid level telemetry local processing unit are also connected to the liquid level telemetry data acquisition box via cables. Each liquid level telemetry local processing unit is also connected to several liquid level sensors via cables.

[0024] The liquid level telemetry data acquisition box contains a second main processing unit. The first and nth local liquid level telemetry processing units are connected to the second main processing unit via data communication lines in a cable. These units exchange information with the first main processing unit through the data communication lines. It should be noted that the n local liquid level telemetry processing units are connected sequentially via cables in a forward-to-backwards and backward-to-nearest order, significantly reducing cable usage and laying workload. Furthermore, the interaction between the intermediate valve remote control processing unit and the preceding or following valve remote control processing unit is manually configured based on actual conditions; the intermediate liquid level telemetry processing units are also configured in this way. Both the valve remote control data acquisition box and the liquid level telemetry data acquisition box are connected to the ship's main power supply and emergency power supply, which provide power to both.

[0025] Specifically, the valve remote control data acquisition box is used to power the electric valve actuator. The first main processing unit in the valve remote control data acquisition box is used to control the electric valve actuator and receive fault signals from the valve remote control local processing unit in the electric valve actuator. The first main processing unit can perform fault location and fault alarm. It is also used to receive liquid level signals sent from the second main processing unit in the liquid level telemetry data acquisition box, integrate these signals and send them out. The valve remote control local processing unit in the electric valve actuator is used to exchange signals with the first main processing unit, receive action commands and issue alarm signals. The electric valve actuator also receives action commands from the first main processing unit, performs valve opening and closing, and feeds back the opening and closing status and alarm signals.

[0026] The liquid level telemetry data acquisition box powers the local liquid level telemetry processing unit. The second main processing unit within the box controls the local liquid level telemetry processing unit and receives fault signals from it. This second main processing unit can locate and alarm faults, and also sends liquid level signals to the first main processing unit within the valve remote control data acquisition box. The local liquid level telemetry processing unit receives and transmits signals to the second main processing unit, receiving action commands and issuing alarm signals. The liquid level sensor collects liquid level signals and sends them to the local liquid level telemetry processing unit.

[0027] In summary, this invention optimizes the design by adding a central processing unit within the data acquisition box, a valve remote control local processing unit on the electric valve actuator, and a level telemetry local processing unit within the level telemetry data acquisition component, forming a ring network structure. This redundant ring network design significantly reduces cable usage and laying workload. Furthermore, the redundancy of the ring network ensures that any single-point failure will not cause a complete equipment failure. The central processing unit, valve remote control local processing unit, and level telemetry local processing unit enable this invention to provide fault location capabilities; any cable or electric valve actuator fault in the ring network can pinpoint the fault location. Additionally, this invention features a simple network design, facilitates fault diagnosis, and reduces subsequent maintenance workload.

[0028] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit this utility model. All equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
