Description

Technical Field

[0001] The present invention relates to the field of ship electronic technology, and in particular to a ship-based automatic telephone connection method. Background Art

[0002] The marine automatic telephone system is a must-have system for every ship. The conventional telephone system is connected to the junction box of the automatic telephone control cabinet one by one through the telephone junction box. Since current telephones are all two-wire systems, the telephone junction boxes on the market only have two wiring terminals.

[0003] like Figure 1 As shown, in this way, each cabin (room) needs to be wired separately to the junction box of the automatic telephone control cabinet, which not only requires a large wiring workload and high labor costs, but also the cost of the cables (also referred to as cables in the present invention) is high. Summary of the invention

[0004] The object of the present invention is to provide a new automatic telephone wiring method for ships, so as to reduce the workload of ship telephone wiring and save materials.

[0005] To achieve the above-mentioned purpose, the present invention designs a method for automatically connecting a ship's telephone. The method comprises designing a type II telephone junction box, wherein the type II telephone junction box is provided with at least four connection terminals (two connection terminals are added to a general telephone junction box, and the mold is newly opened and customized). At least two adjacent cabins (or rooms) form a group of cabins, and a type II telephone junction box is installed in one of the cabins. At least four-core cables are used to connect the four terminal inlets of the type II telephone junction box and the outlet of the junction box of the automatic telephone control cabinet. The outlet ends of two of the four terminals are connected to the telephone outlets of the junction box and then connected to the telephone terminal of the cabin; the outlet ends of the other two terminals are connected to the telephone terminals of the adjacent cabins.

[0006] Furthermore, the outgoing ends of the other two terminals are respectively connected to the incoming ends of two wiring terminals of a type I telephone junction box in an adjacent cabin through a two-core cable, and then connected to the cabin telephone terminal.

[0007] Furthermore, the group of cabins uses one type-one telephone junction box and one type-two telephone junction box in pairs, and the telephone junction boxes are respectively arranged in two cabins. The type-one telephone junction box includes a universal telephone junction box, which is a mature product in the market (including only 2 wiring terminals).

[0008] Furthermore, the type 1 telephone junction box and the type 2 telephone junction box are respectively arranged on both sides of the common bulkhead of the two cabins. At this time, the length of the 2-core cable connecting the cabins is generally 10 to 20 cm, which is a standardized wiring method that saves the most resources and labor.

[0009] Furthermore, the telephone junction boxes are respectively arranged on different bulkheads of the two cabins. At this time, the length of the 2-core cable connecting the cabins does not exceed the sum of the lengths of the two cabins. The cost saved by this method is slightly reduced. This method is mainly suitable for occasions with special requirements for the installation location of the telephone terminal.

[0010] Furthermore, the outlet ends of the other two terminals are directly connected to the telephone terminal of the adjacent cabin through a 2-core cable.

[0011] The core of the present invention is to design a second-type telephone junction box with 4 wiring terminals, which changes the original scheme that each cabin needs to be wired independently from the junction box of the automatic telephone control cabinet. Instead, two cabins are wired independently as a group, and the original 2-core cable is changed to a 4-core cable, and the cabins in the same group are connected by 2-core cables. The workload of telephone wiring is almost half of the original one, and the cable cost is also significantly reduced.

[0012] For the embodiment where the same group of type 1 telephone junction boxes and type 2 telephone junction boxes are located on both sides of the same bulkhead, the connection of the two telephone junction boxes only requires a very short 2-core cable, generally 10 to 20 cm long. In terms of wiring cost, although the 4-core cable and 2-core cable of the same length are slightly more expensive, they are far less than twice the price. Therefore, overall, since the total cable length is saved by about half of the original amount, on the one hand, the workload of ship cable laying is reduced by half, and the cost of raw materials is also reduced.

[0013] Taking a 50,000-ton oil tanker as an example, the 50,000-ton oil tanker has a total of 52 automatic telephones. The original plan required laying 1,346 meters of 2-core cable (CHJP86 / SC 1X2X0.75); after adopting the new method, it is necessary to lay 663 meters of 4-core cable (CHJP86 / SC 2X2X0.75) and 162 meters of 2-core cable (CHJP86 / SC 1X2X0.75), totaling 825 meters.

[0014] According to the cable market price, the purchase price of CHJP86 / SC 1X2X0.75 is 10 yuan per meter, and the purchase price of CHJP86 / SC2X2X0.75 is 12 yuan per meter. The original planned cable cost is 13,460 yuan. After adopting the new method, the cable cost is 9,576 yuan, and at the same time, the corresponding labor costs for laying and packaging cables are saved, and this invention is applicable to all ship repair and construction projects.

[0015] The above example is based on an oil tanker, which has fewer cabins and a smaller demand for automatic telephones. For passenger ships or cruise ships, the demand for automatic telephones can be as high as several thousand, so the cost and workload savings will be considerable. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0017] The specific implementation of the present invention is further described below in conjunction with the accompanying drawings and embodiments. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.

[0018] Embodiment 1: like Figure 2 , Figure 3 As shown, a method for automatic telephone wiring for a ship is provided, through a specially designed type II telephone junction box, the type II telephone junction box is provided with at least 4 wiring terminals (adding 2 wiring terminals to a general telephone junction box, re-molding, and customizing), every at least two adjacent cabins (or rooms) form a group of cabins, a type II telephone junction box is installed in one of the cabins, at least 4-core cables are used to connect the 4 terminal inlets of the type II telephone junction box with the wiring box outlet of the automatic telephone control cabinet, the outlets of two wiring terminals of the 4 terminals are connected to the telephone outlets of the junction box, and then connected to the telephone terminal of the cabin; the outlets of the other two terminals are connected to the telephone terminals of the adjacent cabins; that is, every 2 cores of the 4-core cable form a group to connect a telephone terminal of a cabin, and this method only needs to lay one cable for each group of cabins, instead of laying one cable for each cabin in the past. The cabin here generally refers to the cabin where the telephone terminal needs to be laid. For a passenger ship, all cabins need to be laid with automatic telephones, so the number of wiring and the actual workload are very large, and the present invention almost reduces the workload of telephone line wiring by half.

[0019] Preferably, the outgoing ends of the other two terminals are respectively connected to the incoming ends of two wiring terminals of a type I telephone junction box in an adjacent cabin through a two-core cable, and then connected to the cabin telephone terminal. Figure 3 The telephone junction box only shows the connection method of the wiring terminals, and the other structures of the telephone junction box are common structures of mature products and are not shown.

[0020] Preferably, the group of cabins uses one type one telephone junction box and one type two telephone junction box in pairs, and the telephone junction boxes are respectively arranged in two cabins. The type one telephone junction box includes a universal telephone junction box, which is a mature product in the market (including only 2 wiring terminals).

[0021] Preferably, the type 1 telephone junction box and the type 2 telephone junction box are respectively arranged on both sides of the common bulkhead of the two cabins. In this case, the length of the 2-core cable connecting the cabins is generally 10 to 20 cm, which is a standardized wiring method that saves the most resources and labor.

[0022] Embodiment 2: The difference from Example 1 is that the telephone junction boxes described in this embodiment are respectively arranged on different bulkheads of the two cabins. At this time, the length of the 2-core cable connecting the cabins does not exceed the sum of the lengths of the two cabins. The cost saved by this method is slightly reduced. This method is mainly suitable for occasions with special requirements for the installation location of the telephone terminal.

[0023] Embodiment 3: The difference from the first embodiment is that the outlet ends of the other two terminals in this embodiment are directly connected to the telephone terminal of the adjacent cabin through a 2-core cable. This embodiment is not shown in the figure.

[0024] That is, the telephone terminals of two adjacent cabins can be directly connected to the Type II telephone junction box. This situation is mainly applicable when the telephones of adjacent cabins are installed back to back. The telephone terminals have their own telephone lines and can be directly connected. This is a relatively convenient, time-saving, labor-saving and material-saving connection method. When the telephone terminals of two adjacent cabins are far apart, a Type I telephone junction box (i.e., an ordinary telephone junction box) is installed in the other cabin and connected to the remaining two terminals of the Type II telephone junction box. The telephone terminal of this cabin is connected to the Type I telephone junction box, i.e., the connection method of Example 1 and Example 2. This method is in line with the standard connection of traditional indoor wiring and is generally recommended.

[0025] The basic principle of the present invention is: by making simple improvements to the traditional telephone junction box, the number of connection terminals is increased from the usual 2 to 4, and there is almost no other change to the structural shape of the junction box, only the internal interface connection is adaptively modified, and two adjacent cabins are taken as a group, and an improved telephone junction box (type II telephone junction box) and an ordinary telephone junction box (type I telephone junction box) are arranged respectively. By utilizing the principle that the wiring directions of adjacent cabins can be consistent, the workload of telephone wiring can be reduced by nearly half; the price of the cable after the core wires are combined is also much lower than the cumulative price of two separate cables, so the cost is also reduced.

[0026] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, without departing from the technical principles of the present invention, several improvements and modifications can be made, such as designing 6 terminal blocks for the local type II telephone junction box, grouping 3 adjacent rooms, and using 6-core cables for unified wiring, etc. These improvements and modifications should also be regarded as the scope of protection of the present invention.
