Abstract

PURPOSE:To facilitate creation of diving trim by calculating in a sight-seeing underwater ship or the like the total weight of a seater and its baggage in every panel of plural quantity supporting two or more chairs and from the result of calculation the total moment front, rear, right, left to be displayed. CONSTITUTION:In a sight-seeing underwater ship, a plural number of rectangular regular size panels 2, respectively setting up a chair 4, are supported to a deck 3 of a cabin 1, partitioned in the front and rear by a water-tight partition, respectively by a plural number of supporting beds 11. Here each supporting bed 11 additionally provides a strain gage 7 detecting weight of a passenger 10 and his baggage on the panel 2, and the detection output signal is input to an arithmetic device 5. And this arithmetic device 5, by integrating a distance between a position of the strain gage 7 and a ship body center line 13, trim center line 14, calculates front rear and right left moment while totalizes the weight and front rear and right left moment to be displayed in a display device 12.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to an automatic moment measurement method for a vehicle.

[Conventional technology]

For example, in sightseeing submarines and the like, it is customary to weigh passengers and their belongings immediately before boarding.

This is because it is important to know the weight of passengers and their baggage and the resulting moment for underwater attitude control in a submersible.

In general, it is necessary to create accurate gwiping trims for ships that dive underwater, but for ships with an unspecified number of passengers on board, such as sightseeing submersibles, passengers and their personal belongings are A longitudinal and lateral moment is generated due to the weight. Therefore, passengers and their baggage are generally weighed, but the reality is that the weighing process itself is not only complicated but also time-consuming, and it is difficult to accurately measure the weight.

Even if passengers and their belongings are weighed just before boarding, it is difficult to know the position of the passengers and their belongings inside the ship, so the moment of trim etc. is unknown.

[Problem to be solved by the invention]

The present invention has been proposed in view of the above circumstances, and it calculates and displays the weight of passengers and their belongings and the resulting longitudinal and lateral moments without giving passengers a sense of inconvenience or time constraints. The purpose of the present invention is to provide an automatic moment measurement method for a vehicle that creates a diving trim manually or automatically by a pilot.

[Means to solve the problem]

To this end, the present invention introduces the outputs of strain gauges attached to a plurality of panels supporting each chair in a vehicle equipped with a plurality of chairs into a computing machine, and in the computing machine, The present invention is characterized in that the total weight of the seated person and their belongings is calculated, and the total longitudinal moment and total horizontal moment based on the total weight are calculated and displayed.

[Effect]

The weight of passengers and their baggage is detected for each panel by strain gauges attached to the panels on which the chairs on which passengers are seated are installed, and the outputs of these strain gauges are input to a computer, where they are calculated. The total weight and moment are calculated and automatically displayed on the display.

[Example] An example in which the present invention is applied to a sightseeing submarine will be explained with reference to the drawings. Figure 1 is the overall layout, and Figure 2 is the first
FIG. 3 is a partially enlarged view of the seat shown in FIG. 2, and FIG. 4 is a flowchart showing procedures for measuring weight and moment according to the present invention.

First, in FIGS. 1 to 3, on the deck 3 of the cabin 1 whose front and back are partitioned by watertight bulkheads, a plurality of rectangular regular-sized panels 2 are each supported by a plurality of support stands 11, and a chair 4 is mounted on each panel 2. It is erected.

Reference numeral 5 denotes a computer which inputs the output of the strain gauge 7 attached to each support stand 11 via an electric wire 6, and connects the passenger 10 in the manner described later.
and ffi of the personal items 9! and calculate the moment given to the hull.

In such a cabin, passenger 10 is seated on chair 4,
The personal item 9 is placed on the passenger's lap or on the panel 2.

Then, the load applied to the panel 2 is detected by the strain gauge 7 and input to the computer 5 via the electric wire 6.

The computing device 5 calculates the position of the strain gauge 7 and the hull centerline 13 inputted in advance. By integrating the distance with the trim center line 14 (Fig. 1), the longitudinal and lateral moments are calculated as shown in Fig. 4, and the weight and longitudinal and lateral moments are totaled, and this is displayed on the display 12. do.

Based on the values displayed in this way, the biloft can create a diving trim, or the automatic ballast control device 8 can create a diving trim based on the difference from the standard value.

Next, in Fig. 4, each symbol is as follows: W: Total weight of passengers and personal belongings Mi: Total left and right moment Ml: Total longitudinal moment Wi: Weight of passenger and personal belongings for each strain gauge lLt: For each strain gauge A Ti: Distance from the center line of the rim of passengers and belongings for each strain gauge.

The above-mentioned total weight W1 (total left and right moment) M i and longitudinal left moment M are automatically calculated by the calculator 5 and displayed on the display 12 .

〔Effect of the invention〕

According to such a method, it is possible to accurately grasp the weight of passengers and their belongings, and the resulting longitudinal and lateral moments, which have been difficult to grasp in the past, without bothering the passengers in the slightest. can facilitate the creation of diving trims.

As a result, the pilot's work is reduced and the time required to dive is shortened.

INDUSTRIAL APPLICABILITY The present invention can be widely used in vehicles that require guiping trim, such as submarines and aircraft.

In short, according to the present invention, in a vehicle in which a plurality of chairs are arranged, the outputs of strain gauges attached to a plurality of panels supporting each chair are introduced into a computing machine, and in the computing machine, each of the panels In addition to calculating the total weight of the seated passengers and their belongings, the front and rear edge moments and total left and right moments based on the total weight are also calculated and displayed. The present invention provides an automatic moment measurement method for a vehicle that calculates and displays the weight of passengers and belongings and the resulting longitudinal and lateral moments without physical constraints, and creates diving trims manually or automatically by the pilot. It is extremely useful.
