Description
Technical Field
The application relates to the technical field of scientific exhibition equipment, in particular to a weighing scale used in scientific exhibition.
Background
The solar system has eight planets, which are water star, golden star, earth, mars, muxing, earth star, king star and sea star in turn according to the distance from the sun from small to large. Due to the different masses and radii of the planets, when a person is on different planets, the weight of the person on different planets can be different due to the difference of the gravitational acceleration on the planets. For example, the gravitational acceleration of the moon is 1/6 for the earth, and the body weight measured on the moon is 1/6 for the earth. There is an urgent need for a scale that enables visitors to experience the weight on other planets in person.
Disclosure of Invention
The application provides a body weight scale for in scientific exhibition can let the visitor experience the weight change on other planets in person.
In order to achieve the purpose, the following technical scheme is adopted in the application:
a weighing scale for scientific exhibition comprises a weighing scale base, a display screen and a control button, wherein the control button and the display screen are arranged above the weighing scale base; the control buttons comprise a selection button and an input button, the input button is used for adding planet information and the ratio of the gravity acceleration of the planet to the gravity acceleration of the earth by a worker, and the selection button is used for selecting a target planet by a tourist; the weight scale is characterized in that a gravity sensor and a controller are installed in the base of the weight scale, a control button, the gravity sensor and a display screen are electrically connected with the controller respectively, the controller is used for calculating the weight of a tourist on a target planet, and the display screen is used for displaying the weight value calculated by the controller.
Furthermore, the display screen is a touch display screen, and the touch display screen is connected above the weighing scale base through a support rod.
Furthermore, the weight scale further comprises a prompting board, the supporting rods comprise a first supporting rod and a second supporting rod, the touch display screen is installed above the weight scale base through the first supporting rod, the prompting board is connected with the first supporting rod through the second supporting rod and located beside the touch display screen, and the prompting board is used for displaying the operation method of the weight scale.
The beneficial effect of this application is:
1) according to the weighing scale, after a tourist stands on the weighing scale base, the corresponding planet can be selected through the control button, the controller in the weighing scale base converts the measured weight into the weight on the target planet, the tourist can experience weight change in person, and compared with the conventional understanding mode that the tourist can only see videos, the weighing scale enables the tourist to participate in the learning mode, and product experience is improved;
2) the touch display screen can be operated, and can also play videos, so that tourists can know the principle that the weights of people on different stars are inconsistent, and the like, and the popular science effect is enhanced.

Detailed Description
The present invention will be described in further detail with reference to the following detailed description and accompanying drawings. Wherein like elements in different embodiments have been given associated element numbers. In the following description, numerous details are set forth in order to provide a better understanding of the present application. However, those skilled in the art will readily recognize that some of the features may be omitted or replaced with other elements, materials, methods in different instances. In some instances, certain operations related to the present application have not been shown or described in detail in order to avoid obscuring the core of the present application from excessive description, and it is not necessary for those skilled in the art to describe these operations in detail, so that they may be fully understood from the description in the specification and the general knowledge in the art.
Furthermore, the features, operations, or characteristics described in the specification may be combined in any suitable manner to form various embodiments. Also, the various steps or actions in the method descriptions may be transposed or transposed in order, as will be apparent to one of ordinary skill in the art. Thus, the various sequences in the specification and drawings are for the purpose of describing certain embodiments only and are not intended to imply a required sequence unless otherwise indicated where such sequence must be followed.
The numbering of the components as such, e.g., "first", "second", etc., is used herein only to distinguish the objects as described, and does not have any sequential or technical meaning. The term "connected" and "coupled" when used in this application, unless otherwise indicated, includes both direct and indirect connections (couplings).
As shown in fig. 1 and 2, the weighing scale for scientific exhibition comprises a weighing scale base 1, a display screen 2 and control buttons 3, wherein the display screen 2 and the control buttons 3 are arranged above the weighing scale base. The control buttons 3 comprise a selection button and an input button, the input button is used for adding information of different stars by staff and the ratio of the gravity acceleration of the star to the gravity acceleration of the earth, and the selection button is used for selecting a target star by a tourist. After the tourist selects the target planet, the tourist stands on the base of the weighing scale to weigh.
A gravity sensor and a controller are installed in the weighing scale base 1, and a control button 3, the gravity sensor and the display screen 2 are electrically connected with the controller respectively. The controller records and stores information of each planet and the ratio of the gravitational acceleration of the planet to the gravitational acceleration of the earth.
The gravity sensor measures pressure signals of the weighed tourists and then transmits the pressure signals to the controller, the controller converts the pressure signals into digital signals, then the weight of the human body on the target planet is calculated according to the ratio of the gravity acceleration of the target planet to the gravity acceleration of the earth, and finally the controller transmits the weight value to the display screen for display. For example, if the gravity sensor measures 392N of a child having a mass of 40kg on the earth and 1/6 of the gravitational acceleration of the moon, the controller converts the measured value into 65.3N of the weight on the moon.
Further, the display screen 2 can be a touch display screen, and the touch display screen is connected above the weighing scale base 1 through a support rod. Some control buttons 3 may be provided in a software system in the touch screen display by which the guest can perform the relevant selection operations. In addition, the touch display screen can also play related science popularization videos, such as video introduction of different weight principles of objects caused by different star balls and different qualities of the star balls.
The scale also includes a notice board 4. The support rods comprise a first support rod 51 and a second support rod 52, the touch display screen is installed above the weighing scale base 1 through the first support rod 51, and the position of the touch display screen is convenient for a tourist to operate and browse. The notice board 4 is connected with the first support rod 51 through the second support rod 52, the notice board 4 is located beside the touch display screen 3, and the notice board 4 prompts the operation method of the weighing machine to the tourists or warns the tourists.
The foregoing is a more detailed description of the present application in connection with specific embodiments thereof, and it is not intended that the present application be limited to the specific embodiments thereof. It will be apparent to those skilled in the art from this disclosure that many more simple derivations or substitutions can be made without departing from the inventive concepts herein.
