Separate spirit level

The invention is a separate level, in particular, wherein the main sensing unit and the control and display unit are separated from each other, and the control and display unit can receive the measurement result of the sensing unit, and the sensing unit can be placed on the A level device on a plane to be tested in a variety of states.

A level is an important measuring instrument used in industrial engineering or architectural design. The function of the level is to measure and test the horizontal tilt of a particular plane or a plane to be measured, including its tilt. Direction and angle. The level can be in many forms depending on the field of application or the practicality and accuracy, such as the traditional bubble level, digital electronic level, laser optical level, etc., and basically the principle of the level is to obtain a test The degree of inclination of the plane with respect to a reference plane, that is, the orthogonal vertical state between the two planes, can be known that the two planes are parallel to each other or have an inclination in angle and direction.

As far as the current technology is concerned, the level meter can be measured in two measurement modes, one of which is an absolute mode, that is, the reference plane is perpendicular to the direction of gravity, that is, the normal direction of the reference plane is the direction of gravity. Parallel to each other; the other is the relative mode, ie the datum plane used It is a reference plane defined by the user. Regardless of which mode, depending on the requirements of different conditions in engineering or design, it has important applicability, so that the user can know the building body or the plane to be tested relative to a reference plane by the measurement result of the level meter. The degree of horizontalness or degree of inclination allows further adjustment or construction of the desired building.

As far as the current electronic level is concerned, the system is designed to include a sensing unit, a control unit and a display unit in a main body structure, that is, to integrate all the functional units into the same main body structure. And in the measurement, it is necessary to place the main body of the main body on a plane to be measured, and the sensing unit thereof measures the inclination degree of the plane to be measured. In addition to providing the operation interface of the user on the control unit and the display unit, the corresponding data measurement result can be viewed by the set display screen.

However, when the user operates such a level, the measurement result of the sensing unit is often disturbed by the pressing of the touch or the vibration caused by the operation, thereby making the measurement correctness affected; Because the overall device structure is designed to include functional units such as sensing, control and display, the overall device is relatively large in size and heavy in weight, so that some of the tested structures are inherently less rigid. In the case of the situation, it is easy to be deformed due to the weight of the load level; in addition, for some planes to be measured with a small measurement area, or the plane to be tested itself has obstacles such as protruding or concave state of the surface. At the time, the process of placement, operation, and measurement is greatly limited. Therefore, how to solve this problem is the main purpose of the development of this case.

It is an object of the present invention to provide a separate level, and is designed to separate one of the sensing units and one of the control and display units from each other so that the smaller sensing unit can be placed. The measurement of the degree of tilt is performed on the plane to be measured in a plurality of states. At the same time, the measurement can also use the signal transmission mode, the control signal is transmitted by the control and display unit, and then the measurement result of the sensing unit is transmitted back to the control and display unit for display to provide use. Monitoring.

The invention is a separate level meter, which is applied to the measurement of the inclination degree of a plane to be tested. The separation level meter comprises: a sensing unit for placing on the plane to be tested, and measuring the energy The degree of inclination of the plane to be tested; and a control and display unit, the signal is connected to the sensing unit, but the sensing unit is a different entity separately arranged to provide a user control signal to send a control signal The sensing unit can be measured according to the control signal, and the control and display unit can further receive the measurement result of the sensing unit and display the result.

Please refer to the first figure, which is a schematic diagram of the separate level 1 of the present invention. As shown, the split level 1 includes a sensing unit 20 and a control and display unit 10, while the overall design of the sensing unit 20 and the control and display unit 10 are separate entities. and The structures are arranged separately from one another and the transmission of signals or data can be accomplished in a signaled manner for operational control and measurement. In addition, in a preferred embodiment, the control and display unit 10 can be designed as a computer with a functional software, a portable assistant (PDA), and a portable electronic device of a mobile phone, wherein the functional software is It is designed to operate the control and display unit 10 with a human interface function to provide the user with the control and measurement associated with the present invention, and in turn to display corresponding results.

In a preferred embodiment, the signal transmission mode can be transmitted by means of a wireless signal or a wired signal, that is, each of the sensing unit 20 and the control and display unit 10 is designed to have a wireless or wired transmission. interface. As shown, a wired transmission interface 100 on the control and display unit 10 and a wired transmission interface 200 on the sensing unit 20 employ a universal serial bus (USB) specification, if wired in operation. In the transmission mode of the signal, a transmission line (for example, a transmission line of USB specification) can be reused to connect the transmission interfaces 100 and 200, so that the control and display unit 10 and the sensing unit 20 can complete the signal connection. In addition, the transmission of wired signals may also use other communication protocol transmission specifications, such as parallel port or RS-232 serial port.

On the other hand, a wireless transmission interface (not shown) capable of wireless signal transmission may be disposed in the control unit 10 and the sensing unit 20, and the wireless transmission interface may be The signal connection between the control and display unit 10 and the sensing unit 20 is accomplished using specifications such as radio frequency (RF), Bluetooth transmission, or infrared communication protocols. And when In order to use the transmission mode of the wireless signal, the transmitter of one of the transmission interfaces can be used to transmit signals and be received by the receiver of the other transmission interface, so that the operation control and measurement can be performed.

As described above, since the sensing unit 20 and the control and display unit 10 are separated from each other, the volume of the sensing unit 20 can be designed to be small, or it is not occupied when the measurement is performed. A large area, and a preferred embodiment is capable of designing its overall weight of only about 40 grams and designing it as a square shape as shown in the first figure, such that it is in a plane to be tested (not shown). When placing and measuring, it is not impossible to measure due to the limited area that the plane to be tested may exhibit or the adverse factors that are limited by the space conditions, such as the plane of the bump. In other words, the split level meter 1 of the present invention only needs to place the sensing unit 20 therein on the plane to be tested, and the control and display unit 10 that is signally connected to the sensing unit 20 is It can be operated or monitored by the user in accordance with its signal transmission capability, for example, within the wireless transmission range or within the extended length of the transmission line, by the user or placed on another plane.

Please refer to the second figures (a) and (b) for the side and bottom surfaces of the sensing unit 20. Since the sensing unit 20 needs to be placed on the plane to be tested, we design the bottom surface of the sensing unit 20 to have a multi-functional placement condition, so that the placement of the plane to be tested can be completed. As shown in the side view and the bottom view, the bottom surface of the sensing unit 20 has three bump legs 201 to 203 of the same condition, and the plane to be tested presents a smoother or more spacious state. When the bump legs 201~203 are directly contacted with the plane to be tested, the placement is completed. For better implementation In the manner, the bump legs 201-203 are designed to be arc-shaped and have a height of 1.0 mm. In addition, three screw holes 211 to 213 are further included on the bottom surface of the sensing unit 20, and three lengths of the extension legs 221 to 223 (not shown in the figure) can be assembled, thereby enhancing the feeling. The bottom surface of the measuring unit 20, that is, the distance between the bottom surface of the sensing unit 20 and the plane to be tested, can be erected on the plane to be tested.

Please refer to the third figure (a) and (b), which are schematic diagrams showing the straight state of one of the lengthening legs 221 and a curved state; in the present invention, the lengthening legs 221 to 223 are two-stage type. The flexible structure, and the user can bend the respective two-stage structure to adjust an angle A, and the angle A can be an angular range within an angular range (for example, less than 90 degrees), and thus can be viewed from the third figure. (a) The straightening state is changed and adjusted to become a curved state as shown in the third diagram (b). At the same time, the screw holes 211 213 213 are concave spiral spiral seat structures, and one end of the extended legs 221 223 223 is designed corresponding to the screw holes 211 213 213 and 213 The extended legs 221 to 223 can be assembled on the screw holes 211 to 213. The detailed assembly diagram is as follows.

As described above, please refer to the fourth figures (a) to (c), which are schematic diagrams of various mountings after the lengthening legs 221 to 223 are assembled on the bottom surface of the sensing unit 20; Since the lengthening legs 221 to 223 have various angles of bending variation, thereby being able to adapt to different measurement environments on any plane to be tested, for example, in the fourth figure (a), the lengthening legs can be extended. 221~223 are bent outwards, so that the bottom surface of the sensing unit 20 can be raised to avoid the protruding structure on the plane to be tested; or as shown in the fourth figure (b), Extending the lengthening legs 221 to 223 vertically so as to be able to be mounted on a plane to be tested which exhibits a vertical depression or a small area; or as shown in the fourth diagram (c), the lengthening legs can be extended 221~223 are bent inward to raise the bottom surface of the sensing unit 20, so that the erection can be completed on a plane to be tested with a small area or a slanting depression.

Further, by the change of the erection state of the extended legs 221 to 223, we can perform the placement on the plane to be tested of various sizes or on a plane having a special obstacle environment, and further enable The measurement of the degree of tilt. However, when we adopt this erection method, we must perform a calibration procedure on the sensing unit 20 after the extension legs 221 to 223 are fixed and placed to ensure the correctness of the measurement results. In a preferred embodiment, the number of the elongated legs 221-223 used is preferably three of the same length and has the same length; however, for the length, number or length of the elongated legs used The choice of materials, etc., can also be completed by other configuration requirements.

Please refer to the fifth figure, which is a schematic diagram of the axial correspondence between the sensing unit 20 and the control and display unit 10. The control level and display unit 10 of the present invention further includes a liquid crystal screen 11 and an operation interface 12 for providing a user with a measurement process of the sensing unit 20. The operation control is performed, and the liquid crystal screen 11 is used to display the measurement result. The user can send a control signal (which can be wired or wireless signal transmission) by controlling the operation interface 12, and the sensing unit 20 performs measurement according to the control signal; and when the sensing unit 20 When measuring the inclination of a plane to be measured, it will The result is simultaneously transmitted back to the control and display unit 10 for reception, and the data can be displayed on the liquid crystal screen 11.

As described above, the definition and correspondence between the plane and the axial direction set between the two are measured by using the sensing unit 20 and an indication of the respective designs on the surface of the control and display unit 10. Marks 101, 23 are used to indicate the corresponding directions. As shown in the fifth figure, the preferred embodiment is that the indicator marks 101 and 23 are all designed as a triangular symbol, and when the directions indicated by the triangular symbols are in the same direction, the control and the control are represented. The display unit 10 and the sensing unit 20 are defined on the same XY plane, that is, for the case where the definitions of the directions of the respective X-axis and Y-axis are consistent.

As shown in the sixth figure, it is a schematic diagram of the tilt measurement result; as described above, the display mode of the liquid crystal screen 11 defines four quadrants I, II, III, and IV in the XY plane. And a tilting direction pointer 13 indicates that a highest point of the plane to be measured is located, that is, the measurement of the degree of tilt of the sensing unit 20 on the plane to be measured, and the gradient direction is indicated relative to The reference plane is the place where the change is the greatest, and is indicated by the tilt direction pointer 13. The schematic diagram in the sixth figure illustrates that the direction indicated by the tilt direction pointer 13 is directed to the first quadrant I, that is, the plane to be tested placed by the sensing unit 20 is indicated by the indicator mark 23 The right front side is inclined to the left rear side, that is, the plane to be measured is inclined from the first quadrant I to the third quadrant III in the displayed XY plane; in other words, the highest point of the plane to be tested relative to a certain reference plane It is in the first quadrant I and the lowest point is in the third quadrant III.

The change in the tilt angle on the X-axis and the Y-axis is also displayed on the liquid crystal screen 11. It is worth noting that as the tilting state or the tilting direction of the plane to be measured is different, the tilt angle changes on the X-axis and the Y-axis also have representations of the sign values corresponding to different quadrants. The two angles in the sixth figure are all shown as positive 10 degrees, which means that the highest point is in the first quadrant I. In other cases, under the design and definition, when the highest point is in the second quadrant II, the value of the X-axis axis is displayed as a negative sign and the value of the Y-direction axis is displayed as a positive sign; when the highest point is at the In the four quadrant IV, the value of the X direction axis is displayed as a positive sign and the value of the Y direction axis is displayed as a negative sign; and when the highest point is in the third quadrant III, the values of the X direction axis and the Y direction axis are displayed. It is a negative sign. In addition, if the plane to be measured exhibits no tilt with respect to the reference plane, the tilt direction pointer 13 disappears, and the value of the tilt angle on the X-axis and the Y-axis is 0.0 degrees. ±0.1 degrees (including 0.1 degrees).
