By dynamically adjusting the display direction and operating logic, the human-machine interaction adaptability of the equipment is improved. Background Technology

[0002] In the field of industrial measurement, mass flow meters, as an important flow measurement instrument, are mainly classified into two types based on the connection between their transmitters and sensors: integrated and separate (e.g., ...). Figure 1 (As shown). In field applications, due to stringent installation conditions and size limitations, mass flow meters often require various installation methods, such as upright mounting, inverted mounting, or flag mounting.

[0003] For split-type mass flow meters, the transmitter can be connected via shielded cables, ensuring that the transmitter displays the data in the correct installation orientation, effectively solving the display orientation problem. However, integrated mass flow meters face significant technical challenges. Because the display orientation of the transmitter's content is directly dependent on the installation orientation, the local display orientation of measurement parameters is limited in various installation scenarios, including upright, inverted, and flag-mounted installations, and the convenience of operating the panel's photoelectric buttons is greatly reduced.

[0004] Furthermore, integrated mass flow meters are not only limited by the sensor's manufacturing process and installation dimensions, but the sensor's installation method and display operation are also affected when facing different types of measurement media. This situation severely restricts the application adaptability and operational convenience of integrated mass flow meters in complex working environments, urgently requiring a technical solution that can achieve adaptive display and operation functions under different installation orientations to improve product usability and user experience.

[0040] II. The core technical problem to be solved by the technical solution of this application

[0041] In industrial measurement, mass flow meter transmitters and sensors are connected in two ways: integrated and separate. Separate types allow the transmitter to display normally via shielded cables, but integrated types have significant technical problems: the transmitter display direction is restricted by the installation orientation. In upright, inverted, or flag-mounted installations, the on-site display direction of measurement parameters is limited, significantly reducing the ease of operation of the panel's photoelectric buttons. Furthermore, integrated types are also limited by the sensor's manufacturing dimensions, affecting sensor installation and display operation when facing different measurement media. These issues result in poor adaptability and operational convenience of integrated mass flow meters in complex operating conditions, necessitating a technical solution that enables adaptive display and operation under different installation orientations to improve product usability and user experience.

[0042] III. Based on the above problems, this utility model specifically provides a technical solution to solve these problems. The following describes a specific embodiment with reference to... Figure 2 , Figure 3 As shown, the technical solution, working principle and technical effects of this utility model are described in detail.

[0043] Example 1

[0044] refer to Figure 2 and Figure 3 The adaptive display transmitter of this utility model includes a motion monitoring sensor module, a control chip, an OLED display screen, and a photoelectric button group.

[0045] The motion monitoring sensor module uses a MEMS gyroscope, which is integrated into the transmitter hardware circuit to detect the motion state and acceleration changes of the equipment's X, Y, and Z axes in real time.

[0046] The control chip is a C8051 microcontroller, which connects to the gyroscope via I2C communication to acquire and analyze motion data.

[0047] The OLED display has a 128×128 dot matrix and a symmetrical structure. It is installed on the front of the transmitter, and its display orientation can be dynamically adjusted according to the control chip's instructions.

[0048] The photoelectric keypad group includes four sets of keys: confirm key / left key, increment key, decrement key / return key, and page up key / right key, which are symmetrically distributed in the four directions of the display screen (up, down, left, and right) and connected to the I / O port of the control chip through pull-up resistors.

[0049] When the transmitter's installation orientation changes (e.g., upright, inverted, or flag-mounted), the MEMS gyroscope detects the changes in three-axis acceleration in real time and transmits the data to the C8051 microcontroller via I2C. The microcontroller performs attitude calculations on the motion state, identifies the current installation orientation (e.g., 0°, 90°, 180°, 270°), and dynamically adjusts the display orientation of the OLED screen based on the calculation results to ensure that the displayed content is always upright and visible.

[0050] Meanwhile, the control chip updates the key value mapping of the photoelectric buttons through enumeration. For example, when the transmitter is inverted, the logic of the buttons below will be mapped to the function of the buttons above, keeping the operation logic consistent. The display screen communicates with the control chip via the SPI interface. After receiving the orientation adjustment command, it rearranges the display content in a symmetrical 128×128 dot matrix structure to avoid scaling or stretching.

[0051] Compared with existing integrated mass flow meters, the transmitter in this embodiment solves the problem of limited display direction under inverted and flag-mounted installation by linking the gyroscope and the control chip, which significantly improves the convenience of local display of measurement parameters and panel operation.

[0052] This application uses a 128×128 symmetrical dot matrix OLED display to ensure the consistency of the displayed content under different orientations, while four sets of symmetrically distributed photoelectric buttons, combined with dynamic key value mapping, realize the uniformity of the operating logic under any installation posture, greatly improving the product's adaptability under complex working conditions.

[0053] Example 2

[0054] The difference between this embodiment and Embodiment 1 is that the motion monitoring sensor module uses a combination of an accelerometer and a light sensor module. The accelerometer is used to detect three-axis motion, while the light sensor module is installed on the edge of the display screen to detect ambient light intensity.

[0055] In addition, the display screen has been replaced with an LCD screen, while the dot matrix remains a 128×128 symmetrical structure, communicating with the control chip via an I2C interface. The layout of the photoelectric button group is the same as in Embodiment 1, but the button functions have been enhanced with ambient light sensing triggering logic, such as automatically adjusting button sensitivity in strong light environments.

[0056] In this embodiment, the introduction of a light sensor module allows the transmitter to dynamically adjust the display brightness and button response threshold based on ambient light intensity while detecting the installation posture. When the accelerometer detects a change in posture, the control chip simultaneously processes the illumination data from the light sensor module.

[0057] If the ambient light is strong, the screen brightness will be automatically increased and the button trigger threshold will be lowered to adapt to operation under strong light.

[0058] If the ambient light is low, the brightness is reduced and the button trigger threshold is increased to avoid accidental operation. The LCD screen receives dual instructions (attitude adjustment and brightness adjustment) from the control chip via the I2C interface. First, the display orientation is rotated, and then the backlight brightness is adjusted based on the light sensor data. During button operation, the control chip optimizes the key value mapping algorithm based on the light sensor data. For example, in backlit environments, the button function priority will be temporarily adjusted to ensure operational accuracy.

[0059] This embodiment further expands the transmitter's adaptive capabilities by combining an accelerometer with a light sensor module. It can not only adapt to different installation orientations, but also automatically optimize the display and operating experience based on ambient lighting.

[0060] Compared to Example 1, the LCD display with a light sensor module reduces power consumption and significantly improves operational stability in both strong and low light conditions, making it particularly suitable for outdoor use or environments with frequent changes in lighting. For example, when used in sunlight, the light sensor module triggers high-brightness display and sensitive button response, preventing blurry displays and operational errors caused by glare, further enhancing the product's environmental adaptability and user experience.

[0061] Example 3: Adaptive Display Transmitter with Integrated Light Sensing Module

[0062] Based on Example 1, the motion monitoring sensor module adds a light sensor module, which is connected in parallel with the MEMS gyroscope into the circuit. The light sensor module is used to detect the ambient light intensity, and the display screen can automatically adjust its brightness based on the light sensor data. Its interface is connected to the control chip via I2C.

[0063] When the transmitter's attitude changes, the gyroscope triggers an adjustment to the display orientation. Simultaneously, the light sensor module monitors ambient light in real time. If the light is too strong (e.g., strong outdoor light), the control chip adjusts the OLED display brightness to its maximum level; if the light is insufficient (e.g., indoors), the brightness is reduced to save power. These two mechanisms work together to achieve dual adaptive adjustment of display orientation and brightness.

[0064] This embodiment incorporates a light-sensing module, enabling the transmitter to maintain a clear display under different lighting conditions. For example, the brightness is automatically increased by 2 times under strong outdoor light and the power consumption is reduced by 40% under weak indoor light, further expanding the product's applicable scenarios.

[0065] The above description is only a preferred embodiment of this application and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.

[0066] Furthermore, the technical solutions of the various embodiments can be combined with each other, but only if they are feasible for those skilled in the art. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.
