DETAILED DESCRIPTION
[0026] The following embodiments of the technical solution of the present invention will be described in detail with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention and are therefore only examples and are not intended to limit the scope of protection of the present invention.
[0027] It should be noted that, unless otherwise specified, the technical or scientific terms used in this application should have the common meanings understood by those skilled in the art to which the present invention belongs.
[0028] In the description of this application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like to indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.
[0029] In addition, the terms "first," "second," etc. are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the technical features indicated. In the description of the present invention, "plurality" means more than two, unless otherwise specifically defined.
[0030] In this application, unless otherwise expressly specified or limited, terms such as "mounted," "connected," "connect," and "fixed" should be understood in a broad sense. For example, they may refer to fixed or detachable connections, or integration; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on specific circumstances.
[0031] In this application, unless otherwise expressly specified or limited, when a first feature is "above" or "below" a second feature, it may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Furthermore, when a first feature is "above," "above," or "above" a second feature, it may mean that the first feature is directly above or diagonally above the second feature, or simply means that the first feature is at a higher level than the second feature. When a first feature is "below," "below," or "below" a second feature, it may mean that the first feature is directly below or diagonally below the second feature, or simply means that the first feature is at a lower level than the second feature.
[0032] The scale status monitoring device described in this embodiment is primarily used to monitor the status of an electronic floor scale. The proper operation and accurate measurement of an electronic floor scale are affected by ambient temperature and humidity. Temperature fluctuations can cause differences in the thermal expansion coefficient and thermal stability of internal components, which in turn affects the accuracy and stability of the scale. Therefore, monitoring the ambient temperature is crucial to ensure the accuracy and reliability of the scale.
[0033] At the same time, maintaining an appropriate humidity range is crucial for the stable operation of a scale. Both excessively high and low humidity levels can adversely affect the scale. Excessively high humidity can cause equipment leakage, oxidation, rust, and other issues, while excessively low humidity can generate static electricity, affecting the scale's accuracy and stability. Therefore, it is crucial to monitor the humidity around the scale to ensure it remains within an appropriate range. To minimize the effects of humidity on the scale, appropriate precautions should be taken, such as maintaining good ventilation around the scale, avoiding direct water sources, and using dehumidification equipment when necessary to maintain an appropriate humidity environment.
[0034] In summary, during the use and maintenance of the floor scale, monitoring and controlling the ambient temperature and humidity are important links to ensure its accuracy and reliability.
[0035] like Figure 1 and Figure 2As shown, the present invention provides a weighing instrument status monitoring device, comprising a control module and a temperature monitoring module, a humidity monitoring module, a tilt sensor module, and a displacement sensor module connected to the control module. The temperature monitoring module is disposed in a sensor for collecting on-site temperature data and sending the temperature data to the control module; the humidity monitoring module is disposed in a sensor for collecting on-site humidity data and sending the humidity data to the control module; the tilt sensor module is disposed in a sensor for collecting the tilt angle of the weighing instrument and sending the tilt angle to the control module; the displacement sensor module is disposed on the weighing platform of the weighing instrument for collecting the displacement distance of the weighing instrument and sending the displacement distance to the control module. The control module is configured to send the temperature data, humidity data, tilt angle, and displacement distance to a monitoring terminal via a signal line.
[0036] In this embodiment, the monitoring terminal can be a mobile smart terminal or a PC. When the temperature and humidity data collected at the scene, the tilt angle or displacement distance of the scale exceeds the set threshold, the monitoring terminal can promptly issue a prompt to the management personnel so that the management personnel can take measures as soon as possible.
[0037] In this embodiment, the displacement distance of the scale includes the front-to-back displacement distance and the left-to-right displacement distance. After a scale is used for a long time, the tilt angle of the scale platform may be erroneous, which may affect the accuracy and reliability of the scale. Therefore, it is necessary to monitor the tilt angle of the scale platform through a tilt sensor module.
[0038] In this embodiment, the temperature monitoring module may be a PT100 temperature acquisition module, the humidity monitoring module may be an SHT30 humidity acquisition module, the tilt sensor module may be a dual-axis RS232 tilt sensor, and the displacement sensor module may be an LDM1000 displacement sensor.
[0039] In this embodiment, the control module may be a single chip microcomputer or a PLC controller.
[0040] In summary, the scale status monitoring device provided by the present invention collects on-site temperature data through the temperature monitoring module, collects on-site humidity data through the humidity monitoring module, collects the inclination angle of the scale through the inclination sensor module, collects the displacement distance of the scale through the displacement sensor module, and sends the temperature data, humidity data, inclination angle and displacement distance to the monitoring terminal through the signal line, so that the management personnel can monitor the status and working environment of the scale in real time to avoid affecting the accuracy and reliability of the floor scale.
[0041] Finally, it should be noted that the various technical features of the technical solution of this application can be combined arbitrarily. In order to make the description concise, not all possible combinations of the various technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this application.
[0042] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or make equivalent replacements for some or all of the technical features therein.
