Description

Technical Field

[0001] This utility model belongs to the field of instrumentation and metering technology, specifically relating to an electronic instrumentation and metering status identification device and an identification system including the same. Background Technology

[0002] In industrial production and scientific research experiments, the metrological status of instruments directly affects the accuracy and reliability of data. To ensure the accuracy of instrument measurement results, regular metrological calibration is usually required, and metrological markings are affixed to the instruments to visually reflect their calibration status (e.g., qualified, unqualified, or limited use). Metrological markings not only facilitate daily inspections and management but also effectively prevent overuse and reduce data risks caused by instrument inaccuracies.

[0003] Currently, traditional metrological labeling primarily uses paper labels, which are manually affixed to the instrument surface with labels printed with words such as "qualified," "unqualified," and "limited use." This method requires pre-making different types of paper metrological labels for different conditions and replacing them after each calibration. Since paper labels are for single use only and cannot be reused, this results in resource waste. Furthermore, the need to affix labels after each measurement adds extra workload, and the labels are prone to wear, peeling, or fading, affecting long-term use.

[0004] Furthermore, in actual metrological calibration work, some instruments are often installed in high or concealed locations, making it inconvenient to visually identify the calibration date or validity period marked on the metrological label on-site. This makes routine inspections of the instrument status difficult, easily leading to omissions in identifying the instrument's metrological status and causing the instrument to be used beyond its expiration date, thus posing a certain risk to the accuracy of the test data. At the same time, for large and complex systems, after the initial installation and delivery of the instrument, its location is often difficult to locate again, causing difficulties for on-site or in-situ metrological work.

[0032] Example:

[0033] Please see Figure 1 The electronic instrument measurement status indicator device in the preferred embodiment of this utility model includes a housing 1 and a receiving module, a display module 2, a light module 3, a positioning alarm module, and a power supply module disposed within the housing 1. The receiving module is connected to the display module 2, the light module 3, and the positioning alarm module to receive command signals and control the display module 2 to display instrument information, control the light module 3 to display the measurement status and validity period status of the instrument, control the positioning alarm module to issue an audible and visual alarm to indicate the location of the instrument, and provide power to each module through the power supply module.

[0034] Specifically, in the preferred embodiment, the housing 1 has an internal cavity for carrying and accommodating the various structural modules, protecting each structural module, and connecting the electronic instrument measurement status indicator device to the corresponding instrument through the housing 1; at the same time, windows 101 are respectively provided on the housing 1 for the display module 2, the light module 3 and the positioning alarm module to display the display information of each module.

[0035] Preferably, a plurality of mounting holes 8 are provided at intervals on the housing 1, and corresponding mounting holes are also provided on the instrument, so that the housing 1 can be fixed to the instrument by means of a connector passing through the mounting holes 8. Of course, a magnetic component can also be provided on the back of the housing 1, so that the housing 1 can be fixed to the corresponding instrument by magnetic attraction, thereby fixing the marking device to the instrument.

[0036] Furthermore, in the preferred embodiment, the display module 2 is used to display instrument information, such as instrument name, instrument number, etc. Preferably, the window 101 corresponding to the display module 2 is a glass window to protect the display module 2 from accidental scratches.

[0037] Furthermore, in the preferred embodiment, the lighting module 3 includes a first lighting unit and a second lighting unit; wherein the first lighting unit is used to display the metering status of the instrument, and the second lighting unit is used to display the validity period status of the instrument.

[0038] In a specific embodiment of this utility model, the metering status of the instrument includes three states: qualified, unqualified, and limited use. It is understood that a qualified metering status indicates that after verification or calibration, all functions and ranges of the instrument meet the metering requirements and are in a normal usable state; an unqualified metering status indicates that the instrument has a problem and cannot meet the usage requirements, and must be discontinued; a limited use metering status indicates that some functions or ranges of the instrument are suitable for specific conditions, and may be limited in accuracy or partially damaged, requiring use within a limited range.

[0039] Accordingly, a first indicator light is set in the first lighting unit for each metering state of the instrument, and the light colors that can be displayed by each first indicator light may be the same or different.

[0040] like Figure 1 As shown in the preferred embodiment, the first lighting unit is equipped with a qualified indicator light 301, a failed indicator light 302, and a restricted indicator light 303 corresponding to the three metering states of the instrument. The receiving module controls the corresponding indicator light to illuminate based on the received metering state of the instrument. Preferably, each of the first indicator lights displays a different color; for example, the qualified indicator light 301 can display green light, the failed indicator light 302 can display red light, and the restricted indicator light 303 can display yellow light, so that personnel can quickly and intuitively see the metering state of the instrument based on the indicator light color.

[0041] Of course, only one first indicator light can be set in the first lighting unit, which can switch to display different colors of light according to different metering states.

[0042] Preferably, a second indicator light is set in the second lighting unit for each validity period status of the instrument. The second indicator lights can display the same or different light colors, and the administrator can confirm the metering status of the instrument based on the color matching of the lights.

[0043] In the preferred embodiment, the validity period status of the instrument includes both within the validity period and expired, such as... Figure 1 As shown, the second lighting unit is equipped with a valid-expiration indicator light 304 and an expired indicator light 305 corresponding to the two validity periods. When the meter's measurement status is in a certain validity period state, the corresponding indicator light illuminates. Preferably, each of the second indicator lights has a different displayable color. For example, when the meter is in the valid-expiration state, the valid-expiration indicator light 304 illuminates green; when the meter is in the expired state, the expired indicator light 305 illuminates red. This allows administrators to quickly and intuitively see the meter's validity period status based on the indicator light colors.

[0044] More preferably, when the instrument is within its validity period, the valid indicator light 304 remains constantly lit; when the instrument is expired, the expired indicator light 305 flashes to remind the administrator.

[0045] Of course, only one second indicator light can be set in the second lighting unit. This second indicator light can switch to display different colors of light according to the validity status of the instrument. The administrator can confirm the validity status of the instrument by matching the color of the light.

[0046] Preferably, a first button 6 and a second button 7 are also provided on the housing 1. The first button 6 is connected to each first indicator light through a first switching circuit board and is used to manually control the first light unit to switch the metering state. The second button 7 is connected to each second indicator light through a second switching circuit board and is used to manually control the second light unit to switch the expiration state. This allows the metering state and expiration state of the instrument to be switched by manually switching each indicator light on or off using the two buttons.

[0047] Furthermore, the positioning alarm module in this utility model is installed on the housing 1, including a buzzer 4 and a flashing indicator light 5. The buzzer 4 can emit an audible alarm, and the flashing indicator light 5 can emit a flashing light, so as to indicate the position of the instrument by activating the buzzer 4 and the flashing indicator light 5 when needed.

[0048] Furthermore, the power module in this invention is connected to the display module 2, the lighting module 3, the positioning alarm module, and the receiving module respectively, for power supply. Preferably, the power module includes a rechargeable battery, and a charging port 9 is provided corresponding to the charging end of the rechargeable battery; more preferably, the display module 2 can display the power level of the rechargeable battery, so that the administrator can monitor the power level of the rechargeable battery in real time and charge it in a timely manner.

[0049] Furthermore, this utility model also relates to an electronic instrument measurement status identification system, including the aforementioned electronic instrument measurement status identification device, and further including a wireless transmission module and a control terminal. The receiving module is connected to the control terminal through the wireless transmission module so that the control terminal can send instruction signals to the receiving module, thereby controlling the operation of each module of the identification device through the control terminal.

[0050] Specifically, the control terminal includes a remote control terminal and a handheld control terminal. The administrator can edit the display content of the display module 2 through the remote control terminal and remotely set the metering status and validity period status of the corresponding instrument. For example, the administrator can confirm the metering status of the instrument through the verification results, and periodically confirm the validity period status of the instrument through the instrument traceability certificate and metering interval. Then, the administrator can control the corresponding indicator light on the instrument's identification device to light up according to the metering status and validity period status. Of course, the traceability date and metering interval can also be set in the control terminal system. The system can automatically monitor the validity period status of the instrument according to the traceability date and metering interval and control the corresponding indicator light to light up.

[0051] Accordingly, the handheld control terminal is used by the administrator to input instrument information, wirelessly match the corresponding instrument based on the instrument information, and control the positioning alarm module on the corresponding instrument identification device to issue an audible and visual alarm after successful matching, so as to locate the instrument position.

[0052] This utility model discloses an electronic instrument measurement status identification device and an identification system containing it. It has a simple structure, is easy to operate, and can be reused. It displays the measurement status and validity period status conveniently and has high recognizability. It also facilitates instrument positioning, enabling quick instrument location in actual work, more convenient inspection of the instrument's measurement status and instrument calibration, and providing a guarantee for the normal use of the instrument.

[0053] Those skilled in the art will readily understand that the above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
