The embodiments described below by referring to the drawings are exemplary only for explaining the present invention, and should not be construed as limiting the present invention.
The utility model provides an embodiment of the unusual early warning system of online moisture meter of key process of throwing, particularly, as shown in FIG. 1, wherein include: the device comprises an online moisture meter 1 to be tested, a standby online moisture meter 2, a material conveying mechanism 3 (which can be a belt or a vibrating conveyor according to different processes), a timer, an alarm and a data storage module, wherein an input port and an output port of the material conveying mechanism 3 are respectively connected with a feeding roller 100 in the previous process and a device 200 in the next process;
the online moisture meter 1 to be tested is arranged above the material conveying mechanism 3 and is used for participating in control feedback of the original silk making process;
the standby online moisture meter 2 is arranged above the material conveying mechanism 3 and is positioned in front of or behind the online moisture meter to be measured 1 according to the running direction of the material conveying mechanism 3 (the figure shows an example of being positioned behind the moisture meter to be measured); a preset distance is reserved between the online moisture meter 1 to be tested and the standby online moisture meter 2;
the data storage module is used for storing detection data (which can be determined according to the position of the online moisture meter 1 to be detected or the standby online moisture meter 2);
in order to synchronize the detection data of the online moisture meter 1 to be detected and the standby online moisture meter 2, the timer can set the data delay reading time length, that is, the time length can be set so that the detection data of the online moisture meter 1 and the standby online moisture meter are for the same material, and understandably, the setting of the data delay reading time length is related to the preset interval and the running speed of the material conveying mechanism 3. In practical operation, the aforementioned timer can be implemented by using a mode such as an electronic timer, a clock module, a delay relay, etc.
In the connection, it can be understood that, except for the electric signal connection with the online moisture meter 1 to be tested, the standby online moisture meter 2, the timer and the data storage module, the original machine controller is respectively connected with the material conveying mechanism 3 and the alarm through the electric signal connection, and is used for sending a stop signal to the material conveying mechanism 3 and sending a trigger signal to the alarm, so that the alarm outputs early warning information.

The comparison method of the to-be-detected and the standby belongs to a mature technology, for example, but not limited to, the relationship between the numerical deviation of the two and the preset upper and lower deviation thresholds (the corresponding required thresholds can be calculated according to historical data of different brands in advance) can be directly compared, and the relationship between the abnormal deviation frequency and the preset frequency (for example, 5 times, which can be realized by a counting module connected with the original machine controller) is combined, so that an early warning signal can be sent out by an alarm to prompt an online operator to pay attention and check in time. Adopt two modes of verifying with the specification instrument to belong to ripe technique, to this the utility model discloses do not prescribe a limit to, and need point out that another effect of the reserve online moisture meter of design is, if the online moisture meter that awaits measuring appears unusually, then can launch the work that reserve online moisture meter took over the former online moisture meter that awaits measuring, this also provides convenient condition for online production does not shut down, for example through the electric circuit shielding fall unusual former online moisture meter that awaits measuring.
Further, the early warning system may further include a drum rotation speed detection unit electrically connected to the original machine controller, for detecting a rotation speed of the feeding drum 100 in the previous process, where the rotation speed signal may assist in characterizing the aforementioned "stage of normally conveying materials in two processes", for example, detecting that the rotation speed of the drum is increased (for example, the normal state of the sheet drying process is 9 r/min), at this time, the material conveying mechanism is triggered to operate, the materials are conveyed to the next process, and at this time, the moisture data may be collected and subjected to moisture meter verification processing. On the basis of this concept, a first level detector 4 and a second level detector 5 (both preferably infrared distance measuring devices) can also be arranged above the input and output of the material conveying mechanism 3, so that the material conveying mechanism is triggered to stop in a non-moisture meter checking stage according to the state of the roller. The following examples are given here for reference:
the detection signal of the roller rotating speed detection unit represents that the roller rotating speed ratio is low (if the roller rotating speed ratio is at or below 6 r/min), at the moment, the first material level detector and the second material level detector detect that the height of the material is at a certain set limiting value or the height change does not exceed a certain set specified value, and at the moment, the original machine controller can trigger the material conveying mechanism to stop running; or the detection signal of the roller rotating speed detection unit indicates that the roller is in a 'material pouring' state, namely the rotating speed of the roller is relatively too high (for example, at or above 15 r/min), and the material height detected by the second material level detector reaches a low limit, so that the conveying stop is triggered.
It should be noted here that, in consideration of triggering the material transportation stop, not only for saving energy, but also for checking the online moisture meter to be tested from another angle, that is, once the material transportation mechanism is triggered to stop, if the fluctuation of the indication value of the online moisture meter to be tested is detected at this stage, the abnormality of the moisture meter is also indicated, and the alarm can be triggered to prompt the relevant personnel to pay attention.
Finally, it can also be supplemented that, in some preferred embodiments, the early warning system further includes a trigger button electrically connected to the original machine controller, and the trigger button can be used as a trigger mechanism for starting and stopping the functions of the system, for example, in a workshop, the device is in an equipment maintenance or maintenance state, and is not suitable for on-line moisture meter calibration processing, and may trigger an alarm by mistake to output an early warning signal, so that the trigger button can be operated to cut off the corresponding detection early warning function; on the contrary, when the moisture meter needs to be checked online, the trigger button can be operated to start the functions.
With regard to the foregoing mechanism for storing detection data, a specific example is given here for explanation: according to the installation positions of the online moisture meter to be detected and the standby online moisture meter relative to the material conveying direction, only the detection data with the front relative position can be stored. For example, only the detection data of the moisture meter at the front position needs to be stored, and after the data is detected by the moisture meter at the back position, the detection data of the moisture meter at the front position is read from the storage module according to the set delay reading duration, and compared with the current detection data of the moisture meter at the back position to complete the verification.
