[0026] In order to make the purpose, characteristics and advantages of the utility model more obvious and easy to understand, the technical scheme of the utility model will be described clearly and completely in combination with the drawings in the specific embodiments. Obviously, the embodiments described below are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the patent, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the patent.

[0027] As shown in Figure 1 and Figure 2 The sealed test paper collecting device for test paper provided by the utility model comprises a base 1, and the bottom of the base 1 can be provided with a suction cup for convenient fixation.

[0028] A weighing device 2 is installed on the base 1, and the upper end of the weighing device 2 is provided with a test paper tray 3. The test paper tray 3 is provided with a hollow part at one end, and the base 1 at the bottom of the hollow part is provided with an RFID identification module 5. The RFID identification module 5 can identify the RFID barcode information of the test paper bag and the RFID barcode information on the test paper.

[0029] In the embodiment, a single-chip microcomputer 6, a weighing sensing module 7 and a signal processing module 8 are arranged in the weighing device 2.

[0030] Optionally, the weighing sensing module 7 adopts an L-611RD weighing sensing module, or a ZL601 weighing sensing module or a YZC-133 weighing sensing module. The single-chip microcomputer 6 adopts an STM32F051C8T6 single-chip microcomputer or a TMS32OC6455 single-chip microcomputer.

[0031] In order to conveniently display the weight information of the test paper bag, a display screen 9 and control buttons are arranged on the weighing device 2. The single-chip microcomputer 6 is connected with the weighing sensing module 7 through the signal processing module 8 to acquire the weight information of the test paper bag placed on the test paper tray 3. The single-chip microcomputer 6 is connected with the RFID identification module 5 to acquire the RFID barcode information of the test paper bag and is connected with the display screen 9 to display the weight information and the RFID barcode information of the test paper bag.

[0032] In the embodiment, a voice alarm is installed on the weighing device 2. The single-chip microcomputer 6 is connected with the voice alarm through a signal amplification module.

[0033] In order to acquire the information on the upper surface of the test paper bag, a supporting seat 10 is further installed on the base 1. The supporting seat 10 is fixedly connected with a sleeve rod 11, and the sleeve rod 11 is slidingly connected with a lifting rod 4, so that the device is convenient to store, carry and store.

[0034] The end of the lifting rod is connected with a straight rod 12, which is connected with the lifting rod 4 in a hinged manner. The end of the straight rod 12 is provided with a camera 13; the camera 13 is in communication connection with the single-chip microcomputer 6. The camera 13 can take information on the upper surface of the test paper bag. Of course, the upper surface of the test paper bag can be provided with a bar code information, or a two-dimensional code and the like, which is identified through the camera 13, so as to identify the information of the test paper bag.

[0035] The embodiment can check the RFID bar code information obtained by the RFID identification module 5 with the information on the upper surface of the test paper bag, so as to ensure the safety of the test paper bag.

[0036] Based on the sealed test paper bag collecting device provided in the embodiment, the working mode is that the sealed test paper bag is placed on the test paper tray 3, the camera 13 above the test paper tray 3 identifies the bar code or two-dimensional code on the surface of the test paper bag, and reads the related information, such as the examination room information, which contains the number of test papers in the test paper bag and other related information.

[0037] After the examination room information is identified, the RFID identification module 5 detects the RFID bar code on each test paper in the test paper bag, reads the examinee information and counts the number of test papers; at the same time, the weighter 2 detects the weight, calculates the number of test papers contained after subtracting the weight of the test paper bag; finally, the number of test papers and the RFID bar code information are displayed on the display screen 9.

[0038] The information related to the embodiment can include but is not limited to the examination room information, the examinee information, the weighing information, the RFID bar code information and the comparison information of the weighing information and the RFID bar code information and the like.

[0039] When the RFID bar code information does not match the weighing information, or the number of test papers measured does not match the number of test papers in the test paper bag, an error warning sound is issued through the voice alarm, and the examinee information of the missing test paper is also reported.

[0040] As a mode of the embodiment, in order to ensure the accuracy of the weighing information sensed by the weighing sensing module and reduce the interference of external information, for example, Figure 3As shown, the signal processing module includes: resistors R1, R2, R3, R4, R5, R6, R7, capacitors C1, C2, C3, and an operational amplifier U1; the first end of the resistor R1 is connected to the input end of the signal processing module, and the second end of the resistor R1 is connected to the first end of the resistor R2, the first end of the resistor R3, and the first end of the capacitor C1. The second end of the capacitor C1 is connected to the first end of the resistor R4 and the first end of the capacitor C2; the second end of the resistor R3, the second end of the resistor R4, the second end of the capacitor C3, the second end of the resistor R6, and the first end of the resistor R5 are grounded; the second end of the capacitor C2 is connected to the second end of the resistor R5, the first end of the resistor R7, and the negative input end of the operational amplifier U1; the positive input end of the operational amplifier U1 is connected to the first end of the resistor R6; the output end of the operational amplifier U1 is connected to the second end of the resistor R2, the second end of the resistor R7, and the output end of the signal processing module; and the operational amplifier U1 is an LM1458 operational amplifier.

[0041] In this embodiment, the weighing sensing module receives a signal through the resistor R1. The capacitor C1, the resistors R1, R2, and R3 constitute a high-pass filter for filtering out low-frequency noise. The capacitor C2 and the resistors R4 and R5 constitute a low-pass filter for filtering out high-frequency noise. The capacitor C3 and the resistor R6 provide an additional low-pass filter path to further reduce high-frequency interference.

[0042] The LM1458 operational amplifier in this embodiment is a differential amplifier, which receives a signal attenuated by R6 at the positive input end and a signal filtered by R5 and C2 at the negative input end. It can amplify the weighing signal and reduce the influence of common-mode noise. The amplified signal is output to the output end through the resistor R7 and also fed back to the output end of the high-pass filter through the resistor R2, forming a negative feedback to stabilize the gain and frequency response of the amplifier. The accuracy and anti-interference ability of the weighing information are effectively improved.
