[0022] In this application, unless otherwise specified or limited, the term "connection" should be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection or an indirect connection through an intermediate medium. In addition, the term "coupling" can be a way of achieving electrical connection for signal transmission.
[0023] As used herein, "about," "substantially," or "approximately" includes the stated value and an average value that is within an acceptable range of variation from the particular value as determined by one of ordinary skill in the art taking into account the measurements in question and the errors associated with the measurement of the particular quantity (i.e., the limitations of the measurement system).
[0024] A flaw detector generally refers to a device that uses non-destructive testing methods such as radiation to detect various macroscopic defects inside or on the surface of materials, objects or equipment and determine their location, size, shape and type without damaging the performance of the inspected object through the interaction of sound, light, heat, electricity, magnetism and radiation with matter.
[0025] The flaw detector can detect extremely fine cracks, hairlines, white spots, folds, inclusions and other defects on the surface of materials. It has high detection sensitivity and can intuitively display the location, shape, size and severity of defects. It has good repeatability in defect inspection. It has been widely used in the flaw detection of pipes, bars, profiles, welded parts, machined parts, and forgings, especially in the regular inspection of pressure vessels and bearings.
[0026] However, based on the operating principle of the flaw detector, the rays used during the operation of the flaw detector may cause radiation accidents. Therefore, it is urgent to monitor the radiation dose during the operation of the flaw detector.
[0027] The present application provides a multifunctional positioning tracker for a flaw detector, so as to improve the technical problem in the related art that the radiation dose during the operation of the flaw detector is likely to cause radiation accidents.
[0028] The positioning tracker is applied to a flaw detector and includes a processing module 100, a radiation dose detection module 200, a positioning module 300, a vibration sensing module 400, a radio frequency module 500, an adsorption module 600, a communication module 700, a rechargeable battery 800 and an anti-disassembly module 90.
[0029] The processing module 100 includes a microprocessor. The microprocessor serves as a data processing and control center and is connected to the radiation dose detection module 200, the positioning module 300, the rechargeable battery 800 module, the anti-disassembly module 900, the radio frequency module 500, the vibration sensing module 400 and the wireless communication module 700 respectively. In some examples, the main parts of the above modules are integrated on an electronic circuit board. The microprocessor can be used for algorithm operation, logic control, parameter setting of each module, and data uploading of the positioning tracker. The microprocessor can adopt an STM32 series processor. It can be understood that the present application does not limit the model of the microprocessor, and those skilled in the art can choose according to their needs.
[0030] The radiation dose detection module 200 is used to detect the radiation dose of the radioactive material in the flaw detector environment. The processing module 100 is electrically connected to the radiation dose detection module 200 , and the processing module 100 is used to sample the radiation dose.
[0031] The radiation dose detection module 200 includes a silicon PIN photodiode, an amplifier circuit, and a data processing unit. The silicon PIN photodiode is used to generate charges. The amplifier circuit collects and amplifies the charges to form pulses. The count rate of the pulses is proportional to the dose rate, which can be converted to the actual dose rate by comparing the scale. The data processing unit is used to convert the pulse count into a radiation dose. Exemplarily, the radiation dose detection module 200 uses a silicon PIN photodiode as a dose rate sensor. The rays generate ionization in the sensitive volume of the silicon PIN, and the charges are collected and amplified to form pulses through a preamplifier circuit. The count rate of the pulses is proportional to the dose rate, which can be converted to the actual dose rate by comparing the scale. The radiation dose detector is a conventional technical means used by those skilled in the art, and this application will not be elaborated here.
[0032] In this way, the radiation dose detection module 200 provided in the present application can detect the radiation dose of radioactive substances in the flaw detector environment to ensure the safety of the operator.
[0033] The positioning module 300 is electrically connected to the processing module 100 . The positioning module 300 is used to obtain the location information of the positioning tracker and send the positioning data to the processing module 100 .
[0034] The communication module 700 is electrically connected to the processing module 100 , and is also electrically connected to the positioning module 300 . The communication module 700 is used to transmit data in the processing module 100 and the positioning module 300 .
[0035] For example, the positioning module 300 and the wireless communication module 700 use the EC800 wireless communication module 700, which has built-in 4G and GNSS antennas, supports data connections such as LTE-FDD and LTE-TDD, and also supports GNSS positioning functions, and has GPS, BDS, GLONASS, Galileo, QZSS hybrid positioning capabilities.
[0036] The anti-disassembly module 900 is electrically connected to the processing module 100 , and the anti-disassembly module 900 is used to send a disassembly signal to the processing module 100 when the positioning tracker is disassembled.
[0037] The anti-disassembly module 900 includes a photosensitive element and / or a magnetic switch. When the photosensitive element receives light or the magnetic switch is disconnected, the anti-disassembly module 900 determines that the positioning tracker is disassembled.
[0038] Exemplarily, the anti-disassembly module 900 may further include a buzzer and an indicator light. When the processing module 100 receives a disassembly signal, the processing module 100 controls the buzzer and the indicator light to issue a reminder and reports an abnormal state through the communication module 700 .
[0039] For example, the anti-disassembly module 900 determines whether the positioning tracker is being dismantled by means of a photosensitive element and a magnetic switch. When the photosensitive element receives light or the magnetic switch is disconnected, it is determined that the positioning tracker has been dismantled. At this time, a reminder is issued through a buzzer and an indicator light, and an abnormal state is reported. This function can be remotely disabled and enabled through the processing module 100.
[0040] The RF module 500 is electrically connected to the processing module 100. The RF module 500 is used for communication between the processing module 100 and an external device so that the external device can obtain data information of the positioning tracker.
[0041] In some examples, the RF module 500 uses LXMS33HCNG-134 with a size of 3.2×3.2×0.7mm, operates at 13.56MHz, HF band, is compatible with ISO 15693 / NFC Forum Type5 protocol, and has a reading distance of 20mm. The RFID is attached to the inside of the device plastic shell, and its UID information is printed on a sticker in the form of a QR code and attached to the surface of the plastic shell and the flaw detector. This makes it easy for users to read the relevant data of the positioning tracker on site.
[0042] The positioning tracker is provided with a housing 10, and the adsorption module 600 and the modules in the above embodiments are installed in the housing 10 of the positioning tracker. The adsorption module 600 includes a magnet for magnetically connecting with the flaw detector by magnetic adsorption so as to install the positioning tracker on the flaw detector.
[0043] The vibration sensing module 400 is electrically connected to the processing module 100, and is used to detect the vibration of the positioning tracker to detect the movement state of the positioning tracker. The selection of the vibration sensing module 400 model can be determined based on the needs of those skilled in the art. The device is a conventional device and is not described in detail in this application.
[0044] For example, the vibration sensing module 400 uses a vibration sensor to detect whether the device is in a moving state. When the device is moving or registered for use, the position and dose rate data can be reported every 10 minutes. At the same time, the reporting cycle can be remotely modified through the processing module 100. When the device is registered and in a stationary state, it will enter a low-power standby state until it is awakened by the vibration sensor.
[0045] The rechargeable battery 800 module uses explosion-proof polymer lithium batteries. When the battery power is too low, it can be set to enter the Shipping mode to avoid battery failure caused by excessive discharge, and upload the low battery information to the remote server.
[0046] Working example: The processing module 100 can regularly sample the radiation dose detection data detected by the radiation dose detection module 200 and the GPS positioning data of the positioning module 300, and send them to the server through the communication module 700 in real time. The processing module 100 can also interact with the rechargeable battery 800 module to obtain the charging and discharging status data of the positioning tracker, and prompt the user when the battery is low. The processing module 100 can also collect the status data of the anti-disassembly module 900, and when the positioning tracker is removed, a reminder is issued through the buzzer and indicator light. The processing module 100 can also read and write data with the radio frequency module 500, and can update the real-time data in the radio frequency block. The processing module 100 can also collect the status data of the vibration sensing module 400, and detect whether the device is in a mobile state based on the vibration sensor. If it is in a mobile state or a registered use state, radiation and positioning data detection and upload are performed, otherwise the positioning tracker is in a low-power standby state.
