Description

Technical Field

[0001] This utility model relates to the field of detector technology, and in particular to an encrypted detector device. Background Technology

[0002] The detector device is a radiation measurement device used in industrial inspection to measure the level of molten steel. Traditional detector devices typically use a photomultiplier tube to emit pulse signals, which are then processed by a shaping circuit and transmitted as analog signals to the receiving module via cable.

[0003] However, due to the typically long transmission distances of tens of meters, analog signals are prone to attenuation during transmission, and external interference has a significant impact on the signal, causing excessive fluctuations in the received signal and severely affecting the accuracy and stability of the detection. Taking a steel plant as an example, the operating environment is extremely complex. During the casting process, the crystallizer vibrates, and numerous and shared wiring lines further increase the error in the acquired liquid level signal pulse value. Moreover, the relationship between the liquid level value and the liquid level signal pulse value is not a simple linear one; liquid level signal pulse values ​​obtained through calibration using limited calibration points will also contain some error.

[0004] Furthermore, existing detectors lack encryption mechanisms between the detector and the receiving module. As industrial field projects increasingly demand data security and transmission stability, especially in application scenarios with high data security requirements, traditional detector devices can no longer meet actual needs.

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention.

[0023] In a preferred embodiment of this utility model, based on the above-mentioned problems existing in the prior art, an encrypted detector device is provided. This device is a radiation detection device, mainly used to measure the level of molten steel. It consists of a crystal 1, a photomultiplier tube 2, a high-voltage board (corresponding to the high-voltage generation circuit, etc.), a main board (including a microcontroller and other circuits), etc.

[0024] like Figure 1 As shown, the encrypted detector device includes:

[0025] Crystal 1 is a special material that can convert high-energy rays or particles into visible light or ultraviolet light. In practical applications, when high-energy rays or particles are incident on scintillation crystal 1, they interact with the atoms or molecules in crystal 1, resulting in energy transfer and the excitation of photons.

[0026] Photomultiplier tube 2 is connected to crystal 1. Photomultiplier tube 2 is used to convert the weak light signal generated by crystal 1 into an electrical signal under high voltage. A photomultiplier tube (PMT) is a highly sensitive photoelectric conversion device capable of converting light signals into electrical signals and possessing high gain. A photomultiplier tube typically consists of a photocathode, one or more dynodes, and an anode. When the photocathode is irradiated with light, it releases electrons. These electrons are accelerated by the multiplying electric field and collide with the next electrode, releasing even more electrons. This process is repeated between the dynodes, ultimately generating a large current signal at the anode.

[0027] High voltage generating circuit 3 is connected to photomultiplier tube 2; high voltage generating circuit 3 is used to provide high voltage to photomultiplier tube 2, so that weak light signals are converted into electrical signals.

[0029] The pulse waveform shaping circuit 5 is connected to the voltage discharge circuit 4. The pulse waveform shaping circuit 5 is used to shape the electrical signal obtained by the photomultiplier tube 2 after it has been converted by the comparator. After shaping, the electrical signal has a more regular waveform, which is convenient for subsequent accurate acquisition and processing by the microcontroller.

[0030] Microcontroller 6 is connected to both pulse waveform shaping circuit 5 and encryption chip circuit 8. Microcontroller 6 is the core control component of the device, and its timer external interrupt pin acquires the electrical signal output from pulse waveform shaping circuit 5. The acquired data is then encrypted by encryption chip circuit 8.

[0031] The receiving module 11 is connected to the microcontroller 6 via a carrier circuit 10 composed of digital signals and power. The microcontroller 6 transmits the encrypted signal to the receiving module 11 via the POWERBUS bus using carrier communication. The receiving module 11 then further processes and displays the data.

[0032] The encrypted detector device in this embodiment transmits data digitally, which significantly enhances its anti-interference capabilities and improves data stability compared to traditional devices that transmit data in analog form. Furthermore, because the device incorporates an encryption mechanism, the likelihood of it being replaced by competitor products in the field is greatly reduced, preventing customer loss and thus generating substantial economic benefits.

[0033] In a preferred embodiment, the system further includes a temperature acquisition circuit 7, which is connected to a microcontroller 6. The temperature acquisition circuit 7 is used to measure the temperature of the molten steel in real time.

[0037] In a preferred embodiment, the encryption chip circuit 8 is connected to the microcontroller 6 via an I / O port. The encryption chip circuit 8 is used to encrypt the data collected by the microcontroller 6, thereby enhancing the security of data transmission.

[0038] In a preferred embodiment, the system further includes a first LDO power supply circuit 13, which is connected to the high voltage generating circuit 3 and is used to generate a second voltage based on the first voltage.

[0039] In this embodiment, the first voltage is preferably 12V.

[0040] In this embodiment, the second voltage is preferably 5V.

[0041] Specifically, the first LDO power supply circuit 13 is used to convert the first voltage 12V into the second voltage 5V, providing a stable operating voltage for the high voltage generating circuit 3.

[0042] In a preferred embodiment, the system further includes a second LDO power supply circuit 14, which is connected to the microcontroller 6 and is used to generate a third voltage based on the first voltage.

[0043] In this embodiment, the third voltage is preferably 3.3V.

[0044] Specifically, the second LDO power supply circuit 14 is used to convert the first voltage 12V into the third voltage 3.3V to provide a stable operating voltage for the microcontroller 6.

[0045] In a preferred embodiment, the system further includes a bus power processing circuit 12, which is connected to the first LDO power circuit 13 and the second LDO power circuit 14 respectively, for providing a first voltage.

[0046] In a preferred embodiment, the bus power processing circuit 12 is electrically connected to the receiving module 11.

[0047] In this embodiment, the bus power processing circuit 12 is connected to the receiving module 11 via the POWERBUS bus and is used to convert the POWERBUS bus voltage into a first voltage of 12V.

[0048] The encrypted detector device proposed in this invention is used as a radiation detection device to measure the level of molten steel. Its working principle is as follows:

[0049] When high-energy rays or particles enter crystal 1, crystal 1 converts them into visible light or ultraviolet light, generating photons. Under the high voltage provided by the high-voltage generation circuit 3, photomultiplier tube 2 converts the weak light signal generated by crystal 1 into an electrical signal.

[0050] After the pulse signal emitted by the photomultiplier tube 2 is output through the high voltage generation circuit 3, the pulse voltage is successively amplified by the operational amplifier through the voltage discharge circuit 4 and shaped by the pulse waveform shaping circuit 5.

[0051] The microcontroller 6 acquires the shaped electrical signal through the external interrupt pin of the timer. The acquired data is transmitted to the encryption chip circuit 8 for encryption processing. The encrypted data is transmitted to the receiving module 11 in digital form through the carrier circuit 10.

[0052] The device solves the problems of signal interference and attenuation in long-distance transmission and encrypted communication through the coordinated operation of the aforementioned components. It enhances anti-interference capabilities and data stability, reduces the possibility of being replaced by competitors' products, and creates economic benefits for the company.
