[0028] The following will be described in detail in combination with the accompanying Figures 1-7 The present application is further described in detail.

[0029] The present application relates to a radiation detection device, mainly used for detecting X-rays, gamma rays and beta rays, etc. It can be widely used in non-destructive testing, nuclear submarines, isotope applications, hospital cobalt treatment, and background radiation level monitoring of residents around power plants.

[0030] Referring to Figure 1 , the radiation detection device comprises a charging module, a power module, a radiation detection module, a display module, an external device module, an audible and visual alarm module, a main control module, and a temperature and humidity detection module.

[0031] The charging module is connected with the power module, and is used for providing a voltage with a corresponding amplitude to the power module for charging. In some specific implementation manners, the power module comprises a battery. The battery can adopt a lithium battery.

[0032] The power module is connected with the radiation detection module, the display module, the external device module, the audible and visual alarm module, the main control module, and the temperature and humidity detection module respectively, and is used for providing a voltage with a corresponding amplitude for power supply.

[0033] The radiation detection module, the display module, the external device module, the sound and light alarm module, and the temperature and humidity detection module are connected with the main control module. Specifically, the detection signal of the radiation detection module can be transmitted to the main control module, the detection signal of other sensors connected with the external device module can be transmitted to the main control module, and the detection signal of the temperature and humidity detection module can be transmitted to the main control module. The main control module can send all the detection signals to the display module for display, and can also compare the detection signals with the signal threshold value, and send a signal to the sound and light alarm module for sound and light alarm when the limit is exceeded.

[0034] Next, the structure of each module will be exemplarily shown in a specific implementation scheme.

[0035] As shown in Figure 2 The power module can further include a first voltage stabilizing circuit and a second voltage stabilizing circuit. The first voltage stabilizing circuit includes a first voltage stabilizing chip U4, and the second voltage stabilizing circuit includes a second voltage stabilizing chip U5. The first voltage stabilizing chip U4 can be a chip of model XR2981. It is a DC / DC boost converter chip, and the common packaging form is SOP-8 or ESOP-8, which makes the layout and wiring of the chip on the circuit board more flexible. The working frequency is as high as 600KHz, which helps to improve the power conversion efficiency and reduce the size of the power supply system. The working temperature range is usually between -40°C and 100°C, which makes it applicable to harsh working environments. These characteristics can all help to reduce the size of the radiation detection device and improve portability. The second voltage stabilizing chip U5 can be a chip of model AMS1117. It is a low dropout linear regulator (LDO), which integrates an extremely low linear conduction resistance inside the chip to ensure the stability of the output voltage under various load conditions. The built-in overheat shutdown and current limiting protection mechanism will automatically cut off the power supply when the temperature is too high or the load is too large, which may cause damage to the chip, effectively preventing overload phenomenon.

[0036] The third pin, the fourth pin and the fifth pin of the first voltage stabilizing chip U4 are connected to one end of the battery B1, one end of the sixth capacitor C6 and one end of the seventh capacitor C7, and the first pin and the second pin of the first voltage stabilizing chip U4 are connected to the first end of the fifteenth resistor R15, the first end of the eighth capacitor C8, the first end of the fifth capacitor EC2, the first end of the ninth capacitor C9 and the third pin of the second voltage stabilizing chip U5 through the second diode D2; the sixth pin of the first voltage stabilizing chip U4 is connected to the other end of the fifteenth resistor R15 and the first end of the sixteenth resistor R16; the ninth pin of the first voltage stabilizing chip U4 is connected to the other end of the sixteenth resistor R16, the other end of the eighth capacitor C8, the other end of the fifth capacitor EC2, the other end of the ninth capacitor C9, the first pin of the second voltage stabilizing chip U5 and the first end of the tenth capacitor C10; the second pin of the second voltage stabilizing chip U5 is connected to the other end of the tenth capacitor C10; and the other nodes are grounded. The specific connection relationship can be referred to the drawing. It should be noted that the present application only describes the circuit devices and connection modes that can realize the functions, and the specific device models and parameters are not limited, and the person skilled in the art can select appropriate parameters according to the actual functional requirements.

[0037] Correspondingly, the specific circuit structure of the charging module is as shown in Figure 3 The charging chip U2 can be a chip of model TP4056.

It can be correctly connected regardless of the direction of insertion, greatly improving the convenience of use. It supports a power output of up to 100W, which can quickly charge the device and save charging time. The functions of each pin are as follows. VBUS: positive power supply, used to provide charging or power supply functions. GND: negative power supply, used for grounding. CC1, CC2: communication channel, used to determine the type and direction of the connected device. When the device is inserted, CC1 or CC2 will connect with the corresponding pin of the device, and the difference in resistance value is used to determine the type of device and whether it supports fast charging and other functions. D+, D-: data transmission channel, used for USB 2.0 data transmission. SBU1, SBU2: auxiliary channel, used to support audio output and other functions. In some cases, it can also be used to support DisplayPort (DP) ALT mode and other video transmission functions.

Pin 1 (GND): ground, usually connected to common ground of the circuit. Pin 2 (TRIG): trigger point, this pin is a key to trigger NE555 to start a time period. The upper edge voltage of the trigger signal must be greater than 2 / 3VCC, and the lower edge must be lower than 1 / 3VCC. Pin 3 (OUT): output pin. When the time period starts, the output pin of NE555 will move to a high potential of 1.7V less than the power supply voltage; at the end of the period, the output will return to a low potential of about 0V. At the high potential, the maximum output current is about 200mA. Pin 4 (RESET): reset pin. When a low logic potential is sent to this pin, the timer will be reset and the output will return to a low potential. It is usually connected to the positive power supply or ignored. Pin 5 (CONT / CTRL): control pin. This pin allows the trigger and threshold voltage to be changed by an external voltage. When the timer is in a stable or oscillating operation mode, this input can be used to change or adjust the output frequency. Pin 6 (THRES / THR): threshold / reset lock pin. When the voltage of this pin moves from below 1 / 3VCC to above 2 / 3VCC, the reset lock will be started and the output will be in a low state. Pin 7 (DISCH): discharge pin. This pin has the same current output capability as the main output pin. When pin 3 is low, pin 7 is in a low resistance state (conducting to ground); when pin 3 is high, pin 7 is in a high resistance state. Pin 8 (VCC): positive power supply pin. This is the positive power supply voltage end of the 555 timer IC, and the supply voltage ranges from +4.5V (minimum) to +16V (maximum). NE555 has three common working modes: monostable, multivibrator and oscillator mode.

[0042] The second pin THI of the boost chip U6 is connected to one end of the eleventh capacitor C11, one end of the seventeenth resistor R17, and one end of the fifth diode D5, respectively.
