[0027] To solve the problem that there is no matching and convenient signal processing and display device for the detector in the prior art, with reference to Figure 1The utility model embodiment provides a kind of structure schematic diagram of detection result display device, and detection result display device includes: device main body 10, installation on the upper surface of device main body display screen 30 and installation in the signal processing module of device main body inside;Signal processing module includes: detection result output interface and at least one detector interface 60, detector interface 60 exposes on the outer surface of device main body;Detector interface 60 is connected with detector, for receiving the signal to be handled that detector acquisition, so that signal processing module handles the signal to be handled, obtains detection result;Detection result output interface is connected with the display information input interface of display screen, for showing detection result.

[0028] Signal processing module can be processor with signal processing capability, for example, central processing unit (CPU), micro processor (MP) or digital signal processor (DSP) or any one or multiple of processor.

[0029] Take LB6500 detector as an example, LB6500 detector is a Geiger-Miller dose rate probe, can be used to detect ionizing radiation (alpha particle, beta particle, gamma ray and X ray) intensity's counting instrument.By inflation pipe or chamber as probe, when the voltage applied to probe reaches certain range, ray in pipe every ionization produces a pair of ions, can amplify and be connected to electronic device to record an electric pulse of same size, thus measure the number of rays in unit time.

[0030] Based on this, signal processing module is connected with detector through detector interface 60, receives the electric pulse recorded by LB6500 detector, and signal processing is carried out on the electric pulse, so that the ray intensity corresponding to electric pulse is valued.Meanwhile, the detection result after signal processing module is valued, through the detection result output interface of signal processing module, detection result is output to display screen, and numerical value such as ray dose after numerical value is displayed by display screen, to facilitate staff observation.

[0031] Optionally, detector interface 60 can be provided with two or even multiple, can be connected with multiple detectors simultaneously, and display screen displays detection result according to each detector interface, to avoid detection result display confusion.In another possible implementation, two detectors are connected simultaneously for calibration, and according to the menu displayed by display screen and corresponding menu key, double-channel switching display can be carried out, to improve work efficiency.

[0032] Reference Figure 1The signal processing module, the detector interface and other components are all installed on the device main body 10, and the device main body 10 is similar to a test box, and the shape, size and the like depend on the selected signal processing module, display screen, detector interface and other components, and compared with the control cabinet of the nuclear power plant in the prior art, the hardware size of the signal processing module for processing the electric signal and the display screen for displaying the numerical value is smaller than that of the control cabinet, and according to the convenient design requirement, the components with smaller size can be selected to construct the detection result display device.

[0033] Optionally, the size of the device main body 10 can also be limited, for example, the size of the device main body 10 is 318*280*204mm, and the components meeting the functional requirements are selected in the size, in addition, in view of the convenience, safety and the like of the detection result display device, a handle, a safety lock and the like can also be arranged on the device main body 10, and foam filling can be arranged in the device main body to improve the anti-vibration effect of the device.

[0034] Therefore, the detection result display device provided by the application integrates the signal processing module and the display screen, the detector interface in the signal processing module is connected with the detector, so that the signal processing module and the detector can move together, and the received radiation signal collected by the detector is processed to obtain the detection result, which is displayed by the display screen. Compared with the control cabinet for realizing signal processing in the prior art, the detection result display device provided by the application can make the detector perform instant detection on the object to be detected without moving the metal barrel or other objects to be detected, and display the detection result, which is more convenient and has higher detection efficiency.

[0035] Next, with reference to the following embodiments, other possible implementations of the detection result display device provided above are described.

[0036] In one possible implementation, with reference to Figure 2 The application example diagram of the detection result display device provided by the embodiment of the application is as follows: the detector interface includes a cable interface and a signal transmission cable 110 with a preset length, the signal transmission cable 110 includes a detector access interface 90 and a detection signal output interface 100; the detector access interface 90 is connected with the detector, and is used to receive the to-be-processed signal collected by the detector 80; the detection signal output interface 100 is connected with the cable interface, and is used to input the to-be-processed signal to the signal processing module.

[0037] The connection between the detector and the detection result display device can be through a signal transmission cable. Considering that the object detected by the detector has a certain radioactivity, the signal transmission cable can be used to realize remote detection of the radioactive object. For example, a signal transmission cable with a length of 20 meters is used to remotely transmit the signal collected by the detector, which greatly reduces the radiation damage to the user caused by the detection object, i.e., the radioactive source.

[0038] The signal transmission cable also needs to have a detector access interface that can be connected to the detector. Considering that different models of detectors are adapted to different interfaces, a signal transmission cable with multiple detector access interfaces can be designed, or a socket converter or other components can be used to adapt to different models of detectors. Meanwhile, the signal transmission cable also needs to have a detection signal output interface that can be connected to the signal processing module, which is used to output the signal collected by the detector to the signal processing module for processing.

[0039] Optionally, the signal input interface of the signal processing module can be exposed on the outer surface of the device main body and connected to the detection signal output interface of the signal transmission cable. In this embodiment, the signal input interface can be connected to the cable interface, which can be a USB socket, an aviation plug, or the like.

[0040] In a possible implementation, the detection result display device further includes a signal processing module connected to an external power supply and a circuit protection module arranged between the connection line between the signal processing module and the external power supply.

[0041] Referring to Figure 1 In a possible implementation, the detection result display device further includes a power switch 20 arranged on the outer surface of the device main body 10. The power switch 20 is used to control the power-on and power-off of the detection result display device, and its main function is to turn on or off the current in the circuit. The power switch 20 responds to the operation of the user to realize the connection or disconnection of the internal circuit of the detection result display device, which can reduce the power consumption of the detection result display device on the one hand and ensure the normal operation of the circuit and the equipment on the other hand.

[0042] Referring to Figure 3This utility model provides an internal circuit connection diagram of a detection result display device, including: a push-button switch, a fuse, a running indicator light, an alarm indicator light, a fault indicator light, a processing unit, a reset button, a detector interface 1, and a detector interface 2. The processing unit includes a voltage conversion subunit, a processing and display subunit, a signal processing subunit, and an interface subunit. The processing unit can be considered as the signal processing module of the aforementioned detection result display device, while the voltage conversion subunit, processing and display subunit, signal processing subunit, and interface subunit are subunits used to implement the various functions of the signal processing module. Specifically, the voltage conversion subunit converts an AC220V voltage signal into a voltage signal suitable for each subunit in the processing unit; the interface subunit transmits the signal to be processed received by the detector interface 1 and collected by the detector to the signal processing subunit, which processes the signal to be processed to obtain the detection result. The signal processing subunit interacts with the processing and display subunit. After receiving the detection result, the processing and display subunit displays the detection result on the display screen for user viewing.

[0043] The push-button switch is a power switch. Pressing the power switch controls the connection of the internal circuitry of the detection result display device. In this example, the detection result display device is connected to an AC220V power supply, and the power is turned on by the push-button switch. The detector is connected to the detection result display device through detector interface 1 or detector interface 2. Figure 3 It can be seen that both detector interface 1 and detector interface 2 are connected to the interface module of the processing unit, which is used to transmit the signal to be processed collected by the detector to the signal processing subunit, and the signal processing subunit performs new signal processing on the signal to obtain the detection result.

[0044] The fuse serves as the circuit protection module for the detection result display device. This module automatically disconnects the short circuit when the internal circuit current exceeds a certain threshold, protecting the internal circuit from irreversible damage to components such as the signal processing module. Optionally, the circuit protection module can also be a thermistor, overcurrent protection resistor, or other similar components.

[0045] In one possible implementation, refer to Figure 1 The detection result display device also includes at least one indicator light 40, which is connected to the alarm signal output interface of the signal processing module.

[0046] Figure 1 In this system, the detection result display device can be equipped with multiple indicator lights. When multiple indicator lights are present, the display device needs to indicate the alarm type corresponding to each indicator light. Alternatively, the alarm type can be distinguished by the color of each indicator light. For example, Figure 1The first indicator light in the detection result display device corresponds to the radiation signal alarm, and the second indicator light corresponds to the alarm indicator light in the detection result display device Figure 3 The alarm indicator light in the detection result display device is triggered to emit light when the ray content value of the detection result obtained by the signal processing module is greater than the threshold value, so as to prompt the detection personnel that the ray content of the current detected radiation source exceeds the standard. For example, Figure 1 The second indicator light in the detection result display device corresponds to the fault indicator light in the detection result display device Figure 3 The fault indicator light in the detection result display device is used to prompt the running state of the signal processing module. If the signal processing module has a running fault or a signal processing function fault, etc., the signal processing module triggers the fault indicator light, the fault indicator light emits red light, indicating that the device cannot be used, and reminding timely troubleshooting and maintenance. Figure 1 The third indicator light in the detection result display device can correspond to the running indicator light in the detection result display device Figure 3 Referring to Figure 3 When the internal circuit is in the on state, the running indicator light can normally emit light, and if the internal circuit is in the off state due to the protection circuit module or the power switch, no current passes through the running indicator light, the running indicator light is extinguished, and the detection personnel is indicated that the current detection result display device is in the off state.

[0047] It can be understood that the indicator light plays a role of device state display or detection value alarm in the embodiment, and the above three indicator lights are only exemplary descriptions and are not the only implementation manner.

[0048] In a possible implementation, referring to Figure 1 The detection result display device further includes a character input module 70, and an alarm threshold output end of the character input module 70 is connected with an alarm threshold input end of the signal processing module.

[0049] It can be understood that the alarm threshold of the corresponding ray content is different for different detection objects, and therefore, the detection result display device of the embodiment of the application is designed with a character input module, which can be a numeric keypad or an alphabetical keypad, or a program input interface of the signal processing module, for inputting the alarm threshold to the signal processing module in response to the operation of the user. Based on this, the signal processing module can control the alarm indicator light according to the newly set alarm threshold, and improve the flexibility of detection.

[0050] In a possible implementation, referring to Figure 1 The detection result display device further includes a reset button 50, and the reset button 50 is connected with the indicator light 40.

[0051] Referring to Figure 3The reset button is a reset key, which is used to reset the alarm indicator lamp after triggering the threshold alarm of the detection value, so that the alarm indicator lamp is turned off. It can be understood that in order to achieve the reminding effect, the indicator lamp will remain on after the alarm indicator lamp is turned on. Even if the detection value has returned to the normal value, the lamp will continue to be on until the detection personnel manually press the reset button, and then the lamp is turned off. In this way, it is ensured that the detection personnel can clearly receive the alarm information.

[0052] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing embodiments of the present application are described in detail, for those skilled in the art, it still can be modified, or part of the technical features of the equivalent replacement, within the spirit and principles of the present application, any modification, equivalent replacement, improvement, etc., should be included within the scope of the present application.
