Embodiment 1

[0024] Such as figure 1 A multifunctional portable surface and underwater radiation pollution detector is shown, including a probe and a host, wherein the probe includes a second controller, a detector and a signal processing circuit, and the signal processing circuit converts the pulse signal output by the detector into a voltage The signal is output to the second controller, and the second controller has the type information of the detector;

[0025] The host computer includes a first controller and a high-voltage module. The first controller obtains the data of the second controller and judges the detector type, and configures parameters such as alarm threshold and nuclide use according to the detector type. If the detector is non-semiconductor detection According to the type of the detector, the high-voltage module is controlled to provide the corresponding high-voltage power supply to the detector, and the first controller also analyzes the data of the second controller t...

Embodiment 2

[0028] This embodiment discloses a specific implementation manner on the basis of embodiment 1.

[0029] Such as figure 1 As shown, the host includes a first controller, a high voltage module, a display screen, buttons, a CAN bus communication interface, an RS232 communication interface, a buzzer, a second power processing circuit and a battery. Wherein, the second power processing circuit and the battery constitute the power supply of this scheme, which can be powered by batteries or external direct power supply; the display screen constitutes the display device of this scheme; the buttons constitute the parameter input device of this scheme, which Structures such as a touch screen can also be used; the RS232 communication interface constitutes the external interface of the scheme; the buzzer constitutes the alarm device of the scheme, which can also be realized by a light alarm device. The probe includes a second controller, a CAN bus communication interface, a power proces...

Embodiment 3

[0034] Such as figure 2 As shown, this embodiment is optimized on the basis of the above embodiments, that is, before the first controller obtains the category information of the detector, it also includes a self-inspection step, and the main components such as the high-voltage module, the alarm device, and the CAN bus communication interface The functional components are tested, and if there is a fault, the operation will be terminated; if there is no fault in each part of the host, the probe type information will be obtained and the parameter configuration information will be sent. The specific process is:

[0035] 1. Host power-on initialization and self-test;

[0036] 2. The first controller detects the performance of the main functional parts of the host, if the self-test is successful, go to step 4, otherwise, go to step 3;

[0037] 3. Fault detection, identification and processing, and end the operation;

[0038] 4. Turn on the CAN bus communication module and send ...

Abstract

The invention discloses a multi-functional portable surface and underwater radiation pollution detector. The multi-functional portable surface and underwater radiation pollution detector comprises a probe and a host machine connected with each other through a communication interface; the probe comprises a second controller, a detector and a signal processing circuit; the signal processing circuit converts pulse signals outputted by the detector into voltage signals and outputs the voltage signals to the second controller; type information of the detector is stored in the second controller; the host machine includes a first controller and a high voltage module; the first controller acquires the data of the second controller and judges the type of the detector; if the detector is a non-semiconductor detector, the first controller controls the high voltage module according to the type of the detector to make the high voltage module provide a corresponding high-voltage power source to the detector; and the first controller carries out analysis according to the data of the second controller to realize pollution detection. The probe and the host machine are connected with each other through the communication interface, so that a user can replace corresponding types of probes according to detection needs, and therefore, object surface and underwater radiation pollution can be monitored, and the problem of the monotonicity of the performance of a radiation monitoring instrument can be solved.

Description

technical field [0001] The invention relates to the technical field of radiation detection, in particular to a multifunctional portable surface and underwater radiation pollution detector. Background technique [0002] At present, most of the portable instruments and meters used in nuclear facilities to monitor surface and underwater radiation pollution are produced by foreign manufacturers, such as those used to detect residual α, β and underwater γ radioactive pollution in personnel clothes, tools, ground, etc. Professional setting. The probes of existing radiation pollution detection equipment are integrated in the host, and a detector can only use one type of probe to realize radiation monitoring, and its performance is single. When testing, different testing equipment needs to be replaced according to the monitoring situation, which is very inconvenient to use. [0003] Therefore, how to effectively solve the problem of single performance of portable surface and under...
