Technical Field

The invention relates to the technical field of ray detection, in particular to a ray on-site detection safety alarm system.

Background

The radiation detection has large radiation, and can cause great harm to the body. The harm of ionizing radiation to the human body mainly occurs by the radiation acting on the body in excess of the allowable dose. Radiation hazards include in vitro hazards, which are the damage to the body caused by radiation penetrating the skin, and in vivo hazards, which are the damage caused by ingestion, inhalation, or direct contact with radioactive materials. Of course, as a radiation detector, the radiation hazard is mainly in vitro. The ionizing radiation has the harmful effect on human cell tissues, mainly blocks and damages the cell activity function and causes cell death. The degree of injury to the human body from ionizing radiation is related to the dose of radiation received. The nature of the rule according to which the radiation biological effect occurs is different, and is often classified into random effect and deterministic effect. The random effect means that the harm caused by the radiation may or may not occur under certain irradiation conditions, and the random effect comprises cancers, hereditary diseases and the like. Statistics show that the incidence rate is related to the irradiated dose, but the severity of the disease is not related to the dose, so that the disease is difficult to cure once the disease occurs. The deterministic effect means that a certain degree of damage, such as acute radiation sickness, skin radiation sickness and the like, can occur as long as the irradiation dose reaches a certain value. Generally, the larger the dose, the heavier the lesion. In addition to its serious, such hazards are remedied at the modern medical level. The deterministic effect has a certain threshold, for example. The single irradiation dose of the gonad reaches more than 3Gy, and permanent infertility can be caused; the single irradiation dose of 0.5-2.0Gy or the cumulative dose of more than 15Gy of the eye crystals can cause the crystal turbidity; the single irradiation dose of the red bone marrow up to 1.5Gy or the cumulative dose of more than 20Gy may cause hematopoietic impairment and the like. Death can occur in a short period of time when exposed to extremely high doses of radiation. (1 kg of the irradiated object is 1 Gy., i.e., 1Gy =1J/kg, when the energy of the ionizing radiation absorbed by the irradiated object is 1J) GBZ117-2015, requirements for radiation protection for industrial X-ray inspection are as follows:

when the ray detection is carried out, the subarea management is carried out on the workplace, and warning marks are arranged on corresponding boundaries. The range of the peripheral dose equivalent rate greater than 15 μ Sv/h in the workplace should generally be classified as a control zone. The control zone boundaries should be suspended with clearly visible "no entry" X-ray zone warning signs. The operator operates outside the control zone boundary, otherwise special precautions should be taken. In the working process of the field flaw detection operation, other work should not be carried out in the control area at the same time.

The range of the dose equivalent rate more than 2.5 MuSv/h outside the control area boundary and around the operation is divided into a supervision area, and a clearly visible warning board that 'irrelevant people are prohibited from entering the inside' is hung on the boundary, and special people are set for warning when necessary. When the field flaw detection work is implemented in a multi-floor factory or construction site, the field condition is complex, the number of operators is large, and although a specially-assigned person warns, the operators are not timely informed of the emergency situation, so that accidental injuries can be caused. In order to better prevent irrelevant personnel from entering the site, the operators can find out dangerous conditions in time and can take relevant measures immediately.

Disclosure of Invention

The invention aims to provide a ray on-site detection safety alarm system which is easy to attract the attention of other personnel.

In order to solve the technical problems, the invention provides a ray on-site detection safety alarm system, which comprises a detector and a controller, wherein the detector is connected with the input end of the controller, and the output end of the controller is connected with an alarm device; the controller is in wireless communication connection with the mobile communication terminal of the control personnel.

Drawings

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

Fig. 1 is a schematic structural diagram of a ray on-site detection safety alarm system of the invention.

Detailed Description

As shown in fig. 1, the safety alarm system for radiation field inspection of the present invention includes a detector, and further includes a controller, wherein the detector is connected to an input end of the controller, and an output end of the controller is connected to an alarm device; the controller is in wireless communication connection with the mobile communication terminal of the control personnel. In this embodiment, the detector is a laser range finder and/or a radiation dose detector; the alarm device is an audible and visual alarm, and the mobile communication terminal is a mobile phone of a worker.

Audible-visual alarm device collects personnel and goes into alarming function and ray dose alarming function by mistake, receives and dispatches signal through controlling means to utilize the signal transmission after wireless transmission function will handle to give the operation personnel:

1) the laser ranging method is characterized in that laser emitted by a range finder is reflected by an object to be measured and then received by the range finder, and the range finder records the round trip time of the laser. Half the product of the speed of light and the round trip time is the distance between the rangefinder and the object being measured. When the irrelevant personnel get into the ray operation region, the acousto-optic alarm lamp gives an alarm and sends out voice prompt: operating on rays, do not go into!

2) The radiation dose alarm function can detect the dose equivalent and the dose equivalent rate value caused by X and gamma radiation. The dose equivalents and dose equivalent rate values may be read directly by the device display. The measurement data, the working time and the like can be stored in the dosimeter, and the dosage data is provided for the mistaken intruder to receive the radiation irradiation. The personal dosage alarm can preset dosage and dosage rate alarm threshold values, and can give out sound and light alarms when the dosage exceeds the threshold value so as to increase the protection distance.

The device monitors moving personnel, is stationary, can issue voice prompts when finding entry into an alert range, and can record on-site radiation dose values.

3) The instant messaging function, when finding the personnel that break into by mistake, information such as relevant warning and ray dosage are sent to the site work personnel in step, and the site work personnel can take urgent measure according to the information, avoid the injury.

Although specific embodiments of the present invention have been described above, it will be appreciated by those skilled in the art that these are merely examples and that many variations or modifications may be made to the embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims.
