Abstract

The present invention relates to a remote status monitoring system for unmanned automatic environmental radiation (activity) monitors. The purpose is to enable a central monitoring center to determine in real time whether each unmanned automatic environmental radiation monitor is operating normally, thereby allowing management personnel to be immediately dispatched for maintenance if an unmanned automatic environmental radiation monitor is found to be in an abnormal operating state. This enables reliable, constant monitoring of environmental radiation in the relevant area and significantly reduces maintenance costs by minimizing management resources. The configuration comprises: a high-pressure ion ionization box that measures the amount of ion generated by ionization in the air to determine the intensity of the radiation (activity) and transmits the measured value; a wireless communication module connected to the high-pressure ion ionization box and transmitting the radiation (activity) measured value emitted from the high-pressure ion ionization box to a server of the central monitoring center via a communication network; a display panel connected to the high-pressure ion ionization box and displaying the radiation (activity) measured value received from the high-pressure ion ionization box; and a cooling fan that exhausts heated air.

It is composed of an auxiliary power unit connected to the above-mentioned control unit and wireless communication module, and which supplies emergency power to the control unit and wireless communication module when power is not supplied from the above-mentioned main power unit; the control unit is characterized by transmitting a power outage status signal to the central monitoring center through the above-mentioned wireless communication module when power is not supplied from the above-mentioned main power unit.

Description

A remote status monitoring system for unmanned environmental radiation monitoring The present invention relates to a remote status monitoring system for an unmanned automatic environmental radiation monitor, and more specifically, to a remote status monitoring system for an unmanned automatic environmental radiation monitor that is installed in an area surrounding a nuclear power facility, such as a nuclear power plant, measures environmental radiation, and transmits the measured values to a server of a central monitoring center via a communication network, thereby enabling the unmanned automatic environmental radiation monitoring system to be maintained at the highest level at all times by remotely monitoring the status of the unmanned automatic environmental radiation monitor, so that when an abnormality occurs, it can be immediately recognized and follow-up measures can be executed quickly. Generally, unmanned automatic environmental radiation monitors are installed in areas surrounding nuclear facilities, such as nuclear power plants, to continuously monitor environmental radiation. These monitors constantly measure ambient environmental radiation and transmit the data to a central monitoring server, and the monitoring center analyzes the environmental radiation information received by the central monitoring server to remotely monitor the environmental radiation situation in the areas surrounding the nuclear facilities. Korean published patent No. 10-2000-0063231 (published on November 6, 2000) discloses such a conventional unmanned automatic environmental radiation monitor and an environmental radiation monitor system. Looking briefly at the configuration of the unmanned automatic environmental radiation monitor among them, it relates to a remote-controlled environmental radiation monitor and is configured to include a radiation sensor unit for detecting radiation, a weather sensor unit for measuring weather conditions, an analog signal processing circuit unit, a digital signal processing circuit unit, a DC power supply unit for applying high voltage and driving ICs, a communication unit for remote transmission and reception of operation programs and measurement data, a microprocessor with a built-in firmware program for controlling and driving the communication unit and a GUI (Graphic User Interface) program for user convenience, and a high-voltage generator applied to the radiation sensor and a power supply unit that enables the environmental radiation monitor to continue operating even if a sudden power outage occurs. Conventional unmanned automatic environmental radiation monitors with this configuration measure ambient environmental radiation and transmit the measured values to a server at a central monitoring center; however, since the central monitoring center cannot verify the normal status of each individual unmanned automatic environmental radiation monitor at all, the monitors are maintained by having monitoring personnel periodically dispatch to each monitor to inspect its condition and repair it if an abnormality is found. Such conventional maintenance methods for unmanned automatic environmental radiation monitors have a major problem in that they cannot determine in real time whether each unmanned automatic environmental radiation monitor is in a normal state, so if an unmanned automatic environmental radiation monitor is not operating properly, environmental radiation monitoring of the surrounding area is not carried out for a long time until a regular inspection by management personnel, and in addition, maintenance costs are very high due to the large number of personnel and vehicles required for the regular inspection.
