The sun photocell 11 is formed on one side of the helmet 10 to receive sunlight in a natural state and convert it into electric energy so as to supply power smoothly to each configuration using ultra low power. It is possible to provide a cost saving effect, and when the sunlight can not be supplied sufficiently, it can be partially charged through the safety cap holder 20.

Meanwhile, the solar cell 11 is formed on one side or both sides of the safety helmet 10 to sufficiently absorb sunlight even in the movement of a worker. When the user wears the safety helmet 10, It is preferable to have a size in one range.

The battery unit 12 is built in the safety helmet 10 and can be used for at least 8 hours which is a working standard working time. The solar energy collected through the solar cell 11 is converted into electric energy and stored So that the helmet 10 can be supplied. However, when sufficient solar energy can not be supplied from the solar cell 11 according to the climate change of the site, the external energy supplied from KEPCO may be transmitted to the safety cap rest 20, which will be described later, So that it can be supplied and charged. In addition, it is preferable that the battery inserted into the battery unit 12 be mounted with a small and light Li-ion battery.

The sensor unit 13 is formed so as to prevent dangerous factors in a field environment such as dust, chemical substances or heavy equipment, and human body accident by recognizing the body condition of a worker in advance. It generally includes temperature sensors, humidity sensors, dust sensor chemical sensors, and alcohol sensors.

For example, the temperature sensor is a sensor that responds to a change in temperature, and allows a worker and a field temperature to be checked. When the body temperature of the worker is abnormally high, the temperature sensor detects the temperature of the worker, It is recommended to allow workers nearby to recognize the rest and to check the ambient temperature of the site and to calculate the optimized temperature data at the construction site so as to prevent the construction .

The dust sensor and the chemical sensor are sensors for detecting fine dust or chemical substances floating on the site.

The camera unit 15 is attached to the front surface of the safety helmet 10 so that the camera can store the data for a time period of 5 minutes or more for use as a reference data in the event of a disaster, It is preferable to use a CCD camera that converts an image into an electric signal using a charge coupled device (CCD) and stores it as digital data in a storage medium such as a flash memory.

The speaker and microphone unit 16 can communicate with the field manager via voice so that the worker does not have to carry a separate walkie-talkie so that the work can be carried out smoothly or a danger signal is detected from the sensor unit 13 A warning beep is generated through the speaker so that the employee can respond quickly to the danger.

The GPS unit 17 transmits coordinate values of the external position information to the integrated management server 30 via the main controller, thereby preventing the worker from knowing the position of the worker and abruptly leaving the workplace.

The GPS unit 17 is installed to receive a signal transmitted from the GPS satellite and provide position and time information of the worker. The distance between the GPS satellite and the GPS receiver is calculated based on the arrival time of the radio wave transmitted from the satellite. Since the clock installed on the satellite and the clock mounted on the receiver do not coincide with each other, an error occurs. Therefore, it is necessary to receive the radio wave from four or more GPS satellites so that accurate positioning can be obtained.

The data transmitting and receiving unit 18 is capable of transmitting data received from the sensor unit 13, the camera unit 15 and the GPS unit 17 to the integrated management server 20, The data can be transmitted and received to the integrated management server 30 in real time using the wireless communication module (zigbee) when the wireless terminal 10 is worn.
