In an en­closed space such as a par­ti­cle ac­cel­er­a­tor tun­nel, en­sur­ing worker safety dur­ing a dis­as­ter is an issue of crit­i­cal im­por­tance. It is nec­es­sary to have a sys­tem in which the man­ager can know from out­side the tun­nel whether there is any worker left be­hind and whether the worker is es­cap­ing in the right di­rec­tion. Be­cause a global po­si­tion­ing sys­tem (GPS) is not avail­able in the tun­nel, we are de­vel­op­ing a dis­as­ter pre­ven­tion sys­tem that uses Wi-Fi to trans­mit the po­si­tion­ing of work­ers and two-way com­mu­ni­ca­tion. The Wi-Fi ac­cess point (AP) in­stalled in the tun­nel should be ra­di­a­tion re­sis­tant. Ad­di­tion­ally, the equip­ment car­ried by the worker is con­ve­nient and easy to carry. We tested the ra­di­a­tion hard­ness of com­mer­cial AP de­vices and de­vel­oped a smart­phone ap­pli­ca­tion to per­form lo­ca­tion in­for­ma­tion trans­mis­sion and si­mul­ta­ne­ous char­ac­ter trans­mis­sion. In 2019, we in­stalled the sys­tem on the J-PARC Main Ring and started its op­er­a­tion. In this paper, the func­tions of the de­vel­oped sys­tem and its prospects are de­scribed.
