根据本发明，一种用于密封容器门的装置包括：主体，其形成为允许引导孔和锁定孔穿过上端; 安装成沿着主体中的导向孔垂直滑动的锁定构件，并且具有插入容器门的机械密封孔中的锁定杆，同时在一侧的端部朝向锁定孔的内部和外部消失 ; 固定单元，其安装在主体内部，以在锁定构件的锁定杆插入到锁定孔内时固定锁定构件，并且一侧的端部朝向主体的外侧突出以释放固定构件的固定状态 通过使用者的操作来锁定构件; 安装在主体中的无密封认证单元与由外部用户携带的短距离通信模块进行无线通信; 保持单元，其通过主体内部的电能与固定单元的一部分接触或分离，通过与非定影单元接触来固定定影单元，以使其不与定影单元接触，以使得固定单元不被释放 由开封认证单元执行，并且当进行开封认证时，允许通过与定影单元分离来解除定影单元的拆卸操作; 密封检测单元，用于根据锁定构件的垂直运动来检测锁定构件的锁定状态和打开状态; 以及远程通信模块，用于将由所述密封感测单元感测的所述锁定状态和所述打开状态无线通信到外部安全管理服务器。

Container door seal according to the present invention includes a main body that is formed to guide the locking hole and the through hole at the upper end and; Is installed so as to slide up and down along the guide hole in the main body, the locking member with the one end of the locking bar is inserted into the mechanical seal seals the hole in the container doors while retracting toward the outside of the locking hole is provided with; Fixed to be installed on the inside of the body release the fixed state of the locking member the locking bar is locked and fixed to the locking member when the hole is inserted into the inner side, the locking member end portion is projected outside of the body by a user's operation of the unit; Seal off the authentication unit that is installed on the main body to an external user mobile short-range communication module and the wireless communication; Inside the main body is installed such that a portion of the fixed unit and in contact with or spaced apart by the electrical energy, the sealed off when the seal off the authentication by the authentication unit is not carried out in contact with the fixing unit supporting the release of the fixing unit operations done so that when the fixed unit fixed and performs the authentication seal off the fixed unit and the holding unit are spaced apart allowing the release of the fixed unit and the work; Seal sensing unit for sensing a locking and an open state by a locking member in accordance with the vertical movement of the locking member; It characterized in that it includes a telecommunications module for wireless communication with the lock and open state sensed by the sensing unit sealed to the external security management server.
