    • An electro-mechanical lock for cargo containers or similar enclosed spaces such as storage units. The locking mechanism includes a dual-ratcheting mechanism, which is normally in the locked position, and which firmly secures doors of a container or other enclosure. To unlock the device, the user obtains a temporary access code and unlocks the device, either by a wireless interface or by, for example, a key pad. The device incorporates a rolling access code algorithm that changes the access code based upon a pre-defined customer selected time period during which the code is valid. Once the validity period expires the user must obtain a new access code from a secure access code source to unlock the device. When access is desired, the user contacts a remote secure access code source, which provides the access code for the associated lock and time period.
    • 用于货物集装箱或类似封闭空间的机电锁,例如储存单元。 锁定机构包括双棘轮机构,其通常处于锁定位置,并且牢固地固定容器或其它外壳的门。 为了解锁设备,用户通过无线接口或例如键盘获取临时访问代码并解锁设备。 该设备包括滚动访问代码算法,其基于代码有效期间的预定义的客户选择的时间段来更改访问代码。 一旦有效期到期,用户必须从安全访问代码源获取新的访问代码,以解锁设备。 当需要访问时,用户联系远程安全访问代码源,其提供相关联的锁定和时间段的访问代码。
