    摘要: An elevator level warning system is provided, along with methods of use thereof. An elevator level warning system may include a controller, a laser, a sensor, and a reflector. The reflector may be a structured reflector. The elevator level warning system may also include a sensor board. The elevator level warning system may also include an indicator. The elevator level warning system may be used with an elevator system. The elevator level warning system may be used to detect that-and/or warn users that-a front cab-floor edge and a landing plane are misaligned and have a drop between them of greater than a threshold distance.

    摘要: A power supply circuit for powering components of a facility are disclosed. The power supply circuit may include a power transformer, a power input terminal, a power output terminal, a bridge, a relay, and a control circuit. The relay is connected between the power input terminal and the power output terminal. A primary side of the power transformer is coupled between the relay and the power output terminal. The bridge is coupled to the secondary side of the power transformer. In a normal power mode, the control circuit closes the relay and operates the bridge as a rectifier. In an emergency power mode, the control circuit opens the relay and operates the bridge as a pulse width modulator. In this manner, the bridge and the power transformer can be used both to charge a battery during normal operation and generate emergency AC power from the battery.

    摘要: An elevator pit safety system is provided, along with methods of use thereof. An elevator pit safety system may include a control system, an emergency stop switch, and a power switch. The emergency stop switch may be configured to stop an elevator cab. The power switch may be configured to operate a lighting system. The control system may prevent either from being used without the other. The elevator pit safety system may be configured to allow overriding the safety features.
