Fig. 1 is a schematic diagram of a connection structure of an embodiment of a remote control system for an elevator governor according to the present application. Although the present application provides the device structure shown in the following embodiments or figures, more or fewer modular units may be included in the device based on conventional or non-inventive labor. In a structure in which there is no logically necessary causal relationship, the module structure of these devices is not limited to the module structure shown in the embodiments of the present application or the drawings.
Specifically, as shown in fig. 1, an embodiment of an elevator speed limiter remote control system provided by the present application may include:
a brake signal point RTD which is arranged on an elevator speed limiter and controls the elevator to stop when the brake signal point RTD is powered on;
the release signal point RRD is arranged on an elevator speed limiter, when the release signal point RRD is powered on, the elevator is released by the speed limiter, and the elevator normally operates;
the remote control end is arranged outside an elevator shaft of the elevator, a remote brake switch SGT and a remote release switch SGR are arranged on the remote control end, the remote brake switch SGT is connected with a brake signal point RTD and a voltage signal point 301 in series, and the remote release switch SGR is connected with a release signal point RRD and the voltage signal point 301 in series.
Wherein the remote brake switch SGT remotely controls whether the brake signal point RTD is energized, thereby controlling whether the speed limiter controls the elevator to stop. The remote release switch SGR controls whether the release signal point RRD is powered up, thereby controlling whether the speed limiter releases the elevator.
In this example, the remote brake switch SGT, the brake signal point RTD, and the voltage signal point 301 are connected in series to form a brake control circuit, and the remote brake switch SGT is used to control the on-off of the brake control circuit.
In this example, when the remote brake switch SGT is closed, the brake control circuit path and the brake signal point RTD are energized. When the braking signal point RTD is powered on, the speed limiter brakes the elevator, so that the elevator is stopped.
In this example, the remote release switch SGR, the release signal point RRD, and the voltage signal point 301 are connected in series to form a release control circuit, where the remote release switch SGR is used to control the on-off of the release control circuit.
In this example, when the remote release switch SGR is closed, the release control circuit is on, and the release signal point RRD is powered. When the release signal point RRD is powered on, the speed limiter releases the elevator to enable the elevator to run.
