The present embodiment provides an elevator direction determination device after an unexpected power failure, as shown in fig. 1 to 4, including: the refuge system comprises a flat layer position magnetic isolation plate 1, a non-flat layer position magnetic isolation plate 21 above a refuge layer, a non-flat layer position magnetic isolation plate 31 below the refuge layer, a flat layer inductor 4 and a main controller; wherein, the flat bed position magnetism shield 1 sets up floor flat bed region in the well, and it includes: the flat layer position X signal magnetism isolating part 11, the flat layer position Z signal magnetism isolating part 12 and the flat layer position Y signal magnetism isolating part 13 are arranged on two different sides of the flat layer position Z signal magnetism isolating part 12; the non-flat position magnetic shield 21 above the refuge floor is arranged in the well, namely the non-flat position above the third floor in fig. 1, and comprises: the X signal magnetism isolating part 2111 at the non-flat layer position above the refuge layer and the Z signal magnetism isolating part 2212 at the non-flat layer position above the refuge layer are connected with each other; the magnetic isolation plate 31 at the non-flat position below the refuge floor is arranged in the hoistway, namely at the non-flat position below the third floor in fig. 1, and comprises: a Z signal magnetism isolating part 3112 at a non-flat layer position below an evacuation layer and a Y signal magnetism isolating part 3213 at a non-flat layer position below the evacuation layer, which are connected with each other; the transmitter of the leveling sensor 4 is arranged, and the receiver of the leveling sensor 4 is arranged; the main controller is connected with the leveling sensor 4, and the current position of the lift car is judged according to the sensing signal of the leveling sensor 4.
The X signal transmitting part, the X signal receiving part, the flat layer position X signal magnetism isolating part 11 and the non-flat layer position X signal magnetism isolating part 2111 above the refuge layer are positioned on the same straight line; the Z signal transmitting part, the Z signal receiving part, the flat layer position Z signal magnetism isolating part 12, the Z signal magnetism isolating part 2212 at the non-flat layer position above the refuge layer and the Z signal magnetism isolating part 3112 at the non-flat layer position below the refuge layer are positioned on the same straight line; the Y signal transmitting part, the Y signal receiving part, the flat layer position Y signal magnetism isolating part 13 and the below-refuge layer non-flat layer position Y signal magnetism isolating part 3213 are positioned on the same straight line. When the emitter of the flat sensor 4 sends signals to the receiver of the flat sensor 4, the shapes of the flat position magnetic isolation plate 1, the non-flat position magnetic isolation plate 21 above the refuge layer and the non-flat position magnetic isolation plate 31 below the refuge layer are all the same, so that the receiver of the flat sensor 4 receives different signals and sends the signals to the master controller, and the master controller judges the running direction of the lift car according to the different signals.
Specifically, when the car is located at the leveling position, the X signal, the Z signal and the Y signal are blocked due to the shape of the leveling position magnetism isolation plate 1, the leveling sensor 4 receiver cannot receive the signals, otherwise, when the leveling sensor 4 receiver does not receive the signals, the master controller judges that the car is located at the leveling position; similarly, when the elevator car is located at the non-flat position above the refuge floor, the receiver of the flat sensor 4 can only receive the Y signal, so when the receiver of the flat sensor 4 only receives the Y signal, the main controller judges that the elevator car is located at the non-flat position above the refuge floor, and at the moment, the self-rescue direction of the elevator is downward; when the elevator car is located at a non-flat floor below the refuge floor, the receiver of the flat floor sensor 4 can only receive the X signal, so when the receiver of the flat floor sensor 4 receives the X signal, the main controller judges that the elevator car is located at the non-flat floor position below the refuge floor, and the self-rescue direction of the elevator is upward.
Preferably, the flat bed inductor 4 is an infrared inductor.
Preferably, the magnetic shield plate 1 at the flat layer position, the magnetic shield plate 2 at the non-flat layer position above the refuge layer, and the magnetic shield plate 3 at the non-flat layer position below the refuge layer are metal magnetic shields.
