However, although the reverse rotation phenomenon of each parking space can be avoided during forward rotation, two alternating current contactors and two PLC output points are needed for each parking space, and cost and space of a distribution box are increased. In order to reduce the number of AC contactors and PLC output points required by the system, the application adopts the following modes:

The second thermal relay, namely FR01 in fig. 1, is used for monitoring whether the loop is overloaded and protecting the motor on the upper layer, and since lifting of the parking spaces on the upper layer can only be carried out singly and the condition that a plurality of parking spaces lift simultaneously does not exist, only one second thermal relay is needed to be arranged, and the wire outlet end of the second thermal relay is electrically connected with the wire inlet end of the motor on each upper layer.
The lifting and transverse moving garage is characterized in that: the bottom parking stall can only the sideslip, and upper parking stall can only go up and down, in order to guarantee that the lifting and horizontal movement can go on smoothly, before controlling, need guarantee that the parking stall of upper strata all is on the upper strata, and the parking stall of bottom all is at the bottom. Before a control instruction is sent out, whether homing signals of all upper parking spaces are received or not can be judged, and the control instruction can be sent out only when all the upper parking spaces are homing; if the homing signals of all the upper parking spaces are not received before the control instruction is sent, the homing signals of all the upper parking spaces are firstly caused to homing by controlling the attraction of the forward-converting current contactor, the reverse-converting current contactor and the control motor contactor, and then the instruction is sent.
In one embodiment, based on any one of the embodiments, before sending a control instruction, the PLC controller determines whether to receive homing signals of all upper parking spaces, and sends the control instruction when all upper parking spaces are homing;

Specifically, if the bottom parking space has 101-105 five parking spaces, the upper layer has 201-206 six parking spaces, and the 202 parking space on the upper layer needs to be taken out, whether signals are present at all upper limits of the 201-206 parking spaces is judged first when PLC control is performed (all upper parking spaces are judged to be on the upper side). If signals exist, the forward-reverse transfer contactor and the motor contactor for controlling the 102-105 parking spaces are in suction, the 102-105 parking spaces are controlled to move right, the 202 parking spaces are moved out of the space for descending, and after all the 102-105 parking spaces move right in place, the 202 parking spaces are controlled to descend through the internal logic of the PLC; if the upper limit has no signal, the parking space is proved to be not in place on the upper limit, in order to ensure the security of the transverse movement, the parking space which is not in the upper limit is required to be lifted to the upper layer position by PLC logic control, and then a layer of transverse movement is moved out of the vacant position.
In one embodiment, the forward ac contactor and the reverse ac contactor each include a main contact and an auxiliary contact, and when the main contact of the forward ac contactor or the reverse ac contactor is on, the corresponding auxiliary contact is off.
In order to ensure that the lifting and the horizontal movement of the system are not carried out simultaneously, an auxiliary contact of the forward AC contactor is connected in series with a main contact of the reverse AC contactor; the auxiliary contact of the reversing alternating-current contactor is connected with the main contact of the forward-alternating current contactor in series, when the main contact of the forward-alternating current contactor KM1 is connected, the auxiliary contact of the reversing alternating-current contactor is disconnected, and the reversing alternating-current contactor KM2 is connected with the auxiliary contact of the forward-alternating current contactor KM1 in series and is disconnected at the same time; similarly, when the main contact of the reverse alternating-current contactor KM2 is switched on, the auxiliary contact of the reverse alternating-current contactor KM2 is switched off, and the forward alternating-current contactor KM1 is simultaneously switched off due to the fact that the forward alternating-current contactor KM1 is connected in series with the auxiliary contact of the reverse alternating-current contactor KM 2; so that KM1 and KM2 are not connected at the same time, and further the lifting and transverse movement of the two are ensured to be carried out at different times.
