The detection to the construction elevator among the prior art detects its speed, angle more, prevents that the elevator from because speed is too fast or the angle is too big to cause danger, and it can real-time accurate detection elevator height not have which system yet, and this embodiment lies in providing an elevator height detection controlling means, can be fast, accurate detect the real-time height of elevator. The specific implementation mode is as follows:
as shown in fig. 1 and 2, an elevator height detection control device includes:
the laser radar 1 is arranged at the bottom of the elevator 5 and used for measuring the real-time distance between the elevator 5 and the ground;
the information transmission module 2 is used for transmitting the real-time distance data to the server 3;
the server 3 is used for processing the real-time distance data and sending an instruction to the execution device 4 according to a processing result;
a plurality of executing devices 4 for receiving the instructions of the service end 3 and controlling the elevator 5 to stop at the appointed floor;
the laser radar 1 is in information communication with the server 3 through the information transmission module 2, and the server 3 is in information communication with the execution device 4.
The laser radar 1 is arranged at the bottom of the elevator 5 and has a laser and a receiver (not shown in the figure), wherein the laser generates and emits a light pulse which strikes the ground and is reflected back and finally received by the receiver. The receiver accurately measures the travel time of the light pulse from emission to reflection. Because the light pulses travel at the speed of light, the receiver will always receive the previous reflected pulse before the next pulse is sent out, and will not be affected by the adjacent pulses. Given that the speed of light is known, the travel time can be converted into a measurement of the distance between the lidar and the ground, and thus the height at which the elevator 5 is located. The frequency of laser beam emission can range from a few pulses per second to tens of thousands of pulses per second. In the embodiment, the requirement on the frequency of laser beam emission is not high, and the frequency of laser beam emission is 1-3 pulses per second. In this embodiment, single-point lidar is preferred for lidar 1, and single-point lidar has advantages such as lower cost and smaller volume.
When the elevator 5 moves, the laser radar 1 arranged at the bottom of the elevator 5 is driven to move, the laser radar 1 measures the distance H between the elevator 5 and the ground in real time, and sends real-time distance data to the server 3 through the information transmission module 2. The server 3 is provided with a processor 8, the processor 8 is pre-stored with the position where the elevator 5 needs to stay, the processor 8 processes the real-time distance data, judges the position of the elevator 5, compares the position of the elevator 5 with the pre-stored position where the elevator 5 needs to stay, judges whether the elevator 5 runs or stops, and then sends an instruction to the execution device 4, and the execution device 4 receives the instruction of the server 3 and controls the elevator 5 to move or stop.
This embodiment adopts laser radar 1 to detect the elevator height, sends real-time distance data to server 3 through information transmission module 2 to detect the position that 5 stops of elevator by server 3, and judge 5 stops still operations of elevator, send instruction control elevator operation to final controlling element, can reach the detection purpose conveniently, ensured security and efficiency in the elevator use simultaneously.

The information transmission module 2 can adopt a data line for transmitting data to the server 3; a wireless transmission module can also be adopted, and is preferably used conveniently.
The wireless transmission module adopts a transfer module of a TTL to network port and a router or a 4G DTU, and when the wireless transmission module is the transfer module of the TTL to network port and the router, the wireless transmission module is connected to the transfer module of the TTL to network port through a TTL interface of a laser radar to realize network port transmission data; after the network interface adapter board acquires the protocol of the radar, a local connection is established in a router mode to transmit data, and at the moment, a network interface adapter module and the router need to operate in the same gateway; a client establishes a Socket connection server (appointing an IP address and a port number of an external network of a server), and finds a corresponding server through the IP address; the server receives a client request by calling an accept method of the Serversocket to obtain a Socket, and the transmission of the laser radar local data to the server data is completed.
When the wireless transmission module adopts a 4G DTU, the TTL \ RS485/232 interface of the laser radar is connected with the 4G DTU to realize network transparent transmission data; a client establishes a Socket connection server (appointing an IP address and a port number of an external network of a server), and finds a corresponding server through the IP address; the server receives a client request by calling an accept method of the Serversocket to obtain a Socket, and the transmission of the laser radar local data to the server data is completed.
The optical axis of the detection light of the laser radar 1 is vertical to the ground.
Each floor corresponds to an actuator 4.
The executing device 4 is a relay, and after receiving an instruction sent by the service end 3, the relay 4 controls the elevator 5 to stop or continue to run in a power-on and power-off mode.
And the server 3 processes the real-time distance data, calculates the number of floors where the elevator 5 is located, and sends an instruction to the execution device 4 corresponding to the floor according to the number of floors.
When the elevator 5 runs, every pass through a floor, the detection distance of the laser radar 1 can be transmitted to the service end 3 through the information transmission module, the service end 3 calculates the floor where the elevator 5 is located, each floor corresponds to the relay of the floor, when the elevator 5 needs to stop at a certain floor, the service end 3 calculates that the floor where the elevator 5 is located is the same as the number of the prestored floors needing to be stopped, an instruction is sent to the relay on the floor, the relay on the corresponding floor is triggered to be in a working state, the relay is connected with a power supply, and the elevator 5 is controlled to stop.
The real-time distance between the elevator 5 and the ground is equal to a floor number coefficient, and the coefficient is 2.5-4.
The coefficient is set according to the height of the floor, and the height of a single floor is generally 2.5-4 meters. The real-time distance between the elevator 5 and the ground is equal to the number of floors x the height of a single floor.
The server 3 is pre-stored with an early warning distance, the server 3 compares the real-time distance data with the pre-stored early warning distance, and when the real-time distance is smaller than the early warning distance, the server 3 sends an instruction to the execution device 4 to control the elevator 5 to stop running.

The service end 3 further comprises an output device 7 for outputting the information of the floor where the elevator is located to the operator, and the output device 7 comprises a display screen or a player.
When the output device 7 is a display screen, the display screen will show the stopping or passing floor position of the elevator 5. When the elevator goes up, the floor display signal is increased by 1, and when the elevator goes down, the floor display signal is decreased by 1, so that the change situation of the position of the elevator when the elevator 5 runs is reflected.
