Embodiment Construction

[0017] In order to meet the needs of one self-elevating tower crane in different locations and tasks, the self-elevating tower crane remote control system of the present invention includes 4 types of remote controllers (several types can be added according to work needs, and each type can be made into multiple remote controllers). ), the circuit structures of these four remote controls are exactly the same, but the operating frequency is different. The core component of the dual-tone command signal generation circuit in the remote control is the dual-tone telephone dial-up integrated circuit WE9178, and the keyboard input uses a single-contact 4*4 keyboard. Its key code has a one-to-one correspondence with the dual audio signal. One of the keys is set as a priority key. When you need to use the remote control to operate the self-elevating tower crane, you should first press the priority key, and then press other function keys, otherwise the operation of the self-elevating tow...

Abstract

A self-elevating tower crane remote control system is composed of a remote control transmitting system and a remote control receiving system, wherein the remote control transmitting system comprises four remote controllers, and each remote controller is composed of a keyboard circuit, a double audio frequency command signal generating circuit, a double audio frequency command signal transmitting circuit and a +9 V power source; the remote control receiving system is composed of three paths of remote control signal receiving circuits, a signal transmission switch circuit, a double audio frequency command signal decoding circuit, a command transmission switch circuit, a relay control circuit, a command decoder, fifteen solid-state relays, a voltage stabilizing power circuit or a door. The remote control system can be applied to various self-elevating tower cranes, remote control operation is easy, and cost is low.

Description

technical field [0001] The invention belongs to the field of wireless remote control, in particular to a remote control system for a self-elevating tower crane. Background technique [0002] Many self-elevating tower cranes work in harsh environments and cannot be remotely controlled, which will have a negative impact on the safety and health of workers operating self-elevating tower cranes on site. Contents of the invention [0003] The present invention provides a self-elevating tower crane remote control system aiming at the defects of the above-mentioned prior art, and the self-elevating tower crane can be remotely operated by using the remote control system. [0004] The technical solution adopted by the present invention to solve the technical problem is: a self-elevating tower crane remote control system, which is composed of two parts: a remote control transmitting system and a remote control receiving system. Each remote control in the transmitting system is comp...
