The invention provides a wireless hall-call system for a construction elevator. The system comprises a frequency converter, an intelligent elevator control module, a trunk board and a plurality of hall-call boards, wherein the trunk board comprises a state acquisition unit, a message establishing unit and a wireless receiving and sending unit. The intelligent elevator control module comprises a wireless receiving unit and an instruction establishing unit, wherein the state acquisition unit is used for acquiring trigger signals of each hall-call board, the message establishing unit is used for generating a call message and sending the call message to the intelligent elevator control module, and the instruction establishing unit of the intelligent elevator control module is used for generating an operation instruction and sending the operation instruction to the frequency converter for execution. The invention further provides a wireless hall-call method for the construction elevator, the trunk board is utilized to generate the call message according to the state of each hall-call board acquired by data lines, the call message is sent to the intelligent elevator control module in a wireless communication mode, wireless communication nodes are reduced, and stability of the construction elevator is improved.

Wireless hall-call system and method for construction elevator

The invention relates to an intelligent wireless voice calling system. The intelligent wireless voice calling system comprises a receiving host arranged in a hoisting cage of an elevator; an emitter connected with the receiving host through a wireless frequency-modulated signal is arranged on each floor of a building; the receiving host comprises a host housing; a host control circuit is arranged on a circuit board inside the host housing; a power supply is connected with the host control circuit through a voltage stabilizing circuit; the host control circuit is connected with a receiving antenna on the outer side of the host housing through a signal receiving circuit. By the adoption of the scheme, the structure design is reasonable; the receiving host is arranged in the hoisting cage of the elevator, and the emitter connected with the receiving host in a wireless frequency-modulated manner is arranged on each floor of the building, so that when a worker on certain floor needs to use the elevator, an emitter switch on the current floor is pushed down to inform the receiving host, and thus the intelligent wireless voice calling system is very simple to operate.

Disclosed is a calling system for a traction-type building construction hoist, the system comprising a calling device (1) and a prompt device (2). The calling device (1) is in signal connection with the prompt device (2), and the calling device (1) is used for an operator to input calling information and can send the calling information to the prompt device (2); the prompt device (2) is used for receiving the calling information transmitted by the calling device (1) and prompting a driver; and the independently arranged calling system is used for calling a cage (6) of the traction-type building construction hoist. Firstly, the calling device (1) and the prompt device (2) are in direct signal connection, circuit arrangement is quite simple, and maintenance and inspection are facilitated. Secondly, the calling device (1) does not directly control the cage (6) to move up and down, but sends information to the prompt device (2), and prompts the driver by means of the prompt device (2), thereby endowing the driver with a higher control right, and the complex environment of a construction site can be flexibly handled.

The invention discloses a floor beeper for construction. The floor beeper comprises a base. An outer machine shell is arranged on the top of the base. A 9V alkaline battery is arranged in the outer machine shell. A sound surface device is arranged on one side of the 9V alkaline battery. An F115 transmitting chip is arranged on one side of the sound surface device. A touch screen operation panel is arranged on the top of the outer machine shell. A beeping button is arranged on one side of the touch screen operation panel. An alarm button is arranged at the bottom of the beeping button. A front camera is arranged on the other side of the touch screen operation panel. A loudspeaker is arranged at the bottom of the front camera. The communication problem of construction workers and lift operators is solved, potential safety hazards of lift construction are reduced, the handling time of emergency situations is saved, loss cost is greatly reduced, and communication of constructors and lift operators is effectively achieved.

Floor beeper for construction

The utility model discloses a construction elevator calling device, and relates to a construction elevator, in particular to the construction elevator calling device which facilitates the calling of the construction elevator The construction elevator calling device provided by the utility model is arranged in a construction elevator and a floor, and is characterized by comprising a display and a plurality of callers, wherein the display is arranged in the construction elevator; a plurality of callers are respectively arranged in each floor; and the callers are connected with the display through wireless signals The construction elevator calling device provided by the utility model is scientific in design, simple in structure and convenient to use; and a 315MHz high-frequency wireless communication mode is adopted and wire arrangement is not required, so that the construction elevator calling device is convenient to install Simultaneously a latest coding and decoding technology is adopted; and each caller adopts a unique code, so that interference cannot be generated among the callers The construction elevator calling device can be used on the thirtieth or even fortieth floor; and a construction elevator operator can see the calling information of each floor conveniently through a display screen and go to the floor to work
