[Shiyan, Hubei Jingmen Ezhou Huanggang, Xiaogan Xianning Suizhou] lease Lang opened electronics factory 15858153311 XCMG | most professional | solid | strong signal construction site lifts Professional pager | construction elevator leasing professional wireless pager factory floor construction elevator wireless pager (professional, sturdy , strong signal, the expert level) currently used in a large number of people and goods builder dual construction lifts (also known as the construction elevator), are not equipped with the hanging cage contact signaling device drivers. Therefore, on each floor of the cage needs to summon the floor open to the need to inconvenient, many sites often used percussion lift attached to the wall pipe approach to enable the driver to know someone required, it is neither safe nor accurate signal. In order to change the current situation, Lang opened the electronics company has developed a construction elevator floor pager, it is a wireless calling devices, the use of wireless modulation control technology, through wireless transmission and digital display technology, formed a set of advanced pager floors , so as to solve construction lift encounter suffering. Program configuration: each floor equipped with a pager device that uses a wireless signal amplitude modulation coding techniques to wireless transmission through a dedicated bus way, the signal accurately distributed to drivers, so drivers know exactly what to use the elevator floor and driving to the floor to work. In the field of construction, construction elevator use is becoming increasingly popular. With higher floors, reasonably convenient to lift the construction schedule, improve operational efficiency, the company developed a special construction lifts wireless call system, referred to as floor pager. Construction workers and solve communication problems lifts operating workers, reducing the construction elevator safety problems, which greatly improves the efficiency in the use of lifts. The system uses advanced wireless communication, independent coding and decoding technology, use of SAW devices steady frequency, frequency stability, reliable operation, easy installation. One, the system features a host and radio buttons are used industrial design, waterproof, dustproof, anti-strike, ideal for construction sites complex environments. 2 LED is highlighted, you can simultaneously display multiple floors call information three loud music tips 4 uses 433MHz frequency wireless communication, without wiring, easy installation. 5 uses the latest encoding and decoding technology, each has a unique coded pager, pager interference will not occur between, there is absolutely no wrong. More than six transmitters transmit signals, or transmit more reliable. 7 clearings effective distance of 1000 m, lifts staff through the host display which floor you can see the call information to which floor to go to work. Second, the system structure of the system is installed in the floor of each floor and the pager receiver installed in the lift cage display composition. Floor mounted pager corresponding to each floor. A 9V block battery, no power restrictions, without wiring. Pager, and lift cage floor without cable connection, the communication using wireless. Providing a lift cage in a radio receiving apparatus, the receiving means receives the radio signal amplification processing on the display connected to the floor call, when a layer of floor call, the host to which the display will show the number of floors, which floor to the driver go to work.
