Abstract
The utility model relates to the elevator operation management control technological field, particularly to an elevator wireless intercommunication transmission system. According to the technical scheme, the elevator wireless intercommunication transmission system comprises a machine room wireless emission reception apparatus (1), a car roof wireless emission reception apparatus (2), a car wireless emission reception apparatus (3), a pit wireless emission reception apparatus (4), a wireless emission reception apparatus (5), and a monitoring center (6), wherein the machine room wireless emission reception apparatus, the car roof wireless emission reception apparatus, the car wireless emission reception apparatus, and the pit wireless emission reception apparatus are connected with the wireless emission reception apparatus via wireless network (7); and the wireless emission reception apparatus is arranged at the monitoring center. According to the technical scheme of the utility model, the elevator and the maintenance personnel are associated via the radio, thereby making the elevator maintenance personnel be informed at the earliest time when something is wrong with the elevator, reducing and avoiding the happening of unexpected accidents, enhancing the safety management of the elevator, and saving the cost for conventional wiring of the elevator and decreasing the later maintenance expenditure.
Description
Technical field
The utility model relates to a kind of elevator wireless intercommunication transmission system, belongs to elevator operation and management control technology field.
Background technology
Along with developing rapidly of economy, the quantity cumulative year after year of domestic elevator, the elevator safety problem of thereupon bringing also emerges in an endless stream.When elevator breaks down, unavoidable people from pass event that occurs, trapped personnel was saved in the very first time, the topic that has become people to be concerned about most, elevator five (three) the square intercommunications of background technology need to realize communication by the loaded down with trivial details communication line of arrangement between guardroom and every elevator, construction bothers, expense is high, and later maintenance cost is also very high.
The utility model content
The utility model purpose is to provide a kind of elevator wireless intercommunication transmission system, utilizes the transmission means of radio intercommunication to carry out communication, has saved loaded down with trivial details wiring, and is efficient, energy-conservation, solves the problems referred to above that background technology exists.
Technical solutions of the utility model are:
Elevator wireless intercommunication transmission system, comprise machine room wireless transmitting and receiving device, sedan-chair top wireless transmitting and receiving device, car wireless transmitting and receiving device, pit wireless transmitting and receiving device, wireless transmitting and receiving device and Surveillance center, machine room wireless transmitting and receiving device, sedan-chair top wireless transmitting and receiving device, car wireless transmitting and receiving device connect wireless transmitting and receiving device with the pit wireless transmitting and receiving device by wireless network, and wireless transmitting and receiving device is arranged on Surveillance center.
Machine room wireless launcher, sedan-chair top wireless launcher, car wireless launcher and pit wireless launcher are separately positioned on machine room, sedan-chair top, car and the pit of elevator.
Elevator five side's intercommunications are respectively machine room, sedan-chair top, car, pit and Surveillance center, carry out communication by wireless between this five side.
Elevator and Surveillance center respectively tool for mounting the equipment of wireless transmitting function and receiving function is arranged, carry out communication between both sides by the principle of wireless talkback, save traditional loaded down with trivial details wiring, for the fail safe of elevator has increased guarantee, also saved a large amount of maintenance costs simultaneously.
Described machine room wireless transmitting and receiving device, sedan-chair top wireless transmitting and receiving device, car wireless transmitting and receiving device, pit wireless transmitting and receiving device, wireless transmitting and receiving device are and possess simultaneously wireless transmitting function and wireless receiving function.
Wireless transmitting function produces the radio-frequency carrier signal of emission by phase-locked loop and voltage controlled oscillator respectively, through Hyblid Buffer Amplifier, excitation is amplified, power amplifier, produces specified radio-frequency power, through the antenna low pass filter, suppress harmonic components, then go out by antenna transmission.
The wireless receiving function is the double superheterodyne mode, carry out the radio frequency amplification from the signal of antenna input after receiving and dispatching change-over circuit and band pass filter, at the process band pass filter, enter a mixing, will from the amplifying signal of radio frequency with from the first local oscillation signal of phase-locked loop frequency synthesizer circuit in first frequency mixer place's mixing and generate the first intermediate-freuqncy signal.The first intermediate-freuqncy signal is further eliminated the noise signal of neighboring trace by crystal filter.Filtered the first intermediate-freuqncy signal enters the intermediate frequency process chip, with the second local oscillation signal again mixing generate the second intermediate-freuqncy signal, the second intermediate-freuqncy signal by a useless spurious signal of ceramic filter filtering after, be exaggerated and frequency discrimination, produce audio signal.Audio signal enters volume control circuit and power amplifier and amplifies by amplification, band pass filter, the circuit such as postemphasis, and drives loud speaker, obtains the required information of people.
Of the present utility model transmitting and receiving, except antenna and impedance matching circuit, other circuit are all mutually independently.
The beneficial effects of the utility model: elevator and repair and maintenance personnel are connected by radio, make elevator can the very first time notify the elevator maintain and protection personnel when breaking down, reduce and avoided the generation of accident for no reason, strengthen the safety management of elevator, also saved traditional wiring cost and later maintenance expense for elevator simultaneously.Compare with background technology, saved the wiring between elevator main and night shift room, reduced the wire rod cost, construction cost; The background technology wire rod is aging in addition, and the repair and maintenance cost is high; There is not the problem that wire rod is aging and interrupt in the utility model.
