Abstract
The utility model relates to a double-sound multi-frequency controlled elevator intercom bus system device, belonging to the intercom network field of maintaining an elevator with fault. The utility model is characterized in that two ends E and G of the local intercom device are connected to the power supply; the two ends L1 and L2 of the local intercom device are connected to a telephone subscriber line; the networking bus of the voice line T1, control line C1 and ground line G1 of the local intercom device is connected to the three ends of the voice line T1, control line C1 and ground line G1 of one to two thousand master machine room intercom devices; the two ends E and G of a master machine room intercom device are connected to the power supply; the voice line T2, control line C2 and ground line G2 of the master machine room intercom device are connected to an elevator bus composed of voice line, control line and ground line; three groups of the submachine intercom devices are connected to the elevator bus. Compared with the prior art, the installed capacity of the whole system can reach to 2000 sets; under the requirements of the electromagnetic compatibility, the maximum communication distance can be reached to 10 kilometers; when the bus is busy, the calling signal can be sent out in real time by any other extension set.
Description
[technical field]
Speech path network field when the utility model relates to elevator faults warning and maintenance, specifically a kind of elevator conversation bus system device of dual-tone multifrequency control.
[background technology]
Present elevator phone system, adopt multiple-way system mostly, communicator (hereinafter to be referred as extension set) in each lift car adopts Y-connection with machine room communicator (hereinafter to be referred as machine tool), wiring is complicated, cost is higher, and institute's extension quantity is difficult for increasing in the net, is difficult to satisfy the estate management requirement of large-scale sub-district.
When the conllinear type voice communication telephone set (being stated from 1997 the 5th phases of radio) that the permanent special Research on Communication Technology in mill, state-run beach is produced is conversed owing to the interior a pair of telephone set of net, other telephone sets can not send call signal, and this does not meet the real-time requirement of elevator warning phone system.
Bus-type telephone system (patent of invention publication number CN1115933A) has above-mentioned shortcoming equally, and controls decoder with address pulse, and in the transmitting time of signal, the performance of transmission range and antijamming capability aspect is not the best.
[summary of the invention]
The purpose of this utility model is in order to overcome above-mentioned shortcoming, to provide an installed capacity can reach 2000 speech path network device at most, and under the situation of bus busy (conversation), other arbitrary communicators can both send call signal in real time.
For achieving the above object, design a kind of elevator conversation bus system device of dual-tone multifrequency control, comprise the telephone set communicator, it is characterized in that local call device EG two ends connect power supply, local call device L1 is connected telephone loop with the L2 two ends, local call device voice lines T1, control line C1, the networking bus of ground wire G1 connects the voice lines T1 of one to 2,000 machine tool machine room communicator, control line C1, ground wire G1 three ends, machine room communicator EG two ends are connected to power supply, voice lines T2 on the machine room communicator, control line C2, ground wire G2 connects by the language line, control line, the elevator bus that ground wire is formed is connected to three groups of handset communicators on elevator bus; Three copper conductors of voice lines, control line, ground wire that networking bus and elevator bus adopt sectional area to be not less than 0.75 square millimeter constitute; Carry out the transmission of control information on the control line with the touch-tone signal line; Purple assignment key and maintenance and debugging key also are housed on the car communicator; Every group of handset communicator connects voice lines T2, control line C2, ground wire G2 on sedan-chair top pit communicator, car communicator, the sedan-chair top communicator respectively by elevator bus; Rational correct coding is adopted in being connected of machine tool and handset, and as the high address sign indicating number, as address code, machine tool last digit 0 is represented the individual bit address sign indicating number of machine tool to handset to machine tool with a position 1-9 with kilobit, hundred, ten.
The utility model is compared with prior art, makes the most nearly 2000 of whole system installed capacitys; Control is reliable, and under the requirement of satisfying Electro Magnetic Compatibility, maximum communication distance can reach 10 kilometers; Bus is under the situation of busy (conversation), and other any extension sets can both send call signal in real time, and small investment is effective, is worthy of promotion and application.
[description of drawings]
Fig. 1 is connection side's block diagram of the present utility model.
Fig. 2 is an electrical schematic diagram of the present utility model.
Appointment Fig. 1 is a Figure of abstract.
Referring to Fig. 1,1 is local call equipment; 2 are the networking bus; 3 is machine tool machine room communicator, can be made of 1 machine tool to 2000 machine tool; 4 is elevator bus, is connected to 5,6,7 three groups of handsets on elevator bus, and three phones are housed on every group of handset.Fig. 2 has provided electrical schematic diagram of the present utility model, and the manufacturing technology of sort circuit is clearly to this professional people.
[embodiment]
Below in conjunction with accompanying drawing the utility model is described in further detail.
The local call device adopts the LT-Z1 telephone set, connect machine tool machine room communicator by the networking bus, machine tool machine room communicator adopts the LT-M2 model, connect elevator bus on the machine tool communicator, elevator networking bus is identical with the networking bus structures, all being not less than 0.75 square millimeter copper conductor by three sectional areas constitutes, be defined as the T-voice lines, the C-control line, the G-ground wire, regular phone system touch-tone signal and voice signal transmit on same lead, touch-tone signal is separated from voice lines, increase a C-control line, purpose is to make bus still can send call signal under the situation of busy (conversation), every machine tool has an elevator bus that belongs to it, can connect 9 extension sets at most, like this conversation of each machine tool and extension set parallel carrying out simultaneously.Machine tool links to each other with the local call device by the fast network bus in inside, what control line C1 went up transmission is the address that four decimal numbers are formed, what control line C2 went up transmission is the address that one digit number constitutes, kilobit, hundred, ten number have been determined machine tool and its subordinate's extension set high address, units 1-9 represents the address of 9 extension sets of machine tool subordinate, and 0 represents the individual bit address of machine tool.The dual-tone multifrequency mode transmits control signal on C, sending 1 decimal number stipulated time is 25 milliseconds.This technology is to implement easily to this professional people.
