As shown in Figure 1, a kind of radio voice pinboard, for its device in intercom for elevator system, it includes 1 road interface, 1 Road intercommunication signal acquisition/receiving circuit, 2 road interfaces, 2 tunnel intercommunication signal acquisitions/receiving circuit, microcontroller, channel selecting, connection Elevator interior intercom system circuit, send alarm off-hook on-hook signal, voice switching hands-free phone circuit, telecommunication circuit, work( Put amplifying circuit, PAC circuit, outside line interior lines receive signal acquisition, voice isolation circuit, OUT interfaces, the 1 road interface string Join 1 tunnel intercommunication signal acquisition/receiving circuit and connects the microcontroller, 2 road interface tandem, 2 tunnel intercommunication signal acquisition/reception Circuit connects the microcontroller, and the microcontroller is also connected with the channel selecting, connection elevator interior intercom system circuit, sends Alarm off-hook on-hook signal, voice switching hands-free phone circuit, outside line interior lines receive signal acquisition, the outside line interior lines connect It receives signal acquisition and is also respectively connected with the transmission alarm Zhai Ji on-hook signals, voice isolation circuit, the voice isolation circuit Be also respectively connected with telecommunication circuit, PAC circuit, OUT interfaces, the voice switching hands-free phone circuit be separately connected telecommunication circuit, Power amplifier amplifying circuit, the power amplifier amplifying circuit connect the PAC circuit.

Radio voice pinboard connection and be operated in existing intercom system can with external communication system communication without The institute for influencing existing intercom system is functional.

In the present embodiment, the utility model circuit includes：Power supply stabilization circuit, intercom dtmf signal acquisition/reception Circuit, microcontroller and peripheral circuit, voice switching hands-free phone circuit, voice isolation circuit, voice amplification circuit, elevator interior The bridgt circuit of intercom gating circuit, DTU transmission dtmf signals receiving circuit, DTU control voice signal instructions.It can not only Enough realize elevator interior intercom, can also in real time to the off-hook of elevator interior talk back equipment, on-hook, the acquisition of call signal, Form the intercommunication of multifunctional remote monitoring elevator, when analyze elevator service condition equipment.

We use 78L05 voltage stabilizings to power supply stabilization circuit, and between input terminal and output end and upper rectifier diode, Afterflow instantaneous variation can damage 78L05 from preventing when there is backward voltage, and place is filtered by L3 filters after output voltage stabilizing After reason, the 5V voltages to reach requirement standard supply the use of the utility model modules circuit.

Intercom signal acquisition uses full-wave rectifying circuit, mainly defeated by forming for four rectifier diodes and peripheral circuit Enter AC signal full-wave rectifying circuit, when exporting as DC pulse signal to U2 optocouplers, can realize the acquisition of intercom signal.

In intercom signal two-way receiving module and when each function dtmf signal of DTU transmissions is received, we use Dtmf signal receiver U13/U14-HT9170 integrated chips complete the reception to elevator interior intercommunication dtmf signal.When When COM1/2 receives effective dtmf signal, DV pins are set to high level, and this dtmf signal is sent to inside Circuit is decoded.After OE pins are set to high level, D0 ~ D3 pins can just will produce decoding output and give data master control monolithic Machine processing.Similarly, dtmf signal receiver U8-HT9170 has been responsible for also the reception for each function dtmf signal that DTU is sent out, DTU, which is responsible for sending out, increases speech audio isolation circuit at dtmf signal front end, based on mainly voice frequency isolation transformer T3, keep away Exempted from due to caused by problem with grounding call exchange acoustic jamming, in order to DTU sends out dtmf signal can be smoothly by receiver U8- HT9170 is transferred to data main control singlechip, and traditionally increasing T2- audio-frequency transformers in reception dtmf signal front end can Reach dtmf signal smoothly to transmit, the damage for inputting equipment pole greatly reduces.

Data main control singlechip uses 8 STC microcontrollers and 8 51 series monolithics.The selection principle of microcontroller is System structure is simple as possible, dependable performance, 8 STC microcontrollers and 8 51 series monolithics etc..The selection principle of microcontroller It is simple to be to try to system structure, dependable performance is reliable and stable using STC microcontrollers for the angle of function, program download side Just quick, resource is saved, does not cause to waste；It is said from the angle of cost performance, with the obvious advantage, and the superior performance of STC microcontrollers. Main control singlechip STC15W410S internal resources meet system requirements, and cost-effective, and performance requirements reaches system and wants It asks, therefore, data main control chip uses STC15W410S microcontrollers.

For system when intercommunication dial-up occur and being connected to telephone relation intercommunication, this requires phone dial-up chip.Mesh Preceding phone is all made of dual tone multi-frequency signal generator, i.e. DTMF dial-ups technology.We use telephone dual tone multiple-frequency signal dial-up Chip U12-HT9200A, when DTU, which sends out dtmf signal, to be received by receiver U8-HT9170 after, U8-HT9170 will be received Dtmf signal is compiled into four two-stage system numbers and passes to data main control singlechip by decoding.Main control chip microcontroller is main U12-HT9200A program the beginning parts initialization Enable Pin and clock end are controlled, U12-HT9200A can be in intercom for elevator electricity Double-audio signal is sent in road, it is logical with extraneous personnel to realize to open corresponding elevator interior inning intercommunication according to gating circuit Talk about intercommunication, i.e. remote alarms.Similarly, the intercommunication of elevator interior car calling with and duty room host off-hook, on-hook signal quilt By data main control singlechip after reception, calling, off-hook, alarm signal are being sent from U16-HT9200A to DTU.It realizes The intercommunication of multifunctional remote monitoring elevator, when analyze elevator service condition equipment.

For system when there is communicating talkback, we use phone integrated speech switching hands-free phone chip U1-MC34118 And U2-MC34119 low-power audio amplification circuits, call conversion can be achieved by the bridge joint of peripheral circuit, send speech The processing of frequency, the design peripheral circuit of circuit can adjust it is called/send words sensitivity, called audio be sent into power amplifier pass/ Opening and closing, it is called to pass through voice frequency isolation transformer T3 and peripheral circuit, play the role of noise elimination sound call.
