Abstract
The utility model provides a public address system that talkbacks that lock is wireless, includes transmitter and receiver, the transmitter include treater I, the input of treater I connect microphone, key control module and battery module respectively, a modulator is connected to the output, the receiver include treater II, the input of treater II connect demodulator and constant voltage power supply respectively, the megaphone is connected to the output of treater II. Utilizing KT -68 type PCB subassembly cooperation modulator, demodulator to realize the current wireless use of public address equipment, when making the operator on duty exchange, need not running to sentry box on duty and use the microphone conversation, directly use portable transmitter just can control on -the -spot megaphone wantonly and propaganda directed to communicate and talkback, be favorable to the interactive communication of site work personnel, floodgate efficiency is put in the improvement.
Description
Technical field
The utility model relates to ship lock dispatching communication technical field, specifically a kind of ship lock wireless talkback public address system.
Background technology
Ship lock is most widely used a kind of navigation structure, in order to ensure boats and ships smoothly by navigation channel, is made up of lock chamber, lock head, gate, approach channel and relevant device.
Existing ship lock Dispatching Scheme, need sluice gate person on duty to leave Sentry Box when boats and ships turnover lock, to lock chamber floor manager, scheduling, now on-the-spot noise is comparatively large, and the communication between person on duty and crewman is very inconvenient.
Boats and ships turnover lock needs multiple orientation to command simultaneously, coordinate operation, existing mode is exchanged by mobile phone or public address equipment between person on duty with person on duty, long-time use mobile phone can produce the communication cost of great number, and on-the-spot noise is large, and communication effect is poor, existing public address equipment can only be propagandaed directed to communicate by the microphone in Sentry Box, during real work, person on duty often will leave Sentry Box to floor manager, and therefore the use of existing public address equipment is restricted.
Summary of the invention
In order to solve the defect that above-mentioned prior art exists, the utility model provides a kind of ship lock wireless talkback public address system.
The technical solution adopted in the utility model: a kind of ship lock wireless talkback public address system, comprise transmitter and receiver, described transmitter comprises processor I, and the input of described processor I connects microphone, key control module and battery module respectively, and output connects a modulator; Described receiver comprises processor II, and the input of described processor II connects demodulator and stabilized voltage power supply respectively, and the output of processor II connects loudspeaker.
Preferably, described processor I and processor II adopt KT-68 type PCB assembly.
Preferably, the output of described processor II connects loudspeaker input by capacitor filter.
Preferably, described stabilized voltage power supply adopts 220V alternating current to convert 3.7V direct current to through transformer.
Preferably, described loudspeaker adopts Interm-120 type loudspeaker, and this loudspeaker has independent current source input.
The beneficial effects of the utility model: utilize KT-68 type PCB assembly to coordinate modulator, demodulator to realize the wireless use of existing public address equipment, when operator on duty is exchanged, Sentry Box need not be run to and use microphone call, the portable transmitter of direct use just can control on-the-spot loudspeaker arbitrarily and carry out propagandaing directed to communicate intercommunication, be conducive to field personnel's interactive communication, improve and put lock efficiency.
Accompanying drawing explanation
Fig. 1 is theory diagram of the present utility model.
Embodiment
Be below a specific embodiment of the present utility model, be now described further by reference to the accompanying drawings.
As shown in Figure 1, a kind of ship lock wireless talkback public address system, comprise transmitter, receiver and Control Room, described transmitter comprises processor I, the input of described processor I connects microphone, key control module and battery module respectively, and output connects a modulator; Described receiver comprises processor II, and the input of described processor II connects demodulator and stabilized voltage power supply respectively, and the output of processor II connects loudspeaker; Described Control Room comprises supervisory control comuter and call device, and described call device function is identical with transmitter.
In the present embodiment, described processor I and processor II adopt KT-68 type PCB assembly, this assembly is a kind of intercom personal module, and a pcb board is integrated with the intercom Common Components such as filter, amplifier, CPU, as long as connecting circuit can use to specifications.
The output of described processor II connects loudspeaker input by capacitor filter.
Described stabilized voltage power supply adopts 220V alternating current to convert 3.7V direct current to for receiver through transformer.
Watch-dog on Control Room computer and boats and ships carries out communication, can understand the information such as position, water level of boats and ships at any time, thus carries out overall scheduling.
Described loudspeaker adopts Interm-120 type loudspeaker, and this loudspeaker has independent external power supply, and during use, sound can reach 90 decibels, because ship lock site space is open, and the dispersion of loudspeaker installation site, therefore can not cause noise effect to staff.
During use, each person on duty is equipped with a transmitter, and receiver is arranged on each position of ship lock.During boats and ships turnover ship lock, person on duty carries out to ship lock scene commanding, dispatching, and when needs and other persons on duty link up, selects the receiver of relevant position to carry out amplifying intercommunication by key control module.Sound imports processor I into from transmitter microphone, sends by after modulators modulate, reduces acoustic information after the demodulator of receiver receives information, and is sounded by loudspeaker.
Staff in Control Room understands the every terms of information of boats and ships in real time by supervisory control comuter, carries out integrated scheduling to boats and ships turnover ship lock.
After application native system, the scope of activities of person on duty obtains expansion, and field personnel can real-time communication, understands mutual command scheduling intention in time, improves and put lock efficiency.
