Description

Travel alarm for telephone supervision

The utility model relates to the communication communication of railway traffic management.Particularly a kind of supervision, the driving phone supervision warning device of supervising station driving person on duty to work, driving night shift room in station is used with the phone of driving a vehicle in the middle of being useful in.

The phone of railway station driving at present uses the unified phone of the Ministry of Railways to concentrate platform, should concentrate platform when receiving the contiguous station driving of uplink and downlink phone, ring, corresponding indicator light is bright, this can satisfy the needs that transportation is produced in the ordinary course of things, but it is absent-minded that the person on duty who meets goes to work, even the night shift drowsiness, can't hear ring, certainly will affect adversely and answer the driving phone, thereby influence normal transport, even cause driving accident, bring about great losses for country, the people.In addition,, do not have monitoring apparatus again, can't examine, bring difficulty to management work to Platform attendant work because night is on duty separately.

The purpose of this utility model provides and a kind of the person on duty received calls at the appointed time, can write down the person on duty again automatically and receive calls soon, the driving phone supervision warning device of slow situation.The utility model is provided with adjustable giving of time and reports to the police and strong alarm call, is enough to make the person on duty to wake up with a start from dream; Be provided with counting circuit, can write down alarm times automatically, be convenient to person on duty's work is examined; Be provided with nickel-cadmium cell, even make correct, complete that counting circuit also can guarantee to count when AC dump.The utility model volume is little, cost is low, timing accuracy is high, uses very convenient.The utility model self-organizing system does not influence the use that phone is concentrated platform.

Task of the present utility model is finished with following method: by sound, light probe and to trigger the driving phone supervision warning device that critical pieces such as amplifying circuit, logic switch, trigger switch, crystal oscillator, frequency divider, two timer, police whistle sound generation phone, warning amplifier, counter, loudspeaker form be to utilize the driving phone to concentrate the sound of platform, light by probe, through sound, light amplification triggering logic switch.The master oscillator frequenc of crystal oscillator is 32768HZ, produces the 2HZ signal through 14 frequency divisions, and the gate circuit of forming through frequency division and transistor is exported the signal of 30 seconds and 6 seconds respectively again.When sound, light probe obtain signal simultaneously, logic switch is opened, and drive trigger switch, make 30 seconds and 6 seconds signals are input to respectively through trigger switch and give alarm timer and strong alarm timer, report to the police when being timed to when giving, police whistle sound generation circuit working also amplifies through giving the warning amplifier, drives loudspeaker, sends the police whistle sound that slightly rings.When giving warning after some seconds, after the timing of reporting to the police was by force arrived, relay cut off and gives the warning amplifier, connects strong warning amplifier, makes loudspeaker send the police whistle sound of strong stimulation, and unison counter advances one automatically, the record alarm times.The utility model circuit is stable, and reliable working performance can supervise the person on duty in time to answer the driving phone, can investigate the situation of person on duty's work again from strong alarm count, helps traffic safety and driving management.
