Abstract
The utility model discloses a tunnel signal emission device, which comprises at least two radio signal emitters for alternately emitting signals, each of which has a certain proportion of a signal emission time and a standby time. The tunnel signal emission device provided in the utility model uses two signal emitters to alternately emit radio signals with the same frequency, both of which adopt the operation mode of 3-second operation followed by 9-second standby, so as to solve the high energy consumption and high heat generation amount problems in tunnel signal emission. Meanwhile, the two signal emitters alternately operate with only 3-second interval standby, so as to ensure the operational reliability of the entire signal emission device.
Description
Technical field
The utility model relates to a kind of sender unit, relates in particular to the tunnel signal emitter.
Background technology
At present, realize that the signal method for transmitting generally has following four kinds, both radio, infrared ray, ultrasonic wave and microwave etc.Wherein, the necessary straightline propagation of infrared ray is difficult to realize under emission and all uncertain situation of receiving terminal; Ultrasonic wave and microwave are easy to be reflected by object, and penetrability is poor, and it often applies to detect moving object.So, in constructing tunnel, adopt the remote control system of radio signal emission, in the mutual police who realizes between transporting equipment and implement and workmen, be the optimal selection in the present shield-tunneling construction.
Yet,,, could realize the emission of distant signal so the radio signal emitted power must be enough because constructing tunnel is to carry out in airtight relatively space.Chinese patent 95241695.6 provides and has been used for the radio transmitting apparatus of train near early warning, and still, this sender unit exists energy consumption higher, and caloric value is big, works long hours easily to cause heating burnout the problem that working life is short.
The utility model content
The technical problems to be solved in the utility model provides a kind of tunnel signal emitter, and this tunnel signal emitter energy consumption is low, caloric value is little, reliable operation.
In order to solve the problems of the technologies described above, the utility model tunnel signal emitter adopts following technical scheme: comprise the radio-signal transmitter that signal transmission time and free time are proportional, described radio-signal transmitter is the radio-signal transmitter that at least two groups alternately transmit.
Described radio-signal transmitter is two groups.The signal transmission time of described two groups of radio-signal transmitter and the ratio of free time are 1: 3.Described radio-signal transmitter signal transmission time is 3 seconds, and free time is 9 seconds.What described radio-signal transmitter alternately transmitted is spaced apart 3 seconds.Also comprise a controller that is connected with described radio-signal transmitter.
The tunnel signal emitter that the utility model provides, adopt two signal projectors to replace the output frequency same wireless signal of telecommunication, and the mode of operation that all adopts work to have a rest for 9 seconds for 3 seconds, solved in the tunnel signal emission long, the big big problem of energy consumption height, caloric value that produces of power of time.Simultaneously, because two signal projector alternations, it was 3 seconds only at interval, had guaranteed the reliability of whole sender unit work.
Below in conjunction with accompanying drawing the utility model tunnel signal emitter is elaborated.
Description of drawings
Fig. 1 is the circuit structure block diagram of the signal projector of the utility model tunnel signal emitter;
Fig. 2 is the operation principle schematic diagram of the utility model tunnel signal emitter.
Embodiment
As shown in Figure 1, the signal projector of the utility model tunnel signal emitter comprises main shake three grades of frequency multiplier circuits 1, power amplifier 2 and transmitting antenna 3.Wherein, the main three grades of frequency multiplier circuits 1 that shake produce a high-frequency signal by capacitance connecting three point type oscillator 11, after buffer amplifier 12 bufferings are amplified, input is penetrated grade follower 13 and is carried out two frequencys multiplication, input switch triode 14 carries out frequency tripling afterwards, again after power amplifier 2 amplifies, to the frequency of transmitting antenna 3 output 315MHZ.
Embodiment as shown in Figure 2, the utility model tunnel signal emitter is made up of signal projector 1A and the 1B shown in two picture groups 1, and reflector 1A is connected via a controller with 1B.The frequency that signal projector 1A transmits is, signal projector transmitted after the 1A1 section time, the rest 1A2 section time.The frequency that signal projector 1B transmits is, signal projector transmitted after the 1B1 section time, the rest 1B2 section time.Wherein, 1A1 and 1B1 section time were respectively for 3 seconds, and 1A2 and 1B2 section time were respectively for 9 seconds.Therefore, the time interval that signal projector 1A and 1B transmit is the R section time shown in Figure 2, and this section period is 3 seconds.Described signal projector 1A and 1B, the frequency of its antenna output is 315MHZ.Because, signal projector 1A is connected by controller with 1B, can control signal transmitter 1A and blanking time of 1B signal emission by this controller, and the output frequency of signal projector 1A and 1B is identical, and the mode of operation that all adopts work to have a rest for 9 seconds for 3 seconds, solved in the tunnel signal emission long, the big big problem of energy consumption height, caloric value that produces of power of time.Simultaneously, because two signal projector alternations, it was 3 seconds only at interval, had guaranteed the reliability of whole sender unit work.
Two groups of signal projectors have guaranteed that the signal of emission maintains 3 seconds durations in the space, have duty ratio and be 1: 1 signal square wave, for the diesel vehicle or battery vehicle of constructing tunnel, have guaranteed fail safe on the speed fully.Even gone bad one group, also have another group in addition, mentioned reliability greatly in work.During maintenance, just can know whether one group of damage, also guarantee the convenience of maintenance as long as the maintenance personal sees the alert frequency of alarm.Because shield machine is also at narrow and small tunnel space, its electromagnetic radiation is also very big, often influence the stability that receives, it is exactly the shake that we say at ordinary times, now just can successfully go to tremble for this problem with 555 time-base circuits, and the time debugging is simple, circuit is simple, can not need to take the too many expensive real estate of alarm.
Shown in Figure 2 only is the preferred embodiment of the utility model tunnel signal emitter, the utility model can adopt the pattern of 3 signal projector shown in Figure 1 alternations simultaneously fully, under this pattern, with regard to the blind area that does not exist two signal projectors all to have a rest.But the sender unit of three signal projector compositions can exist to be made and the high problem of maintenance cost.
In addition, under the pattern that adopts two signal projector work, can also eliminate the work blind area by adjusting the time span of each signal projector work.But the utility model mainly is to be conceived to the tunneling shield construction environment, for the collision of avoiding transporting equipment, implement and staff is provided with, has certain blanking time, can satisfy the needs of use fully.
Above disclosed only is preferred embodiment of the present utility model, can not limit the interest field of the utility model certainly with this, and therefore the equivalent variations of being done according to the utility model claim still belongs to the scope that the utility model is contained.
