Description
Technical field
The warning lamp system that the present invention relates to warning lamp and be connected with a plurality of warning lamps.
Background technology
Conventionally, the emergency vehicles such as fire fighting truck and emergency tender are noted in order to arouse pedestrian around and the driver of driving vehicle, astigmatic formula warning lamp are installed on roof face.Toward contact at bumper, side, a plurality of warning lamps are installed below.In addition, emergency vehicle is provided with for making the controllers such as warning amplifier of astigmatic formula warning lamp and warning lamp work near driver's seat.
In making the luminous method of a plurality of warning lamps, the method that is known to make the independent and single movement of each warning lamp with will store light-emitting mode and/female warning lamp in the luminous moment (claiming " illuminated message " below) is connected by signal line with a plurality of sub-warning lamps, the method that sub-warning lamp and the signal of exporting from female warning lamp are synchronously linked.Here female warning lamp refers to the warning lamp that makes synchronous synchronizing signal of luminous moment of connected warning lamp according to own synchronizing signal output, and sub-warning lamp refers to reception synchronizing signal and carries out luminous warning lamp based on this signal.
The frame structure that makes the independent also warning lamp system 60 of single movement of each warning lamp in the past as shown in Figure 6.This warning lamp system 60 comprise for control the controller 62 of warning lamp 63,64,65 with for being connected the signal line 61 of warning lamp 63,64,65 and controller 62.Signal line 61 couples together controller 62 and warning lamp 63,64,65.Controller 62 has the system start-up operation switch 62a that makes warning lamp 63,64,65 start and stop.Warning lamp 64 has signal input part 64a, the 64b of light emitting control portion, illuminating part 64c and storage part 64d.In addition, although only the inside of warning lamp 64 is formed and is illustrated for convenience of explanation, warning lamp 63,65 also has respectively identical formation.
In this warning lamp system 60, by os starting console switch 62a, enabling signal is input to warning lamp 63,64,65 via signal line 61, and each 63b of light emitting control portion, 64b, 65b read illuminated message and start luminous to illuminating part 63c, 64c, 65c indication from storage part 63d, 64d, 65d separately.
Because these warning lamps 63,64,65 have identical structure, so as long as prepare the warning lamp of identical function, just can construct and take enabling signal and make each warning lamp start luminous warning lamp system 60 as triggering.In addition, though due to the broken string of fault or signal line cause specific warning lamp for example warning lamp 63 do not work, other warning lamp 64,65 also can carry out luminous.
Next, Fig. 7 has represented to use the frame structure of other warning lamp systems 70 of warning lamp in the past.In addition, for convenience of explanation, to describing from the effect shown in Fig. 6, part that structure is different, and omitted for identical effect, structure.This warning lamp system 70 comprises: for controlling the controller 72 of warning lamp 73,74,75; Warning lamp 73,74,75; For connecting the signal line 71 between controller 72 and each warning lamp 73,74,75.Signal line 71 is by the control signal circuit 71a that controller 72 is connected with warning lamp 73,74,75 and will warn 73,74,75 interconnective synchronizing signal circuit 71b and form.
The signal input and output 73a of portion makes warning lamp 73 actions via the system start-up operation switch 72a of control signal circuit 71a operation control 72.The 73b of light emitting control portion reads illuminated message from storage part 73d makes illuminating part 73c luminous.In addition, from the signal input and output 73a of portion, via synchronizing signal circuit 71b, to handset warning lamp 74,75, export synchronous control signals (its flesh and blood is illuminated message).
In this warning lamp system 70, machine tool warning lamp 73 is exported the illuminated message as synchronous control signal from the signal input and output 73a of portion, and being input to handset warning lamp 74,75 via synchronizing signal circuit 71b, the handset warning lamp 74,75 that has received the input of synchronous control signal utilizes the 74b of light emitting control portion, 75b to make illuminating part 74c, 75c according to luminous from the illuminated message of machine tool warning lamp 73 outputs.
Therefore, the difference in the luminous moment that this warning lamp system 70 produces for the individual difference preventing due to the performance of each warning lamp, makes the illuminated message synchronous light-emitting of handset warning lamp and synchronizing signal as from the output of machine tool warning lamp.In addition, due to machine tool warning lamp and handset warning lamp synchronous light-emitting, so can prevent that the luminous of each warning lamp from sending confusedly.Thus, can utilize synchronous light-emitting to make to irradiate light and be rich in one sense, and improve visibility.
Patent documentation 1: Japanese kokai publication hei 09-306208 communique.
Yet in warning lamp system 60, warning lamp 63,64,65 is poor according to the individual difference of its performance, the luminous moment is slightly different.Therefore, luminous even if warning lamp 63,64,65 starts by os starting console switch 62a, the luminous moment of each warning lamp staggered along with the time, became scatteredly luminous.Therefore, be relatively difficult for the light that sends depending on recognizing than synchronous light-emitting, existence can not be guaranteed the unfavorable condition of travelling of emergency vehicle safely.
In addition, although warning lamp system 70 can make warning lamp 73 for machine tool and make warning lamp 74,75 synchronous light-emittings, but if warning lamp 73 breaks down, the 74b of light emitting control portion, 75b are judged as does not have the input of synchronous control signal and stops luminously, so warning lamp 74,75 does not work yet.In addition,, in the situation of synchronizing signal electric wire 71b broken string, the warning lamp after broken string place does not work.Therefore, exist the pedestrian of surrounding of emergency vehicle or the driver of vehicle just to perceive very late approaching of emergency vehicle etc. and can not fully guarantee safe unfavorable condition.
Summary of the invention

Embodiment
Fig. 1 is the block diagram of execution mode of warning lamp system that has used the warning lamp of the present application.
This warning lamp system have the light that gives a warning a plurality of warning lamps 3,4,5 (quantity of warning lamp is not limit, in the present embodiment for " 3 "), for controller 2 that each warning lamp 3,4,5 is controlled and be arranged on each warning lamp and controller 2 between signal line 1.
Signal line 1 comprises and connects the control signal circuit 1a of controller 2 and each warning lamp 3,4,5 and by interconnective synchronizing signal circuit 1b between individual warning lamp 3,4,5.Signal line 1 can be Wireline as illustrated, can also be to take electric wave or light to communicate the radiolink of use as media.
Below, represent warning lamp 3,4,5, warning lamp 4 is described.Other warning lamps 3,5 are also identical structure.Warning lamp 4 has the signal input and output 4a of portion, the 4b of light emitting control portion, illuminating part 4c, storage part 4d, the 4e of timing portion, also comprises siren amplifier.
Illuminating part 4c is by being arranged on auxiliary warning lamp on the bumper of vehicle or the side face of vehicle, in rear aspect, forming with the astigmatic formula warning lamp etc. that is arranged on the end face of vehicle.
The signal interface portion performance of the signal input and output 4a of portion function, carries out (being called the input and output of " synchronous control signal " below, for reaching the signal of synchronizeing with other warning lamps 3,5 via synchronizing signal circuit 1b.In addition, from controller 2 via control signal circuit 1a to the signal input and output 4a of portion input for the signal that makes warning lamp 4 start and stop (below claim " actuating signal ".In addition, in the present embodiment, for the signal that illuminated message (following) is changed, also via synchronizing signal circuit 1b, be transmitted.
The 4b of light emitting control portion makes illuminating part 4c luminous according to the illuminated message (following) that is input to the synchronous control signal of the signal input and output 4a of portion and read out from storage part 4d.
It is luminous that illuminating part 4c stipulates by the control of the 4b of light emitting control portion, by light-emitting diode (claiming " LED " below) group, waits light source to form.
The 4e of timing portion sets for judging whether to have inputted from other warning lamps 3,5 time (below be called " trusted stand-by time T ") of synchronically controlling information.
In addition, warning lamp 4 has: make synchronously luminous " machine tool pattern " of illuminating part 4c and the own synchronous control signal of exporting; The synchronous control signal of exporting with the warning lamp in other machine tool patterns synchronously carries out light emitting control, makes illuminating part 4c luminous " handset control model "; The operate condition of " state does not work " 3 classes.Illuminated message in front 2 class patterns is stored in aforesaid storage part 4d.
Below, the action of each warning lamp of this warning lamp system is described according to Fig. 1 and Fig. 2.
Fig. 2 means the flow chart of the action of each portions such as the signal input and output portion, light emitting control portion, timing portion of warning lamp 4.Other warning lamps 3,5 also carry out identical action in addition.Here, take warning lamp 4 as object, its action is described.
In the initial condition (before power supply access) of warning lamp 4, because warning lamp 4 is not set at machine tool pattern or in the action of handset pattern, moves so use described algorithm to be set in which pattern.
First, if system start-up operation switch 2a is operated, actuating signal is imported into warning lamp 4 via control signal circuit 1a, and warning lamp 4 starts the setting of machine tool pattern/handset pattern and processes (step S1).The 4b of light emitting control portion is after system start-up operation switch 2a is operated, the 4e of timing portion is set to trusted stand-by time T, than the cycle N of the synchronous control signal of the warning lamp output in machine tool pattern, (value of N is given constant in system to this trusted stand-by time T, the amount of all knowing in advance for each warning lamp.) long (step S2).That is, N < T sets up.
This trusted stand-by time T is the incoherent time between warning lamp 3,4,5.Trusted stand-by time T is such as can be according to the settings such as random number that produce in the 4e of timing portion.In addition, as other example, the 4e of timing portion is in nonvolatile memory, corresponding to " 1,2,3 ... " etc. the mutual different trusted stand-by time T of number storage, during every setting trusted stand-by time T mono-time, above-mentioned number is added to 1, set the trusted stand-by time T corresponding with this number (if number is taken turns through, returning to initial number).
Warning lamp 4 judgements have or not the input (step S3) of synchronous control signal in trusted stand-by time T.Because trusted stand-by time is according to settings such as random numbers, so can avoid the trusted stand-by time of warning lamp 3,4,5 to be set to same time with high probability.
If warning lamp 4 is not inputted synchronous control signal in trusted stand-by time T, be judged as in other warning lamps of its connection and do not have the warning lamp just moving in machine tool pattern, as input synchronous control signal, be judged as and in other warning lamps of its connection, have the warning lamp just moving in machine tool pattern.Like this, warning lamp 4, by the processing of step S2, step S3, can judge whether to exist the warning lamp (being equivalent to " machine tool search is processed ") just moving in machine tool pattern.
If there is not the warning lamp in machine tool pattern in the warning lamp connecting, warning lamp 4 self is exported synchronous control signal (step S4).And, if the output at synchronous control signal has been transfused to the synchronous control signal (that is, clashing between synchronous control signal) (step S5 is) from other warning lamps simultaneously, again return to machine tool search and process (step S2, step S3).If be not transfused to the synchronous control signal from other warning lamps in the output of synchronous control signal, warning lamp 4 carries out action (step S6) afterwards as the warning lamp of machine tool pattern.
In addition, in step S3, if inputted synchronous control signal in trusted stand-by time T, be judged as the warning lamp having in the action of machine tool pattern in other warning lamps that connect, and the warning lamp in handset pattern moves (step S7) using its oneself warning lamp.
In addition, the action of this new warning lamp when this warning lamp system has been appended to new warning lamp, describes according to Fig. 2.New warning lamp is connected with this warning lamp system, and at its power connection and start after basic software (OS), (step S1) processed in the setting that starts machine tool pattern/handset pattern, setting trusted stand-by time (step S2).Then, that new warning lamp is received in is that existing system is just moving, the synchronous control signal of the warning lamp output in machine tool pattern, and moves (step S3 → step S7) as handset pattern.
As described above, each warning lamp does not have the difference of machine tool handset when initial condition, and which in machine tool, handset pattern its input according to synchronous control signal decide with and move.As its effect, can in the management of this warning lamp system, not carry out the confirmation of machine tool and handset and easily carry out appending and changing of warning lamp.In addition, once if by the power reset of warning lamp, the machine tool being set and the action of handset are also reset, so can easily reset.
Next, the action to the warning lamp 3,4,5 after the power supply access of this warning lamp system, describes according to Fig. 2 and Fig. 3.In Fig. 3, the output waveform of the synchronous control signal of warning lamp 3 outputs is made as to OP3, the input waveform of the synchronous control signal of warning lamp 3 inputs is made as to IP3, the luminescent waveform of warning lamp 3 is made as to S3.In addition, also identical for warning lamp 4,5.
First, if system start-up operation switch 2a is operated, actuating signal is imported into each warning lamp via control signal circuit 1a, and each warning lamp starts the setting of machine tool pattern/handset pattern and processes (the step S1 of Fig. 2).That is, each light emitting control portion, according to the input of described actuating signal, sets for judging whether the warning lamp of connection has the trusted stand-by time of the warning lamp in machine tool pattern.The trusted stand-by time that warning lamp 3 is set is made as to t3, the trusted stand-by time that warning lamp 4 is set is made as to t4, the trusted stand-by time that warning lamp 5 is set is made as to t5 (step S2).Next, warning lamp 3,4,5 judges have or not (the step S3) in the input of trusted stand-by time t3, t4, t5 inter-sync control signal.
Owing to not exporting the warning lamp of synchronous control signal in other warning lamps that connect, so warning lamp 3 is exported synchronous control signal (step S4) in through trusted stand-by time t3.If confirmed not have the conflict of synchronous control signal, in other warning lamps that judgement connects, there is no machine tool warning lamp (step S5), warning lamp 3 starts machine tool pattern (step S6).The warning lamp 3 that has started machine tool pattern makes illuminating part 3c luminous according to the illuminated message being stored in storage part 3d, correspondingly exports synchronous control signal.
Warning lamp 4 has been transfused to the synchronous control signal of warning lamp 3 outputs in the trusted stand-by time t4 being set, thereby warning lamp 4 starts handset pattern.Meanwhile remove the timing action of the trusted stand-by time t4 of the 4e of timing portion.In the input of the synchronous control signal after trusted stand-by time t4, make illuminating part 4c luminous (step S3 → step S7).For warning lamp 5, be also the handling process identical with warning lamp 4, it starts handset pattern.
As described above, do not waiting until that trusted stand-by time T is through removing trusted stand-by time with regard to having inputted the moment of synchronous control signal, if be not remove in order to prevent, trusted stand-by time T through constantly, warning lamp 4,5 is thought by mistake and is ownly started the output of synchronous control signal for machine tool.
In addition, by manager, the luminescence control switch 2 of controller 2 is operated, the illuminated message of warning lamp 3,4,5 can be changed together.For example, can be by every 0.1 second 3 times and take that to be the cycle luminous in 1 second and change to every 0.3 second 2 times and take that to be the cycle luminous in 1.5 seconds.
Next, for the warning lamp of the machine tool pattern operation as this warning lamp system break down, the action of the warning lamp of handset pattern during electric wire etc., according to Fig. 2 and Fig. 4, describe.If the warning lamp of machine tool pattern is warning lamp 3.
The warning lamp 4,5 of handset pattern and synchronously carry out luminous (step S6, step S7) by the synchronous control signal that the synchronous control signal of the warning lamp 3 in machine tool pattern is inputted the warning lamp 4,5 of handset pattern.In addition, the warning lamp 4 in handset pattern starts to start at from the input time of synchronous control signal IN4, sets trusted stand-by time t4 (step S2).In addition, the warning lamp in handset pattern 5 is set trusted stand-by time t5 (step S2).Here, the trusted stand-by time t4 < t5 having set.In addition, as described above, trusted stand-by time t4, t5 are than the long time of cycle N of the synchronous control signal of warning lamp 3 outputs in machine tool pattern.
Yet, suppose fault due to the warning lamp 3 in machine tool pattern, broken string etc., can not export synchronous control signal OP3 (in Fig. 4 with dotted line and * mark represents).
Because warning lamp 4 is not inputted synchronous control signal in its trusted stand-by time t4, so be judged as the warning lamp just not moving in machine tool pattern in other warning lamps of connection, warning lamp 4 is exported synchronous control signal (step S4) in trusted stand-by time t4 process.
If there is no the input (being the conflict of synchronous control signal) of other synchronous control signals in this synchronous control signal output, be judged as in the warning lamp of connection and there is no machine tool warning lamp (step S5), warning lamp 4 is own carries out later action (step S6) as the warning lamp in machine tool pattern.
The warning lamp 4 that has started machine tool pattern makes illuminating part 4c luminous according to the illuminated message being stored in storage part 4d, and correspondingly carries out the output of synchronous control signal.
Warning lamp 5 receives the control signal same period of warning lamp 4 outputs in trusted stand-by time t5, and starts handset pattern, makes illuminating part 5c luminous (step S3, step S7) in the input of the synchronous control signal after trusted stand-by time t5.
In addition, there is the warning lamp 3 of fault owing to not having via synchronizing signal circuit 1b input and output synchronous control signal in the signal input and output 3a of portion, so be the judgement of "No" in step S3, step S5 always, warning lamp 3 continues machine tool pattern (step S6).Thereby that carries out not synchronizeing with warning lamp 4,5 is luminous.
The action of the warning lamp 4,5 while next, a plurality of warning lamps being started to the output of synchronous control signal simultaneously describes according to Fig. 2, Fig. 5.In Fig. 5, establish warning lamp 3 for machine tool pattern, warning lamp 4,5 is handset pattern.
Handset warning lamp 4,5, by the triggering that is input as of synchronous control signal, is set trusted stand-by time t4a, t5a, and timing respectively.If now the synchronizing signal circuit 1b of the warning lamp 3 of machine tool pattern breaks.Trusted stand-by time t4a, the t5a of handset warning lamp 4,5 are accidentally set as same time.
If be not transfused to synchronous control signal (step S3 is no) in the trusted stand-by time t4a, the t5a that set, due to t4a=t5a, so handset warning lamp 4,5 is exported synchronous control signal (step S4) simultaneously.Handset warning lamp 4,5 receives respectively the input IP4,5 (step S5) of synchronous control signal in the output OP4,5 of synchronous control signal.Therefore, handset warning lamp 4 is using the input IP4 of this synchronous control signal as triggering, again set trusted stand-by time (step S2), handset warning lamp 5, using the input IP5 of this synchronous control signal as triggering, is set trusted stand-by time (step S2) again.The trusted stand-by time of again setting is made as respectively to t4b, t5b.The trusted stand-by time t4b setting is shorter than trusted stand-by time t5b.
Warning lamp 4,5, in the trusted stand-by time t4b, the t5b that again set, judges that having or not of synchronous control signal is transfused to (step S3).First, due to process trusted stand-by time t4b, warning lamp 4 output synchronous control signals (step S4).Secondly, warning lamp 4 confirms do not have after the conflict (step S5 is no) of synchronous control signal, is judged as in the warning lamp of connection and there is no the warning lamp of machine tool pattern, and start machine tool pattern, and make illuminating part 4c luminous (step S6).Warning lamp 5 starts handset pattern according to inputted the synchronous control signal of being exported by warning lamp 4 in trusted stand-by time t5, and in the input of the synchronous control signal after trusted stand-by time t5, make illuminating part 5c luminous (step S3, step S7).
In addition, warning lamp 3 is due to control signal circuit 1b broken string, so input and output that can not synchronous control signal are the judgement of "No" at step S3, step S6 always, and its lasting machine tool pattern (step S6).Thereby, synchronously do not continue luminous with warning lamp 4,5.
In addition, in the warning lamp system of present embodiment, in the input (IP4) of the synchronous control signal of warning lamp 4 before the trusted stand-by time t4 through for example Fig. 3, start handset pattern, in the input (the 2nd IP4) of the synchronous control signal through after trusted stand-by time t4, make illuminating part 4c luminous.But not necessarily need in the input of synchronous control signal, make illuminating part 4c luminous.Can also in the end of input (representing with the t41 of Fig. 3) of synchronous control signal, start machine tool control model.
And the warning lamp that also can become machine tool pattern can read out the output that illuminated message is carried out synchronous control signal from storage part, and the illuminated message of other warning lamp is changed.By change illuminated message, can identify from outside its variation.Therefore, can find in early days the fault of warning lamp, the broken string of signal line etc., thereby can carry out emergency maintenance.
Effect below can obtaining in this warning lamp system of above-mentioned explanation.The warning lamp of handset pattern judges the input of the synchronous control signal of the warning lamp output in machine tool pattern, when the warning lamp in machine tool pattern breaks down, oneself just becomes machine tool pattern and move.Thus, can control the synchronous light-emitting of each warning lamp is continued.Therefore, even if installed on the emergency vehicle of for example setting out in the situation of each warning lamp together, also can prevent that each warning lamp is scatteredly luminous, by synchronous light-emitting, make to irradiate light and be rich in one sense, thereby can improve visibility, more can call attention to.
In addition,, in the step S2 of Fig. 2, by setting trusted stand-by time T, avoided warning lamp unconsciously to start machine tool pattern.If each warning lamp starts machine tool pattern, each warning lamp is exported synchronous control signal simultaneously, can not reach luminous synchronous.The present invention can prevent such state of affairs.In addition, in step S6, by reaffirming having or not of synchronous control signal, even if suppose at the identical warning lamp of trusted stand-by time to be that synchronous control signal clashes when more than 2, also can avoid 2 above warning lamps to become machine tool pattern by further again setting trusted stand-by time simultaneously.
