A kind of two-way traffic lights
Technical field
The utility model relates to traffic lights field, specifically, relates to a kind of two-way traffic lights.
Background technology
Traffic lights are basic components of commander's road traffic, if traffic lights damage, cause traffic lights to lose command function, traffic can be caused chaotic greatly, bring great hidden trouble of traffic.Current traffic lights are all adopt independent red light, green light and amber light, not traffic lights for subsequent use, once some traffic lights damage, then do not have stand-by lamp to use, make traffic lights lose command function.
summary of the invention:
The technical problems to be solved in the utility model is to provide a kind of two-way traffic lights, affects road traffic commander after preventing traffic lights from damaging.
The utility model adopts following technical scheme to realize goal of the invention:
A kind of two-way traffic lights, comprise red light, amber light and green light, described red light, green light and amber light lead to and connect controller, described controller connection timer, it is characterized in that: described red light connects with red light for subsequent use and relay switch after being connected in series with red light current sensor more in the lump, described green light connects with green light for subsequent use and relay switch two after being connected in series with green light current sensor again.
As the further restriction to the technical program, described amber light connects with amber light for subsequent use and relay switch three after being connected in series with amber light current sensor again.
As the further restriction to the technical program, described controller connects wireless transmitter module.
As the further restriction to the technical program, described controller connect respectively with described relay switch one, relay switch two and relay switch three with the use of relay one, relay two and relay three.
As the further restriction to the technical program, described controller connects down counter, and described down counter connects display charactron.
As the further restriction to the technical program, described wireless transmitter module adopts GPRS module.
Compared with prior art, advantage of the present utility model and good effect are: red light current sensor of the present utility model, green light current sensor and amber light current sensor respectively collecting work current signal are sent to controller, when some current sensors should brightly be when corresponding current signal not detected at traffic lights, illustrate that these traffic lights break down, controller sends signal to corresponding relay, relay sends trigger pip, corresponding relay switch closes, corresponding traffic lights work for subsequent use, GPRS module sends failure message to remote control center simultaneously, inform managerial personnel's on-call maintenance.The utility model can ensure that traffic lights are in good running status always, prevents traffic lights from damaging and causes traffic disturbance, ensure the good operation of road traffic, ensured the life security of pedestrian.

Embodiment:
Below in conjunction with embodiment, further illustrate the utility model.
See Fig. 1-Fig. 3, the utility model comprises red light 1, amber light 3 and green light 2, described red light 1, green light 2 and amber light 3 connection control device, described controller connection timer, to connect with red light 4 for subsequent use and relay switch 1 again after described red light 1 is connected in series with red light current sensor 8, connect with green light 5 for subsequent use and relay switch 2 12 again after described green light 2 is connected in series with green light current sensor 9.
Connect with amber light 6 for subsequent use and relay switch 3 13 again after described amber light 3 is connected in series with amber light current sensor 10.
Described controller connects wireless transmitter module.
Described controller connect respectively with described relay switch 1, relay switch 2 12 and relay switch 3 13 with the use of relay 1, relay 2 16 and relay 3 17.
Described controller connects down counter, and described down counter connects display charactron 18.
Described wireless transmitter module adopts GPRS module, for sending the failure message of traffic lights.
Workflow of the present utility model is: red light current sensor 8 of the present utility model, green light current sensor 9 and amber light current sensor 10 respectively collecting work current signal are sent to controller, when some current sensors should brightly be when corresponding current signal not detected at traffic lights, illustrate that these traffic lights break down, such as, when red light 1 should bright time, red light current sensor 8 does not collect current signal, illustrate that red light 1 breaks down, controller sends signal to corresponding relay 1, relay 1 sends trigger pip, corresponding relay switch 1 closes, corresponding red light for subsequent use 4 works, GPRS module 14 sends failure message to remote control center simultaneously, inform managerial personnel's on-call maintenance.In like manner, the process of enabling of green light for subsequent use and amber light for subsequent use and the process of enabling of red light for subsequent use duplicate, and do not repeat them here.Timer is used for sending trigger pip to controller, and timing when down counter is bright from signal lamp, along with passage of time is successively decreased gradually, until be decremented to 0.
