The control module sends a driving signal when the signal component displays the driving light signal. The control module displays the driving signal when the signal component displays the driving signal. The stop signal sends out a stop signal, and the control module sends out a position signal of the position of the signal component; and a push module is connected to the control module, and the push module Push the driving signal, the stopping signal, and the position signal within a push range; and a first mobile device for use by a passerby, the first mobile device is wirelessly connected to at least one The control device further includes: a first subscription module capable of subscribing to the driving signal, the stopping signal, and the position signal pushed by the push module within the push range; and a first notification module connected to the first subscription module. The first notification module displays the location of the control module based on the location signal. The first notification module displays the location of the control module based on the driving The signal and the stop signal inform the pedestrian that the signal component is currently the running light signal or the stop light signal.

The push range referred to here refers to a predetermined range that the push module 12 can transmit and receive. Of course, the push range can also be actively restricted. For example, the maximum transmission and reception range of the push module 12 is 10 meters in radius, but the push module 12 is restricted by a person with higher authority. Can only receive a radius of 5 meters.

It is worth noting that FIG. 2 is a schematic diagram of the control device 1 in this embodiment using a lamp holder structure, and the signal assembly 200 in the figure omits components such as a lampshade, a rain shield, and a yellow light signal. As shown in Figure 2, the control module 11 in this embodiment is designed to have a plurality of lamp holder structures. Two lamp holder structures L1 and L2 will be used for description below, but the invention is not limited thereto. .

Specifically, the control module 11 includes a first controller 111 and a second controller 112. The push module 12 includes a first pusher 121 connected to the first controller 111 and A second pusher 122 is connected to the second controller 112, and the first controller 111 and the first pusher 121 are integrated into one lamp holder structure L1.

[Second Embodiment]

As shown in Figure 4, it is a traffic management system 100B according to the second embodiment of the present invention. This embodiment is similar to the traffic management system 100A according to the above-mentioned first embodiment. The similarities between the two embodiments will not be described again. The main difference between this embodiment and the traffic management system 100A of the first embodiment is that the control module 11 also includes a first timer 113 connected to the first controller 111 and a second timer 113 connected to the first controller 111 . A second timer 114 of the controller 112, the first timer 113 and the second timer 114 each have an on time period and an off time period, and the first timer 113 and the second timer 114 The two timers 114 can each time time independently, so that the first controller 111 and the second controller 112 can independently control according to the corresponding first timer 113 and the second timer 114 The red light signal 210 and the green light signal 220 .

Specifically, when the first controller 111 detects that the first timer 113 is in the on time period, the first controller 111 turns on the red light signal 210 . When the first controller 111 detects that the first timer 113 is in the off time period, the first controller 111 turns off the red light signal 210 . In addition, when the second controller 112 detects that the second timer 114 is in the on time period, the second controller 112 turns on the green light signal 220 . When the second controller 112 detects that the second timer 114 is in the off time period, the second controller 112 turns off the green light signal 220 . Wherein, the on time period of the first timer 113 is equal to the off time period of the second timer 114, and the off time period of the first timer 113 is equal to the second timer 113. The opening time period of 114.

To facilitate understanding, an example of practical application is given below, but the present invention is not limited thereto. Assuming that the on time period and the off time period of the first timer 113 are designed to be 60 seconds and 120 seconds respectively, then the on time period and the off time period of the second timer 114 will be designed as 120 seconds and 60 seconds respectively, which means the first timer 113 and the The second timers 114 each have a cycle of 180 seconds.

During operation, the first timer 113 and the second timer 114 can time independently after correcting each other's starting points (that is, they start timing after both zero seconds). The first controller 111 and the second controller 112 vary between 0 and 60 seconds (i.e., the first timer 113 The on-time period of 113 and the off-time period of the second timer 114 respectively turn on the red light signal 210 and turn off the green light signal 220, between 61 and 180 seconds (i.e., The off time period of the first timer 113 and the on time period of the second timer 114 respectively turn off the red light signal 210 and turn on the green light signal 220 .

Accordingly, in this embodiment, the first controller 111 and the second controller 112 of the control module 11 can independently time and control the red light signal 210 and the green light signal. 220, thereby avoiding traffic paralysis when one of the first controller 111 or the second controller 112 is damaged.

In addition, it is worth mentioning that in this embodiment, the control module 11 can use the first timer 113 and the second timer 114 to pair the corresponding first controller 111 and the The second controller 112 respectively sends a timing signal, so that the first pusher 121 and the second pusher 122 can respectively push the timing signal to the first mobile device 2, thereby providing Passers-by know the number of seconds the light signal of the signal component 200 changes.

Furthermore, in order to prevent the first timer 113 and the second timer 114 from being out of synchronization, there is a second confirmation between the first controller 111 and the second controller 112 design.

Specifically, the first controller 111 sends a red light off signal to the second controller 112 when the red light signal 210 is turned off. When 210 is turned on, a red light turn-on signal is sent to the second controller 112 . The second control The controller 112 sends a green light off signal to the first controller 111 when the green light signal 220 is off, and the second controller 112 sends a green light on signal to the third controller when the green light signal 220 is on. A controller 111.

When the second controller 112 detects that the second timer 114 is in the on time period and receives the red light off signal, the second controller 112 turns on the green light signal 220 . When the second controller 112 detects that the second timer 114 is in the off time period and receives the red light on signal, the second controller 112 turns off the green light signal 220 .

On the contrary, when the first controller 111 detects that the first timer 113 is in the on time period and receives the green light off signal, the first controller 111 turns on the red light signal 210 . When the first controller 111 detects that the first timer 113 is in the off time period and receives the green light on signal, the first controller 111 turns off the red light signal 210 .

Of course, the first controller 111 and the second controller 112 may also communicate with each other to achieve time synchronization between the first timer 113 and the second timer 114, that is, where One timer corrects another timer.

[Third Embodiment]

As shown in Figure 5, it is a traffic management system 100C according to the third embodiment of the present invention. This embodiment is similar to the traffic management system 100A according to the above-mentioned first embodiment. The similarities between the two embodiments will not be described again. The main difference between this embodiment and the traffic management system 100A of the first embodiment is that the traffic management system 100C also includes a plurality of control devices 1 and a cloud control center connected to the plurality of control devices 1 . 3. The cloud control center 3 can control the control module 11 of each control device 1 so that the corresponding signal component of each control device 1 200 switches the display between the driving light signal and the stop light signal.

That is to say, the traffic management system 100C in this embodiment is automatically or artificially controlled by the cloud control center 3. For example, the cloud control center 3 uses artificial intelligence calculations based on the relationship between traffic flow and time. (For example: automatic adjustment of signals based on big data based on trigger signals generated between subscription and reception, as a basis for traffic flow, or manual adjustment of signal changes. Among them, artificial intelligence calculations to adjust signals based on the relationship between traffic flow and time are existing technologies and will not be specifically introduced here.

In addition, in practice, the stop light signal can also be adjusted to a light signal with other functions depending on the situation. For example, certain types of vehicles can pass through at specific times, rockfall warnings, construction ahead, etc.

As shown in Figure 6, it is a traffic management system 100D according to the fourth embodiment of the present invention. This embodiment is similar to the traffic management system 100A according to the first embodiment. The similarities between the two embodiments will not be described again. The main difference between this embodiment and the traffic management system 100A of the first embodiment is that the traffic management system 100D also includes a second mobile device 4 wirelessly connected to the control device 1, and the second mobile device 4 It is suitable to be installed in a public vehicle (such as an ambulance or a police car), so that the personnel in the public vehicle can adjust the nearby signal assembly 200 .

Specifically, the second mobile device 4 includes a switching module 41 and a transceiver module 42 connected to the switching module 41 . The switching module 41 can be triggered (for example, pressed) by a person on the official vehicle and can send a forced switching signal to the transceiver module 42, so that the transceiver module 42 transmits the information via wireless communication. The forced switching signal is sent to the control module 11 so that the control module 11 controls the signal component 200 to switch from the driving light signal to the stop light signal or from the stop light signal. to the driving signal. That is to say, the switching module 41 can control the change of the light signal of the signal component 200 .

In addition, in a preferred case, when the control module 11 receives the forced switching signal, the push module 12 can push an official signal to the first subscription module 21 in the push range. . The first notification module 22 notifies the passer-by based on the official signal that the official vehicle is currently sending the forced switching signal, thereby allowing the passer-by to evaluate the road usage pattern.

For example, when an ambulance is performing a mission, the ambulance personnel can activate the switching module 41 to send out the forced switching signal, so that the signal component 200 controlled by it can forcibly switch the light signal, so that the ambulance mission can go smoothly. Finish. At this time, the first mobile device 2 will also receive the official signal at the same time, thereby informing the passerby that there is a rescue mission at this time, causing the signal component 200 to be forced to switch the light signal.

Of course, in other embodiments not shown, the control module 11 can also control the signal component 200 to generate special light signal changes when receiving the forced switching signal, for example: using multiple LED lights. The signal displays an ambulance or a warning pattern, so that passers-by can directly learn the situation through the signal component 200 .

In addition, in other embodiments, the second mobile device 4 also has a subscription function of the first mobile device 2, so that people on the official vehicle can also know the status of the surrounding signal components 200. , which means that the second mobile device 4 also includes a second subscription module 43 and a second notification module 44 connected to the second subscription module 43, and the second subscription module 43 and the The connection and working mode of the second notification module 44 are generally the same as the first subscription module 21 and the first notification module 22 of the first mobile device 2 and will not be specifically introduced here.
