Abstract

An infrared train approaching early warning system includes a first infrared receiver, a first infrared transmitter, a second infrared transmitter, a first processor and an alarm. The first infrared transmitter and the second infrared transmitting unit respectively transmit a first infrared ray and a second infrared ray toward the first infrared receiver. When the first processor determines that the first infrared receiver has not received the first infrared ray and the second infrared ray in sequence within a first time, the first processor generates a first alarm signal and transmits the first alarm signal to the alarm. When the alarm receives the first alarm signal, the alarm generates a first alarm prompt. In this way, when a train passes the setting position of the first infrared receiver, the alarm will issue a first alarm prompt to remind construction personnel to pay attention and avoid danger.

Description

Infrared train approaching warning system

The invention relates to an early warning system, in particular to an infrared train approaching early warning system.

When a train is running on the railway, if an emergency occurs, the train driver usually does not have time to brake. Railroad construction workers need to perform maintenance on the rails. When a train passes by, they need to remind the maintenance workers working on the rails in advance so that they can evacuate in advance to avoid accidents. Therefore, railroad maintenance work is a job with an extremely high risk factor.

The current method of reminding railroad construction workers is to set up sentry posts at a safe distance from the work area and arrange lookouts to observe whether there are trains approaching. When a train is observed approaching, the lookouts are set up as soon as possible to remind the construction workers to evacuate in advance.

However, the method of relying on lookouts for observation is prone to danger due to weather affecting visibility, or because the lookouts themselves are in poor spirits or physical condition, resulting in failure to observe the approaching train, or forgetting to remind the construction workers.

Therefore, the existing early warning method for railway construction workers must be improved.

In view of the above problems, the present invention provides an infrared train approaching warning system. The infrared train approaching warning system includes a first infrared receiver, a first infrared transmitter, a second infrared transmitter, a first processor and an alarm.

The first infrared receiver includes a first infrared receiving unit and a second infrared receiving unit. The first infrared transmitter emits a first infrared ray toward the first infrared receiving unit so that the first infrared receiving unit receives the first infrared ray. The second infrared transmitter emits a second infrared ray toward the second infrared receiving unit so that the second infrared receiving unit receives the second infrared ray.

The first processor is communicatively connected to the first infrared receiving unit and the second infrared receiving unit. When the first processor determines that the first infrared receiving unit and the second infrared receiving unit have not received the first infrared ray and the second infrared ray in sequence within a first time, the first processor generates a first alarm signal.

The alarm is connected to the first processor in communication. When the alarm receives the first alarm signal, the alarm generates a first alarm prompt.

The first infrared transmitter and the second infrared transmitter are disposed on the same side of a rail, and the first infrared receiver is disposed on the other side of the rail. That is, the first infrared ray emitted from the first infrared transmitter to the first infrared receiver crosses the rail, and the second infrared ray emitted from the second infrared transmitter to the first infrared receiver also crosses the rail.

When a train passes the rail, the train will sequentially block the first infrared ray and the second infrared ray, so that the first infrared receiving unit and the second infrared receiving unit of the first infrared receiver will be unable to receive the first infrared ray and the second infrared ray sequentially.

Therefore, the first processor can confirm whether the train passes the rail by determining whether the first infrared ray and the second infrared ray are not received in sequence within the first time. If so, the first processing unit will immediately generate the first alarm signal, causing the alarm to generate the first alarm prompt, thereby reminding the rail maintenance personnel who are working to avoid danger.

Since the first infrared receiver and the first and second infrared transmitters can be arranged at a safe distance from the working area of the railroad construction personnel, and the alarm can be arranged in the working area, it is possible to observe whether a train passes by early and remind the railroad construction personnel immediately.

In addition, since the infrared ray is transmitted by the train, the early warning system has two infrared transmitters and uses two infrared rays to confirm whether a train passes by, the possibility of misjudgment can be further avoided.

Furthermore, the first processor can also determine the travel direction of the train according to the blocking sequence of the first infrared ray and the second infrared ray, thereby confirming whether the train is approaching or far away from the working area, thereby avoiding false reminders.

Please refer to FIG. 1 , which is a system block diagram of the novel infrared train approaching early warning system, and the infrared train approaching early warning system includes a first infrared receiver 10 , a first infrared transmitter 21 , a second infrared transmitter 22 , a first processor 30 and an alarm 40 .

The first infrared receiver 10 includes a first infrared receiving unit 11 and a second infrared receiving unit 12. The first infrared transmitter 21 transmits a first infrared ray toward the first infrared receiving unit 11 so that the first infrared receiving unit 11 receives the first infrared ray. The second infrared transmitter 22 transmits a second infrared ray toward the second infrared receiving unit 12 so that the second infrared receiving unit 12 receives the second infrared ray.

The first processor 30 is communicatively connected to the first infrared receiving unit 11 and the second infrared receiving unit 12. When the first processor 30 determines that the first infrared receiving unit 11 and the second infrared receiving unit 12 have not received the first infrared ray and the second infrared ray in sequence within a first time, the first processor 30 generates a first alarm signal and transmits the first alarm signal to the alarm 40.

The alarm 40 is communicatively connected to the first processor 30. When the alarm 40 receives the first alarm signal, the alarm 40 generates a first alarm prompt.

Further, please refer to FIG. 2 , in a first preferred embodiment of the present invention, the first infrared receiver 10 further includes a first communication unit 13. Preferably, in this embodiment, the first processor 30 is disposed in a housing together with the first infrared receiving unit 11, the second infrared receiving unit 12 and the first communication unit 13. Therefore, the first processor 30 is directly electrically connected to the first infrared receiving unit 11, the second infrared receiving unit 12 and the first communication unit 13. In addition, the first processor 30 is connected to the alarm 40 in a wired or wireless manner through the first communication unit 13. When the first processor 30 generates the first alarm signal, the first processor 30 transmits the first alarm signal to the alarm 40 through the first communication unit 13.

For example, referring to FIG3 , the first processor 30, the first infrared receiver 10, the first infrared transmitter 21 and the second infrared transmitter 22 are arranged at a certain distance from the construction area away from the construction workers, and are used to confirm whether a train 81 approaches the construction area. The alarm 40 is arranged near the construction area, and is used to remind the construction workers whether a train is approaching.

The first infrared transmitter 21 and the second infrared transmitter 22 are disposed on the same side of a rail 82, and the first infrared receiver 10 is disposed on the other side of the rail 82. In other words, the first infrared ray emitted from the first infrared transmitter 21 to the first infrared receiver 10 crosses the rail 82, and the second infrared ray emitted from the second infrared transmitter 22 to the first infrared receiver 10 also crosses the rail 82.

When the train 81 passes through the rail 82, the train 81 will sequentially block the first infrared ray and the second infrared ray, so that the first infrared receiving unit 11 and the second infrared receiving unit 12 of the first infrared receiver 10 will be unable to receive the first infrared ray and the second infrared ray in sequence.

Thus, the first processor 30 can determine whether the train 81 passes the rail 82 by determining whether the first infrared ray and the second infrared ray are not received in sequence within the first time. If so, the first processing unit 30 will immediately generate the first alarm signal, causing the alarm 40 to generate the first alarm prompt.

Assuming that the maximum speed of the train 81 is 140 km/h, the first infrared receiver 10 is located 800 meters away from the alarm 40. When the train 81 passes the location of the first infrared receiver 10, it will take at least 20 seconds for the train 81 to reach the construction area. In other words, after receiving the first alarm, the construction workers have at least 20 seconds to react and avoid danger.

Furthermore, the first processor 30 can also determine the travel direction of the train 81 according to the blocking sequence of the first infrared ray and the second infrared ray, thereby confirming whether the train is approaching or far away from the working area, thereby avoiding false reminders.

For example, as shown in FIG2 , when the train 81 passes the location of the first infrared receiver 10 from left to right, the train 81 first blocks the first infrared ray and then blocks the second infrared ray. Therefore, the first processor 30 can determine whether the train passes from left to right or from right to left according to the blocking sequence of the first infrared ray and the second infrared ray.

If the first processor 30 determines that the train 81 passes the setting position of the first infrared receiver 10 from left to right, it means that the train is traveling toward the construction area, and the first processor 30 needs to generate the first alarm signal to remind the construction personnel through the alarm 40. However, if the first processor 30 determines that the train 81 passes the setting position of the first infrared receiver 10 from right to left, it means that the train is traveling far away from the construction area, and the first processor 30 does not need to generate the first alarm signal, thereby avoiding false reminders.

Furthermore, the infrared train approaching early warning system also includes a second infrared receiver 50, a third infrared transmitter 61, a fourth infrared transmitter 62 and a second processor 70.

The second infrared receiver 50 includes a third infrared receiving unit 51 , a fourth infrared receiving unit 52 and a second communication unit 53 .

The third infrared ray transmitter 61 transmits a third infrared ray toward the third infrared ray receiving unit 51 so that the third infrared ray receiving unit 51 receives the third infrared ray. The fourth infrared ray transmitter 62 transmits a fourth infrared ray toward the fourth infrared ray receiving unit 52 so that the fourth infrared ray receiving unit 52 receives the fourth infrared ray.

The second processor 70 is electrically connected to the third infrared receiving unit 51, the fourth infrared receiving unit 52 and the second communication unit 53, and the second processor 70 is connected to the alarm 40 in a wired or wireless manner through the second communication unit 53. When the second processor 70 determines that the third infrared receiving unit 51 and the fourth infrared receiving unit 52 have not received the third infrared ray and the fourth infrared ray in sequence within a second time, the second processor 70 generates a second alarm signal and wirelessly transmits the second alarm signal to the alarm 40 through the second communication unit 53. When the alarm 40 receives the second alarm signal, the alarm 40 generates a second alarm prompt.

Preferably, in this embodiment, the second processor 70 is disposed together with the third infrared receiving unit 51, the fourth infrared receiving unit 52 and the second communication unit 53 in a housing.

By configuring the second infrared receiver 50, the third infrared transmitter 61, the fourth infrared transmitter 62 and the second processor 70, the present invention can observe at both ends of the construction area. No matter which direction the train is traveling from on the rail 82 toward the construction area, the construction workers can be reminded to avoid danger.

In addition, the first alarm signal and the second alarm signal may be different reminder methods, for example, the first alarm signal and the second alarm signal may be different voice contents, and the construction personnel may be directly reminded of the direction of the train 81 by voice, so that the construction personnel may react accurately. Alternatively, the first alarm signal and the second alarm signal may be reminder lights of different colors, and the construction personnel may confirm the direction of the train 81 by observing the color of the reminder lights.

Furthermore, after the first processor 30 generates the first alarm signal, the first processor 30 generates a first alarm cancellation signal after a first delay time, and transmits the first alarm cancellation signal to the alarm 40. When the alarm 40 receives the first alarm cancellation signal, the alarm 40 cancels the first alarm prompt.

After the second processor 70 generates the second alarm signal, the second processor 70 generates a second alarm cancellation signal after a first delay time, and transmits the second alarm cancellation signal to the alarm. When the alarm 40 receives the second alarm cancellation signal, the alarm 40 cancels the second alarm prompt.

In this way, the alarm 40 can be deactivated within the first delay time after the train passes, so as to avoid interfering with the work of the construction personnel. In this embodiment, the first processor 30 and the second processor 70 are respectively a programmable logic controller (PLC).

For example, when the train 81 passes the location where the first infrared receiver 10 is set, the first processor 30 generates the first alarm signal, and when the train 81 passes the location where the first infrared receiver 10 is set for the first delay time, the train 81 has passed the construction area. At this time, the first processor 30 can generate the first alarm cancellation signal to cancel the first alarm.

For example, the first processor 30 delays 40 seconds after generating the first alarm signal to wait for the train 81 to pass through the construction area, and then the first processor 30 generates the first alarm cancellation signal to cancel the first alarm.

In addition, another embodiment of generating the alarm release signal is that after the first processor 30 generates the first alarm signal, the second processor 70 determines that the fourth infrared receiving unit 52 and the third infrared receiving unit 51 have not received the fourth infrared ray and the third infrared ray in sequence within the first time, the second processor 70 generates the first alarm release signal after a second delay time, and transmits the first alarm release signal to the alarm 40 through the second communication unit 53.

In this embodiment, when the train 81 passes the setting position of the first infrared receiver 10, the first processor 30 generates the first alarm signal, and when the train 81 passes the setting position of the second infrared receiver 50, the train 81 will sequentially block the fourth infrared ray and then block the third infrared ray. Therefore, the second processor 70 can judge that the train 81 is far away from the construction area through the blocking sequence of the fourth infrared ray and the third infrared ray, which means that the train has left the construction area, so the second processor 70 generates the first alarm cancellation signal after a second delay time, and transmits the first alarm cancellation signal to the alarm 40 through the second communication unit 53. For example, when the second processor 70 determines that the train 81 leaves the construction area, the second processor 70 delays for 20 seconds and then generates the first alarm cancellation signal to cancel the first alarm.

Specifically, the alarm device 40 includes an alarm communication unit 41 , an alarm processing unit 42 and an alarm unit 43 .

The alarm communication unit 41 is connected to the first communication unit 13 of the first infrared receiver 10 in a wired or wireless manner, and is connected to the second communication unit 53 of the second infrared receiver 50 in a wired or wireless manner.

When the alarm processing unit 42 receives the first alarm signal through the alarm communication unit 41, the alarm processing unit 42 generates the first alarm prompt through the alarm unit 43. When the alarm processing unit 42 receives the second alarm signal through the alarm communication unit 41, the alarm processing unit 42 generates the second alarm prompt through the alarm unit 43.

In addition, when the alarm processing unit 42 determines that a first condition is met, the alarm processing unit 42 sends a first inquiry signal to the first communication unit 13 of the first infrared receiver 10 through the alarm communication unit 41, and determines whether a first reply signal returned by the first infrared receiver 10 is received. When the first communication unit 13 of the first infrared receiver 10 receives the first inquiry signal, the first processor 30 receives the first inquiry signal through the first communication unit 13, generates the first reply signal according to the first inquiry signal, and then returns the first reply signal to the alarm communication unit 41 of the alarm device 40 through the first communication unit 13 for the alarm processing unit 42 to receive.

In addition, when the alarm processing unit 42 determines that the first condition is met, the alarm processing unit 42 also sends a second polling signal to the second infrared receiver 50 through the alarm communication unit 41, and determines whether a second reply signal sent back by the second infrared receiver 50 is received. Similarly, when the second communication unit 53 of the second infrared receiver 50 receives the second polling signal, the second processor 70 receives the second polling signal through the second communication unit 53, generates the second reply signal according to the second polling signal, and then sends the second reply signal back to the alarm communication unit 41 of the alarm device 40 through the second communication unit 53 for the alarm processing unit 42 to receive.

When the alarm processing unit 42 receives the first reply signal through the alarm communication unit 41, the alarm processing unit 42 determines that the first communication unit 13 of the first infrared receiver 10 is connected normally. When the alarm processing unit 42 receives the second reply signal through the alarm communication unit 41, the alarm processing unit 42 determines that the second communication unit 53 of the second infrared receiver 50 is connected normally.

In this way, the alarm 40 can confirm the connection status signal with the first infrared receiver 10 and the second infrared receiver 50 to avoid the system abnormality caused by the failure to receive the first alarm signal or the second alarm signal due to the interruption of the connection, thereby causing danger to the construction personnel.

In this embodiment, the alarm 40 can be a portable electronic device, such as a laptop, a smart phone, a tablet computer, etc., but not limited thereto. The alarm 40 is wirelessly connected to the first infrared receiver 10 or the second infrared receiver 50 through WiFi, Lora, 4G mobile communication, etc.

A first embodiment of determining whether the first condition is met is that the alarm processing unit 42 counts a polling time, and when the polling time times out, the alarm processing unit 42 determines that the first condition is met.

A second embodiment of determining whether the first condition is satisfied is that when the alarm device 40 is powered on, the alarm processing unit 42 determines that the first condition is satisfied.

A third embodiment of determining whether the first condition is met is that the alarm further includes a test switch 44, and the test switch 44 is electrically connected to the alarm processing unit 42. When the alarm processing unit 42 determines that the test switch 44 is activated, the alarm processing unit 42 determines that the first condition is met.

Preferably, the first infrared ray is emitted along a first direction, the second infrared ray is emitted along a second direction, and a first angle between the first direction and the second direction is between 30 degrees and 90 degrees. The third infrared ray is emitted along a third direction, the fourth infrared ray is emitted along a fourth direction, and a second angle between the third direction and the fourth direction is also between 30 degrees and 90 degrees.

Furthermore, the first processor 30 determines a first signal strength of the first infrared ray according to the first infrared ray received by the first infrared receiving unit 11, and determines a second signal strength of the second infrared ray according to the second infrared ray received by the second infrared receiving unit 12. Then, the first processor 30 generates a first infrared life information according to the first signal strength, and generates a second infrared life information according to the second signal strength.

Similarly, the second processor 70 determines a third signal strength of the third infrared ray according to the third infrared ray received by the third infrared receiving unit 51, and determines a fourth signal strength of the fourth infrared ray according to the fourth infrared ray received by the fourth infrared receiving unit 52. Then, the second processor 70 generates a third infrared life information according to the third signal strength, and generates a fourth infrared life information according to the fourth signal strength.

Since the first to fourth signal strengths of the first to fourth infrared signals represent the life states of the first to fourth infrared transmitters 21, 22, 61, 62, respectively. For example, the signal strength of the infrared signal decreases with the use time, therefore, the weaker the signal strength shown, the weaker the life state of the infrared transmitter unit. This reminds the maintenance personnel to perform maintenance and avoids false alarms caused by damage to the infrared transmitter unit.

In addition, the first infrared ray carries a first frequency, the second infrared ray carries a second frequency, the third infrared ray carries a third frequency, and the fourth infrared ray carries a fourth frequency.

When the first processor 30 determines that the first infrared receiving unit 11 receives the first infrared ray or the second infrared receiving unit 12 receives the second infrared ray, the first processor 30 further determines whether an infrared frequency of an infrared ray received by the first infrared receiving unit 11 is the first frequency, and determines whether an infrared frequency of an infrared ray received by the second infrared receiving unit 12 is the second frequency.

When the infrared frequency of the infrared ray received by the first infrared receiving unit 11 is not the first frequency, or when the infrared frequency of the infrared ray received by the second infrared receiving unit 12 is not the second frequency, the first processor 30 generates the signal interference reminder information.

Similarly, when the second processor 70 determines that the third infrared receiving unit 51 receives the third infrared ray or the fourth infrared receiving unit 52 receives the fourth infrared ray, the second processor 70 further determines whether an infrared frequency of an infrared ray received by the third infrared receiving unit 51 is the third frequency, and determines whether an infrared frequency of an infrared ray received by the fourth infrared receiving unit 52 is the fourth frequency.

When the infrared frequency of the infrared ray received by the third infrared receiving unit 51 is not the third frequency, or when the infrared frequency of the infrared ray received by the fourth infrared receiving unit 52 is not the fourth frequency, the second processor 70 generates the signal interference reminder information.

In this way, the first processor 30 and the second processor 70 can determine whether the received infrared rays are the first to fourth infrared rays emitted by the first to fourth infrared emitters 21, 22, 61, 62 according to the infrared frequency, thereby avoiding external interference and improving accuracy.

In addition, the first infrared receiver 10, the first infrared transmitter 21, the second infrared transmitter 22, the second infrared receiver 50, the third infrared transmitter 61 and the fourth infrared transmitter 62 each have a housing for mounting various components. Referring to FIG. 4 , preferably, the first infrared receiver 10 is mounted on the side of the rail 82 by a bracket, and the bracket base is screwed to the ground, thereby, the first infrared receiver 10 is movably mounted on the side of the rail 82 to improve the use efficiency and facilitate installation. In addition, the first infrared receiver 10, the first infrared transmitter 21, the second infrared transmitter 22, the second infrared receiver 50, the third infrared transmitter 61 and the fourth infrared transmitter 62 respectively have a solar panel and a battery for receiving solar energy to charge the battery, and then using the battery to provide power to various components, thereby further improving portability and efficiency of use.

The first processor 30 is disposed in a housing together with the first infrared receiving unit 11, the second infrared receiving unit 12 and the first communication unit 13.

Furthermore, please refer to FIG. 5 , in a second preferred embodiment of the present invention, the first infrared receiver 10 further includes a first communication unit 13.

Preferably, in the present embodiment, the first infrared receiving unit 11, the second infrared receiving unit 12 and the first communication unit 13 are disposed together in a housing, and the first processor 30 is disposed together with the alarm 40 in another housing. Therefore, the first communication unit 13 is directly electrically connected to the first infrared receiving unit 11 and the second infrared receiving unit 12. However, the first infrared receiving unit 11 and the second infrared receiving unit 12 are connected to the first processor 30 in a wired or wireless manner through the first communication unit 13. And the first processor 30 is directly electrically connected to the alarm 40. When the first processor 30 generates the first alarm signal, the first processor 30 directly transmits the first alarm signal to the alarm 40.

The first infrared receiver 10, the first infrared transmitter 21 and the second infrared transmitter 22 are arranged at a certain distance from the construction area of the construction workers to confirm whether a train 81 is approaching the construction area. The first processor 30 and the alarm 40 are arranged in the construction area of the construction workers to remind the construction workers whether a train is approaching.

The installation and operation of the first infrared transmitter 21, the second infrared transmitter 22 and the first infrared receiver 10 at a certain distance from the construction area of the construction workers are the same as those in the first preferred embodiment described above, so they will not be described in detail.

In addition, in the second preferred embodiment, the infrared train approaching warning system further includes a second infrared receiver 50, a third infrared transmitter 61 and a fourth infrared transmitter 62.

The second infrared receiver 50 includes a third infrared receiving unit 51 , a fourth infrared receiving unit 52 and a second communication unit 53 .

The third infrared ray transmitter 61 transmits a third infrared ray toward the third infrared ray receiving unit 51 so that the third infrared ray receiving unit 51 receives the third infrared ray. The fourth infrared ray transmitter 62 transmits a fourth infrared ray toward the fourth infrared ray receiving unit 52 so that the fourth infrared ray receiving unit 52 receives the fourth infrared ray.

The second communication unit 53 is electrically connected to the third infrared receiving unit 51 and the fourth infrared receiving unit 52 , and the third infrared receiving unit 51 and the fourth infrared receiving unit 52 are connected to the first processor 30 via the second communication unit 53 in a wired or wireless manner.

When the first processor 30 determines that the third infrared receiving unit 51 and the fourth infrared receiving unit 52 have not received the third infrared ray and the fourth infrared ray in sequence within a second time, the first processor 30 generates a second alarm signal. When the alarm receives the second alarm signal, the first processor 30 generates a second alarm prompt and transmits the second alarm signal to the alarm 40. When the alarm 40 receives the second alarm signal, the alarm 40 generates a second alarm prompt.

Preferably, in this embodiment, the third infrared receiving unit 51, the fourth infrared receiving unit 52 and the second communication unit 53 are disposed together in a housing.

Furthermore, after the first processor 30 generates the first alarm signal, the first processor 30 generates a first alarm cancellation signal after a first delay time, and transmits the first alarm cancellation signal to the alarm 40. When the alarm 40 receives the first alarm cancellation signal, the alarm 40 cancels the first alarm prompt.

After the first processor 30 generates the second alarm signal, the first processor 30 generates a second alarm cancellation signal after a first delay time, and transmits the second alarm cancellation signal to the alarm. When the alarm 40 receives the second alarm cancellation signal, the alarm 40 cancels the second alarm prompt.

In addition, another embodiment of generating the alarm release signal is that after the first processor 30 generates the first alarm signal, the first processor 30 determines that the fourth infrared receiving unit 52 and the third infrared receiving unit 51 have not received the fourth infrared ray and the third infrared ray in sequence within the first time, and then the first processor 30 generates the first alarm release signal after a second delay time, and transmits the first alarm release signal to the alarm 40 through the second communication unit 53.
