Example 1

As shown in Figures 1 and 2, the utility model provides an audible and visual alarm system suitable for passengers entering and exiting the escalator, including: a detection unit 2, which is arranged at the entrance and exit of the escalator 1 and is used to detect the entry or exit of passengers. Escalator 1; the acoustic alarm unit 3 is set at the entrance and exit of the escalator 1. When the detection unit 2 detects a passenger, the acoustic alarm unit 3 sends an alarm sound; the light prompt unit 4 is set at the entrance and exit of the escalator 1. When the detection unit 2 detects a passenger, the light prompt unit 4 projects a light prompt area at the entrance and exit of the escalator 1 .

Specifically, two detection units 2 are respectively installed at the entrance and exit of the escalator 1 to detect whether there are passengers entering or leaving the escalator. The detection units 2 may be photoelectric sensor detection, weight detection, etc.

There are two acoustic alarm units 3 and two light prompt units 4 respectively, and they are also respectively installed at the entrance and exit of the escalator 1 .

The acoustic alarm unit 3 can be a speaker, etc., with recording and playback functions. For example, the security or management personnel pre-enter the language "Please pay attention to your steps and travel safely". When the detection unit 2 detects a passenger, the acoustic alarm unit 3 plays the alarm prompt sound " Please watch your step and travel safely” to attract the attention of passengers.

The light prompt unit 4 can be a high-brightness projection lamp, projecting a bright light prompt area at the entrance and exit of the escalator 1; or the light prompt unit 4 can be a different-color projection lamp, projecting a bright light prompt area at the entrance and exit of the escalator 1. A light prompt area of conspicuous colors such as different colors (such as red, yellow); or the light prompt unit 4 can be a flashing projection lamp, projecting a periodic flashing light prompt area at the entrance and exit of the escalator 1, etc. When passengers are focused on the mobile phone screen, the light prompt area can still be observed by passengers' peripheral vision due to the significant visual sensory contrast, so it can still have the effect of attracting passengers' attention.

Example 2

As shown in Figures 1 and 2, it also includes a controller 5. The controller 5 obtains the detection signal of the detection unit 2 and outputs a control signal to the acoustic alarm unit 3 and the light prompt unit 4. The controller 5 is installed in the drive control cabinet.

Specifically, the controller 5 can be a PLC programmable logic controller, which is connected to the detection unit 2. When a passenger is detected near the entrance or exit, a signal is transmitted to the controller 5 as a judgment that someone has entered or exited the escalator. When the controller 5 determines that someone is entering the escalator, it outputs a control signal to the acoustic alarm unit 3 and light prompt unit 4 at the entrance of the escalator; when the controller 5 determines that someone is leaving the escalator, it outputs a control signal to the acoustic alarm unit at the exit of the escalator. 3 and light prompt unit 4. The drive control cabinet is arranged in the lower space of the escalator 1. The controller 5 is installed in the drive control cabinet and can be connected to the detection unit 2, the acoustic alarm unit 3 and the light prompt unit 4 through wired or wireless means.

Example 3

As shown in Figures 1 and 2, the detection unit 2 includes a photoelectric sensor. The acoustic alarm unit 3 includes a speaker. The light prompt unit 4 includes a light emitting module. The light prompt area is located at the intersection line between the escalator 1 comb plate and the steps. The light prompt area is the highlight area illuminated by the light-emitting module. At the entrance of the escalator 1, the detection unit 2 is located on the upstream side of the acoustic alarm unit 3 and the light prompt unit 4. At the exit of the escalator 1, the detection unit 2 is located on the upstream side of the acoustic alarm unit 3 and the light prompt unit 4.

Specifically, photoelectric sensors and speakers are existing technologies and can be purchased through online or offline channels, so no further details will be given. The light-emitting module mainly includes a projection light source. The light-emitting module is installed at the entrance and exit of the escalator 1. The light can shine on the intersection line of the comb plate and the steps.

At the entrance and entrance of the escalator 1, along the escalator running direction, the detection unit 2 is located on the upstream side. Passengers are first detected by the photoelectric sensor, and then the speaker sounds and the light-emitting module projects a light prompt area.

The working method and principle of this system:

The photoelectric sensor is installed near the escalator entrance and exit. When it detects someone near the entrance and exit, the signal is transmitted to the controller 5 as a judgment that someone is entering or exiting the escalator.

The speaker is installed near the escalator entrance and exit. When the controller 5 receives the photoelectric sensor signal, the controller 5 outputs the signal to the speaker, and the speaker plays the voice "Please pay attention to your steps and travel safely."

The light-emitting module is installed at the entrance and exit of the escalator 1. When the controller 5 receives the photoelectric sensor signal, the controller 5 outputs a signal to the light-emitting module, and the light can be illuminated on the intersection line between the comb plate and the steps.

Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it. Although the present utility model has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that : It is still possible to modify the technical solutions recorded in the foregoing embodiments, or to equivalently replace some or all of the technical features; and these modifications or substitutions do not deviate from the essence of the corresponding technical solutions from the embodiments of the present invention. Scope of technical solutions.
