A shutdown alarm device for an escalator, the embodiment of which is shown in fig. 1:
a depth distance sensor is respectively arranged on the roof above the escalator and opposite to the position of the entrance of the escalator and the position of the exit of the escalator. The two depth sensors 1 together form a binocular depth sensor 1, and the depth from the entrance and the exit of the escalator to the roof after shutdown can be detected by the binocular depth sensor 1 so as to obtain depth data.
Under the waiting areas at the entrance and exit of the escalator, a step pressure sensor 4 is installed, respectively. The pressure of the inlet and the outlet of the escalator after shutdown can be detected by the step pressure sensor 4 so as to obtain the pressure value of the inlet and the outlet.
Under handrails 6 on both sides of the entrance and exit of the escalator, one handrail pressure sensor 3 is installed, respectively. The pressure of the handrail 6 at the inlet and the outlet of the escalator after shutdown can be detected by the handrail pressure sensor 3 so as to obtain the pressure value of the handrail 6 at the inlet and the outlet.
The depth at the entrance and exit, the pressure value of the waiting zone 7 before the steps and the pressure value on the handrail 6 should be constant when the escalator is in a stopped state. Therefore, by regularly acquiring the depth at the entrance and the exit, the pressure value of the waiting area 7, and the pressure value on the handrail 6, it is possible to determine whether a person walks on the escalator by comparing the acquired values.
The data transmission unit collects depth data, pressure values of the waiting area 7 and pressure values on the handrail 6 transferred from the binocular depth sensor 1, the step pressure sensor 4 and the handrail pressure sensor 3 by means of wired or wireless (e.g. radio frequency, bluetooth, zigbee). And the timing acquisition is realized, and the acquisition mode can be completed by setting a clock chip. The data transmission unit transmits the information to the data processing unit, and the data processing unit is a singlechip.
When collecting the depth data, the pressure value of the waiting area 7 and the pressure value on the handrail 6, the data values collected in the first two time periods are respectively subjected to average value processing to obtain an average value of the depth data in the first two time periods, the pressure value of the waiting area 7 and the average value of the pressure value of the handrail 6. Meanwhile, comparing the depth data obtained in the normal acquisition period with the average value of the depth data to obtain a depth difference value; comparing the pressure value of the waiting area 7 obtained in the normal acquisition period with the average value of the pressure values of the waiting area 7 to obtain a pressure value difference value of the waiting area 7; and comparing the pressure value of the handrail 6 obtained in the normal acquisition period with the average value of the pressure values of the handrail 6 to obtain a pressure value difference value of the handrail 6.
A predetermined depth difference threshold value, a waiting area 7 pressure difference threshold value and an armrest 6 pressure difference threshold value are also stored in the data processing unit. When one or more of the depth difference value obtained by detection and analysis in the period, the pressure difference value of the waiting area 7 and the pressure difference value of the handrail 6 exceeds a preset threshold value, an alarm is sent out through the alarm display unit 2.
In this embodiment, the alarm display unit 2 includes an alarm transmitting alarm information in the form of sound waves, a display transmitting alarm information in the form of light waves, and a fixing member for fixing the alarm and the display.
The fixing piece comprises a locating plate and a mounting plate, wherein the locating plate and the mounting plate are respectively arranged on the outer walls of an inlet and an outlet of the escalator, and the mounting plate and the locating plate are integrally formed. The locating plate is arranged on the escalator through bolts. The alarm is actually a buzzer and is arranged on two sides of the mounting plate. Three alarm display lamps with different colors are arranged on the display, and correspond to the depth sensor 1, the pressure sensor of the waiting area 7 and the pressure sensor on the handrail 6 respectively.
The depth of the entrance and the exit of the escalator 5, the pressure value of the waiting area 7 and the pressure value of the handrail 6 are respectively detected through the binocular depth sensor 1, the stair pressure sensor 4 and the handrail pressure sensor 3, and the timely alarm of people after walking on the escalator 5 is completed through monitoring and comparing through the data processing unit, so that the problem that the traditional escalator in a stop state still walks pedestrians and the escalator cannot set up a stop alarm device to give an alarm and give an alarm is solved.
The present utility model is not limited to the above embodiments, but is capable of modification and variation in detail, and other modifications and variations can be made by those skilled in the art without departing from the scope of the present utility model.
