[0040] The voice playing module is an MP3 voice playing module.

[0041] Embodiment:

[0042] In this example, the elevator safety guardrail device is composed of a φ25 PVC pipe and components, 3 Oxford yellow cloths, a WiFi control circuit board, a human body sensor, an MP3 voice player, and a lithium battery charging module.

[0043] The elevator safety guardrail frame structure is specifically composed of 3 fences and PVC pipes and connecting pieces. Each fence is composed of 2 φ25 long 500mm pipes and 2 φ25 long 745mm pipes, which are connected by PVC elbows to form a rectangular fence. An Oxford cloth with a safety warning slogan with a length of 780mm and a width of 530mm is embedded in the fence frame. The 3 fences are connected by rotating clamps, and the left and right two fences can be folded into a single face shape.

[0044] The WiFi control board mainly has an ESP-07S single-chip module, which has a core processor ESP8266. The module integrates a super-low-power 32-bit microcontroller in a small size package, with a 16-bit reduced mode, a main frequency supporting 80MHz and 160MHz, supporting RTOS, and integrating Wi-Fi MAC / BB / RF / PA / LNA. The ESP-07S Wi-Fi module supports standard IEEE802.11b / g / n protocols and complete TCP / IP protocol stacks. The module can be used to add networking functions to existing devices or build independent network controllers. ESP8266 is a high-performance wireless SoC that provides the maximum implementation of Wi-Fi system functions at the lowest cost.

[0045] The device can realize the functions of controlling the LED light group, connecting the human body sensor to control the MP3 player, and using WiFi to realize networking management, etc. by using the ESP-07 module.

[0046] The elevator safety guardrail device has a dynamic LED display function, and φ5 red LED lamps are distributed around the guardrail, 102 red LEDs are distributed in the upper and lower PVC pipes, and 52 red LEDs are distributed in the left and right PVC pipes. The LED dynamic display is controlled by the GPIO3 port of the WiFi control board. Through program design, the LED lamp group can be turned on every 1 second and turned off every 1 second, and the cycle is repeated regularly. In this way, the LED lamp has a dynamic display effect.

[0047] The LED display lamp group is divided into 20 groups, each group has 8 LEDs, and each group of LED lamps is powered by DC12V. The driving tube uses PNP triode 8550, and the base of S triode 8550 is connected to the GPIO3 port of the WiFi control board, which controls the conduction and cutoff of the triode.

[0048] The human body sensing module is mainly composed of digital pyroelectric infrared sensor L916, resistor and light emitting diode. When a human body enters the detection area, there is a difference between the body temperature and the environmental temperature, which produces ΔT, and there is a signal output. If the human body does not move after entering the detection area, the temperature does not change, and the sensor does not output. Based on this principle, the activity of human body or animal is detected.

[0049] The MP3 voice module has a built-in 16MB storage space, without the need for external SD card. If one sound effect is calculated in seconds, 16M of memory can store multiple sound effects. The storage method is as simple as using a USB, and the sound effects in the module can be updated at any time. The PH2.0 interface is used, which reduces the trouble of wiring; it supports MP3 and WAV audio formats, and can play specified, loop, single loop, next or previous, etc. The MP3 module has a built-in speaker interface, which can directly drive a passive small speaker. Before use, download the audio MP2 to the board through the built-in USB port using the download software.

[0050] Since the LED lamp group is powered by DC12V, the power supply is composed of 3 strings of 18650 lithium batteries and a charge and discharge board. In this device, 3 strings of 11.1V 18650 lithium batteries are used as power supply, and the 3 strings of lithium batteries are connected with the charge and discharge modules B1, B2, B+, B- respectively. The input of the charging seat and the input of the LED group power supply are connected to P+ and P- respectively.

[0051] The WiFi control board, human body sensing module and MP3 player module power supply use DC3.3V, and the 12V power supply needs to be converted to 3.3V before use. The power conversion circuit used is composed of ASM117-3.3 three-terminal voltage regulator chip (SOT-223) and power button switch filter capacitor. ASM117-3.3 is a surface-mounted package, and the output voltage is 3.3V forward low dropout regulator.
