The invention discloses an intelligent elevator door control alarm device based on stable power sources. The intelligent elevator door control alarm device comprises a power source module, a charge amplifier, a wrong floor detection module, a wireless communication module, a processing module, a lifting driving circuit, a lifting motor, elevator buttons and detection pedals, wherein the elevator buttons and the detection pedals are arranged in front of elevator doors of all floors. The wrong floor detection module comprises a door opening detection module, an alarm module, a first infrared light emitting diode, a second infrared light emitting diode, a first infrared receiver and a second infrared receiver, wherein the first infrared light emitting diode and the second infrared light emitting diode are arranged in an elevator shaft and right face an elevator opening, the first infrared receiver is arranged on the upper portion of the back side of an elevator car, and the second infrared receiver is arranged on the lower portion of the back side of the elevator car. The power source module comprises a CC2530 chip, an LTC4414 chip, the main power source, the backup power source, a first resistor, a second resistor, a third resistor, a fourth resistor, a fifth resistor, a first P-channel field effect tube, a second P-channel field effect tube, a third P-channel field effect tube, a fourth P-channel field effect tube, a first light emitting diode and a first capacitor. According to the intelligent elevator door control alarm device, the using efficiency and safety of the elevator are improved on the basis of the stable power sources.
