Problems solved by technology

The second is to use sensors to monitor the operating status of the elevator door, but this method has requirements for the installation of the equipment. The equipment can only be installed in the plywood of the elevator door. At this time, the power supply of the equipment becomes a problem. The plywood in the elevator door It is difficult for the equipment to be connected to the power system of the elevator

Embodiment 1

[0063] Such as image 3 , a kind of ultra-low power consumption fault detection method, described method relates to the sensor that is arranged in elevator door, controller, battery, and this battery is 2 button batteries, and described battery supplies power for sensor, controller, and described sensor is built-in There is a FIFO memory, and the working mode of the sensor includes a FIFO mode for writing data into the FIFO memory and a Bypass mode for not writing data into the FIFO memory;

[0064] It needs to be said that the purpose is: the method of the present invention is especially suitable for the detection of the door opening and closing fault of the elevator door, but it does not mean that it is only suitable for the detection of the door opening and closing of the elevator door. For example, in some scenes, it is necessary to continuously observe and judge the temperature and pressure. It is also applicable in scenarios. For example, in electric vehicles, for the te...

Embodiment 2

[0103] refer to Figure 4 , an ultra-low power consumption elevator door opening / closing fault detection device for implementing the method described in embodiment 1, comprising a sensor 1 for detecting acceleration installed in the elevator door, a controller 2, and a battery 3, the The battery 3 supplies power to the sensor 1 and the controller 2. The sensor 1 has a built-in FIFO memory 4. The working mode of the sensor 1 includes the FIFO mode of writing data into the FIFO memory 4 and not writing data into the FIFO memory 4. Bypass mode;

[0104] The sensor 1 is provided with the following modules:

[0105] The first overflow interrupt value control module 11: used to set the first overflow interrupt value, and generate a signal to wake up the controller 2 when the data in the FIFO memory 4 reaches the first overflow interrupt value;

[0106] The second overflow interrupt value control module 12: used to set the second overflow interrupt value according to the instructio...

Abstract

The invention belongs to the field of Internet of Things, and discloses an ultra-low power consumption fault detection method. The method comprises the steps that 1 a sensor enters an FIFO (First In First Out) mode, and a first overflow interrupt value is set; 2 the sensor wakes up a controller; 3 the controller analyzes the data of the FIFO memory to obtain an analysis result; 4 the controller sets the sensor to be in a Bypass mode, and the controller enters a sleep mode; 5 the controller enters a sleep mode; 6 the sensor wakes up the controller to enable the controller to be in a working mode; and 7 the controller analyzes the data collected by the FIFO memory in the step 6. The method is suitable for most situations of fault detection which is inconvenient for mains supply access. Meanwhile, the invention further discloses an ultra-low power consumption elevator door opening / closing fault detection device which is based on the method and particularly suitable for elevator door faults.

Description
