specific Embodiment approach 1
[0030] Specific implementation mode one: combine figure 1 Understanding this embodiment, a heart rate recognition device described in this embodiment is characterized in that the heart rate recognition device includes an acquisition chip A, a single-chip microcomputer B, a radio frequency chip C, a programming selection interface circuit D, a reset circuit E, and a crystal oscillator circuit F, programming selection interface circuit G, crystal oscillator circuit H and high-pass circuit I;
[0031] Acquisition chip A is BMD101 acquisition chip, single-chip microcomputer B is STM32F103RBT6 single-chip microcomputer, wireless radio frequency chip C is nRF24L01 wireless radio frequency chip;
[0032] Wherein, the two input terminals of the high-pass circuit 1 are respectively connected with the sensor 1 and the sensor 2 for collecting the electrocardiographic signal of the human body, the sensor 1 is connected with one end of the resistor R2 of the high-pass circuit 1, and the se...
specific Embodiment approach 2
[0041] Specific embodiment 2: The difference between this embodiment and specific embodiment 1 is that the heart rate recognition device also includes a peripheral circuit J, which is connected to the corresponding port of the nRF24L01 wireless radio frequency chip, and is used to change the transmission power of the wireless signal .
[0042] Other steps are the same as in the first embodiment.
specific Embodiment approach 3
[0043] Specific implementation mode three: the difference between this implementation mode and specific implementation mode one or two is that: the method for identifying personnel who fires underground coal mines based on the heart rate identification device includes the following steps:
[0044] Step 1. The mine ground monitoring center located on the well collects the heart rate information of the blasting personnel through the heart rate acquisition chip, and stores it in the main computer of the mine ground monitoring center;
[0045] Step 2. Before performing the blasting task, send the heart rate information of the blasting personnel to the FB200LS mine chain detonator through the main computer server of the mine ground monitoring center on the well, and set the blasting location so that the blasting location and the blasting personnel uniquely correspond;
[0046] Step 3. When performing the blasting task underground, the blasting personnel use the heart rate recognitio...
