Method for receiving electronic detonator control chip signals and detecting current of electronic detonator

Abstract

The invention discloses a method for receiving electronic detonator control chip signals and detecting current of an electronic detonator. The electronic detonator, a sampling resistor, an operational amplifier, an ADC, an MCU and an upper computer are mainly included. On the basis of the principle of the method, a current signal of the electronic detonator is converted into a voltage signal and then the voltage signal is sent to the ADC to be processed. According to the specific achieving steps, the current of the electronic detonator is changed into the voltage signal through the sampling resistor, then the voltage signal becomes a digital quantity through the ADC to be transmitted to the MCU, the MCU analyzes the current value and communication data, the state of the detonator is judged, and corresponding operation is conducted. Meanwhile, the MCU transmits the digital signal to the upper computer, and the state information of the electronic detonator is displayed on the upper computer through the processed digital signal. According to the design, communication and signal collection are conducted at the same through an access, design is simple, achieving is easy, and the anti-jamming capability is high. By means of the method, the current of the electronic detonator can be monitored in the whole life cycle of the electronic detonator, and communication with the upper computer is kept.

Description

[0001] 1. Technical field: [0002] The invention relates to the technical field of pyrotechnics detection, in particular to a method for receiving a signal from an electronic detonator control chip and detecting its current. [0003] 2. Background technology: [0004] Electronic detonators, also known as digital electronic detonators, digital detonators or industrial digital electronic detonators, are electric detonators that use electronic control modules to control the detonation process. Compared with ordinary detonators, it is a new type of electric detonator that can be set arbitrarily and accurately achieve the delayed firing time. Its essence lies in the control of a microelectronic chip, which replaces the delay charge and electric ignition element in the ordinary detonator, which not only greatly improves the delay accuracy, but also controls the power supply to the ignition head, thereby reducing the energy caused by the ignition head to the greatest extent. errors ...
