The explosive is a substance which can be violently burnt (i.e. exploded) in a very short time, and can be exploded by self energy under the action of certain external energy. Generally, the chemical and physical properties of the explosive are stable, but no matter whether the environment is sealed or not, the amount of the explosive is large, even under the condition of zero oxygen supply outside, the explosive can do stable detonation work to the outside as long as strong energy (provided by the initiating explosive) is used for excitation. When explosive explodes, a large amount of heat energy can be released, high-temperature and high-pressure gas is generated, and the effects of damaging, throwing, compressing and the like on surrounding substances are achieved. Due to the characteristics of the explosive, once the explosive is abnormally detonated or flows into the society, the safety and stability of the society are seriously damaged, and the safety of the state and the property of people is greatly threatened. Therefore, monitoring of the blast items is essential and important.

Explosives are generally classified into two broad categories according to the form of packaging: packing explosive and bulk explosive, wherein the packing explosive is common and comprises roll packing, bagging and box packing of various specifications. Bulk explosives refer to explosives that are charged entirely by on-site loading equipment. The current bulk explosives are classified as bulk emulsion explosives and bulk porous granular ammonium nitrate fuel oil explosives or a combination of the two. It has no fixed packaging size and packaging number per se.

The digital electronic detonator system generally comprises three parts, namely an initiator, a programmer and a digital electronic detonator, wherein the digital electronic detonator needs to be connected with the special initiator for matching use, and the initiator sends an ignition instruction to detonate. In addition, in practical application, the operation of the initiator as a trigger device of the detonator must be carried out by designated staff, so that signals transmitted and received by the initiator must be accurate, the signal is prevented from being distorted in each link of generation, conversion and transmission of the signal in the transmission process due to the environment and the existence of interference, even under quite a plurality of conditions, the distortion is serious, so that the signal and information carried by the signal are deeply buried in noise, the information contained in the signal cannot be stored due to the distortion, the information before the distortion cannot be stored in the initiator in time, the information is lost, the detonation of the electronic detonator is wrong or cannot be carried out smoothly, and the personal and property safety is even damaged.
