The invention provides a detonation device safety detection circuit and detonation device safety detection equipment. The circuit includes: a first adjustable resistance, a first controllable switch, a second controllable switch, a standard resistance and a voltage measurement circuit, wherein the first adjustable resistance One end of an adjustable resistor is connected to the positive pole of the external constant voltage power supply, and the other end is connected to the first end of the first controllable switch and the second controllable switch respectively; the second end of the first controllable switch is connected to one end of the standard resistor connection, the third end is connected to one end of the voltage measurement circuit; the second end of the second controllable switch is connected to one end of the resistance to be measured in the detonating device, and the third end is connected to one end of the voltage measurement circuit; the other end of the standard resistance is respectively It is connected to the other end of the resistance to be measured and the other end of the voltage measurement circuit, and then connected to the negative pole of the external constant voltage power supply. Therefore, the measurement requirements of the actual resistance value of the internal resistance wire of the detonator are met, and the measurement safety is ensured. The circuit has the characteristics of simple structure and low cost.
Description
technical field [0001] The invention relates to the technical field of explosives, in particular to a detonating device safety detection circuit and detonating device safety detection equipment. Background technique [0002] Explosives are widely used in more and more fields because of their advantages of low cost, saving manpower, and speeding up engineering construction. Explosives can be used in the military as explosive charges for ammunition such as artillery shells, aerial bombs, missiles, mines, torpedoes, and grenades, as well as detonators for nuclear bombs and military blasting. It is widely used in mining, road construction, water conservancy construction, engineering blasting, metal processing, etc. in industry, and it is also widely used in scientific and technological fields such as seismic exploration. [0003] Among them, the working principle of the conventional explosive device is to apply a voltage on the detonation power line, and the voltage passes thro...
