Description
Technical field
The utility model relates to be exclusively used in the blasting method or equipment that delay is ignited, espespecially a kind of charging of electric detonator
With initiation net system.
Background technique
Nearly ten years, electric detonator technology in China's achieves rapid progress and development, and electric detonator is also gradually applied to quick-fried
Broken market, but since the networking mode of electric detonator and its initiating ability and anti-interference ability have very big relationship.Therefore exist
There is certain limitation in terms of application places.
Summary of the invention
In view of the shortcomings of the prior art, the purpose of this utility model is to provide a kind of chargings of electric detonator and detonation net
Network system.Aim to solve the problem that electronic detonator initiating network interferences and detonation apart from the problem of, to solve in mine and tunnel piercing
Interference effect problem of the electromagnetic signal to electric detonator.
The technical scheme adopted by the utility model to solve the technical problem is as follows: providing a kind of charging of electric detonator and rising
Quick-fried network system, including charging initiation control device, blasting network and electric detonator, it is characterised in that: the electric detonator system fills
Power failure detonation formula electric detonator after electricity, is concatenated composition blasting network, which passes through bus and charging initiation control device
Connection, the charging initiation control device converts battery energy into the direct current output of 20 ± 2ma using constant current boost device, with perseverance
Stream mode is charged by electric detonator of the blasting network into network ignites.
The pressure voltage of shot firing cable used in blasting network (electric wire or cable) is not less than 2000VDC, line, and resistance is not more than
0.5 ohm/meter, shot firing cable total length is not more than 50KM, and bus line resistance is inversely proportional with total length.
The initiation control device that charges is delayed using the wide warm area microprocessor of built-in high-precision rc oscillator, has precision height,
It is influenced by factors such as environment temperatures small.Within the extension time up to 9000 milliseconds, various sections of other errors are all setting value
± 1ms.
The network connection, charging and signal transmission of the utility model use class electric current loop technique, have stronger anti-interference
Ability, while fault-toleranr technique is used, increase the reliability of signal transmission.Therefore, in the relatively other electricity in strong electromagnetic place
Sub- detonator agrees have greater advantage.
The utility model is simple and convenient with network connection, initiation control device is easy to operate easy to learn, to bursting work personnel
It is of less demanding, it is suitable for China's bursting work status.
The beneficial effects of the utility model are: delay precision is high, consistency is good, application method is simple, reliability and safety
Property it is high, cheap, can be the domestic generally accepted electronic detonator blasting mode of users, to substitute current detonator
The detonation mode of detonator, electric cap, be applicable in except the contour temperature high-voltage field of oil well and containing each in addition to explosive gas (dust)
Kind explosion demand.
Detailed description of the invention
The utility model will be further described with reference to the accompanying drawing.
Fig. 1 is the system structure diagram of the utility model.
Fig. 2 is the electrical block diagram of the utility model.
In figure: 1 being initiation control device, 11 be high voltage step-up constant-current source, 12 be electronic switch, 13 be fictitious load, 2 be explosion
Bus, 3 are electric cap.
Specific embodiment
Referring to attached drawing, a kind of charging of electric detonator of the utility model and initiation net system, including charging initiation control
Device 1, blasting network and electric detonator 3, it is characterised in that: power failure detonation formula electric detonator after 3 system of the electric detonator charging, warp
It is composed in series blasting network, which is connect by bus 2 with charging initiation control device 1, the charging initiation control device 1
The direct current output of 20 ± 2ma is converted battery energy into using constant current boost device, and blasting network is passed through to net with current constant mode
Electric detonator in network, which charges, to be ignited.
In the embodiments of the present invention:
Shot firing cable 2(electric wire or cable used in blasting network) pressure voltage be not less than 2000VDC, line, resistance is not more than
0.5 ohm/meter, shot firing cable total length is not more than 50KM, and bus line resistance is inversely proportional with total length.
The initiation control device 1 that charges is delayed using the wide warm area microprocessor of built-in high-precision rc oscillator, has precision height,
It is influenced by factors such as environment temperatures small.Within the extension time up to 9000 milliseconds, various sections of other errors are all setting value
± 1ms.
The blasting network, charging and signal transmission use class electric current loop technique, have strong anti-interference ability, simultaneously
Using fault-toleranr technique, the reliability of signal transmission is increased.Therefore, in the relatively other electric detonators in strong electromagnetic place, agree
There is greater advantage.
