Description
Technical Field
The invention relates to the technical field of civil blasting equipment performance detection, in particular to a detonator delay time testing system and a testing method.
Background
With the continuous maturation and development of electronic detonator technology, it is widely accepted in the global blasting community. The electronic detonator adopts an electronic control module to replace delay powder of the traditional electronic detonator, thereby realizing the precise control of delay time and achieving precise blasting. The delay time is an important index for representing the performance of the electronic detonator. The delay time of the electronic detonator refers to the time interval between the detonation controller sending the explosion signal to the explosion of the electronic detonator.
The conventional delay time detection device can be used for detecting the delay time of the electric detonator and the detonating tube detonator or the detonation velocity of the detonating tube. When the electric detonator is detected, the electric detonator is detonated by the detection equipment, and the detection equipment generates a target trigger starting signal. When the delay time of the detonator and the detonation velocity of the detonating tube are detected, the delay detection equipment collects a detonator detonation signal or an optical signal generated when the powder is filled in the detonating tube and the detonating tube is detonated as a target trigger signal to start the detection of the delay time. Because the electronic detonator depends on the instruction to detonate the electronic detonator, the traditional delay second detection equipment cannot be directly applied to delay measurement of the electronic detonator.
The existing electronic detonator delay time measurement generally adopts two methods:
The method comprises the following steps: delay detection equipment special for electronic detonator: for example, "CN201748868U electronic detonator sampling inspection device" and "CN201476721U a detonator delay time measuring device using photoelectric technology" refer to delay time detection equipment, in which the detection of detonation and delay seconds of electronic detonator is realized in the same equipment, the equipment outputs a timing start signal for starting delay detection while detonating electronic detonator instruction, and after collecting explosion signal, the timer is notified to work, so as to realize the detection of delay time, the scheme has the following disadvantages:
1. the delay detection equipment needs to detonate the electronic detonator, a series of instructions need to be sent to the electronic detonator, and the electronic detonator instruction systems of all factories are different, so that the detection equipment of all factories are not mutually compatible, only the detection requirements of the own electronic detonator can be met, and the electronic detonators of other factories cannot be detected;
2. The electronic detonator and delay detection equipment are self-developed by various manufacturers, and the manufacturers exist to ensure that the delay time of the self-family electronic detonator is qualified, for example, the unqualified data on the detection equipment is processed in the background, the calibration mode of the electronic detonator is processed in the special mode, and the authority of the detection result is reduced;
3. When the electronic detonator is applied, the delay time is calibrated, set and controlled by the detonator, the delay precision of the detonator not only depends on the detonator but also depends on the correlation of the detonator, only the precision of the electronic detonator is inspected, and the actual application precision of the electronic detonator and the detonator when being matched is difficult to judge;
The second method is as follows: the delay time detection adopts traditional delay detection equipment, two power generation electronic detonators are used during detection, one power generation electronic detonator is set to be instant power generation, an optical signal generated by explosion is used as a target signal, and the two target signals are explosion signals of a second power generation detonator;
1. the cost of detection is relatively high by using two detonators;
2. The target signal is an explosion signal of an electronic detonator, and the explosion signal has deviation and can influence the deviation of the delay time detected by time;
3. Because the primary target signal is not standard, when the acquisition delay time is not qualified, whether the primary target signal is caused to be unqualified or whether the primary target product is unqualified is difficult to judge.

The initiator 100 includes a transmission interface 110 and a detonator interface 120, the transmission interface 110 is connected with the light emitting tube 600, and the initiator 100 sets a delay time of the electronic detonator 400 so that the electronic detonator 400 is in a state to be excited. The transmission interface 110 may be a cascade interface. And, the transmission interface 110 may further include a communication interface.
To accommodate large-scale detonations, a cascading interface is typically required between the initiators 100 for data interaction between the devices. In addition, the transmission interface 110 of the initiator 100 may also be provided with a communication interface for communicating with a computer. The initiator 100 is further provided with a detonator interface in communication with the electronic detonator 400, thereby implementing initiation control of the electronic detonator 400.
The cascade interface and the communication interface are connected with an external luminous tube 600, and when the electronic detonator 400 is detonated, the detonator 100 controls the luminous tube 600 to generate an optical signal. A light receiving sensor 700 is disposed opposite to the light emitting tube 600, and the light receiving sensor 700 receives the light wave signal and further transmits the light wave signal to the delay time detector 300, and starts the delay time.
