Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model.
The specific embodiment
Embodiment of the present utility model: the fixing device that detonates of defer time electric detonator networking, the communication interface of the special-purpose initiator 1 below 64 is connected with the communication interface of master controller 3 by the positive and negative back in parallel respectively of communication by twisted-pair feeder 2, makes them form an explosion net by the CAN bus; On initiator 1, also install detonator detection module and signal feedback module, and on master controller 3, possess human-machine interactive information module and signal checking module.
Principle of the present utility model is: the initiator more than is in parallel with a master controller by the CAN bussing technique, form an explosion net, sending broadcast singal by CAN bussing technique master controller to initiator comes the detonator of control connection on initiator to detect and detonates, after initiator is received the broadcast singal of master controller transmission, to return to feedback signal of master controller, the error-checking code of trailing communication CRC after this feedback signal is come the accuracy of checking data communication; Feedback signal comprises supply voltage, output voltage, the output current of initiator and detects the address of detonator and communication data such as defer time; Master controller is after initiator sends broadcast singal, and initiator interrupts existing operating process and the executive communication interrupt service routine at once.
In use, electric detonator 8 is connected in parallel on the initiator 1, as the one side of technical solutions of the utility model, the initiation control flow process of 1 pair of electric detonator 8 of above-mentioned initiator is carried out according to following steps:
The first step, initiator 1 is waited for the command information of master controller 3.
In second step, if initiator 1 receives that the detection that master controller 3 sends over powers on when instructing, the control module of initiator 1 inside is opened the detection voltage path, detects the operation that powers on for electric detonator 8, carries out the operation of the 3rd step again.Otherwise the execution first step.If when electric detonator 8 had short circuit, then initiator 1 cut out the voltage output channel and carried out for the 7th step.
The 3rd step, if initiator 1 receive that master controller 3 sends over search the detonator instruction time, initiator 1 sends to electric detonator and searches the detonator instruction, has judged whether the detonator response according to the detection control module that plays initiator 1 inside.Do not put and fill up quick-fried operation if there is detonator response then to carry out for the 7th step, otherwise carry out FOUR EASY STEPS.
The 4th step, the detonator address and the defer time of response are shown by the breath display module, the control module of initiator 1 inside is waited for the affirmation information of master controller input: if the affirmation information of receiving is to cancel the operation of detonating, then enter cancellation initiation control flow process, carried out for the 7th step; The operation if the affirmation information of receiving indication continues to detonate then enters and continues the state of detonating, and carries out for the 5th step.
In the 5th step, initiator 1 is waited for the instruction that powers on of detonating of master controller 3, if receive the instruction that powers on of detonating, then control module is opened the high pressure output channel and given the voltage that detonates on the electric detonator 8, carries out for the 6th step then.If do not receive the instruction that powers on of detonating, then control module keeps the detection voltage path unimpeded, waits for instruction.
