example 2 is a preferable example of example 1 to more specifically explain the present application.
The application reduces the working voltage of the detonating bus when the detonator and the electronic detonator module communicate, and the communication capacitor voltage is higher than the detonating bus voltage at the moment, so that the electronic detonator module completely depends on the communication capacitor to supply power without consuming the current on the detonating bus, thereby ensuring that bus current pulse is clearer when the electronic detonator module feeds back data, being more convenient for the detonator to identify and improving the reliability of communication.
Referring to fig. 1, the electronic detonator module is composed of a leg wire interface 101, a delay control circuit 102, a firing transduction element 103, a firing capacitor 104 and a communication capacitor 105. The delay control circuit 102 may be composed of an integrated special control chip, a discrete power supply circuit, an ignition circuit, a special delay control chip, and a microprocessor with a built-in delay control program; the communication capacitor 105 is connected with the foot line interface 101 through the delay control circuit 102; the ignition capacitor 104 is connected with the foot line interface 101 through the delay control circuit 102; the ignition transduction element 103 is connected to the ignition capacitor 104 through the delay control circuit 102.
Referring to fig. 2, an electronic detonator priming network constructed using the above-described electronic detonator modules is comprised of a detonator 201, a priming bus 202 and one or more electronic detonator modules 203 connected in parallel. Wherein, the exploder 201 is connected with each electronic detonator module 203 through an exploding bus 202; each of the electronic detonator modules 203 is connected to the detonation busbar 202 in parallel.
Referring to fig. 1, the electronic detonator module is connected in parallel to an electronic detonator priming network through a leg wire interface 101, and receives power supply and communication from a primer 201; the delay control circuit 102 receives an instruction from the electronic detonator priming network, controls the charging of the firing capacitor, and controls when the energy of the firing capacitor is released through the firing energy conversion element; the communication capacitor 105 is connected with the foot line interface 101 through the delay control circuit 102, when the initiator 201 supplies power to the electronic detonator module through the initiation bus 202, the voltage on the communication capacitor 105 is directly related to the voltage on the initiation bus 202, when the voltage of the initiator 201 for supplying power to the electronic detonator module through the initiation bus 202 is lower than the voltage on the communication capacitor 105, the electronic detonator module firstly consumes the electric quantity on the communication capacitor 105 until the voltage of the communication capacitor and the voltage of the electronic detonator module are the same again, and the electronic detonator module can not consume current from the initiation bus 202 again; the ignition capacitor 104 is connected with the foot line interface 101 through the delay control circuit 102, and when the initiator 201 sends a charging instruction through the initiation bus 202, the delay control circuit 102 charges the ignition capacitor 104; the ignition energy conversion element 103 is connected with the ignition capacitor 104 through the delay control circuit 102, when the initiator 201 sends out an initiation command through the initiation bus 202, the delay control circuit 102 judges according to the verification condition, and after the programmed delay time, the energy stored in the ignition capacitor 104 is controlled to be released through the ignition energy conversion element 103, so that the detonator is detonated.
The structure of the electronic detonator priming network referring to fig. 2, includes a primer 201, which is a device that supplies power to the electronic detonator priming network and can communicate with the electronic detonator priming network under the operation of a blasting worker; the initiator 201 is connected with the electronic detonator module 203 through the initiation bus 202, and the length of the initiation bus 202 can be changed according to actual use requirements, and the length varies from tens of meters to thousands of meters; the electronic detonator module 203, i.e. the electronic detonator module shown in fig. 1, may have one or more electronic detonator modules 203 in an electronic detonator initiation network, the specific number of which varies from one to thousands depending on the actual use requirements; each of the electronic detonator modules 203 is connected to the detonation busbar 202 in parallel.
The voltage on the initiation bus 202 is controlled by the initiator 201, and the initiator 201 supplies power to the electronic detonator initiation network in a mode that one bus voltage is working voltage and the other bus voltage is 0V; the initiator 201 sends a command (the sending command may also be referred to as a downlink communication) to the electronic detonator priming network in such a manner that the bus voltage having the original voltage of 0V is changed to the operation voltage (this may also be simply referred to as changing the bus polarity) by changing the bus voltage having the original voltage of the operation voltage to 0V. The voltage change on the initiation bus 202 during the change of the bus polarity is shown in fig. 3, where the voltage of bus a is 0V before time T1, the voltage of bus B is 0V after time T1, and the voltage of bus a is 0V.
The current on the initiation bus 202 is the sum of the currents consumed by all the electronic detonator modules 203 from the electronic detonator initiation network, and the electronic detonator modules 203 feed back to the initiator 201 (the feeding back may also be referred to as upstream communication) in a manner of greatly increasing their own current consumption in a short time (this manner may also be simply referred to as current pulse feeding back). Referring to fig. 4, it can be seen that the current before the time T1 and after the time T2 in the graph is the sum of the currents consumed from the electronic detonator priming network when each electronic detonator module 203 is static, and the current between the time T1 and the time T2 is the sum of the static currents and the current consumption increased by the electronic detonator module performing the current pulse feedback.
The initiator 201 first maintains the operating voltage of the initiation bus 202 at the supply voltage by the initiator 201 prior to communicating with the electronic detonator initiation network. When the initiator 201 starts to communicate with the electronic detonator priming network, the working voltage of the priming bus 202 is changed from the power supply voltage to the communication voltage by the initiator 201, and then the initiator 201 performs downlink communication to the electronic detonator priming network. If the command sent in the downlink communication needs uplink communication, the electronic detonator module 203 performs uplink communication to the electronic detonator priming network, and then the communication is ended; if the instruction sent in the downlink communication does not require the uplink communication, the communication is directly ended. Wherein the communication voltage is lower than the supply voltage. The process is described with reference to fig. 5. In the process of reducing the bus operation voltage from the power supply voltage to the communication voltage at the beginning of communication, referring to fig. 6, it can be seen that the bus operation voltage is reduced to the communication voltage at time T1 and the bus polarity is switched at time T2 to start communication.
Because the voltage of the communication capacitor 105 in the electronic detonator module is directly related to the voltage of the detonation bus 202, when the initiator 201 keeps the working voltage of the detonation bus 202 at the power supply voltage before communication starts, the voltage of the communication capacitor 105 reaches the power supply voltage; when communication is started, after the initiator 201 changes the working voltage of the initiating bus 202 from the power supply voltage to the communication voltage, the electronic detonator module consumes the electric quantity on the communication capacitor 105 at this time, and does not consume current from the initiating bus 202 because the voltage of the initiating bus 202 for supplying power to the electronic detonator module is lower than the voltage on the communication capacitor 105. At this time, if the uplink communication is performed, the current before the time T1 and after the time T2 (i.e., the sum of the currents consumed by the electronic detonator modules 203 during the static state) in fig. 4 is 0, so that the current between the time T1 and the time T2 (i.e., the current of the feedback pulse itself) is more obvious, which is more convenient for the initiator to recognize, thereby improving the reliability of the communication.
By adopting the structure that the communication capacitor supplies power to the electronic detonator module when the voltage of the detonating bus is lower, and combining the method of reducing the working voltage of the detonating bus before communication, the current consumed by each electronic detonator module from the electronic detonator detonating network becomes 0 when in static state in uplink communication, the problem that the current feedback pulse and the current consumed by each electronic detonator module from the electronic detonator detonating network are relatively close to each other and difficult to identify when in static state is solved, and the effect of improving the communication reliability of the electronic detonator detonating network is achieved.
