Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
In a first embodiment of the present invention, a method for reporting a measured voltage of an electronic detonator is provided, and specifically, referring to fig. 1, the method includes the following steps:
step S11: after the electronic detonator detects and records the binary value of the working voltage, a voltage reporting instruction that the host computer requires to feed back the preset voltage is received, and the working voltage detected by the electronic detonator comprises bus voltage, self-charging voltage and the like.

Step S14: if a voltage feedback signal for feeding back the last numerical value of the binary value of the working voltage is sent to the host computer in the last feedback time slot of the feedback time window, the slave computer is marked as a preset voltage and the identity information is reported to the host computer.
The electronic detonators in the embodiment of the invention receive a voltage reporting instruction sent by a host after acquiring the working voltage of the electronic detonators, such as bus voltage or charging voltage, and then judge whether a voltage feedback signal for feeding back binary value corresponding bit values of the working voltage needs to be sent to the host or not according to the voltage reporting instruction in a feedback time window, the host can obtain a binary detection result of the preset voltage after the feedback time window is finished, and simultaneously obtain the identity information of a slave under the preset voltage, so that the host can determine which detonators are under the preset voltage range, therefore, each electronic detonator in a detonation network does not need to be reported one by one and then judged by the host after detecting the voltage, but the slave self judges and finishes voltage reporting in the communication process according to on-line information, and the host can determine whether to continue working or modify a construction scheme according to the reported result, the safety and the reliability of the whole detonation network are ensured, and meanwhile, the communication time is saved.
In a preferred embodiment of the present invention, the voltage reporting instruction received by the electronic detonator includes: the electronic detonator can know which detection range the host requires to feed back the preset voltage, and in each feedback time slot of the feedback time window, the electronic detonator sequentially judges whether a voltage feedback signal for feeding back a bit value corresponding to a binary value of the working voltage needs to be sent to the host according to the preset voltage detection instruction and the instruction parameter code from high to low according to the bit.
Further, the electronic detonator, according to the predetermined voltage detection instruction and the instruction parameter code, sequentially judges whether a voltage feedback signal for feeding back a value of a corresponding bit of the binary value of the working voltage needs to be sent to the host computer after the binary value of the working voltage is sent from high to low according to the bit, and before the next feedback time slot comes, further comprises: and judging whether a feedback flag signal sent by the host after receiving the voltage feedback signal is received, if so, sending the voltage feedback signal in the current feedback time slot, waiting for the arrival of the next feedback time slot, and judging whether a voltage feedback signal for feeding back the corresponding bit value of the working voltage binary value needs to be sent to the host in the next feedback time slot. Before the next feedback time slot comes, the method further comprises the following steps: if the feedback mark signal sent by the host after receiving the voltage feedback signal is not received, waiting for the arrival of the next feedback time slot, and judging whether a voltage feedback signal for feeding back the corresponding bit value of the working voltage binary value needs to be sent to the host or not in the next feedback time slot.

In addition, before the step S14, before the step S, where the slave is marked to have the predetermined voltage and reports the identity information to the master, the method further includes: if the last feedback time slot of the feedback time window is finished, the feedback mark signal is not received, and the last feedback time slot does not set the slave to be in the standby state, the slave is marked to be the preset voltage slave and reports the identity information to the host.
Optionally, if the detection range of the predetermined voltage detection instruction includes a lowest voltage detection instruction or a highest voltage detection instruction, in step S14, if the electronic detonator sends a voltage feedback signal for feeding back a final value of a binary value of the working voltage to the host in a last feedback time slot of the feedback time window, or, if the last feedback time slot of the feedback time window is over, no feedback flag signal is received, and when the last feedback time slot does not set itself to be in a standby state, the electronic detonator marks itself as a lowest voltage slave or a highest voltage slave and reports identity information to the host, so that the host can acquire the slave in the highest voltage or the lowest voltage range in the priming network, and since the electronic detonator with too high or too low voltage affects the working performance of the detonator itself and affects the reliability of the whole priming network, the host machine can remove unqualified electronic detonators and adjust the construction scheme according to the obtained highest or lowest voltage value and the identity information of the electronic detonators under the corresponding voltage value, so that the safety and the reliability of the whole detonation network are guaranteed.
Specifically, when the detection range of the predetermined voltage detection instruction includes the lowest voltage detection instruction, if the binary bit value of the corresponding bit of the working voltage of the electronic detonator is 0, a voltage feedback signal for feeding back the value of 0 is sent to the host, and if the host receives the voltage feedback signal, the value of the corresponding bit of the binary detection result of the predetermined voltage is set to 0, otherwise, the value is set to 1. When the detection range of the preset voltage detection instruction comprises a highest voltage detection instruction, if the binary bit value of the corresponding bit of the working voltage of the electronic detonator is 1, a voltage feedback signal for feeding back the value 1 is sent to the host, at the moment, if the host receives the voltage feedback signal, the number of the corresponding bit of the binary detection result of the preset voltage is set to 1, otherwise, the number is set to 0, and so on, and the host can obtain the binary detection result of the preset voltage after the feedback time window is ended.
In order to make the embodiment of the invention clearer, a use scene that a host is connected with a plurality of electronic detonators through a bus is taken as an example, a detection range of a preset voltage detection instruction received by each electronic detonator comprises a lowest voltage detection instruction, the action of reporting the execution of the electronic detonator in a first feedback time slot of a feedback time window is concretely described, an instruction parameter code is provided with a value matched with the lowest voltage detection instruction, when the electronic detonator knows that the host requires to feed back the lowest voltage according to the instruction parameter code, in the first feedback time slot of the feedback time window, if the highest position of a binary value of the working voltage of the electronic detonator is to be fed back (the numerical values of the binary value are sequentially fed back from the high position to the low position in each feedback time slot) is 0, a voltage feedback signal for feeding back the highest position of the binary value of the working voltage is 0 is sent to the host, the host computer receives the voltage feedback signal, the numerical value of the highest bit of the binary detection result of the lowest voltage is set to be 0, before the next feedback time slot arrives, if the feedback mark signal sent by the host computer after receiving the voltage feedback signal is received and the signal is also fed back by the host computer, or the voltage feedback signal is not received, the arrival of the next feedback time slot is waited, the feedback rule is repeatedly executed in the next feedback time slot, and so on, each detonator in the detonation network is executed according to the rule in each other feedback time slot, and the description is omitted. If a feedback flag signal sent by the host after receiving the voltage feedback signal is received and a signal is not fed back by the host (that is, the bit value of the first bit to be fed back by the working voltage is 1 in the first feedback time slot, but other detonators feed back the voltage feedback signal), the host is set to be in a standby state, and the host does not wait for the next feedback time slot but waits for other instructions, so that the detection efficiency of the host and the communication efficiency of the whole detonation network are improved. After the feedback time window is finished, if the host computer sends a voltage feedback signal for feeding back the last bit value of the binary value of the working voltage in the last feedback time slot of the feedback time window, or the last feedback time slot is finished, no feedback mark signal is received, and the host computer is marked as the lowest voltage slave computer and reports the identity information to the host computer when the host computer is not set to be in the standby state in the last feedback time slot, therefore, the host computer can know the reporting result of which electronic detonators are the lowest voltage slave computers, and then the host computer determines to continue working or modify the construction scheme according to the reporting result, thereby ensuring the safety and reliability of the whole detonation network and saving the communication time.
Optionally, the host further provides an error correction feedback time window after the feedback time window is ended; after the electronic detonator marks the slave machine with the preset voltage, if an error correction detection instruction sent by the host machine is received, the electronic detonator reports a first CRC check value of a binary value of the working voltage recorded by the electronic detonator in an error correction feedback time window, so that the host machine judges whether a reporting error exists according to the received first CRC check value and a second CRC check value of a binary detection result of the preset voltage, and therefore the host machine can judge whether the reporting error is caused by communication interference or slave machine state abnormity in the receiving process, and accuracy of the reported voltage is guaranteed.

Before the next feedback time slot comes, the communication module 13 further performs the following steps: if the feedback mark signal sent by the host after receiving the voltage feedback signal is not received, waiting for the arrival of the next feedback time slot, and judging whether a voltage feedback signal for feeding back the corresponding bit value of the working voltage binary value needs to be sent to the host or not in the next feedback time slot. In order to further improve the communication efficiency of each electronic detonator in the detonation network, save the communication time of the host, and improve the detection efficiency, the communication module 13 further executes the following steps before the next feedback time slot arrives: if a feedback flag signal sent by the host after receiving the voltage feedback signal is received and no voltage feedback signal is sent in the current feedback time slot, the communication module 13 does not need to receive the feedback flag signal and judge whether to send the voltage feedback signal after the communication module is set in the standby working state without waiting for the arrival of the next feedback time slot and setting the communication module into the standby working state, so that the detection efficiency of the host is improved.
In addition, before the storage module 12 of the electronic detonator control chip marks that the storage module is a slave with a preset voltage and reports the identity information to the host, the method also comprises the following steps: if the last feedback time slot of the feedback time window is finished, the communication module 13 does not receive the feedback flag signal, and when the last feedback time slot does not set itself to be in the standby state, the communication module 12 marks itself as a slave with a predetermined voltage and reports the identity information to the master.

the detection mechanism for detecting the bus voltage and the charging voltage of the electronic detonator is as follows: the host computer sends out a broadcast command to require the electronic detonators to detect the power supply voltage or the charging voltage of the electronic detonators, and each electronic detonator control chip detects and records the measurement result.
The reporting mechanism of the working voltage detected by each generator detonator in the detonation network is as follows:
the host computer sends out a detection instruction, adds a parameter code (i.e. the instruction parameter code in the first embodiment, and is hereinafter referred to as the instruction parameter code for the purpose of making the scheme clear), and then provides a certain feedback time window for the electronic detonator module.
Taking an 8-BIT voltage measurement result as an example (that is, when the working voltage detected by the electronic detonator is a binary detection result of 8 BITs), if the host requires that the feedback predetermined voltage is the lowest voltage, the host sends a detection command first, then sends a command parameter code 00, then provides a feedback time window, the electronic detonator (hereinafter, generically referred to as a slave) with the highest BIT8 of 8 BITs 0 sends a voltage feedback signal in the first time slot T1 of the feedback window, the host detects the signal and then sets the highest BIT LVM _ BIT8 of the lowest voltage detection result LVM to 0, and sends a feedback flag signal in the time slot R1 before the end of T1 and the start of T2, if the slave detects the signal in R1, it is indicated that the time slot T1 has been fed back by the slave, then all the slaves with BIT8 of 1 will enter a standby state to wait for other commands (no result is fed back in the time slots T2-T8), and the slave 8 is a slave of 0, it will continue to wait for the T2 slot and BIT7 will be the slave feedback of 0 when T2 arrives.
If the master does not receive the voltage feedback signal fed back by any slave after the T1 is finished, setting the highest BIT LVM _ BIT8 of the LVM with the lowest voltage detection result to be 1, not sending a feedback mark signal in the time slot R1 before the T1 is finished and the T2 is started, and if the slave does not receive any feedback mark signal in the time slot R1, waiting for the T2 to arrive by all the slaves and finishing the action according to the rule.
And repeating the above steps until the time slot T8 is finished, wherein the LVM value recorded by the master is the lowest voltage value, all slaves feeding back 0 signals in the time slot T8, or slaves which do not receive the master signals in the time slot R8 and do not enter the standby state in the time slot T8 are marked as lowest voltage slaves, and the master can request the slaves (i.e., identity information) to report their IDs through other commands, so that the master knows which slaves are in the lowest voltage state.
In the R9 time slot, the host can choose whether to correct the error, if not, in the R9 time slot, the host does not send the feedback mark signal, and the slave does not receive the mark in the R9 time slot, then the reporting process is stopped, and the slave enters the waiting instruction state. If error correction is carried out, the host computer requests all slave computers marked as the lowest voltage at a time slot T9 in a mode of continuously sending a feedback mark signal, a CRC check value corresponding to the LVM value of the working voltage recorded by the host computer is reported, and the host computer receives the CRC check value and compares the CRC check value with the CRC check value of the LVM value of the lowest voltage detection result recorded by the host computer so as to judge whether reporting errors are caused by communication interference or slave computer state abnormity in the receiving process. After the time slot T9 is over, the slave enters a wait state, regardless of whether it is faulty or not. The host determines whether to report the voltage again according to the use requirement.
If the highest voltage is to be detected, 0 and 1 in the above description are interchanged and the command parameter code sent at the same time is changed to 11.
It can be seen that after the slave machines in the embodiment of the present invention detect the operating voltages, the slave machines do not need to report their operating voltages one by one and then judge by the host machine, but the slave machines self-judge and complete voltage reporting according to the on-line information in the communication process, and can also complete reporting of slave machine IDs after voltage reporting, so that the host machine knows which slave machines are at the highest or lowest voltage, and the host machine determines to continue working or modify the construction scheme according to the obtained reporting result, thereby ensuring the safety and reliability of the whole detonation network, and saving the communication time.
It should be noted that, in the embodiment of the present invention, how the master sends a signal, how the slave feeds back a signal, may be freely defined, and the present invention only defines the result and meaning of the feedback and sending, and the same scheme as the present invention expresses the result, regardless of the specific communication method, is a derivative scheme of the present invention. The method for detecting the voltage from the slave in the invention can use ADC (analog-to-digital converter), and can also use a comparator and the like. The minimum voltage and the maximum voltage in the invention can be in other meanings, and the scheme can be adopted as long as the scheme has size comparison and requires reporting of an extreme value.
In a specific case, if the master wants to detect the voltage in the range, the master sends a detection command and a command parameter code 01, then sends 8-bit upper limit voltage value VH and lower limit voltage value VL, and the feedback window is only provided with three windows of T1, T2 and T3, in the window of T1, all slaves receiving the command and slaves having a voltage range between VH and VL have a feedback signal marked as in-range slaves by an internal memory, and in the window of T2, all slaves receiving the command and have a voltage higher than VH, and in the feedback signal mark itself as out-of-range high-voltage slaves by the internal memory. Then in the window of T3, all slaves that receive the command, and slaves with lower voltage than VL, feed back the signal and mark themselves as out-of-range low voltage slaves through internal memory. The master may request the slave(s) to report their own ID via other corresponding instructions.
