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, referring specifically 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, the voltage reporting instruction of the host requiring feedback of the preset voltage is received, and the working voltage detected by the electronic detonator comprises bus voltage, self-charging voltage and the like.
Step S12: and entering a feedback time window required by reporting provided by the host, wherein the feedback time window is provided with a plurality of feedback time slots with the same number as the binary bit number of the binary value, for example, the binary value is an 8-bit voltage measurement result, and eight feedback time slots can be correspondingly arranged in the feedback time window.

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 in the last feedback time slot of the feedback time window, the host is marked as a preset voltage slave and identity information is reported to the host.
After the working voltage such as the bus voltage or the charging voltage of the electronic detonator is obtained, the voltage reporting instruction sent by the host computer is received, then whether a voltage feedback signal for feeding back the corresponding bit value of the binary value of the working voltage is required to be sent to the host computer is judged according to the voltage reporting instruction in a feedback time window, the host computer can obtain the binary detection result of the preset voltage after the feedback time window is finished, and meanwhile, the identity information of the slave computer under the preset voltage is obtained, so that the host computer can determine which detonators are in the preset voltage range, and therefore, each electronic detonator in the detonation network does not need to be reported one by one after the detection voltage, but is judged by the host computer according to the line reporting information in the communication process, and the host computer can determine whether 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.
In a preferred embodiment of the present invention, the voltage report instruction received by the electronic detonator includes: the electronic detonator can know which detection range the host requires to feed back the preset voltage under, and in each feedback time slot of the feedback time window, the electronic detonator sequentially judges whether to send a voltage feedback signal for feeding back the corresponding bit value of the binary value of the working voltage to the host from high to low according to the preset voltage detection command and the command parameter.
Further, after the electronic detonator sequentially judges whether to send a voltage feedback signal for feeding back the corresponding bit value of the binary value of the working voltage to the host according to the preset voltage detection instruction and the instruction parameter code from high to low, before the next feedback time slot comes, the electronic detonator further comprises: judging whether a feedback mark signal sent by the host after receiving the voltage feedback signal is received, if yes, 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 binary value of the working voltage is needed to be sent to the host 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, 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 received and the voltage feedback signal is not sent out in the current feedback time slot, the arrival of the next feedback time slot is not waited, the host is set to be in a standby working state, the feedback mark signal is not needed to be received and whether the voltage feedback signal is sent or not is judged after the host is set to be in the standby working state, and therefore the detection efficiency of the host is improved.
In addition, in step S14, before marking itself as a slave with a predetermined voltage and reporting identity information to the master, the method further includes: if the last feedback time slot of the feedback time window is finished, a feedback mark signal is not received, and when the last feedback time slot is not set to be in a standby state, the self is marked as a preset voltage slave and identity information is reported to the host.
Optionally, the detection range of the predetermined voltage detection command includes a minimum voltage detection command or a maximum voltage detection command, if in the last feedback time slot of the feedback time window, the electronic detonator sends a voltage feedback signal for feeding back the final value of the working voltage binary value to the host, or when the last feedback time slot of the feedback time window ends, a feedback flag signal is not received, and when the last feedback time slot does not set itself to a standby state, the electronic detonator is marked as the minimum voltage slave or the maximum voltage slave and reports identity information to the host, thereby, the host can obtain the slave in the detonating network under the maximum voltage or the minimum voltage range, and as the working performance of the electronic detonator with too high or too low voltage can affect the reliability of the whole detonating network, the host can reject unqualified electronic detonators and adjust the construction scheme according to the obtained voltage value of the maximum or minimum voltage and the identity information of the electronic detonator under the corresponding voltage value, thereby ensuring the safety and reliability of the whole detonating network.
Specifically, when the detection range of the predetermined voltage detection command includes the lowest voltage detection command, 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 0 value 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 of the corresponding bit of the binary detection result of the predetermined voltage is set to 1. When the detection range of the preset voltage detection instruction comprises the 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 with a feedback value of 1 is sent to the host, at this time, 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, 0 is set, and the host can obtain the binary detection result of the preset voltage after the feedback time window is finished.
In order to make the embodiment of the invention clearer and more obvious, taking a use scenario that a host is connected with a plurality of electronic detonators through a bus, taking a case that a detection range of a preset voltage detection instruction received by each electronic detonator includes a lowest voltage detection instruction as an example, a specific explanation is made on an action that the electronic detonator executes reporting in a first feedback time slot of a feedback time window, an instruction parameter number is set with a value matched with the lowest voltage detection instruction, when the electronic detonator acquires that the host requires the lowest voltage to be fed back according to an instruction parameter code, in a first feedback time slot of the feedback time window, if the highest bit of an electronic detonator working voltage binary value is to be fed back (the numerical value of each numerical value of the binary value is sequentially fed back from the higher bit to the lower bit in each feedback time slot) is 0, a voltage feedback signal for feeding back the highest bit of the working voltage binary value is sent to the host, the host receives the numerical value of the highest bit of the lowest voltage feedback signal, before the next feedback time slot arrives, if the host receives a feedback flag signal sent after receiving the voltage feedback signal, or the host does not receive feedback signal in the next feedback time slot, feedback rules are repeated, and the feedback rules are not carried out in the next feedback time slot, and the feedback rules are repeated. If the feedback mark signal sent by the host after receiving the voltage feedback signal is received and the feedback mark signal is not fed back (namely, the bit value of the first bit to be fed back of the working voltage in the first feedback time slot is 1, 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 electronic detonator sends out 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, a feedback mark signal is not received, and when the last feedback time slot does not set the electronic detonator to be in a standby state, the electronic detonator is marked as the lowest voltage slave and identity information is reported to the host, so that the host can know which electronic detonator is the reporting result of the lowest voltage slave, and further decides to continue working or modify a construction scheme according to the reporting result, thereby ensuring the safety and reliability of the whole detonation network and saving communication time.
Optionally, the host computer further provides an error correction feedback time window after the feedback time window is finished; after the electronic detonator marks itself as the slave machine of the preset voltage, if an error correction detection instruction sent by the host machine is received, reporting the first CRC check value of the 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 reporting errors exist according to the received first CRC check value and the second CRC check value of the binary detection result of the preset voltage, and therefore, the host machine can judge whether communication interference exists in the receiving process or reporting errors are caused by the state abnormality of the slave machine, and the accuracy of reporting the voltage is ensured.
After the electronic detonator in the embodiment of the invention acquires the working voltage such as bus voltage or charging voltage, the voltage reporting instruction sent by the host is received, the voltage reporting instruction contains a preset voltage detection instruction and instruction parameter codes for identifying the detection range of the preset voltage detection instruction, if the detection range of the preset voltage detection instruction is the highest voltage detection instruction or the lowest voltage detection instruction, the detection instructions in different detection ranges are distinguished by setting different instruction parameter codes, so that the electronic detonator can acquire whether the host requires to feed back the highest voltage or the lowest voltage through the instruction parameter codes, then determine whether to send a voltage feedback signal for feeding back the corresponding bit value of the binary value of the working voltage to the host in a feedback time window, the host can acquire the binary detection result of the preset voltage after the feedback time window is finished, and meanwhile acquire the identity information of the slave under the preset voltage to determine which detonators are under the preset voltage range, and therefore, each electronic detonator in the detonation network can self-judge and complete the voltage reporting according to the information on line in the communication process, and the host can determine whether to continue working or modify the construction scheme according to the reporting result, so that the safety and the reliability of the whole detonation network are ensured, and the time is saved.

If the communication module 13 sends a voltage feedback signal for feeding back the last value of the binary value of the working voltage to the host in the last feedback time slot of the feedback time window, the electronic detonator control chip marks itself as a preset voltage slave through the storage module 12 and reports identity information to the host through the communication module 13.
The electronic detonator control chip provided by the embodiment of the invention enables the electronic detonator adopting the chip to self-judge and complete voltage reporting according to the on-line information in the communication process, and the host decides whether to continue working or modify the construction scheme according to the acquired reporting result, thereby ensuring the safety and reliability of the whole detonation network and saving the communication time.

Wherein the communication module 13 further performs the method of the following steps before the next feedback slot arrives: 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 binary value of the working voltage needs to be sent to the host 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, improve the detection efficiency, before the next feedback time slot arrives, the communication module 13 further executes the following steps: if the feedback flag signal sent by the host after receiving the voltage feedback signal is received and the voltage feedback signal is not sent in the current feedback time slot, the host does not wait for the arrival of the next feedback time slot, and sets itself to a standby working state, and the communication module 13 does not need to receive the feedback flag signal and judge whether to send the voltage feedback signal or not after setting itself to the standby working state, thereby improving the detection efficiency of the host.
In addition, before the storage module 12 of the electronic detonator control chip marks itself as a preset voltage slave and reports the identity information to the host, the following steps are further executed: if the last feedback time slot of the feedback time window ends, the communication module 13 does not receive the feedback flag signal, and when the last feedback time slot does not set itself to the standby state, the storage module 12 marks itself as a slave with a predetermined voltage and reports identity information to the host.
Optionally, the detection range of the predetermined voltage detection command includes a minimum voltage detection command or a maximum voltage detection command, and if the communication module 13 sends a voltage feedback signal for feeding back the last value of the binary value of the working voltage to the host in the last feedback time slot of the feedback time window, or when the last feedback time slot of the feedback time window ends, no feedback flag signal is received, and when the last feedback time slot does not set itself to a standby state, the electronic detonator control chip marks itself as the minimum voltage slave or the maximum voltage slave through the storage module 12 and reports identity information to the host.
Optionally, after the feedback time window is finished, the host computer further provides an error correction feedback time window, and after the electronic detonator control chip marks itself as the slave computer with the preset voltage through the storage module 12, if an error correction detection instruction sent by the host computer is received, the first CRC check value of the binary value of the working voltage recorded by the host computer is reported in the error correction feedback time window, so that the host computer judges whether reporting errors exist according to the received first CRC check value and the second CRC check value of the binary detection result of the preset voltage, and therefore, the host computer can judge whether communication interference exists in the receiving process or the slave computer status is abnormal to cause reporting errors of the slave computer, thereby ensuring the accuracy of reporting the voltage.
In order to make the present invention more clear, a third embodiment of the present invention is described as a specific implementation of the present invention in a practical application scenario based on the two embodiments.
The exploder (host) is connected with the electronic detonator serving as the slave machine through the double buses to form an exploding network so as to supply power and control communication to the electronic detonator. The electronic detonator (slave) has the functions of detecting bus voltage, charging self energy storage capacitor and detecting charging voltage value,
the detection mechanism of the bus voltage and the charging voltage of the electronic detonator is as follows: the host sends out a broadcast instruction to require the electronic detonator to detect the power supply voltage or charging voltage of the host, and each electronic detonator control chip detects and records the measurement result.
The reporting mechanism of the working voltage detected by each power generation sub detonator in the detonation network is as follows:
the host computer issues a detection instruction, and attaches a parameter number (i.e., the instruction parameter number in the first embodiment, hereinafter, collectively referred to as the instruction parameter number for clarity of the scheme), and then provides a certain feedback time window for the electronic detonator module.
Taking an 8-BIT voltage measurement result as an example (namely, when the working voltage detected by the electronic detonator is an 8-BIT binary detection result), if the host computer requires that the predetermined voltage fed back is the lowest voltage, a detection instruction is firstly sent, then an instruction parameter number 00 is sent, then a feedback time window is provided, an electronic detonator (hereinafter referred to as a slave computer) with the highest BIT8 of 0 in the first time slot T1 of the feedback window sends a voltage feedback signal, after the host computer detects the signal, the highest BIT LVM_BIT8 of the lowest voltage detection result LVM is set to 0, and a feedback flag signal is sent in the time slot R1 before the end of T1 and the beginning of T2, if the slave computer detects the signal in the R1, then the slave computers with the BIT8 of 1 enter a standby state to wait for other instructions (no longer feeds back any result in the time slot T2-T8), the slave computers with the BIT8 of 0 continue to wait for the time slot T2, and when the slave computers with the BIT7 of 0 come.
If the master machine does not receive any slave machine feedback voltage feedback signals after the end of the T1, the highest BIT LVM_BIT8 of the lowest voltage detection result LVM is set to be 1, no feedback mark signal is sent out in a time slot R1 before the end of the T1 and the beginning of the T2, and all slave machines wait for the arrival of the T2 and complete the action according to the rules.
And the like until the T8 time slot is finished, the LVM value recorded by the host is the lowest voltage value, and all slaves feeding back a 0 signal in the T8 time slot or slaves which do not receive the host signal in the R8 time slot and do not enter a standby state in the T8 time slot are marked as the lowest voltage slaves, so that the host can request the slaves (or the slaves) to report own IDs (i.e. identity information) through other instructions so as to know which slaves are in the lowest voltage state.
In the R9 time slot, the host computer can choose whether to correct the error, if not, in the R9 time slot, the host computer does not send a feedback mark signal, and the slave computer stops the reporting process and enters a waiting instruction state when not receiving the mark in the R9 time slot. If error correction is performed, the host computer requests that all slaves marked with the lowest voltage report the CRC value corresponding to the LVM value of the working voltage recorded by the host computer in the T9 time slot by continuously sending the feedback mark signal, and the host computer receives the CRC value and compares the CRC value with the CRC value of the LVM value of the lowest voltage detection result recorded by the host computer, so as to judge whether communication interference exists in the receiving process or report errors are caused by the state abnormality of the slaves. The slave enters a wait instruction state after the end of the T9 slot, whether erroneous or not. The host computer decides whether to report the voltage again according to the use requirement.
If the highest voltage is to be detected, 0 and 1 are interchanged in the above description, and the instruction parameter number sent is changed to 11.
Therefore, after each slave in the embodiment of the invention detects the working voltage, the slave does not need to report the working voltage one by one and then judge by the host, but the slave can judge and finish voltage report according to online information in the communication process, and can finish reporting the slave ID after the voltage report, so that the host knows which slaves are under the highest or lowest voltage, and the host decides to continue working or modify the construction scheme according to the acquired report 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 and how the slave feeds back a signal can be freely defined, and the present invention only defines the feedback and the sending result and meaning, and the scheme identical to the expression result of the present invention, regardless of the specific communication method, is the derivative scheme of the present invention. The method for detecting the voltage by the slave machine can use an ADC (analog-to-digital converter), a comparator and the like. The minimum and maximum voltages in the present invention may be any other voltages, and any voltage may be used as long as they have a comparison in magnitude and require reporting of an extreme value.
In addition, in a specific case, if the host computer is to detect the voltage in the range, the host computer sends a detection command and command parameter number 01, then sends an 8-bit upper limit voltage value VH and a lower limit voltage value VL, meanwhile, a feedback window is only provided with three windows of T1, T2 and T3, in the T1 window, all slaves receiving the command and the voltage range is between VH and VL, a feedback signal marks itself as an in-range slave through an internal memory, then in the T2 window, all slaves receiving the command and the voltage is higher than VH, and the feedback signal marks itself as an out-of-range high voltage slave through the internal memory. Thereafter, in the T3 window, all slaves receiving the command and having a voltage lower than VL, feed back the signal and mark themselves as out-of-range low voltage slaves via the internal memory. The master may ask the slave(s) to report its own ID via other corresponding instructions.
