Furthermore, the particular features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples.

In a communication system such as an electronic detonator network and an intelligent sensing network, the energy required for maintaining the operation of each node slave is small, so that a master computer can directly provide an operating power supply for the slave computer conveniently, the maintenance of the network is facilitated, and the wiring of the network is simplified. In addition to this, in the above-mentioned type of communication system, it is also required that the slave is as small as possible. In the application of the electronic detonator, the requirement of the impact-resistant application environment of the electronic detonator needs to be considered, an on-chip RC oscillator which can be integrated is usually adopted as an operating clock, but the RC clock has the following defects: (1) when the integrated circuit is produced, certain deviation exists between chips with different absolute values of resistance and capacitance, and individual difference also exists between logic trigger voltages forming oscillation, and the clock deviation caused by the parameters is usually 10-20%; (2) in the application of the electronic detonator, the change of the environmental temperature exists, and the change of the environmental temperature usually causes the parameter change of the special integrated circuit of the electronic detonator, so that the working frequency is shifted.

In the related art, an electronic detonator priming system generally comprises an electronic detonator and an encoder. The initiator is used for registering, charging, testing, controlling the programming and initiation of the whole blasting network. When the electronic detonator is applied and the electronic detonator is registered by using the detonator, the detonator firstly acquires the RC clock period of the electronic detonator chip and stores the RC clock period in the detonator, and the detonator uses the clock period of the electronic detonator acquired during registration as the period when communicating with the electronic detonator. However, the conventional communication method has the following disadvantages: (1) due to the fact that the RC oscillator has the phenomena of logic trigger voltage difference, time drift and temperature drift, working frequency deviates, and the stability of an electronic detonator communication system is affected; (2) due to the error of the RC oscillator itself, when consecutive 0's or 1's are transmitted, a serious cumulative error occurs, resulting in erroneous initiator data received by the electronic detonator.

In order to solve the above problems, in the related art, bit sampling synchronization is performed by using an edge triggering method, so that accumulation of sampling errors is avoided, and the problem of clock skew caused by clock skew is solved. The edge triggering means that the discrimination of the data 0 and the data 1 is realized by adopting a mode of designating the high and low level widths of the data 0 and the data 1. However, this approach has the following disadvantages: due to the fact that the width of the data 0 and the width of the data 1 are specified, when the width of the data 0 is different from that of the data 1, when the detonator sends the data with the specified length, if the number of bits of the data 0 is different from that of the data 1, the data sent is unfixed, and therefore communication stability of the detonator and the electronic detonator is affected.

Based on the above, embodiments of the present invention provide an initiator data encoding method, an electronic device, and a storage medium. Initiator data refers to data sent by the initiator to the electronic detonator. According to the embodiment of the invention, the initial detonator data is obtained and encoded to obtain the encoded detonator data, and the encoded detonator data is sent to the electronic detonator. The data of the coded initiator comprises instruction bytes, the instruction bytes are used for controlling the operation of the electronic detonator by the initiator, the instruction bytes comprise data 0 and data 1, and the data 0 and the data 1 are consistent in width. According to the scheme, the width of the data 0 and the width of the data 1 in the instruction byte are consistent, when the initiator transmits data with the specified length, the length of the transmitted data is fixed no matter whether the number of bits of the data 0 and the number of bits of the data 1 are the same, and therefore the communication stability of the initiator and the electronic detonator is improved.

The following describes the technical aspects of the present invention with reference to specific embodiments.

In a first aspect, an embodiment of the present invention provides an initiator data encoding method, which is applied to an initiator in communication connection with an electronic detonator, where initiator data refers to data sent from the initiator to the electronic detonator. As shown in fig. 1, the method includes:

step S100: acquiring initial detonator data;

step S200: encoding the initial initiator data to obtain encoded initiator data; the data of the coded initiator comprises instruction bytes, the instruction bytes are used for controlling the operation of the electronic detonator by the initiator, the instruction bytes comprise data 0 and data 1, and the data 0 and the data 1 are consistent in width.

In some embodiments, the invention provides an initiator data encoding method, which includes acquiring initial initiator data, encoding the initial initiator data to obtain encoded initiator data, and sending the encoded initiator data to an electronic detonator. The data of the coded initiator comprises instruction bytes, the instruction bytes are used for controlling the operation of the electronic detonator by the initiator, the instruction bytes comprise data 0 and data 1, and the data 0 and the data 1 are consistent in width. According to the scheme, the width of the data 0 and the width of the data 1 in the instruction byte are consistent, when the initiator transmits data with the specified length, the length of the transmitted data is fixed no matter whether the number of bits of the data 0 and the number of bits of the data 1 are the same, and therefore the communication stability of the initiator and the electronic detonator is improved.

In some embodiments, as shown in FIG. 2A, a schematic of data 0 and data 1 is shown. Data 0 and data 1 represent 0 and 1 in binary. The data width of data 0 and data 1 is fixed (M1+ M2) T, T is integral multiple of the average clock period of the electronic detonator chip, and is usually 4, 8, 16 and 32 times. Preferably, M2>2M1 (the ratio interval is set to be 2-4 generally) may be set so that the widths of the high and low levels have a relatively distinct distinction, that is, the data 0 and the data 1 have a relatively distinct distinction, in order to avoid a recognition error due to waveform distortion and the like.

It is understood that in some embodiments, data 0 and data 1 may also be as shown in fig. 2B, as long as the widths of data 0 and data 1 are the same, and the widths of the high and low levels of the two have a clear distinction.

In some embodiments, as shown in FIG. 3, a schematic diagram of instruction bytes is provided. The instruction bytes include synchronization bits, instruction bits, and check bits. Wherein, the synchronization bit must include data 0 and data 1, and the widths of data 0 and data 1 are identical. The synchronous bit is mainly used for the electronic detonator to sample and learn the widths of the high level and the low level of the received data 0 or 1, and the problem of receiving accuracy caused by the deviation of an RC oscillator of the electronic detonator can be solved. Specifically, the electronic detonator respectively samples the widths of the high and low levels of data 0 and data 1 in the synchronization bit as criteria of 1 and 0 contained in the subsequently received command and data, for example, the widths of the high and low levels of the electronic detonator sampled data 0 are N1T 1(T1 is an electronic detonator sampling count clock) and N2T 1, respectively, the widths of the high and low levels of the sampled data 1 are N3T 1 and N4T 1, respectively, it is of course required that N1+ N2 be substantially equal to N3+ N4, a certain deviation, for example, 10%, is allowed, and later, when receiving 1 and 0 in the command data and K bytes of data packets, the widths of the sampled high and low levels are N5T 1 and N6T 5, respectively, and then it is determined whether the value of N5 is within the range of 10% of N1 or N3, and whether the value of the error of N6342 is within the range of N599% or N599, or received is an interference pulse.

The content of the instruction bit is an instruction which is output by the initiator and used for controlling the electronic detonator, such as: the method comprises the steps of reading an electronic detonator internal code instruction, writing an electronic detonator delay time instruction, calibrating an electronic detonator delay instruction, reading an electronic detonator delay instruction, an electronic detonator internal test instruction, an electronic detonator state reading instruction, an electronic detonator decryption instruction, an electronic detonator roll call instruction, an electronic detonator leak detection instruction, a detonation instruction sequence and the like. In addition, the detonators with mutually independent working capacitance and initiation capacitance of the electronic detonators can also comprise a charging instruction and a safe discharging instruction. In some embodiments, for the instruction BIT of 6BIT, the 6BIT data expression is 000000B to 111111B, and 64 binary combination data coexist, so that 64 instructions can be represented, namely, 64 operations can be controlled by the detonator.

The check bits are usually odd check or even check or parity check, and the check is performed according to the number of data 1 in a group of transmitted binary codes, which is an odd number or an even number, and is mainly used for checking whether the instruction byte is accurate.

In some embodiments, the coded initiator data further includes a communication start bit for indicating a start of transmission of the coded initiator data and a communication stop bit for indicating a stop of transmission of the coded initiator data.

In some embodiments, the beginning portion of the encoded initiator data is further augmented with a communication start bit and the ending portion is further augmented with a communication stop bit. The communication start bit has a width clearly distinguished from data 0 and data 1, which expresses that data is transmitted from the next rising edge. In the related art, generally, each byte of data has a stop bit, and therefore, when a packet of data is transmitted, the stop bit of each byte of data needs to be detected, which results in inefficient communication. In the embodiment, the communication stop bit is added to the end part of the data of the coding initiator, the data of each byte does not need to be detected, and the communication efficiency can be improved. And the communication stop bit indicates that the data of the initiator is sent completely, and the electronic detonator is informed to execute corresponding operation, so that the electronic detonator stops receiving the data as long as the communication stop bit is detected, and the stability and reliability of communication are improved.

In some embodiments, as shown in fig. 4, a schematic diagram of the communication start bit is shown. The communication start bit includes a falling edge and a low level having a width not less than 2(M1+ M2) T. It should be noted that the high level in fig. 4 before the falling edge is to provide power to the electronic detonator before the initiator data is sent. In the present embodiment, for the sake of easy identification, it is required that the low level width is not less than 2 times (i.e., 2(M1+ M2) T) of the width of data 0 or data 1 in consideration of the deviation of the RC clock because the start bit of the normal data is 1-bit half data, i.e., 1.5, whereas in the present embodiment, in consideration of the fact that the electronic detonator has not yet performed the learning of data bits when transmitting the initiator data, while the RC clock of the electronic detonator usually has an individual deviation of 20%, in order to make the initiator data transmitted by the initiator better adapt to electronic detonators of different frequencies, the width of the communication start bit is set to not less than 2(M1+ M2) T.

In some embodiments, as shown in FIG. 5, a schematic diagram of a communication stop bit is shown. The communication stop bit includes a rising edge and a high level, and the width of the high level is not less than 1.5(M1+ M2) T.

In some embodiments, the communication stop bit indicates that the initiator stopped sending data with 1 rising edge + a width equal to or greater than 1.5 times the data 0 or the data 1.

In some embodiments, the encoded initiator data further comprises data bytes for indicating data to be sent for execution of the instruction corresponding to the instruction bytes.

In some embodiments, the encoded initiator data further comprises data bytes. The initiator determines whether to send data subsequently according to different instruction bytes, for example, a write delay instruction, and continues to send K delay time data after the instruction bytes are sent, wherein the sent data includes delay time or a detonator sequence code, a detonation password, an electronic detonator register address and the like or a combination thereof.

In some embodiments, the data bytes include data bits and check bits. The data bits contain the data to be transmitted and the check bits are used primarily to check whether the data bytes are accurate.

In connection with the above embodiments, as shown in fig. 6, a complete schematic diagram of encoding initiator data is shown, including a communication start bit, an instruction byte, a data byte, and a communication stop bit.
