In the specific implementation, in step 101, the writing data to the electronic detonator necessarily includes function code data and parameter code data, the function code data is sent to the electronic detonator to inform the electronic detonator of the writing data, and the parameter code data is sent to the electronic detonator to inform the electronic detonator of the data to which the function code data should be written. For example, the function code data is a written network serial number, and the parameter data is a network serial number. When the electronic detonator is transmitted, the functional code data is transmitted firstly, then the parameter data is transmitted, and the parameter data is written into the corresponding position of the electronic detonator according to the functional code data after the electronic detonator receives the parameter data.
The function code data and the parameter code data are converted into corresponding communication waveforms, the communication waveforms adopt fixed writing clock frequency, the fixed writing clock frequency is used for judging whether the communication waveforms are abnormal or not by the electronic detonator, packet loss and error rate are greatly reduced in a communication interference environment, communication distance is farther, and communication is more stable, and in one embodiment, the function code data and the parameter code data are converted into corresponding communication waveforms, and the method comprises the following steps:
converting bit data 1 in the functional code data and the parameter digital data into square waves with a first proportion of duty ratio;
the bit data 0 in the function code data and the parameter code data are converted into square waves with a second proportion of duty ratio.
In the above embodiment, fig. 2 is an example of a communication waveform in the embodiment of the present invention, where the communication waveform includes square waves with a plurality of fixed periods, and one period starts from a rising edge and ends until the next rising edge; in one communication period, a configuration is defined in which a high-level duty ratio is a first ratio (for example, 33%) representing bit data 1 and a high-level duty ratio is a second ratio (for example, 67%) representing bit data 0; the communication period defining bit data 1 or 0 is equal (e.g., 1 ms), indicating a fixed write clock frequency. In fig. 2, before transmitting the function code data and the parameter code data such as bit data 0 or 1, a starter signal is also transmitted to the electronic detonator for notifying that the electronic detonator is ready for communication. FIG. 3 is a schematic waveform diagram of a parameter data written into one byte according to an embodiment of the present invention, as shown in FIG. 3, the function code data is one byte, 8 bits of data (i.e. one byte is composed of eight binary bits), and similarly, the parameter data of one byte is composed of 8 bits of data; defining each bit data of one byte as B7 to B0, wherein the most significant bit is B7 and the least significant bit is B0; after the electronic detonator recognizes the function code data, the electronic detonator starts to write the parameter code data, and each byte of the parameter code data is written once according to the sequence that the high bit is in front and the low bit is in back; after the first byte is written, writing the second byte and the third byte sequentially until the writing is completed and the idle state is entered; in the embodiment of the invention, the length of the function code data is one byte, and the parameter code data supports a plurality of bytes.

By the above identification, function code data and parameter code data composed of bit data 0 and 1 can be obtained. Then, the electronic detonator judges whether the communication waveform is abnormal according to the writing clock frequency of the communication waveform, specifically: when the writing clock frequency of the communication waveform exceeds the set range, determining that the communication waveform is abnormal, otherwise, determining that the communication waveform is not abnormal. The setting range can be determined according to actual conditions.
