Background
At present, the electronic detonator data reading scheme is realized in a mode of reading one byte or continuously reading a plurality of bytes. When only one bit of data is required, the entire byte has to be read out. And each time the data is read, the data of all the electronic detonators in the same network are read out. However, in the application site of the electronic detonator, there are often cases that more than 500 electronic detonators are simultaneously connected to the same parallel network, and if it takes 100ms to read the data of one electronic detonator, it takes 50s for the network with 500 electronic detonators to complete the data reading. The data reading takes too long, severely degrading the user experience. When the abnormality of some electronic detonators in the network is judged by means of data reading, the data reading of all the electronic detonators may need to be repeated for many times, so that the problem cause cannot be found rapidly, long time is consumed for waiting for the reading result, and the site construction efficiency is seriously affected.

The exemplary embodiments of the present invention and their descriptions herein are for the purpose of explaining the present invention, but are not to be construed as limiting the invention.
In the description of the present specification, the terms "comprising," "including," "having," "containing," and the like are open-ended terms, meaning including, but not limited to. Reference to the terms "one embodiment," "a particular embodiment," "some embodiments," "for example," etc., means that a particular feature, structure, or characteristic described in connection with the embodiment or example is included in at least one embodiment or example of the present application. In this specification, schematic representations of the above terms do not necessarily refer to the same embodiments or examples. Furthermore, the particular features, structures, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples. The sequence of steps involved in the embodiments is used to schematically illustrate the practice of the present application, and is not limited thereto and may be appropriately adjusted as desired.
Fig. 1 is a flowchart of a bit data reading method of an electronic detonator according to an embodiment of the invention, as shown in fig. 1, the method includes:
102, sending a bit data reading instruction and reading parameters to a plurality of electronic detonators, wherein the reading parameters comprise an initial reading network serial number and a bit data address;
and 103, identifying bit data of a plurality of electronic detonators by detecting received current signals, wherein the current signals are current signals corresponding to the fed back bit data according to the initial reading network serial number and the bit data address after the plurality of electronic detonators receive the bit data reading instruction.
In summary, in the method provided by the embodiment of the invention, firstly, the network serial number of each electronic detonator is configured, and is not stored in the electronic detonator, so that compared with the method for reading the UID of the prestored electronic detonator, the network serial number is shorter, and the bit data reading time can be saved; secondly, the reading parameters sent to the electronic detonators comprise an initial reading network sequence number, so that the electronic detonators judge whether to read bit data according to the initial reading network sequence number and the network sequence number of the electronic detonators, namely, the electronic detonators support to read bit data of a part of the electronic detonators in the plurality of electronic detonators, and the requirement of flexible reading is met; finally, the reading parameters sent to the electronic detonator comprise the bit data address, so that the electronic detonator can feed back a current signal corresponding to the bit data address, accurate reading of the bit data is realized, and the efficiency of reading the bit data is greatly improved.
In a specific implementation, the method shown in fig. 1 is generally implemented by an initiator, where the initiator communicates with a plurality of electronic detonators, and typically, the plurality of electronic detonators are connected to the same parallel network, and when the initiator is configured, a network serial number of each electronic detonator adopts a non-repeated sequential coding manner, for example, when there are 500 electronic detonators, the network serial numbers are 1,2,3, … …, and 500 respectively. When the network serial numbers are configured, the exploder firstly acquires the UID code of each electronic detonator, the exploder forms a network serial number list according to the corresponding relation between the UID code of each electronic detonator and the network serial number, the network serial number list is stored in a memory of the exploder, and when the data of a certain power generation sub detonator need to be read, the corresponding network serial number can be found out from the network serial number list. Then, the detonator sends the network serial number of each electronic detonator to the corresponding electronic detonator, the electronic detonator receives the network serial number of the electronic detonator, the network serial number is not stored in a memory of the electronic detonator, the electronic detonator fails after power failure, and can receive a new network serial number again after the electronic detonator is powered up, compared with UID codes or other MAC address codes of the electronic detonator which are stored in advance, the method has the advantages that: firstly, the network serial number is generally expressed by a natural number, the data volume is small, and the transmission efficiency is high; secondly, if the pre-stored UID codes or other MAC address codes of the electronic detonators are in a problem and need to be updated, the situation of repeated coding of the electronic detonators may exist, and in order to avoid repeated coding, the UID codes or other MAC address codes of all the electronic detonators need to be traversed, so that the time consumption is long; finally, the network serial number stored in the electronic detonator fails after power failure, and the storage space of the electronic detonator is not occupied.
In specific implementation, when the bit data of the electronic detonators need to be read, the initiator sends a bit data reading instruction and a reading parameter to a plurality of electronic detonators, wherein the reading parameter comprises an initial reading network serial number and a bit data address, and fig. 2 is a schematic diagram of a sending waveform of the initiator and a feedback waveform of the electronic detonators in the embodiment of the invention, wherein the bit data reading instruction is 1 byte, the initial reading network serial number is 2 bytes, and the bit data address is 1 byte. Before the actual sending of the time bit data reading instruction, the method also comprises a sending start bit for informing the electronic detonator that the electronic detonator is ready to accept the reading instruction. After receiving a bit data reading instruction, the electronic detonator judges whether to read bit data according to an initial reading network serial number and the network serial numbers of the electronic detonators, wherein the network serial numbers of the electronic detonators are received before, for example, 500 electronic detonators are all received before, and the initial reading network serial number is 20, and the electronic detonator needing to read the bit data is the electronic detonator with the network serial number of 20 to 500; and when the judgment result is that the bit data is read, reading the bit data of the electronic detonator according to the bit data address, and feeding back a current signal corresponding to the bit data of the electronic detonator. The initiator identifies the bit data of the electronic detonator with the network serial number of 20 to 500 by detecting the received current signal. In addition, besides the initial read network serial number can be specified according to the actual situation, the bit data address can also be specified according to the actual situation, for example, the bit data address is 1, namely, the value of the bit data with the address of 1 in the electronic detonator register can be read; when the bit data address is 2, the value of the bit data with the address of 2 in the electronic detonator register can be read. The visible bit data address can be modified according to the application site condition, and the reading of different bit data can be flexibly repeated for a plurality of times.
In particular, the read parameters sent by the initiator may further include a termination read network number, for example, the network numbers of 500 electronic detonators are 1,2,3, … …,500, respectively. The initial reading network serial number is 20, the final reading network serial number is 50, and then only the electronic detonator with the network serial number of 20-50 is used as a feedback current signal, so that the requirement of bit data reading is met more flexibly.
In one embodiment, identifying bit data for a plurality of electronic detonators by detecting received current signals includes:
sending square waves with set number to a plurality of electronic detonators, wherein the set number is determined according to the initial reading network serial number;
for each electronic detonator, when a received current signal fed back by the electronic detonator is a set current value, adjusting a square wave duty ratio corresponding to the electronic detonator to be a first proportion; when the received current signal fed back by the electronic detonator is zero, the square wave duty ratio corresponding to the electronic detonator is adjusted to be a second proportion;
and identifying the bit data of each electronic detonator according to the square wave duty ratio corresponding to each electronic detonator.
In the above embodiment, the initiator sends square waves to the plurality of electronic detonators in a set number, which is determined according to the total number of electronic detonators, the initial reading network number, for example, if there are 500 electronic detonators, and the network number is from 1 to 500, respectively. When the electronic detonator with the network serial number of 21 to 500 is wanted to be read, the initial network serial number of 21 is determined, the set number is 480, namely 480 square waves are sent. If the 500 electronic detonators are to be read, the network serial number is initially read to be 1, and 500 square waves are sent. If the data of the last electronic detonator is to be read, starting to read the network serial number of 500, transmitting 1 square wave, and receiving current signals fed back by the electronic detonators at any time after the square wave is transmitted, wherein the set current value can be determined according to actual conditions and can be a set current value with set duration, for example, the set duration can be 200us, the set current value can be 20 mA), then starting to identify the bit data of the electronic detonators, and for each electronic detonator, when the received current signals fed back by the electronic detonators are the set current values, adjusting the square wave duty ratio corresponding to the electronic detonators to be a first proportion; when the received current signal fed back by the electronic detonator is zero, the square wave duty ratio corresponding to the electronic detonator is adjusted to a second proportion, wherein the first proportion and the second proportion can be determined according to practical situations, for example, the values of 40% and 60% can be equal, fig. 3 is another schematic diagram of the sending waveform of the initiator and the feedback waveform of the electronic detonator in the embodiment of the invention, in fig. 3, the current signal fed back by the electronic detonator corresponding to the initial reading network serial number (initial electronic detonator in fig. 3) is 0, and then the square wave duty ratio is adjusted to 60%; and (3) reading the current signal fed back by the electronic detonator corresponding to the next network serial number of the network serial number (the second electronic detonator in fig. 3) to be a set current value (for example, 20 mA) with the duration of 200us, then adjusting the square wave duty ratio to be 40%, and then identifying the bit data of a plurality of electronic detonators according to the square wave duty ratio corresponding to each electronic detonator, wherein the electronic detonator feedback bit data corresponding to the square wave with the duty ratio of 40% is 1, and the electronic detonator feedback bit data corresponding to the square wave with the duty ratio of 60% is 0. Additionally, in fig. 3, in an embodiment, the method further comprises: the transception-transducer signal is transmitted to the plurality of electronic detonators prior to transmitting the set number of square waves to the plurality of electronic detonators. The receiving-transmitting converter signal is used for successfully receiving the current signal fed back by the electronic detonator and notifying the electronic detonator to perform data preparation at the moment, so that enough response time of the electronic detonator is given, and the accuracy of the current signal fed back by the electronic detonator can be improved.
In the embodiment of the invention, the reading parameters can also comprise the reading quantity of the bit data, and when the electronic detonator is judged to read the bit data, the bit data of the electronic detonator is read according to the bit data address and the reading quantity of the bit data, and a current signal corresponding to the bit data of the electronic detonator is fed back. For example, the bit data address is 1 and the number of bit data reads is 2, so that the value of the bit data address 1 in the electronic detonator register and the value of the bit data address 2 in the register can be read. In the embodiment of the invention, the reading time of 100 electronic detonators can be controlled within 200ms, and the communication rate is greatly improved.
In the embodiment of the invention, the electronic detonator is specifically used for: if the initial reading network serial number is not greater than the network serial number of the electronic detonator, determining that the judgment result is reading bit data; if the initial reading network serial number is larger than the network serial number of the electronic detonator, determining that the judgment result is that the bit data is not read. For example, the initial read network number is 20, and the current electronic detonator network number is 19, then the current electronic detonator does not read the bit data. The electronic detonator can read bit data of a part of the electronic detonators in the plurality of electronic detonators through the judgment, and the requirement of flexible reading is met.
In the embodiment of the invention, the electronic detonator is also specifically used for: when the bit data of the electronic detonator is read according to the bit data address to be 1, the feedback current signal is a set current value, otherwise, the feedback current signal is zero. After the exploder sends the square waves with set quantity to the plurality of electronic detonators, each electronic detonator recognizes the square waves and counts the square waves, and the counting method comprises the following steps: the electronic detonator detects and accumulates bus edge transitions, and two edge transitions are considered as a finished square wave.
For each electronic detonator, if the currently counted bit number plus the network sequence number is equal to the network sequence number of the electronic detonator, feeding back the self-cached bit number specifically comprises: when the bit data of the electronic detonator is read according to the bit data address to be 1, the feedback current signal is a set current value, otherwise, the feedback current signal is zero. In addition, each electronic detonator can feed back a set time length when feeding back the current signal, and can feed back 200us as shown in fig. 3.
