The existing electronic detonator data reading scheme is realized by reading one byte or continuously reading a plurality of bytes. When only one bit of data is needed, the entire byte has to be read out as well. And when the data is read each time, the data of all the electronic detonators in the same network can be read. However, in the application field of the electronic detonator, more than 500 electronic detonators with power generation are often connected to the same parallel network at the same time, and if it takes 100ms to read the data of one electronic detonator, it takes 50s to complete the data reading for the network with 500 electronic detonators with power generation. Data reading takes too long, seriously degrading the user experience. When the data reading is needed to judge that some electronic detonators in the network are abnormal, the data reading of all the electronic detonators may need to be repeated for many times, so that the problem cause cannot be found quickly, the reading result is waited for a long time, and the site construction efficiency is seriously influenced. Particularly, after the electronic detonator is charged, the electric quantity of the capacitor of the electronic detonator is consumed by long-time data reading, the voltage of the capacitor is reduced below a safety value during detonation possibly, and the explosive head cannot be detonated, so that the phenomenon of refusal of a construction site occurs, and the refusal of the detonation causes potential safety hazards and cost of a user in the later period of cleaning the detonators which are not detonated.

Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the embodiments of the present invention are further described in detail below with reference to the accompanying drawings. The exemplary embodiments and descriptions of the present invention are provided to explain the present invention, but not to limit the present invention.
In the description of the present specification, the terms "comprising," "including," "having," "containing," and the like are used in an open-ended fashion, i.e., to mean including, but not limited to. Reference to the description of 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 application. In this specification, the schematic representations of the terms used above do not necessarily refer to the same embodiment or example. 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 for illustrative purposes to illustrate the implementation of the present application, and the sequence of steps is not limited and can be adjusted as needed.
Fig. 1 is a flowchart of a bit data reading method of an electronic detonator in an embodiment of the present invention, and 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 the electronic detonators by detecting the received current signals, wherein the current signals are the current signals corresponding to the fed back bit data according to the initial reading network serial number and the bit data address after the electronic detonators receive the bit data reading instruction.
In summary, in the method provided in the embodiment of the present invention, first, the network serial number of each electronic detonator is configured, and the network serial number is not stored in the electronic detonator, which is shorter than reading the UID of the electronic detonator stored in advance, thereby saving the bit data reading time; secondly, the reading parameters sent to the electronic detonators comprise initial reading network serial numbers, so that the electronic detonators judge whether to read bit data or not according to the initial reading network serial numbers and the network serial numbers of the electronic detonators, namely, the reading of the bit data of a part of the electronic detonators in the plurality of electronic detonators is supported, and the flexible reading requirement 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 specific implementation, the method described in fig. 1 is implemented by using an initiator, where the initiator communicates with a plurality of electronic detonators, and typically the electronic detonators are connected to the same parallel network, and when the initiator is configured, the network serial number of each electronic detonator is encoded in a non-repeating sequence, 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 initiator acquires the UID code of each electronic detonator, the initiator forms a network serial number list according to the corresponding relation between the UID code of each electronic detonator and the network serial numbers, the network serial number list is stored in a memory of the initiator, and when data of a certain electronic detonator needs to be read, the corresponding network serial number can be found from the network serial number list. Then, the initiator 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 a new network serial number can be received again after the electronic detonator is powered on, compared with the method of using the pre-stored UID code or other MAC address codes of the electronic detonator, the method has the advantages that: firstly, the network serial number is generally expressed by natural numbers, the data volume is small, and the sending efficiency is high; secondly, if the UID code or other MAC address codes of the electronic detonator stored in advance have problems and need to be updated, the situation of repeatedly encoding the electronic detonator may exist, and in order to avoid repeated encoding, the UID codes or other MAC address codes of all the electronic detonators need to be traversed, so that the time consumption is long; and 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 detonator needs to be read, the initiator sends a bit data reading instruction and reading parameters to the electronic detonators, wherein the reading parameters comprise an initial reading network serial number and a bit data address, fig. 2 is a schematic diagram of a sending waveform of the initiator and a feedback waveform of the electronic detonator 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. The method also comprises a sending start bit before the actual sending of the time-bit data reading instruction, and is used for informing the electronic detonator that the electronic detonator is ready for receiving the reading instruction. After receiving the bit data reading instruction, the electronic detonator judges whether to read the bit data according to the initial reading network serial number and the network serial number of the electronic detonator, wherein the network serial number of the electronic detonator is previously received, for example, 500 electronic detonators are received, 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 20-500; and when the judgment result is reading bit data, 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 detonator recognizes the bit data of the electronic detonator with the network serial number of 20 to 500 by detecting the received current signal. In addition, except that the initial reading 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; and when the bit data address is 2, reading the value of the bit data with the address of 2 in the electronic detonator register. The visible bit data address can be modified according to the application field condition, and different bit data can be flexibly and repeatedly read for many times.
In a specific implementation, the reading parameters sent by the initiator may further include a network serial number, which is 1,2,3, … …, and 500 for example, the network serial numbers of 500 electronic detonators are respectively. The network serial number of the initial reading is 20, and the network serial number of the final reading is 50, so that only the electronic detonator with the network serial number of 20-50 is used as a feedback current signal, and the requirement of reading the bit data is met more flexibly.
In one embodiment, identifying bit data for a plurality of electronic detonators by detecting a received current signal comprises:
sending a set number of square waves 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 the received current signal fed back by the electronic detonator is a set current value, the duty ratio of the square wave corresponding to the electronic detonator is adjusted to a first proportion; when the received current signal fed back by the electronic detonator is zero, the duty ratio of the square wave corresponding to the electronic detonator is adjusted to a second proportion;
and identifying 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 a set number of square waves to the plurality of electronic detonators, the set number is determined according to the total number of the electronic detonators and the initial reading network serial number, for example, if there are 500 electronic detonators, and the network serial numbers are respectively from 1 to 500. When the electronic detonators with the network serial numbers of 21-500 are required to be read, the initial network serial number of 21 is determined to be read, the set number of 480 is 480, and 480 square waves are sent. If 500 electronic detonators are required 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, the network serial number is initially read to be 500, 1 square wave is sent, the current signal fed back by the electronic detonator is received at any time after the square wave is sent, wherein the set current value can be determined according to the actual situation and can be the set current value of the set time length, for example, the set time length can be 200us, and the set current value can be 20mA, then the bit data of the electronic detonator is identified, and for each electronic detonator, when the received current signal fed back by the electronic detonator is the set current value, the duty ratio of the square wave corresponding to the electronic detonator is adjusted to be a first proportion; when the received current signal fed back by the electronic detonator is zero, the duty ratio of the square wave corresponding to the electronic detonator is adjusted to a second proportion, wherein the first proportion and the second proportion can be determined according to actual conditions, such as 40% and 60% of equivalent values, 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 (the initial electronic detonator in fig. 3) corresponding to the initial reading network serial number is 0, and then the duty ratio of the square wave is adjusted to 60%; the current signal fed back by the electronic detonator (the second electronic detonator in fig. 3) corresponding to the next network serial number of the read network serial numbers is a set current value (for example, 20mA) with the duration of 200us, then the square wave duty ratio is adjusted to 40%, and subsequently bit data of a plurality of electronic detonators can be identified 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 includes: and before the set number of square waves are sent to the plurality of electronic detonators, sending a transceiving converter signal to the plurality of electronic detonators. The receiving and transmitting converter signal is used for smoothly receiving the current signal fed back by the electronic detonator and informing the electronic detonator to prepare data at the moment, so that the sufficient response time is given to the electronic detonator, 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 bit data reading quantity, and when the judgment result is the reading bit data, the electronic detonator reads the bit data of the electronic detonator according to the bit data address and the bit data reading quantity and feeds back a current signal corresponding to the bit data of the electronic detonator. For example, if the bit data address is 1 and the bit data reading number is 2, the bit data with address 1 in the register of the electronic detonator and the bit data with 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, so that the communication speed is greatly improved.
In the embodiment of the present invention, the electronic detonator is specifically used for: if the initial read network serial number is not greater than the network serial number of the electronic detonator, determining the judgment result as read bit data; and if the initial read network serial number is greater than the network serial number of the electronic detonator, determining that the judgment result is the data which is not read. For example, if the network serial number of the initial read network is 20 and the network serial number of the current electronic detonator is 19, the current electronic detonator does not read the bit data. The electronic detonators can read the bit data of a part of the electronic detonators in the plurality of electronic detonators through the judgment, and the flexible reading requirement is met.
In an embodiment of the present invention, the electronic detonator is further specifically configured to: when the bit data read from the electronic detonator according to the bit data address is 1, the feedback current signal is a set current value, otherwise, the feedback current signal is zero. After the initiator sends a set number of square waves to a plurality of electronic detonators, each electronic detonator identifies the square waves and counts the square waves, and the counting method comprises the following steps: the electronic detonator detects and accumulates the edge jump of the bus, and the two edge jumps are regarded as a finished square wave.
For each electronic detonator, if the sum of the currently counted bit number and the network serial number is equal to the network serial number of the electronic detonator, feeding back the bit data cached by the electronic detonator, specifically comprising the following steps: when the bit data read from the electronic detonator according to the bit data address is 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 a current signal, and as shown in fig. 3, the set time length can be fed back for 200 us.
