[0002] In the blasting process of electronic detonators, there is a process of charging all detonators in the network. When the initiation capacitor of all electronic detonators is fully charged, the command is waited for initiation.

[0003] At present, the industry generally uses fixed time charging or dynamically changes the charging time according to the number of electronic detonators in the network. This method is simple, but the efficiency is not high, and it cannot determine the completion of charging in time, resulting in a long waiting time in the operation process. At the same time, it does not consider the influence of the impedance of the network environment at that time on the charging time. SUMMARY

[0004] The main purpose of the present application is to provide an electronic detonator charging monitoring method, device and storage medium, which can determine whether the initiation capacitor of the electronic detonator is fully charged in real time at the fastest speed, without using fixed time to wait, improving the efficiency in the operation process, and adapting to various network environments.

[0005] To achieve the above purpose, the present application provides an electronic detonator charging monitoring method, which comprises the following steps:

[0006] Before charging, the current voltage of the electronic detonator is raised to the charging voltage, and the current value under the charging voltage condition is obtained;

[0007] The current threshold is calculated based on the current value under the charging voltage condition;

[0008] After starting charging, the charging current of the electronic detonator is continuously detected;

[0009] If the charging current is less than the current threshold for a specified number of times in succession, it is determined that the charging is completed.

[0010] The step of raising the current voltage of the electronic detonator to the charging voltage before charging and obtaining the current value under the charging voltage condition comprises:

[0011] The communication voltage before charging of the electronic detonator is obtained;

[0012] The current voltage of the electronic detonator is raised from the communication voltage to the charging voltage, and a first preset time is waited;

[0013] A current acquisition instruction is sent to the initiation card connected with the electronic detonator;

[0014] acquire a preset number of current values under the current charging voltage condition through the detonation card;

[0015] calculate an average current value of the preset number of current values.

[0016] The step of calculating the current threshold value based on the current values under the charging voltage condition comprises:

[0017] The current threshold value is calculated by increasing a preset proportion based on the average current value.

[0018] The step of continuously detecting the charging current of the electronic detonator after starting charging further comprises:

[0019] The charging instruction is started after the current voltage of the electronic detonator is reduced to the communication voltage.

[0020] The step of continuously detecting the charging current of the electronic detonator after starting charging comprises:

[0021] The starting charging time is recorded after starting charging.

[0022] The charging current of the electronic detonator is continuously detected after waiting for a second preset time.

[0023] The step of calculating the current threshold value based on the current values under the charging voltage condition further comprises:

[0024] The longest charging time required for the electronic detonator to complete charging is calculated.

[0025] The method further comprises:

[0026] If the charging current is not less than the current threshold value for a continuous specified number of times, the electronic detonator is charged according to the recorded starting charging time and the current charging time, and the longest charging time, or

[0027] If the charging current is not less than the current threshold value through current detection and the charging time exceeds the longest charging time, it is determined that charging is complete.

[0028] The step of determining that charging is complete if the charging current is less than the current threshold value for a continuous specified number of times comprises:

[0029] The charging time is increased by a third preset time after the initiation capacitor of the electronic detonator is fully charged through current detection.

[0030] Optionally, the first preset time is 2 seconds, the second preset time is 100 ms, the preset ratio is 10%, and the preset number of times is 10.

[0031] The application further provides an electronic detonator charging monitoring device, which comprises a memory and a processor, and the memory stores a computer program which is executed by the processor to realize the electronic detonator charging monitoring method.

[0032] The application further provides a computer storage medium, which stores a computer program which is executed by a processor to realize the electronic detonator charging monitoring method.

[0033] The application scheme judges whether the initiation capacitors of the electronic detonators in the network are fully charged by monitoring the charging current during the charging process, wherein a reference current before charging is dynamically obtained according to an existing networking environment, the voltage is raised to the charging voltage before charging, but no charging is performed, a current threshold is obtained, and the current size is continuously detected; when the charging current is less than the current threshold for a continuous specified number of times, it is considered that the charging is completed. Thus, whether the capacitors are fully charged can be judged in real time at the fastest speed without using a fixed time to wait. The efficiency in the operation process is improved; meanwhile, the dynamic current calculation method is used to adapt to various networking environments by considering the on-site environment of networking. For example, 500 electronic detonators are charged for 90 seconds to complete the charging, and if 120 seconds are set to wait, the operator needs to wait for 30 seconds more. Using the current monitoring method, the charging completion can be detected in 90 seconds in time, and the waiting time of the operator is reduced. Compared with the prior art, the application scheme considers the impedance under the current networking environment, can accurately judge whether the capacitors are fully charged in time, improves the efficiency compared with using a fixed time to charge, reduces the waiting time of the workers, and saves the cost.

[0036] It should be understood that the specific embodiments described herein are only used to explain the application, and are not used to limit the application.

[0037] REFERENCE Figure 1 The application provides an electronic detonator charging monitoring method, which comprises the following steps:

[0038] Step S1, before charging, the current voltage of the electronic detonator is raised to the charging voltage, and the current value under the charging voltage is obtained;

[0039] Specifically, first, the communication voltage of the electronic detonator before charging is obtained;

[0040] The current voltage of the electronic detonator is raised to the charging voltage from the communication voltage, and a first preset time is waited;

[0041] The electronic detonator is connected to the initiation card to send a current acquisition instruction;

[0042] The preset number of current values under the charging voltage is obtained through the initiation card;

[0043] The average current value of the preset number of current values is calculated.

[0044] Step S2, the current threshold is calculated based on the current value under the charging voltage;

[0045] Based on the average current value, a preset proportion is added to calculate the current threshold.

[0046] Step S3, after starting charging, the charging current of the electronic detonator is continuously detected;

[0047] Step S4, if the charging current is less than the current threshold for a specified number of times, it is determined that the charging is completed.

[0048] Wherein, before the step of continuously detecting the charging current of the electronic detonator after starting charging, it further comprises:

[0049] After the current voltage of the electronic detonator is lowered to the communication voltage, the charging instruction is started.

[0050] Wherein, the step of continuously detecting the charging current of the electronic detonator after starting charging comprises:

[0051] After starting charging, the start charging time is recorded;

[0052] After waiting for a second preset time, the charging current of the electronic detonator is continuously detected.

[0053] Wherein, after the step of calculating the current threshold based on the current value under the charging voltage, it further comprises:

[0054] The longest charging time required for the electronic detonator to complete charging is calculated;

[0055] After the step of continuously detecting the charging current of the electronic detonator after starting charging, the method further comprises:

[0056] If the charging current size is not less than the current threshold value for a continuous specified number of times, the electronic detonator is charged according to the recorded starting charging time and the current charging time, or if the charging current size is not less than the current threshold value through current detection and the charging time exceeds the longest charging time, it is judged that the charging is completed.

[0057] The step of determining that the charging is completed if the charging current size is less than the current threshold value for a continuous specified number of times comprises:

[0058] After the initiation capacitor of the electronic detonator is fully charged through current detection, a third preset charging time is added.

[0059] Optionally, the first preset time is 2 seconds, the second preset time is 100 ms, the preset ratio is 10%, and the preset number of times is 10.

[0060] The scheme of the present application determines whether the initiation capacitor of the electronic detonator in the network is fully charged by monitoring the charging current during the charging process. According to the existing networking environment, a reference current before charging is dynamically obtained, the voltage is raised to the charging voltage before charging, but no charging is performed, a current threshold value is obtained, and the current size is continuously detected. When the charging current is less than the current threshold value for a continuous specified number of times, it is considered that the charging is completed. Thus, the capacitor can be determined whether it is fully charged in the fastest speed in real time without using a fixed time to wait. The efficiency in the operation process is improved. At the same time, the on-site environment of networking is considered, and a dynamic current calculation method is used to adapt to various networking environments. For example, 500 electronic detonators are charged for 90 seconds to complete the charging, and we set to wait for 120 seconds, which means that the operator needs to wait for 30 seconds more. Using the current monitoring method, the charging can be detected to be completed in 90 seconds in time, reducing the waiting time of the operator. Compared with the prior art, the scheme of the present application considers the impedance in the present networking environment, can accurately determine whether the capacitor is fully charged in time, improves the efficiency compared with using a fixed time to charge, reduces the waiting time of the operator, and saves the cost.

[0061] The following will be combined Figure 2 The scheme of the present application will be described in detail:

[0062] As shown in the figure, the specific method for using current detection to judge the charging result of the electronic detonator is as follows: Figure 2

[0063] First, the preconditions for initiation are completed, and the charging process is entered:

[0064] ​Wherein, the front initiation precondition and preparation process can be processed by each electronic detonator chip manufacturer according to the operation steps of the detonator.

[0065] Then, the bus is boosted to the charging voltage: VCharge:

[0066] That is, the current voltage of the electronic detonator is raised from the communication voltage to the initiation capacitor charging voltage of the electronic detonator. Cooperate with the following steps, mainly to dynamically obtain the stable current value of the entire site environment at the charging voltage.

[0067] Then, wait for 2 seconds to stabilize the current on the bus:

[0068] Mainly to stabilize the bus current under the condition of charging voltage. This 2 seconds can be adjusted according to different schemes.

[0069] Then, get the current instruction from the initiation card, which can be initiated 10 times, and then calculate the average value of the current: CA0: This is mainly to obtain the current value under the condition of charging voltage.

[0070] Then, calculate the full charge current threshold: CThres = CA0 * 1.1:

[0071] Increase 10% on the basis of the average current value calculated above, which is used to judge whether the charging is full after opening the charging. If the continuous specified number of times is less than this value, it is considered that the charging is full and the current has returned to below the current threshold. Here, 10% can also be adjusted according to different electronic detonator schemes.

[0072] Among them, calculate the longest charging time required: CTimeMax = networked detonator number * single detonator charging longest time:

[0073] Here, according to the number of networked detonators and the charging time of the single detonator at the farthest distance, the longest time required for charging in the current network can be calculated to solve the problem when the current does not decrease, that is, to charge for the longest time.

[0074] Then, the bus is lowered to the communication voltage: VComm, and the charging instruction is sent to start charging:

[0075] Lower the voltage to the communication voltage and send the charging instruction. This can be determined by different chips whether it is needed.

[0076] After the charging starts, record the start charging time: CStartTime:

[0077] Record the time of starting charging, when no end is detected by current detection, also get how long the battery is charged by the start time and the current time, if it is greater than the previous calculated CTimeMax, it is judged as the end of charging.

[0078] Then, wait for 100 ms, the following flow is a loop of detecting bus current, when the total timeout time is greater than CTimeMax, it will end, another is when the charging current falls back to the current before charging, and the current of 10 consecutive detections is less than the full charging current threshold CThres, it is considered that the charging is completed. The 10 consecutive times here can be adjusted according to different electronic detonator schemes.

[0079] Then, wait for 3 seconds: this is to increase the charging time by 3 seconds after detecting that the charging is full by current detection, in order to ensure that the charging is completed. Here, the time can be adjusted or not needed according to different electronic detonator schemes.

[0080] Compared with the prior art, the scheme of the present application dynamically obtains the reference current before charging according to the existing networking environment, raises the voltage to the charging voltage before charging, but does not charge, obtains a current threshold, and then continuously detects the current size, when the current size is less than the threshold for a specified number of times, it is considered that the charging is completed. This method takes into account the impedance under the networking environment, and can accurately judge when the battery is full. Compared with using a fixed time, the efficiency is improved, the worker waiting time is reduced, and the cost is saved.

[0081] The present application also provides an electronic detonator charging monitoring device, the device includes a memory and a processor, the memory stores a computer program, the computer program is executed by the processor to realize the electronic detonator charging monitoring method as described above.

[0082] The present application also provides a computer storage medium, the computer storage medium stores a computer program, the computer program is executed by the processor to realize the electronic detonator charging monitoring method as described above.
