Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0025] Figure 1 is a schematic flow chart of a method according to an embodiment of the present invention. Figure 1 The execution subject can be a control system for blasting ignition. According to different requirements, the order of the steps in the flow chart can be changed, and some can be omitted.

[0026] like Figure 1 As shown, the method includes: S1. Collect blasting environment data using sensors and perform compliance verification on the blasting environment data. If the compliance verification is passed, the ignition execution authority is opened; if the compliance verification is not passed, the ignition execution authority is not opened; S2. Obtain target ignition mode; S3. Synchronously write the blasting environment data, the compliance verification results of the blasting environment data, and the target ignition mode into a shared memory, wherein the shared memory is respectively connected to the master controller and the slave controller for communication; S4. Confirm that the master controller has a fault, and the slave controller reads data from the shared memory and continues to execute the ignition program based on the read data.

[0027] In an embodiment of the present invention, based on step S1, a possible embodiment is given below to illustrate its specific implementation scheme in a non-limiting manner.

[0028] S101, receiving a detection signal from a detection knob, executing a self-check task based on the detection signal, and triggering collection and verification of blasting environment data based on the self-check task.

[0029] First, connect the detection knob to the input pin of the controller to ensure that the signal can be transmitted accurately.

[0030] The controller determines the position or state of the knob by reading the input signal of the detection knob.

[0031] Depending on the position or state of the knob, the controller performs the corresponding self-test task. For example, if the knob is in the "self-test" position, the controller will start a series of self-test procedures, including checking sensor connections, communication interface status, etc.

[0032] The controller is the controller currently processing the business, which is the master controller by default. If the master controller fails, it will switch to the slave controller.

[0033] S102. Collect blasting environment data using sensors, where the blasting environment data includes temperature, humidity, wind speed and direction, vibration intensity, and distance to surrounding objects; convert various safety requirements that should be followed in blasting operations in safety standards and operating procedures into verification rules in advance, and use the verification rules to perform compliance verification on the blasting environment data.

[0034] The controller reads blasting environment data such as temperature, humidity, wind speed and direction, vibration intensity, and distance to surrounding objects through sensor interfaces (such as I2C, SPI, etc.).

[0035] The collected data is preprocessed, such as filtering and denoising, to improve the accuracy of the data.

[0036] The pre-processed data is compared with the validation rules in the pre-set safety standards and operating procedures. These validation rules may include temperature range, humidity range, wind speed and direction limits, vibration intensity thresholds, and minimum distances from surrounding objects.

[0037] If the data meets the verification rules, the subsequent steps will be executed; if not, an alarm message will be generated and output to the display interface or an audible alarm will be issued.

[0038] S103, receiving an unlock signal from a software release button; if the ignition execution authority is open, releasing the short-circuit protection mode of the ignition circuit based on the unlock signal, and energizing the ignition circuit; if the ignition execution authority is not open, generating an abnormal prompt message, outputting the abnormal prompt message to a display interface, and energizing the ignition circuit after receiving an unlock confirmation signal.

[0039] Connect the software unlock button to the controller's input pin to ensure that the unlock signal can be received.

[0040] After receiving the unlock signal, the controller first checks whether the ignition execution permission is open. This can be achieved by reading a status flag or querying a permission database.

[0041] If the ignition execution authority is open, the controller will control a relay or switch circuit to release the short-circuit protection mode of the ignition circuit and energize the ignition circuit.

[0042] If the ignition execution permission is not open, the controller will generate an abnormal prompt message and output the information through the display interface. At the same time, the controller can also wait to receive the unlock confirmation signal. Once the confirmation signal is received and the permission is open, the controller will release the short-circuit protection and energize the ignition circuit.

[0043] In an embodiment of the present invention, based on step S2, a possible embodiment is given below to illustrate its specific implementation scheme in a non-limiting manner.

[0044] A potential signal of a control button is acquired, and the potential signal is converted into a target ignition mode, wherein the target ignition mode includes a four-way ignition mode or an eight-way ignition mode.

[0045] On the basis of the above embodiment, in order to further improve the service continuity and stability provided by the above embodiment, an implementable method is to share service data between the master controller and the slave controller, specifically including: A communication connection is established in advance between the master controller and the slave controller and the shared memory, wherein the shared memory is a non-volatile memory; a synchronous backup mechanism is configured, based on which the master controller or the slave controller marks the received data or the generated data with a timestamp and then synchronously backs it up to the shared memory.

[0046] The details of the communication connection between the master controller, slave controller and shared memory and the data synchronization and backup mechanism are as follows: In the blasting operation system, in order to ensure the real-time and reliability of data, the master controller and the slave controller need to establish an efficient and stable communication connection with the shared memory. This step is usually completed during system initialization, and the specific process includes: Hardware interface configuration: The master controller and slave controller are connected to the shared memory through specific hardware interfaces (such as serial communication interface, parallel bus interface or high-speed network interface). The selection of these interfaces should be based on comprehensive considerations of system performance requirements, cost budget and maintainability.

[0047] Communication protocol development: In order to ensure the accuracy and integrity of data during transmission, a set of protocols suitable for communication between the master controller, slave controller and shared memory needs to be developed. The protocol should clearly define key parameters such as data format, transmission rate, and verification method.

[0048] Connection test and verification: After establishing the communication connection, connection test and verification are required to ensure that the master controller and slave controller can correctly transmit data with the shared memory. This step usually includes operations such as sending test data, receiving and verifying data, etc.

[0049] In order to ensure data persistence and reliability, non-volatile memory should be given priority when selecting shared memory. Non-volatile memory has the characteristic that data will not be lost after power failure, so it is very suitable for storing critical data in blasting operations. Common non-volatile memory includes flash memory, hard disk drive (HDD) and solid state drive (SSD).

[0050] In the blasting operation system, data integrity and consistency are crucial. Therefore, a synchronous backup mechanism needs to be configured to ensure that the master controller or slave controller can back up the data to the shared memory in a timely manner after receiving or generating data. The specific process includes: Data timestamp: When data is received or generated, the system will mark it with a timestamp. The timestamp is used to record the time when the data is generated or received, so that the source and changes of the data can be accurately tracked in subsequent data processing and analysis.

[0051] Data synchronization backup: After receiving new data or generating new data, the master controller or slave controller will synchronize and back up the data together with the timestamp to the shared memory. This step is usually achieved by writing a special backup program, which will check the data changes in the master controller or slave controller regularly or in real time, and back up the changed data to the shared memory.

[0052] Backup data verification: In order to ensure the accuracy and completeness of the backup data, the system will also verify the backup data. The verification process usually includes data integrity verification, data consistency check and other operations. If there is a problem with the backup data, the system will promptly issue an alarm message and prompt the operator to take appropriate measures.

[0053] In summary, by pre-establishing the communication connection between the master controller and the slave controller and the shared memory, selecting the non-volatile memory as the shared memory, and configuring the synchronous backup mechanism, it can be ensured that the data in the blasting operation system always maintains integrity and consistency during transmission, storage, and processing, thereby further improving the safety and reliability of the system.

[0054] In an embodiment of the present invention, based on step S4, a possible embodiment is given below to illustrate its specific implementation scheme in a non-limiting manner.

[0055] The details of the heartbeat signal detection between the slave controller and the master controller, reading the shared memory data from the slave controller, and sending the restart command are as follows: To ensure the stability and reliability of the system, the slave controller and the master controller will periodically send heartbeat signals to each other. These heartbeat signals are real-time feedback of the health of the system and are used to monitor the operating status of the controller. The specific process includes: Heartbeat signal transmission: The master controller and the slave controller will send heartbeat signals to each other at preset time intervals. These signals are usually sent in the form of data packets, containing key information such as the sender's identification and timestamp.

[0056] Heartbeat signal reception and response: After receiving the heartbeat signal from the other party, the receiver will respond immediately. If the receiver does not receive the heartbeat signal from the other party within a set period (such as a few seconds or minutes), the fault detection mechanism will be triggered.

[0057] Fault confirmation: If the slave controller does not receive the heartbeat signal from the master controller within the set period, it will confirm that the master controller has a fault or abnormality. At this time, the slave controller will immediately activate the emergency response mechanism to ensure the continuous operation and safety of the system.

[0058] After the slave controller confirms that the master controller has a fault, it immediately reads all previously stored relevant data from the shared memory. This data includes critical information such as blasting environment data, compliance verification results, and target ignition mode. The specific process includes: Data reading: The slave controller will read the data stored in the shared memory through a stable communication connection established with the shared memory. This data has been written to the shared memory by the master controller and has undergone strict compliance verification.

[0059] Data verification: After reading data from the controller, it will verify the data to ensure the integrity and consistency of the data. The verification process may include data integrity verification, consistency check and other operations.

[0060] Ignition program execution: After ensuring that the data is correct, the slave controller will continue to execute the ignition program based on this data. It will accurately control the ignition process according to the parameter settings in the target ignition mode (such as ignition sequence, ignition intensity, delay setting, etc.) to achieve the best blasting effect and safety.

[0061] After the slave controller successfully takes over the work of the master controller and continues to execute the ignition program, it will also try to send a restart command to the master controller. This step is to try to restore the normal operation of the master controller to reduce the system downtime caused by controller failure. The specific process includes: Restart instruction sending: The slave controller will send a restart instruction to the master controller. The instruction usually contains key information such as the restart command and timestamp to ensure that the master controller can correctly perform the restart operation after receiving the instruction.

[0062] Restart status monitoring: After the slave controller sends a restart command, it will continue to monitor the operating status of the master controller. If the master controller successfully restarts and resumes normal operation after receiving the command, the slave controller will re-establish communication with the master controller and resume the previous cooperation relationship.

[0063] Fault handling and recording: If the master controller still cannot resume normal operation after receiving the restart command, the slave controller will continue to execute the current ignition program and record the fault information for subsequent analysis and processing. At the same time, the system will also issue an alarm message to prompt the operator to perform corresponding fault detection and repair work.

[0064] In summary, by sending heartbeat signals between the slave controller and the master controller, the slave controller reading data from the shared memory and continuing to execute the ignition program, and sending restart instructions to the master controller, the system can ensure that it can continue to maintain stable operation and safety performance when the master controller fails. These measures not only improve the reliability and stability of the system, but also reduce the potential safety risks caused by controller failures.
