[0038] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Apparently, the described embodiments are some but not all of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0039] An electronic detonator, also known as a digital electronic detonator, digital detonator, or industrial digital electronic detonator, is an electric detonator that uses an electronic control module to control the initiation process. Traditional detonators rely on a simple resistance wire to be energized to ignite the primer for detonation, while the design of an electronic detonator and its initiation system introduces a dedicated software, and its firing system is detectable. To ensure the normal operation of the electronic detonator, it is necessary to use an electronic detonator testing instrument to test it.

[0041] S11, the main control sends a hole position calibration instruction.

[0042] S12, the test board receives the main control instruction.

[0043] S13, read the hole position data of the calibration board.

[0044] S14, upload the hole position data to the main control.

[0045] S15, the main control compares the hole position data.

[0047] S17, the calibration is completed.

[0048] S18, exit the calibration mode.

[0049] S19, enter the normal test mode.

[0050] Since almost all test instruments set the hole numbers of electronic detonators by burning and fixing the ID addresses for the multi-channel digital electronic detonator test board, when the electronic detonator test board needs to be replaced during assembly or maintenance, it is necessary to correspond to the test board of each hole position. Replacing and repairing the board is more troublesome. It is necessary to burn the fixed ID of the previous faulty board, and the operation process of the maintenance personnel is very cumbersome, greatly increasing the maintenance cost and time, and seriously delaying the production efficiency of the production line. Based on this, the embodiments of the present application provide a calibration system and method for a multi-channel digital electronic detonator test instrument to solve the above technical problems. The solution of the present application will be introduced below in conjunction with the accompanying drawings.

[0051] Figure 2 FIG. is a schematic structural diagram of a calibration system for a multi-channel digital electronic detonator test instrument provided by an embodiment of the present application, as Figure 2 shown, including a main control program board, a plurality of digital electronic detonator test boards, and a digital electronic detonator hole position calibration board, wherein:

[0052] The main control program board is used to send a calibration command to the first digital electronic detonator test board, and the first digital electronic detonator test board is any one of the plurality of digital electronic detonator test boards included in the multi-channel digital electronic detonator test instrument;

[0053] The first digital electronic detonator test board is used to read the first hole position data from the digital electronic detonator hole position calibration board according to the calibration command, and send the first hole position data to the main control program board;

[0054] The main control program board is further used to perform hole position calibration on the first digital electronic detonator test board according to the first hole position data.

[0055] In this embodiment, the main control program board writes a calibration test program inside the single-chip microcomputer, sets the electronic detonator hole position calibration data, and writes an independent hole position code for each hole position.

[0056] The digital electronic detonator test board reads the required hole position data of a single shot of the electronic detonator through the electronic detonator communication program.

[0057] The digital electronic detonator hole position calibration board simulates multi-channel electronic detonator hole positions, and each channel of electronic detonator hole position has a separate and unique hole position data.

[0058] After the main control program board sends a calibration command to the first electronic detonator test board, the first digital electronic detonator test board reads the first hole position data (independent hole position code) from the digital electronic detonator hole position calibration board, and transmits the first hole position data to the main control program board. After comparing the first hole position data with the internal hole position data of the main control program board, according to the comparison result, the main control program board performs hole position calibration on the first digital electronic detonator test board. Subsequently, the first digital electronic detonator test board saves the calibrated hole position data to complete the calibration process.

[0059] Specifically, the main control program board stores the hole position data of multiple digital electronic detonator test boards and the hole position identifiers corresponding to each hole position data; the specific functions of the main control program board are as follows:

[0060] Compare the first hole position data obtained from the first digital electronic detonator test board with the multiple hole position data inside itself, and determine the second hole position data that is the same as the first hole position data among the multiple hole position data;

[0061] Determine the hole position identifier corresponding to the second hole position data as the hole position identifier of the first digital electronic detonator test board.

[0062] Specifically, the main control program board is also specifically used for: sending a calibration command to the first digital electronic detonator test board according to the RS485 communication protocol (Introduction to RS485 communication protocol). Among them, RS-485 communication uses a balanced transmission and differential reception method to achieve communication, has extremely strong common-mode interference resistance ability, good transmission effect, and the highest data transmission rate of RS-485 is 10 Mbps;

[0063] Or, send a calibration command to the first digital electronic detonator test board according to the I2C (Inter-Integrated Circuit) communication protocol. Among them, I2C usually refers to the I2C bus, and the meaning of the I2C bus is "the specification or protocol for completing information exchange between integrated circuits or functional units". The I2C bus is a two-wire serial bus used to connect microcontrollers and their peripheral devices. It is a widely used bus standard in the field of microelectronics communication control. It is a special form of synchronous communication and has the advantages of few interface lines, simple control method, small device packaging form, and high communication rate.

[0064] Specifically, the first digital electronic detonator test board can read the first hole position data from the digital electronic detonator hole position calibration board according to the digital electronic detonator communication protocol.

[0065] The beneficial effects of a multi-channel digital electronic detonator test instrument calibration system provided by this application are as follows: First, each individual digital electronic detonator test board does not need to write fixed judgment hole position ID data; second, the detonator hole position calibration data collected by each digital electronic detonator test board is compared with the data of each hole position in the main control program, and according to the comparison result of the hole position data, the hole position setting is calibrated, so that the main control program board can accurately locate which hole position the electronic detonator test data is; the multi-channel digital electronic detonator test instrument calibration system and method provided by this application avoid the digital electronic detonator hole position errors caused by manual assembly during equipment assembly, and can well solve the equipment maintenance costs for the digital electronic detonator production line, including time and transportation costs, and greatly improve the efficiency in the production process of the production line.
