[0041] The present invention is further described in detail below in conjunction with the examples and specific implementation methods. However, this should not be understood as the scope of the above subject matter of the present invention being limited to the following examples, and all technologies realized based on the content of the present invention belong to the scope of the present invention.

[0042] In the description of the present invention, it is necessary to understand that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0043] like Figure 1As shown, the present invention provides an optimization method for a downhole setting control module, which specifically includes the following steps:

[0044] S1: Input the external communication signal into the first interface of the sealing control module through the first demodulation circuit, and input the communication signal into the second interface of the sealing control module through the second demodulation circuit; and input the external first motor signal into the third interface of the control module, and input the external second motor signal into the fourth interface of the control module.

[0045] In this embodiment, since there are many noises in the carrier signal on the single-core cable during the actual perforating operation, the carrier signal is not easy to collect after the motor is running; the main improvement design is to perform redundant backup on the key signals of the MCU, such as communication signals and motor signals.

[0046] In this embodiment, the demodulation circuit is an existing circuit, so it is not described in detail; the technical improvement is that the communication signal is input into the sealing control module through two demodulation circuits, which increases the reliability of signal acquisition.

[0047] In this embodiment, a simple cyclic priority decision algorithm is designed to realize the dynamic switching of communication signal and motor signal link. When making a decision, first find the highest priority in the decision queue and execute the corresponding service function. If the service is normal, the service result is obtained. Otherwise, the current priority is placed at the end of the queue, and the remaining priorities are incremented by 1, and the search and execution process is repeated. Through the cyclic priority decision algorithm, the reliability of communication is enhanced and the motor position information can be tracked.

[0048] Among them, the priority is the dual-channel communication interface as one group of priorities, and the dual-channel motor interface as another group of priorities; when the software of each group is started, channel 1 has the highest priority by default, but it will be switched during operation according to the actual situation of the control module; the input signal of the channel with the higher priority will be selected.

[0049] The control software designs a circular priority decision tree structure, which mainly includes priority, total number, port, and port number. Priority is the priority of the service object, total number refers to the total number of services, port refers to the port used by the object, and port number refers to the port number used by the object, such as the PB6 port used by the communication receiving interface 1.

[0050] In this embodiment, a communication service function interface int ComRcvData(RoundRobinArbiter*rra) is also designed, including a first interface and a second interface, which are used to realize the reception and parsing of single-core communication data. The return value is used to determine whether the communication port is working normally, and the communication service result data is stored in the global array gu8_ComBuf.

[0051] In this embodiment, a motor position information reading service interface int ReadMotorHall(RoundRobinArbiter*rra) is designed, including a third interface and a fourth interface, which are used to realize the collection of motor Hall signals. The return value is used to determine whether the motor hall collection port is working normally. The collected Hall number is stored in the global variable gu32_MotorHallSwitchCnt.

[0052] S2: When the setting control module is powered on, a power-on self-test is performed on the control interface, communication interface, motor interface and onboard peripheral interface respectively.

[0053] In this embodiment, the control interface includes a motor enable control interface, a motor direction control interface, a first communication sending interface, and a second communication sending interface; the communication interface includes a first communication receiving interface and a second communication receiving interface; the motor interface includes a first motor signal acquisition interface and a second motor signal acquisition interface; and the onboard peripheral interface includes a programmable resistor AD5245.

[0054] In this embodiment, the setting control module enters the application unit to perform initialization, and after the initialization is completed, the power-on self-test process is performed. The purpose of the power-on self-test is to ensure that the module is in the correct state. This solution uses hardware to add a multiplexer MAX396 to perform connection detection on the detection interface, and the signal is input to the detection interface. The detection interface defaults to a floating input.

[0055] Detection of the control interface: The control interface repeatedly outputs a 1Khz pulse signal 10 times to determine whether the control interface is normal;

[0056] Detection of the communication interface: configure the communication interface to output mode, and control the interface to simulate single-core communication to output a self-test pulse signal, so as to determine whether the communication interface is normal;

[0057] Detection of the motor interface: configure the detection interface to output mode, and control the detection interface to output 10 1Khz pulse signals to determine whether the motor interface is normal;

[0058] Detection of onboard peripheral interface: configure the detection interface to analog input mode, control the output of a first voltage (1.2V), and detect whether the voltage is within the threshold range (1.2±0.1v). If so, it means that the onboard peripheral interface is normal, otherwise it means that the onboard peripheral interface is abnormal.

[0059] like Figure 2 As shown in the figure, the power-on self-test process of the control interface is as follows:

[0060] The sealing control module enters the application unit to perform initialization (the self-test result is 0), and uses the control interface involved in the sealing module to initialize the control list (including I channels, each channel corresponds to a control interface), and switches to the i-th channel, 1≤i≤I; the detection flag (that is, a uchar type local variable in the self-test function) is initialized to 0, and the detection flag is inverted (that is, 0->1, 1->0 operations, the purpose is to allow the detection interface to switch the output high and low levels), the i-th channel outputs the flag state (the detection flag state is consistent, the detection flag is 1 when the output is high, and the detection flag is 0 when the output is low). Level), after a delay of T1 time (for example, 0.5s), the detection interface (the detection interface is the selector output of MAX396 directly connected to port PB0 on ​​the microcontroller) determines whether the input level is consistent with the flag state. If so, it loops and detects 10 times (if not 10 times, the detection flag is inverted), and then the self-test of the next control interface (i+1 channel) is performed; if not, the self-test of the i-th channel is marked as failed, and the self-test is looped and tested 10 times, and then the self-test of the next control interface (i+1 channel) is performed; it is determined whether to traverse the control list, if so, it ends, if not, it switches to the next channel (i+1 channel).

[0061] In this embodiment, if the first communication sending interface self-tests normally, the first communication sending interface is used; if the first communication sending interface self-test fails, the second communication sending interface is used to play a redundancy role and ensure that the module can work normally.

[0062] like Figure 3 As shown in the figure, the power-on self-test process of the communication interface is as follows:

[0063] Initialize the receiving list (including M channels, each channel corresponds to a receiving interface) with the receiving interface involved in the communication with the sealing module, and configure the detection interface as output; switch to the mth channel, 1≤m≤M; the mth channel sends a self-test command, and the detection port identifies whether the self-test command is received; if not, mark the mth channel self-test as failed, and then switch to the next channel (m+1th channel); if so, mark the mth channel self-test as successful, and switch to the next channel (m+1th channel); determine whether to traverse the receiving list, if so, end, if not, switch to the next channel (m+1th channel).

[0064] In this embodiment, if the first communication receiving interface self-checks normally, the first communication receiving interface is used; if the first communication receiving interface self-checks unsuccessfully, the second communication receiving interface is used, which plays a redundancy role and ensures that the module can work normally.

[0065] like Figure 4 As shown in the figure, the power-on self-test process of the motor interface is as follows:

[0066] Initialize the acquisition list with the motor signal (including J channels, each channel corresponds to an acquisition interface), and configure the detection interface as output; switch to the j-th channel, 1≤j≤J; initialize the detection flag to 0, and invert the detection flag, the j-th channel outputs the flag state, and after a delay of T2 time (for example, 0.5s), the acquisition interface determines whether the input level is consistent with the flag state. If so, loop the detection for 10 times (if not 10 times, invert the detection flag), and then perform self-test on the next acquisition interface (j+1-th channel); if not, mark the j-th channel self-test as failed, and loop the detection for 10 times, and then perform self-test on the next acquisition interface (j+1-th channel); determine whether to traverse the acquisition list, if so, end, if not, switch to the next channel (j+1-th channel).

[0067] In this embodiment, if the first motor signal acquisition interface self-tests normally, the first motor signal acquisition interface is used; if the first motor signal acquisition interface self-test fails, the second motor signal acquisition interface is used to play a redundancy role and ensure that the module can work normally.

[0068] like Figure 5 As shown in the figure, the power-on self-test process of the onboard peripherals is as follows:

[0069] Configure the detection interface as analog input, adjust the voltage (programmable resistor AD5245) to output 1.2V, and the detection interface determines whether the analog input is within the preset range (1.1V-1.3V); if so, mark the voltage output as successful; otherwise, mark the voltage output as failed; the detection is completed and the voltage output is reset.

[0070] S3: In order to protect the circuit board components, a potting process is performed before leaving the factory. Therefore, there is no reserved programming interface on the external interface of the sealing control module. When reprogramming or troubleshooting the module, the shell must be destroyed and the potting glue must be removed first, resulting in a waste of manpower, material resources and other resources, seriously affecting the progress, and there is a risk of damaging the module circuit components.

[0071] Based on this, an optimized solution for single-core upgrade was designed, including a guide unit and an application unit. The sealing control module can be programmed or reprogrammed through a single-core cable.

[0072] In this embodiment, when the setting control module passes the self-test, it first enters the boot unit (BootLoader), and enters the application unit (App) if no upgrade request is received within 1 second or the upgrade is completed.

[0073] The main control MCU used in the sealing control module is Stm8AF6268, the Flash space is 32Kbyte, and the boot unit and application unit are deployed in the Flash space. According to the size of the compiled program, the Flash space is allocated and designed. The allocation scheme is as follows: Figure 6 The boot unit occupies 10Kbytes of space, the application unit occupies 19Kbytes of space, the application information area occupies 1Kbytes of space, and the reserved area occupies 2Kbytes of space.

[0074] In this embodiment, the single-core upgrade process of the boot unit includes waiting for request, information aggregation, upgrade storage, upgrade verification and application jump, such as Figure 7 As shown, the specific steps include:

[0075] A-1: If Figure 8 As shown, after the power-on initialization is completed, the boot unit enters the waiting request, and starts a counter at the same time. During operation, it queries the counter in real time whether it exceeds the first time (the first time is 1s). If the upgrade request command frame sent by the ground system is received within the first time, the 3s counter is restarted, the request success reply is sent, and the information is summarized. If it exceeds the first time, the application jump is entered.

[0076] A-2: If Fig. 9 As shown, after entering the information summary, check in real time whether the counter exceeds the second time. If the upgrade information frame header data frame sent by the ground system is received within the second time, the counter is destroyed, and the received upgrade information is recorded, including the total data size, the total number of data packets and the upgrade start address. If the upgrade information is reasonable (the upgrade start address and the total data size meet the requirements of the application software area allocated by Flash), the expected packet number is set to 1, the amount of successfully received data is cleared, and the correct information response is sent to enter the upgrade storage; if the upgrade information is abnormal (the upgrade start address and the total data size do not meet the requirements of the application software area allocated by Flash), an abnormal information response is sent and the request is returned to the waiting time. If the second time is exceeded, the application jump is entered.

[0077] A-3: If Fig.10 As shown, after entering the upgrade storage, continue to wait for the upgrade data packet of the ground system; when receiving the upgrade data packet, determine whether the received packet number is consistent with the expected packet number, if not, send a storage failure response command; if so, store the data according to the upgrade starting address and packet number, the expected packet number is incremented by 1, the amount of successfully received data is increased by the current received data size, and then determine whether the received packet number is consistent with the total number of packets, if so, send a storage completion response command to enter the upgrade verification, if not, send a storage success response command.

[0078] A-4: If Fig.11As shown, after entering the upgrade verification, continue to wait for the verification command frame of the ground system. After receiving the verification command frame, determine whether the total data size and the amount of successfully received data are equal; if not, mark the number as wrong and directly send a verification failure response; if so, perform a crc32 check on the storage area of ​​the upgrade storage to determine whether the calculated value is equal to the verification information in the verification command. If so, send a verification success response and enter the application jump; if not, mark the verification value as wrong and send a verification failure response.

[0079] In this embodiment, after entering the application unit (i.e., application jump), the port, Flash, timer and other resources initialized by the boot unit are reset, and the jump code is executed to complete the software upgrade. The jump code is "asm("LDW X,SP"); asm("LD A,$FF"); asm("LD XL,A"); asm("LDW SP,X"); asm("JPF,$A800");".
