Description

Technical Field

[0001] The present invention relates to the technical field of microwave source board control, and specifically to a control method and system for multiple microwave source boards. Background Art

[0002] A microwave source refers to a device that generates microwave energy. Different application scenarios require microwave energy with different frequencies and different powers. There are continuous wave sources and pulsed modulated wave sources; magnetrons or microwave transistors are used to generate microwave oscillations. The requirements for microwave sources are the stability of output power and frequency.

[0003] Generally, after a user installs a microwave source device driver on Windows, uses the LOmoduleDll.dll dynamic link library provided by the microwave source manufacturer, calls the PXI_FindDev() interface to search for the microwave source device, and executes LOModule_Init() to initialize the device, and finally uses the interfaces LOModule_SetFreq() and LOModule_SetPower() to set the parameters of the microwave source power and frequency. However, when there are multiple microwave source boards in the chassis, the user cannot specify the microwave source in the corresponding slot for operation at the application layer, resulting in a disordered operating state of the device.

[0047] The present invention will be further described below with reference to the drawings and specific embodiments, so that those skilled in the art can better understand the present invention and be able to implement it. However, the embodiments cited do not limit the present invention. Without conflict, the embodiments of the present invention and the technical features in the embodiments can be combined with each other.

[0048] The embodiment of the present invention provides a control method and system for multiple microwave source boards, which is used to solve the technical problem of how to control multiple microwave source boards.

[0049] Embodiment 1:

[0050] The control method for multiple microwave source boards of the present invention includes the following steps:

[0051] S100. Based on the specified slot number issued by the upper-layer software, open the corresponding microwave source board through the underlying library, and create a board card number based on the device identifier of the microwave source board. The board card number serves as the identifier of the microwave source board;

[0052] S200. Based on the specified slot number sent by the upper-layer software, search for the microwave source board corresponding to the specified slot number from the chassis through the underlying library, and return the device information of the chassis. The microwave source board corresponding to the specified slot number is used as the target board. The device information includes the number of devices and the device address;

[0053] S300. Call the device initialization interface of the target board itself through the underlying library, and perform device initialization on the target board through the device initialization interface, including parameter initialization of the resource address, device handle, and error information of the target board. The resource address is the device file path of the microwave source board, the device handle is the device operation parameter, and the error information is used for reporting errors and viewing error information;

[0054] S400. Create a hash item for the target board through the underlying library. The key value of the hash item is the board card number of the target board, and the value of the hash item is the device handle of the target board. Insert the hash item into the hash table configured in the underlying library, and return the board card number of the target board to the upper-layer software;

[0055] S500. Based on the specified slot number sent by the upper-layer software, search for the corresponding hash item through the underlying library, and obtain the corresponding device handle. Perform setting operations on the microwave source board corresponding to the specified slot number based on the device handle.

[0056] In this embodiment, the upper-layer software sends the specified slot number through the web interface and obtains the board card number of the corresponding microwave source board. The upper-layer software is Anaconda. In step S100, it is necessary to install the upper-layer software Anaconda, create a working environment, execute the command conda activate awg, and then jupyter notebook can open the application interface of the upper-layer Web.

[0057] The upper-layer interface is configured in the underlying library. The upper-layer interface is the upper-layer interface configured with the open_resource() function. The parameter slot in this function is the slot number corresponding to the microwave source board. Open the microwave source board corresponding to the specified slot number through the upper-layer interface. The microwave source board is used as the target board, and return the device identifier module_id of the target board. Create a corresponding board card number module_id based on the device identifier module_id.

[0058] Step S200 performs device search and returns the device information of the chassis. Specifically, the PXI_FindDev interface configured with the PXI_FindDev() function in the underlying library is used to search for the device (microwave source board). In the PXI_FindDev() function, the parameter LoIndex is an array of device numbers. Here, LoIndex[0] is 1, which is the device address on slot 1, and LoIndex[1] is 2, which is the device address on slot 2. The parameter dev_num is the number of devices, and the parameter g_strErrMsg is the error message.

[0059] The code for finding the device is as follows:

[0060] static int find_dev(void)

[0061] {

[0062] int dev_num = 0;

[0063] char list

[32] = "", tmp

[32] = "";

[0064] / / Find the device

[0065] ret = PXI_FindDev(LoIndex, &dev_num, g_strErrMsg);

[0066] DBG("ret = %d,g_strErrMsg :%s\n", ret, g_strErrMsg);

[0067] return dev_num;

[0068] }

[0069] Step S300 initializes the target board. Specifically, it calls the initDev interface of the Python driver through the underlying library and calls the DLL_PXI_initDev interface of the C library to perform the device initialization operation. During the initialization operation, the DLL_PXI_initDev interface calls the LOModule_Init interface configured with the LOModule_Init function to initialize the device. In the LOModule_Init function, the parameter DataFilePath is the resource address (the data file path bound to the device number. Taking device 1 as an example, it is PowCalData\1\LoCalData_14dB.txt at this time), the parameter index is the device number of the device to be initialized, the parameter LoHandle is the device control handle, and all subsequent operations on the device need to use this parameter. The parameter g_strErrMsg is the error message.

[0070] Step S400 inserts the target microwave source. Specifically, it uses the open-source uthash C code to dynamically create a hash table entry map_item using malloc, and sets the key of map_item to the board number module_id and the value of map_item to the device handle LoHandle of the board. Then, it uses the HASH_ADD_INT() interface configured with the HASH_ADD_INT() function to insert the newly created hash table entry map_item into map_table to complete the insertion of the microwave source device, and returns the device identifier module_id to the upper layer. map_table is configured in the underlying library.

[0071] The code for initializing the device and storing the device handle is as follows:

[0072] EXT_API int DLL_PXI_initDev(int nslot)

[0073] {

[0074] char dev_str[2]

[64] = { "\\PowCalData\\1\\LoCalData_14dB.txt","\\PowCalData\\2\\LoCalData_14dB.txt"};

[0075] if (index == 1 || index == 2)

[0076] {

[0077] strcat_s(CurrentDir, sizeof(CurrentDir),dev_str[index - 1]);

[0078] }

[0079] ret = LOModule_Init(DataFilePath, index,&LoHandle[path_index], g_strErrMsg);

[0080] module_id = ++map_count;

[0081] map_item->module_id = module_id;

[0082] map_item->fd = LoHandle[path_index];

[0083] HASH_ADD_INT(map_table, module_id, map_item);

[0084] }

[0085] Step S500 performs device setup operations. When the user needs to operate on a microwave source with a specified slot number, for example, to set the output frequency of the microwave source, only the corresponding slot number needs to be specified. The underlying library will first receive the slot number parameter passed in by the upper-layer software, convert this slot number into a key value corresponding to the board, use the HASH_FIND_INT interface to find the hash table entry map_item corresponding to this key value in the hash table map_table, and then the device handle LoHandle of this slot can be obtained; call the configured interface when the user needs to operate on a microwave source with a specified slot number. For example, to set the output frequency of the microwave source, only the corresponding slot number needs to be specified. The underlying code will first receive the slot number parameter passed in by the upper layer, convert this slot number into a key value corresponding to the board, use the HASH_FIND_INT interface to find the hash table entry map_item corresponding to this key value in the hash table map_table, and then the device handle LoHandle of this slot can be obtained; call the interface LOModule_SetFreq to set the output frequency. The parameter LoHandle is the device handle just obtained, the parameter dFreqMHz is the expected frequency size to be set, and the parameter g_strErrMsg is the error message function. Call the LOModule_SetFreq interface to set the output frequency. In the LOModule_SetFreq function, the parameter LoHandle is the device handle just obtained, the parameter dFreqMHz is the expected frequency size to be set, and the parameter g_strErrMsg is the error message.

[0086] The code for setting the output frequency is as follows:

[0087] EXT_API bool DLL_PXI_setFreq(int module_id, double dFreqMHz)

[0088] {

[0089] HASH_FIND_INT(map_table, &module_id, map_item);

[0090] / / Set the frequency, MHz

[0091] if (LOModule_SetFreq(map_item->fd, dFreqMHz, g_strErrMsg) < 0) {

[0092] ERR("%s\n", g_strErrMsg);

[0093] return false;

[0094] } else {

[0095] ERR("module_id %d not found.\n", module_id);

[0096] return false;

[0097] }

[0098] return true;

[0099] }

[0100] This step also involves output power setting. When it is necessary to set the output frequency of the microwave source, only the corresponding slot number needs to be specified, and the LOModule_SetPower interface configured with the LOModule_SetPower function is called for output power setting. In the LOModule_SetPower function, the parameter LoHandle is the device handle just obtained, the parameter dPower is the desired set power value, and the parameter g_strErrMsg is the error message.

[0101] The code for setting the output power is as follows:

[0102] EXT_API bool DLL_PXI_setPower(int module_id, float dPower)

[0103] {

[0104] module_id_file_descriptor_map_table *map_item;

[0105] HASH_FIND_INT(map_table,&module_id, map_item);

[0106] if (LOModule_SetPower(map_item->fd, dPower, g_strErrMsg)<0) {

[0107] ERR("%s\n", g_strErrMsg);

[0108] return false;

[0109] } else {

[0110] ERR("module_id %d not found.\n", module_id);

[0111] return false;

[0112] }

[0113] return true;

[0114] }

[0115] When switching the microwave sources of different slots, the underlying library calls the HASH_FIND_INT() interface and can return different hash table entries map_item through the board number module_id. When performing frequency or power setting operations on the microwave source again, the device handle has been successfully updated to the microwave source board to be controlled as expected, and thus the control of multiple microwave source boards can be successfully achieved.

[0116] As an improvement of this embodiment, before initializing the identification of the target board, the underlying library calls the check_device_exist() interface to detect whether the device address obtained in step S200 matches the content of the local device file; if the match is successful, the LOModule_Init interface is called for device initialization.

[0117] Embodiment 2:

[0118] The control system of the multi-microwave source board of the present invention controls the multi-microwave source board through the control method of the multi-microwave source board disclosed in Embodiment 1. The control system includes an upper-layer software and an underlying library. The upper-layer software is used to issue slot numbers, and the underlying library is configured with a device identification module, a device search module, a device matching module, a device initialization module, a device warehousing module, a device operation module, and a board switching module.

[0119] In this embodiment, the upper-layer software issues slot numbers through a web interface. Specifically, the upper-layer software is Anaconda. In step S100, it is necessary to install the upper-layer software Anaconda, create a working environment, execute the command conda activate awg, and then jupyter notebook can open the application interface of the upper-layer Web.

[0120] The device identification module is used to open the corresponding microwave source board based on the specified slot number issued by the upper-layer software, and create a board card number based on the device identification of the microwave source board. The board card number is used as the identification of the microwave source board. In this embodiment, the device identification module is configured with an upper-layer interface, which is an upper-layer interface configured with the open_resource() function. The parameter slot in this function is the slot number corresponding to the microwave source board. The microwave source board corresponding to the specified slot number is opened through the upper-layer interface. This microwave source board is used as the target board, and the device identification module_id of the target board is returned. A corresponding board card number module_id is created based on this device identification module_id.

[0121] The device search module is used to search for the microwave source board corresponding to the specified slot number from the chassis based on the specified slot number issued by the upper-layer software, and return the device information of the chassis. The microwave source board corresponding to the specified slot number is used as the target board. The device information includes the number of devices and the device address. In this embodiment, the device search module is configured with a PXI_FindDev interface. This PXI_FindDev interface is configured with a PXI_FindDev() function to search for devices (microwave source boards). In the PXI_FindDev() function, the parameter LoIndex is an array of device numbers. Here, LoIndex[0] is 1, which is the device address on slot 1; LoIndex[1] is 2, which is the device address on slot 2. The parameter dev_num is the number of devices, and the parameter g_strErrMsg is the error message.

[0122] The device matching module is used to match the target board based on the device address, and determine whether the device address of the target board obtained from the returned device information is consistent with the device address stored locally. The device matching module is configured with a check_device_exist() interface. The device matching module calls the check_device_exist() interface to detect whether the device address in the returned device information matches the content of the local device file. If the match is successful, device initialization is performed.

[0123] The device initialization module is used to call the device initialization interface of the target board, and perform device initialization on the target board through the device initialization interface, including parameter initialization of the resource address, device handle, and error information of the target board. The resource address is the device file path of the microwave source board, the device handle is the device operation parameter, and the error information is used to report errors and view error messages. In this embodiment, the device initialization module calls the initDev interface of the python driver and the DLL_PXI_initDev interface of the C library to perform device initialization operations. During the initialization process, the DLL_PXI_initDev interface calls the LOModule_Init interface configured with the LOModule_Init function to perform device initialization. In the LOModule_Init function, the parameter DataFilePath is the resource address (the data file path bound to the device number, taking device 1 as an example, it is PowCalData\1\LoCalData_14dB.txt at this time), the parameter index is the device number of the device to be initialized, the parameter LoHandle is the device control handle, and this parameter needs to be used for subsequent operations on the device. The parameter g_strErrMsg is the error information.

[0124] The device insertion module is used to create a hash item for the target board. The key value of the hash item is the board card number of the target board, and the value of the hash item is the device handle of the target board. The hash item is inserted into the hash table configured in the underlying library, and the board card number of the target board is returned to the upper-layer software. The device operation module is used to find the corresponding hash item through the underlying library based on the specified slot number sent by the upper-layer software, and obtain the corresponding device handle. Based on the device handle, device setting operations are performed on the microwave source board corresponding to the specified slot number. The device setting operations include output frequency setting and output power setting. In this embodiment, the device insertion module uses the open-source uthash C code to dynamically create a hash table item map_item using malloc, and sets the key of map_item to the board card number module_id and the value of map_item to the device handle LoHandle of the board card. Then, the newly created hash table item map_item is inserted into map_table using the HASH_ADD_INT() interface configured with the HASH_ADD_INT() function to complete the insertion of the microwave source device. And the device identifier module_id is returned to the upper layer. map_table is configured in the underlying library.

[0125] The device operation module is used to find the corresponding hash item through the underlying library based on the specified slot number sent by the upper-layer software, and obtain the corresponding device handle. Based on the device handle, device setting operations are performed on the microwave source board corresponding to the specified slot number. The device setting operations include output frequency setting and output power setting. In this embodiment, the device operation module is configured with the LOModule_SetFreq interface and the LOModule_SetPower interface. The LOModule_SetFreq interface is configured with the LOModule_SetFreq interface function. In the LOModule_SetFreq function, the parameter LoHandle is the device handle, the parameter dFreqMHz is the expected set frequency value, and the parameter g_strErrMsg is the error message. The LOModule_SetFreq interface is called to perform the output frequency setting. The LOModule_SetPower interface is configured with the LOModule_SetPower function. In the LOModule_SetPower function, the parameter LoHandle is the device handle, the parameter dPower is the expected set power value, and the parameter g_strErrMsg is the error message. The LOModule_SetPower interface is called to perform the output power setting.

[0126] The board card switching module is used to return different hash table entries based on the board card number to switch different microwave source boards for device setting operations. The board card switching module is configured with the HASH_FIND_INT() interface. When switching microwave sources in different slots, the board card switching module calls the HASH_FIND_INT() interface. Through the board card number module_id, different hash table entries map_item can be returned. When performing frequency or power setting operations on the microwave source again, at this time the device handle has been successfully updated to the desired controlled microwave source board, and thus the control of multiple microwave source boards can be successfully achieved.
