In the inertial measurement system, it is generally necessary to test the digital switch quantity of the inertial product in order to confirm the performance of the inertial product. Usually, different inertial products correspond to different switch quantity quantities, related hardware ports, communication protocols, etc. In addition, when the inertial product is working, there will be a certain sequence between the switch quantities or cross-mixing with other signals, which causes the inertial measurement system to require coordination between software and hardware engineers when docking with new inertial products in the early stage, which consumes a lot of time and energy.

The inertial measurement system performs targeted tests on each inertial product, and there are the following problems: 1. When the switch port or communication protocol of the same inertial product is changed, the inertial measurement system needs to be changed accordingly; 2. Different inertial products require the inertial measurement system to produce different test plans and test processes, resulting in a waste of resources in the production process.

[0025] The present invention will be further described below in conjunction with the accompanying drawings.

[0026] The digital switch quantity detection device of the inertial measurement system of the present invention is mainly composed of four parts: monitoring control display module, digital switch quantity analysis and combination module, configuration file module, and bottom hardware communication interface module. Figure 1 .

[0027] The monitoring control display module mainly realizes the switch quantity status, fault display and switch quantity control operation. The digital quantity information is designed in the form of digital lights, which can be displayed in bright or dark according to the switch quantity status, so that users can confirm the current switch quantity status. For the input switch quantity, only the current status needs to be displayed; for the output switch quantity, the status can be displayed, and the switch quantity can be turned on or off intuitively in the display interface. The content displayed by the monitoring control display module is consistent with the content in the configuration file management.

[0028] All switch quantity information is saved in the configuration file for management. Before starting the test, the switch quantity information in the configuration file is loaded into the computer memory for monitoring, control, display and switch quantity control, and also for the underlying hardware communication. The switch quantity information parameter configuration content is shown in Table 1. The switch quantity information parameter configuration file is loaded, analyzed, and interpreted and stored in the computer memory. Each switch quantity information is managed by a data structure and stored in the memory. All switch quantity information is saved in the system memory in the form of a linked list. The storage method in the memory is shown in Table 1. Figure 2 , Figure 3 When applied, the specified switch quantity information can be found through the unique identification number.

[0031] The underlying hardware communication interface module mainly encapsulates two different hardware driver interfaces for two types of switch quantities. Through the class and inheritance method, the module can adaptively match the corresponding hardware driver interface to control the digital switch quantity of the inertial product when applied. The underlying hardware communication interface module reads the digital switch quantity status of the inertial product in real time and passes the switch quantity status information to the digital switch quantity analysis combination module.

[0032] The main function of the digital switch quantity analysis combination module is to convert the content in the configuration file into information that can be used for monitoring, control and display by applying the information in the switch quantity chain table, and to convert the operation control information in the monitoring, control and display management into the underlying hardware communication interface information through the information in the switch quantity chain table. At the same time, it also converts the switch quantity status information read in real time by the underlying hardware communication module into information that can be used for monitoring, control and display. The main functions of the digital switch quantity analysis combination are shown in Figure 4 .

[0033] The digital switch quantity analysis and combination module converts the content in the configuration file into information that can be used for monitoring, control and display. It mainly traverses the switch quantity chain list and displays the names of all switch quantity information in the monitoring, control and display module. The unique identifier can quickly and effectively find relevant information in the chain list. The digital switch quantity analysis and combination module establishes a mutual connection between the information displayed in the monitoring, control and display module and the switch quantity information.

[0034] The operation control information in the monitoring control display module is transmitted to the digital switch quantity analysis combination module through message transmission. The digital switch quantity analysis combination module converts it into the underlying hardware communication information according to the digital quantity type, port / bit number and other information, so as to facilitate the underlying hardware communication interface module to control the inertial product.

[0035] The bottom hardware communication interface module reads the switch quantity status of the inertial product in real time and passes it to the digital switch quantity analysis combination module. The digital switch quantity analysis combination module first determines whether the switch quantity status has changed. If there is no change, no processing is performed. If there is a change, the port number / bit number and type are used to determine the unique identifier of the change, thereby notifying the monitoring control display module to update the interface display.

[0036] The present invention also provides a switch quantity detection working method. Figure 6 , the working process is divided into two parts: input switch quantity display and output switch quantity control.

[0037] 1. Input switch quantity display process: After the configuration file is loaded and the interface is initialized, the underlying hardware interface module reads the switch quantity status of the inertial product in real time and passes the switch quantity status to the switch quantity analysis and packaging module. The switch quantity analysis and packaging module determines whether the switch quantity status has changed. If the switch quantity status has not changed, no processing is performed. If the switch quantity status has changed, the changed switch quantity information is determined according to the switch quantity port number / bit number and switch quantity type, and the monitoring control display module is notified to update the interface information. The monitoring control display module changes the switch quantity status to make the indicator light corresponding to the switch quantity on or off. The whole process is repeated until the user stops the test.

[0038] 2. Output switch quantity control process: After the configuration file is loaded and the interface is initialized, the user selects a certain output switch quantity in the interface to control its state change. The monitoring control display module transmits the change to the digital switch quantity analysis combination module through message transmission. The digital switch quantity analysis combination module converts it according to the switch quantity type, port / bit number and other information and sends it to the underlying hardware interface module. The underlying hardware interface module adaptively matches the corresponding hardware driver interface according to the switch quantity type to control the switch quantity state of the inertial product.

[0039] The following is a specific embodiment:

[0040] The digital switch quantity detection device of the inertial measurement system of the present invention mainly consists of four parts: Figure 1 As shown, it includes a monitoring control display module, a digital switch quantity analysis and combination module, a configuration file module, and a bottom hardware communication interface module.

[0053] Before the test starts, press Figure 5 The switch configuration file loading process loads all switch configuration file information. After reading a switch information in the configuration file, it generates a switch information object after parsing. The switch information object is managed in a memory linked list. During the switch configuration file loading process, a memory index number, i.e. a unique identification number, is added for switch information query. The form of the linked list in memory is shown in Figure 3 .

[0054] Initialize the interface according to the linked list information, and finally form an interface such as Figure 7 shown.

[0055] From the above implementation examples, it can be seen that the switch quantity related parameters are all in the configuration file, and the configuration file is dynamically loaded before testing, so there is no need to worry about changes in the switch quantity port / bit number, type, etc., which simplifies the workload.

[0056] The characteristics of the present invention are as follows:

[0057] 1) All switch parameters are saved in the configuration file. The parameter configuration file can be dynamically configured according to different test requirements. Once the switch parameters are changed, you only need to reconfigure the parameter file according to the change requirements;

[0058] 2) The monitoring control display interface is dynamically generated according to the configuration file, which is convenient for software development or users to change the switch detection scheme, and does not rely on other software and hardware content;

[0059] 3) The switch quantity information is managed in an object manner and stored in a data linked list. Each object has a unique index number for easy query, which improves the real-time performance of the test;

[0060] 4) Different types of switch quantities can be managed in a unified manner and adaptively matched to different hardware driver interfaces, thereby meeting the specific requirements of most switch quantity detections, making the application of the present invention more extensive.

[0061] The above description of the preferred embodiments of the present invention is merely exemplary in nature and is not intended to limit the present invention, its application or use. Therefore, the protection scope of the present invention is not limited to these schemes and details. Without departing from the basic principles of the present invention, those skilled in the art can make modifications or equivalent substitutions to these schemes and details, and the modified or substituted embodiments will also fall within the protection scope of the present invention.
