Detailed Description
The principles and embodiments of the present invention are described in detail below with reference to the accompanying drawings.
As shown in fig. 1, in a preferred embodiment of the present invention, the communication debugging device includes a load connection module, a protocol acquisition module, a human-computer interaction module, an interface conversion module, and a debugging module.
The load connection module is used for connecting corresponding equipment to be tested, and comprises a plurality of common communication interfaces such as USB, HomeBus, RJ45, CAN, RS485, RS232 and the like in order to adapt to different equipment to be tested. The communication interfaces contained in the load connection module can be 2 or more, so that the development quantity of corresponding test tools is reduced. On the basis, when a communication interface which is not contained in the load connection module appears, the interface conversion module which can be connected in a pluggable mode can be used for converting the existing communication interface in the load connection module into a communication interface matched with the equipment to be tested. Therefore, the mainboard of the tested device does not need to prepare a hardware connection interface (communication interface) specially used for testing during design, and can use USB communication through the corresponding interface conversion module without using the communication interface frequently, so that the communication debugging device can be suitable for most communication debugging.
After the communication debugging equipment is connected with the equipment to be tested, a user is required to input a communication interface connected with the equipment to be tested and corresponding interface parameters through the man-machine interaction module. When the communication interface is HomeBus, CAN, RS485, RS232, the corresponding interface parameters include one or more of baud rate, stop bit, check bit, and data length. And when the communication interface is the USB, the corresponding interface parameter is null. And when the communication interface is RJ45, the corresponding interface parameter is the IP address of the equipment to be tested. The man-machine interaction module of the invention preferably adopts a touch screen.
Correspondingly, the protocol acquisition module needs to prepare the communication protocol corresponding to each communication interface for the debugging module to use. In one embodiment, various communication protocols (e.g., IEC101, IEC104, etc.) conforming to multiple industry standards are maximally integrated on the portable communication debugging device of the present invention by means of the pluggable mobile memory card. The removable memory card may be an SD card, a TF card, or the like. Of course, the internal protocol of the enterprise can also lead the protocol acquisition module into the communication debugging device of the invention through a storage mode such as an SD card and the like. In another embodiment, the corresponding communication protocol, such as an enterprise internal protocol, may also be input through the human-machine interaction module. In a preferred embodiment, the technical solutions in the two embodiments may be adopted at the same time, so that a user may provide different communication protocols to the communication debugging device according to the situation, and the protocol acquisition module may select a corresponding communication protocol according to a communication interface to which the device to be tested is accessed.
In one embodiment, the content of the communication protocol of the present invention specifically includes: the communication debugging equipment is used as one or more of an upper computer or a lower computer, corresponding data frame contents, sending time intervals and whether to send circularly. And then the debugging module controls the protocol acquisition module to select a corresponding communication protocol for communication debugging and receive feedback data of the equipment to be tested according to the communication interface connected with the equipment to be tested and corresponding interface parameters.
Fig. 2 shows an interface displayed when the touch screen is used as the human-computer interaction module, a standard protocol button on the interface may select a corresponding protocol, such as IEC101 or IEC104, and the protocol creating button may enable a user to create a protocol, which requires the user to perform a specific input operation using a keyboard operation button. The parameter setting is used for setting the specific content of the communication protocol, including whether the communication debugging equipment is used as an upper computer or a lower computer, the execution times of data frames, time intervals, whether the data frames are circulated or not and the like. The message monitoring button can provide a message receiving and sending monitoring window for a user, and the user can open the message monitoring window or not, and can click in the message monitoring window to store the message. The start/stop button is used for the debugging module to send a start instruction and a stop instruction. The interface selection button is a communication interface (such as USB, RJ45, RS232 or other bus type communication interfaces) for selecting the device under test to access. The load setting button can send instructions to the load connection module to associate loads, name loads, delete loads, add loads, and the like. The keyboard operation may provide a soft keyboard for the user to make corresponding inputs.
Taking the test of the load of the air conditioner as an example, the communication debugging equipment of the invention mainly tests the load (whether the load can work normally or not, and whether the load has damage or not, such as a stepping motor, a relay, a lamp panel display and the like) or partial operation logic of the load. For example, when testing the household air conditioner, the debugging module serves as an upper computer according to a communication protocol, firstly sends a string of data frames, only modifies the wind sweeping action in the content of the data frames, can enable the wind sweeping to continue for a period of time by setting the sending times, the interval time and the like of the string of data frames, achieves the aim of testing whether the stepper motor works normally, enables the communication debugging equipment to simulate the corresponding communication protocol to further serve as the role of the upper computer when testing other loads, and reads or operates the equipment to be debugged through the setting parameters, the fault parameters, the state parameters and the like in the content of the data frames of the communication protocol. The test is finished on the touch screen of the communication debugging equipment from the beginning of sending the first frame data frame to the completion of the test of all the loads to be tested, the whole debugging module does not need human participation in the process of carrying out the load test, and all the loads to be tested can be tested, namely the test of the loads is automatically finished.
In the test process, the feedback data returned by the device to be tested is response data which is sent by the device to be tested according to the role of the upper computer or the lower computer played by the communication debugging device and responds to the content of the data frame. The user may set the display or not of the response data, or may select whether to store the response data. And then the debugging module sends the feedback data to a man-machine interaction module (a touch screen) and/or a mobile memory card according to the setting of the user. When the feedback data is sent to the touch screen, the user can monitor the messages in the test process at any time (all the messages fed back by the device to be tested in the test process form the feedback data).
When the communication debugging equipment is filled in the lower computer, the digital values of some sensors can be set by the communication debugging equipment to replace the measured values of the real sensors for data exchange.
Taking the development of the program of the internal machine mainboard as an example, the RS485 interface needs to be used for communicating with the line controller for testing, but a technician possibly responsible for the development of the line controller cannot provide the line controller and the program temporarily, and at this time, the communication debugging device can be used for testing. Because the communication interface of the internal machine mainboard is RS485, after the communication debugging equipment is connected with the internal machine mainboard, the corresponding communication interface RS485 is selected, and then interface parameters such as serial port numbers and stop positions are set for communication connection. At this time, a corresponding communication protocol can be created through the touch screen, and the data frame to be sent can be knocked out by using the touch screen or an external keyboard. Through the parameter setting of the communication protocol, whether the communication debugging equipment is used as an upper computer or a lower computer is firstly determined, and then parameters such as sending times, circulation and the like are set for a data frame to be sent, so that the debugging purpose is achieved. After the data message corresponding to the data frame is sent, the message monitoring part can see the message (response data of the device to be tested) sent and received by the message monitoring part. For example, in the online test of the air conditioner, aiming at the condition of testing the loads, a plurality of data frames which can enable the loads to be tested to act can be stored in advance, parameters such as time intervals and the like are set, and normal test can be carried out by clicking to debug. The effect and efficiency of the invention are more easily shown in batch test.
The invention can import or create the protocol, if the protocol is created and debugged once, the protocol can be stored, the protocol can be directly opened for operation next time after being stored, the creation of time is not needed again, the follow-up batch test only needs to be called, and the production test efficiency is improved. Specifically, parameters such as the number of sending times of the data frame, the time interval, whether to circulate and the like can be modified, so that the manual operation test can be simulated, and the test can be automatically completed within the specified time. In addition, the debugging can be performed completely through the data frame in operation, and a corresponding graphical interface can be provided to assist an operator in debugging, for example, a corresponding graphical interface is provided for the device to be tested. The invention can simulate the measured value of the sensor to exchange data when no sensor exists, and no matter what kind of interface to be tested faces the equipment to be tested, the hardware communication interface specially used for testing is not needed to be designed for the equipment to be tested, and the communication interface which is not commonly used can use USB communication through the corresponding converter, thereby being applicable to most communication debugging. The communication debugging equipment is connected with a computer through a network cable, and then the display of the touch screen is mapped to a webpage of the computer for operation.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
