Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, specific embodiments of the present application are described in detail below with reference to the accompanying drawings. It is to be understood that the specific embodiments described herein are merely illustrative of the application and are not limiting of the application. It should be further noted that, for the convenience of description, only some but not all of the relevant portions of the present application are shown in the drawings. Before discussing exemplary embodiments in more detail, it should be noted that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although a flowchart may describe the operations (or steps) as a sequential process, many of the operations can be performed in parallel, concurrently or simultaneously. In addition, the order of the operations may be re-arranged. The process may be terminated when its operations are completed, but may have additional steps not included in the figure. The processes may correspond to methods, functions, procedures, subroutines, and the like.
The exception handling method for the system parameters of the control program provided by the embodiment of the application aims to avoid the exception of some system parameters from becoming zero through exception handling. In the use process of the heat pump system, all loads (such as a compressor, a fan, a water pump, a four-way valve, an electronic expansion valve and the like) in the heat pump system need to be coordinated through a main board of the heat pump system. The main board is programmed with a heat pump control program, and the heat pump control program includes system parameters (such as fan parameters, system number, etc.) for controlling the operation of each load of the heat pump system. When the mainboard is powered on, the system parameters stored in the internal memory are read, and the system parameters are synchronized to the external control end. And the external control end is used for displaying system parameters and state parameters and realizing input control on the heat pump system. When some system parameters which cannot be zero in a heat pump control program are abnormal and change to zero, the control logic corresponding to '0' is not arranged in the mainboard, so that corresponding tasks cannot be executed, the response among all loads of the unit cannot be realized, and the unit is abnormally operated, so that the unit cannot work and is broken down. Obviously, the heat pump system may affect the operation of the machine when the system parameter becomes zero, and further affect the actual experience of the user. Therefore, the method for processing the abnormality of the system parameter of the control program in the embodiment of the application is provided to solve the problem that the normal operation of the heat pump system is affected due to the abnormal zero of the system parameter.
Implementing one step:
fig. 1 is a flowchart of an exception handling method for a control program system parameter according to an embodiment of the present application, where the exception handling method for a control program system parameter provided in this embodiment may be executed by an exception handling device for a control program system parameter, the exception handling device for a control program system parameter may be implemented in a software and/or hardware manner, and the exception handling device for a control program system parameter may be formed by two or more physical entities or may be formed by one physical entity. Generally, the abnormality processing device of the control program system parameter may be a main board of the heat pump system.
The following description will be made by taking a main board of the heat pump system as an example of a method for processing an abnormality that executes system parameters of a control program. Referring to fig. 1, the method for processing an exception of a system parameter of a control program specifically includes:
s110, presetting a parameter which can not be zero in each system parameter in a control program as an identification parameter;
s120, when the mainboard is powered on, reading system parameters from a mainboard memory, and judging whether parameter values on the identification parameter bits in the system parameters are zero or not;
s130, restoring the system parameter with the parameter value of zero on the identification parameter to a default value, wherein the default value is stored in the mainboard memory;
and S140, synchronizing all system parameters to an external control end.
For example, in order to accurately determine whether a parameter value that cannot be zero in a system parameter becomes zero, parameter bits that cannot be zero in each parameter value in the system parameter are identified in advance on the motherboard, and the parameter bits are set as identification parameter bits. The identification parameter digit is used for judging whether the parameter value on the identification parameter digit is zero or not when abnormality detection is carried out subsequently, so that whether the abnormal zero change of the system parameter occurs in the current heat pump system control program or not can be determined.
Referring to fig. 2, when the system parameters stored in the motherboard memory (EEPROM) are electrically read on the motherboard, the detection that the system parameters are abnormally zero is performed. And judging whether the parameter value on the identification parameter digit is zero or not based on the preset identification parameter digit. For example, the parameter value of the preset parameter digit "Y" cannot be set to zero, when the motherboard circularly reads the system parameter on the motherboard memory, the motherboard determines whether the parameter value of the parameter digit "Y" is zero, and if the parameter value of the parameter digit "Y" is not zero, the motherboard normally reads the system parameter information corresponding to the parameter digit "Y" from the memory; if the parameter value of the parameter bit "Y" is zero, it indicates that the parameter information stored in the parameter bit "Y" corresponding to the current motherboard memory is incorrect, and the motherboard directly extracts the default parameter value of the parameter bit "Y" from the motherboard memory, and restores the parameter value of the parameter bit "Y" to the default value. It should be noted that the main board memory stores the system parameters set by the heat pump system control program in daily use, and stores the system parameters initialized by the main board as default values of the system parameters. Finally, the parameter bit "Y" restores the system parameter value to a default value, and stores the default value in the system parameter of the motherboard memory, replaces the parameter value of which the parameter bit "Y" becomes zero, and uses the default value as the parameter value of the parameter bit "Y" in the system parameter.
After the mainboard reads all system parameters of the heat pump system control program from the memory, all the system parameters are synchronously displayed on the external control end, and meanwhile, the external control end can realize remote control of the heat pump system based on the system parameters.
Specifically, referring to fig. 3, the synchronization of the system parameters includes:
s1401, pushing all system parameters to an external control end;
s1402, judging whether communication abnormity occurs according to the response of the external control end;
and S1403, when communication is abnormal, pushing all system parameter setting times again until communication is normal.
When the mainboard pushes the system parameters to the external control end, the response made by the external control end according to the receiving result can be received in real time, if the response of the external control end is not received, the communication abnormity is considered to happen currently. In order to ensure that the external control end receives system parameter information as much as possible, and avoid the situation that the external control end becomes abnormally zero due to abnormal communication in the system parameter pushing process, a retransmission mechanism of the system parameters is triggered when the communication is abnormal, and all the system parameter setting times are pushed again until the communication is normal. The retransmission mechanism can effectively prevent the system parameter from changing to zero due to data frame loss, and reduce the probability of changing to zero when the system parameter is abnormal.
Taking parameter pushing between the motherboard and the line controller as an example, referring to fig. 4, when system parameters are synchronized, the motherboard pushes system parameter data to the line controller through a system parameter pushing instruction. When the system parameters are pushed, the system parameters are divided into a plurality of frame data, each frame data comprises 90 system parameters, and the system parameter data are sent frame by frame. If the line controller responds to each frame of system parameter data, the current communication is normal, and after the system parameter data is sent, the real-time state parameters of the current heat pump system are sent to the line controller, so that the line controller displays all state parameters of the heat pump system. If the mainboard does not receive the response of the wire controller corresponding to a certain frame of parameter data, namely the communication is abnormal, the mainboard retransmits the system parameter push instruction and pushes the frame of system parameter data. The mainboard repeats three times at most, and after the communication is abnormal and cannot be recovered temporarily, the mainboard directly sends the real-time state parameters of the current heat pump system.
In the above, by presetting the identification parameter bits, where the system parameter cannot be zero, on the motherboard, when the motherboard is powered on, the system parameter is read from the motherboard memory, and whether the parameter value on the identification parameter bit in the system parameter is zero is judged, the system parameter with the parameter value on the identification parameter bit being zero is restored to a default value, and all the system parameters are synchronized to the control end, so as to avoid abnormal zero change of the system parameter on the motherboard, ensure real-time response to control of each load of the heat pump system, and enable the heat pump system to work normally.
And when the system parameters of the main board are synchronized to the external control end, the response of the external control end is received in real time to judge whether the communication is abnormal or not, if the communication is abnormal, a retransmission mechanism of system parameter data is triggered, so that the situation that the external control end cannot receive the system parameter data is avoided as much as possible, and the situation that the system parameters cause the corresponding system parameters of the external control end to become zero due to data frame loss, and further the external control end cannot control the heat pump system is prevented.
Example two:
on the basis of the foregoing embodiment, fig. 5 is a flowchart of another exception handling method for system parameters of a control program according to a second embodiment of the present application. Referring to fig. 5, the method for processing an exception of a control program system parameter provided in this embodiment specifically includes:
s210, presetting a parameter bit, which is not zero in each system parameter in the control program, as an identification parameter bit;
s220, when the mainboard is powered on, reading system parameters from a mainboard memory, and judging whether parameter values on the identification parameter bits in the system parameters are zero or not;
s230, restoring the system parameter with the parameter value of zero on the identification parameter to a default value, wherein the default value is stored in the mainboard memory;
s240, judging whether the system parameter on the identification parameter digit is zero or not at intervals of a set time period, and reading the corresponding system parameter from the mainboard memory again for the identification parameter digit with the system parameter being zero;
and S250, synchronizing all system parameters to an external control end.
Illustratively, after the system parameters in the memory are electrically read on the motherboard, the loop judgment of the current system parameters is also performed. Due to artificial unreasonable operation, the abnormal conditions inside the main board and the like can cause the abnormal zero of the system parameters. Therefore, the system parameters on the motherboard need to be circularly detected, and whether the parameter values on the identification parameters are zero or not is judged. And if the corresponding identification parameter bit parameter value is zero, re-reading the corresponding system parameter from the mainboard memory.
Specifically, referring to fig. 6, based on the preset flag parameter, it is determined every 0.5s cycle whether the parameter value on the flag parameter is zero. If the parameter value on the identification parameter bit is zero, the data is judged to be abnormal, at the moment, the mainboard rereads all system parameters once from the memory, and then all the parameters of the mainboard are synchronously fed to the line controller once. If the parameter value on the identification bit is not zero, the data is judged to be normal, and the mainboard continues to perform circulating judgment. It should be noted that the cycle judgment of the system parameters by the motherboard is continuously performed after the motherboard is powered on, and after the system parameters are reread, the synchronization of the system parameters is performed by the motherboard every time the system parameters are reread in order to avoid the inconsistency of the system parameters synchronized to the line controller before.
According to the scheme, the system parameters on the main board are judged to become zero through circulation, re-reading of all the system parameters is triggered according to the condition that the system parameters are changed into zero abnormally, so that the main board system parameters are correct, the influence of the abnormal system parameters on the normal work of the heat pump system is avoided, and the use experience of a user on the heat pump system is further optimized.
Example three:
on the basis of the foregoing embodiments, fig. 7 is a flowchart of another exception handling method for system parameters of a control program according to a third embodiment of the present application. Referring to fig. 7, the method for processing an exception of a control program system parameter provided in this embodiment specifically includes:
s310, presetting a parameter which can not be zero in each system parameter in a control program as an identification parameter;
s320, when the mainboard is powered on, reading system parameters from a mainboard memory, and judging whether parameter values on the identification parameter bits in the system parameters are zero or not;
s330, restoring the system parameter with the parameter value of zero on the identification parameter to a default value, wherein the default value is stored in the mainboard memory;
s340, synchronizing all system parameters to an external control end;
s350, receiving parameter change information of the external control end corresponding to the identification parameter in real time, and not analyzing the parameter change information with a parameter change value of zero;
and S360, if the parameter change value of the parameter change information of the external control end corresponding to the identification parameter is zero, synchronizing all current system parameters to the external control end again.
For example, in the embodiment of the present application, after synchronizing the system parameters to the external control end, the parameter change information of the external control end on a certain system parameter is performed in real time. If the system parameter modified by the external control end does not belong to the identification parameter number, the parameter value on the corresponding parameter number is modified directly according to the parameter modification information. If the parameter value on the identification parameter bit is modified, it needs to be judged whether the parameter modification value of the identification parameter bit is 0, and the parameter modification information with the parameter modification value of zero is not analyzed.
Specifically, referring to fig. 8, taking the line controller as an example, when the line controller changes the parameter value of the identification parameter bit "Y" (at this time, the identification parameter bit "Y" is set to 1), the motherboard reads back the parameter packet of the changed identification parameter bit "Y" parameter value through the system parameter read-back command. Determining whether the parameter modification value for the identification parameter bit "Y" is zero or not corresponding to the parameter packet. At this time, if the parameter modification value is zero, the parameter packet is determined to be abnormal, and the parameter packet is not analyzed, and naturally the system parameter data storage of the main board memory is not triggered. And simultaneously, all parameters of the current mainboard are synchronously fed to the line controller at one time, so that the condition that the system parameters are abnormally changed to zero due to the fact that the line controller changes the parameter value of the identification parameter digit Y is avoided. And if the parameter modification value corresponding to the identification parameter bit Y is not zero, the parameter packet is judged to be normal, the data of the parameter packet is analyzed, and then the mainboard memory is triggered to store the system parameter data, so as to ensure that the modification of the related system parameters can be synchronized into the mainboard memory.
According to the scheme, the parameter change information for identifying the parameter is detected by the external control end, whether the parameter change value is zero or not is judged, and if the parameter change value is zero, the parameter change information is not analyzed. The abnormal change of the system parameters of the identification parameter digit caused by communication abnormity or error change of the system parameters by an external control end when the system parameters are read back by the mainboard is avoided, the normal response of the control of the heat pump system is ensured, and the use experience of a user is further optimized.
Example four:
on the basis of the foregoing embodiment, fig. 9 is a flowchart of another method for processing an exception of a system parameter of a control program according to a fourth embodiment of the present application. Referring to fig. 9, the exception handling method for system parameters of the control program provided in this embodiment may be executed by an external control end of the heat pump system, and generally, the external control end may be a control end such as a line controller (e.g., a display for human-computer interaction, such as a remote control, a color screen, an LED, an LCD), a centralized control end, or a DTU module.
The following description will be made by taking a line controller of a heat pump system as an example of a main body of an abnormality processing method for executing system parameters of a control program. Referring to fig. 9, the method for processing an exception of a control program system parameter specifically includes:
s410, presetting a parameter bit which can not be zero in each system parameter in a control program as an identification parameter bit;
s420, receiving all system parameters uploaded by the mainboard;
s430, judging whether the system parameter on the identification parameter is zero or not at intervals of a set time period;
and S440, if the system parameter on the identification parameter is zero, reading all system factory parameters stored in an external control end memory, and synchronizing the system factory parameters to the mainboard.
For example, in order to accurately determine whether a parameter value that cannot be zero in a system parameter changes to zero, parameter bits that cannot be zero in each parameter value in the system parameter are identified in advance on the line controller, and the parameter bits are set as identification parameter bits. The identification parameter digit is used for judging whether the parameter value on the identification parameter digit is zero or not when abnormality detection is carried out subsequently, so that whether the abnormal zero change of the system parameter occurs in the current heat pump system control program or not can be determined.
And then, the line controller receives all the system parameters synchronized by the mainboard, and judges the received system parameters by abnormal detection every set time period. And judging whether the parameter value on the identification parameter digit is zero or not based on the preset identification parameter digit. And considering that the system parameters on the current mainboard are abnormal under the condition that the parameter values on the identification parameter digits are zero, reading system factory parameters of a heat pump system control program stored in a memory (an EEPROM (electrically erasable programmable read-only memory)) of the line controller by the line controller, and sending the system factory parameters to the mainboard to replace the system parameters on the mainboard.
Specifically, referring to fig. 10, the line controller sets the parameter value of the parameter "Y" not to be zero in advance, and determines whether the parameter value of the parameter "Y" is zero every 0.2s cycle. When the parameter value of the parameter digit Y is detected to be zero, the line controller triggers a download recovery mechanism, reads all system delivery parameters once from a memory of the line controller, and synchronizes all system delivery parameters once to the mainboard. The system delivery parameters are stored in a memory of the online controller when the heat pump system is delivered, and the system delivery parameters can be restored to the mainboard through the online controller.
In addition, when receiving the system parameter data synchronized by the main board, the line controller can judge whether packet loss occurs in the current system parameter synchronization operation in real time, if the packet loss occurs, the main board is requested to resend all data, and the normal transmission of the system parameter data is ensured through a resending mechanism.
The identification parameter bits with the system parameters which cannot be zero are preset at the external control end of the heat pump system, then the system parameters on the identification parameter bits are judged to be zero or not in a circulating mode, if the identification parameter bits with the system parameters which are zero are judged to exist, all system delivery parameters stored in the storage are read, the system delivery parameters are synchronized to the mainboard, the condition that the system parameters of the external control end and the mainboard are abnormally changed into zero is avoided, the external control end can normally control the heat pump system, real-time response to control of each load of the heat pump system is guaranteed, and use experience of a user is optimized.
Example five:
on the basis of the foregoing embodiments, fig. 11 is a schematic structural diagram of an exception handling apparatus for controlling system parameters of a program according to an embodiment of the present application. Referring to fig. 11, the apparatus for processing an exception of a control program system parameter provided in this embodiment specifically includes: a presetting module 51, a judging module 52, a recovering module 53 and a synchronizing module 54.
The preset module 51 is configured to preset a parameter that each system parameter in the control program cannot be zero as an identification parameter;
the judging module 52 is configured to, when the motherboard is powered on, read a system parameter from the motherboard memory, and judge whether a parameter value on the identification parameter bit in the system parameter is zero;
the restoring module 53 is configured to restore the system parameter with a parameter value of zero in the identification parameter to a default value, where the default value is stored in the motherboard memory;
the synchronization module 54 is used to synchronize all system parameters to the external control end.
In the above, by presetting the identification parameter bits, where the system parameter cannot be zero, on the motherboard, when the motherboard is powered on, the system parameter is read from the motherboard memory, and whether the parameter value on the identification parameter bit in the system parameter is zero is judged, the system parameter with the parameter value on the identification parameter bit being zero is restored to a default value, and all the system parameters are synchronized to the control end, so as to avoid abnormal zero change of the system parameter on the motherboard, ensure real-time response to control of each load of the heat pump system, and enable the heat pump system to work normally.
Specifically, still include:
and the rereading module is used for judging whether the system parameters on the identification parameter bits are zero or not at intervals of a set time period, and rereading the corresponding system parameters from the mainboard memory for the identification parameter bits with the system parameters being zero.
