Detailed Description
The present disclosure now will be described more fully hereinafter with reference to the accompanying drawings, in which exemplary embodiments of the disclosure are shown. The technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the drawings in the embodiments of the present disclosure, and it is obvious that the described embodiments are only a part of the embodiments of the present disclosure, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments disclosed herein without making any creative effort, shall fall within the protection scope of the present disclosure.
Fig. 1 is a schematic flow chart of an embodiment of a method for controlling the operation of an equipment assembly according to the present disclosure, as shown in fig. 1:
And 102, if so, saving the current control parameters of the equipment set and starting the independently operated communication module.
And 103, the communication module acquires the current control parameters, communicates with the equipment unit, and controls the operation of the equipment unit according to preset unit operation control rules and the current control parameters.
In practical engineering application, problems of application programs such as a touch screen controller program and the like are generally found due to interface operation and logic processing. The communication module is simple in logic and fixed in API, so that a bug which can cause program crash hardly occurs in the actual use process, and when an application program for controlling the equipment unit crashes and abnormally exits, the communication module can be operated as a single application to continuously maintain the communication with a mainboard of the equipment unit, and the operation of the unit is controlled.
In one embodiment, the application program used for controlling the equipment set can be various, such as a touch screen controller program and the like, the operating system in which the application program is located comprises an operating system of a display panel controller and the like, and the operating system of the display panel controller can be an operating system of android, red hat L inux and the like.
The application program receives the abnormal signal, and the abnormal detection module acquires the abnormal signal to detect whether the application program is abnormally exited or not and whether the application program is crashed or not.
In one embodiment, the anomaly detection module may be embedded in the application program as a functional module, and may communicate with other functional modules in the application program by means of variables or the like. For example, after the exception detection module detects an exception signal sent by the system, the variable T1 is set to an exception signal value, where the exception signal value may be an integer value, and a value of "1" indicates that the exception signal is detected, so as to determine that the application program performs an exception exit operation. The remaining functional modules of the application (e.g., exception handling module) may determine whether the application exits abnormally by checking the value of T1.
The current control parameters of the equipment unit can be saved through the exception handling module, and the independently operated communication module is started. The exception handling module may be implemented in various ways, for example, the exception handling module is a functional module in the application program, is not an independent process, and is started along with the starting of the application program. The exception processing module and the exception detection module can directly carry out information transfer by accessing variable values.
The communication module can be an independent process, the communication module can be started by calling a system function provided by an operating system where an application program is located, and the communication module runs in the operating system after being started.
For example, in the running process of the application program, the exception handling module records the current control parameters of the equipment set into F L ASH, and after the communication module is started, the communication module can issue the control parameters to the equipment set to control the equipment set.
In one embodiment, the communication module does not have all functions of the application program, and the unit operation control rule preset in the communication module can be set according to a specific control requirement. The communication module receives the unit operation parameters sent by the equipment unit, generates control instructions corresponding to the unit operation parameters according to the unit operation control rules and the current control parameters, and sends the control instructions to the equipment unit. For example, after receiving data sent by a motherboard of the equipment unit, the communication module processes corresponding data according to the unit operation control rule and the acquired current control data, and can execute unit operation control.
The communication module and the main board of the equipment set can transmit control parameters, such as: compressor current, electronic expansion valve opening, chilled exit water temperature, etc. The control mode according to the preset unit operation control rule and the current control parameter is as follows: and determining that the target freezing outlet water temperature is 10 ℃ based on the obtained current control parameters, obtaining the detected freezing outlet water temperature sent by the host by the communication module, and sending a control instruction to the host by the communication module when the freezing outlet water temperature reaches 10 ℃, so as to reduce the running frequency of the compressor and enable the unit to enter a standby state.
Before starting the communication module, releasing resources occupied by the application program, wherein the resources comprise: memory resources, file resources, device resources, and the like. The device resources may include network port resources, serial port resources, and the like. Resources may be released by calling an application programming interface provided by the operating system in which the application resides. The operating system may provide an API function for resource application and a corresponding resource release API function, for example, apply for a memory through a malloc function, release a memory through a free function, Open a file through an Open function, close a file through a close function, and the like, and release a memory resource applied by an application program and a device resource being used (e.g., an ethernet device, a 485 device, a can device, and the like). And after the current control parameters are determined to be stored and the resources are successfully released, starting the communication module, and after the communication module is started, the application program is abnormally exited.
When the application program crashes, an abnormal signal sent by the operating system is received, the abnormal detection module detects the abnormality, determines that the application program performs abnormal exit operation, and calls the abnormal processing module. The exception handling module releases the resources occupied by the current application program so as to avoid resource conflict when the independent communication module is started. And the exception handling module stores the current control parameters of the equipment unit. After the current control parameters of the occupied resource releasing and saving equipment unit are finished, the independent communication module is started to operate independently, and communication with the mainboard of the equipment unit is continued.
The exception handling module stores the current control parameter in a preset format in the storage module, and the communication module reads the current control parameter based on the same format after starting, so that the current control parameter can be transmitted to the independent communication module after successfully starting a program of the communication module. The communication module can ensure that the control parameters of the equipment unit are consistent based on the current control parameters. After the communication module is started, the application program is quitted, and the application program can be started when the system is restarted next time.
The independently started communication module is responsible for continuing communication with the mainboard of the equipment unit, so that normal communication with the mainboard can be maintained, and the operation of the unit can be controlled. Communication module operates in the operating system of display panel controller, and the display panel controller passes through interface module and equipment unit's mainboard connection, and interface module includes: bus interface module, network interface module, etc. The communication module can communicate with the mainboard of the equipment unit in various modes, for example, the communication module communicates with the mainboard through 485 buses, and a modbus communication protocol is adopted.
Fig. 2 is a schematic flow chart of another embodiment of a method for controlling the operation of an equipment assembly according to the present disclosure, as shown in fig. 2:
in step 201, the operating system sends an exception signal to the application program.
And step 204, judging whether the parameter storage and the resource release are successful, if so, entering step 205, and if not, ending.
And step 207, the communication module acquires the current control parameters and communicates with the equipment unit to control the operation of the equipment unit.
In one embodiment, as shown in fig. 3, the present invention provides an apparatus for controlling an operation of an equipment set, comprising: an anomaly detection module 31, an anomaly handling module 32 and a communication module 33. The anomaly detection module 31 detects an anomaly signal received by an application program for controlling the equipment set, and determines whether the application program performs an anomaly exit operation based on the anomaly signal. If the application program is determined to perform the abnormal exit operation, the abnormal processing module 32 saves the current control parameters of the equipment unit and starts the communication module 33 which operates independently. The communication module 33 obtains the current control parameter and communicates with the equipment unit, and controls the operation of the equipment unit according to the preset unit operation control rule and the current control parameter.
In one embodiment, the communication module 33 receives the unit operation parameters sent by the equipment unit, generates a control instruction corresponding to the unit operation parameters according to the unit operation control rule and the current control parameters, and sends the control instruction to the equipment unit.
The exception handling module 32 stores the current control parameters in the storage module. After the communication module 33 is started, the current control parameters are obtained from the storage module. Before starting the communication module, the exception handling module 32 releases resources occupied by the application program, where the resources include: memory resources, file resources, device resources, and the like. After determining that the current control parameters are saved and the resources are released successfully, the exception handling module 33 starts the communication module 34, and after the communication module 34 is started, the application program exits abnormally.
Exception handling module 32 releases the resource by calling an application programming interface provided by the operating system in which the application resides. The exception handling module 32 starts the communication module 33 by calling a system function provided by the operating system where the application program is located, and the communication module 33 runs in the operating system after being started.
