[0033] Embodiment one

[0034] Figure 1A A flow chart of a method for initializing parameters of a unit is provided for the first embodiment of the present application. The present embodiment can be applied to the case of initializing parameters of a unit. The method can be executed by a unit parameter initialization device. The unit parameter initialization device can be realized in the form of hardware and / or software. The unit parameter initialization device can be configured in the unit. As shown in the figure, the method comprises the following steps. Figure 1A

[0035] S110, after the unit is powered on, reading target unit parameter values stored in a three-level parameter storage area based on a three-level parameter storage mechanism; wherein the three-level parameter storage area comprises a settable storage area, a fixed storage area and an initial storage area; the initial storage area is located in the internal memory of the unit.

[0036] In the present embodiment, the control board in the unit is used to execute the initialization operation of the unit parameters. The target unit parameter values can be understood as the correct unit parameter values required in the initialization process of the unit parameters.

[0037] The three-level parameter storage mechanism can be understood as a parameter storage and read-write mechanism based on the three-level parameter storage area. The unit opens up three-level parameter storage areas of the settable storage area, the fixed storage area and the initial storage area from a specific memory, which are used to store specific types of unit operation parameters respectively. The settable storage area is used to store the settable unit operation parameters, which saves the unit operation parameters changed by the user in real time during the unit operation process. The fixed storage area is used to store the factory parameters of the unit, and the parameters cannot be changed. The initial storage area is used to store the fixed factory parameters of the unit, which are readable and non-writable and located in the internal memory of the unit. The internal memory may, for example, be a solid-state semiconductor memory ROM of the MCU chip of the control board.

[0038] ​Specifically, after the unit is powered on, the control board runs an initialization function to automatically execute a three-level parameter storage mechanism to read correct target unit parameter values from the corresponding storage.

[0039] Specifically, the three-level parameter storage mechanism can be used to read target unit parameter values from the settable storage area first after the unit is powered on. If the parameters stored in the settable storage area are abnormal, the unit automatically switches to the fixed storage area to obtain the factory parameters to ensure normal operation of the unit. If the parameters stored in the settable storage area and the fixed storage area are abnormal, the unit automatically switches to the initial storage area to obtain the factory parameters to ensure normal operation of the unit.

[0040] Optionally, the settable storage area and the fixed storage area are located in a target storage of the unit, and the target storage includes an internal storage and / or at least one external storage of the unit.

[0041] The internal storage refers to the internal Flash memory of the MCU chip of the control board, and the external storage refers to the external chip memory such as an EEPROM memory.

[0042] Specifically, according to actual development requirements and unit interference, the internal storage, the external storage, and the multiple composite three-level storage area of the internal and external storage are selected, and the corresponding three-level parameter storage mechanism is determined.

[0043] In one specific example, a single internal storage can be used to set the three-level parameter storage area. Figure 1B is a schematic diagram of using a single internal storage to set the three-level parameter storage area, as shown in Figure 1B The initial storage area is set in the solid-state semiconductor memory of the MCU chip of the control board. A special address 0x000-0x7FF is opened on the MCU chip as the settable storage area. A special address 0x800-0xFFF is opened on the MCU chip as the fixed storage area.

[0044] In another specific example, the internal storage can be used to set the initial storage area, and multiple storage (including internal storage and / or external storage) can be used for parameter storage of the settable storage area and the fixed storage area. The number of external storage is not limited. Figure 1C is a schematic diagram of using one internal storage and two external storages to set the three-level parameter storage area, as shown in Figure 1CAs shown, a three-level parameter storage area is set in an internal memory, and a dedicated address 0x000~0x7FF is opened in two external memories as a settable storage area, and a dedicated address 0x800~0xFFF is opened as a fixed storage area.

[0045] S120, the unit parameter variable is valued based on the target unit parameter value to obtain the unit operation parameter.

[0046] The unit parameter variable can be understood as a parameter composed of name and format attribute information. The unit operation parameter can be understood as a parameter that ensures the normal operation of the unit, and can be considered as a parameter with a fixed value obtained by assigning the unit parameter variable.

[0047] Specifically, the unit reads the target unit parameter value from the memory, and assigns the target unit parameter value to the corresponding unit parameter variable to obtain the unit operation parameter.

[0048] S130, when receiving the unit parameter query instruction of the host computer, the unit operation parameter is returned to the host computer.

[0049] The unit parameter query instruction can be understood as an instruction for querying the unit operation parameter read by the unit.

[0050] Specifically, the host computer sends a unit parameter query instruction to the unit, and the unit returns the unit operation parameter to the host computer when receiving the unit parameter query instruction of the host computer, thereby completing the initialization process of the unit parameter and making the unit enter the normal operation stage.

[0051] The technical scheme of the embodiment of the application reads the target unit parameter value stored in the three-level parameter storage area based on the three-level parameter storage mechanism after the unit is powered on. The three-level parameter storage area includes: a settable storage area, a fixed storage area and an initial storage area. The initial storage area is located in the internal memory of the unit. The unit parameter variable is valued based on the target unit parameter value to obtain the unit operation parameter. When receiving the unit parameter query instruction of the host computer, the unit operation parameter is returned to the host computer. Based on the three-level parameter storage mechanism, the accuracy of the read unit parameter is guaranteed, and the problem that the unit parameter is easily disturbed during the parameter initialization process of the unit, resulting in abnormal parameters of the unit, which cannot be normally started or even fails, is solved. The accuracy of the unit operation parameter during the parameter initialization process of the unit, the safety and reliability of the unit are improved, and the stable operation of the unit is ensured.

[0052] Optionally, when receiving the parameter value storage instruction sent by the host computer, if the received parameter value storage instruction is within the set range, the received parameter package is written into the settable storage area of the memory. The memory includes: internal memory or external memory.

[0053] Optionally, the writing of the received parameter value into the settable storage area of the memory comprises: writing a parameter package corresponding to the parameter value storage instruction into the memory after verification; and the reading of the written parameter comprises: verifying the written parameter package to determine whether the writing is successful.

[0054] Specifically, the verification manner can be comparing whether the header code and the CRC check code of the parameter package are consistent. If the writing is not successful, the writing is continuously performed until a preset writing number (such as three times) is reached, and if the writing is continuously failed, a fault signal is sent, and the unit operation is stopped.

[0055] Embodiment Two

[0056] Figure 2A A flowchart of a unit parameter initialization method provided by Embodiment Two of the present application, the present embodiment further limits the above-mentioned embodiment to the case where a first parameter storage area exists in the internal memory of the unit, and a second parameter storage area exists in the external memory of the unit. As shown in the figure, the method comprises: Figure 2A

[0057] S210, reading a target unit parameter value stored in the first parameter storage area of the internal memory after the unit is powered on; wherein the first parameter storage area comprises: a first settable storage area and / or a first fixed storage area; and the reading priority of the first settable storage area is higher than that of the first fixed storage area.

[0058] In the present embodiment, the first parameter storage area exists in the internal memory, and the first parameter storage area comprises: the first settable storage area and the first fixed storage area.

[0059] Specifically, after the unit is powered on, the control board in the unit runs an initialization function, so that the control board preferentially runs the internal storage mechanism to read the stored target unit parameter value from the first settable storage area or the first fixed storage area of the internal memory. Since the reading priority of the first settable storage area is higher than that of the first fixed storage area, the target unit parameter value stored in the first settable storage area of the internal memory is preferentially read, and if the target unit parameter value is abnormal, the target unit parameter value stored in the first fixed storage area is read.

[0060] S220, if the target unit parameter value stored in the first parameter storage area is abnormal, reading a target unit parameter value stored in the second parameter storage area of the external memory; wherein the second parameter storage area comprises: a second settable storage area and / or a second fixed storage area.

[0061] In the present embodiment, the second parameter storage area exists in the external memory, and the second parameter storage area comprises: the second settable storage area and the second fixed storage area. ​

[0062] Specifically, it is judged whether the target unit parameter value read in the first parameter storage area of the internal memory is abnormal, and if normal, step S240 is executed. If abnormal, the control board remains in the initialization state, and the external storage mechanism is run to read the stored target unit parameter value from the second settable storage area or the second fixed storage area of the external memory. Since the reading priority of the second settable storage area is higher than that of the second fixed storage area, the target unit parameter value stored in the second settable storage area is read first, and if the target unit parameter value is abnormal, the target unit parameter value stored in the second fixed storage area is read.

[0063] S230, if the target unit parameter value stored in the second parameter storage area is abnormal, the target unit parameter value stored in the initial storage area of the internal memory is read.

[0064] Specifically, it is judged whether the target unit parameter value read in the second parameter storage area of the external memory is abnormal, and if normal, step S240 is executed. If abnormal, the control board remains in the initialization state, and the target unit parameter value stored in the initial storage area of the internal memory is read. If the target unit parameter value read from the initial storage area is abnormal, the initialization state is exited, and the unit fails and does not run. If the target unit parameter value read from the initial storage area is normal, step S240 is executed.

[0065] S240, the unit running parameter is obtained by assigning the unit parameter variable based on the target unit parameter value;

[0066] S250, when the unit parameter query instruction of the upper computer is received, the unit running parameter is returned to the upper computer.

[0067] The technical scheme of the embodiment of the application comprises the following steps: after the unit is powered on, reading target unit parameter values stored in a first parameter storage area of an internal memory; the first parameter storage area comprises a first settable storage area and / or a first fixed storage area; the reading priority of the first settable storage area is higher than that of the first fixed storage area; if the target unit parameter values stored in the first parameter storage area are abnormal, reading target unit parameter values stored in a second parameter storage area of an external memory; the second parameter storage area comprises a second settable storage area and / or a second fixed storage area; if the target unit parameter values stored in the second parameter storage area are abnormal, reading target unit parameter values stored in an initial storage area of the internal memory; based on the target unit parameter values, assigning values to unit parameter variables to obtain unit operation parameters; when receiving a unit parameter query instruction from a host computer, returning the unit operation parameters to the host computer. By using the three-level parameter storage areas of the internal memory and the external memory and the corresponding three-level parameter storage mechanisms, the problem that the unit parameters are easily disturbed during the parameter initialization process of the unit, the unit cannot be normally started or even fails due to the abnormal parameters, the accuracy of the unit operation parameters during the parameter initialization process of the unit, the safety and reliability of the unit are improved, and the stable operation of the unit is ensured.

[0068] Optionally, in step S210, the reading of the target unit parameter values stored in the first parameter storage area of the internal memory comprises:

[0069] S211, reading a first target unit parameter value from the first settable storage area of the internal memory and determining whether the first target unit parameter value is abnormal.

[0070] The first target unit parameter value is a target unit parameter value stored in the first settable storage area of the internal memory; and the second target unit parameter value is a target unit parameter value stored in the first fixed storage area of the internal memory.

[0071] Specifically, the first parameter storage area of the internal memory comprises the first settable storage area and the first fixed storage area, and the reading priority of the first settable storage area is higher than that of the first fixed storage area. Therefore, the first target unit parameter value is read from the first settable storage area of the internal memory first, and it is determined whether the first target unit parameter value is abnormal; if the first target unit parameter value is normal, it indicates that the first target unit parameter value is successfully read, the first target unit parameter value is taken as the final target unit parameter value, and the step of assigning values to the unit parameter variables is continued.

[0072] S212, if the first target unit parameter value is abnormal, reading a second target unit parameter value from the first fixed storage area of the internal memory and determining whether the second target unit parameter value is abnormal.

[0073] Specifically, if the first target unit parameter value is abnormal, the second target unit parameter value is read from the first fixed storage area of the internal memory, and it is determined whether the second target unit parameter value is abnormal.

[0074] S213, if the second target unit parameter value is normal, the second target unit parameter value is written into the first settable storage area in the internal memory, and the second target unit parameter value is read from the first settable storage area.

[0075] Specifically, if the second target unit parameter value is normal, the second target unit parameter value is written into the settable storage area in the internal memory, the second target unit parameter value is read from the second settable storage area, and the second target unit parameter value is taken as the final target unit parameter value, and the step of assigning the unit parameter variable is continued.

[0076] Optionally, if the second target unit parameter value is normal, the second target unit parameter value can also be written into the fixed storage area of the internal memory, and written into the settable storage area and the fixed storage area of the external memory, for updating the abnormal target unit parameter stored in each storage area.

[0077] Optionally, in step S220, the reading of the target unit parameter value stored in the second parameter storage area of the external memory comprises:

[0078] S221, the third target unit parameter value is read from the second settable storage area of the external memory, and it is determined whether the third target unit parameter value is abnormal.

[0079] Wherein, the third target unit parameter value is the target unit parameter value stored in the second settable storage area of the external memory; and the second target unit parameter value is the target unit parameter value stored in the second fixed storage area of the internal memory.

[0080] Specifically, the second parameter storage area of the external memory comprises: a second settable storage area and a second fixed storage area, and the reading priority of the second settable storage area is higher than that of the second fixed storage area. Therefore, the third target unit parameter value is read from the second settable storage area of the external memory first, and it is determined whether the third target unit parameter value is abnormal; if the third target unit parameter value is normal, it indicates that the third target unit parameter value is successfully read, and the third target unit parameter value is taken as the final target unit parameter value, and the step of assigning the unit parameter variable is continued.

[0081] S222, if the third target unit parameter value is abnormal, the fourth target unit parameter value is read from the second fixed storage area of the external memory, and it is determined whether the fourth target unit parameter value is abnormal.

[0082] Specifically, if the third target unit parameter value is abnormal, the fourth target unit parameter value is read from the second fixed storage area of the external storage, and it is determined whether the fourth target unit parameter value is abnormal.

[0083] S223, if the fourth target unit parameter value is normal, the fourth target unit parameter value is written into the second settable storage area in the external storage, and the fourth target unit parameter value is read from the second settable storage area.

[0084] Specifically, if the fourth target unit parameter value is normal, the fourth target unit parameter value is written into the settable storage area in the internal storage, the fourth target unit parameter value is read from the second settable storage area, and the fourth target unit parameter value is taken as the final target unit parameter value, and the step of assigning the unit parameter variable is continued.

[0085] In one specific example, the method of reading the target unit parameter value (including the first target unit parameter value to the fourth target unit parameter value) and determining whether the target unit parameter value is abnormal can be: reading the target unit parameter value for a preset number of times in succession, if the first target unit parameter value read each time is abnormal, finally considering that the target unit parameter value is abnormal; wherein the preset number is an integer greater than or equal to 1. Figure 2B is a flow chart of the determination method of the target unit parameter value. As shown in Figure 2B The determination method of the target unit parameter value is specifically: reading the target unit parameter value, based on the parameter package encapsulated by the target unit parameter value, and based on the verification algorithm, verifying the parameters contained in the parameter package to obtain a verification result. For example, the parameters Para[0]~Para[n] contained in the parameter package can include: header code, parameter page, unit model, unit information and verification formula.

[0086] If the verification results of all parameters are correct, the target unit parameter value is read again until a preset number of times are reached. If the target unit parameter value read each time is verified to be normal, it is finally considered that the target unit parameter value is normal. If the verification result of any parameter is incorrect, the verification is stopped, the target unit parameter value is read again until a preset number of times are reached, and if the target unit parameter value read for a preset number of times in succession is verified to be abnormal, it is finally considered that the target unit parameter value is abnormal.

[0087] In the parameter storage reading and writing process, a multi-dimensional verification mechanism of header code, page number, unit model, unit information and verification information is added to ensure the correctness of the data stored in the storage area in the reading and writing process of the unit parameter.

[0088] Embodiment Three

[0089] Figure 3AA flowchart of a method for initializing a unit parameter according to the third embodiment of the present application is provided, and the embodiment is further limited to the case where the first settable storage area and the first fixed storage area exist in the internal memory of the unit. As shown in Figure 3A the method comprises:

[0090] S310, reading a target unit parameter value stored in a first parameter storage area of the internal memory after the unit is powered on; wherein the first parameter storage area comprises a first settable storage area and a first fixed storage area; wherein the reading priority of the first settable storage area is higher than that of the first fixed storage area.

[0091] In the embodiment, the first parameter storage area exists in the internal memory, and the first parameter storage area comprises the first settable storage area and the first fixed storage area.

[0092] Specifically, after the unit is powered on, the control board in the unit runs an initialization function, so that the control board runs an internal storage mechanism to read the target unit parameter value stored in the first settable storage area or the first fixed storage area of the internal memory. Since the reading priority of the first settable storage area is higher than that of the first fixed storage area, the target unit parameter value stored in the first settable storage area is read first, and if the target unit parameter value is abnormal, the target unit parameter value stored in the first fixed storage area is read.

[0093] S320, if the target unit parameter value stored in the first parameter storage area is abnormal, reading a target unit parameter value stored in an initial storage area of the internal memory.

[0094] Specifically, it is determined whether the target unit parameter value read from the first parameter storage area of the internal memory is abnormal, and if normal, step S330 is performed. If abnormal, the control board remains in an initialization state, and the target unit parameter value stored in the initial storage area of the internal memory is read. If the target unit parameter value read from the initial storage area is abnormal, the initialization state is exited, and the unit reports a fault and does not run. If the target unit parameter value read from the initial storage area is normal, step S330 is performed.

[0095] Optionally, if the target unit parameter value read from the initial storage area is normal, the target unit parameter value can also be written into the settable storage area and the fixed storage area of the internal memory, for updating the abnormal target unit parameter stored in each storage area.

[0096] S330, assigning a unit running parameter based on the target unit parameter value.

[0097] S340, returning the unit running parameter to the host computer when a unit parameter query instruction of the host computer is received.

[0098] The technical scheme of the embodiment of the application comprises the following steps: after the unit is powered on, reading a target unit parameter value stored in a first parameter storage area of an internal memory; wherein the first parameter storage area comprises a first settable storage area and a first fixed storage area; wherein the reading priority of the first settable storage area is higher than the reading priority of the first fixed storage area; if the target unit parameter value stored in the first parameter storage area is abnormal, reading a target unit parameter value stored in an initial storage area of the internal memory; assigning a unit parameter variable based on the target unit parameter value to obtain a unit running parameter; and returning the unit running parameter to a host computer when a unit parameter query instruction of the host computer is received. By using the three-level parameter storage area of the internal memory and the corresponding three-level parameter storage mechanism, the problem that the unit parameter is easily disturbed during the parameter initialization process of the unit, the unit cannot be normally started or even a fault is caused due to the abnormal parameter, the accuracy of the unit running parameter during the parameter initialization process of the unit, the safety and reliability of the unit are improved, and the stable operation of the unit is ensured.

[0099] Optionally, in step S310, reading the target unit parameter value stored in the first parameter storage area of the internal memory comprises:

[0100] S311, reading a first target unit parameter value from the first settable storage area of the internal memory and determining whether the first target unit parameter value is abnormal;

[0101] S312, if the first target unit parameter value is abnormal, reading a second target unit parameter value from the first fixed storage area of the internal memory and determining whether the second target unit parameter value is abnormal;

[0102] S313, if the second target unit parameter value is normal, writing the second target unit parameter value into the first settable storage area of the internal memory and reading the second target unit parameter value from the first settable storage area.

[0103] Specifically, the specific execution process of steps S311 to S313 is basically the same as that of steps S211 to S213 in the second embodiment, and the application will not be repeated here.

[0104] Figure 3B is a flowchart of an example unit parameter initialization method. As shown in Figure 3BAs shown, in one specific example, after the unit is powered on, the target unit parameter value stored in the writable storage area of the internal memory is read, the parameter value abnormality determination mechanism is run, and it is determined whether the target unit parameter value read from the writable storage area is normal; if normal, the unit initialization process is performed to make the unit normally run. If abnormal, the target unit parameter value stored in the fixed storage area is read, the parameter value abnormality determination mechanism is run, and it is determined whether the target unit parameter value read from the first fixed storage area is normal.

[0105] If the target unit parameter value read from the fixed storage area is normal, the target unit parameter value is written into the first writable storage area in the internal memory, the step of reading the target unit parameter value from the writable storage area is re-executed, it is determined that the target unit parameter value read from the first writable storage area is normal, the unit initialization process is performed to make the unit normally run.

[0108] Figure 4 A flowchart of a unit parameter initialization method provided for Embodiment Four of the present application, which further limits the above-mentioned embodiments to the case where only the second writable storage area and the second fixed storage area exist in the external memory of the unit. As shown, the method comprises: Figure 4

[0109] S410, after the unit is powered on, reading the target unit parameter value stored in the second parameter storage area of the external memory; wherein the second parameter storage area comprises: a second writable storage area and a second fixed storage area; wherein the reading priority of the second writable storage area is higher than that of the second fixed storage area.

[0110] In this embodiment, the second parameter storage area exists in the external memory, and the second parameter storage area comprises: a second writable storage area and a second fixed storage area. ​

[0111] Specifically, after the unit is powered on, the control board in the unit runs an initialization function, so that the control board runs an external storage mechanism, reads the stored target unit parameter value from the second settable storage area or the second fixed storage area of the external storage. Since the read priority of the second settable storage area is higher than that of the second fixed storage area, i.e., the target unit parameter value stored in the second settable storage area of the external storage is read first, if the target unit parameter value is abnormal, the target unit parameter value stored in the second fixed storage area is read again.

[0112] S420, if the target unit parameter value stored in the second parameter storage area is abnormal, read the target unit parameter value stored in the initial storage area of the internal storage.

[0113] Specifically, it is judged whether the target unit parameter value read from the second parameter storage area of the external storage is abnormal, if normal, step S330 is executed. If abnormal, the control board remains in the initialization state, and the target unit parameter value stored in the initial storage area of the internal storage is read. If the target unit parameter value read from the initial storage area is abnormal, the initialization state is exited, and the unit reports a fault and does not run. If the target unit parameter value read from the initial storage area is normal, step S430 is executed.

[0114] Optionally, if the target unit parameter value read from the initial storage area is normal, the target unit parameter value can also be written into the settable storage area and the fixed storage area of the external storage, for updating the abnormal target unit parameter stored in each storage area.

[0115] S430, based on the target unit parameter value, the unit parameter variable is assigned to obtain a unit running parameter;

[0116] S440, when receiving the unit parameter query instruction of the host computer, the unit running parameter is returned to the host computer.

[0117] The technical scheme of the embodiment of the application comprises the following steps: after the unit is powered on, reading target unit parameter values stored in a second parameter storage area of an external memory; the second parameter storage area comprises a second settable storage area and a second fixed storage area; the reading priority of the second settable storage area is higher than that of the second fixed storage area; if the target unit parameter values stored in the second parameter storage area are abnormal, reading target unit parameter values stored in an initial storage area of an internal memory; assigning a unit parameter variable based on the target unit parameter values to obtain a unit operation parameter; and returning the unit operation parameter to a host computer when a unit parameter query instruction of the host computer is received. The three-level parameter storage area composed of the initial storage area of the internal memory and the second settable storage area and the second fixed storage area of the external memory and the corresponding three-level parameter storage mechanism solve the problem that the unit parameters are easily disturbed during the parameter initialization process, the unit cannot be normally started or even fails due to abnormal parameters, improve the accuracy of the unit operation parameters during the parameter initialization process of the unit, the safety and reliability of the unit, and ensure the stable operation of the unit.

[0118] Optionally, in step S420, reading target unit parameter values stored in a second parameter storage area of an external memory comprises:

[0119] S421, reading a third target unit parameter value from a second settable storage area of the external memory and determining whether the third target unit parameter value is abnormal;

[0120] S422, if the third target unit parameter value is abnormal, reading a fourth target unit parameter value from a second fixed storage area of the external memory and determining whether the fourth target unit parameter value is abnormal;

[0121] S423, if the fourth target unit parameter value is normal, writing the fourth target unit parameter value into the second settable storage area of the external memory and reading the fourth target unit parameter value from the second settable storage area.

[0122] Specifically, the specific execution process of steps S421 to S423 is basically the same as that of steps S221 to S223 in Embodiment Two, and the present embodiment will not be repeated here.
