The disadvantages are also obvious, including: a. There is no strict correspondence between the random code and the equipment, and the manufacturer cannot determine whether the corresponding information between the random code and the unit provided by the engineering personnel is true, which makes there are loopholes in the control, that is, the engineering personnel may Only provide the barcode information of one device for filing, but use the random codes of multiple devices multiple times to ask for passwords, and then modify the manufacturer parameters of multiple devices; b. For a non-standard device that has been filed, repeated filing is meaningless Large, but increases the workload and complicates the process
[0006] It can be seen that the access control of the manufacturer's parameters in the equipment in the prior art cannot be simple and effective, and it is easy to generate loopholes and lead to the failure of the control force

Embodiment Construction
[0037] Considering the deficiencies in the prior art regarding the access authority control of the manufacturer's parameters in the equipment, the present invention contemplates a method of generating a password for the manufacturer's parameters using a device barcode corresponding to the equipment one-to-one to overcome the existing problems in the prior art. question.
[0038] Since the manufacturer will assign a unique barcode to each device, so as to control the area distribution of products and facilitate after-sales service management, etc., the barcode is in one-to-one correspondence with the device, and there will be no duplication. In addition, because the barcode of the equipment has generally abandoned the form of paper media pasted on the surface of the product, it is stored in the equipment controller, such as the EEPROM memory chip burned into the controller before leaving the factory, so it is read by the controller. Taking the barcode and performing calculation...

The invention relates to a control method for access to manufacturer parameters in equipment. The control method comprises the following steps: S10, an equipment controller reads an equipment barcode; S20, the equipment controller obtains a manufacturer parameter password through the equipment barcode and calculation according to a preset password rule; and S30, the equipment controller controls manufacturer parameter access permissions through the manufacturer parameter password. The control method provided by the invention has the advantages that an equipment manufacturer can simply and effectively control the manufacturer parameter access permissions, that is, a correct access password must be input before the access to the manufacturer parameters, the password for each equipment must be generated through the exclusive barcode of the equipment, and the access password is not provided by the manufacturer until the barcode is recorded at the manufacturer.
Description
technical field [0001] The invention relates to a control method for accessing factory parameters in equipment. Background technique [0002] For large-scale equipment such as commercial air-conditioning units, due to the complexity of the installation environment and matching methods, it is usually necessary to reserve some adjustable parameters. Most of the parameters are highly professional and may be related to personal safety or equipment life, so only manufacturers and authorized professionals are allowed to set them. Therefore, these parameters are often referred to as "factory parameters". In most cases, the manufacturer's parameters are directly using the factory default values, and there is no need to adjust them during installation and commissioning. However, in special cases, such as unreasonable selection by the engineering company or the harsh installation environment, it is necessary to make appropriate adjustments to the manufacturer's parameters in order t...
