Product numbers are defined for the spray controllers with the spray control function, all parameters (the parameters comprise attribute parameters, event parameters and service parameters) corresponding to the spray controllers with the product numbers are combined, and a relatively complete parameter library is established. For the spray controller, as long as the definition of the attribute parameters is clear, the definition of the event parameters and the service parameters is clear naturally, because the event parameters are reported when faults are detected, and the parameters carried in the service parameters are all different attribute functions.
Table 4 shows the comparison of the properties of the spray controllers, and as shown in table 4, the product types of the spray controllers with the spray control function defined by the platform layer include the spray controllers with the product numbers and the parameters corresponding to the spray controllers with the spray control function. When the object model parameters of a spray controller with a certain product number are defined, the product parameters of the spray controller can be directly selected from a parameter library corresponding to the product type of the spray controller, if the product number spray controller has parameters which are not in the parameter library corresponding to the product type of the spray controller, the self-defined parameters can be added in the product number spray controller, or the parameters can be added in the parameter library corresponding to the product type of the spray controller, and then the parameters are checked under the product number spray controller. And converting the data into standard parameters defined by the object model according to the corresponding communication protocol, thereby realizing the unification of different product parameters.
Table 4 shows the comparison of spray controller attributes
For the common parameters of all the spray controllers with the product numbers, such as the switch of the spray controller, because the corresponding key value range and the corresponding value of the key in the key pair of the spray controllers with different product types may be different, for example, 0 in the spray controller with the product type 1 indicates shutdown, 1 indicates startup, and 1 in the spray controller with the product type 3 indicates shutdown, and 0 indicates startup. If the key value pair is directly used without standardization, misunderstanding is easily caused, and whether the parts from 0 to 1 to the bottom are turned on or off is judged according to the product model of the spray controller. In this embodiment, object model standardization is performed on the switch attribute, and 1 is uniformly used to indicate power on and 0 indicates power off. In order to facilitate the actual analysis, the platform development is performed at the same time, and the corresponding content is only required to be displayed according to the defined attribute value, regardless of the specific model of the equipment.
By the definition of the object model, the access standard of the product type of the same hardware device is standardized, the access to the hardware device is simpler, and a hardware developer only needs to develop a hardware analysis program according to the specification, so that the standardized access of the hardware is realized. Meanwhile, the data docking of the basic service function of the application software is also established, the upper-layer application software can be developed according to the interface document defined by the object model, the data docking of the upper-layer application software can be done, aiming at the public attribute (such as a switch state), the attribute field can be directly called, and the core service function is realized without considering which product model is in particular; for the unique attribute (such as voltage and current) of the hardware device, if the associated service function is to be realized, whether the attribute exists in the database corresponding to the product type of the hardware device or not needs to be judged through the product number index, so that different strategies are adopted to realize the standardization of hardware and software.
The object model simultaneously supports a third party application platform for data docking, and the third party application platform can call an object model data interface to acquire or control the state of the single device. The product object model supports version management, object model versions of products can be switched in the dimension of the project, only one object model version can exist in the same project, and if an old version object model is used before, a third party application platform can default to select the old version object model when registering equipment in a platform layer, so that the third party application platform is ensured to be updated without updating the object model version. If the object model version of the product in the project needs to be updated, selecting the product number, and directly switching the object model version to the corresponding version.
The embodiment supports the modification of the attribute names of the users in the dimension of the equipment, and is convenient for the users to distinguish the physical spaces corresponding to the attribute association functions. For example, in remote expansion control of a spray controller, a network I/O module capable of networking is used to generate a dry-contact signal to control spraying, and one network I/O controller on the market can generate several paths of dry-contact signals to control several motors. Since the names of the device properties are fixed throughout the object model definition, the property names displayed for all devices of the same object model version are the same. It is therefore desirable to provide the ability to modify the default attribute names to label each path of motors, and to distinguish which motor is the particular motor that each path controls.
In the embodiment, after the user registers the equipment, the attribute name can be modified in the equipment dimension according to the actual hardware wiring and delivery conditions on site. The table 5 is a correspondence between the positions and the names of the devices, as shown in the table 5, the "1 st path switch state" can be modified into the "southeast area spray switch state", so that a software developer or an end user does not need to memorize or search which area the first path switch state controls to spray, and the software developer or the end user does not need to customize development for projects or the software can realize more humanized butt joint and use by not modifying or modifying the first path switch state into the "unused" for other paths which are not actually used.
| Sequence number | Default attribute name | JSON field | Attribute name after device modification in |
| 1 | 1 st switch state | switch_state_1 | Southeast region spray switch state |
| 2 | 2 nd switch state | switch_state_2 | Northwest region spray switch state |
| 3 | 3 rd switch state | switch_state_3 | Status/unused 3 rd switch |
| 4 | 4 th switch state | switch_state_4 | Status/unused of 4 th switch |
