Referring to fig. 1, fig. 1 is a method for controlling device parameter modification according to the present application, the method including:
101. and when the access equipment is detected, requesting the identification algorithm and the identification library of the access equipment from the cloud.
In the embodiment of the invention, when the cloud electrically operated valve detects the access device, the cloud electrically operated valve requests the identification algorithm and the identification library of the access device from the cloud, the access device is a sub device (also called as a substation device) for accessing the cloud electrically operated valve, the cloud electrically operated valve can provide an RS485 interface, can access all RS485 serial port devices, and is used as a main device (also called as a main station device).
In the embodiment of the present invention, RS485 was a new balanced transmission standard approved by the american Electronic Industries Association (EIA) in 1983. The wireless receiving device has the main advantages of long-distance link, longest length of 4000 feet, differential signal transmission, strong anti-interference capability, capability of connecting a plurality of receiving sub-devices with the same bus and the like. And the electrical attribute of the RS-485 bus is utilized, and the address is distributed and the equipment is identified by combining a software protocol.
In the embodiment of the invention, the cloud is a software platform adopting an application virtualization technology, and integrates multiple functions of software searching, downloading, using, managing, backing up and the like.
In the embodiment of the present invention, the recognition library is used for supporting the recognition algorithm. The identification algorithm and the identification library are issued to the cloud electric valve through the cloud end, and the identification rate can be continuously expanded under the condition that cloud end equipment is not upgraded. The participation process of the user is increased, the name and the model of the accessed serial port equipment can be selected, the identification range is narrowed, and the identification speed is improved.
Specifically, when the access device is connected to the cloud electric valve, the cloud electric valve identifies the connected device through the electric signal, reports the event to the cloud end, pushes the event to the APP to prompt a user that the device is connected, and please select the name and the model of the connected device.
Further, before the above-mentioned detecting the access device, requesting the cloud for the identification algorithm and the identification library of the access device, where the identification library is used to support the identification algorithm, the present invention further includes: counting the distribution condition of equipment parameters; and sequencing according to the equipment parameter distribution to form a priority identification algorithm.
In the embodiment of the present invention, the device parameter may be preset data used as a reference, and the device parameter includes a baud rate, a check bit, a data bit, a stop bit, a default address, a register address, and the like.
In the embodiment of the present invention, the baud rate is a rate of a single chip microcomputer or a computer during serial port communication, and refers to a change of a signal in a unit time after being modulated, that is, the number of times of carrier parameter changes in the unit time, for example, 240 characters are transmitted per second, each character format includes 10 bits (1 start bit, 1 stop bit, 8 data bits), the baud rate is 240Bd, and the bit rate is 10 bits × 240 bits/second — 2400 bps. For example, 240 binary bits are transmitted per second, with a baud rate of 240Bd and a bit rate of 240 bps. (but typically the modulation rate is greater than the baud rate, such as manchester encoding). Baud rate, which can be understood colloquially as how many symbols of data a device transmits (or receives) in one second. It is a measurement of the symbol transmission rate, 1 baud means that 1 symbol is transmitted per second (by different modulation methods, multiple bit information can be loaded on one symbol), and 1 bit per second means that 1 bit (bit) is transmitted per second. The unit "Baud" itself already represents the number of modulations per second, and is a common error in units of Baud per second (Baud per second).
In the embodiment of the present invention, the check bit is a data bit that can be considered as a special data bit, and the received data bit is generally determined by using a similar method to determine whether there is an error, and is generally a parity check, which is usually cancelled during the use process.
In the embodiment of the invention, the data bit is a data bit which is the most important data bit in each group of data transmitted by a modem on a line and contains corresponding control data, including start sending data and end data. Different numbers of data bits and end bits are typically specified for different communication environments. In the receiver process, data bits can be obtained in three ways, the first is obtained in advance by using an externally assisted data link (such as a mobile communication network); the second is that the stored message is used for realizing data stripping by utilizing the periodicity of the navigation message, and the method is invalid when the message is updated; the third method is to estimate the data bits using the integration result (or demodulation result) of the live tributary, thereby achieving data stripping.
In an embodiment of the present invention, the stop bit is a bit for marking the end of a character transmission. There are two states in common on the signal line, which can be distinguished by a logic 1 (high level) and a logic 0 (low level), respectively. The data line should remain in a logic high state while sending its idle. The stop bit is the last to mark the end of the run of a character, which corresponds to the state of a logic 1. The high level refers to a minimum input high level allowed by ensuring that the input of the logic gate is a high voltage among the logic levels, and when the input level is higher than the input high voltage, the input level is considered as a high level. In a digital logic circuit, a low level indicates 0, and a high level indicates 1. Generally, the low level is 0-2.25V and the high level is 3.5-5V.
In the embodiment of the present invention, the default address may be an address set in advance, or a fixed address.
In an embodiment of the present invention, the register address is a high-speed storage unit with limited storage capacity, which can be used to temporarily store instructions, data and addresses. The register is a component of the CPU, and because the register is in the CPU, the CPU has the fastest read-write speed and does not need IO transmission. But at the same time it has been decided that the number of such registers is very limited, to the extent that almost every store has its own name, and some have multiple names. The register mainly has the functions of: the data in the register may be subject to arithmetic and logical operations; the address stored in the register can be used to point to a certain location of the memory, i.e. addressing; can be used to read and write data to the peripheral equipment of the computer.
It should be noted that, the device priority identification algorithm is formed by summing up and sorting the statistical device parameter distribution, the baud rate, the check bit, the data bit, the stop bit, the default address and the register address which are commonly used by the statistical device.
Further, the above requesting, from the cloud, the identification algorithm and the identification library of the access device when the access device is detected includes:
when the cloud electrically operated valve detects an access device, sending a device access request to a cloud end, wherein the device access request comprises a recognition algorithm and recognition base request and a name and model acquisition request of the access device, the name and model acquisition request of the access device is used for requesting the name and model of the access device to a user, and the name and model of the access device are used for matching the recognition algorithm and recognition base of the access device.
Further, the device parameters include at least one of baud rate, check bit, data bit, stop bit, default address, and register address, the device parameter distribution of all devices is counted, and the device parameter distribution is sorted to form a priority identification algorithm, including:
and counting baud rates, check bits, data bits, stop bits, default addresses and register addresses of all the devices, and sequencing according to the counting result to form a priority identification algorithm.

And modifying the baud rate, the check bit, the data bit and the stop bit of the serial port of the bus in sequence through a traversal algorithm, sending an instruction to a traversal address, determining the correct baud rate, the check bit, the data bit, the stop bit and the equipment address according to whether a response exists, and determining the name and the model of the equipment according to the response content.

In the identification process, the APP interface and the cloud electric valve screen display the identification step and the current progress, so that a user can make a best use of the identification step and the current progress, and long-time waiting is avoided.
