However, during the operation of the centrifuge, there is a certain amount of vibration, which interferes with other equipment used in the determination of soil available boron, which is not conducive to the efficiency of the determination of soil available boron. Currently, the equipment carrying the centrifuge can only change the vertical position of the centrifuge, and cannot change the horizontal position of the centrifuge, which cannot meet the flexible use requirements. In addition, the current carrying equipment does not have good anti-vibration performance, and often vibrates during the operation of the centrifuge, which has a negative effect on the carrying equipment, and also reduces the service life of the carrying equipment, which is not conducive to the safe use of the carrying equipment.

However, the current control of absorbance, temperature of beaker and temperature of constant temperature drying box is only performed locally, which is not efficient and cannot monitor the absorbance, temperature of beaker and temperature of constant temperature drying box remotely.

[0035] This invention, by unscrewing the first lead screw, allows the motion stage to perform horizontal movement within the guide channel, and by unscrewing the second lead screw, allows the motion block to perform longitudinal movement on the motion stage. This enables planar movement of the centrifuge, greatly flexibly meeting application requirements. The introduction of vibration-damping devices effectively reduces the vibration effect of the centrifuge, eliminating and mitigating vibrations during centrifuge operation. This prevents significant vibrations during centrifuge operation from interfering with other equipment used in soil available boron determination. Prolonged vibrations from centrifuge operation reduce the service life of the supporting equipment, compromising its safe operation. The running motor pulls the first toothed disc... The first sprocket rotates, pulling the second sprocket to rotate. The second sprocket pulls the roller to rotate, which in turn pulls the first rotating disc to rotate. The first rotating disc, via a chain plate, pulls the second rotating disc to rotate, which in turn pulls the lead screw used for support to rotate. The lead screw used for support rotates, pulling the lifting cylinder to move downwards. The parallel lifting bars and strip-shaped openings guide the lifting cylinder. The lifting cylinder pulls the receiving plate downwards, allowing the casters to disengage from the moving opening and slowly support the equipment. The equipment is then driven to the centrifuge side via the handle. When no movement is needed, the motor can be rotated in the opposite direction to retract the casters into the moving opening, allowing the supporting equipment to move very conveniently and making it highly versatile. The photometer, infrared sensor one, and infrared sensor two transmit measurement information such as the absorbance of the filtrate, the temperature of the beaker, and the temperature of the constant temperature drying oven to the controller connected to them. The controller then transmits the measurement information to the flash memory for storage, thus enabling centralized and efficient unified processing of the measurement information. The controller also transmits the measurement information to a remote storage platform in the wireless network via a wireless module for storage. The remote storage platform also transmits the measurement information to a remote query platform for display, thus achieving the control effect of remote storage backup and remote query display.

[0036] This method effectively avoids the shortcomings of existing technologies, such as significant vibrations during centrifuge operation interfering with other equipment used in the determination of available boron in soil, reducing the efficiency of available boron determination, the inability of the equipment supporting the centrifuge to perform horizontal movements, the inability to meet flexible application requirements, the adverse effects of vibrations during centrifuge operation, and the long-term reduction of the service life of the supporting equipment, which is detrimental to its safe use. It also effectively avoids the inefficiency of controlling absorbance, beaker temperature, and constant temperature drying oven temperature locally in the determination of available boron in soil, and the inability to remotely monitor these parameters.

The off-site storage platform and the off-site query platform can be a PC or an industrial computer that is off-site and in the wireless network. The controller can be a single-chip microcomputer, an ARM chip or a PLC; the photometer, infrared sensor one and infrared sensor two respectively transmit the determination messages such as the absorbance of the filtrate, the temperature of the beaker and the temperature of the constant temperature drying oven to the controller connected thereto, and the controller further transmits the determination messages to the flash memory for storage, so that the determination messages can be centrally and efficiently disposed, and the controller further transmits the determination messages to the off-site storage platform in the wireless network for storage, and the off-site storage platform further transmits the determination messages to the off-site query platform for display, so that the off-site storage backup and off-site query display control effect can be achieved.

[0049] The controller of the front platform also transmits the measurement message to the off-site storage platform in the wireless network via the wireless module, and the off-site storage platform also transmits the measurement message to the specific method displayed in the off-site query platform, which includes:

[0050] In the smart phone, the off-site query platform, the wireless network, the off-site storage platform and the front platform, the wireless network is used to construct a wireless channel between the smart phone and the off-site query platform, the wireless network is used to construct a wireless channel between the off-site query platform and the off-site storage platform, and the wireless network is also used to construct a wireless channel between the off-site storage platform and the front platform. The user can enter the identification code of the front platform via the smart phone dialog box, and the dialog box of the smart phone transmits the command for off-site operation with the identification code to the off-site query platform after obtaining the identification code. The off-site query platform transmits the command for off-site operation to the off-site storage platform, and the off-site storage platform performs corresponding processing on the command containing the identification code of the front platform after obtaining the command, until the off-site operation of the measurement message is achieved.

[0051] The off-site storage platform can be a platform for achieving off-site operation of all measurement messages, such as obtaining the command for measurement message of the front platform according to the mode set in advance by the off-site query platform, transmitting the command to the front platform, and making the front platform transmit the measurement message.

[0052] The front platform can transmit the measurement message to the off-site storage platform in real time with the help of the wireless network, and can transmit the message according to the protocol set in advance.

[0053] The controller of the front platform also transmits the measurement message to the off-site storage platform in the wireless network via the wireless module, and the off-site storage platform also transmits the measurement message to the specific method displayed in the off-site query platform, which includes:

[0054] Here the number of smart phones, off-site query platforms, wireless networks, off-site storage platforms and front platforms is not restricted.

[0055] Step 1: After obtaining the identification code representing the mark of the front platform via the off-site query platform, the front platform corresponding to the identification code constructs a channel;

[0056] In the present application, the remote saving platform can obtain a command for remote operation of the measurement message from the remote query platform, and the command has the identification code information of the foreground platform obtained by the remote query platform through the dialog box; after obtaining the identification code, the remote saving platform constructs a wireless channel with the foreground platform corresponding to the identification code; the identification code of the foreground platform can be used to represent the mark of the foreground platform; the foreground platform corresponding to the identification code constructs a wireless channel, which can construct an executable message transmission channel, for example, the remote saving platform can call the port set on the foreground platform to obtain the measurement message from the foreground platform; under the condition that the foreground platform accesses the remote saving platform, the remote operation of the measurement message is achieved by receiving the command content with the vehicle network identification code transmitted by the remote query platform, and the operation complexity of the measurement message is reduced.

[0057] Step 2: obtaining the command for requesting the measurement message on the foreground platform through the mode set in advance according to the remote query platform, transmitting the command to the foreground platform, and making the foreground platform transmit the measurement message;

[0058] In the present application, the smart phone listens to whether the dialog box is activated to obtain the measurement message command on the foreground platform through the mode set in advance; if the command is listened to, the command is transmitted to the remote query platform; the remote query platform forms a command for obtaining the measurement message on the foreground platform through the mode set in advance, and transmits the command to the remote saving platform; after receiving the command, the remote saving platform transmits the command to the foreground platform to make the foreground platform transmit the measurement message to the remote saving platform.

[0059] In detail, the command for requesting the measurement message on the foreground platform through the mode set in advance is used to request to identify the set measurement message on the foreground platform through the mode set in advance and obtain it. For example, the measurement message can be obtained by identifying the set measurement message on the foreground platform through the query measurement message pointer mode; or it can be obtained by identifying the set measurement message on the foreground platform through the identification pointer mode.

[0060] Further, transmitting the command to the foreground platform to make the foreground platform transmit the measurement message according to the remote query platform receiving the command for requesting the measurement message on the foreground platform through the mode set in advance includes: obtaining the pointer of the measurement message on the foreground platform through the remote query platform according to the command for requesting the measurement message on the foreground platform through the mode set in advance; transmitting the command for obtaining the measurement message pointed by the pointer to the foreground platform to make the foreground platform search for the measurement message pointed by the pointer; and receiving the measurement message transmitted by the foreground platform.

[0061] In the present application, after receiving the command for obtaining the required measurement message on the foreground platform by the prior setting mode through the remote query platform, the pointer of the measurement message set on the foreground platform can be obtained through the remote query platform, which is identified by the prior setting mode. After obtaining the pointer of the set measurement message, the command for obtaining the set measurement message is transmitted to the foreground platform, so that the foreground platform searches for the set measurement message under the pointer, and the searched measurement message is transmitted to the remote storage platform. Then, the remote storage platform receives the set measurement message transmitted by the foreground platform.

[0062] Further, according to the command for obtaining the required measurement message on the foreground platform by the prior setting mode through the remote query platform, the pointer of the measurement message on the foreground platform obtained through the remote query platform has: according to the command for obtaining the required measurement message on the foreground platform by the query mode through the remote query platform, the pointer of all the measurement messages stored in the foreground platform is given to the remote query platform; after detecting that a pointer in the stored pointer of all the measurement messages is identified, the identified pointer is obtained through the remote query platform.

[0063] The user can activate the command for obtaining the measurement message on the foreground platform by the query mode through the dialog box on the remote query platform. After receiving the command through the remote query platform, the remote storage platform can give the pointer of all the measurement messages stored in the foreground platform to the remote query platform, because the remote storage platform has established a channel with the foreground platform. That is, the pointer value of all the measurement messages under the flash memory of the foreground platform is transmitted to the remote query platform. With the help of the remote query platform, all the measurement messages under the flash memory can be displayed in the form of a measurement message list in the dialog box, and each measurement message can be corresponding to its corresponding pointer. After the user selects a measurement message pointer through the dialog box, the selected measurement message is identified, the pointer value of the measurement message is transmitted to the remote query platform, the remote storage platform can obtain the selected pointer through the remote query platform, then form a command for obtaining the selected measurement message, and transmit the request to the identified foreground platform.

[0064] Further, according to the command for obtaining the required measurement message on the foreground platform by the prior setting mode through the remote query platform, the pointer of the measurement message on the foreground platform obtained through the remote query platform has: according to the command for obtaining the required measurement message on the foreground platform by the identification pointer mode through the remote query platform, the destination identification pointer recorded through the remote query platform is obtained.

[0065] The user can activate the command for identifying the pointer of the measurement message on the foreground platform via the dialogue box on the remote query platform, then the remote storage platform can obtain the pointer of the set measurement message via the remote query platform after the remote storage platform receives the command, form the command for obtaining the set measurement message, and transmit the command to the identified foreground platform.

[0066] Via the above achieving method, the mode of the remote measurement message is facilitated, and the efficiency of the remote operation is improved.

[0067] Further, after the channel is constructed between the foreground platform corresponding to the identification code, the controller of the foreground platform further transmits the measurement message to the remote storage platform in the wireless network via the wireless module, and the remote storage platform further transmits the measurement message to the specific method displayed on the remote query platform, and the method further comprises: transmitting the preset operation command to the foreground platform according to the message for transmitting the preset operation command to the foreground platform received by the remote query platform, so that the foreground platform executes the preset operation command.

[0068] In the present application, after the channel is constructed between the remote storage platform and the foreground platform corresponding to the identification code, the remote query platform can further receive the request for transmitting the preset operation command to the foreground platform activated via the dialogue box, transmit the command to the remote storage platform, form the message for executing the preset control on the foreground platform after the remote storage platform receives the command, so that the foreground platform executes the corresponding operation according to the above preset operation command, and the preset operation command is preset, and the remote operation can be executed on the kernel of the foreground platform or the program on the foreground platform.

[0069] Step 3: transmitting the measurement message to the remote query platform.

[0070] In the present application, after the pointer of the target measurement message on the foreground platform is identified, the foreground platform can transmit the data of the measurement message pointed by the target pointer to the remote storage platform, the remote storage platform transmits the message to the remote query platform, and the content of the measurement message is displayed with the assistance of the remote query platform.

[0071] The application achieves the operation of the measuring message of a foreground platform via the mode of the remote place by the following steps: after obtaining the identification code for representing the label of the foreground platform via the platform for querying in the remote place, the channel of the foreground platform corresponding to the identification code is constructed; then, according to the command for obtaining the measuring message of the foreground platform via the mode of the presetting, the command is transmitted to the foreground platform to make the foreground platform transmit the measuring message; after the channel of the foreground platform corresponding to the identification code is constructed, according to the message for transmitting the preset operation command to the foreground platform via the platform for querying in the remote place, the preset operation command is transmitted to the foreground platform to make the foreground platform execute the preset operation command, thus the operation of the measuring message via the preset command is achieved.
