Detailed ways

In order to make the purpose, technical solutions and advantages of this application clearer, the technical solutions in this application will be clearly and completely described below in conjunction with the accompanying drawings in this application. Obviously, the described embodiments are part of the embodiments of this application , but not all examples. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of this application.

The terms "first", "second" and the like in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific sequence or sequence. In addition, "and/or" in the specification and claims represents at least one of the connected objects.

In the prior art, as shown in Figure 2, the arrangement specialist is used to control the production of the mixing plant using the host computer in the control room, or as shown in Figure 3, through Enterprise Resource Planning (Enterprise Resource Planning, ERP) or application (Application, APP) Send instructions to the customized upper computer system to indirectly control the production of the mixing station.

Neither of the two methods can realize the remote control of the on-site equipment of the mixing plant, and the intelligence level is low and the cost is high.

For example, for a cement mixing plant, it is necessary to start manual equipment in advance. For an asphalt mixing plant, it is even necessary to go to the site to start the heat transfer oil system several hours in advance, and wait for the dust collector to reach the shutdown condition after the production is completed before leaving the site.

Among them, when the indirect control method shown in Figure 3 is used, the host computer must be online all the time; the device must be kept running if it needs to be manually turned on; faulty nodes are added; and the cost of purchasing dedicated servers and recruiting ERP-related personnel is higher.

The following describes the remote control method, control terminal, remote terminal and remote control system of the mixing plant of the mixing plant of the present application with reference to FIG. 1 , FIG. 4 to FIG. 12 .

The remote control method of the mixing station provided by the embodiment of the present application, as shown in FIG. 1 , the method includes step 110, step 120, step 130, step 140 and step 150.

The execution subject of the method is the control terminal, which may be a controller at the site of the mixing station; or a server electrically or communicatively connected with the manual equipment of the mixing station.

The remote control method of the mixing station provided by the embodiment of the present application, as shown in FIG. 1 , can realize the remote control of the field equipment of the mixing station.

It should be noted that, in the remote control method of the mixing station provided in the embodiment of the present application, the mixing station is provided with an intelligent switch for controlling power-on or power-off of manual equipment.

The intelligent switch can be connected with the manual equipment on the site of the mixing station to realize the remote control of the manual equipment on the site of the mixing station.

For example, a mixing station is equipped with an intelligent switch group, which includes multiple intelligent switches, and each intelligent switch controls different manual equipment. The intelligent switch for the start and stop of the Programmable Logic Controller (PLC), the intelligent switch for controlling the start and stop of the video surveillance system, and the intelligent switch for controlling the start and stop of other production manual equipment.

For example, for an asphalt mixing plant, a smart switch is connected to the heat transfer oil system, enabling the remote start of the heat transfer oil system a few hours before production starts.

On the other hand, as a control node, the intelligent switch improves the availability of the system.

Step 110, receiving the production preparation instruction sent by the remote end.

It can be understood that the remote end can be an intelligent mobile terminal such as a mobile phone or a personal computer (Personal Computer, PC).

The remote terminal and the control terminal of the mixing station can be connected through wireless communication to realize remote control.

For example, the control terminal is connected to the remote terminal through a cloud platform, a virtual private network (Virtual Private Network, VPN) or a global positioning system (Global Position System, GPS).

After the connection between the remote terminal and the control terminal is successful, the control terminal receives the production preparation instruction sent by the remote terminal.

By canceling or closing the upper computer in the control room, the remote terminal in this application can be used as a lightweight upper computer to realize remote control of the field equipment of the mixing plant.

Step 120, in response to the production preparation instruction, control the intelligent switch to be turned on to power on the manual device.

It can be understood that after receiving the production preparation instruction, the control terminal can change the on-off state of the smart switch according to the production preparation instruction.

The production preparation command can be used to turn on multiple smart switches at the same time, or to turn on multiple smart switches successively, or to couple the open and close states of multiple smart switches.

For example, the manual equipment may be production-type manual equipment, including heat transfer oil systems and the like. The production preparation command is used to turn on the intelligent switch used to control the power on and off of the heat transfer oil system a few hours before the start of production.

In some embodiments, there may be multiple smart switches, which are respectively connected to multiple manual devices, and the information carried in the production preparation instruction may be a combination of on-off states of multiple smart switches.

In other words, the production preparation instruction can be used to control some of the multiple smart switches to be turned on.

The production preparation instruction can include a combination of on and off states of multiple smart switches;

Alternatively, the production preparation command can be used to invoke the combination of on-off states of multiple intelligent switches preset in the control terminal.

It should be noted that the field equipment of the mixing plant and the control terminal can be connected directly or indirectly.

Smart switches can also be connected to manual equipment, which can include: production-type manual equipment and lower computers, or manual equipment can include: production-type manual equipment, lower computers, and video surveillance systems.

Step 130, when it is determined that the manual device is powered on, send feedback information to the remote end.

It can be understood that, after executing the production preparation instruction, the control terminal provides feedback information to the remote terminal after confirming that the manual device is powered on, and feeds back the execution status of the production preparation instruction.

When the production preparation instruction is used to control the opening of some of the multiple intelligent switches, the feedback information can be the actual opening of the intelligent switch, or whether the production preparation instruction is executed.

Step 140, receiving the production instruction sent by the remote end based on the feedback information.

It should be noted that due to the particularity of the production process of the mixing plant, the production process information is required to complete the production process.

The production instruction can include the production process information of the mixing station;

The production process information may include production time information and equipment working condition information, so as to control the mixing station to start production according to the production process information, and stop production after the production is completed.

Step 150, in response to the production instruction, the lower computer of the mixing station controls the mixing station to produce according to the production process information.

It can be understood that the remote end can use the information carried in the production order to control the work of the mixing station through the lower computer of the mixing station. Wherein, the lower computer can be at least one of PLC single-chip microcomputers.

The control terminal can be connected with the smart switch and the lower computer through WIFI, Bluetooth or ZIGBEE, which can act as a bridge and interlock.

The information carried in the production order can make the lower computer control the mixing station to start production according to the production process information, and stop production after the production is completed.

It should be noted that the production instruction may include at least one of ingredient ratio information, processing time, and the opening sequence of the production equipment in the production process of the mixing station;

Alternatively, the production instruction can also be used to run the preset production program or control algorithm on the control terminal;

Alternatively, the production instruction can also be used to make the preset production program or control algorithm run on other equipment on the site of the mixing plant.

Due to the particularity of the production process of the mixing plant, the opening and closing of the on-site equipment of the mixing plant needs to follow a certain order.

In one embodiment, the production instruction can be controlled by the PLC of the asphalt mixing plant, and the motors can be turned off in the order of recycled material variable frequency motor, flat belt motor, inclined belt motor, elevator motor, drying drum feeding belt motor and drying drum motor .

According to the remote control method of the mixing plant provided by this application, the particularity of the production process of the mixing plant is fully considered, and the manual equipment is remotely controlled to be powered on through the remote terminal and the smart switch, and the remote terminal is used to replace the upper computer in the control room. And the lower computer remotely controls the production process of the mixing station, realizes the remote control of the mixing station, improves the intelligence level of the production process, and saves electric energy.

In some embodiments of the present application, as shown in FIG. 4, in step 120, controlling the smart switch to turn on includes:

Step 121, when the intelligent switch includes a first sub-switch, and the manual device includes a video monitoring system, control the first sub-switch corresponding to the video monitoring system to be turned on, the video monitoring system is used to send image information to the remote end, the first The sub-switch is an intelligent switch corresponding to the video surveillance system;

and / or,

Step 122, when the intelligent switch includes a second sub-switch, and the manual device includes a lower computer, control the second sub-switch corresponding to the lower computer to turn on, so that the lower computer is powered on, and the second sub-switch is the second sub-switch corresponding to the lower computer. smart switch;

and / or,

Step 123, when the smart switch includes a third sub-switch and the manual device includes a production-type manual device, control the third sub-switch corresponding to the production-type manual device to be turned on, so as to power on the production-type manual device.

It should be noted that, in actual execution, one or more of steps 121 - 123 may be selected for execution, and steps 121 - 123 do not indicate the order of execution.

It can be understood that there can be multiple intelligent switches, which can be connected to at least one of the production-type manual equipment of the video monitoring system, the lower computer and the mixing station, so as to realize the fine control of the mixing station.

Wherein, the manual equipment of the mixing station is not limited to one kind of manual equipment. Taking the asphalt mixing plant as an example, the manual equipment of the mixing plant can include heat transfer oil system and dust collector. When the mixing station is another mixing station, there may be differences in the manual equipment of the mixing station.

After the intelligent switch turns on the video monitoring system on site of the mixing plant, the image information collected by the camera can assist the user in remote control of the mixing plant.

Wherein, the image information may be at least one of an RGB image, a grayscale image and a depth image of the production site collected by the camera.

It may also be the image information after the video surveillance system performs video image processing based on the image collected by the camera, such as at least one of grayscale, color space conversion, denoising, image enhancement, labeling, and compression.

In the above embodiments, the fine control of the mixing station is realized through the intelligent switch.

In some embodiments of the present application, as shown in FIG. 5 , after step 150 , the method further includes step 510 and step 520 .

Step 510, receiving the working condition information of the mixing plant fed back by the lower computer.

It should be noted that the working condition information can be data collected at the production site;

Or, the result after data analysis and processing;

Or, the result of converting between values, tables and images;

Of course, a combination of the above situations is also possible.

After the lower computer receives the working condition information, it can send the working condition information to the control terminal.

Step 520, sending the working condition information to the remote end.

Correspondingly, after receiving the working condition information fed back by the lower computer, the control terminal can directly send the data collected at the production site to the remote terminal;

Alternatively, the processed data collected at the production site is sent to the remote end.

The working condition information may be a digital signal collected according to process requirements.

For example, in an asphalt mixing plant, the working condition information can be the calculation and measurement information of different material weighing;

Alternatively, the operating parameters of various pumps used for transportation, stirring and heating and holding;

Alternatively, various analog signals, such as at least one of temperature and pressure.

It should be noted that the control terminal can only play the role of forwarding, and can also process the data collected at the production site.

In the above embodiments, the real-time acquisition of the production site information by the remote terminal is realized by feeding back the on-site working condition information to the remote terminal.

In some embodiments of the present application, as shown in FIG. 6 , after step 150 , the method further includes step 610 , step 620 and step 630 .

Step 610, receiving a production stop instruction sent by the remote end.

Step 620, in response to the production stop instruction, control the mixing station to switch to the production stop state through the lower computer;

Step 630, controlling the smart switch to be turned off, so that the manual device is powered off.

It should be noted that after the production is completed, the remote terminal sends a production stop command to the control terminal, and the control terminal controls the mixing plant to switch to the production stop state through the lower computer based on the production stop command, such as controlling the reset of each equipment of the mixing plant. Then, control the smart switch to turn off, so that the manual device is powered off.

In addition, due to the particularity of the production process of the mixing plant, the manual equipment and lower computers on the site of the mixing plant need to be shut down in a certain order.

For example, a stop production command can be used to delay the shutdown of a smart switch connected to a dust collector after production is complete.

In one embodiment, the production stop instruction is used to control the weighing equipment, batching equipment, feeding equipment, heating equipment, finished product silo equipment and dust removal equipment of the asphalt mixing plant to shut down in a predetermined order through an intelligent switch.

In the above embodiment, the manual equipment of the mixing station is controlled to be closed sequentially through the intelligent switch, which ensures the safety of production.

In one embodiment, as shown in Fig. 8, the asphalt mixing plant is provided with multiple intelligent switches, forming an intelligent switch group.

The server is connected to the remote terminal through the cloud platform, VPN or GPS; through the LAN switch and the central control terminal, it is connected to the intelligent switch group through ZIGBEE; through the LAN switch, it is connected to the PLC through WIFI.

It should be noted that the intelligent switch group controls the start and stop of manual equipment, and the PLC executes the production process to control the start and stop of production.

The intelligent switch group, the central control terminal and the control terminal can all be used as control nodes to improve the availability of the system.

The smart switch group includes a first smart switch, a second smart switch and a third smart switch. The first intelligent switch communicates with the heat transfer oil system, the second intelligent switch communicates with the PLC, and the third intelligent switch communicates with the video monitoring system.

Among them, the first, second and third are to distinguish the types of smart switches, and do not mean that the respective quantities are single, nor does it mean the opening and closing sequence of the three.

As a lightweight upper computer, the remote terminal can realize the functions of managing ratio, issuing instructions, displaying working conditions and recording reports.

The PLC is connected to the cold hopper and belt conveyor of the mixing station, and the speed can be controlled by controlling the frequency converter, thereby controlling the production cycle.

PLC can realize the instrument reset, parameter setting, scale calibration function, and can also detect instrument failure and alarm. In this way, all motors, cylinders and external equipment can be controlled according to the control logic, and fault points can be collected and precise alarms can be realized.

At the same time, PLC can realize the interlocking of mixing plant equipment. For example, for asphalt mixing plant, only one of "asphalt batching pump forward rotation" and "asphalt batching pump reverse rotation" can be started at the same time, and the two need to be interlocked with each other.

As shown in Figure 8, after the user opens the remote terminal, the control terminal is connected to the remote terminal, and if the shared lock fails to be obtained, it waits and refreshes the display lock status.

After successfully obtaining the shared lock, the remote terminal sends a production preparation instruction to the control terminal, and turns on the first intelligent switch, the second intelligent switch, the third intelligent switch and other manual equipment intelligent switches to prepare for production.

The control end confirms that the production preparation instruction has been executed, indicating that the production conditions are met, and then sends feedback information to the remote end.

After receiving the feedback information, the remote end sends production instructions to the control end to execute the production process and control the start and stop of production.

After receiving the production instructions, the control terminal forwards the production tasks and ratios and other production instructions to the PLC, and controls the PLC to start, execute and stop the production tasks according to the process.

For example, due to the particularity of the production process of the mixing plant, the starting sequence of the motors in the main building is carried out in the order of the vibrating screen motor, the stone hoist motor, the drying cylinder motor, the aggregate belt motor, the inclined belt, the flat belt motor and the cold material frequency conversion motor.

When the equipment is working, the current working condition information can be obtained through the PLC, and real-time image information can also be obtained with the help of the camera in the video monitoring system.

The control terminal forwards the working condition information to the remote terminal, and the video monitoring system sends the image information to the remote terminal, and an interface can be set on the remote terminal to integrate the working condition information and image information.

In the production process, the smart switch can be used to start and stop some electrical equipment; the control end can realize resource interlocking, control the smart switch, receive and forward production instructions and working conditions and other functions; the remote end can issue instructions, manage tasks, Recipe and other production data.

Users can monitor the production site image and the completion of production tasks in real time at the remote end.

When a fault is found, the user can send instructions to the control terminal based on the working condition information, and adjust and process through the intelligent switch group and PLC;

Alternatively, the intelligent switch group and PLC control equipment can be used to assist on-site staff in troubleshooting. After the cause of the fault is clarified, the intelligent switch group and PLC can be used to adjust and deal with it.

When the production is completed, the user can send a stop production command to the control terminal.

When it is confirmed that the PLC is in the stop production state, the control terminal sends a shutdown command to the intelligent switch group based on the stop production command to shut down the manual equipment and the PLC.

Finally, complete this production task.

Of course, the above steps can be repeated.

The embodiment of the present application also provides a remote control method for a mixing station. The mixing station is equipped with an intelligent switch for controlling the power on or off of manual equipment, as shown in FIG. 9 , including

It should be noted that, in this embodiment of the application, the manual equipment of the mixing station is equipped with an intelligent switch.

The intelligent switch can be connected with the manual equipment on the site of the mixing station to realize the remote control of the on-site equipment of the mixing station.

For example, the smart switch is connected with the heat transfer oil system to realize the remote start of the heat transfer oil system a few hours before the production starts.

Step 910, sending a production preparation instruction to the control terminal of the mixing station, the production preparation instruction is used to instruct the control terminal to control the intelligent switch to be turned on so as to power on the manual equipment.

The remote terminal and the control terminal can be connected through wireless communication to realize remote control.

For example, the control terminal is connected to the remote terminal through a cloud platform, VPN or GPS.

It can be understood that the production preparation instruction can be used to instruct the control terminal to change the on-off state of the smart switch.

For example, a production preparation command could be used to cause a smart switch connected to a heat transfer oil system to turn on a few hours before production begins.

In some embodiments, there may be multiple smart switches connected to multiple devices respectively, and the information carried in the production preparation instruction may be a combination of on-off states of multiple smart switches.

Step 920, receiving feedback information sent by the control terminal, where the feedback information is information sent by the control terminal when it is determined that the manual device is powered on.

It can be understood that, after executing the production preparation instruction, the control end provides feedback information to the remote end to feed back the execution status of the production preparation instruction.

When the production preparation instruction can be used to control the opening of some of the multiple intelligent switches, the feedback information can be the actual opening of the intelligent switch, or whether the production preparation instruction is fully executed.

Step 930: Send a production instruction to the control terminal in response to the feedback information.

The production instruction includes the production process information of the mixing station, and the production instruction is used to instruct the control terminal to control the mixing station to produce according to the production process information through the lower computer of the mixing station.

The production instruction can carry the production process information of the mixing station;

The production process information may include production time information, so as to control the mixing station to stop production according to the production process.

It can be understood that the remote end can use the information carried in the production order to control the production manual equipment of the mixing station through the lower computer of the mixing station. Wherein, the lower computer can be at least one of PLC and single-chip microcomputer.

The information carried by the production order can make the lower computer control the mixing station to start and stop production according to the production process.
