Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below, and it is apparent that the described embodiments are a part of the embodiments of the present invention, but not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Example 1
As shown in fig. 1 and fig. 2, this embodiment 1 provides a method for sharing group data of a Lora-based hot-in-place regenerator, including: step S1, establishing a data sharing local area network of the construction unit; step S2, setting the data sharing equipment installed on one of the construction machine sets as a host machine and the data sharing equipment installed on the other construction machine sets as slave machines; step S3, each slave machine respectively collects the construction data of the corresponding construction machine set and sends the corresponding construction data to the host machine and the other slave machines; step S4, the host computer collects and analyzes the construction data to generate early warning information, and sends the collected and analyzed construction data and the early warning information to each slave computer; and step S5, each slave machine adjusts the construction process of the corresponding construction machine set according to the construction data and the early warning information after the summary analysis.
Specifically, each slave machine can obtain the construction data of the rest slave machines, so that each slave machine can adjust the construction process of the corresponding construction machine set and also can adjust the construction processes of the rest slave machines.
In this embodiment, the method for establishing the data sharing local area network of the construction unit includes: a data sharing local area network of the construction unit is established through the Lora networking module, so that data sharing can be realized between the host and each slave and between the slaves.
Further, the method for setting the data sharing equipment installed on one of the construction units as a master and the data sharing equipment installed on the other construction units as slaves includes the following steps: setting the host address as HostID; the slave addresses are set to { ID1, ID2, ID3, ID4, ID5, ID6 … … }, respectively.
In this embodiment, the construction machine set includes: PAD equipment of a first heater, a second heater, a third heater, a milling machine, a remixer, a paver and field management personnel; setting data sharing equipment on the paver as a host; the data sharing equipment set on the PAD equipment of the first heater, the second heater, the third heater, the milling machine, the remixer and the field manager is a slave machine.
Specifically, the host address of the paver is HostID.
Specifically, the address of the slave corresponding to the first heater is ID1, the address of the slave corresponding to the second heater is ID2, the address of the slave corresponding to the third heater is ID3, the address of the slave corresponding to the milling machine is ID4, the address of the slave corresponding to the remixer is ID5, and the address of the slave corresponding to the PAD device is ID 6; the slave address is a unique identification for each device.
The construction data includes: construction process data, machine daily maintenance information and repair information from the first heater, the second heater, the third heater, the milling machine and the remixer, and disease review data and construction adjustment information from the PAD equipment.
Specifically, when construction is started, the slave machine ID1-ID5 collects construction process data of a corresponding construction machine set in real time and mechanical daily overhaul information and repair report information input by a mechanical driver through an HMI (human machine interface) man-machine interaction module, and packs all collected data into a data packet; the ID6 slave computer collects the disease review data and construction adjustment information input by the manager in real time, and packs all the collected data into a data packet.
Then each slave waits for the master to send a data request command to perform data interaction, namely
The master accurately sends a data request command to the slave through the Lora networking module according to the address ID1 of the first slave, the slave responds to the master request and sends a corresponding data packet, and the master receives the data packet sent by the slave to complete one-time data interaction between the master and the ID1 slave.
After the host finishes data interaction with the ID1 slave, the host performs data interaction with the ID2 slave, and so on until the host finishes data interaction tasks with all the slaves, and after the host finishes data interaction with all the slaves in sequence, the host finishes a data collection process.
A slave can also send a data request command to the other slaves through the Lora networking module, that is, the other slaves respond to the slave request and send corresponding data packets.
Specifically, when the field manager inspects the construction state of the construction unit, the field manager can enter a data list of any slave machine through the PAD to check the construction process data, the daily mechanical maintenance information and the repair information, and can enter the parameter setting of any slave machine to adjust the construction process parameters and synchronize the construction adjustment information to the rest slave machines.
In addition, the construction process data of each heater includes: heating power P, heating temperature T and traveling speed V, and
t is K P/V-formula 1;
according to the formula 1, obtain
P ═ T × V/K — formula 2;
wherein K is an environmental coefficient;
when the heating power P1, the heating temperature T1 and the traveling speed V1 are set to correspond to the heating machines just started
K＝T1*V1/P1；
Substituting into equation 2 to obtain
P＝(T*V*P1)/(T1*P1)；
By adjusting the heating temperature T and the traveling speed V, the heating power P, that is, the heating temperature of each heater can be adjusted.
Specifically, a heating power of P1, a heating temperature of T1, and a traveling speed of V1 are the initial start-up of each heater, manual mode operation, which are custom parameters.
In the whole data sharing process, the adjustment of the heating power P can be realized only by adjusting the control temperature T and the unit speed V and combining respective defined parameters; for example, when a constructor at the end of the paver finds that the heating temperature is low, the constructor can enter a parameter setting interface of each heater through a human-computer interaction interface of each heater shared by the paver to modify the control temperature T and the unit speed V of each heater so as to adjust the heating power P, thereby adjusting the heating temperature of the corresponding heater and avoiding the problem that the response time is delayed to some extent due to the fact that the constructor runs to coordinate notification manually.
The method for the host to summarize and analyze the construction data to generate early warning information and send the summarized and analyzed construction data and the early warning information to the slave machines comprises the following steps: comparing each construction process data with a preset construction process parameter, and generating early warning information according to a comparison result; and the host sends the construction data and the early warning information after the summary analysis to each slave machine in a broadcasting mode, and all data sent by the host machine are received by any slave machine, so that the slave machines can operate independently, and the slave machines have the same operation function.
Specifically, after the data collection process is completed every time, the host machine collects and analyzes the construction process data of the paver and the data packets sent by the slave machines, compares the construction process data of each construction unit with preset construction process parameters, and generates early warning information; after the data summarization and analysis are completed, the host packs the summarized and analyzed unit construction process data, early warning information and construction adjustment information sent by the slave computers with the ID6 number into a summarized data packet, the summarized data packet is issued to a construction unit data sharing local area network established by a Lora networking module in a broadcasting mode, for example, but not limited to, each slave computer receives the data broadcasted by the host computer according to a HostID address, the construction process data, the early warning information and the construction adjustment information are displayed to corresponding equipment operators through HMI (human machine interface) man-machine interaction modules on the slave computers, and the equipment operators timely adjust the construction process according to the information and the construction processes of the rest slave computers. Thus, a complete data sharing process is completed.
Further, in the work progress, the site management personnel accessible PAD equipment is gathered the recheck to road disease, and specific process is: the PAD device provides dynamic and static basic data and disease data of a road before regeneration construction for managers in a mode of accessing a thermal regeneration construction management background or importing files, field managers detect and recheck on the field, record rechecked disease data and position information of the pile number of the disease from a slave computer with an ID6 number installed on the PAD device, pack rechecked disease data and position information of the pile number of the disease and a construction adjustment command input by the field managers into a complete construction adjustment information data packet, and transmit the construction adjustment information data packet to a host computer to finish data sharing when waiting for next interaction with the host computer. After the ID4 slave computer receives the shared data, disease data and the position information of the pile number of the disease are displayed through the HMI man-machine interaction module, so that a mechanical driver of the milling machine can accurately control the addition amount of new aggregate.
Furthermore, in the construction process, due to the large size of the system, in order to ensure the timely issuing of the construction process, under the condition that no person is temporarily arranged at a certain slave machine, the construction process data and the like of the slave machine can be issued through the setting of a human-computer interaction interface of the nearby slave machine; and when the slave machine is found to be abnormal, the construction state of the slave machine can be checked through a near slave machine human-computer interaction interface.
In this embodiment, the Lora-based hot-in-place recycling group data sharing method further includes: the host is suitable for storing the summarized and analyzed construction data and the early warning information into a data storage module; and each slave machine can access the stored construction data and the early warning information through the host machine.
Specifically, the host is suitable for issuing the summarized data packet to a construction unit data sharing local area network established by the Lora networking module, and simultaneously storing the summarized data packet into the data storage module by adopting a parallel processing mode.
In this embodiment 1, the Lora networking module is used to realize that the host sharing device can dynamically share the construction data and the state information with the slave sharing devices in real time, and each slave sharing device can also perform data sharing and construction linkage in real time, so as to avoid the problem that response time lags to some extent due to manual running for coordination notification, that is, when the device is required to adjust the construction process, the message is quickly transmitted, so that the process parameters of each sharing device are optimally matched, thereby improving the construction efficiency and the construction quality.
