[0020] Figure 1 The structure diagram of the asphalt pavement intelligent construction management and control system based on Internet of Things described in the embodiment of the present application. Detailed Implementation

[0021] The present invention will now be described in further detail with reference to the accompanying drawings, so that those skilled in the art can implement it based on the description.

[0022] like Figure 1 As shown, this embodiment of the invention provides an intelligent construction management and control system for asphalt pavement based on the Internet of Things, including: a speed measuring device installed on a road roller used for compacting asphalt pavement, for monitoring the actual travel speed of the road roller; a temperature measuring device installed at the bottom of the road roller, for monitoring the actual temperature of the asphalt pavement; an ambient temperature monitoring device, for monitoring the actual temperature of the construction environment; a vehicle-mounted terminal installed on the road roller, communicatively connected to the speed measuring device, for receiving the actual travel speed of the road roller; and a monitoring terminal communicatively connected to the temperature measuring device, the ambient temperature monitoring device, and the vehicle-mounted terminal, for receiving the asphalt pavement... The monitoring terminal is configured with a pre-set construction temperature range. It is used to determine the estimated temperature drop rate of the asphalt pavement based on the actual temperature of the asphalt pavement and the actual temperature of the construction environment; to determine the estimated temperature drop time of the asphalt pavement based on the temperature difference between the actual temperature of the asphalt pavement and the lower limit of the construction temperature range, and the estimated temperature drop rate; and to determine the reference travel speed of the road roller based on the compaction distance and the estimated temperature drop time. The monitoring terminal is used to send the reference travel speed of the road roller to the vehicle-mounted terminal.

[0023] Here, the construction temperature range can be the construction temperature of the asphalt pavement determined according to the construction design. The construction temperature range may also vary depending on the stage of the compaction operation.

[0024] The actual temperature of the construction environment is the most critical factor affecting the temperature of the asphalt pavement. Therefore, the monitoring terminal can determine the temperature drop law of the asphalt pavement, i.e., estimate the temperature drop speed, according to the actual temperature of the asphalt pavement and the actual temperature of the construction environment. Then, the monitoring terminal can further determine the estimated temperature drop time of the asphalt pavement according to the estimated temperature drop speed and the temperature difference between the actual temperature of the asphalt pavement and the lower limit value in the construction temperature interval. Next, according to the distance of the current stage of the roller compactor and the estimated temperature drop time, the monitoring terminal can determine the reference travel speed of the roller compactor. The monitoring terminal sends the working parameter to the vehicle-mounted terminal, and the vehicle-mounted terminal also receives the actual travel speed of the roller compactor. The driver maintains the actual travel speed of the roller compactor above the reference travel speed according to the provided reference travel speed. In this case, the current stage of the roller compaction work on the asphalt pavement can be completed before the actual temperature of the asphalt pavement drops outside the construction temperature interval.

[0025] The asphalt pavement is segmented and rolled, so the current stage of the roller compaction work on the asphalt pavement can be completed before the actual temperature of the asphalt pavement drops outside the construction temperature interval, thereby ensuring the construction quality.

[0026] In a preferred embodiment, the monitoring terminal compares the actual temperature of the asphalt pavement with the construction temperature interval, generates an alarm prompt when the actual temperature of the asphalt pavement is greater than the upper limit value of the construction temperature interval or less than the lower limit value of the construction temperature interval, and sends the alarm prompt to the vehicle-mounted terminal to remind the driver to stop the roller compactor from rolling the asphalt pavement.

[0027] In actual application, the actual temperature of the asphalt pavement may not meet the construction temperature interval, for example, the actual temperature of the asphalt pavement is too high and has not reached the construction condition, or the actual temperature of the asphalt pavement drops below the lower limit value of the construction temperature interval due to weather changes at a speed exceeding the estimated temperature drop speed. For the above-mentioned situations, the monitoring terminal can identify and generate an alarm prompt in time, and the driver stops the roller compaction work on the asphalt pavement according to the alarm prompt sent by the vehicle-mounted terminal.

[0028] In a preferred embodiment, the monitoring terminal establishes a working parameter database, and the working parameter database pre-stores the temperature drop speed of the asphalt pavement under multiple temperature conditions of the construction environment and multiple temperature conditions of the asphalt pavement.

[0029] The temperature drop rule of the asphalt pavement under multiple temperature conditions of the construction environment and multiple temperature conditions of the asphalt pavement can be constructed according to the collected historical data and stored in the working parameter database.

[0030] In a preferred embodiment, the monitoring terminal is configured to search for the temperature drop speed of the asphalt pavement under the condition that the actual temperature of the construction environment and the actual temperature of the asphalt pavement are matched in the working parameter database, as the estimated temperature drop speed of the asphalt pavement, according to the actual temperature of the construction environment and the actual temperature of the asphalt pavement.

[0031] Specifically, the record consistent with the actual temperature of the construction environment and the actual temperature of the asphalt pavement is found in the working parameter database, and the corresponding temperature drop speed is taken as the estimated temperature drop speed of the asphalt pavement. When no completely consistent record is searched, the record with the smallest gap can be selected, for example, the actual temperature of the construction environment is 10℃, the actual temperature of the asphalt pavement is 102℃, and the corresponding temperature condition of the asphalt pavement under the temperature condition of 10℃ of the construction environment in the database is not 102℃, and the smallest gap is 100℃, so the temperature drop speed of the asphalt pavement corresponding to the temperature condition of 10℃ of the construction environment and the temperature condition of 100℃ of the asphalt pavement can be selected as the estimated temperature drop speed of the asphalt pavement.

[0032] In a preferred embodiment, the distance of the rolling operation of the road roller in the Internet of Things-based intelligent asphalt pavement construction management and control system is obtained by multiplying the length of the asphalt pavement and the number of rolling times of the road roller on the asphalt pavement in the current construction stage.

[0033] The length of the asphalt pavement refers to the length of the section of the asphalt pavement in the current rolling operation. The road roller may need to roll the asphalt pavement multiple times in a construction stage, therefore, the distance of the rolling operation of the road roller should be calculated by multiplying the length of the asphalt pavement and the number of rolling times.

[0034] In a preferred embodiment, the monitoring terminal of the Internet of Things-based intelligent asphalt pavement construction management and control system has a construction management database; the monitoring terminal is configured to store the actual temperature of the asphalt pavement when the rolling operation of the road roller on the asphalt pavement starts and the actual temperature of the asphalt pavement when the road roller completes the rolling operation of the current stage on the asphalt pavement in the construction management database, and record the name of the current stage in the construction management database.

[0035] The rolling operation can include initial rolling, re-rolling, final rolling and the like. The embodiment stores and records the initial temperature and the final temperature of the asphalt pavement in different stages of the rolling operation, facilitating subsequent query management.

[0036] In a preferred embodiment, the vehicle-mounted terminal is further configured to send the actual travel speed of the road roller to the monitoring terminal, and the monitoring terminal is configured to store the actual travel speed of the road roller as the rolling speed of the road roller in the construction management database.

[0037] The embodiment stores and records the rolling speed of the road roller in the rolling operation, facilitating subsequent query management.
