Description

Technical Field

[0001] The present invention relates to the field of dust control at urban construction sites, and in particular to an intelligent spray automatic networking system and method for dust prevention at urban construction sites. Background Art

[0002] At present, all major cities are in the peak period of urban construction, and most urban construction sites are located in urban areas or surrounding areas. Environmental protection laws and regulations have put forward higher requirements for dust control on construction sites. However, during the construction process, foundation excavation, building materials transportation, and equipment disturbances cause a lot of dust pollution, which not only causes serious environmental pollution on the construction site, but also has a serious impact on the surrounding environment. How to effectively control the dust pollution level and polluted areas throughout the construction process has become an urgent concern and problem to be solved at urban construction sites.

[0003] At present, most of the dust prevention methods for fences in urban construction sites are sprinkling water or spraying. On the one hand, their layout positions are fixed, and the position of the spray device cannot be changed according to the changes in the pollution level in the construction site area; on the other hand, the spray flow rate is relatively fixed, and the spray flow rate cannot be increased due to increased pollution level, resulting in insufficient dust prevention ability, and the spray flow rate cannot be reduced due to reduced pollution level, resulting in waste; in addition, traditional dust prevention methods cannot predict the pollution area and pollution level in advance, resulting in delayed dust prevention work. Summary of the invention

[0004] The purpose of the present invention is to provide an intelligent automatic networking system and method for dust prevention at urban construction sites, which can automatically adjust the water flow rate of the spray device, the number and position of the spray device according to the changes in dust in the circulating track area, realize automatic networking of the spray device for dust removal, greatly improve work efficiency and avoid unnecessary waste of resources.

[0005] The present invention adopts the following technical scheme to achieve the above-mentioned purpose: an urban construction site dust prevention intelligent spray automatic networking system, comprising a circulating track 1, a spray device, a dust detection device and a control module, wherein the circulating track 1 comprises at least two main tracks 2, the multiple spray devices can run along one of the main tracks 2, the multiple dust detection devices can run along the other main track 2, and the spray device and the dust detection device are wirelessly connected to the control module respectively;

[0006] The circulating track is used for the bidirectional operation of the spray device and the dust detection device;

[0007] The dust detection device is used to detect the concentration and range data information of dust pollution in the circulation track area in real time, and send the detected data information to the control module;

[0008] The control module is used to calculate and analyze the spray flow rate and the number of spray devices required for the pollution distribution area, and control the automatic networking of the spray devices for dust removal and the real-time scheduling of the spray devices during the dust removal process;

[0009] The spray device is used to receive instructions from the control module and automatically form a network and move to a designated area for dust removal.

[0010] Furthermore, in order to improve the stability of the spray device and the dust detection device running on the main track, the circulating track 1 also includes at least two auxiliary tracks 4, and the auxiliary track 4 includes a groove 3, and one end of the auxiliary rod of the spray device and the dust detection device is stuck in the groove 3.

[0011] Furthermore, in order to more accurately determine the current position of the spray device, the main track 2 is provided with raised unit scales.

[0012] Furthermore, in order to improve the dust removal efficiency of the system, the spray device and the dust detection device can run bidirectionally on the main track 2.

[0013] Furthermore, in order to improve the stability of the circulating track, the automatic networking system of intelligent spray for dust prevention at urban construction sites also includes a fixed base 5, which is used to fix the circulating track 1. The fixed base 5 includes at least two bolt holes 6 and one track connector hole 7. The circulating track 1 is fixed to the fence around the urban construction site through the fixed base 5.

[0014] The automatic networking method of intelligent spraying for dust prevention in urban construction sites is applied to the automatic networking system of intelligent spraying for dust prevention in urban construction sites described above, and includes the following method steps:

[0015] Step (1), obtaining dust pollution data of the circulation track area in real time;

[0016] Step (2), analyzing and drawing a dust pollution distribution map of the circulation track area;

[0017] Step (3), obtaining the spray flow rate and number of spray devices required for the contaminated area;

[0018] Step (4), controlling the spray device to automatically network and remove dust;

[0019] Step (5), controlling the real-time scheduling of the spray device during the automatic network dust removal process.

[0020] Furthermore, in step (1), real-time acquisition of dust pollution data of the circulating track area includes: the dust detection device moves on the track, stops moving when it moves to a set detection point, detects dust pollution concentration at the set detection point, and sends the scale on the current track and dust pollution concentration data information to the control module.

[0021] Furthermore, in step (3), the calculation and analysis of the spray flow rate and the number of spray devices required for the polluted area include: according to the dust range L of the polluted area and the control range L1 of a single spray device, the number of spray devices required in this area can be obtained as U1>L / L1; according to the dust concentration and range of the polluted area, the required water volume V is obtained, and combined with the maximum water flow rate S of a single spray device, the number of spray devices required in the polluted area can be obtained as U2>V / S, and the sizes of U1 and U2 are compared, and the maximum value is taken as the number of spray devices required for the polluted area.

[0022] Furthermore, in step (5), controlling the real-time scheduling of the spray device in the automatic network dust removal process includes: during the dust removal process of the spray device, if the dust pollution concentration in a certain area continues to increase, the water flow rate of the spray device in the area is increased first; if the water flow rate of the spray device reaches the maximum, the number of spray devices in the area is increased; if the dust pollution concentration in a certain area decreases, the water flow rate of the spray device is reduced first; if other polluted areas need to increase the spray device, the number of spray devices in the area is reduced.

[0023] The dust detection device and the spray device of the present invention can run bidirectionally on the main track.

The control module calculates and analyzes the data, calculates and analyzes the spray flow rate and the number of spray devices required in the polluted area, and controls the spray device to be networked and moved to the polluted area for dust removal in combination with the current position of the spray device. In the process of dust removal, if the dust pollution concentration in a certain area continues to increase, the water flow rate of the spray device in the area is increased first. If the water flow rate of the spray device reaches the maximum, the number of spray devices in the area is increased. If the dust pollution concentration in a certain area decreases, the water flow rate of the spray device is reduced first. If other polluted areas need to increase the spray device, the number of spray devices in the area is reduced. The water flow rate of the spray device, the number of spray devices and the position of the spray device are automatically adjusted according to the dust concentration and range changes in the polluted area, which greatly improves the dust removal efficiency and effectively avoids waste of resources.
