Because the fourth electromagnetic valve 54 is closed, the water at the water outlet side of the water pump completely enters the first filter 41 through the water spraying control valve module 3, the second filter 42 and the third electromagnetic valve 53, the flushing pressure of the first filter 41 is increased, and the sewage discharge capacity is improved.
In addition, when water is sprayed, it is necessary to control the first solenoid valve 51, the second solenoid valve 52, and the third solenoid valve 53 to be closed and the fourth solenoid valve 54 to be opened.
In one embodiment, the sprinkler control valve module 3 includes: a first pipe, a second pipe, a third pipe, a fifth solenoid valve 31, and a sixth solenoid valve 32; the first end of the first pipeline is connected with the water outlet of the water pump module 2; the second end of the first pipeline is respectively connected with the first end of the second pipeline and the first end of the third pipeline; the second end of the second pipeline is connected with the sprinkling piece; the second end of the third pipeline is connected with the water inlet of the water tank 1; the fifth electromagnetic valve 31 is arranged on the second pipeline; the sixth electromagnetic valve 32 is arranged on the third pipeline; the fifth electromagnetic valve 31 and the sixth electromagnetic valve 32 are respectively connected to the controller 6, and the controller 6 is configured to control the opening or closing of the fifth electromagnetic valve 31 and the sixth electromagnetic valve 32.

Exemplary method
Fig. 4 is a schematic flow chart of a watering control method for a road roller according to an embodiment of the present application. The method of fig. 4 may be performed by the controller 6 in an exemplary sprinkler mechanism, and the embodiments of the present application are not limited thereto. As shown in fig. 4, the watering control method of the road roller comprises the following steps.
S410: and acquiring the road surface temperature and the running speed.
There are various ways of obtaining the road surface temperature and the travel speed of the road roller. Specifically, the mode of acquiring the running speed of the road roller can be that speed information is acquired through a sprinkler central control system; the mode of acquiring the road surface temperature may be to determine the road surface temperature through a set temperature acquisition device, or to acquire the road surface temperature of the position sent by other settings. When the roller compacted pavement is an asphalt pavement, the pavement temperature may be an asphalt temperature.
S420: based on the road surface temperature and the traveling speed, a control signal is generated.
S430: and controlling the watering state of the watering mechanism of the road roller according to the control signal.
The water spraying state of the water spraying mechanism may specifically include states such as whether water is sprayed or not, a water spraying speed, and the like.
In the watering control method for the road roller, a control signal is generated based on the road surface temperature and the running speed; and controlling the watering state of the watering mechanism of the road roller according to the control signal. So based on the speed automatic control watering mechanism's that traveles of road surface temperature and road roller watering state to make watering mechanism spill appropriate amount water, at this in-process, avoided judging the watering volume by the manual work, can spill more accurately, avoid splashing and spill the excess, avoid because excessive water can lead to mixture temperature to descend fast, cause the road surface compaction difficulty, influence the condition of road surface quality.
In one embodiment, "generating a control signal based on the road surface temperature and the travel speed" includes: and based on the road surface temperature and the running speed, generating a control signal according to the principle that the higher the road surface temperature is, the larger the sprinkling quantity in the preset time period is, and/or the higher the running speed is, the larger the sprinkling quantity in the preset time period is.
It should be noted that, based on objective conditions, in a preset time period, the higher the temperature of the road surface, the larger the required water spraying amount is, and the faster the running speed is, the larger the required water spraying amount is, so that the temperature of the mixed material is reduced to a proper range, and the quality of the compacted road surface is improved. Based on this, the control command should be generated in accordance with the principle that the higher the road surface temperature is, the larger the sprinkling amount per unit time is, and the faster the running speed is, the larger the sprinkling amount is in the preset time period. The preset time period may be the working time of the road roller rolling the road surface.
Specifically, the control signal is generated based on the road surface temperature and the running speed, and comprises:
s421, determining the watering duration and the watering interval duration based on the road surface temperature and the driving speed;
wherein the sprinkling time is the time for each sprinkling; the time length of the watering interval is the time length from the kth watering ending time to the kth +1 watering starting time, and k is a positive integer.
Specifically, when the watering time is determined, consideration should be given to the fact that the surface of the whole roller rotating circle can be watered in one-time watering time. According to the arrangement, water is uniformly distributed on the surface of the roller, and the water on the roller can be uniformly sprayed on the road surface in the road pressing process.
And S422, generating a control signal for controlling the watering state of the watering mechanism of the road roller based on the watering time length and the watering interval time length.
So set up, can be based on length of time and the length of time control holistic watering volume of watering interval of watering every time. Need not frequent opening of water pump and stopping, also need not the operating frequency of regulation water pump, alright in order to adjust the watering volume.
Further, based on the road surface temperature and the running speed, the watering duration and the watering interval duration are determined, and the method comprises the following steps:
determining the watering time length and the watering interval time length through a pre-constructed mapping relation based on the road surface temperature and the driving speed;
the mapping relation is used for representing the watering time length and the watering interval time length corresponding to different road surface temperatures and different driving speeds.
Specifically, the faster the driving speed, the shorter the watering duration, the shorter the watering interval duration, and the watering interval duration is also related to the road surface temperature, and the higher the road surface temperature, the shorter the watering interval duration. For example, the watering interval duration is a product of a reference interval duration which is the same as the watering interval duration and a temperature coefficient a which is smaller as the road surface temperature is higher. Through above-mentioned mapping relation, it is long more according with the operating mode demand when watering, and the watering interval is long, and the watering volume can not only better solution roll the time glue the wheel, for rolling the tire cooling, can also avoid extravagant.
The mapping relationship may be, but is not limited to being, represented by a data table. A specific embodiment is described as follows:
in one embodiment, the travel speed of the roller is controlled by a twelve-gear switch, which corresponds to a travel speed of 1 to 12 km/h. The water can be sprayed at the construction speed of 1-8 gears (the speed of 9-12 gears is too fast, and the water is not generally used for road rolling, so the water spraying condition of 9-12 gears is not considered). Referring to the table 1, the watering duration is related to the running speed, so that the watering duration can cover the surface of the roller rotating for one circle; further, the watering interval duration includes a reference interval duration and a temperature coefficient a, in table 1, the reference interval duration is the same as the watering interval duration, and in other embodiments, the reference interval duration may also be a preset multiple of the watering interval duration. Further, referring to table 2, at a road surface temperature of 100 ℃, the water spraying time period is the same as the water spraying interval time period, i.e., the temperature coefficient a is 1. When the road surface detection temperature is 100 to 120 ℃, the watering interval time length is 0.9 times of the reference interval time length, namely the temperature coefficient a is 0.9, and when the road surface temperature is 120 to 150 ℃, the interval time length is 0.8 times of the reference interval time length, namely the temperature coefficient a is 0.8. The higher the pavement temperature, the shorter the sprinkling interval duration.
