An embodiment of the present invention provides a discharge control method, as shown in fig. 3, which is applied to a mixing station, where the mixing station includes a mixing host 1, and the discharge control method includes:
s1: acquiring the weight of the stirring main machine 1;
s2: when the weight of the stirring main machine 1 is greater than or equal to a first preset value, controlling a discharge door of the stirring main machine 1 to be opened; and when the weight of the stirring main machine 1 is smaller than the first preset value, controlling the discharge door of the stirring main machine 1 to close.
In S1, the weight of the mixer main body 1 is obtained by using the weight collecting unit 2, and the weight collecting unit 2 may be a weight sensor, an electronic scale, or other device capable of weighing. The weight acquisition part 2 is connected between the stirring main machine 1 and the discharge hopper 3, in one embodiment, the stirring main machine 1 is installed on a mounting frame, the weight acquisition part 2 is installed on the mounting frame, the stirring main machine 1 is further installed above the weight acquisition part 2, the discharge hopper 3 is located below a discharge opening of the stirring main machine 1, and a discharge door is installed at a discharge opening of the stirring main machine 1. The weight acquisition component 2 can acquire the weight of the stirring host machine 1 in real time, the control component can establish a change relation of the weight of the stirring host machine 1 along with time according to the weight acquired by the weight acquisition component 2, and the memory can store the change relation of the weight of the stirring host machine 1 along with time.
In S2, a feeding port is disposed on the main stirring machine 1, the weighing hopper feeds materials into the main stirring machine 1 through the feeding port, the first preset value may be preset, and the first preset value may be equal to 3% to 5% of the initial weight of the main stirring machine 1. The initial weight refers to the total weight of the stirring main machine 1 after the weighing hopper feeds the materials into the stirring main machine. Before the metering hopper feeds materials into the stirring main machine, firstly, weight judgment is carried out, the weight of the stirring main machine is judged to be less than or equal to a first preset value, meanwhile, whether a discharge door of the stirring main machine 1 is in a closed state is judged, and if the weight of the stirring main machine 1 is less than or equal to the first preset value and the discharge door of the stirring main machine 1 is in the closed state, the metering hopper is controlled to feed materials into the stirring main machine.
Therefore, by monitoring the weight of the stirring main machine 1, when the weight of the stirring main machine 1 is greater than or equal to a first preset value, the discharging door of the stirring main machine 1 is controlled to be opened; when the weight of the stirring main machine is smaller than or equal to a first preset value, the discharge door of the stirring main machine 1 is controlled to be closed, so that the situation that the stirring main machine 1 is blocked due to the fact that more materials still remain in the stirring main machine 1 when the materials are fed into the stirring main machine 1 can be avoided, and the waste of time caused by the fact that the discharge door is still opened to discharge the materials after the materials in the stirring main machine 1 are completely discharged can also be avoided.
In this embodiment, when the weight of the stirring main machine 1 is greater than or equal to a first preset value, the control of opening the discharge door of the stirring main machine 1 includes:
when the weight of the stirring main machine 1 is greater than or equal to the second preset value, controlling a discharge door of the stirring main machine 1 to be half opened;
when the weight of the stirring host machine 1 is greater than or equal to a first preset value and smaller than a second preset value, controlling the discharge door of the stirring host machine 1 to be fully opened, wherein the second preset value is greater than the first preset value.
That is, when the mixer main body 1 starts to discharge into the mixer truck 5, the discharge door of the mixer main body 1 is controlled to be half opened, and when the weight of the mixer main body 1 is equal to the second preset value, the discharge door of the mixer main body 1 is controlled to be fully opened. Half open here means that the discharge door of the mixer main body 1 can be opened by half, one third or two thirds. Of course, in certain embodiment, the discharge door of the mixer main body 1 may be controlled to be gradually opened as the discharging process proceeds until the discharge door is completely opened. The second preset value may be a times the initial weight, and a may be between 0.2 and 0.8. In some embodiments, the discharge door of the mixer main body 1 may be controlled to be opened first by one third, and then be kept for a while and then opened by one third until the discharge door of the mixer main body is completely opened.
Therefore, when discharging, the discharging door is firstly controlled to be half opened, so that the situation that more materials are stored in the stirring main machine 1, the inertia is larger, more materials are discharged at the moment when the discharging door is opened, and the materials overflow from the stirring truck 5 in the discharging process can be avoided, when the weight of the stirring main machine reaches the second preset value, the discharging door of the stirring main machine 1 is controlled to be fully opened, namely the discharging door is fully opened when the discharging is stable, the possibility of medical treatment is reduced, and the situation that the discharging speed is too slow due to the fact that the discharging door is half opened all the time can also be avoided.
In this embodiment, the discharge control method further includes: acquiring a material receiving image of the stirring vehicle 5; and correcting the second preset value according to the receiving image.
It should be noted that the mixing station further includes a discharge hopper 3 and an image acquisition component 4, the weight acquisition component 4 is located between the mixing host 1 and the discharge hopper 3, and the image acquisition component 4 is used for acquiring a material receiving image when the mixing truck 5 receives the material.
In an embodiment, the unloading speed of the stirring host 1 can be judged according to the material receiving image, and when the stirring host 1 unloads too fast or too slow, the second preset value can be increased or decreased.
In an embodiment, the correcting the second preset value according to the material receiving image includes: judging whether the stirring vehicle has material overflow or not according to the material receiving image; and when the stirring vehicle has material overflow, reducing the second preset value according to a preset correction value. Here, the discharge control device comprises a control part, the control part can compare the material receiving image with a preset flash image, and when the matching degree of the material receiving image and the preset flash image reaches a preset value, the situation that the flash occurs in the mixer truck is judged. The preset correction amount may be preset, and specifically, the preset correction amount may be 0.5 ton, 1 ton or 2 ton, where a specific value of the preset correction amount is not limited, and the preset correction amount may be related to the load of the main mixer 1. The advantage that sets up like this is through judging whether agitator truck 5 flash, when judging agitator truck 5 flash, in time to revise the second preset value reduces when fully opening the weight of stirring host computer 1, reduces the probability that flash takes place. The image of the material receiving of the front stirring vehicle 5 is monitored, the material receiving of the rear stirring vehicle 5 is guided, and the second preset value is corrected, so that the situation that the material receiving of the stirring vehicle 5 is not full or overflows due to inaccurate setting or production of the second preset value is avoided.
Therefore, by monitoring the material receiving image of the agitating lorry 5, the occurrence of abnormal events such as material overflow, too fast or too slow material receiving and the like caused by unreasonable setting of the second preset value can be avoided, and the second preset value is corrected in time.
In this embodiment, the correcting the second preset value according to the material receiving image includes:

and comparing the reference weight of the stirring main machine 1 with a second preset value, and updating the second preset value to the reference weight when the absolute value of the difference between the reference weight of the stirring main machine 1 and the second preset value is greater than a set difference.
And circulating the steps until an optimal second preset value is determined so as to ensure that the material receiving is fastest and no material overflow occurs. Here, the reference time for determining the agitator vehicle 5 according to the material receiving image may be a material receiving image of the agitator vehicle 5 when a material overflow occurs according to the material receiving image, and the reference time may be a certain time after the material overflow occurs. The second preset value may be preset, or may be automatically generated according to the acquired information of the mixer truck 5.
And when the absolute value of the difference between the reference weight and the second preset value is smaller than a set difference, keeping the second preset value unchanged. For example, the set difference may be 1 ton, the reference weight is 30 tons, the second preset value is 29.5 tons, and then the difference between the reference weight and the second preset value is 0.5 tons, keeping the second preset value unchanged. The following steps are repeated: the set difference may be 1 ton, the reference weight is 30 tons, and the second preset value is 27 tons, so that the difference between the reference weight and the second preset value is 9 tons, and the second preset value is reset to the reference weight, i.e., 30 tons.
And comparing the material receiving image with a preset flash image, when the matching degree of the material receiving image and the preset flash image reaches a preset value, judging that flash occurs in the agitating lorry, and at the moment, the corresponding material receiving moment is the flash moment. The preset time difference may be set in advance, for example, the preset time difference is 2 minutes, and it is assumed that the flash time is 12 months, 1 day, 11 months, 2020: 58, then, the reference time is 12/1/12 in 2020: 00. for another example, the preset time difference is 30 seconds, the flash time corresponding to the flash image is 10 points, 50 minutes and 30 seconds, and the reference time may be the time corresponding to the receiving image of the mixer truck 5 at 10 points, 51 minutes and 00 seconds.
Therefore, the material receiving image is monitored, the material overflowing time when the material overflowing occurs is monitored, after the material overflowing occurs, the material receiving image at a certain time after the material overflowing is finished is taken as a reference image of the best material receiving, the reference time corresponding to the image is determined, the reference weight corresponding to the time is determined as a second preset value, the second preset value is corrected, and the monitoring reliability is improved.
