Mixing host discharge door opening control system, method, electronic equipment, storage medium and mixing station

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to the Chinese patent application filed with the China Patent Office on September 15, 2023, with application number 202311200792.2 and invention name “Control system and method for the opening degree of the discharge door of the mixing main machine”, the entire contents of which are incorporated by reference into this application. Technical Field

[0003] The present application relates to the field of automatic control technology, and in particular to a control system, method, electronic equipment, storage medium and mixing station for the opening degree of a discharging door of a mixing main machine. Background Art

[0004] The existing unloading door control method of each mixing station main plant is to divide the unloading door into three fixed positions: fully closed, half open, and fully open through a proximity switch. After the proximity switch is fixed, the half-open opening is fixed, and the half-open and fully open times are maintained through a preset fixed concrete unloading countdown, thereby completing the main machine's concrete unloading.

[0005] However, concrete with different properties exhibits varying fluidity, resulting in varying speeds of flow into the truck mixer hopper. Therefore, unloading concrete at a fixed opening reduces efficiency and can easily cause spillage and scattering. Furthermore, the existing manual control of the three-position opening and closing of the discharge gate consumes significant operator time and energy, resulting in low efficiency. There is a fixed delay of approximately 1.5 seconds between the operator noticing a spill and pressing the switch and the on-site flow being stopped and overflow control implemented. Furthermore, manual response time from discovery to control typically takes approximately 3 seconds. This extended control time also easily leads to spillage and scattering. Consequently, existing control methods struggle to prevent spillage and scattering, and are inefficient.

[0039] To make the objectives, technical solutions, and advantages of this application more clear, the technical solutions of this application will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments of this application, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of this application.

[0040] The following describes the mixing host discharge door opening control system and method of the present application in conjunction with Figures 1 to 3.

[0041] FIG1 is a structural diagram of a control system for the opening degree of a discharge door of a mixing main machine provided in the present application. As shown in FIG1 , a control system for the opening degree of a discharge door of a mixing main machine includes: a controller and a plurality of discharge gears.

[0042] The controller is used to adjust the unloading gear according to the unloading amount of concrete in the receiving hopper; the unloading gear is used to adjust the opening of the unloading door.

[0043] The unloading gear includes an induction gear and a time gear 1.

[0044] The sensing gear position includes a fully closed gear position 2 and a preset proportional gear position 3; the preset proportional gear position 3 is set between the middle position and the fully closed gear position 2, and the middle position is the position of a conventional half-open gear position.

[0045] The time gear 1 is set between the preset ratio gear 3 and the full-open gear 4, and the opening ratio of the time gear 1 is determined according to the strength and / or slump of the concrete to be discharged.

[0046] It should be noted that the position of the conventional half-open gear is the position of the half-open gear in the prior art.

[0047] Specifically, the multiple unloading gears refer to time gear 1, full-close gear 2, preset ratio gear 3 and full-open gear 4.

[0048] In a specific embodiment, the unloaded concrete amount may be the material level height in the hopper.

[0049] In the present application, the conventional fixed half-open gear is cancelled and a preset proportional gear is set, wherein the preset proportional gear is set between the middle position and the fully closed gear, that is, the discharge hopper opening of the preset proportional gear is smaller than the fixed half-open gear of the prior art, which makes it easier to control the speed of unloading concrete. When there is a risk of overflow or scattering, the present application can ensure that the concrete is unloaded at a smaller flow rate to avoid overflow or scattering. In addition, the present application also sets the time gear according to the strength and slump of the material to be unloaded, so that materials with different strengths and / or slumps to be unloaded have an optimal unloading opening, fundamentally reducing the occurrence of overflow or scattering. In the present application, the unloading gear is controlled by a controller, thereby controlling the unloading door opening, realizing automatic control of the unloading door opening, improving control efficiency, and avoiding overflow or scattering caused by untimely control.

[0050] In a specific embodiment, the preset ratio of the preset ratio gear position 3 can be selected as one third, that is, it is set close to the fully closed gear position and located at one third of the position between the fully closed gear position and the fully open gear position.

[0051] In a specific embodiment, the sensing gear position is specifically indicated by a sensing gear position switch, and the type of the sensing gear position switch is a proximity sensor.

[0052] In a specific embodiment, timer level 1 does not involve a sensor; its opening ratio is controlled by controlling its execution time (a first preset duration). Specifically, the initial operation time of timer level 1 is determined based on the strength of the concrete to be discharged. Based on this initial operation time, the final execution time (i.e., the first preset duration) is determined by matching the slump correction factor. This ensures that each concrete of varying strength has an optimal initial opening.

[0053] In a specific embodiment, the correction coefficient κ of the slump is in the range of (0, 2], and the execution time = initial action time * κ.

[0054] In a specific embodiment, time gear 1 is also preset with an opening maintenance countdown, and the countdown duration for maintaining the opening ratio of the time gear is a second preset duration. It is used to start the opening maintenance countdown of the time gear when the unloading door is opened with the opening of time gear 1, to ensure that the material to be unloaded in the mixing host can be successfully unloaded at the current opening, and to close time gear 1 in time to complete the entire concrete unloading process.

[0055] Furthermore, the second preset duration is preset based on the strength of the concrete to be discharged, and can be set based on the estimated normal flow rate. Specifically, since the discharge gear may need to be changed during the concrete discharge process, that is, the discharge door opening may need to be adjusted, the second preset duration can be set slightly longer than the time required for the entire concrete discharge process to be carried out entirely at the opening ratio of time gear 1, to ensure smooth completion of the concrete discharge process.

[0056] Specifically, for a 4-cubic-meter mixing main unit, the countdown (i.e., the second preset duration) of the opening of the C30 concrete time gear 1 is maintained at about 35 seconds.

[0057] In a specific embodiment, there is at least one preset proportional gear 3. When there are multiple preset proportional gears 3, at least one preset proportional gear 3 is set between the middle position and the fully closed gear 2. That is, the present application can set multiple preset proportional gears to meet the concrete unloading needs of different scenes under different intensities.

[0058] In a specific embodiment, the sensing gear further includes a fully open gear 4, as shown in Figure 1. The significance of setting the fully open gear in the present application is that when the amount of unloaded concrete in the hopper is less than or equal to the preset unloading concrete remaining threshold within the third preset time period, the remaining countdown process of the time gear is skipped and the opening of the unloading door is adjusted to the fully open gear, so that the remaining material can be unloaded quickly and the unloading efficiency of the concrete can be improved. It should be noted that the judgment condition of the third preset time length is set in this application in order to improve the accuracy of recognition. Because if the amount of unloaded concrete in the hopper is detected to be less than or equal to the preset unloading concrete remaining threshold only at a certain moment, it may be a detection error, or it may be caused by uneven distribution of materials in the hopper. If the opening of the unloading door is adjusted to the fully open position at this time, it may cause overflow or scattering of materials. Therefore, this application adjusts the opening of the unloading door to the fully open position when the amount of unloaded concrete in the hopper is less than or equal to the preset unloading concrete remaining threshold within the third preset time length (or uses image recognition to detect continuous frames). This can avoid overflow or scattering of materials and improve the efficiency of unloading concrete.

[0059] Furthermore, in the present application, the countdown timer for the fully open gear 4 can also be set. The countdown timer for the fully open gear is generally 2-3 seconds, which is used to stop the concrete unloading process in real time after the concrete unloading is completed.

[0060] In a specific embodiment, the mixing host discharge door opening control system may also include a video acquisition module and a display screen, both of which are connected to the controller. The video acquisition module is used to acquire the process image of concrete unloading, and the display screen is used to display the process image of concrete unloading in the form of video, so that the concrete unloading status can be grasped in real time.

[0061] In a specific embodiment, the control system for the opening degree of the discharge door of the mixing main machine may further include a material level detection module for detecting the amount of discharged concrete in the receiving hopper.

[0062] In a specific embodiment, there is at least one key detection area in the hopper for supplying a material level detection module to detect the amount of unloaded concrete.

[0063] Among them, when there are two key detection areas in the hopper and the feeding position detection module detects the unloading amount of concrete, different overflow warning thresholds are corresponding to the two key areas. When the unloading amount of concrete in the two key areas is greater than or equal to the corresponding overflow warning threshold, it is determined that there is a risk of overflow or scattering.

[0064] In addition, the two key areas also correspond to different overflow alarm thresholds. When the unloading amount of at least one of the two key areas is greater than or equal to the corresponding overflow alarm threshold, it is determined that overflow or spillage occurs.

[0065] The following describes the method for controlling the opening of the discharge door of the mixing main unit provided in this application. The method for controlling the opening of the discharge door of the mixing main unit described below and the control system for the opening of the discharge door of the mixing main unit described above can be referred to in correspondence with each other.

[0066] As shown in FIG2 , the present application further provides a method for controlling the opening of a mixing host discharge door. The method uses a mixing host discharge door opening control system, the system comprising: a controller and a plurality of discharge gears; the discharge gears comprising a sensing gear and a time gear; the sensing gears comprising a fully closed gear and a preset ratio gear; the method comprising:

[0067] Step 201: obtaining the opening ratio of the time gear; the opening ratio of the time gear is determined according to the strength and / or slump of the concrete to be discharged.

[0068] Among them, the strength of the concrete to be unloaded is determined by the upper computer based on the order information of the concrete to be unloaded, and then the upper computer sends the corresponding information to the control system of this application; the slump of the concrete to be unloaded is detected by the slump detection module, and then the slump detection module sends the corresponding detection data to the control system of this application; finally, the control system of this application determines the opening ratio of the time gear through calculation based on the received strength and / or slump of the concrete to be unloaded.

[0069] Step 202: Open the discharge door at the opening ratio of the time gear.

[0070] In a specific embodiment, the time gear can be initially opened in a one-time action. When it is necessary to adjust the opening ratio from the preset proportion gear to the opening ratio of the time gear, the opening ratio of the time gear is achieved by the controller by controlling the execution time of the time gear, that is, the time gear can be adjusted from the preset proportion gear to the opening ratio of the time gear after a first preset time length.

[0071] In a specific embodiment, the first preset duration can be determined as follows:

[0072] An initial action time is determined based on the strength of the material to be unloaded, and then based on the initial action time, the final execution time, i.e., the first preset duration, is determined by matching the correction coefficient of the slump. This ensures that belt unloading of different strengths has an optimal initial opening.

[0073] In a specific embodiment, the correction coefficient κ of the slump is in the range of (0, 2], and the execution time = initial action time * κ.

[0074] Step 203: Obtain the amount of unloaded concrete in the receiving hopper.

[0075] The amount of concrete discharged from the receiving hopper can be the material level height, which is determined by the material level detection module, and the opening ratio of the time gear is pre-set according to the material to be discharged.

[0076] Step 204: When the amount of concrete discharged from the receiving hopper is greater than or equal to the preset overflow warning threshold, the opening of the discharge door is adjusted to the preset proportional gear position.

[0077] In a specific embodiment, when the amount of concrete discharged into the receiving hopper is greater than or equal to the preset overflow warning threshold, it indicates that there is a risk of overflow or scattering. Therefore, after identifying the risk, the opening ratio of the initial time gear is reduced to the preset ratio gear, and the opening of the discharge door is adjusted to reduce the unloading speed of the main machine, so that the incoming material speed is lower than the feeding speed of the mixer truck, ensuring that the amount of concrete discharged into the receiving hopper is maintained within a range less than the preset overflow warning threshold to avoid overflow or scattering.

[0078] In a specific embodiment, the overflow warning threshold is generally about 70% of the hopper height.

[0079] Step 205: When the amount of concrete discharged from the receiving hopper is greater than or equal to the preset overflow alarm threshold, the opening of the discharge door is adjusted to the fully closed position.

[0080] In a specific embodiment, when the amount of concrete discharged into the receiving hopper is greater than or equal to the preset overflow alarm threshold, it indicates that overflow or spillage is about to occur or has occurred, so it is necessary to adjust the opening ratio of the initial time gear to the fully closed gear. By adjusting the opening of the discharge door, the main machine unloading is suspended, and the material temporarily stored in the hopper is discharged to the mixer truck as soon as possible to ensure that the amount of concrete discharged into the hopper is maintained within a range less than the preset overflow warning threshold to avoid overflow or spillage.

[0081] In a specific embodiment, the overflow alarm threshold is generally about 90% of the hopper height.

[0082] In a specific embodiment, when the amount of concrete discharged into the receiving hopper is less than a preset overflow warning threshold, the opening ratio of the time gear is maintained until the countdown of the opening ratio of the time gear ends, and the countdown duration of the opening ratio of the time gear is a second preset duration.

[0083] That is, the time gear in this application is also preset with an opening maintenance countdown, and the countdown duration for maintaining the opening ratio of the time gear is maintained as a second preset duration. It is used to start the opening maintenance countdown of the time gear when the unloading door is opened with the opening of the time gear, and is used to ensure that when there is no overflow or scattering of material during the entire concrete unloading process, the time gear is closed in time to complete the entire concrete unloading process.

[0084] Furthermore, the second preset time duration is preset and can be set to a specific time according to the estimated time corresponding to the normal flow rate. Specifically, since the unloading gear may be changed during the concrete unloading process, that is, the opening of the unloading door may be adjusted, the second preset time duration can be set to be slightly longer than the time required for the entire concrete unloading process to be completed at the opening of time gear 1 to ensure smooth completion of the concrete unloading process.

[0085] Specifically, the opening of the time gear is maintained for a countdown (ie, the second preset duration) of about 35 seconds.

[0086] In a specific embodiment, when the amount of unloaded concrete in the receiving hopper is less than or equal to the preset unloaded concrete remaining threshold value within a third preset time period, the countdown is skipped and the opening of the discharge door is adjusted to the fully open position. Specifically, the judgment condition of the third preset time period is set in this application to improve the accuracy of recognition. Because if the amount of unloaded concrete in the hopper is detected to be less than or equal to the preset unloaded concrete remaining threshold value only at a certain moment, it may be due to a detection error or uneven distribution of the material in the hopper. If the opening of the discharge door is adjusted to the fully open position at this time, it may cause overflow or scattering of material. Therefore, this application adjusts the opening of the discharge door to the fully open position when the amount of unloaded concrete in the hopper is less than or equal to the preset unloaded concrete remaining threshold value within the third preset time period. In addition, adjusting to the fully open position can discharge the remaining material as quickly as possible, that is, this solution in this application can avoid overflow or scattering of material and improve the efficiency of unloading concrete.

[0087] In a specific embodiment, the unloading concrete remaining threshold is generally about 10% of the hopper height. In addition, the third preset time length can be 2-3 seconds.

[0088] In a specific embodiment, the fully open gear also has an opening maintenance countdown function, which is used to start the full-open opening maintenance countdown when the unloading door is opened in the fully open gear. Because when the unloading door is opened in the fully open gear, it is generally suitable for when the unloading of concrete is nearing the end. Through the opening maintenance countdown of the fully open gear, the fully open gear can be closed in time to complete the entire concrete unloading process.

[0089] It should be noted that the countdown for maintaining the opening of the full gear is generally 2-3 seconds.

[0090] In a specific embodiment, after adjusting the opening of the discharge door to the preset proportional gear, the method further includes:

[0091] When the amount of concrete discharged from the hopper is less than the preset overflow warning threshold, the discharge door opening is adjusted to the opening ratio of the time gear. That is, when the amount of concrete discharged from the hopper reaches a normal state (less than the preset overflow warning threshold), the concrete is discharged at the opening ratio of the time gear that best matches the current material. This can ensure the discharge speed while reducing the occurrence of overflow or material spillage to a certain extent.

[0092] In a specific embodiment, it takes a first preset time period to adjust the opening of the discharge door from the preset ratio gear to the opening ratio of the time gear.

[0093] In a specific embodiment, after adjusting the opening of the discharge door to the fully closed position, the method further includes:

[0094] When the amount of concrete discharged from the hopper is less than the preset overflow warning threshold, the discharge door opening is adjusted to the opening ratio of the time gear. That is, when the amount of concrete discharged from the hopper reaches a normal state (less than the preset overflow warning threshold), the concrete is discharged at the opening ratio of the time gear that best matches the current material. This can ensure the discharge speed while reducing the occurrence of overflow or material spillage to a certain extent.

[0095] In a specific embodiment, the above control process of the mixing host discharge door opening control method can also be used to collect and display images through a video acquisition module and a display screen, so as to display the concrete unloading process in the form of video, so that the concrete unloading status can be grasped in real time.

[0096] In a specific embodiment, there is at least one key detection area in the hopper for supplying a material level detection module to detect the amount of unloaded concrete.

[0097] Among them, when there are two key detection areas in the hopper and the feeding position detection module detects the unloading amount of concrete, different overflow warning thresholds are corresponding to the two key areas. When the unloading amount of concrete in the two key areas is greater than or equal to the corresponding overflow warning threshold, it is determined that there is a risk of overflow or scattering.

[0098] In addition, the two key areas also correspond to different overflow alarm thresholds. When the unloading amount of at least one of the two key areas is greater than or equal to the corresponding overflow alarm threshold, it is determined that overflow or spillage occurs.
