[0051] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0052] The present invention is described in detail below in conjunction with the accompanying drawings of the specification. The specific operating method in the method embodiment can also be applied to the device embodiment or the system embodiment. In the description of the present invention, unless otherwise specified, "at least one" includes one or more. "Multiple" refers to two or more. For example, at least one of A, B and C includes: A exists alone, B exists alone, A and B exist at the same time, A and C exist at the same time, B and C exist at the same time, and A, B and C exist at the same time. In the present invention, " / " means or, for example, A / B can mean A or B; "and / or" in this article is only a kind of association relationship that describes the associated objects, indicating that there can be three relationships. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone.

[0053] Figure 1 , Figure 2 and Figure 3 It is a schematic diagram of the layout relationship of the mixing station provided by the present invention, which mainly shows the connection relationship between the pump body 10 and the first tank body 20 and the second tank body 30.

[0054] In a possible implementation, the pump body 10 may also be referred to as a material pump or a pump.

[0055] like Figure 1 As shown, the first tank body 20 and the second tank body 30 are respectively connected to the same pump body 10.

[0056] like Figure 2 As shown, the first tank body 20 and the second tank body 30 are respectively connected to the corresponding pump body 10.

[0057] like Figure 3 As shown, there is a one-to-one correspondence between the material tank and the pump body 10 , that is, one first tank body 20 corresponds to one pump body 10 , and one second tank body 30 corresponds to one pump body 10 .

[0058] It should be noted that each first tank body 20 stores the same type of additives, and each second tank body 30 stores the same type of liquid medium.

[0059] Figure 4 , Figure 5 and Figure 6It is a flow chart of the pump body control method provided by the present invention.

[0060] Figure 4 In the embodiment, after the pump body 10 is started, the weighing value change parameter of the material scale 40 corresponding to the pump body 10 is obtained to determine whether the pump body 10 is idling.

[0061] Figure 5 In the process, a judgment is made based on the difference between the first weighing value and the second weighing value weighed by the material scale 40 during the collection time period to determine whether the preset difference is met, and based on the judgment result, related operations such as continuous operation of the pump body 10 or pump stop alarm are performed.

[0062] Figure 6 In the present invention, when the pump body 10 is stopped for a certain period of time, due to the difference in pipeline length or pipeline routing, it is difficult for the material scale 40 to obtain the weight characteristics of the additive or liquid medium within the normal detection time. Therefore, it is necessary to judge the pump stop time. When the pump stop time is greater than 30 seconds or 12 hours, the weighing time of the material scale 40 is changed accordingly according to the corresponding detection rules, thereby ensuring the accuracy of the idling detection of the pump body 10.

[0063] Specifically, when the pump is stopped for more than 30 seconds, the first weighing value and the second weighing value are obtained according to the second time length. When the difference between the first weighing value and the second weighing value meets the preset difference, the subsequent collection time length is calculated according to the first time length.

[0064] Furthermore, when the pump is stopped for more than 12 hours, the real-time weighing value is obtained. When the difference between the real-time weighing value and the first weighing value corresponding to the first collection time period is greater than the preset difference, the end time of the first collection time period is adjusted to the time of obtaining the real-time weighing value, that is, when the pump is stopped for more than 12 hours, the first collection time period is based on the time when the weighing value is greater than 0, and this time is used as the time of obtaining the real-time weighing value, and the length between the start time and the acquisition time is used as the first collection time period, and recorded. When the pump is stopped for more than 12 hours subsequently, the first collection time period corresponding to the record is retrieved.

[0065] Furthermore, the non-first collection time period in which the pump is stopped for a period longer than 12 hours is performed according to the first period.

[0066] Figure 7 It is a structural schematic diagram of the pump body control device provided by the present invention;

[0067] Figure 8 It is a structural schematic diagram of the electronic device provided by the present invention.

[0068] The present invention will be described in detail below in conjunction with specific implementation modes.

[0069] In some specific embodiments of the present invention, Figures 1 to 6 As shown, this solution provides a pump control method, which is applied to a mixing station. The mixing station includes: a pump 10 and a material scale 40. The pump 10 is used to transport materials to the material scale 40;

[0070] Methods include:

[0071] Control the pump body 10 to start;

[0072] Obtaining a weighing value change parameter of a material scale 40 corresponding to the pump body 10;

[0073] Based on the weighing value change parameter, determine whether the pump body 10 is idling;

[0074] When it is determined that the pump body 10 is idling, the pump body 10 is controlled to stop running.

[0075] It should be noted that by judging the weighing value change parameters of the material scale 40, the loading situation of the pump body 10 can be accurately known. If the first tank body 20 and / or the second tank body 30 is short of material, the additive and / or state medium transported by the pump body 10 to the material scale 40 will have a weight deviation. Therefore, by obtaining the corresponding weighing changes of the material scale 40 of the mixing station, it is determined whether the pump needs to be stopped without the need for additional detection devices.

[0076] In a possible implementation manner, it is determined that the weight parameter of the material scale 40 does not meet the preset conditions, the pump body 10 stops feeding, and after an alarm is sounded, the alarm can be switched to manual and then to automatic to reset the alarm.

[0077] In some possible embodiments of the present invention, the step of obtaining the weighing value change parameter of the material scale 40 corresponding to the pump body 10 specifically includes:

[0078] Obtain a first weighing value and a second weighing value corresponding to each acquisition time period in N consecutive acquisition time periods;

[0079] The first weighing value is the weighing value of the material scale 40 at the start time of the corresponding collection time period, the second weighing value is the weighing value of the material scale 40 at the end time of the corresponding collection time period, and N is a positive integer.

[0080] Specifically, this embodiment provides an implementation method for obtaining the weighing value change parameters of the material scale 40 corresponding to the pump body 10. By obtaining the first weighing value and the second weighing value, it is possible to judge the weighing values ​​of the material scale 40 at the start and end times of the collection time period, and then judge whether the pump body 10 is idling.

[0081] In some possible embodiments of the present invention, the step of determining whether the pump body 10 is idling based on the weighing value change parameter specifically includes:

[0082] When the difference between the second weighing value and the first weighing value corresponding to any collection time period is less than a preset difference, it is determined that the pump body 10 is idling.

[0083] Specifically, this embodiment provides an implementation method for determining whether the weighing value change parameter meets the preset conditions, by judging the difference between the second weighing value and the first weighing value. When the difference between the second weighing value and the first weighing value is less than the preset difference, it means that the pump body 10 is idling at this time and corresponding emergency measures need to be taken.

[0084] In a possible implementation manner, when the preset difference is less than or equal to zero, it is determined that the weight parameter of the material scale 40 does not meet the preset condition.

[0085] In a possible implementation manner, when the preset difference is greater than zero, it is determined that the weight parameter of the material scale 40 meets the preset condition.

[0086] In some possible embodiments of the present invention, the N consecutive acquisition time periods include 1 first acquisition time period and N-1 non-first acquisition time periods, and the starting time of the first acquisition time period is the start time of the pump body 10;

[0087] Before obtaining the weighing value change parameter of the material scale 40 corresponding to the pump body 10, the method further includes:

[0088] Obtaining the downtime of the pump body 10 before starting;

[0089] If the downtime is less than the preset downtime, the duration of the first collection time period and the duration of the non-first collection time period are determined to be the first duration;

[0090] If the downtime duration is greater than the preset downtime duration, the duration of the first collection time period is determined to be the second duration, and the duration of the non-first collection time period is determined to be the first duration, and the second duration is greater than the first duration.

[0091] Specifically, this embodiment provides an implementation method for obtaining the downtime duration of the pump body 10 before starting. When the pump body 10 is stopped for too long, there may be a false alarm when the material scale 40 weighs due to the difference in pipeline length or pipeline route. Therefore, by obtaining the downtime duration of the pump body 10, different collection time periods are used according to different downtime durations, thereby avoiding the occurrence of false alarms after the material scale 40 weighs.

[0092] In a possible implementation manner, the first duration is between 2 seconds and 6 seconds.

[0093] In a possible implementation manner, the first duration is 4 seconds.

[0094] In a possible implementation manner, the second duration is between 15 seconds and 25 seconds.

[0095] In a possible implementation manner, the second time length is 20 seconds.

[0096] In a possible implementation manner, the preset downtime duration is between 20 seconds and 40 seconds.

[0097] In a possible implementation manner, the preset downtime duration is 30 seconds.

[0098] In some possible embodiments of the present invention, when the duration of the first acquisition time period is determined to be the second duration, and the duration of the non-first acquisition time period is determined to be the first duration, the step of obtaining the first weighing value and the second weighing value corresponding to each acquisition time period in N consecutive acquisition time periods specifically includes:

[0099] Acquire the weight value of the material scale 40 at the start time of the pump body 10 to obtain the first weighing value corresponding to the first collection time period;

[0100] During the first collection time period, obtain the real-time weighing value of the material scale 40;

[0101] When the difference between the real-time weighing value and the first weighing value corresponding to the first collection time period is greater than a preset difference, the end time of the first collection time period is adjusted to the acquisition time of the real-time weighing value, the real-time weighing value is determined as the second weighing value corresponding to the first collection time period, and based on the adjusted end time of the first collection time period and the first duration, the start time and end time of each non-first collection time period are adjusted;

[0102] Based on the adjusted start time and end time of each non-first collection time period, the first weighing value and the second weighing value corresponding to each non-first collection time period are obtained.

[0103] Specifically, this embodiment provides an implementation method for obtaining the weighing value change parameters of the material scale 40 corresponding to the pump body 10. When the shutdown time of the pump body 10 is greater than the preset shutdown time, the start time and end time of the first collection time period are used as the second time period, and the start time and end time of the non-first collection time period are adjusted according to the end time of the first collection time period and the first time period, so that the non-first collection time period can be smoothly connected with the first collection time period. After the corresponding real-time weighing value is obtained in the first collection time period, the non-first collection time period is quickly entered to collect the corresponding weighing value change parameters of the pump body 10.

[0104] In some possible embodiments of the present invention, after obtaining the real-time weighing value of the material scale 40 during the first collection time period, the method further includes:

[0105] When the difference between the real-time weighing value and the first weighing value corresponding to the first acquisition time period is greater than the preset difference, the time interval between the acquisition time of the real-time weighing value and the start time of the pump body 10 is determined;

[0106] Based on the time interval, the second duration is adjusted.

[0107] Specifically, this embodiment provides an implementation method after obtaining the real-time weighing value of the material scale 40. When the shutdown time of the pump body 10 is greater than the preset shutdown time, the time interval between the acquisition time of the real-time weighing value and the start time of the pump body 10 is obtained, and the second time interval is updated according to the time interval, so that the idling of the pump body 10 can be judged more accurately according to the shutdown time of the pump body 10, thereby avoiding the false alarm of the material scale 40 when weighing due to different pipeline lengths or pipeline routes. Therefore, by obtaining the shutdown time of the pump body 10, different collection time periods are used according to different shutdown times, thereby avoiding the occurrence of false alarms after weighing by the material scale 40.

[0108] In some possible embodiments of the present invention, when it is determined that the pump body 10 is idling, the step of controlling the pump body 10 to stop running specifically includes:

[0109] The pump body 10 is controlled to stop running, an alarm message is output, and the control mode of the pump body 10 is switched from the automatic mode to the manual mode.

[0110] Specifically, this embodiment provides an implementation method for controlling the pump body 10 to stop running. After preliminarily determining that the pump body 10 is idling, the pump body 10 is switched from automatic mode to manual mode, thereby avoiding the problem of the pump body 10 automatically starting again and avoiding damage to the pump body 10 caused by idling.

[0111] In some possible embodiments of the present invention, after controlling the pump body 10 to stop running, outputting an alarm message, and switching the control mode of the pump body 10 from the automatic mode to the manual mode, the method further includes:

[0112] When it is detected that the material tank corresponding to the pump body 10 has been refilled, the control mode of the pump body 10 is switched from the manual mode to the automatic mode.

[0113] Specifically, this embodiment provides an implementation method for switching the control mode of the pump body 10 from the automatic mode to the manual mode. By switching the control mode of the pump body 10 from the manual mode to the automatic mode, the pump body 10 can realize the loading operation after the material tank is filled.

[0125] Before obtaining the weighing value change parameter of the material scale 40 corresponding to the pump body 10, the method further includes:

[0126] Obtaining the downtime of the pump body 10 before starting;

[0127] If the downtime is less than the preset downtime, the duration of the first collection time period and the duration of the non-first collection time period are determined to be the first duration;

[0128] If the downtime duration is greater than the preset downtime duration, the duration of the first collection time period is determined to be the second duration, and the duration of the non-first collection time period is determined to be the first duration, and the second duration is greater than the first duration.
