The invention relates to an intelligent monitoring system and method for a brine mining pump. The system includes an on-site control device. The on-site control device includes: a sensor, a processing module, a control module and an execution module. The control module is used to judge according to the pretreated brine liquid level Whether the brine pump is abnormal; when it is judged that the brine pump is abnormal, calculate the target speed of the brine pump according to the pretreated brine level, output voltage and output current, and generate a control command according to the target speed. The on-site control device is installed at the site of the brine extraction well, which can adjust the speed of the brine extraction pump by itself, and does not need manual inspection to check the working status of the brine extraction pump, which reduces management costs.

When the brine extraction pump is abnormal, the control device can quickly calculate the target speed, and then adjust the operation of the brine extraction pump, so the real-time response to the abnormality is good.
Description
技术领域technical field
本发明涉及智能监控技术领域，具体涉及一种采卤泵智能监控系统及一种采卤泵智能监控方法。The invention relates to the technical field of intelligent monitoring, in particular to an intelligent monitoring system for a brine mining pump and an intelligent monitoring method for a brine mining pump.
背景技术Background technique
盐湖化工产业是青海省四大支柱产业之一，盐湖资源是青海省得天独厚的自然矿产资源。青海盐湖资源主要位于柴达木盆地，由于盐矿区地质构造的不同以及地下盐矿储量分布的不同，使得盐湖化工企业的生产场区分散，各场区之间距离由几十至几百公里不等，而不同种类盐矿的盐田分布位置相距更远。而且，负责抽取地下盐卤和输送地上盐卤的采卤设备在场区和盐田内分布零散，但数量庞大，足有上百台之多，这导致企业对采卤设备的日常管理较为困难。Salt Lake chemical industry is one of the four pillar industries in Qinghai Province, and Salt Lake resources are unique natural mineral resources in Qinghai Province. The salt lake resources in Qinghai are mainly located in the Qaidam Basin. Due to the different geological structures in the salt mine area and the distribution of underground salt mine reserves, the production sites of the salt lake chemical enterprises are scattered, and the distance between the sites varies from tens to hundreds of kilometers. etc., while the distribution of salt pans of different types of salt mines is farther apart. Moreover, the brine mining equipment responsible for extracting underground brine and transporting above-ground brine is scattered in the field and in the salt field, but the number is huge, as many as hundreds, which makes the daily management of brine mining equipment more difficult for enterprises.
目前，青海盐湖化工企业主要采用人工巡检的方式监测采卤泵的运行状况和处理故障。各盐湖化工企业每天派出很多车辆、多名检修员工全天沿线巡检，逐个查看各个场区和各个盐田上采卤设备的运行状况、故障情况和损坏率等。这种人工巡检的方式受到场区和盐田地理环境、天气环境和生产环境的制约很大，而且维护成本较大，例如人工成本、车辆油耗等。At present, Qinghai Salt Lake Chemical Company mainly uses manual inspection to monitor the operation status of brine pumps and deal with faults. Each salt lake chemical company dispatches a lot of vehicles every day, and a number of maintenance staff patrol along the line throughout the day to check the operation status, failure status and damage rate of brine mining equipment in each field and each salt field one by one. This manual inspection method is greatly restricted by the geographical environment of the site and Yantian, the weather environment and the production environment, and the maintenance cost is relatively high, such as labor costs and vehicle fuel consumption.
而且，负责抽取地下盐卤的采卤设备一般为潜水电泵，由于潜水电泵安装在地面以下，所以很难记录潜水电泵的运行相关参数，仅能凭经验判断。但是经验判断容易出现误判或漏判，准确性较差。Moreover, the brine extraction equipment responsible for extracting underground brine is generally a submersible electric pump. Since the submersible electric pump is installed below the ground, it is difficult to record the relevant parameters of the operation of the submersible electric pump, and it can only be judged by experience. However, empirical judgments are prone to misjudgments or missed judgments, and the accuracy is poor.
另外，当发现设备异常或故障，也只能暂且停机处理，需要专业维修人员再次响应，实时性较差。而且，目前只能通过手动操作设备配电柜上的按钮开关来控制采卤设备的启动与停止。一般一个配电柜给三台采卤设备供电，有三套按钮开关分别控制三台采卤设备。这种控制方法不能在采卤设备发生异常时第一时间停止设备，有可能导致采卤设备烧毁，为企业生产带来了巨大的损失。In addition, when an abnormality or failure of the equipment is found, it can only be temporarily shut down for processing, requiring professional maintenance personnel to respond again, and the real-time performance is poor. Moreover, at present, the start and stop of the brine mining equipment can only be controlled by manually operating the button switch on the equipment power distribution cabinet. Generally, one power distribution cabinet supplies power to three brine mining equipment, and there are three sets of button switches to control the three brine mining equipment respectively. This control method cannot stop the equipment at the first time when the brine mining equipment is abnormal, which may cause the brine mining equipment to be burned, which has brought huge losses to the production of the enterprise.
总之，目前盐湖化工企业对采卤设备的管理成本高、异常或故障判断准确性差、对异常或故障的响应实时性差，使得盐湖化工企业对于数量庞大的采卤设备的管理尤为困难。In short, at present, salt lake chemical companies have high management costs for brine mining equipment, poor accuracy of abnormal or fault judgment, and poor real-time response to abnormal or faults, making it particularly difficult for salt lake chemical companies to manage a large number of brine mining equipment.

本发明提供了一种采卤泵智能监控系统，如图1所述，该系统包括现场控制装置，所述现场控制装置包括：The present invention provides an intelligent monitoring system for a brine mining pump. As shown in FIG. 1, the system includes an on-site control device, and the on-site control device includes:
传感器，用于采集采卤井内的卤水液位、采卤泵的输出电压及采卤泵的输出电流；The sensor is used to collect the brine level in the brine well, the output voltage of the brine pump and the output current of the brine pump;

其中，传感器为多个，用来采集不同的数据。Wherein, there are multiple sensors, which are used to collect different data.
其中，处理模块为对传感器采集的数据进行预处理，预处理的方式有多种，这里不做限定，例如剔除其中由于传感器测量误差导致的异常数据，因为传感器在采集数据时，有可能由于自身因素导致数据异常，而并非采集到的数据本身就异常，所以需要剔除这些由于采集或测量误差导致的异常数据，以提高采卤泵调节的准确性。Among them, the processing module is to preprocess the data collected by the sensor. There are many ways of preprocessing, which are not limited here. Factors lead to abnormal data, rather than the collected data itself is abnormal, so it is necessary to eliminate these abnormal data caused by collection or measurement errors to improve the accuracy of brine extraction pump adjustment.

Since the on-site control device judges whether the brine extraction pump is abnormal through the collected data instead of manual judgment, it has high accuracy. In addition, when the brine extraction pump is abnormal, the control device can quickly calculate the target speed, and then adjust the operation of the brine extraction pump, so the real-time response to the abnormality is good. Through the above analysis, the present invention can greatly reduce the management difficulty of the brine extraction pump.

虽然现场控制装置可以自行调节采卤泵的工作，但在某些情况下工作人员需要进行人工干预。这里，通过监控单元输入工作人员需要人工干预的控制指令，当监控单元接收到该控制指令时，通过远程通信模块发送给现场控制装置的控制模块，控制模块再将该控制指令发送给执行模块，执行模块执行该控制指令，进而调节采卤泵的转速。Although the on-site control device can adjust the work of the brine extraction pump by itself, in some cases, the staff needs to intervene manually. Here, the monitoring unit inputs a control command requiring manual intervention by the staff. When the monitoring unit receives the control command, it sends it to the control module of the on-site control device through the remote communication module, and the control module sends the control command to the execution module. The execution module executes the control instruction, and then adjusts the speed of the brine extraction pump.
由于控制模块根据现场采集的数据会生成一控制指令，当执行模块在收到控制模块生成的控制指令的同时，也收到了工作人员需要人工干预的控制指令，此时要执行工作人员需要人工干预的控制指令。即人工输入的控制指令的优先级要高于控制模块根据现场数据生成的控制指令。Since the control module will generate a control command based on the data collected on site, when the execution module receives the control command generated by the control module, it also receives the control command that requires manual intervention from the staff. At this time, the staff needs manual intervention to execute control instructions. That is, the priority of the control command input manually is higher than the control command generated by the control module according to the field data.
远程通信模块为现场控制装置与远程监控装置之间的桥梁，用于远距离传输数据，将现场控制装置中的有关数据传送至远程监控装置，也可以将远程监控装置的控制质量传送给现场控制装置。The remote communication module is a bridge between the on-site control device and the remote monitoring device, used for long-distance data transmission, the relevant data in the on-site control device to the remote monitoring device, and the control quality of the remote monitoring device to the on-site control device.
远程通信模块为一总控制平台，可以直观的向办公楼工作人员显示系统的运行情况，工作人员也可以通过该总控制平台将控制指令传送给现场控制装置。该控制平台可具有良好的人机交互界面，并可采用Web网页的形式实现显示功能。当然，通过建立局域网的方式，还可以实现智能手机、平板电脑、个人计算机等访问服务平台实现监测与控制。The remote communication module is a general control platform, which can intuitively display the operation status of the system to the office building staff, and the staff can also transmit control instructions to the on-site control device through the general control platform. The control platform can have a good human-computer interaction interface, and can realize the display function in the form of a Web page. Of course, by establishing a local area network, access to service platforms such as smartphones, tablet computers, and personal computers can also be monitored and controlled.
可选的，所述远程监控装置还可包括：Optionally, the remote monitoring device may also include:
存储单元，用于存储所述卤水液位、所述输出电压、所述输出电流及所述目标转速。The storage unit is used to store the brine level, the output voltage, the output current and the target rotational speed.
远程监控装置利用存储单元将有关数据进行存储，以便后续对数据的分析、统计等工作。The remote monitoring device uses the storage unit to store relevant data for subsequent data analysis and statistics.
可见，可以利用存储单元存储历史数据或实时数据。It can be seen that the storage unit can be used to store historical data or real-time data.
本发明还提供一种采卤泵智能监控方法，如图2所示，该方法包括：The present invention also provides an intelligent monitoring method for a brine mining pump, as shown in Figure 2, the method includes:
S1、采集采卤井内的卤水液位、采卤泵的输出电压及采卤泵的输出电流；S1. Collect the brine liquid level in the brine extraction well, the output voltage of the brine extraction pump and the output current of the brine extraction pump;
S2、对采集到的所述卤水液位、所述输出电压及所述输出电流进行预处理；S2. Preprocessing the collected brine liquid level, the output voltage and the output current;
S3、根据预处理后的所述卤水液位判断所述采卤泵是否出现异常；S3, judging whether the brine extraction pump is abnormal according to the pretreated brine liquid level;
S4、在判定采卤泵出现异常时，根据预处理后的所述卤水液位、所述输出电压及所述输出电流，计算采卤泵的目标转速，并根据所述目标转速生成控制指令；S4. When it is determined that the brine extraction pump is abnormal, calculate the target speed of the brine extraction pump according to the pretreated brine liquid level, the output voltage and the output current, and generate a control instruction according to the target speed;
S5、根据所述控制指令，调节采卤泵的转速。S5. Adjust the rotational speed of the brine extraction pump according to the control instruction.
本发明提供了一种基于采卤泵智能监控系统的采卤泵智能监控方法，该方法实现了采卤泵转速的自动调节，此不需要人工巡检查看采卤泵的工作状态，减少了管理成本。该方法通过现场采集的有关数据判断采卤泵是否异常，而并非通过人工经验判断，因此具有较高的准确性。另外，在采卤泵异常时，能够及时的计算目标转速，进而调节采卤泵的运行，因此对异常的响应实时性好。通过以上分析，利用本发明可以大大减小对采卤泵的管理难度。The present invention provides a brine pump intelligent monitoring method based on the brine pump intelligent monitoring system. The method realizes the automatic adjustment of the brine pump speed, which does not require manual inspection to see the working status of the brine pump, reducing management cost. The method judges whether the brine extraction pump is abnormal based on the relevant data collected on site, rather than through manual experience, so it has high accuracy. In addition, when the brine pump is abnormal, the target speed can be calculated in time, and then the operation of the brine pump can be adjusted, so the real-time response to the abnormality is good. Through the above analysis, the present invention can greatly reduce the management difficulty of the brine extraction pump.
在具体实施过程中，所述步骤S1可包括：按照预设周期采集卤水液位、采卤泵的输出电压及采卤泵的输出电流；In the specific implementation process, the step S1 may include: collecting the brine liquid level, the output voltage of the brine extraction pump and the output current of the brine extraction pump according to a preset period;
所述步骤S2可包括：The step S2 may include:
判断当前周期采集到的相应数据在相应的预设范围内，Judging that the corresponding data collected in the current cycle is within the corresponding preset range,
若是，则保留当前周期采集到的相应数据；If so, keep the corresponding data collected in the current cycle;
否则，判断包括当前周期在内的连续的至少三个周期内采集到的相应数据是否均超出相应的预设范围，Otherwise, judge whether the corresponding data collected in at least three consecutive cycles including the current cycle exceed the corresponding preset range,
若是，则保留当前周期内采集到的相应数据；If so, keep the corresponding data collected in the current cycle;
否则，将当前周期内采集到的相应数据剔除；Otherwise, delete the corresponding data collected in the current period;
其中，所述相应数据为所述卤水液位、所述输出电压或所述输出电流。Wherein, the corresponding data is the brine liquid level, the output voltage or the output current.
这里，步骤S2中若采集到的相应数据在相应的预设范围，则说明采集到的数据正常，若采集到的相应数据超出了相应的预设范围，则说明采集到的数据异常。数据异常有两种情况，第一种是由于传感器的采集误差导致的，第二种是采卤泵出现异常，导致相关的数据异常。对于第一种情况下采集的数据有可能导致采卤泵运行状态的错误判断，进而影响对采卤泵的调节，因此需要剔除。Here, if the corresponding data collected in step S2 is within the corresponding preset range, it means that the collected data is normal, and if the corresponding collected data exceeds the corresponding preset range, it means that the collected data is abnormal. There are two cases of data abnormality, the first one is caused by the acquisition error of the sensor, and the second one is the abnormality of the brine extraction pump, which leads to related data abnormalities. The data collected in the first case may lead to wrong judgment of the operation status of the brine extraction pump, and then affect the adjustment of the brine extraction pump, so it needs to be eliminated.
剔除过程首先需要判断采集的数据属于哪一种情况。这里通过步骤S1中周期性采集相关数据的方式，根据在多个周期中采集到的数据进行判断。在判断当前周期采集到的相关数据时，判断包括当前周期在内的连续的至少三个周期内采集到的相关数据是否都异常，若都异常，则说明采卤泵真的出现了异常，否则认为当前出现的异常数据属于第一种情况，需要剔除。The elimination process first needs to determine which situation the collected data belongs to. Here, the judgment is made based on the data collected in multiple cycles by periodically collecting relevant data in step S1. When judging the relevant data collected in the current cycle, judge whether the relevant data collected in at least three consecutive cycles including the current cycle are abnormal. If they are abnormal, it means that the brine extraction pump is really abnormal, otherwise It is considered that the current abnormal data belongs to the first situation and needs to be eliminated.
下面以一实例对上述过程进行说明：The above process is described below with an example:
当在第n个周期内采集到数据异常时，When abnormal data is collected in the nth cycle,
若第n-1个周期内采集到的数据正常，则等待第n+1个周期采集相关数据，若第n+1个周期采集到的数据正常，则剔除第n个周期内采集到的数据；If the data collected in the n-1th cycle is normal, wait for the n+1th cycle to collect relevant data, if the data collected in the n+1th cycle is normal, remove the data collected in the nth cycle ;
若第n-1个周期内采集到的数据正常，则等待第n+1个周期采集相关数据，若第n+1个周期采集到的数据异常，则等待第n+2个周期内采集相关数据，若第n+2个周期内采集到的数据正常，则剔除第n个周期内采集到的数据；If the data collected in the n-1th cycle is normal, wait for the n+1th cycle to collect relevant data, if the data collected in the n+1th cycle is abnormal, wait for the n+2th cycle to collect relevant data Data, if the data collected in the n+2th cycle is normal, the data collected in the nth cycle will be eliminated;
若第n-1个周期内采集到的数据正常，则等待第n+1个周期采集相关数据，若第n+1个周期采集到的数据异常，则等待第n+2个周期内采集相关数据，若第n+2个周期内采集到的数据异常，则保留第n个周期内采集到的数据；If the data collected in the n-1th cycle is normal, wait for the n+1th cycle to collect relevant data, if the data collected in the n+1th cycle is abnormal, wait for the n+2th cycle to collect relevant data Data, if the data collected in the n+2th cycle is abnormal, keep the data collected in the nth cycle;
若第n-1个周期内采集到的数据异常，则等待第n+1个周期采集相关数据，若第n+1个周期采集到的数据异常，则保留第n个周期内采集到的数据；If the data collected in the n-1th cycle is abnormal, wait for the n+1th cycle to collect relevant data, if the data collected in the n+1th cycle is abnormal, keep the data collected in the nth cycle ;
若第n-1个周期内采集到的数据异常，则等待第n+1个周期采集相关数据，若第n+1个周期采集到的数据正常，则剔除第n个周期内采集到的数据或者查看第n-2个周期内采集到的数据进一步判断。If the data collected in the n-1th cycle is abnormal, wait for the n+1th cycle to collect relevant data, if the data collected in the n+1th cycle is normal, delete the data collected in the nth cycle Or check the data collected in the n-2th cycle for further judgment.
当一个周期内采集的数据出现异常，需要后续周期内的数据进行辅助判断时，需要等待下一周期或下下周期。在预处理完成后保留当前周期内采集到的数据时再执行后续的步骤。在当前周期内的相关数据被剔除后，就没必要利用该数据进行后续的判断计算、调速等步骤了。When the data collected in one cycle is abnormal and the data in the subsequent cycle is needed for auxiliary judgment, it is necessary to wait for the next cycle or the next cycle. After the preprocessing is completed, the data collected in the current cycle is retained before performing subsequent steps. After the relevant data in the current cycle is eliminated, there is no need to use the data for subsequent steps such as judgment calculation and speed regulation.
可选的，所述步骤S3可包括：Optionally, the step S3 may include:
判断采卤井深度与预处理后的所述卤水液位之间的差值与第一距离、第二距离的大小关系，Judging the relationship between the difference between the depth of the brine extraction well and the pretreated brine liquid level and the first distance and the second distance,
若所述差值大于所述第二距离且小于所述第一距离，则判定所述采卤泵正常；If the difference is greater than the second distance and less than the first distance, it is determined that the brine extraction pump is normal;
若所述差值大于或等于所述第一距离，或者所述差值小于或等于所述第二距离，则判定所述采卤泵异常；If the difference is greater than or equal to the first distance, or the difference is less than or equal to the second distance, it is determined that the brine pump is abnormal;
其中，所述第一距离为采卤泵入水口与采卤井口之间的距离，第二距离为卤水液面与采卤井口之间的安全距离。Wherein, the first distance is the distance between the water inlet of the brine extraction pump and the brine extraction wellhead, and the second distance is the safe distance between the brine liquid level and the brine extraction wellhead.
所谓的安全距离，是指保证卤水不会溢出时的卤水液面与采卤井口之间的最小距离。The so-called safe distance refers to the minimum distance between the brine liquid level and the brine mining wellhead when the brine will not overflow.
一般情况下，采卤井深度在30-35之间，安全距离在3米左右，第一距离为27米左右。Under normal circumstances, the depth of the brine extraction well is between 30-35, the safe distance is about 3 meters, and the first distance is about 27 meters.
本发明提供了一种根据卤水液位判断采卤泵是否异常的方法。如图3所示，这里将采卤井深度与预处理后的所述卤水液位之间的差值用h表示，第一距离用H1表示，第二距离用H2表示，则判定所述采卤泵正常的不等式可表示为H2<h<H1；判定所述采卤泵异常的不等式可以表示为h>＝H1或h<＝H2。The invention provides a method for judging whether a brine extraction pump is abnormal according to the brine liquid level. As shown in Figure 3, the difference between the brine extraction well depth and the pretreated brine liquid level is represented by h here, the first distance is represented by H1, and the second distance is represented by H2, then it is determined that the The inequality for the normality of the brine pump can be expressed as H2<h<H1; the inequality for determining the abnormality of the brine extraction pump can be expressed as h>=H1 or h<=H2.
当H2<h<H1时，说明此时采卤泵处于正常工作状态，不需要进行调速控制；When H2<h<H1, it means that the brine extraction pump is in normal working state at this time, and speed control is not needed;
当h>＝H1时，说明此时采卤泵转速过快，导致卤水液位下降过快，采卤泵陷入空转的异常运行状态，此时需要根据卤水液位、输出电压和输出电流计算目标转速，该目标转速应小于采卤泵的当前转速；When h>=H1, it means that the speed of the brine extraction pump is too fast at this time, causing the brine liquid level to drop too fast, and the brine extraction pump falls into an abnormal operation state of idling. At this time, the target needs to be calculated according to the brine liquid level, output voltage and output current Speed, the target speed should be less than the current speed of the brine extraction pump;
当h<＝H2时，说明此时采卤泵处于转速过慢，导致卤水液位上升过快的异常运行状态，需要根据卤水液位、输出电压和输出电流计算目标转速，该目标转速应大于采卤泵的当前转速。When h<=H2, it means that the brine extraction pump is in an abnormal operating state where the speed is too slow, causing the brine liquid level to rise too fast. It is necessary to calculate the target speed according to the brine liquid level, output voltage and output current. The target speed should be greater than The current speed of the brine extraction pump.
经过多个周期的转速调节后，可使采卤泵处于较佳的工作状态。After several cycles of speed adjustment, the brine extraction pump can be in a better working condition.
可选的，所述步骤S4可包括：Optionally, the step S4 may include:
在判定采卤泵为异常时，确定预处理后的所述卤水液位、所述输出电压的等级及所述输出电流的等级；When it is determined that the brine extraction pump is abnormal, determine the pretreated brine liquid level, the level of the output voltage, and the level of the output current;
根据所述卤水液位的等级、所述输出电压的等级及所述输出电流的等级，确定采卤泵的目标转速等级；According to the level of the brine liquid level, the level of the output voltage and the level of the output current, determine the target speed level of the brine extraction pump;
根据所述目标转速等级，确定所述目标转速。The target rotational speed is determined according to the target rotational speed level.
这里，卤水液位的等级是根据卤水液位所在的预设范围决定的，当卤水液位落在某个预设范围内，其等级就为该范围对应的等级。输出电压、输出电流的等级也是这样确定的。Here, the grade of the brine liquid level is determined according to the preset range where the brine liquid level is located, and when the brine liquid level falls within a certain preset range, the grade is the grade corresponding to the range. The level of output voltage and output current is also determined in this way.
根据卤水液位的等级、输出电压的等级及输出电流的等级确定目标转速等级的方法，可以预先根据先验知识分析出卤水液位的等级、输出电压的等级、输出电流的等级与目标转速等级之间的确定关系，然后根据该确定关系确定目标转速等级。The method of determining the target speed level according to the level of the brine level, the level of the output voltage and the level of the output current can be analyzed in advance according to the level of the brine level, the level of the output voltage, the level of the output current and the level of the target speed. The determined relationship between them, and then determine the target speed level according to the determined relationship.
具体可以将卤水液位的等级、输出电压的等级或输出电流的等级分为低、中、高三个等级，目标转速等级分为零、低、中、高四个等级，其中零对应着关闭采卤泵。Specifically, the level of brine liquid level, output voltage or output current can be divided into three levels: low, medium, and high; the target speed level can be divided into four levels: zero, low, medium, and high; brine pump.
当卤水液位的等级分别为低、中、高时，输出电压的等级、输出电流的等级及目标转速的等级之间的确定关系可采用下表1、表2、表3表示：When the grades of the brine liquid level are low, medium and high, the determined relationship between the grades of the output voltage, the grade of the output current and the grade of the target speed can be expressed in Table 1, Table 2 and Table 3 below:
表1 当卤水液位的等级为低时的确定关系表Table 1 Determination relationship table when the brine level is low
表2 当卤水液位的等级为中时的确定关系表Table 2 Determination relationship table when the level of brine level is medium
表3 当卤水液位的等级为高时的确定关系表Table 3 Determination relationship table when the level of brine level is high
在根据先验知识得到以上三个表格后，卤水液位的等级、输出电压的等级、输出电流的等级这三个等级之间的任意组合均对应一个目标转速等级，然后便可以根据目标转速等级确定目标转速。After obtaining the above three tables based on prior knowledge, any combination of the three levels of brine level, output voltage, and output current corresponds to a target speed level, and then the target speed level can be Determine the target speed.
可选的，该方法还可包括：Optionally, the method may also include:
将预处理后的所述卤水液位、所述输出电压、所述输出电流和/或计算得到的所述目标转速发送至远程监控装置；Sending the pretreated brine liquid level, the output voltage, the output current and/or the calculated target speed to a remote monitoring device;
接收所述远程监控装置发送的控制指令；receiving a control instruction sent by the remote monitoring device;
在根据所述目标转速生成控制指令的同时接收到所述远程监控装置发送的控制指令时，根据所述远程监控装置发送的控制指令调节采卤泵的转速。When the control instruction sent by the remote monitoring device is received while the control instruction is generated according to the target rotating speed, the rotating speed of the brine extraction pump is adjusted according to the control instruction sent by the remote monitoring device.
这里，可将有关的数据发送至远程监控装置上，利用该远程监控装置对现场采卤泵的运行进行监控，同时，利用该远程监控装置还可以发送工作人员进行人为干预的控制指令。Here, the relevant data can be sent to the remote monitoring device, which can be used to monitor the operation of the on-site brine extraction pump. At the same time, the remote monitoring device can also be used to send control instructions for human intervention by the staff.
当根据所述目标转速生成控制指令的同时接收到所述远程监控装置发送的控制指令时，根据所述远程监控装置发送的控制指令调节采卤泵的转速。When the control instruction is generated according to the target rotational speed and the control instruction sent by the remote monitoring device is received, the rotational speed of the brine extraction pump is adjusted according to the control instruction sent by the remote monitoring device.
可见，人为干预的控制指令的优先级要高于根据现场采集的数据生成的控制指令的优先级。It can be seen that the priority of the control instruction of human intervention is higher than that of the control instruction generated according to the data collected on site.
