All other embodiments, which can be made by one of ordinary skill in the art based on the embodiments herein without making any inventive effort, are intended to be within the scope of the present application.
The following terms are used herein.
CRC refers to cyclic redundancy check code, which is a common check code with error detection and correction capability and is commonly used for data check of synchronous communication between an external memory and a computer.
NPOI refers to a program built on top of POI 3.X version, and NPOI can perform read-write operation on Word or Excel document without Office installation.
Example 1
The first embodiment of the application provides a monitoring method based on a mass flowmeter, which is applied to terminal equipment, wherein the terminal equipment is in communication connection with the mass flowmeter; as shown in fig. 1, the method may include the steps of:
step S101, detecting whether the received configuration parameters are matched with a target serial port;
step S102, if the configuration parameters are matched with a target serial port, acquiring target parameter information of the mass flowmeter;
step S103, loading the target parameter information to a preset control, so that the preset control displays the target parameter information in real time;
step S104, if a remote control instruction sent based on the target parameter information is received, the remote control instruction is acted on the mass flowmeter.
The monitoring method based on the mass flowmeter is integrated in a certain software product, and the software product is installed in the terminal equipment. In some examples, the terminal device and the mass flowmeter may be communicatively connected via a communication line or a wireless network; the terminal device can be, but is not limited to, an electronic device with a display screen, such as a mobile phone, a tablet computer and the like. In some examples, if the communication between the terminal device and the mass flowmeter is normal, the communication sign of the software product prompt is green, and if the communication between the terminal device and the mass flowmeter is abnormal, the communication sign of the software product prompt is red.
It should be noted that, the software product itself has functions of user login, logout, etc., so that it is convenient to manage.
Specifically, in some examples, in the step S101, when a software product installed in the terminal device is started, a user name and a user authority of a current user may be acquired first, and whether the user qualifies for monitoring the mass flowmeter is determined based on the user name and the user authority; if so, after receiving the configuration parameters, further detecting whether the received configuration parameters are matched with the target serial port.
Further, in some examples, in the step S101, if the user qualifies for monitoring the mass flowmeter, the software product may perform an initialization operation, during which the software product may first determine whether the terminal device includes an available serial port, and if the terminal device does not have an available serial port, send a prompt message, such as "This machine does not have serial port-! "etc. If the terminal equipment comprises available serial ports, one serial port in the available serial ports is determined to be a target serial port, and then the software product detects whether the received configuration parameters are matched with the target serial port after receiving the configuration parameters input by related personnel. Here, it should be noted that, because the target serial port may have modification, for example, the original target serial port is a COM1 interface, and the current target serial port is a COM2 interface, if the related personnel still input the configuration parameters of COM1, the received configuration parameters are not matched with the configuration parameters of the current target serial port COM2, and only when the related personnel input the configuration parameters of the current target serial port, that is, the configuration parameters of the COM2 interface, the received configuration parameters are matched with the target serial port.
Wherein the configuration parameters may include, but are not limited to: serial port name, baud rate, data bits, check bits, stop bits, communication address, etc.
Further, in some examples, in the step S102, if the configuration parameter matches the target serial port, the target parameter information of the mass flowmeter is obtained. In some examples, a preset time interval, such as 5s, may be preset, and then the obtained target parameter information of the mass flowmeter is saved every 5 s. For example, the data can be stored in an Access database for later inquiry.
In some embodiments of the present application, the target parameter information may include, but is not limited to, conventional parameters, internal parameters, and parameter information affecting the internal parameters, such as mass flow rate, total mass, volume flow rate, total volume, density, medium temperature, output current, output pulse, sensor frequency, sensor left side coil voltage, sensor right side coil voltage, driving voltage, time difference, oscillation period, temperature of the internal circuit board. The specific content of the target parameter information may be adjusted accordingly according to the actually required variation, including adding or subtracting some or some content of the target parameter information, which is not limited herein.
In the related art, some upper computers may obtain related parameters of the mass flowmeter, but may only obtain conventional parameters such as medium temperature and density, but may not obtain internal parameters of the mass flowmeter and parameter information affecting the internal parameters. In the scheme provided by the embodiment of the application, the target parameter information of the mass flowmeter can be comprehensively obtained through the target serial port, so that the monitoring accuracy is improved.
Further, in some examples, in the step S103, the target parameter information is loaded to a preset control, so that the preset control displays the target parameter information. Therefore, when the mass flowmeter is obtained to generate data change based on the target parameter information, the preset control synchronously displays the data change generated by the target parameter information. That is, the target parameter information and the preset control have a binding relationship, at this time, because the terminal device can directly display the target parameter information and the data change generated based on the target parameter information, it is not necessary for related personnel to perform frequent operations on the mass flowmeter to obtain the corresponding target parameter information, so that the related personnel can monitor the mass flowmeter conveniently, and the monitoring efficiency of the mass flowmeter can be improved.
Further, in some examples, in step S104, if a remote control instruction sent based on the target parameter information is received, the remote control instruction is applied to the mass flowmeter, so that remote control of the mass flowmeter is achieved, and the mass flowmeter does not need to be directly controlled manually, so that the technical problem that monitoring of the mass flowmeter by related personnel is inconvenient and the workload of the related personnel is increased due to severe installation positions of some mass flowmeters or external conditions of the use environment is skillfully avoided, and the monitoring efficiency of the mass flowmeter can be improved by the method provided by the embodiment of the application.
Specifically, in some examples, the specific content of the remote control instruction may be an instruction issued by a related person according to the target parameter information, the actual requirement and the like, and the purpose of modifying some parameters inside the mass flowmeter is to say, the content of the remote control instruction representation may be, but is not limited to, zero calibration, simulation output, accumulated amount removal, moisture analysis switch, multi-point correction and the like.
In some examples, after receiving the remote control instruction, the authority of the user sending the remote control instruction can be verified first, and if and only if the authority verification of the user passes, a corresponding operation is executed according to the remote control instruction; otherwise, the response to the remote manipulation instruction may be denied.
It is not difficult to find that, compared with the related art, the monitoring method based on the mass flowmeter provided by the embodiment of the application is applied to terminal equipment, the terminal equipment is in communication connection with the mass flowmeter, whether the received configuration parameters are matched with a target serial port or not is detected, and if the configuration parameters are matched with the target serial port, the target parameter information of the mass flowmeter is acquired; the target parameter information is loaded to a preset control, so that the preset control displays the target parameter information in real time, and as the terminal equipment can directly display the target parameter information and the data change based on the target parameter information, related personnel can check a plurality of target parameter information at one time, intuitively check the working data of the instrument to determine the working state of the instrument, and the related personnel are not required to frequently operate the mass flowmeter to acquire the corresponding target parameter information; if a remote control instruction sent based on the target parameter information is received, the remote control instruction acts on the mass flowmeter, and the mass flowmeter is controlled directly without manual operation through remote control of the mass flowmeter, so that the technical problems that monitoring and modification of the mass flowmeter are inconvenient for related personnel and the workload of the related personnel is increased due to the fact that the installation positions of some mass flowmeters or the external conditions of the use environment are harsh are avoided ingeniously, and in sum, the monitoring efficiency of the mass flowmeter can be improved by the method provided by the embodiment of the application.
Example two
The second embodiment of the present application is an improvement made on the basis of the first embodiment, and the specific improvement is that: in a second embodiment of the present application, before the loading the target parameter information to the preset control, so that the preset control displays the target parameter information, the method may further include the following steps, as shown in fig. 2:
step S201, providing a unit selection interface based on the target parameter information;
step S202, after receiving a unit modification instruction sent based on the unit selection interface, converting the numerical value of target parameter information indicated by the unit modification instruction according to a target unit represented by the unit modification instruction;
correspondingly, the loading the target parameter information to a preset control, so that the preset control displays the target parameter information includes: and loading the target parameter information subjected to the conversion processing to a preset control, so that the preset control displays the target parameter information.
Specifically, in some examples, in the step S201, the unit selection interface may be located behind the specific numerical value of each parameter in the target parameter information in the form of a drop-down box.
Specifically, in some examples, in the step S202, the unit modification instruction may be, but is not limited to, a unit modification instruction issued for a unit of mass flow rate, a unit of volume flow rate, and a unit of density. For example, in some examples, the unit requirement of the relevant user for the volume flow rate is gal (us)/sec, which is the target unit, and the default unit of the current volume flow rate is gal (imp)/sec, the value of the target parameter information may be converted according to a conversion rule of 1gal (imp)/sec=4.546l 1gal (us)/sec according to the target unit and the default unit. And correspondingly, loading the target parameter information subjected to the conversion processing to a preset control, so that the preset control displays the target parameter information, and thus, the personalized requirement of related users on units of the target parameter information can be met without manually carrying out the conversion processing of the units by the related users, and the monitoring efficiency of the mass flowmeter can be further improved.
It should be noted that, in some other examples, the default unit of the target parameter information may be a default unit, that is, a national standard measurement mode, for example, the weight unit is Kg, the volume unit is L, and the density unit is m/t. However, for this reason, it is very inconvenient for some special-demand customers or some foreign customers to use based on custom reasons, and for this reason, the monitoring method based on mass flowmeter provided in the embodiment of the present application can implement flexible conversion processing for the unit of the target parameter information through the software algorithm installed in the terminal device, which is beneficial to further improving the monitoring efficiency of the mass flowmeter.
Example III
The third embodiment of the present application is an improvement made on the basis of the first embodiment, and the specific improvement is that: in a third embodiment of the present application, a read operation and a write operation are performed respectively based on the target serial port, so as to obtain target parameter information of the mass flowmeter;
the method specifically adopts a polling mode to execute the reading operation, and the corresponding method can comprise the following steps:
a first time reading of bytes with a starting address of 11 and a length of 3;
a second time reading the bytes with a starting address of 27 and a length of 1;
a third time of reading a byte with a starting address of 82 and a length of 1;
reading bytes with a starting address of 0 and a length of 6 for the fourth time;
a fifth time of reading the bytes with a starting address of 12 and a length of 13;
a sixth time reads a byte with a start address 520 and a length of 1;
a seventh time of reading the bytes with a starting address of 100 and a length of 68;
an eighth time of reading the bytes with a starting address of 168 and a length of 62;
a ninth time of reading the byte with the initial address of 256 and the length of 20;
the tenth reading of bytes with a starting address of 450 and a length of 2, so far, the polling is continued and the step of executing the bytes … … with a starting address of 11 and a length of 3 is performed again, which is beneficial to ensuring the integrity of the read data.
Specifically, in some examples, when a read operation is performed, a read command is issued, and when the write command is prohibited, the terminal device may receive the byte data read from the mass flowmeter and further perform CRC check on the byte data, and if the result of the CRC check is that the byte data passes, update the data after processing the byte data and save the data; if the CRC check result is failure, the corresponding error data is discarded, so that the accuracy of the acquired data can be improved. And sending a write command when writing operation is performed, and sending the corresponding data to the terminal equipment at the moment so that the terminal equipment can display the corresponding data.
In some embodiments of the present application, before the performing a read operation and a write operation based on the target serial port to obtain target parameter information of the mass flowmeter, the method may further include: after receiving the trigger instruction, starting a circulation timer; acquiring constraint time of the cycle timer; and respectively executing a read operation and a write operation based on the target serial port according to the constraint time of the circulation timer so as to acquire the target parameter information of the mass flowmeter.
In particular, in some examples, the triggering instruction may be issued by a person associated with triggering a certain button of the software product, such as the Connect button.
Specifically, in some examples, the loop timer may decompose the data read by performing the read operation for each cycle, for example, perform floating point processing, integer processing, double integer processing, and the like, and store the processed data in background variables, where there is a correspondence between the background variables and the target parameter information displayed at the front end, so that the data variable of the mass flowmeter based on the target parameter information may be obtained by automatically updating page data.
Further, in some examples, the method further includes a communication interrupt and communication resume function during the performing of the read operation in accordance with the polling mode. For example, the communication resume time may be 1 hour, and if the number of times of data read by each read command packet under the read operation exceeds 4 times, the communication is interrupted to suspend the operation of data read by the command packet, and after 1 hour, the communication is automatically attempted to resume to start the operation of data read by the command packet.
Further, in some embodiments of the present application, the starting the cycle timer after receiving the trigger instruction may include: after receiving a trigger instruction, scanning the target serial port to judge whether the target serial port exists or not; if the target serial port exists, starting a circulation timer; if the target serial port does not exist, the process ends. Therefore, the situation that a series of follow-up operations are meaningless caused by the interruption of the circuit corresponding to the target serial port, such as pulling out the circuit, can be avoided, and the purpose of stopping damage in time is achieved.
It should be noted that, the embodiment of the present application may be an improvement based on the second embodiment.
Example IV
The fourth embodiment of the present application is an improvement made on the basis of the first embodiment, and the specific improvement is that: in a fourth embodiment of the present application, after the remote control instruction is applied to the mass flowmeter if the remote control instruction sent based on the target parameter information is received, the method further includes: generating an operation log;
wherein the operation log at least comprises any one or any combination of the following: the run time of the method, the operational event, the ID of the mass flow meter.
In some examples, the oplog may also include process variations based on the mass flowmeter. It will be appreciated that process variations tend to affect the accuracy of the mass flowmeter measurements, but this technical problem is often difficult to find in practical applications. By updating the process variation together into the operation log, the calculation problem that the process variation is often difficult to find in practical application can be solved.
In some other examples, the health usage trend of the mass flowmeter over the full life cycle may also be recorded.
It should be noted that, the embodiments of the present application may be modifications based on the second embodiment and/or the third embodiment.
Compared with the related art, the monitoring method based on the mass flowmeter provided by the embodiment of the application can solve the technical problem that in the related art, the change of the target parameter information of the mass flowmeter, such as the change of the target parameter information caused by manual modification, is difficult to discover by generating the operation log for related personnel to check, and can reduce the deviation of final metering settlement data.
Example five

and if the export instruction is received, exporting a data list according to the export instruction.
Specifically, in some examples, the relevant personnel may query and filter the required data according to the ID of the mass flowmeter, and issue an export instruction according to the data screened by the query, so that the software product may export a data list according to the export instruction, for example, the data list may be an Excel-form data list.
In some other examples, the derived data list may be NPOI. It can be understood that if Excel is used to derive data, a lot of time is often consumed when the amount of data to be derived is large, and a thread is easy to "die off. It was found through experimentation that the speed of data derivation by NPOI was approximately several hundred times higher than the speed of data derivation using Excel form.
It should be noted that the embodiments of the present application may be modifications based on any one or more of the second to fourth embodiments.
