The viscosity of the lubricating oil refers to the ability of the lubricating oil to maintain its viscosity in various high and low temperature environments, reflecting the resistance of the lubricating oil to temperature changes. The utility model provides a filling device weighs and filling system weighs based on thing networking, viscosity based on different temperature discernment lubricating oil simultaneously through the filling volume of real-time weighing monitoring lubricating oil to the filling to different viscosity sets up valve time of closing in advance, thereby realizes high-efficient, the accurate filling of lubricating oil.
Example 1:
the embodiment provides a filling device weighs, and it can realize lubricating oil's high efficiency, accurate filling under the different temperatures.
As shown in fig. 1, the weighing and filling device includes a weighing module 1, a temperature obtaining module 2, a storage module 3, a processing module 4 and an execution module 5, wherein:
the weighing module 1 is used for weighing an oil drum filled with lubricating oil for filling an object to be filled;
the temperature acquisition module 2 is used for acquiring the current temperature of the selected lubricating oil of the object to be filled;
the storage module 3 stores temperature-viscosity corresponding information of at least one lubricating oil;
the processing module 4 is respectively connected with the weighing module 1, the temperature acquisition module 2, the storage module 3 and the execution module 5, and is used for matching corresponding viscosity according to the current temperature of the selected lubricating oil and starting the execution module 5 according to the difference between the lightening amount of the oil drum and the preset filling amount of the object to be filled;
and the execution module 5 is used for performing lubricating oil filling on the object to be filled according to the starting command output by the processing module 4.
In order to improve the filling efficiency and reduce the feedback of filling data and weighing data return in the lubricating oil filling process, the storage module 3 further stores viscosity-feedback period corresponding information, the processing module 4 is further used for matching the corresponding feedback period according to the viscosity obtained by matching the current temperature of the selected lubricating oil, and the weighing module 1 returns the weight of the oil drum to the processing module 4 at intervals of the feedback period. The feedback period, i.e. the period of the lubricating oil filling operation, represents the time for which the execution module 5 controls the lubricating oil filling operation at a time.
Preferably, the weighing and filling device further includes a Real-Time module 6 connected to the processing module 4, and the Real-Time module 6 is a Real-Time timer 61 (RTC) for providing a non-interrupted Time service and a feedback period measurement of the weighing and filling device.
In the weighing and filling device of the present embodiment, the temperature acquisition module 2 includes at least one temperature sensor 21 disposed in the oil drum. The length of the feedback period setting is related to the current temperature of the lubricating oil obtained by the temperature sensor 21. The weighing and filling device can realize accurate control filling, detect the weight change of the weighing module 1 in each action period for filling lubricating oil, and when the accumulated lightening quantity of the oil drum does not reach the preset filling quantity, the execution module 5 continuously starts the next filling action period to keep the valve open to continue filling; when the accumulated lightening amount of the oil drum reaches the preset filling amount, the execution module 5 stops filling action, and lubricating oil filling is stopped by closing the valve.
The execution module 5 comprises a valve relay 51, the valve relay 51 is used for controlling a power source (such as an air pump) to open or close a valve for filling lubricating oil from an oil drum to an object to be filled through an oil filling pipe, and the processing module 4 outputs a starting command to the execution module 5 at intervals of a feedback cycle, wherein the starting command comprises a valve opening command and a valve closing command. The feedback period is the time that the control valve relay 51 controls the valve to open for one time of filling the lubricating oil.
In the weigh-in apparatus, the valve relay 51 may be periodically turned off. The processing module 4 outputs a starting command to the execution module 5 in a feedback period, and at the end time of each feedback period, the valve is in a closed state, so that the problem of reading jump of the weighing module 1 caused by shaking of the power source in the working process can be effectively avoided. The weighing module 1 obtains static accurate data, and can ensure that the oil drum weighing data obtained by the processing module 4 at each time is determined, thereby ensuring the filling metering precision.
Because the viscosity of the lubricating oil changes greatly under different temperatures and the flow rates of the lubricating oil are not the same even under the same power source power under different viscosities, in order to accurately control the filling amount, a smaller interval can be set as a feedback period when the temperature is higher (i.e. the viscosity of the lubricating oil is smaller) so as to obtain higher filling accuracy; when the temperature is low (namely the viscosity of the lubricating oil is high), a larger interval can be set as a feedback period so as to reduce the filling interruption possibly caused by frequent starting and stopping of the valve by the intermediate monitoring data, thereby improving the filling efficiency. If the preset filling amount is reached, a stop instruction is sent to the valve relay 51, and the valve is closed to cut off the lubricating oil filling; and if the accumulated lightening quantity of the oil drum does not reach the preset filling quantity, the lubricating oil filling is restarted.
Accordingly, in order to improve the data processing efficiency and reduce the number of valve closing operations, the command to close the valve may be executed only when the filling is close to the end sound. Preferably, when the difference between the lightening amount of the oil drum and the preset filling amount of the object to be filled is not greater than a set threshold, the processing module 4 outputs a starting command for closing the valve to the execution module 5, and the set threshold comprises 0.1% -1% of the preset filling amount. Along with power supply, oil filler pipe pour into the object of waiting to annotate with lubricating oil, the weight of oil drum is lightening gradually, reaches the time of setting for the threshold value at lubricating oil filling, promptly to the filling of different viscosities sets up the moment of closing valve time in advance. The set threshold value can be obtained by performing difference operation on the weight reduction amount and the preset filling amount of the oil drum through a comparator, and detailed description is omitted here.

Preferably, a first isolator 52 is provided between the processing module 4 and the valve relay 51 for electrical isolation. The valve relay 51 is connected to a power source (i.e., a power control device, not shown in fig. 2) for filling lubricating oil, and the opening or closing of the valve for filling lubricating oil is realized by controlling the opening and closing of the valve relay 51, so as to implement the execution and stop of the action for filling lubricating oil. The power source can be a hydraulic pump connected with the oil drum through a flexible hose, and can also be an air pump in semi-rigid connection, and the power source and the valve relay 51 in the embodiment adopt the existing general power equipment and control mode, and are not limited here.

In the signal conditioning module 7, the amplifier 71 firstly amplifies the voltage signal of the pressure sensor 11, and amplifies the signal to the range of the analog-to-digital converter 73; then the filter 72 filters the signal to filter out the noise introduced by various mechanical jitters; then, the analog-to-digital converter 73 (e.g., a 16-bit AD converter) converts the analog signal into a digital signal to obtain the current oil drum weight (gross weight). It is easy to understand that the difference between the current oil drum weight (gross weight) and the oil drum weight (gross weight) at the beginning of filling is the filled amount of the lubricating oil.
Preferably, the weighing data of the oil drum is acquired after a certain time delay (for example, 3s), then analog weighing data signals are converted into digital signals through analog-to-digital (AD) conversion, and whether the accumulated reducing amount of the oil drum reaches the preset filling amount is judged.

By arranging the emergency stop button 20, an operator can manually intervene to cut off the filling process when the filling is abnormal or equipment faults occur, so that loss or danger is avoided.
Preferably, a second isolator 100 and a third isolator 110 are also respectively arranged between the processing module 4 and the status indicator lamp 10 and the emergency stop button 20 for electrical isolation and safety of the internal circuit of the processing module 4.
