Description
Technical Field
The application relates to the technical field of weight metering equipment, in particular to an electronic weighing instrument, which is expanded in function and more accurate in weighing.
Background
Weighing instruments, otherwise known as scales, are tools frequently used in daily production and life of people. Along with the development of science and technology, traditional mechanical weighing appearance by the lever, support connecting piece and balance weight are constituteed is replaced by electronic weighing appearance gradually, and these electronic weighing appearance mainly include weighing sensor, mainboard and display, will wait to weigh the article and put on weighing sensor during the use, and the display can show the weight of article, convenient to use. Manufacturers of electronic weighing machines have generally focused on the development of such devices to obtain more accurate weight values for the sensors through the development of sensor technology. However, in some cases, the user may obtain an incorrect weight value no matter how accurate the sensor obtains the value.
For example, in real production life, when a user weighs an object having a plurality of support points, there may be a case where individual support points are not on the weighing table but on the ground or on a table other than the weighing instrument. In this case, even if the accuracy of the sensor is higher, the measured stable accurate value is not the true weight value of the object because the other supporting points share the weight of the object, which is not taken into account by the weighing apparatus. This situation often occurs when animals with four legs, such as sheep, pigs, cattle, etc., are weighed in animal husbandry, or objects with multiple support points, such as tables, chairs, automobiles, etc., are weighed, resulting in that the true weight value of the object to be weighed cannot be obtained.
In addition, if a plurality of objects are weighed simultaneously, a situation of weighing more or less due to artificial counting errors sometimes occurs, for example, a user wants to weigh five objects, but only four or six objects are on the electronic weighing apparatus due to errors, if the objects are not found in time, the displayed weight value is mistakenly regarded as the real weight value of a plurality of objects to be measured, and the situation is also easy to occur when the number of the objects to be weighed at one time is large.
The above situation that the actual weight value of the object cannot be obtained is not caused by insufficient accuracy of the sensor, but the situation brings much invariance to the use of the electronic weighing instrument in the above situation. Therefore, in view of the above technical problems, there is a need in the market for a weighing apparatus or a weighing method that enables a user to conveniently obtain a true weight value of an object to be measured even in weighing measurement of a multi-point supported object or a plurality of objects.

In view of this, the present application expands the functions of the existing electronic weighing apparatus, and when a user weighs and measures a multi-point supported object or a plurality of objects, the present application can help to determine whether all supporting points of the object are within a weighing range or help to count, so that the probability of errors generated when weighing such objects can be effectively reduced. The application particularly provides a weighing method and an electronic weighing instrument realized according to the method.
The multi-contact weighing method comprises the following steps:
the estimated contact number is sent to a controller and stored;
the actual number of contacts is sent to a controller and stored;

the controller waits for user feedback;
or the user changes the preset number of the expected contact points again and then instructs the weighing instrument to continue weighing to represent the feedback in the step 5;
and 8, the controller calls the latest weight data as the effective weight of the object to be measured and outputs the effective weight to the user.
Further, in the step 1, the expected number of contacts is preset through an input keyboard or a touch device; or the expected number of the contacts is set through Ethernet, serial ports, WiFi, Bluetooth or 3G/4G communication modes.
Further, in the step 5, a buzzer or a light flashing mode is used for prompting that the expected number of the contacts is inconsistent with the actual number of the contacts.
Further, in the step 8, the effective weight is displayed and output to a user through an external or internal display device; or outputting the effective weight to a user through Ethernet, serial port, WiFi, Bluetooth and 3G/4G communication modes.
Preferably, in the step 2, a label of the object to be detected is obtained, and the label is sent to a controller and stored; in connection with this, in the step 3, the method further includes associating both the actual number of contacts and the weight data with the tag; meanwhile, in the step 8, the outputting to the user includes outputting the tag and the effective weight corresponding to the tag at the same time.
The expected number of contacts may also be selected in the following manner: a value, a plurality of values, or a range of values.
For the convenience of the user, the step 5 may be replaced by: prompting a user that the estimated number of contacts is inconsistent with the actual number of contacts; in accordance with this, the step 6 is replaced by: and automatically acquiring the number and weight data of the actual contact points of the object to be measured on the weighing instrument after a preset time interval.
The invention also provides a weighing instrument for weighing according to the weighing method, which comprises a weight sensor, a weighing platform, a main board, a display module and a weighing frame, and is characterized in that: the device also comprises a contact sensor, an input module and an alarm prompt module; the weight data is obtained through the weight sensor, the actual contact number is obtained through the contact sensor, the expected contact number is set through the input module, and the alarm prompting module prompts that the expected contact number is inconsistent with the actual contact number.
Preferably, the weighing apparatus further comprises a communication module for setting said expected number of contacts and/or outputting the effective weight to a user.
Further, the contact sensor is arranged on the upper side of the weighing platform, and the weight sensor is arranged on the lower side of the weighing platform.

Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be described in detail and completely with reference to the following specific embodiments of the present application and the accompanying drawings. It should be apparent that the described embodiments are only some of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The biggest difference from the traditional electronic weighing instrument is that the electronic weighing instrument further comprises a contact sensor. The touch sensor may be a common resistive, capacitive, acoustic, infrared, optical touch screen, or mechanical touch sensor (single-point or multi-point), or may be other sensors capable of detecting the touch point of an object.
The resistance-type touch screen is a pressure-sensitive sensor, is not afraid of dust and steam, can adapt to various adverse environments, is also applicable to the touch that any object produced simultaneously, and stability can be better. The sensor can convert the physical position of the touch points (X, Y) in the rectangular area into voltage representing an X coordinate and a Y coordinate, and the controller acquires the specific number and the position of the touch points according to the read voltage value.
The capacitive touch screen is provided with long and narrow electrodes on four sides of the touch screen, and a low-voltage alternating current electric field is formed in a conductor. When the screen is touched, a coupling capacitor is formed between the living contact and the conductor layer, the current emitted by the four-side electrodes flows to the contact, the intensity of the current is inversely proportional to the distance between the living contact and the electrodes, and the controller can calculate the proportion and the intensity of the current and accurately calculate the position of the touch point.
An acoustic touch screen is comprised of a touch screen, an acoustic generator, a reflector, and an acoustic receiver, wherein the acoustic generator is capable of transmitting a high frequency acoustic wave across the surface of the screen, and when an object touches the screen, the acoustic wave at the touch point is blocked, and the controller determines the coordinate position therefrom.
The infrared type touch screen is implemented in a similar principle to the surface acoustic wave type touch screen except that an infrared transmitting and receiving sensing element is used. The elements form an infrared detection network on the surface of the screen, an object which is touched to operate can change the infrared ray of the contact point position, and then the coordinate position of the contact point is obtained through the change of the infrared signal, and the subsequent control operation is realized.
The optical touch screen is characterized in that an LED lamp is arranged at the top, such as the upper left corner, and light emitted by the LED lamp enters a CCD camera at the upper right corner through the reflection of the peripheral reflection strips. In a similar way, the light emitted by the LED lamp arranged at the upper right corner can also be transmitted into the CCD camera at the left side. The densely packed light forms a network of light lines in the touch area. When a touch point enters the optical line network, an included angle is formed by the emitted light and the received light of the point, and meanwhile, two included angles are formed by the CCD cameras at the two ends, the two light and straight lines formed between the two cameras.
The mechanical touch sensor (single-point or multi-point) is also a pressure-sensitive switch sensor, the state of the switch changes when the mechanical touch sensor contacts an object, and the controller obtains the specific position of the contact by monitoring the state of the switch.
The contact sensors can be arranged on the surface of the electronic weighing instrument, and the mechanical touch sensors (single-point or multi-point) can also be arranged in the electronic weighing instrument. The data output of the touch sensors can be directly transmitted to the controller after necessary level conversion, the controller (such as a single chip microcomputer and an ARM) processes the data (such as ADC conversion sampling or direct reading), and the specific number and the position of the touch points are calculated. Of course, it is also possible to select commercially mature touch screen modules via various communication interfaces such as I2C. The specific number and position of the contacts are directly obtained by the SPI, the serial port, the Ethernet port and the like. Specifically, when the number and the positions of the contacts are calculated, the contact area and the contact range can be considered through algorithm setting, for example, one contact point can be calculated for a plurality of adjacent contact points or a large-range contact area, and thus, even if the support base areas of the object to be measured are different, the number of the contact points of the object to be measured or the number of the object to be measured can be accurately obtained.
Description figure 1 shows a schematic flow diagram of a method for weighing using the electronic weighing apparatus of the present application. As shown in fig. 1, the core step includes the controller comparing the output result of the touch sensor with the stored value set by the user, if the output result of the touch sensor meets the condition preset by the user, calling the weight value of the weight sensor and outputting, for example, displaying the weight value on the display of the electronic weighing apparatus. The specific weighing method comprises the following steps:
step 1: the user sets the expected number of contacts of the object to be measured when the object to be measured is placed on the weighing instrument or the number of the objects to be measured by inputting a keyboard or communication modes such as Ethernet, serial ports, WiFi, 3G/4G and the like; the user-set expected number of contacts or objects is sent to the controller and stored.
Step 2: and placing the object to be measured on a weighing instrument.
And step 3: the controller acquires actual contact data or object quantity data of the object to be measured on the weighing instrument from the contact sensor, and the data is processed, analyzed or calculated to obtain the position of the object and the actual contact number or quantity and is stored; the weight sensor weighs an object on the weighing instrument and sends weight data to the controller.
And 4, step 4: the controller calls the predicted number of the contacts or the predicted number of the objects set by the user and the actual number of the contacts or the actual number of the objects detected by the contact sensor, and compares the predicted number of the contacts or the predicted number of the objects; if the estimated number of contacts or the estimated number of objects is consistent with the actual number of contacts or the actual number of objects, performing step 8; if the predicted number of contacts or the predicted number of objects does not coincide with the actual number of contacts or the actual number of objects, step 5 is performed.
And 5: prompting a user that the predicted contact number is inconsistent with the actual contact number, or prompting that the predicted object number is inconsistent with the actual object number; preferably, the actual number of contacts or the actual number of objects may also be displayed to the user; the controller waits for user feedback;
step 6: the user adjusts the position, the posture or the quantity of the object to be measured on the weighing instrument, and the weighing instrument is instructed to continue weighing after the adjustment is finished so as to represent the feedback in the step 5; or the user changes the preset number of the contacts or the preset number of the objects when the objects to be measured are placed on the weighing instrument again, and then the weighing instrument is instructed to continue weighing to represent the feedback in the step 5;
and 7: the controller returns to the step 3 after receiving the feedback;
and 8: the controller calls weight data transmitted by the last weight sensor as the effective weight of the weighed object, displays the weight data to a user through an external or internal display screen and outputs the weight data, and also transmits the weight data to a computer through a network for processing through communication modes such as Ethernet, serial ports, WiFi, 3G/4G and the like.
In the above weighing method, the controller acquires the number or quantity of contacts of the object to be measured contacting the weighing apparatus through the contact sensor and acquires the effective weight of the object to be measured, and the two sets of acquired effective values are regarded as a pair of values, when the number or quantity of contacts in the pair of values meets the condition of the preset number or quantity of contacts, the weighing is regarded as effective, the controller outputs the effective weight value in the pair of values, otherwise, the weighing is regarded as ineffective, and at this time, preferably, the effective weight value in the pair of values is discarded, or the effective weight value in the pair of values is identified as an ineffective value.
Further preferably, in step 3, after the controller detects that the expected number of contact points does not match the actual number of contact points, or after the controller detects that the expected number of objects does not match the actual number of objects, the contact sensor and the weight sensor repeatedly detect the number of object contact points and the weight of the object on the weighing instrument according to a preset time interval, until the detected actual number of contact points or the detected actual number of objects matches the preset expected number of contact points or the expected number of objects, the controller automatically retrieves the weight data sent last time and outputs the weight data to the user. Therefore, the user does not need to manually feed back to the electronic weighing instrument to enable the electronic weighing instrument to continue to detect, and the electronic weighing instrument is more convenient to use.
The electronic weighing instrument for realizing the weighing method is shown in the attached figure 2 of the specification and comprises a contact sensor 1, a weighing platform 2, a weight sensor 3, a mainboard 4, a communication module 5, a display module 6, an input module 7, an alarm prompt module 8 and a scale frame 9. The above components are connected according to electrical characteristics and structural features. The core components are two sensors, namely a contact sensor 1 and a weight sensor 3. The outputs of the two sensors are connected with a controller of the mainboard 4, such as a single chip microcomputer, an ARM and the like, through a peripheral circuit, so that the controller acquires corresponding data. The peripheral circuit includes, for example, a level conversion circuit, a communication interface circuit, an ADC circuit, an external memory chip, and the like.
Specifically, the electronic weighing apparatus includes a scale platform 2 and a scale frame 9. The contact sensor 1 is mounted on top of the weighing platform 2 so as to be closest to the object to be weighed to ensure that accurate contact information is obtained. Preferably, a protective layer is further installed on the surface of the contact sensor 1 to reduce the wear of the contact sensor 1 by the object to be measured. For mechanical touch sensors (single-point or multi-point), it is also possible to mount such sensors inside the electronic weighing scale, for example directly below the weighing platform 2. The weighing platform 2 is mainly used for carrying objects to be weighed. The weight sensor 3 is installed below the weighing platform 2 to acquire weight information of the object to be measured on the weighing platform 2. The weight sensor 3 may be a photoelectric, hydraulic, electromagnetic, capacitive, magnetic pole deformation type, vibration type, gyroscope type, resistance strain type, plate ring type, digital type, or other sensor capable of measuring the weight of the object to be weighed. The scale frame 9 specifically comprises a frame body and scale feet, so that the support of the above components is realized.
Preferably, a controller-mounted main board 4 is installed below the weight sensor 3. The communication modules 5 such as Ethernet, serial port, WiFi, 3G/4G and the like can also be integrated on the mainboard 4. The input module 7 and the display module 6 can be arranged on one side of the scale frame 9, so that the user can set and observe conveniently. The input module 7 includes, for example, a keyboard, a mouse, or other touch devices; the display module 6 is, for example, an external or internal liquid crystal display, a display with a touch function, or other display device; the alarm module 8 may use a buzzer, an LED lamp, or other devices. Further, the alarm prompt module 8 may be disposed near the display module 6 or the input module 7.
In one embodiment, the electronic scale of the present application is used to weigh animals in animal husbandry, such as cattle. The electronic weighing instrument can be matched with a fence suitable for animals to be used together in order to adapt to the application of animal husbandry. The electronic weighing instrument can further have a label identification function so as to identify the RFID label on the animal. Identification information, such as an animal's specific serial number, may be sent to the controller for storage after tag identification. Further, the electronic weighing instrument can also transmit accurately measured weight data and the animal specific serial number to a server through the communication module 5 in a wired or wireless mode so as to be used and monitored by other users.
During specific weighing, a user sets the number of expected contact points on a user interface of the electronic weighing instrument, and for a to-be-measured object which is a cow, the number of the expected contact points is four. After the setting is finished, the cattle is caught up to the electronic weighing apparatus, e.g. via a fence.
At this point, the contact sensor 1 will begin to operate, detect the number of contact points of the animal on the scale, and send to the controller. At the same time, the weight sensor 3 also measures the weight of the animal on the scale and sends the weight data to the controller. Since the cow may not have completely stopped on the scale, when only three legs stand on the scale, the number of actual contact points detected by the contact sensor 1 is three. Through comparison of the controller, the number of the contact points does not meet the preset number of four of the contact points of the user. Therefore, the red light is continuously flashed on the alarm prompt module 8 of the electronic weighing instrument to prompt the user that the expected contact point is not in line with the actual contact point, and the weight data at the moment is inaccurate and further cannot be displayed on the display module 6. So that the user does not assume that the weight of the cow is the real weight value of the cow. The user will look for the reason for the discrepancy and then adjust the posture of the cow until the four legs of the cow stand on the scale, at which point the user can confirm on the user interface that weighing continues. After the above-described feedback by the user, the contact sensor 1 of the weighing apparatus again detects the contact point of the animal on the weighing apparatus, and sends the actual detection number "four" to the controller. The weight sensor 3 will also weigh the animal again and send new weight data to the controller. The controller compares the data sent by the contact sensor with the conditions preset by the user after receiving the data, and confirms that the expected number of the contact points at the moment is consistent with the actual number of the contact points, so that the weight data sent last time is displayed on the display, the original flashing red light is turned off, and the green light is turned on to indicate that the weight of the user at the moment is the real weight of the animal to be detected.
Preferably, after the controller detects that the expected number of the contact points does not match the actual number of the contact points, the contact sensor 1 and the weight sensor 3 repeatedly detect the number of the object contact points and the weight of the object on the weighing instrument according to a preset time interval until the detected actual number of the contact points matches the preset expected number of the contact points, the flashing red light is automatically changed into the green light, and the controller automatically retrieves the weight data sent last time and displays the weight data on the display. Therefore, the user does not need to manually feed back to the weighing instrument to enable the weighing instrument to continue to detect, and the use is more convenient.
In another embodiment, a 10-piece rectangular parallelepiped packing box is weighed using the electronic scale of the present application. The electronic weighing instrument can also have a two-dimensional code scanning function so as to conveniently identify the label on the packing box. Identification information, such as a shipping serial number, may be sent to the controller for storage after tag identification. Further, the electronic weighing instrument can also transmit accurately measured weight data and the shipping serial number to a server through the communication module 5 in a wired or wireless mode so as to be used and monitored by other users.
During specific weighing, a user sets the number of expected contact points on a user interface of the electronic weighing instrument, and for the object to be measured, the number of the expected contact points is ten, which is the same as the number of the packing boxes to be measured. After the setting is finished, the packing boxes are moved onto the weighing instrument one by one, and in the moving process, the delivery serial numbers of the packing boxes can be recorded by utilizing the two-dimensional code scanning function.
The contact sensor 1 can automatically start working, detect the number of contact points of the packing box on the weighing instrument and send the number to the controller. Meanwhile, the weight sensor 3 and the contact sensor 1 work synchronously, measure the weight of the packing box on the weighing instrument and send weight data to the controller. For some goods, there is a case where the number is easily counted by man, and after nine packing boxes are conveyed, the user mistakenly regards that ten packing boxes have been conveyed onto the weighing apparatus, so the actual number of contact points detected by the contact sensor 1 is nine at this time. Through comparison of the controller, the number of the contact points does not meet the preset number of the contact points of ten by the user. Therefore, there is no weight display on the display of the electronic weighing instrument, and the number of currently detected contact points "nine" is displayed at a specific display position to prompt the user that the expected contact points do not coincide with the actual contact points, at which time the weight data cannot be output due to inaccuracy. So that the user does not acquire the weight of the wrong ten items. The user can easily adjust the number of items to be tested based on the number of contact points on the display. The contact point sensor 1 and the weight sensor 3 repeatedly detect the number of contact points and the weight of the weighing instrument at preset time intervals. Therefore, when the detected actual number of the contact points accords with the preset expected number of the contact points, the controller automatically retrieves the weight data sent last time and displays the weight data on the display, so that the data on the electronic weighing instrument is always the real weight value of the object to be measured.
In addition, although the expected number of contact points set by the user in the above embodiment is a single number, the actual number is not limited thereto. The expected number of contact points X may be any one or more of X1, X2, … …, Xn, where n is any number. Or may be a range of values: the numerical ranges of < X, > X, X-Y, etc., and even different sets of conditions are possible, where X, Y is any number.
The weighing principle of the present application and the corresponding electronic weighing apparatus have been described above. According to the weighing method for multi-contact discrimination, the problem that a user acquires wrong weight due to the fact that supporting points are not arranged on an electronic scale or the number of objects is wrong can be avoided, and the weighing method is wide in application. For example, the weighing machine is used in daily weighing of multi-legged living bodies in animal husbandry, particularly in weighbridges, can accurately weigh the living bodies such as pigs, cows, sheep, chickens, ducks and geese, and prevents weighing errors caused by the fact that part of supporting points are not on a weighing platform when the living bodies are weighed. The weighing device can be used for weighing the pieces, and can effectively prevent weighing errors caused by incorrect quantities. Or the device can be used in other objects to be measured with multi-point contacts to prevent weighing errors caused by incomplete support points on the weighing platform.
It should be noted that the embodiments and features of the embodiments may be combined with each other without conflict.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in any way, and any simple modification, equivalent change and modification made to the above embodiment according to the technical spirit of the present invention are still within the scope of the technical solution of the present invention.
