[0050] The embodiment of the present invention provides a handheld measurement method for material inventory, which is applied to a handheld measuring instrument. Figure 3 , Figure 3 It is a schematic flow chart of a first embodiment of a handheld material inventory measurement method of the present invention.

[0051] In this embodiment, the handheld measurement method of material inventory includes:

[0052] Step S10, when receiving a measurement instruction, executing and controlling the laser distance measurement module to measure the empty height data of the target container, wherein the empty height data is the distance data between the height of the material in the target container and the handheld measuring instrument;

[0053] In this embodiment, the handheld measuring instrument here can be handheld and controlled by the material management personnel. Optionally, install a suitable battery and press the power button for 3 seconds to light up the display screen of the handheld measuring instrument and enter the power-on state. The user confirms the measurement instruction by pressing the measurement button. When the handheld measuring instrument receives the measurement instruction, it controls the laser ranging module to measure the emission of a short pulse of laser and receives the laser pulse reflected by the object. By measuring the time difference between the emission of the laser pulse and the reflection back, the height data is determined.

[0054] Step S20, determining the material inventory data of the target container according to the empty height data;

[0055] The first data is subtracted from the empty height data, and the material height of the material in the current target container is calculated based on the first data and the maximum storage material height of the target container, and the material inventory data is determined based on the material height.

[0056] Step S30: sending the material inventory data to a server so that the server stores the material inventory data.

[0057] In this embodiment, optionally, the material inventory data is directly sent to the server, preferably, the material inventory data is displayed on the screen, and the user determines whether to send the material inventory data to the server. Optionally, when the network cannot be connected, the material inventory data can also be directly stored on the TF card, and after the network is successfully reconnected, the material inventory data is sent to the server.

[0058] In this embodiment, a handheld measurement method for material inventory applied to a handheld measuring instrument is proposed. When a measurement instruction is received, the laser ranging module is controlled to measure the empty height data of the target container, and the material inventory data of the target container is determined according to the empty height data, thereby realizing accurate handheld measurement of material inventory data, and sending the material inventory data to a server. This method does not require the handheld measuring instrument to be set in the container environment for a long time, reduces the resources consumed by maintenance, and does not require the pre-laying of wiring harnesses, thereby realizing the detection of material inventory while reducing the resources required for measurement.

[0059] Further, based on the first embodiment, a second embodiment of the handheld material inventory measurement method of the present invention is proposed. In this embodiment, referring to Figure 4 The handheld measuring instrument is provided with a wireless radio frequency identification module. When receiving a measurement instruction, before executing the step of controlling the laser ranging module to measure the empty height data of the target container, it also includes:

[0060] Step S01, when receiving an identification instruction, controlling the wireless radio frequency identification module to send an activation signal to the electronic tag, so that the electronic tag returns the identification information of the electronic tag;

[0061] It should be noted that, in this embodiment, the measuring bracket is arranged on the top of the target container, and the measuring bracket is provided with an electronic tag matching the wireless radio frequency identification module, i.e., an identification chip, for example, an NFC module identifies a chip that complies with the ISO14443A / MIFARE standard. Of course, in some embodiments, the electronic tag may be arranged at other positions of the target container.

[0062] Step S02, receiving the identification information returned by the electronic tag, and determining the container identification of the target container according to the identification information;

[0063] In this embodiment, the electronic tag is specifically used to distinguish different containers.

[0064] Step S03: Associating the container identifier with the measurement instruction.

[0065] In this embodiment, after the container identifier is determined, it is determined that the measurement instruction obtained within the preset time is to measure the container corresponding to the container identifier. The preset time here can be 30 seconds. When the time difference between the received instruction and the time of receiving the identification instruction is greater than the preset time, the screen prompts that the wireless radio frequency identification module needs to be controlled again to send an activation signal to the electronic tag so that the electronic tag returns the identification information of the electronic tag, and the steps S02 and S03 are executed. In other embodiments, the user needs to click the confirmation button in the process of associating the container identifier with the measurement instruction, and there is no need to set a preset time.

[0066] In this embodiment, the measuring bracket is set on the top of the target container, and the wireless radio frequency identification module is controlled to send an activation signal to the electronic tag, so that the electronic tag returns the identification information of the electronic tag and sends the material inventory data to the server, thereby improving the accuracy of determining the material inventory data in the measured container.

[0067] Furthermore, while sending the material inventory data to the server, the step also includes:

[0068] determining a container identifier corresponding to the material inventory data according to the measurement instruction;

[0069] The container identifier is sent to a server.

[0070] In this embodiment, the material inventory data is not sent to the server separately, but the container identifier and the material inventory data are sent to the server at the same time. Of course, in other embodiments, by marking the target container to which the material inventory data belongs, only the material inventory data can be sent to the server.

[0071] In this embodiment, the container identifier corresponding to the material inventory data is determined through the measurement instruction, and the container identifier is sent to the server so that the accuracy of the sent data can be accurately determined.

[0072] In addition, it should be noted that in this embodiment, after executing the step of controlling the laser ranging module to measure the empty height data of the target container, the following steps are further included:

[0073] Get the current handheld measurement mode;

[0074] When the handheld measurement mode is the first mode, the step of determining the material inventory data of the target container according to the empty height data is performed;

[0075] When the handheld measurement mode is the second mode, the container identification and the empty height data are sent to the server, so that the server determines the material inventory data of the target container according to the empty height data, and stores the material inventory data;

[0076] The first mode and the second mode are two different handheld measurement modes.

[0077] In this embodiment, the first mode is to calculate the material inventory data on the handheld measuring instrument; and the second mode is to calculate the material inventory data on the server; specifically, the first mode and the second mode here can be set by the user independently. Of course, in some embodiments, when it is detected that the power supply is too low, the first mode is switched to the second mode, and the power of the handheld measuring instrument is saved by reducing the running process of the handheld measuring instrument. When the server receives the container identification and the empty height data, it recognizes that the handheld measuring instrument is in the second mode, and determines the material inventory data of the target container according to the empty height data.

[0078] Further, based on any of the above embodiments, a third embodiment of the handheld material inventory measurement method of the present invention is proposed. In this embodiment, the handheld measuring instrument is provided with a display screen, and after the step of determining the material inventory data of the target container according to the empty height data, it also includes:

[0079] Controlling the display screen to display the material inventory data and receiving operation instructions;

[0080] When the operation instruction is a save instruction, the step of sending the material inventory data to the server is executed.

[0081] In this embodiment, the display screen is controlled to display the material inventory data so that the user can see the measurement result. The user inputs an operation instruction according to the displayed measurement result, such as a confirmation instruction, a save instruction, and a delete instruction. In other embodiments, a sound playing device may also be provided. After the step of determining the material inventory data of the target container according to the empty height data, the method further includes: controlling the sound playing device to play the material inventory data and receiving an operation instruction; when the operation instruction is a save instruction, executing the step of sending the material inventory data to the server.

[0082] In this embodiment, by displaying the acquired material storage data, the management personnel can determine whether it is necessary to record. After determining that it is necessary to record, the step of sending the material inventory data to the server is executed, thereby improving the accuracy of the acquired material inventory data compared to setting up a fixed measuring device.

[0083] Further, based on any of the above embodiments, a fourth embodiment of the handheld material inventory measurement method of the present invention is proposed. In this embodiment, a measurement bracket is provided on the top of the target container. Figure 5 ,exist Figure 5 Figure (a) is a measuring bracket, Figure (b) is a handheld measuring instrument, and Figure (c) is a combination of the measuring bracket and the handheld measuring instrument. The measuring bracket is used to fix the handheld measuring instrument. The handheld measuring instrument is provided with a display screen. After receiving the measurement instruction, it also includes:

[0084] Determining whether a measurement condition is met according to current state information of the handheld measuring instrument, the measurement condition being that the handheld measuring instrument has been fixed to the measuring bracket;

[0085] When the current state information does not meet the measurement conditions, controlling the display screen to measure prompt information;

[0086] When the current state information reaches the measurement condition, the step of controlling the laser ranging module to measure the empty height data of the target container is executed.

[0087] In this embodiment, a pressure sensor can be set on the surface of the handheld measuring instrument. Specifically, it is set at the position where the surface of the handheld measuring instrument contacts the measuring bracket when the handheld measuring instrument is fixed to the measuring bracket. When the pressure value collected by the pressure sensor is a preset pressure, it is determined that the handheld measuring instrument has been fixed to the measuring bracket.

[0088] Further in other embodiments, the handheld measuring instrument further includes a gyroscope for determining whether the measuring direction of the laser ranging module is the same as the gravity direction before the handheld measuring instrument is measured. Specifically, the first angle of the laser ranging module is determined according to the gyroscope and the first angle is subtracted from the gravity angle of the gravity direction to obtain an error angle. When the error angle is less than or equal to the preset angle, it is determined that the current state information meets the measurement conditions, and the step of controlling the laser ranging module to measure the empty height data of the target container is executed. Further, in this embodiment, the error angle corresponding to each container can also be recorded to obtain multiple error angles, each error angle corresponds to a container, and it is determined whether the handheld measuring instrument is abnormal and whether each container is abnormal according to the statistical situation of the multiple error angles. Specifically, the average value and variance of multiple error angles are calculated. When the average value is greater than or equal to the preset average value, and the variance is less than the preset variance, it is determined that the handheld measuring instrument is abnormal. When the average value is less than the preset average value, and the variance is greater than or equal to the preset variance, it is determined that one or more abnormalities exist in the multiple containers. And the abnormal container is further determined based on the multiple error angles. By inspecting the measuring bracket, it is further determined whether the abnormality is on the container or the measuring bracket. Compared with the technical solution of fixed installation on the top of the container, the detection system can be effectively calibrated by comparing the error angles collected on different containers. Specifically, since this inspection method is executed after receiving the measurement instruction, it can be completed before each measurement, and this verification can calibrate the handheld measuring instrument, the measuring bracket and the container. The resources consumed by this method of inspection are lower than the resources consumed by the technical solution of fixed installation on the top of the container during the inspection process, and the frequency of verification can be higher.

[0089] In addition, the present application also proposes a fifth embodiment of a handheld material inventory measurement method applied to a server, the handheld material inventory measurement method comprising the following steps:

[0090] Receiving material inventory data sent by the handheld measuring instrument, and storing the material inventory data;
