Description

Technical Field

[0001] The invention relates to the technical field of mechanical equipment maintenance, and in particular to an anti-missing tool box and a tool counting method. Background Art

[0002] Generally, a large number of tools are used in the manufacturing, maintenance, and troubleshooting of various devices and equipment. During the maintenance process, manual counting and photo retention are generally used to assist in the management of tools during the operation to prevent the tools used in the operation from being left out at the operation site, thereby avoiding possible safety hazards.

[0003] Existing smart toolboxes can perform automatic inventory through RFID (Radio Frequency Identification) technology, but there are still some defects in actual applications. For example, currently the system is triggered when the toolbox is closed to determine whether a tool is missing. However, the toolbox also needs to be closed when taking out tools for operation on site. At the same time, the toolbox may be moved from one place to another without closing the toolbox, and it cannot effectively ensure that the tools left on site are found. For example, existing toolboxes all have a power switch, but if the operator forgets to turn on the power, the anti-missing function of the entire box will become invalid. For example, if multiple people work on site at the same time and the tools are misplaced, it will also lead to misjudgment of the toolbox. Summary of the invention

[0004] In view of the above-mentioned shortcomings, the main purpose of the present invention is to provide an anti-missing tool box and a tool inventory method, aiming to solve the technical problem of ensuring that tools are not missed at the work site during operation, thereby avoiding the potential safety hazards caused thereby;

[0005] Another object of the present invention is to provide an anti-missing tool box and a tool inventory method to reduce the tedious process of manual inventory by operators and avoid human factors affecting the inventory results.

[0006] To achieve the above object, the present invention provides an anti-missing tool box, the anti-missing tool box comprising:

[0012] The control module is arranged in the box and is connected with the RFID reading and writing module, the motion sensing module, the alarm module and the Hall switch.

[0013] Optionally, the motion sensing module includes one of a tilt sensor, a non-contact displacement sensor and a non-contact length measurement sensor.

[0014] Optionally, when the handle of the box is arranged on the side of the box, the motion sensing module uses the tilt sensor;

[0015] When the handle of the box is arranged on the top of the box, the motion sensing module selects the non-contact displacement sensor or the non-contact length measurement sensor.

[0016] Optionally, the power supply state switching includes:

[0017] When the Hall switch senses that the box is opened, the power supply state of the box is triggered to automatically turn on;

[0018] When the Hall switch senses that the box is closed, it triggers the delayed closing of the power supply state of the box and triggers the RFID reading and writing module to work.

[0019] Optionally, a plurality of conductive films are provided on the inner side wall of the box body, and the conductive films are used to reflect the signal sent by the RFID reading and writing module.

[0020] Optionally, the box body includes a box cover, a box base and a partition, the box cover and the box base are hinged, the partition is arranged in the box base and divides the box base into an upper cavity and a lower cavity, the upper cavity is used to accommodate the tool, and the lower cavity is used to accommodate the control module, the RFID reading and writing module, the motion sensing module and the alarm module.

[0021] Optionally, a plurality of layer plates are disposed in the upper cavity, and each layer plate is provided with a tool slot for storing the tool.

[0022] Optionally, the anti-missing toolbox also includes a list reset key, a battery module and a display screen, wherein the list reset key is arranged on the outer surface of the box body, and the list reset key, the battery module and the display screen are all connected to the control module.

[0023] A tool inventory method comprises the following steps:

[0024] Using any of the above-mentioned anti-missing tool boxes to identify and save the initial information of all tools in the box;

[0025] When the operation is completed and the box is closed, the Hall switch triggers the power supply state to be delayed and closed, and triggers the RFID reading and writing module to start; or, when the box is lifted, the motion sensing module triggers the RFID reading and writing module to start;

[0026] The RFID reading and writing module identifies the current information of the tools in the box;

[0027] The control module compares the current information with the initial information;

[0046] In addition, the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0047] Please refer to Figure 1-2 This embodiment provides an anti-missing toolbox, and the anti-missing toolbox 100 includes:

[0048] Box 1 is used to store tools with electronic tags (not shown). The specific shape of box 1 can be a regular shape such as a rectangle, and the electronic tag information on each tool is unique to prevent misjudgment of tool information.

[0049] RFID reading and writing module 2, used to identify the electronic tag set on each tool in the box 1 to obtain the information of each tool;

[0050] The motion sensing module 3 is used to sense whether the box 1 is actually lifted. If it is actually lifted, it will trigger the RFID reading and writing module 2 to start working;

[0051] An alarm module is used to send out an alarm signal to remind whether a tool is left behind. The specific form may be a buzzer or a photoelectric alarm, etc.;

[0052] The Hall switch 4 is arranged at the opening of the box 1, and is used to sense the opening and closing state of the box 1, so as to trigger the switching of the power supply state of the box 1. Specifically, when the Hall switch 4 senses that the box 1 is opened, the power supply state of the box 1 is automatically turned on, and the power supply state between each module is maintained; when the Hall switch 4 senses that the box 1 is closed, the power supply state of the box 1 is delayed and turned off, and the RFID reading and writing module 2 can be triggered to work.

[0053] The control module 5 is arranged in the box body 1 , serves as the control center of the box body 1 , and is connected with the RFID reading and writing module 2 , the motion sensing module 3 , the alarm module and the Hall switch 4 .

[0054] In the present invention, the motion sensing module 3 is designed to sense the movement of the box 1 or the Hall switch 4 senses the closing of the box 1, which can trigger the RFID reading and writing module 2 to work, that is: when the box 1 is opened for operation, the box 1 is in a power supply state. If the box 1 is moved from one place to another work place without closing the box 1, the motion sensing module 3 senses that the box 1 is lifted, which will trigger the RFID reading and writing module 2 to work, and start the inventory program to determine whether there are any missing tools; when the operation is completed, when the operator closes the box 1, the Hall switch 4 will trigger the power supply state to be delayed and closed, and the probability of reading the electronic tag is further increased through the time setting, which will also trigger the RFID reading and writing module 2 to work, and start the inventory program to determine whether there are any missing tools; or within the delayed time period, the motion sensing module 3 senses that the box is lifted, which will also trigger the RFID reading and writing module 2 to work, and start the inventory program to determine whether there are any missing tools.

[0055] In addition, since the electronic tag information on each tool is unique, if multiple people are working on site at the same time and the tool is placed in the wrong box, the current information of the tool will be inconsistent with the initial information, and the box will also send out an alarm signal. The entire process no longer has the problem of human factors affecting the omission of tools, which solves the problem that the original technology has not completely avoided the judgment of the results by human factors, such as the operator forgetting to turn on the power of box 1, the operator taking box 1 away without closing it, and taking the tool to work without closing box 1, etc., which affects the judgment of the anti-omission result.

[0056] In this embodiment, the motion sensing module 3 includes one of an inclination sensor (not shown), a non-contact displacement sensor (not shown) and a non-contact length measuring sensor (not shown). The inclination sensor, the non-contact displacement sensor and the non-contact length measuring sensor are all prior art.

[0057] In this embodiment, the handle of the box 1 is arranged above the box 1, and the motion sensing module 3 uses a non-contact displacement sensor or a non-contact length measuring sensor. Because when the box 1 is lifted, it will be displaced from the ground, and the non-contact displacement sensor or the non-contact length measuring sensor is used to sense the change in the distance between the box 1 and the ground. When it exceeds a certain range, the RFID reading and writing module 2 can be triggered to start the inventory procedure.

[0058] In another embodiment, the handle of the box 1 is set on the side of the box 1, and the motion sensing module 3 uses an inclination sensor. Because when the box 1 is lifted, the box 1 will flip approximately 90 degrees, and the inclination sensor can sense the change in the angle of the box 1. When it exceeds a certain angle range, the RFID reading and writing module 2 can be triggered to start the inventory procedure.

[0059] In this embodiment, since tools are generally metal parts, when multiple tools are stacked, it will cause great interference to the signal reception of the electronic tag attached to the tools, thereby affecting the recognition rate. The box body 1 is generally made of plastic material. By arranging a plurality of conductive films (not shown) on the inner wall of the box body 1, the conductive films are used to reflect the signal sent by the RFID reader / writer module 2, so that the signal sent by the RFID reader / writer module can be continuously reflected in the box body 1, thereby improving the connection probability between the electronic tag and the signal source of the RFID reader / writer module 2, thereby improving the recognition rate of the tool.

[0060] In this embodiment, the box body 1 includes a box cover 11, a box seat 12 and a partition 13. The box cover 11 and the box seat 12 are hinged. The partition 13 is arranged in the box seat 12 and divides the box seat 12 into an upper cavity and a lower cavity. The space of the upper cavity is larger than the space of the lower cavity. The upper cavity is used to accommodate tools, and the lower cavity is used to accommodate equipment such as a control module 5, an RFID reading and writing module 2, a motion sensing module 3 and an alarm module.

[0061] In this embodiment, a plurality of layer plates (not shown) are disposed in the upper cavity, and each layer plate is provided with a tool slot (not shown) for storing tools.

[0062] In this embodiment, the anti-missing toolbox also includes a list reset key 6, a battery module 7 and a display screen 8. The list reset key is arranged on the outer surface of the box body, which is convenient for the operator to initialize and save the data list. The display screen 8 is convenient for the operator to intuitively view the corresponding data information, and the list reset key, battery module and display screen 8 are all connected to the control module.

[0064] S1: using the anti-missing tool box described in any one of the above embodiments to identify and save initial information of all tools in the box;

[0065] S2: When the operation is completed and the box is closed, the Hall switch triggers the power supply state to be delayed and closed, and triggers the RFID reading and writing module to start; or, when the box is lifted, the motion sensing module triggers the RFID reading and writing module to start;

[0066] S3: The RFID reading and writing module identifies the current information of the tools in the box;

[0067] S4: The control module compares the current information with the initial information;

[0068] S5: If the current information is inconsistent with the initial information, the box sends out an alarm signal; if the current information is consistent with the initial information, the box does not respond.

[0069] In this embodiment, step S1: using any of the above-mentioned anti-missing tool boxes to identify and save initial information of all tools in the box, includes:

[0070] S11: Open the box, and the Hall switch senses and triggers the power supply state of the box to automatically turn on;

[0071] S12: placing the tool with the electronic tag in the box;

[0072] S13: closing the box, and the Hall switch triggers the power supply state of the box to be closed with a delay;

[0074] S15: The control module obtains the electronic tag data;

[0075] S16: Initialize the list and save the data.

[0076] The advantage provided by the present invention is that the motion sensing module is designed to sense the movement of the box or the Hall switch senses the closing of the box, which can trigger the RFID reading and writing module to work, ensuring that the tools are not left at the work site during operation, and when the box is closed, the power supply state will be delayed to turn off, which can reduce power consumption.
