Description

Technical Field

[0001] The invention relates to a forklift digital technology. Background Art

[0002] The technical background of local digitalization of forklifts is closely related to the changes in social development and economic needs. With the rapid development of social economy, the demand for forklifts in material handling is increasing, and the utilization rate and efficiency requirements of forklifts are getting higher and higher. However, the traditional forklift information management method can no longer meet the needs of the modern logistics industry, especially for the driver's side. Information support is long-term retained in the vehicle's accompanying documents. When the driver has a problem and needs help, he faces the inconvenience of querying the on-board documents or losing them; the data version is outdated, and there are various difficulties in contact due to personnel changes. Therefore, it is necessary to seek new technical means to improve the efficiency and accuracy of forklift management.

[0003] At present, there are also digital technologies applied in the forklift field. For example, the public document with application number 2021114702974 and patent name "A method for starting up by scanning a QR code on a forklift instrument with a mobile terminal" discloses a method and system for starting up by scanning a QR code on a forklift instrument with a mobile terminal. The method includes: generating and displaying a QR code on the forklift instrument based on the forklift information; generating a power-on password list based on the forklift information and user information allowed to start up; the mobile terminal scans the QR code, parses the forklift information, and sends the forklift information and the pre-stored user ID matching the mobile terminal to the cloud server; the cloud server determines whether the user ID matching the mobile terminal allows the forklift corresponding to the forklift ID to be started, and if allowed, the mobile terminal obtains the power-on password generated based on the forklift information and the user ID matching the mobile terminal; the forklift instrument receives the power-on password, and if the power-on password matches one in the power-on password list, a power-on permission instruction is sent to the vehicle controller. The existing technology uses a QR code generated on the forklift instrument that contains the forklift's ID. The mobile terminal scans the QR code and the cloud server determines whether the user ID matching the mobile terminal is allowed to start the forklift. From this, we can conclude that even if the forklift uses a QR code, it is still based on the forklift driver's identity control and the power-on password control.

[0004] To sum up, the current local digital technology of forklifts still cannot solve the contradiction between the growing local driver information perception needs and the light service and weak informatization in the service process compared with other industrial industries of traditional forklift manufacturers. Summary of the invention

[0005] The basic problem to be solved by the present invention is to improve the information support on the driver side so that the driver can solve the problem conveniently and quickly; to solve the problem that the important parameters, fault interpretation and contact methods that the driver cares about are neglected in the prior art, and to improve the level of informatization in the forklift service process to reduce communication costs.

[0006] In order to achieve the above-mentioned purpose, the technical solution adopted by the present invention is: a forklift local digitization system, including a forklift body, a side panel on one side of the forklift body is provided with a hole, a small side door is hinged on the hole, a QR code fixing bracket is provided on the inner side of the small side door, a static QR code containing forklift information is fixed on the QR code fixing bracket, a camera is fixed on the inner side of the side panel, the shooting direction of the camera is toward the static QR code and obtains the static QR code information, the camera is connected via a data cable and outputs the collected signal to a display screen for display, and the display screen is installed in the cab of the forklift body.

[0007] The side door is made of light-transmitting frosted material, and the graphic of the static two-dimensional code is made of fluorescent material.

[0008] A light source is fixed next to the camera to illuminate the static QR code. The camera outputs an image signal to the display screen via a controller. The controller is connected to and outputs a driving signal to the light source. When the camera is working, the controller recognizes the static QR code in real time. If it cannot be recognized, the light source is turned on and the light source is turned off after a set time is delayed after the light source is turned on.

[0009] An electrically controlled installation lock is provided between the side door and the side panel, a warning light is fixed on the side door, and the controller is connected to and outputs a driving signal to the installation lock and the warning light. When the controller cannot recognize the static QR code within a set time, the warning light is started and an alarm is given using the display screen. When the controller recognizes that there is a fault signal of the forklift and the fault signal meets the alarm condition, the installation lock is driven to open the side door.

[0010] The controller acquires the forklift operating condition information in real time, and generates a dynamic QR code from the operating condition information and transmits it to the display screen for display. The dynamic QR code information content includes the forklift's real-time working status, maintenance records, fault status and information, and positioning information.

[0011] The system is provided with a handheld electronic device for identifying static two-dimensional codes and dynamic two-dimensional codes. The handheld electronic device obtains information of the static two-dimensional code and the dynamic two-dimensional code after scanning the two-dimensional code.

[0014] The static QR code information content includes the height of the forklift load when unloading and the corresponding weight carried, the manufacturer's website, and the name, phone number and position information of the manufacturer's contact person.

[0015] The present invention solves the expansion problem of the forklift service end. The information displayed in the dynamic code can be modified and saved, and then synchronized to the customer level in real time. The driver can also fill in the small program provided by the dynamic code to report the forklift fault information, retrieve the meaning of the fault information, and query the forklift maintenance content.

[0023] The following is a further detailed description of the specific implementation methods of the present invention, such as the shape, structure, relative position and connection relationship between the various components involved, the function and working principle of each part, the manufacturing process and operation method, etc., through the description of the embodiments with reference to the accompanying drawings, so as to help those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the present invention.

[0024] The present invention relates to a forklift local end digitalization technology, which uses a digital information bearing medium installed on the forklift to read information using a mobile phone or other devices, and the digital information bearing medium can use a QR-Code code. The technical field and application scope of forklift local end digital information collection are an indispensable part of forklifts in terms of intelligence and digitalization. This technology involves multiple fields, including data entry and collection processing, wireless communication, cloud processing, etc. Through the comprehensive application of these technologies, forklifts can collect and transmit key information in real time, and provide necessary information display for forklift users and managers. In terms of technical field, forklift local end digital information collection mainly relies on complete and necessary preset input information, which can be correctly collected by information collection equipment, and the modification of information can be synchronized and displayed in time. In terms of application scope, forklift local end digitalization technology includes forklift key parameter information, spare parts information, maintenance information, etc.; in addition to providing necessary information display for forklift users and managers, it can also help enterprises achieve optimal configuration of forklift resources and improve utilization efficiency. For example, by collecting and analyzing forklift operation data, companies can better understand the use of forklifts, identify and solve potential problems in a timely manner, and thus ensure the normal operation of forklifts.

[0025] The digital information carrier medium is mainly established locally, which is divided into static and dynamic forms for reading. The dynamic code can be handed over to the applet or website backend in the cloud for personnel to obtain through mobile phones, computers and other terminals. The existing technology of scanning codes in the forklift field still focuses on startup and safe loading, and has long ignored the key parameters of use, fault interpretation and contact methods that drivers care about. Once a vehicle fails, a lot of time and human communication costs are wasted, and research in this area is in a blank period.

[0026] The local digital system of forklifts establishes digital information carriers through the local end, which are divided into two forms: static code and dynamic code for reading. Static codes store and display relevant information of forklifts in text form, including forklift safety warnings, contact information, and important parameters of forklifts. Dynamic codes can be handed over to small programs or website backends in the cloud for personnel to obtain through mobile phones, computers and other terminals. After scanning, they can view product manuals, basic principles, etc., getting rid of the problems of easy loss, inconvenience in carrying, and outdated versions of paper materials in existing technologies.

[0027] Both static two-dimensional codes and dynamic two-dimensional codes are displayed using the display screen 5. Figure 1As shown, a display screen 5 is installed on the side of the forklift overhead guard frame to facilitate observation by the driver. A hole is opened on the side panel of one side of the forklift body, and a small side door 1 is hinged on the hole. The small side door 1 is used to install a QR code fixing bracket 3. The QR code fixing bracket 3 is L-shaped as a whole. A static QR code containing forklift information is fixed on the QR code fixing bracket 3. A camera 4 is fixed on the inner side of the side panel. The shooting direction of the camera 4 is toward the static QR code and obtains the static QR code information. The camera 4 is connected to the controller via a data cable. The controller is the control core of the system. The output end of the controller is connected to the display screen 5, which controls the display screen 5 to display the static QR code collected by the camera 4 and the dynamic QR code displayed according to the current vehicle status.

[0028] like Figure 2 As shown, the side door 1 of the forklift is fixed to the side panel by a hinge, and the side door 1 and the side panel are directly fixed by installing a lock 2. The lock 2 is a mechanized and electrically controlled door lock. When locked, the side door 1 cannot be opened. The door is equipped with a seal to prevent water from entering, ensuring that when the door is closed, even in rainy and snowy weather, the static QR code cannot be damaged. The lock 2 ensures that non-drivers cannot open the door.

[0029] The QR code fixing bracket 3 is welded on the back of the side door 1. When the side door 1 is in the closed state, the camera 4 can be used to scan the code. The power supply of the camera 4 is taken from the DC converter power supply of the forklift itself. When the whole vehicle is powered on, the camera 4 starts to work and capture images. When the whole vehicle is powered off, the camera 4 is also powered off and does not work. The camera 4 transmits the image model to the display screen 5 in a wired form. People can scan the image through mobile terminals such as mobile phones to obtain information. The camera 4 is adapted to the image acquisition in the QR code fixing bracket 3. When the side door 1 is opened to a certain angle, the camera 4 cannot scan the QR code, so that people can intuitively see the abnormality on the display screen 5, thereby solving the fault.

[0030] Therefore, the controller can be used to realize the fault alarm of the forklift, which is particularly suitable for the modification of old forklifts, because the controller can connect to CAN to obtain the forklift fault information and pre-select all fault codes. The fault code for alarm can be customized. For example, if there is a safety hazard and the fault code affects safe driving, an alarm will be sounded, otherwise no alarm will be sounded. There is no need to improve the vehicle controller. The controller is used for simple control linkage. When the controller recognizes that there is a fault signal of the forklift and the fault signal meets the alarm condition, the driven installation lock fastener 2 opens the side door 1. A warning light needs to be fixed on the side door 1. The controller connects and outputs a driving signal to the installation lock fastener 2 and the warning light. When the controller cannot recognize the static QR code within the set time, the warning light is started and the display screen 5 is used to alarm. This alarm method can not only alarm the driver inside, but also let the staff outside notice it through the unfolded door. In particular, the side door 1 is a translucent frosted plate. Whether in front of or behind the vehicle, the alarm situation can be observed. The alarm linkage is reliable and the effect is obvious.

[0031] The small side door 1 is made of translucent frosted material and can also transmit light when closed, ensuring reliable lighting during the day without turning on the light source inside. In addition, the graphic of the static QR code is made of fluorescent material, so that when the vehicle briefly enters a dark place, there is no need to turn on the light source for supplementary lighting. In order to allow normal recognition at night and avoid false alarms, a light source is fixed next to the camera 4 to illuminate the static QR code. The camera 4 outputs an image signal to the display screen 5 through the controller. The controller is connected to and outputs a driving signal to the light source. When the camera 4 is working, the controller recognizes the static QR code in real time. If it cannot be recognized, the light source is turned on, and the light source is turned off after a set time is delayed after the light source is turned on.

[0032] In this embodiment, we use QR-code technology, which is divided into two types: static code and dynamic code. The design of the static code fully considers the balance between the image size and the information content, and controls the characters or text within 128. In this way, we can display the height of the forklift load when it is unloaded and the corresponding weight carried, as well as the manufacturer's website in the QR code.

[0033] In order to improve the aesthetics of the interface, we use the vCard format to display contact information. By scanning the QR code with a mobile terminal, users can easily obtain the manufacturer's contact information such as name, phone number, and position. What's more convenient is that if users use WeChat on their mobile phones to scan the QR code, they can directly save it as a contact, so that they can communicate conveniently through WeChat.

[0034] Specifically, the static QR code information includes the height of the forklift when the load is lowered and the corresponding weight of the load, the manufacturer's website, the name, phone number and job information of the manufacturer's contact person; the dynamic QR code information includes the forklift's real-time working status, maintenance records, fault status and information, and positioning information. The controller obtains the forklift's working condition information in real time, and generates a dynamic QR code from the working condition information and transmits it to the display screen 5 for display.

[0035] The system is equipped with a handheld electronic device for identifying static QR codes and dynamic QR codes. A mobile phone with the corresponding APP downloaded can be used to scan the QR code with the handheld electronic device to obtain the information of the static QR code and the dynamic QR code.

[0036] The design of dynamic codes also provides us with greater flexibility. It can generate corresponding QR codes based on real-time data, so that users can obtain the latest information. For example, we can encode the real-time working status, maintenance records and other data of the forklift into the dynamic QR code. Users only need to scan and jump to the corresponding applet to report, edit and view operations.

[0037] The report includes the inspection information of the forklift. According to the pre-designed template, the driver can complete the form by clicking "Submit" and the current operating status of the vehicle can be displayed according to the report results. Figure 2 As shown, the operation steps after the mobile terminal scans the dynamic code and enters the equipment inspection page in this embodiment. The equipment operation status can be confirmed on the mobile terminal according to the three states of normal, faulty, and under repair. When normal is selected and submitted, the corresponding equipment is displayed in green on the main page; after faulty is selected and submitted, the corresponding equipment is displayed in red on the main page; after under repair is selected and submitted, the corresponding equipment is displayed in yellow on the main page. In the inspection items category, confirm according to the set forklift electrical system, lighting system, hydraulic system and other categories. When any item is selected abnormally, if the previous equipment operation status is selected as normal, a reminder will pop up to inform the personnel to reconfirm the status of the equipment operation status.

[0038] When a vehicle malfunctions, the personnel fill in the problem description column and can attach on-site photos for technicians to judge if necessary. The inspector can fill in his own information and attach the location, and the manufacturer can arrange personnel to handle complex faults in a timely manner based on the location.

[0039] By scanning the dynamic code, personnel can also view the forklift product manual, forklift fault code knowledge base, forklift spare parts manual, forklift maintenance manual, forklift safety manual, etc. within the authorized scope. These manuals can be updated and synchronized by the forklift manufacturer, changing the traditional mode of delivering paper printing and the long-term inability to update the version. Figure 3In summary, the two-dimensional code solution in this embodiment combines the characteristics of static code and dynamic code, which not only ensures the simplicity and clarity of information, but also improves the user experience. We further simplify the communication process between users and manufacturers and improve efficiency.

[0040] In general, the present invention has the following advantages:

[0041] 1. The application of dynamic code technical documents for forklifts. Through the dynamic code that comes with the factory, the technical documents of manufacturers get rid of the traditional paper documents and the drawbacks of paper documents that are not updated in time and difficult to save. It solves the communication cost of wasting a lot of time and manpower when there is a malfunction or other need to contact the manufacturer. This technology updates and maintains documents through the background, and personnel can see the latest and correct documents in time after scanning.

[0042] 2. The role of forklift dynamic codes in inspection and fault reporting. By scanning the dynamic code, personnel can inspect the vehicle and report faults, including location, pictures and other information, saving labor costs and possible errors in manual input;

[0043] 3. Say goodbye to the limitations of the previous forklift nameplate. Warning notices and key performance points are reminded in the static code. Contacts can be added directly on WeChat by scanning the code, which improves the level of informatization;

[0044] 4. The clever combination of the side door 1 and the lock fastener, and the use of sealing pads around the small door, effectively solves the problem of waterproofing of external code scanning equipment on the forklift in rainy and snowy weather, and innovatively adopts a mechanical lock structure to prevent unauthorized people from randomly scanning the code and reading information. Only people with keys can open the door, and the camera 4 in the lock fastener is facing the QR code. When the small door is opened, the camera 4 cannot scan the code, and the image cannot be correctly displayed on the display 5, which can remind the driver of the abnormality.

[0045] The present invention is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
