Detailed Description

For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more clear, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by a person of ordinary skill in the art without undue creative effort, are within the scope of protection of the present invention based on the embodiments in the present invention. It should be noted that, in the case of no conflict, the embodiments and features in the embodiments may be arbitrarily combined with each other.

As shown in connection with fig. 1 and 2, the method for locking a working device according to an embodiment of the present invention may include the following steps, which may be performed by a controller of the working device in a programmed manner:

s201, acquiring the service life time and the current running time of the operation equipment; specifically, the service life time of the operation equipment can be set to be rented when the equipment is rented, so that the service life time of the equipment can be obtained, and the service life time can be obtained through pre-selection calculation and stored for use; in addition, each time the working equipment is operated, the time of the controller can be obtained in real time, and the time is taken as the current operation time.

S202, judging whether the current running time reaches or exceeds the use expiration time; specifically, the two time parameters relate to year, month, day, time division, second and the like, the time of use T can be converted into T1 capable of performing addition and subtraction operation through calculation, the current running time T is converted into T1 capable of performing addition and subtraction operation, the time difference deltat is obtained through T1-T1, and then deltat is monitored in real time through an algorithm to judge whether deltat is smaller than or equal to 0.

S203, if the working condition information of the working equipment is reached or exceeded, judging whether the working equipment is in a working state or not according to the working condition information of the working equipment; specifically, if Δt is less than or equal to 0, it is further determined whether the working apparatus is in a working state, for example, if the working apparatus is a tower crane, whether the working apparatus is in a state of lifting the weight (one of working conditions) may be monitored.

S204, if not, controlling the operation equipment to be in a machine locking state; specifically, if the operation equipment is not in a working state, for example, the tower crane is not in a state of lifting a heavy object, a locking function is triggered, the tower crane lifting hook is operated to a 0 position, the controller of the operation equipment stops all control, and the whole machine is in a locking state.

In a specific implementation, the working device is still in a usable state when the current running time does not reach the use expiration time, i.e. does not expire, and when the working device is in a non-working state. In addition, after the current running time reaches or exceeds the use expiration time, the user equipment can be reminded of the use expiration, for example, corresponding reminding information can be sent to the control terminal or other display devices of the operation equipment or personal mobile terminals of the user after the controller of the operation equipment acts. In addition, the controller of the work equipment may employ a soft PLC (described below in connection with another embodiment).

From the above, by adopting the method for locking the operation equipment according to the embodiment of the invention, after the operation equipment is overtime, the operation equipment can be locked while the safety is considered, so that the improvement of the performance rate of the lease contract is technically facilitated, and the benefits of related parties are ensured.

On this basis, the method may further comprise the steps of: acquiring a remote locking request or an unlocking request, wherein the locking request carries locking password information, and the unlocking request carries unlocking password information; judging whether the lock secret code information carried in the lock request is matched with preset lock secret code information or judging whether the unlock secret code information carried in the unlock request is matched with preset unlock secret code information; when the locking request meets the matching requirement, the control logic of the working equipment is closed, and when the unlocking request meets the matching requirement, the control logic of the working equipment is opened. In addition, the method may further comprise the step of, before acquiring the remote lock request or the unlock request: and receiving and storing preset lock password information and preset unlocking password information so as to ensure the safe operation of the subsequent locking and unlocking links. In addition, the method may further comprise the step of, before acquiring the remote lock request or the unlock request: and verifying the access authority of the remote request host to improve the security of remote control.

As an implementation mode, the lock secret information and the unlocking secret information can be set in advance or pre-stored in the soft PLC, and data can be stored in a power-down storage mode, namely, when the system is powered down, related data can be stored, the data collected or generated in the operation of the system is not lost when the power supply is powered down, the system can recover the original working state after the power is powered up again, so that the certainty of the operation state of the system and the integrity of recorded data can be ensured, and when the power supply of the system is recovered, the on-site data can be recovered in time, and the confusion of an application system is avoided. Moreover, once the tower crane is maliciously destroyed or the soft PLC has problems, the tower crane cannot be controlled.

One specific scenario of the working equipment controller, wherein the remote host may function as a platform, on which corresponding remote control software may be configured to better implement data interaction with the soft PLC on the working equipment controller, the remote control software may provide a corresponding display interaction module, the display interaction module provides two path selections, selects "remote lock" and then inputs a lock password, a remote lock request to the working equipment controller will be formed, and correspondingly, selects "remote unlock" and then inputs an unlock password, and a remote unlock request to the working equipment controller will be formed.

The following description will be given in connection with the above scenario. The platform (remote host) can communicate with wireless receiving software of an internal non-real-time operating system (second system unit) of the operation equipment controller in a 5G/WIFI mode, and the non-real-time operating system (second system unit) and the real-time operating system (first system unit) can send platform signals to the soft PLC through mutual communication; two variables can be preset in the soft PLC, one is used for storing the lock password, and the other is used for storing the unlock password.

In the working process, when remote machine locking is needed, after logging in and passing permission verification, after passing a remote machine locking path and filling in a correct machine locking password, a program of the soft PLC can judge whether a newly input machine locking password corresponds to a previously set password variable in the program or not through for circulation after receiving a machine locking request, if the newly input machine locking password corresponds to the previously set password variable in the program, the program enters a machine locking stage, and the machine locking variable is triggered, so that the program for controlling a tower crane (operation equipment) in the soft PLC cannot be output to the tower crane, and machine locking is realized; if unlocking is needed, after the login passes the authority verification, the program of the soft PLC can judge whether the newly input unlocking password corresponds to the previously set password variable in the program through for circulation after receiving the unlocking request after passing the unlocking path and filling the correct unlocking password, if the newly input unlocking password corresponds to the previously set password variable in the program, the program enters an unlocking stage, and the unlocking variable can be triggered, so that the locked variable before the program of the control tower crane in the VPLC jumps out, and unlocking is realized.

In summary, after the working equipment controller of the embodiment of the invention is adopted, the working equipment controller can be remotely accessed, the remote control of locking and unlocking of the working equipment can be timely realized, the daily use of the working equipment is ensured, meanwhile, the danger caused by the control of non-operators is reduced, and in addition, the safety performance of the working equipment in the use process is improved in multiple aspects.

It should be noted that, in the conventional field operation devices including a tower crane, various status information needs to be acquired and a plurality of target devices need to be controlled in time, so that a control scenario is complex, a PLC (hard PLC) is generally adopted to meet reliability and flexibility, and then, with the development of industry, the hard PLC itself has some drawbacks, for example: it is difficult to build an open hardware architecture; the staff must be trained professionally for a long time to master the programming method of a certain product. Soft PLCs are rapidly developed later with the formulation and implementation of the IEC61131-3 standard in the industrial control field. The soft PLC takes a general operating system and a PC as software and hardware platforms, and realizes the control function of the traditional hardware PLC by software, namely, the control function of the PLC is packaged in the software and runs in the PC environment. The control system realizes the same function of the hardware PLC and simultaneously has various advantages of the PC. Therefore, the embodiment of the invention is purposefully improved on the basis of the function of the soft PLC based on the background.

Referring to fig. 3 and fig. 4, in the working device according to the embodiment of the present invention, the controller adopts a soft PLC control manner, for example, when the working device is a tower crane, control on various aspects of the tower crane, such as luffing control, slewing control, lifting control, and the like, may be implemented by the soft PLC.

The soft PLC can be provided with an acquisition unit, a first judgment unit, a second judgment unit and a processing unit, wherein the acquisition unit can be used for acquiring the service life time and the current running time of the operation equipment; the first judging unit may be configured to judge whether the current running time reaches or exceeds the use expiration time; the second judging unit can be used for judging whether the working equipment is in a working state according to the working condition information of the working equipment when the working equipment reaches or exceeds the working condition information; the processing unit may be configured to control the operation device to be in a locked state when the operation device is not in an operating state.

In addition, as an implementation manner, the soft PLC may be further configured with a reminding unit, which is used for reminding the user equipment of the use expiration after the current running time reaches or exceeds the use expiration time. In addition, the soft PLC may be further configured with a setting unit, which is configured to set the service life time of the working device in advance, and in actual practice, the setting unit may calculate the service life time of the device according to the service life input by the user.

In addition, in order to further improve the control performance of the working equipment (tower crane), in combination with fig. 4, the controller may specifically include a first system unit and a second system unit (not shown, real-time operating system) that are not shown in the figure, where the first system unit may be used to configure a soft PLC, the second system unit may be used to configure a non-real-time application, the second system unit and the first system unit may operate separately from each other, the first system unit may be based on the real-time operating system, the second system unit may be based on the real-time operating system due to configuring the soft PLC, and may interact with each other through an internal communication module between the first system unit and the second system unit, and the first system unit may communicate with the control terminal through the second system unit.

Further, in the implementation, the controller can adopt an upper and lower two-layer architecture of a host machine (Hypervisor) and a virtual client machine (supporting a plurality of operating systems) on the basis of controller hardware, so that the high real-time requirements of the virtual client machine can be met by utilizing the multi-core, instruction virtualization and interface virtualization technologies of the CPU; in addition, the host machine provides a safety isolation kernel for each virtual client machine with high real-time requirements, the safety isolation kernel realizes the full isolation of the virtual client machines by utilizing the multi-core, instruction virtualization and interface virtualization technologies of the CPU, the virtual client machines can directly receive IO device interrupt, access IO memory and execute special instructions, and a time-sharing scheduling mode is adopted to realize the parallel operation of a plurality of virtual client machines. The first system unit and the second system unit may each be plural. In the prior art, a common soft PLC scheme adopts a Windows+soft PLC architecture, in the scheme, the soft PLC is used as a virtual client machine to run on a host machine Windows as a real-time system, real isolation is difficult to achieve, if the Windows has system breakdown or restarting, the soft PLC is difficult to be unique, and the soft PLC enters a STOP state, so that great influence is generated on industrial field control. By adopting the scheme provided by the embodiment of the invention, the safety performance can be further improved, and meanwhile, the risk possibly generated by a user control layer and a software and hardware architecture layer is considered.

In addition, in order to further realize dynamic allocation, flexible scheduling and sharing of resources and improve utilization rate of resources, the second system unit (non-real-time operating system) may be used to configure various non-real-time applications, for example, in addition to the 4G/WIFI communication application for communicating with the control terminal, applications such as edge computing, artificial intelligence, machine vision, man-machine monitoring, gateway connection, and the like may also be configured. Therefore, the first system unit and the second system unit are respectively provided with corresponding division and operation mechanisms, and on the basis of mutual isolation, higher control and working safety performance can be achieved on the basis of more flexible and efficient utilization of hardware resources.

Fig. 4 also shows a specific scenario, where the controller of the operation device communicates with the control terminal (portable terminal) in a radio manner, where the control terminal may be configured with a login interaction module and a control module, where the login interaction module may provide a login interaction operation or information alert for a user on the control terminal, where the communication and feedback between the control terminal and the edge controller may be presented on the login interaction module, and where the user may implement control of the operation device (tower crane) through the control module after the edge controller verifies the login operation.

In summary, by adopting the machine locking method of the operation equipment, after the lease of the operation equipment is finished, the machine locking of the operation equipment can be realized while the safety is considered, so that the improvement of the performance rate of the lease contract is technically facilitated, and the benefits of related parties are ensured; in addition, based on the control mode and configuration of the soft PLC, the safety performance of the whole operation equipment can be improved on the basis of improving the utilization efficiency of hardware resources. .
