区别在于，电钻10’在出厂时，在其存储器中预存有使其能使用既定工况的工作模式，比如针对不同的材质设定达到设定扭矩即停止驱动的工作模式，每个工作模式针对一个材质，比如第一工作模式针对木材，第二工作模式针对金属材料，第三工作模式针对塑料材料；在每个工作模式下，控制器读取存储器中数据，从而实现对一些参数进行控制，比如控制电机的最大电流等。The difference is that when the electric drill 10' leaves the factory, there are pre-stored working modes in its memory so that it can use the predetermined working conditions, such as setting the working mode for different materials to stop driving when the set torque is reached. For example, the first working mode is for wood, the second working mode is for metal materials, and the third working mode is for plastic materials; in each working mode, the controller reads the data in the memory to control some parameters. Such as controlling the maximum current of the motor, etc.
作为可选方案，用户可以在笔记本电脑20’上通过无线传输的数据选择电钻10’的工作模式，当然，也可以在其他更便携的笔记本电脑20’上进行工作模式的选择。As an optional solution, the user can select the working mode of the electric drill 10' through wirelessly transmitted data on the notebook computer 20', and of course, can also select the working mode on other more portable notebook computers 20'.
作为实际应用来讲，出厂时设置的工作模式可能并不足以应付实际的工况，比如在金属材料中还分为铁质材料和铝质材料，显然用一个工作模式来针对这两种材质而言并不能很好的完成控制。作为可选方案，用户可以在笔记本电脑20’上通过无线传输的数据调整电钻10’的工作模式。As a practical application, the working mode set at the factory may not be enough to cope with the actual working conditions. For example, metal materials are divided into iron materials and aluminum materials. Obviously, one working mode is used for these two materials. Language is not very good to complete the control. As an optional solution, the user can adjust the working mode of the electric drill 10' on the notebook computer 20' through the wirelessly transmitted data.
作为更基础的应用，笔记本电脑20’可以通过无线传输的数据直接设置电钻10’的工况参数，为用户提供更个性化的工作模式。相应的，电钻10’也可以通过无线传输的数据向笔记本电脑20’反馈电钻10’的工况参数，以供用户进行参考。作为更进一步的方案，笔记本电脑20’可以比较设置和反馈的参数（或者参数范围），在反馈的参数所反映的情况超出用户所希望的状态时控制电钻10’，比如反馈的电机的电流值大于用户设定的范围时，笔记本电脑20’通过无线通讯向电钻10’发送指令，使其切断电机的电源。As a more basic application, the notebook computer 20' can directly set the working condition parameters of the electric drill 10' through the wirelessly transmitted data, so as to provide the user with a more personalized working mode. Correspondingly, the electric drill 10' can also feed back the working condition parameters of the electric drill 10' to the notebook computer 20' through wirelessly transmitted data, for reference by the user. As a further solution, the notebook computer 20' can compare the settings and the feedback parameters (or parameter ranges), and control the electric drill 10' when the situation reflected by the feedback parameters exceeds the user's desired state, such as the current value of the feedback motor When the range exceeds the range set by the user, the notebook computer 20' sends an instruction to the electric drill 10' through wireless communication to cut off the power supply of the motor.
除了工作模式之外，存储装置存储有电钻10’的说明书，笔记本电脑20’能读取电钻10’的说明书并将其显示给用户。具体而言，将电钻10’放置在能与笔记本电脑20’无线通讯的范围内，打开电钻10’和笔记本电脑20’无线通讯的功能使它们配对，然后由电钻10’的控制器向笔记本电脑20’发送指令，提示用户是否需要查看说明书，如果用户选择查看，则控制器读取说明书上传给笔记本电脑20’，或者由笔记本电脑20’直接通过通讯装置读取存储装置从而读取说明书。该模式比较适合用户初次使用时向用户提示说明书，在此之后，如果用户需要读取说明书，可以重复该过程，也可以主动地直接在笔记本电脑20’的配对设备中读取电钻10’的存储装置从而获得说明书。在笔记本电脑20’能连接到互联网时，存储装置也可以仅存储一个指向说明书的网址。作为更进一步的方案，笔记本电脑20’可以通过网络下载最新的说明书然后通过无线通讯传输给电钻10’并存储在电钻10’的存储器中。In addition to the working mode, the storage device stores the instructions of the electric drill 10', and the notebook computer 20' can read the instructions of the electric drill 10' and display it to the user. Specifically, the electric drill 10' is placed within the range of wireless communication with the notebook computer 20', the function of wireless communication between the electric drill 10' and the notebook computer 20' is turned on to make them paired, and then the controller of the electric drill 10' sends a message to the notebook computer. 20' sends an instruction to prompt the user whether to view the instructions, if the user chooses to view, the controller reads the instructions and uploads them to the notebook computer 20', or the notebook computer 20' directly reads the instructions from the storage device through the communication device. This mode is more suitable for the user to prompt the user for the manual when using it for the first time. After that, if the user needs to read the manual, the process can be repeated, or the user can actively directly read the stored data of the electric drill 10' in the paired device of the notebook computer 20'. The device thus obtains instructions. When the notebook computer 20' can be connected to the Internet, the storage device can also only store a URL pointing to the instructions. As a further solution, the notebook computer 20' can download the latest manual through the network and then transmit it to the electric drill 10' through wireless communication and store it in the memory of the electric drill 10'.
另外，对于专业用户而言，他们可能会根据自己需求对电钻10’的程序提出新的要求，以使工作在执行这些程序时更符合他们的工作需要。In addition, for professional users, they may put forward new requirements for the procedures of the electric drill 10' according to their own needs, so that the work can better meet their work needs when performing these procedures.
作为可选方案，存储装置存储有用于控制电钻10’的程序，笔记本电脑20’能读取或修改电钻10’中的程序。用户可以以读取说明书的形式读取电钻10’的内程序，然后以针对编写该程序的语言的编辑软件，对程序进行修改。这种修改可以在笔记本电脑20’上暂存然后将修改后程序存储在电钻10’的存储装置中，也可以直接在存储装置中进行修改。作为进一步的方案，存储装置可以包括可改写单元和不可改写单元两部分，将一些基础的程序，比如基础控制和安全保护的程序写入不可改写单元，以保证用户的修改不会带来使用的困扰和安全隐患，将能改善用户使用的程序，比如输出的转速等写入可改写单元，以实现用户的个性化控制。另外，还应当在不可改写单元中设置备份程序，使用户在需要时还原出厂的程序。As an optional solution, the storage device stores a program for controlling the electric drill 10', and the notebook computer 20' can read or modify the program in the electric drill 10'. The user can read the internal program of the electric drill 10' in the form of reading instructions, and then modify the program with the editing software for the language in which the program is written. This modification can be temporarily stored on the notebook computer 20' and then the modified program is stored in the storage device of the electric drill 10', or can be directly modified in the storage device. As a further solution, the storage device may include two parts: a rewritable unit and a non-rewritable unit, and some basic programs, such as basic control and security protection programs, are written into the non-rewritable unit to ensure that the user’s modification will not bring us Trouble and safety hazards, programs that can improve the user's use, such as the output speed, etc., are written into the rewritable unit to realize the user's personalized control. In addition, a backup program should also be set in the non-rewritable unit, so that the user can restore the factory-made program when needed.
作为扩展方案，用户可以直接通过笔记本电脑20’获取程序更新然后在具有权限的情况下，更新电钻10’中的程序。As an extension, the user can directly obtain the program update through the notebook computer 20' and then update the program in the electric drill 10' if he has permission.
不论在更新说明书还是在更新程序时，只要电钻10’在笔记本电脑20’能实现数据通讯的范围内，笔记本电脑20’就通过指令，使电钻10’上的诸如指示灯等指示装置向用户提示已有可以更新的程序。Regardless of updating the manual or updating the program, as long as the electric drill 10' is within the range where the notebook computer 20' can realize data communication, the notebook computer 20' will prompt the user through instructions such as indicator lights on the electric drill 10'. There are already programs that can be updated.
作为可选方案，存储装置存储有电钻10’正常工作时的工具特性的参数范围；控制器或笔记本电脑20’判断由检测装置检测的工具特性的参数是否在参数范围内以判断电钻10’是否发生故障；笔记本电脑20’将故障信息提示给用户。具体而言，用于判断电钻10’是否发生故障的工具特性的参数包括电机的电流。当电机电流过大时可以向用户进行提示。As an optional solution, the storage device stores the parameter range of the tool characteristic when the electric drill 10' is working normally; the controller or the notebook computer 20' judges whether the parameter of the tool characteristic detected by the detection device is within the parameter range to judge whether the electric drill 10' A fault occurs; the notebook computer 20' prompts the user with fault information. Specifically, the parameters of the tool characteristics used to determine whether the electric drill 10' fails include the current of the motor. When the motor current is too large, it can prompt the user.
更具体而言，检测装置还可以包括其他的传感器，比如震动传感器、噪声传感器等，当它们检测电钻10’的传动机构震动或噪声超标时，也可以判定电钻10’发生了故障。当然，也可以根据多个数据的组合判断故障，比如电机电流在正常范围，但是检测装置检测电钻10’钻头的转速小于正常值或静止，可以判定传动机构失效，从而向用户提示故障。More specifically, the detection device may also include other sensors, such as vibration sensors, noise sensors, etc., and when they detect that the vibration or noise of the transmission mechanism of the electric drill 10' exceeds the standard, it can also be determined that the electric drill 10' has broken down. Of course, the fault can also be judged based on the combination of multiple data, such as the motor current is within the normal range, but the detection device detects that the speed of the drill bit of the electric drill 10' is lower than the normal value or is stationary, and it can be determined that the transmission mechanism is invalid, thereby prompting the user for a fault.
钻头本身作为电钻10’的工具附件，对其位置进行检测也可以判断电钻10’是否发生故障或是否被非正常的使用，比如钻头脱离或未安装钻头。The drill bit itself is used as a tool accessory of the electric drill 10', and its position detection can also determine whether the electric drill 10' breaks down or whether it is used abnormally, such as the drill bit breaks away or the drill bit is not installed.
对于图1所示的割草机10和移动电话20而言也可以实现故障检测功能，比如当检测装置检测到由于割草刀片撞击割草机10底盘的声音时，移动电话20中处理器可以提示用户也可以直接控制割草机10停止运行以保证安全。或者，利用位置传感器检测割草刀片的位置，当发现割草刀片的位置处于非正常状态时，即采用故障处理的控制。For lawnmower 10 shown in Fig. 1 and mobile phone 20, fault detection function can also be realized, for example, when detection device detects the sound due to mowing blade bumping lawnmower 10 chassis, processor in mobile phone 20 can Prompting the user can also directly control the mower 10 to stop running to ensure safety. Alternatively, the position sensor is used to detect the position of the mowing blade, and when the position of the mowing blade is found to be in an abnormal state, the control of fault handling is adopted.
作为可选方案，电钻10’中的检测装置也可以包括位置传感器，该位置传感器用于检测电钻10’的位置变化从而判断电钻10’是否出现故障。位置传感器可以采用陀螺仪和定位装置的组合。As an optional solution, the detecting device in the electric drill 10' may also include a position sensor, which is used to detect the position change of the electric drill 10' so as to judge whether the electric drill 10' breaks down. The position sensor can use a combination of gyroscopes and positioning devices.
具体而言，用于判断电钻10’是否发生故障的工具特性的参数包括：电钻10’的位置、电钻10’位置变化的速度、电钻10’位置变化的加速度。当检测装置检测到电钻10’经过剧烈冲击时，一般是电钻10’发生跌落，笔记本电脑20’会综合速度加速度等参数和预存的可承受的参数进行比较，如果超出允许的范围，则提示用户可能发生故障，建议用户检修，同时锁定电机，使工具不再工作。当然，在割草机10也可以采用相类似的方案。Specifically, the parameters of tool characteristics used to determine whether the electric drill 10' fails include: the position of the electric drill 10', the speed at which the position of the electric drill 10' changes, and the acceleration at which the position of the electric drill 10' changes. When the detection device detects that the electric drill 10' has undergone a severe impact, it is generally that the electric drill 10' has fallen, and the notebook computer 20' will compare the parameters such as speed and acceleration with the pre-stored tolerable parameters, and if it exceeds the allowable range, it will prompt the user A malfunction may occur and the user is advised to service it while locking the motor so that the tool will no longer work. Of course, a similar scheme can also be adopted in the mower 10 .
需要说明的是，在以上两种方案中，通讯装置既能在检测装置检测时同步将数据传输给数据接收子系统；也可以采用检测装置能将检测数据先暂存在存储装置中，通讯装置能将存储在存储装置中数据传输给数据接收子系统的方案。It should be noted that, in the above two schemes, the communication device can not only transmit the data to the data receiving subsystem synchronously when the detection device detects; the detection device can also temporarily store the detection data in the storage device first, and the communication device can A scheme for transferring data stored in a storage device to a data receiving subsystem.
