When an operator overhauls a locomotive with a certain model, an overhauling work flow adopting the platform is as follows:

the operator inputs the current locomotive model and maintenance items to be maintained through the interaction unit, and after receiving the information, the control unit displays a visual operation instruction book through the interaction unit to prompt the current wireless maintenance tool to be taken, the drawer number corresponding to the tool and a specific operation animation; the operator takes out the wireless transmission tool in the corresponding drawer, meanwhile, the tool taking detection unit detects the wireless transmission tool, the detection information is transmitted to the control unit, the control unit judges whether the current wireless overhaul tool is taken out, if not, the control unit controls the interaction unit to send out an alarm prompt, such as displaying 'tool taking error' and prompting to return the wireless transmission tool with the taking error, and after the operator returns the wrong wireless transmission tool, the tool is taken again until the interaction unit displays 'tool taking is correct', and the next overhaul process can be carried out, so that strict overhaul process control is realized; meanwhile, in the overhaul process, the wireless transmission tool transmits an actual overhaul measured value (such as a size value, a torque value and the like) to the control unit, the control unit compares the actual overhaul measured value with a standard measured value range, judges whether the actual overhaul measured value is in a qualified range value, if not, the control unit controls the interaction unit to send out a disqualification prompt, so that each overhaul process is ensured to meet overhaul requirements, the error overhaul step is prevented from being continued to the next process, error transmission and accumulation are avoided, and standardized, normalized, quantized, informationized and intelligent overhaul is realized.

In one example, the wireless transmission tool is any one or more of a wireless transmission torque wrench, a wireless transmission vernier caliper, a wireless transmission depth gauge and a wireless transmission dial indicator. The wireless transmission torque wrench can be a wireless transmission electric torque wrench or a wireless transmission manual torque wrench, and is specifically configured according to user requirements. Preferably, when the wireless transmission electric torque wrench is selected, the rated torque value of the torque wrench in each procedure can be automatically adjusted according to the requirement of the torque value in each procedure, and the torque is prevented from being excessively limited or insufficient during bolt fastening by controlling the torque wrench.

Of course, as an option, the identity of the operator can be identified by inputting an account number and a password, so that the authentication management of the operator is realized.

On the basis of the above example, the output end of the control unit is connected with an electronic lock, and the electronic lock is arranged on a cabinet door for storing the wireless transmission tool, and is arranged on the cabinet door for overhauling tools or a management and control cabinet door (such as an electronic cabinet), and the electronic lock is preferably arranged on the cabinet door for storing the wireless transmission tool, the cabinet door for storing other overhauling tools and the management and control cabinet door.

Preferably, the UPS is connected with an electric quantity detection unit, and when the electric quantity of the storage battery is too low, the electric quantity is reported through an indicator lamp. In the example, 220V alternating current inverted by the UPS is output to a voltage stabilizing source of the upper computer, and working voltage is provided for the upper computer after voltage conversion by the voltage stabilizing source; further, the alternating current inverted through the UPS is changed into 24V direct current through a voltage stabilizing source, and then working voltage is provided for other devices. Of course, if the working voltage of the system components is not 24V, a voltage stabilizing module (a voltage boosting module and a voltage reducing module) may be further introduced to perform voltage conversion processing, so as to provide the working voltage for each system component. Preferably, the uninterruptible power supply comprises a plurality of uninterruptible power supply modules which respectively supply power for the tool taking and detecting unit, the identity verification unit, the control unit and the interaction unit, and the corresponding uninterruptible power supply modules can be configured for the mobile information receiving device.
