Background
With the rapid development of information technology, the internet of things (IoT) has entered into various industries, and digitization is becoming a new engine of engineering machinery development. Because engineering machinery equipment is high in price and the use frequency of a single engineering manufacturer is low, equipment renting mode is mainly adopted in the engineering industry to improve equipment use rate and save engineering investment sum.
As the rental market of engineering machines expands gradually, there is a certain rental risk for both parties: the renter can rent engineering machinery and then use the engineering machinery by the user, and some users with poor reputation often have the phenomenon of deliberately damaging the machinery and using the machinery beyond the scope; in addition, the phenomenon that equipment is lost or stolen due to the fact that a user takes care of the equipment is unfavorable is caused, so that the interest of a renter is lost; the using method comprises the following steps: when the leased engineering machinery is a foreign machine, especially a large machine or is leased for a long distance, the mechanical performance verification cannot be performed in time, some leasers with poor credit lease the faulty machine, and then the use damage of the user is taken as the claim of the user, so that the benefit loss of the user is caused.
In order to solve the technical problems, a great deal of effort is made, chinese patent discloses a monitoring system for internet of things of post-installation of engineering machinery, publication No. CN111435232B, which proposes to install a monitoring terminal on each engineering machinery, then pair-connect the monitoring terminal with a monitoring center and a mobile terminal, set a usage range in the monitoring center, the monitoring terminals identify a location position to solve the problem of over-range usage of a user, and the monitoring terminals can communicate with each other, when long-distance transmission is invalid, short-distance wireless signals can be sent to other machines around through a third transmission device, thereby eliminating the monitoring blind area and finding lost equipment. However, the foregoing solution still has some drawbacks, for example, the foregoing solution must install a monitoring terminal on the rental device, and the claimed effect cannot be achieved without the monitoring terminal, and when the monitoring mobile terminal is easily removed, the lost/stolen device cannot be recovered. In addition, the above solution does not really solve the problem of mechanical renting of the fault, and although the initial performance inspection is mentioned, firstly, the monitoring terminal is mastered by the renter, is easy to be controlled by the renter, is easy to cheat, and is unfair to the user; secondly, the performance inspection can only check the running performance, can be used for checking whether the equipment is in good operation at present, and can not ensure whether the equipment is in fault before, and secondary faults are easy to occur if the places in fault are not well processed, and can only be used for checking some basic performance information, can not check the appearance, and the damage of the monitored parts, and the like, and the users are required to perform manual inspection before renting, so that the additional maintenance cost of the same renting object and the same problem is repeatedly collected by bad renters for different users due to different familiarity degree and inspection means of renters and users to the renting equipment.

The invention will be described in further detail with reference to the drawings and the detailed description. The scheme provides a targeted solution to some problems existing in the existing engineering machinery leasing market, and mainly aims at providing an engineering machinery Internet of things monitoring system based on a blockchain.
Example 1
As shown in fig. 1, the system includes a work machine platform 1, a mobile terminal 2, and a machine-mounted monitoring terminal 3 capable of communicating with the work machine platform 1 and the mobile terminal 2.

Specifically, the equipment information provided by the equipment manufacturer platform 4 to the engineering machine platform 1 includes data, instructions and communication capability of the corresponding equipment, and when the renter purchases equipment from the equipment manufacturer by himself or in a financing and renting mode, the equipment manufacturer sends the equipment information of the corresponding equipment to the engineering machine platform 1 of the corresponding renter through the equipment manufacturer platform 4.
As shown in fig. 2, the engineering machine platform 1 determines the communication capability of the corresponding device according to the device information, if the device has a wireless communication capability capable of communicating with the engineering machine platform 1 and the mobile terminal 2, the device controller 7 of the corresponding device is used as the monitoring terminal 3 to collect information, the engineering machine platform 1 is directly connected with the corresponding device controller 7 in a wireless manner, the device controller 7 is a controller of the device itself, and is connected with the device action component 8 of the device, such as a sound box, a loudspeaker, a motor, and the like. The system can utilize the configuration of the mechanical equipment without installing a monitoring terminal on each mechanical equipment.
If the equipment does not have wireless communication capability capable of communicating with the engineering mechanical platform 1 and the mobile terminal 2, the monitoring terminal 3 is connected to the equipment controller 7, the engineering mechanical platform 1 judges the protocol form of the corresponding equipment according to the equipment information, and instructs the monitoring terminal 3 to communicate with the equipment controller 7 in the corresponding protocol, for example, through the standard CAN protocol, through the connection with the equipment controller, the sound box, the loudspeaker and other controlled equipment such as a motor of the equipment CAN be controlled; . The engineering machinery platform 1 records the number of the monitoring terminal 3 and binds the corresponding relation between the monitoring terminal 3 and the equipment.
Likewise, the monitoring terminal 3 includes a monitoring controller, a power module, a positioning module, a wireless module and a storage module, and the monitoring terminal 3 is connected to the engineering machinery platform 1, the blockchain platform 5 and the mobile terminal 2 through the wireless module. There may be two kinds of wireless modules, one is a remote wireless module, such as Wifi, GPRS, etc., for communicating with the engineering machinery platform 1 and the blockchain platform 5, and one is a short-range wireless module, such as local area network Wifi, bluetooth, lora, etc., for communicating with the mobile terminal 2. The mobile terminal 2 has two communication capabilities, one is a remote communication capability for communicating with the engineering machinery platform 1, the other is a short-distance communication capability for communicating with the monitoring terminal 3, the mobile terminal 2 comprises a mobile terminal used by a renter and a mobile terminal used by a user, and the engineering machinery platform 1 records the corresponding relation between the mobile terminal and the mobile terminal user.
Preferably, the monitor terminal 3 is also connected to the device power supply 6 of the device to form a dual power supply system composed of the device power supply 6 and its own power supply.
Taking the installation of the monitoring terminal 3 as an example, after one device is installed and bound with the monitoring terminal 3, the monitoring terminal 3 can send control information to the device controller 7 according to the control instructions of the engineering machinery cloud platform 1 and the mobile terminal 2 so as to participate in the control of the device, for example, language intelligent broadcasting, horn car searching, remote locking, low-electricity intelligent voice prompt and the like can be realized under corresponding renting and using scenes, for example, data acquisition can be carried out according to the acquisition instructions issued by the engineering machinery cloud platform 1, and the data acquisition can be reported to the blockchain platform 5 and the corresponding engineering machinery cloud platform 1 according to a designated period, and in an application scene, the engineering machinery cloud platform 1 can monitor and record the working state of the device according to the position information, working condition information, alarm information and other information reported by the monitoring terminal 3, and trigger corresponding processing logic according to the business rules so as to prompt a user to carry out various remote instruction treatments. Space-time use restrictions of the mechanical device and the like can also be set through the mobile terminal 2 and the mechanical cloud platform.
Preferably, the monitor terminal 3 has a disassembly sensing module, which is configured to report disassembly information to the engineering machinery platform 1 when a disassembly motion is sensed, and locally send an audible and visual alarm command to the device controller 7 to operate the device to perform an audible and visual alarm, for example, to control the sound box to perform an audible and visual alarm. In this way, the monitor terminal 3 can be prevented from being detached. The disassembly sensing module may be a pressure sensing module installed between the monitoring terminal and the mechanical device and connected to the monitoring terminal controller, and when the monitoring terminal 3 is disassembled, sensing data of the pressure sensing module may change. Of course, the disassembly sensing module can also take other forms, such as a photoelectric sensing module.
Example two
As shown in fig. 3, the embodiment is similar to the embodiment, and is different in that the embodiment can further play a role in preventing disassembly, and the specific implementation method is as follows:
and sending a starting condition to the equipment controller every time the monitoring terminal is connected with the equipment controller, wherein the starting condition is that the current monitoring terminal is connected.
And detecting whether the equipment controller 7 is connected with the corresponding monitoring terminal 3 at present when the equipment controller 7 is started each time, if so, considering that the starting condition is met, starting successfully, and if not, prompting that the monitoring terminal 3 is disassembled. It should be understood by those skilled in the art that if the device controller 7 is connected to the monitor terminal 3, the two parties can detect each other, and this embodiment uses this to achieve the anti-disassembly purpose, once the device controller 7 is connected to the monitor terminal 3, the device controller 7 recognizes that the monitor terminal 3 is calibrated, detects the monitor terminal 3 once every time, and the device controller 7 cannot be successfully started without detecting the monitor terminal 3 before receiving the instruction for releasing the start condition, thereby achieving the anti-disassembly purpose. In this embodiment, when the disassembly action is detected, words such as "the disassembly monitoring terminal 3 will cause the device to be unusable" may be uttered in voice to prevent disassembly.
The embodiment is improved on the basis of the first embodiment, when the monitoring terminal 3 is detached, firstly, the detachment information is reported, and the audible and visual alarm is sent out to prevent the detachment, so that the detachment can be prevented in a general way, but the detachment can not be prevented, at this time, the method of the embodiment has the second line-proof effect, so that the device cannot be used after the monitoring terminal 3 is detached, and the bad user can be prevented from maliciously detaching the monitoring terminal 3.
If the monitoring terminal 3 is to be disassembled, the engineering machinery platform sends an instruction for releasing the starting condition to the equipment controller through the monitoring terminal 3, the equipment controller 7 verifies whether the instruction is sent by the engineering machinery platform 1, if yes, the instruction is executed to release the starting condition, and at the moment, the monitoring terminal can be disassembled. Preferably, the instruction is verified by adopting a signature key pair mode, the engineering machinery platform signs the instruction by using a private key, and the equipment controller decrypts by using a corresponding public key to complete the identity verification of the engineering machinery platform.

the mobile terminal 2 transmits a prompt tone after receiving the broadcast response.
When the mechanical equipment cannot be found, the user can use the terminal equipment 3 to inform the factory mechanical platform 1 of remotely issuing instructions to enable the factory mechanical platform to perform acousto-optic response, such as playing car searching audio, car-mounted loudspeaker and the like. When the equipment is located in a remote wireless blind area, the position cannot be reported, and a remote instruction cannot be received, the mode can be used for searching the vehicle. By utilizing a short-distance wireless communication mode, even if equipment enters a remote wireless network blind area, lost equipment can be found out rapidly. In addition, as the information such as the state information of the equipment is uploaded to the blockchain platform, the leasing parties can fairly divide responsibility according to the final audible and visual alarm, the positioning position and the like, and real-time, high-precision accuracy and fine management of the equipment are realized.
In addition, the device check can be performed based on the mobile terminal 2, and the specific implementation method is as follows:
