The positioning module 121b is configured to obtain positioning information and send the positioning information to the main control module 121 c; and also for connection to a drilling rig on which the sampling drill bit 100 is mounted, to obtain a drilling depth; wherein the drilling depth is written into the positioning information.
For example, the positioning module 121b may be connected to a controller of the drilling rig to obtain the drilling depth. It will be appreciated that the positioning module 121b may be coupled to the drilling rig in other ways to achieve the drilling depth.
The main control module 121c is used as an independent node of a block chain and is accessed into the block chain; the main control module 121c is further configured to package, sign and encrypt the soil parameter, the positioning information, the sampling time and the hardware identification code of the sensor module according to a drill bit private key obtained in advance to obtain a corresponding sampling ciphertext, and upload the sampling ciphertext and the current time to the block chain.
Specifically, the sampling time is time information when the sampling drill 100 completes soil sampling and obtains the soil parameter. The sampling ciphertext and the current time are uploaded to the block chain together, and the current time is uploaded to record the data uploading time, so that a data basis is provided for subsequent verification and the like of the sampling ciphertext, and the reliability of data can be improved in cooperation with the process of verifying the data. For example, the time interval from the sampling completion to the data uploading may be determined by comparing the uploaded current time with the sampling time recorded in the sampling ciphertext, and the sampling ciphertext may be discarded when the time interval exceeds a preset uploading time limit requirement. For the determination of the preset uploading time limit requirement, specifically, according to the operational performance of the device, the network delay condition, and the like, it is assumed that the time required by the sampling drill 100 from the sampling to the data processing is 100ms, the time required by the uploading process is 50ms, and an error time of 30ms is reserved, that is, the preset uploading time limit requirement is set to be a time interval less than 180 ms.
Specifically, a drill bit public key corresponding to the drill bit private key is issued to the block chain in advance.
According to the sampling drill bit for soil remediation provided by the embodiment 1 of the invention, the soil sensor is arranged in the sampler of the sampling drill bit, so that corresponding soil parameters can be obtained in a sampling process in real time, and the window period from sampling to parameter obtaining is shortened; the sampling drill bit is connected into the block chain as an independent node through the main control module, after the soil parameters are obtained, the sampling drill bit, the positioning information, the sampling time and the hardware identification code are packaged, signed, encrypted and uploaded into the block chain, on the basis of providing good verification for the validity of the soil parameters, the window period for obtaining the parameters from the parameters to be uploaded can be shortened by verifying the sampling time and the current uploading time, and the signature and the hardware identification code can be verified to determine whether the corresponding relation between the sampling equipment and the soil parameters is correct or not, so that the traceability of the soil parameters uploaded into the block chain is ensured, and the data transparency and the data reliability of the soil parameters are greatly improved; and the related party of the soil sampling survey can obtain the soil parameters uploaded to the block chain by accessing the block chain, thereby providing an effective path for the related party to obtain the timely and credible soil parameters.
The embodiment 2 of the invention also provides a soil information system for soil remediation, and the soil information system 2000 is an example of the sampling drill bit, which is shown in fig. 4. The soil information system 2000 includes a user terminal 2100, a system backend server 2200, and a plurality of sampling drills 100 as described in example 1. Wherein the user terminal 2100, the system backend server 2200, and each of the sampling drills 100 are independently accessed as nodes into a blockchain.
Each sampling drill bit 100 is used for collecting soil parameters and positioning information, packaging, signing and encrypting the soil parameters, the positioning information, the sampling time and the hardware identification codes of the sensor modules of the sampling drill bits 100 according to a drill bit private key obtained in advance to obtain corresponding sampling ciphertexts, and uploading the sampling ciphertexts and the current time to the block chain.
The system background server 2200 is configured to obtain the sampling ciphertext and the corresponding current time from the blockchain, and perform sampling verification on the sampling ciphertext according to the current time and the drill bit public key corresponding to the drill bit private key. In the case that the sampling verification is passed, the system backend server 2200 constructs a soil information map according to the soil parameters, the positioning information and the sampling time obtained from the sampling ciphertext. The system background server 2200 is further configured to perform signature encryption on the soil information map according to a server private key to obtain a corresponding map ciphertext, and upload the map ciphertext to the block chain.
The user terminal 2100 is configured to obtain the map ciphertext from the block chain, and perform map verification on the map ciphertext according to a server public key corresponding to the server private key. And if the map verification is passed, the user terminal 2100 acquires the soil information map from the map ciphertext and updates and displays the map.

By judging the sampling time and the current time, the time window reserved for tampering can be shortened. For example, the determination of the preset upload time limit requirement may specifically be according to the operation performance of the device, a network delay condition, and the like. Assuming that the time required by the sampling drill bit 100 to complete the sampling and data processing is 100ms, the time required by the uploading process is 50ms, and an error time of 30ms is reserved, i.e. the preset uploading time limit is set to require that the time interval is less than 180 ms; and assuming that the time required for the data tampering program to run is 70 ms. When data tampering occurs on the basis of the assumption, the time difference between the sampling time and the current time is at least 100ms +50ms +70ms =220ms, and the preset uploading time limit requirement of over 180ms is exceeded, so that tampered data is identified and discarded, the tampered data is prevented from flowing into a block chain, and data replacement is prevented from occurring from a data source.
S2213, verifying the corresponding relation between the hardware identification code and the drill bit public key according to a pre-stored corresponding relation table; and if the corresponding relation between the hardware identification code and the drill bit public key is not recorded in the corresponding relation table, judging that the corresponding relation verification fails, and discarding the sampling ciphertext.
S2214, under the condition that the difference value meets the uploading time limit requirement and the corresponding relation verification is passed, signature verification is carried out on the sampling ciphertext; and if the signature verification fails, judging that the sampling verification fails, and discarding the sampling ciphertext.
And S2215, judging that the sampling verification is passed under the condition that the signature verification is passed.
For the system background server 2200, the step of constructing a soil information map by the system background server according to the soil parameter, the positioning information and the sampling time obtained from the sampling ciphertext may specifically include step S2221 to step S2222.
S2221, selecting the soil parameters in the plurality of sampling ciphertext which pass the sampling verification according to a preset time interval.

For the user terminal 2100, the map verification specifically may include the following steps:
and performing signature verification on the map ciphertext according to the server public key, and judging that the map is verified to be passed under the condition that the signature is verified to be passed.
