In this embodiment, the method for detecting safety of a motorcycle product processing workshop includes steps S1 to S4: S1. Deploy data sensors in a motorcycle processing workshop to be inspected, use the data sensors to collect operating status information of workshop equipment in the motorcycle processing workshop, encrypt the operating status information based on the data sensors and transmit it to a preset server, so as to perform decryption and verification on the encrypted operating status information based on the server to obtain verified operating status information.

[0022] The present invention deploys data sensors in a motorcycle processing workshop to be inspected, and uses the data sensors to collect operating status information of workshop equipment in the motorcycle processing workshop, so as to obtain equipment parameters in the motorcycle processing workshop and ensure the premise of subsequent safety inspection of the motorcycle processing workshop.

[0023] Among them, the data sensor refers to a device installed in a motorcycle processing workshop, which is used to sense, collect, process and transmit the operating status information of various equipment in the workshop. The operating status information includes various parameters such as temperature, humidity, pressure, vibration, current, voltage, etc. After being collected by the data sensor, it can be transmitted to the server in real time for analysis and processing, so as to monitor and control the workshop production process and improve production efficiency and quality.

[0024] Optionally, the data sensor collects the operating status information of the workshop equipment in the motorcycle processing workshop by sensing various physical quantities in the workshop, converting them into analog signals, and amplifying and digitizing them to finally obtain the operating status information. Among them, the physical quantity refers to the quantity used to describe the physical phenomena or object characteristics in the motorcycle processing workshop, including temperature, humidity, pressure, vibration, current, voltage, etc. The analog signal is a continuously changing electrical signal, whose size and shape change with time. The electrical signal refers to the changing signal of current or voltage transmitted in the circuit, which can carry information. The digital processing is the process of converting the analog signal into a digital signal. The digital signal is a discrete, digitized signal, which is composed of a series of discrete digital samples. The advantage of the digital signal is that it can be directly processed and stored by a digital circuit, and has high accuracy and stability. The digital processing process includes three steps: sampling, quantization and encoding. Among them, the sampling is to sample the analog signal at a certain time interval and convert it into a series of values ​​at discrete time points. The quantization is to quantize the sampled signal with a certain accuracy and convert it into a series of discrete values. The encoding is to encode the quantized signal according to a certain encoding method and convert it into the digital signal.

When establishing communication, the communicating parties use the key for identity authentication and key exchange to ensure the security of communication.

[0029] Further, as an embodiment of the present invention, the decryption and verification of the encrypted running status information based on the server to obtain the verified running status data includes: querying the key of the encrypted running status information in the server; inputting the encrypted running status information and the key into a pre-built symmetric decryption algorithm to perform decryption processing of the encrypted running status information to obtain the decrypted running status information, and identifying the hash value and digital signature of the decrypted running status information; generating the verified running status information according to the hash value and the digital signature.

[0030] Among them, the symmetric decryption algorithm is a decryption method that uses the same key for encryption and decryption, the hash value is obtained by converting data of arbitrary length into a fixed-length data binary string through a hash algorithm, and the digital signature is obtained by encrypting the hash value of the data using a private key.

[0031] Optionally, the key of the encrypted running status information can be obtained by querying the exchange protocol of the pre-shared key through a query language, and the query language includes the SQL language. The pre-built symmetric decryption algorithm corresponds to the above-mentioned encryption algorithm, which can be compiled through a programming language, such as Java language. The hash value and the digital signature can be obtained by identifying the information field of the decrypted running status information.
