Description

Technical Field

[0001] The utility model relates to an automatic time calibration system, in particular to an automatic time calibration system for environment and pollution source sampling and analysis equipment. Background Art

[0002] At present, when environmental monitoring instruments report sampling and detection data, the sampling time must strictly correspond to the standard time at the time of sampling. Therefore, the calibration of the system time of environmental monitoring instruments must be based on the standard time of the national time service.

[0003] For the environmental monitoring instruments currently on the market, the instrument clock is built into the instrument's control system during system design. The control system time is set by the system's setting function. When an error occurs in the system time, it needs to be manually reset through the instrument's setting function. This makes it difficult to avoid time setting errors due to operator errors, or malicious modification of the instrument's system time due to human operation, resulting in serious distortion of the sampling data reported by the instrument. Utility Model Content

BRIEF DESCRIPTION OF THE DRAWINGS

[0016] Figure 1 It is a schematic diagram of the system composition of the utility model. DETAILED DESCRIPTION

[0017] The utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0018] like Figure 1 The automatic time calibration system for environmental and pollution source sampling and analysis equipment shown in the figure aims to redesign a standard time calibration system. When the instrument clock is calibrated, the system's intelligent terminal automatically obtains the standard time, transmits the obtained standard time to the instrument via Bluetooth or other transmission methods, and calibrates the instrument system time. All time calibration links are not manually involved, avoiding the wrong setting of the instrument system time. The environmental and pollution source sampling and analysis equipment uses the existing instrument hardware (including single-chip microcomputer, interface circuit and embedded program) in the existing system hardware structure, and cooperates with the intelligent terminal (Android or iOS system mobile phone or pad, computer and embedded software) to automatically obtain the standard time from the network time server. Of course, this design is not targeted at a specific instrument at all, and can be implemented on a variety of instruments that need to calibrate the instrument system time according to the standard time.

[0019] The clock setting module of the environment and pollution source sampling and analysis equipment is controlled by issuing a timing command through the timing controller button. As the master control module, the clock setting module is built into the sampling and analysis equipment and issues a request for online intelligent terminal after receiving the timing command; the clock setting module has a wireless communication interface, and the timing controller interacts with the control command through the wireless communication interface matched with the actual control module. This embodiment adopts a single-chip microcomputer of model STM32f103 supporting data communication. The clock setting module is realized by relying on the setting function of the instrument control system software of the environment and pollution source sampling and analysis equipment. When the clock setting module receives the timing command issued by the operator through the timing controller button, the system starts the Bluetooth communication module to connect to the intelligent terminal. After being connected, the intelligent terminal reads the standard time of the network system and transmits the time to the data buffer of the Bluetooth communication module in the form of a data packet. The Bluetooth communication module is built into the sampling and analysis equipment to receive the request of the online intelligent terminal, and the standard time automatically obtained by requesting the intelligent terminal can be automatically obtained. The FSC-986 Bluetooth module can be used. The clock setting module reads the automatically obtained standard time data through the Bluetooth communication module. Under the control of the Bluetooth communication module, the clock timing unit is built into the sampling and analysis equipment to receive the clock setting module and write the data standard time to complete the data setting of the sampling and analysis equipment system. After the time setting is completed, a clock chip such as DS1302 or DS3231 can be used for the operation of the system time.

[0020] The automatic time calibration system also includes a time calibration log recording module, which is controlled by the Bluetooth communication module and connected to the clock timing unit for information exchange, recording the time of each time calibration and the operator information, so as to facilitate the traceability and audit of the time calibration process and serve as the basis for subsequent data analysis. The storage medium can be an SD card or EEPROM chip.

[0021] The automatic time synchronization system also includes a remote control module, which remotely controls the time synchronization process of the sampling and analysis equipment, connects with the clock setting module for information exchange, sends time synchronization instructions to the clock setting module, and requests the smart terminal to automatically obtain the standard time. WiFi modules such as ESP32 or routers can be used.

[0022] The working principle of the automatic time correction system of the utility model is as follows:

[0023] The intelligent terminal automatically obtains the standard time through the network time server and transmits the time to the data buffer of the Bluetooth communication module in the form of a data packet. The Bluetooth communication module receives the data packet from the intelligent terminal and passes the data packet to the clock setting module. The clock setting module reads the automatically acquired standard time data through the Bluetooth communication module and writes it into the clock timing unit. The operator issues a time calibration command through the time calibration controller button. After receiving the time calibration command, the clock setting module issues a request for the online intelligent terminal. The clock timing unit records the time and operator information of each time calibration, which is convenient for tracing and auditing the time calibration process, and also serves as the basis for subsequent data analysis. The remote control module exchanges information with the clock setting module. The clock setting module serves as the master control module of the entire process and sends a time calibration instruction to the Bluetooth communication module at the same time to realize remote control and time calibration of the sampling and analysis equipment.

[0024] In summary, the automatic time calibration system of the utility model automatically obtains standard time through the intelligent terminal, and transmits the obtained standard time to the instrument through Bluetooth or other transmission methods to calibrate the instrument system time. All time calibration links do not involve manual participation, avoiding the wrong setting of the instrument system time. At the same time, the system also has a remote control function, which is convenient for controlling and adjusting the time calibration process of the sampling and analysis equipment.

[0025] The above implementation modes are not limitations of the present invention, and the present invention is not limited to the above examples. Any changes, modifications, additions or substitutions made by technicians in this technical field within the technical solution of the present invention also belong to the protection scope of the present invention.
