[0025] Industrial process control systems require process parameter acquisition and processing devices to collect and calculate parameters such as temperature, pressure, flow rate, liquid level, and speed, before uploading the data to the control system network. To periodically check the operating status, acquisition accuracy, and calculation accuracy of these devices, calibration is necessary. Throughout the device's lifespan, multiple calibrations are often required to ensure its performance. Conventional calibration methods involve repeated disconnection and reconnection of numerous signal cables, which are prone to errors. To prevent incorrect cable connections from causing inability to obtain process system parameters or damage to the system, additional wiring checks are required after each connection, further increasing the workload and resulting in extremely low efficiency. Therefore, it is necessary to propose a rationally designed process parameter acquisition and processing device that effectively addresses these issues and facilitates calibration.

The power supply module provides power to the working module and the controller module. The external connection module or the standard inspection module is connected to the working module through the internal connection module to perform process parameter acquisition and calculation or to acquire inspection process parameters.

[0029] The internal connection module includes at least a third cable assembly. The internal connection module and the external connection module are connected via a quick-plug connector, and the internal connection module and the standard inspection module are also connected via a quick-plug connector.

[0030] Specifically, the first cable assembly is plugged into and unplugged with the first multi-core connector A1 in the first interconnect module, the second cable assembly is plugged into and unplugged with the third multi-core connector B1 in the second interconnect module, and the third cable assembly can optionally be plugged into and unplugged with the second multi-core connector A2 in the first interconnect module to enter the normal operation mode; the third cable assembly can also optionally be plugged into and unplugged with the fourth multi-core connector B2 in the second interconnect module to enter the inspection operation mode.

[0031] The working module includes a temperature transmitter module, an isolator module, a speed converter module, and a calculator module; the controller module is connected to the temperature transmitter module, the isolator module, the speed converter module, and the calculator module respectively. A third cable assembly is connected to the temperature transmitter module, the isolator module, the speed converter module, and the calculator module respectively.

[0032] Specifically, in this embodiment, the third cable assembly is connected to the temperature transmitter module, the isolator module, the speed converter module, and the calculator module. The other end of the third module is connected to either the external connection module or the standard verification module. The selection of connection to the external connection module or the standard verification module determines whether the signal connected to the working module is a process system operation acquisition signal or a parameter calibration signal, thereby controlling whether the process parameter acquisition and processing device is in normal operation or verification mode. When the third cable assembly is connected to the first interconnect module in the external connection module, the external sensor is connected to the third cable assembly through the first cable assembly and the first interconnect module, and the process parameter acquisition and processing device enters normal operation mode.

The controller then uploads these signals to the upper-level control system to complete the process parameter acquisition and calculation.

[0035] When the third cable assembly is plugged into and unplugged into the fourth multi-core connector B2 in the second interconnection module, and the inspection working mode is entered, the standard calibration device simulates an external real sensor, generating a standard 4-20mA current signal, a Pt100 platinum resistance signal, and a rotational speed frequency signal, which are then transmitted to the working module for data verification via the third cable assembly.

The temperature transmitter module, the isolator module, the speed converter module, the calculator module, and the controller module are connected via CAN communication. The controller module is responsible for converting the acquired 4-20mA current signal, Pt100 platinum resistance signal, speed frequency signal, etc., into digital signals and uploading them to the controller module. The controller then uploads these signals to the upper-level control system to verify the process parameter acquisition.

[0036] This invention provides a process parameter acquisition and processing device that is easy to inspect. The working module includes a temperature transmitter module, an isolator module, a speed converter module, and a calculator module, all connected to a controller module. A third cable assembly is connected to these modules, and the other end of the third module is connected to either an external connection module or a standard verification module.
