The detection device (Profitrace) of the field bus network of the field bus control system (ProfiBus) has the function of an oscilloscope, can also realize communication voltage measurement and message reading, and is a main tool for overhauling and checking the field bus network. At present, the Profitrace device can only realize one-to-one detection. When a communication fault occurs in the fieldbus network, a professional is required to carry the Profitrace device and related tools to carry out connection detection on the fieldbus communication cabinet where the fault network is located. Fieldbus cabinets are typically located near field devices, also known as local cabinets, and are relatively decentralized and numerous. If the local communication cabinets of the field bus network are detected one by one, a large amount of time cost and labor cost are needed to be consumed, and the fault diagnosis is not timely and low in efficiency.

In view of the above, the present disclosure provides an integrated detection device and system for a fieldbus network to solve the above technical problems.

The present disclosure is described below with reference to specific examples.

Referring to fig. 1, the present disclosure provides a testing integrated device 100 for a fieldbus network, where the testing integrated device 100 includes a first communication interface 101, a plurality of second communication interfaces 102, and a connection unit 103. The first communication interface 101 is used for being connected with a detection device of a field bus network, the second communication interfaces 102 are used for being connected with a plurality of field bus communication cabinets of the field bus network, and the first communication interface 101 is connected with the second communication interfaces 102 through the connection unit 103, so that the detection device can detect the field bus communication cabinets through the first communication interface 101, the connection unit 103 and the second communication interfaces 102.

By adopting the detection integrated device for the field bus network, the detection device can detect a plurality of field bus communication cabinets through the detection integrated device, when the field bus network has communication faults, a professional can directly use the detection device to detect the field bus communication cabinets through the detection integrated device for the field bus network, and does not need to carry the detection device and related tools to connect and check the field bus communication cabinet where the fault network is located, so that the fault detection is carried out in time, and the detection efficiency is improved.

Illustratively, the buttons may include two states of "on" and "off", each button corresponding to a second communication interface, the second communication interface being connected to a corresponding fieldbus communication cabinet. An operator can control the communication between the first communication interface and the plurality of second communication interfaces by switching the state of the button, so as to control the field bus communication cabinet detected by the detection device. When the button state is 'on', the first communication interface establishes communication with the second communication interface corresponding to the button, the detection device can carry out communication detection on the field bus communication cabinet corresponding to the second communication interface, and when the button state is 'off', the first communication interface and the second communication interface corresponding to the button are disconnected from communication.

It should be noted that, in order to ensure that the detection process is not interfered, generally, only one fieldbus communication cabinet is detected each time, that is, when the communication detection of the fieldbus network is performed, the button state corresponding to the detected fieldbus communication cabinet is "on", and the button states corresponding to the other fieldbus communication cabinets are "off". Of course, if there are other methods for avoiding interference, a plurality of fieldbus communication cabinets may also be detected at the same time, which is not limited in this disclosure.

In a possible manner, referring to fig. 2, the connection unit 103 includes a plurality of terminal resistors 202, the plurality of terminal resistors correspond to the plurality of buttons one by one, and the plurality of terminal resistors are connected to the plurality of second communication interfaces one by one. And aiming at each terminal resistor, the transfer switch is used for controlling the input level of the terminal resistor through a button so as to control the communication between the first communication interface and the plurality of second communication interfaces, wherein the terminal resistor is switched on when the terminal resistor is at a high level and switched off when the terminal resistor is at a low level.

Illustratively, the buttons may include two states of "on" and "off", each button corresponds to a terminal resistor, each terminal resistor is connected to a corresponding second communication interface, and the second communication interface is connected to a corresponding fieldbus communication cabinet. An operator can control the input level of the terminal resistor by switching the state of the button so as to control the communication between the first communication interface and the plurality of second communication interfaces, thereby controlling the field bus communication cabinet detected by the detection device. When the button state is 'on', the input level of the terminal resistor is high level to turn on the circuit, the first communication interface establishes communication with the second communication interface corresponding to the button, and the detection device can perform communication detection on the field bus communication cabinet corresponding to the second communication interface. When the button state is 'off', the input level of the terminal resistor is low level to disconnect the circuit, and the first communication interface and the second communication interface corresponding to the button are disconnected from communication.

When the button state is 'on', the input level of the CMOS circuit is low level, the PMOS tube is conducted, the NMOS tube is cut off, and high level is output. The CMOS circuit outputs a high-level conduction circuit to the terminal resistor, the first communication interface establishes communication with the second communication interface corresponding to the button, and the detection device can perform communication detection on the field bus communication cabinet corresponding to the second communication interface. When the button state is 'off', the input level of the CMOS circuit is high level, the PMOS tube is cut off, the NMOS tube is conducted, and low level is output. The CMOS circuit outputs a low-level disconnection circuit to the terminal resistor, and the first communication interface is disconnected from the second communication interface corresponding to the button.

In a possible way, the detection integrated device comprises a closed box.

Illustratively, the closed box body can be made of explosion-proof and corrosion-proof GRP SMC material (composite material of glass fiber reinforced plastics and sheet molding compound) or stainless steel material, and the disclosure does not limit the material.

In a possible manner, the detection integrated device comprises an indicator light for indicating the status of the detection integrated device.
