Description

Technical Field

[0001] The utility model relates to the technical field of circuit board detection of sewage water quality monitors, in particular to a device for detecting circuit boards of COD monitors. Background Art

[0002] COD plays a crucial role in total pollutant control and water environment management for industrial wastewater research, sewage treatment plant performance evaluation, and urban sewage quality monitoring. With the development of society, people are increasingly prioritizing the protection of their living environment, making water quality monitoring and pollution control particularly important. With the deepening of the concepts of the Internet of Things, smart water services, the River Chief System, and grid-based systems, front-end monitoring data for rivers, lakes, urban rivers, tap water, and secondary water supplies is essential. In this new landscape, digital COD monitors can be integrated with the Internet of Things to implement grid-based water quality control and the division of responsibilities within the River Chief System.

[0003] The control module, light source and receiving PD in the circuit module play a vital role in the COD monitor. It is one of the important factors that determine whether the COD monitor equipment can detect correctly, and it is also the most critical factor. If there is a problem with the circuit module, all the subsequent work will be in vain. Therefore, the COD monitor circuit module detection device plays an important role.

[0004] There are three types of conventional detection devices, which are respectively designed to detect the control board, the light source end circuit board or the photoelectric sensor circuit board. Although the detection speed is fast and can detect whether a single circuit board is qualified, there is a lack of linkage between circuit boards. It is difficult to determine whether the three circuit boards can be used normally when installed in the COD monitor, which urgently needs to be improved. Utility Model Content

[0007] Compared with the related art, the present application has the following advantages: only a small number of electronic devices are needed to gradually detect whether the three circuit boards of the smart water meter set are qualified and whether they can be used together normally; specifically, the detection terminal issues a communication instruction to the control board to be tested to detect whether the communication interface of the control board to be tested is normal, the detection terminal issues a servo start instruction to the control board to be tested to detect whether the servo access port of the control board to be tested is normal, the detection terminal issues an ultraviolet light path detection start instruction to the control board to be tested to detect whether the control board to be tested and the light source end circuit board to be tested can be used together normally, and whether the control board to be tested and the photoelectric sensor circuit board to be tested can be used together normally for detecting the COD value of water quality, and the detection terminal issues a green light path detection start instruction to the control board to be tested to detect whether the control board to be tested and the light source end circuit board to be tested can be used together normally, and whether the control board to be tested and the photoelectric sensor circuit board to be tested can be used together normally for detecting the turbidity of water quality.

[0008] Preferably, the vertical carrier plate is fixedly mounted on one end of the bottom support plate, making the detection tooling compact and reducing the length of the second data line.

[0009] Preferably, the steering gear is installed at the upper end of the vertical carrier plate, which makes the design of the detection tooling more reasonable and streamlined.

[0010] As an improvement, a waist-shaped through hole is provided on the side of the vertical carrier plate, and the middle portion of the second data line passes through the waist-shaped through hole, so as to standardize the arrangement of the second data line.

[0011] Preferably, the mounting structure is at least two plug-in posts fixed to the side of the vertical carrier plate, so as to facilitate the taking and placing operations of the photoelectric sensor circuit board to be tested and the light source end circuit board to be tested.
