[0040] The data collection device 3 is used for receiving and storing the air inlet data and the air outlet data.

[0041] It should be noted that, by adopting the magnetic attraction mode, the installation and disassembly of the detection device are more simple and convenient, and the installation and disassembly difficulty is reduced.

[0042] In an embodiment, the air inlet detection device is fixed on the cooling tower bottom plate on one side of the air inlet of the cooling tower by magnetic attraction. It should be noted that the cooling tower bottom plate is located at the bottom of the cooling tower and is used for collecting water flowing down from the filler. The air inlet of the cooling tower is located above the cooling tower bottom plate.

[0043] In a specific embodiment, the cooling tower bottom plate is a carbon steel bottom plate.

[0044] In an embodiment, the air inlet data includes humidity data; wherein the humidity data is collected by a dry and wet bulb sensor in the air inlet detection device. It should be noted that the dry and wet bulb sensor is a device for measuring air humidity. The model of the dry and wet bulb sensor is not limited in the present application, and can be selected by the person skilled in the art according to actual needs.

[0045] In an embodiment, the air inlet data has an air inlet detection timestamp; wherein the air inlet detection timestamp refers to the time information recorded by the air inlet detection device when detecting the air inlet data.

[0046] In an embodiment, the air inlet detection device is provided with a first storage module for storing the air inlet data.

[0047] In a specific embodiment, the first storage module is a memory; wherein the memory can include but is not limited to a high-speed random access memory, a non-volatile memory.

[0049] In an embodiment, the first data transmission interface is a type-c interface.

[0050] In an embodiment, as shown in Figure 2 The air outlet detection device 2 is composed of a plurality of double air outlet detection modules 21, which are fixed on the protective net at the outlet of the cooling tower by magnetic attraction.

[0051] In a specific embodiment, each double air outlet detection module 21 is fixed on the protective net at the outlet of the cooling tower by using a throwing device or a long rod.

[0052] It should be noted that since there is a certain height between the protective net at the outlet of the cooling tower and the walking channel of the cooling tower, it is difficult to hold or bind the detection device, and there is a certain safety hazard. However, using a throwing device or a long rod can quickly and accurately fix the detection device on the protective net.

[0053] In an embodiment, each double air outlet detection module is used to detect double air outlet data of the outlet of the cooling tower; wherein the double air outlet data detected by all double air outlet detection modules constitutes the air outlet data; the double air outlet data includes single-point wind speed data, air outlet temperature data, and average wind speed data.

[0054] In an embodiment, the double air outlet data detected by each double air outlet detection module has a corresponding air outlet data timestamp; wherein the air outlet data timestamp of each double air outlet detection module refers to the time information recorded by the double air outlet detection module when detecting the double air outlet data.

[0055] In an embodiment, as shown in Figures 2 to 4 Each double air outlet detection module 21 is provided with a first wind speed detection unit 211 and a second wind speed detection unit 212 in the detection order. Specifically, the wind at the outlet of the cooling tower first passes through the first wind speed detection unit 211, and then passes through the second wind speed detection unit 212.

[0056] In an embodiment, the first wind speed detection unit is a hot-wire anemometer, and the second wind speed detection unit is a vane anemometer; wherein the hot-wire anemometer is used to detect single-point wind speed data and air outlet temperature data; the vane anemometer is used to detect average wind speed data. It should be noted that the model of the hot-wire anemometer and the vane anemometer is not limited in the present application, and those skilled in the art can select according to actual needs.

[0057] It should be noted that since the wind speed measurement of the cooling tower has instability and randomness, the structure of the double air outlet detection module adopted in the present application realizes multiple backups of the test, reduces the measurement deviation under low wind conditions, and solves the problems of large fluctuation of measurement value and long measurement time under harsh working conditions.

[0058] In a specific embodiment, as shown in Figure 3 The first wind speed detection unit 211 is provided in two numbers and symmetrically arranged on the double air outlet detection module 21.

[0059] In an embodiment, as shown in Figure 3 The double air outlet detection module 21 is provided with a second data transmission interface 213 for connecting the data collection device.

[0064] In an embodiment, the air inlet detection device and the air outlet detection device are synchronous in time when detecting. Specifically, the air inlet detection time stamp of the air inlet detection device is synchronized with the air outlet detection time stamp of each double air outlet detection module.

[0065] It should be noted that since the air inlet detection device and the air outlet detection device are synchronous in time when detecting, the time of the air inlet data and the air outlet data received by the data collection device is aligned, and the technician can directly view the data. Compared with the way of exporting the data of each sensor respectively and manually integrating the data into the same table, the way of the present application is more time-saving and labor-saving.

[0066] In a specific embodiment, the time synchronization of the devices can be achieved by installing the time synchronization software in the prior art in the air inlet detection device and each double air outlet detection module. It should be noted that the time synchronization of the devices can be achieved by starting the time synchronization software uniformly after installing each detection device, which is more time-saving and labor-saving compared with manually adjusting the device time and placing the devices in the corresponding positions at the same time after starting the operation.

[0067] The following will be described in conjunction with the accompanying Figure 5 The use process of the cooling tower air inlet and outlet detection device will be described:

[0068] The air inlet detection device and each double air outlet detection module are connected with the data collection device respectively, and the time synchronization software is transmitted to the air inlet detection device and each double air outlet detection module by the data collection device. Then the air inlet detection device and each double air outlet detection module are installed at the corresponding positions of the cooling tower respectively, and the time synchronization software is started to synchronize the time of the air inlet detection device and each double air outlet detection module. Then the air inlet data and the air outlet data are detected. After the detection is completed, the air inlet detection device and each double air outlet detection module are recovered, and the air inlet detection device and each double air outlet detection module are connected with the data collection device respectively to upload the air inlet data and the air outlet data to the data collection device.

[0069] In an embodiment, the air inlet detection device and each double air outlet detection module are each assigned a device number, and each device number is recorded in the data collection device to assist in the disassembly and recovery of the detection device and the detection module. Specifically, when the air inlet detection device and each double air outlet detection module upload data to the data collection device respectively, the data collection device displays the device numbers of the devices or modules that have not uploaded data. If there are devices or modules that have not been recovered, the device numbers displayed by the data collection device can be used to determine the devices or modules that have not been recovered.
