Description

Technical Field

[0001] The utility model relates to the technical field of intelligent monitoring of temperature and humidity in chemical warehouses, in particular to intelligent monitoring equipment for temperature and humidity in chemical warehouses. Background Art

[0002] Unsuitable temperature and humidity, especially high temperature and high humidity environment, can cause serious damage to warehouse items. Therefore, keeping the temperature and humidity of the warehouse basically within a relatively standard range is an extremely important part of warehouse management. Alcohol storage has high safety range requirements for temperature and humidity. To grasp the temperature and humidity changes in the warehouse in real time and be able to change the environmental status in time to ensure the safety of alcohol storage, it is necessary to monitor the temperature and humidity of the warehouse where alcohol is stored. The traditional temperature and humidity monitoring method is to monitor through thermometers and hygrometers, collect data manually and record it in tables, which makes it impossible to issue real-time warnings when the temperature and humidity are out of range. The existing monitoring method also monitors through intelligent monitoring equipment, builds a network platform, and adapts to mobile terminal programs. When the temperature and humidity are out of range, it automatically sends a warning to the mobile terminal.

[0003] However, in actual use, this technical solution cannot perform real-time monitoring when the temperature sensor of the intelligent monitoring is out of power in the storage plant. For this reason, we propose an intelligent temperature and humidity monitoring device for chemical warehouses, which can still perform real-time temperature and humidity monitoring when the plant is short-term power outage.

[0026] In actual use, the temperature sensor 4 is used to monitor the temperature data inside the warehouse and send the temperature data to the intelligent control module 3. The humidity sensor 5 is used to monitor the air humidity data inside the warehouse and send the air humidity data to the intelligent control module 3.

At the same time, the expansion screws are aligned with the installation through holes, and the shell 101, the circuit board 2 and the electrical components on the circuit board 2 are installed on the warehouse wall.

[0034] In actual use, when there is a power outage in the warehouse and the external power supply voltage is zero, and then when the voltmeter body 801 monitors the external power supply voltage, the metal pointer 802 reads zero, so that the metal pointer 802 and the metal terminal 803 are in contact. At this time, the circuit of the lithium battery 6 used to power the circuit board 2 is turned on, and the temperature sensor 4, humidity sensor 5 and other electronic equipment are still working normally, so that when the warehouse is in a short-term power outage, the monitoring equipment can still work normally.

It should be noted that when the lithium battery 6 is discharging, the charging circuit 7 no longer charges the lithium battery 6. At this time, the charging circuit 7 is powered off. The specific structure of the charging circuit 7 is prior art and will not be elaborated here.

[0039] How it works

[0040] First, install the device. This device is installed outside the warehouse. First, install two expansion screws on the warehouse wall, and then open two probe holes on the warehouse wall, so that the probe of the temperature sensor 4 and the probe of the humidity sensor 5 are respectively inserted into the warehouse from the probe holes on the warehouse wall. At the same time, ensure that the expansion screws are aligned with the installation through holes, and complete the installation of the housing 101, the circuit board 2 and the electrical components on the circuit board 2 on the warehouse wall, and then install the cover plate 102. After the cover plate 102 is aligned, align the connecting through holes with the threaded through holes, and directly use bolts to fix the housing 101 and the cover plate 102;

[0041] Then use the device, when there is no power outage in the warehouse, such as Figure 4 As shown, the power is supplied from an external power source through the wire 104 and the plug 105, and the current flows as follows Figure 4 As shown by the arrow in the middle, at this time, the temperature sensor 4, the humidity sensor 5 and the intelligent control module 3 are working normally. The temperature sensor 4 is used to monitor the temperature data inside the warehouse and send the temperature data to the intelligent control module 3. The humidity sensor 5 is used to monitor the air humidity data inside the warehouse and send the air humidity data to the intelligent control module 3. The intelligent control module 3 has a control chip and a wireless network sending unit inside, which sends the data to the mobile terminal early warning platform. Here, the other electronic components and the early warning platform inside the intelligent control module 3 are the existing technologies in this field and are not described here. At the same time, Figure 5 As shown, the voltmeter body 801 monitors the external power supply voltage and charges the lithium battery 6 through the charging circuit 7. When the lithium battery 6 is fully charged, the charging circuit 7 no longer charges the lithium battery 6.

[0042] When the warehouse is temporarily out of power, the voltmeter body 801 monitors the external power supply voltage. At this time, the external power supply voltage is zero, and the metal pointer 802 indicates zero, so that the metal pointer 802 and the metal terminal 803 are in contact. At this time, the circuit for the lithium battery 6 to supply power to the circuit board 2 is turned on, and the current flow is as follows: Figure 6 As shown by the middle arrows, the temperature sensor 4, the humidity sensor 5 and other electronic equipment are still working normally, so that the monitoring equipment can still work normally when the warehouse is short-term power outage.

[0043] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
