[0002] Hazardous chemicals or hazardous drugs storage cabinets are used to store hazardous chemicals or hazardous drugs. Hazardous chemicals and hazardous drugs may volatilize acidic gases or corrosive gases. However, existing hazardous goods cabinets still have the problem of insufficient safety. On the one hand, chemical cabinets are generally placed in non-crowded areas such as warehouses, laboratories, analytical chemistry rooms, and chemical storage rooms, which are often relatively closed, and the peripheral control equipment is an electronic product, which needs to be explosion-proof to meet the needs of production and use. On the other hand, the existing chemical cabinets lack early warning measures, which leads to it being too late when discovered. In addition, existing control equipment generally requires a larger current and voltage to meet the control requirements, so it is necessary to set up a multi-layer explosion-proof effect. An explosion-proof certified control terminal is not only expensive, but also has poor control capabilities and cannot meet the control requirements of multiple devices. Utility Model Content

[0017] Combination Figure 1 to Figure 2 As shown, this embodiment provides an intelligent chemical cabinet based on wireless terminal control, including multiple cabinets 1 and a master control module arranged in each cabinet 1, each of the cabinets 1 is integrated with an intelligent early warning module and a wireless communication module connected to the master control module; wherein,

[0018] The intelligent early warning module includes a plurality of sensor interfaces arranged in the cabinet 1, and the sensor interfaces are suitable for installing corresponding identification sensors according to the types of dangerous goods placed therein, so as to monitor the concentration of dangerous goods gas in the cabinet 1, and generate corresponding early warning information when the concentration exceeds a preset value;

[0019] The wireless communication module is suitable for being wirelessly connected to an external control device 2 so as to control the connection to the master control module through the external control device. The wireless communication module includes a LORA wireless transceiver module integrated in the master control module. The external control device 2 is provided with another LORA wireless transceiver module cooperating with the LORA wireless transceiver module of the cabinet 1. The external control device 2 is suitable for controlling a plurality of the cabinets 1 through signal transmission of the LORA wireless transceiver module. At the same time, each of the cabinets 1 is suitable for sending warning information and working status information to the external control device 2 through signal transmission of the LORA wireless transceiver module.

[0020] In this embodiment, the external control device 2 is a control terminal tablet. A touch screen is provided on the control terminal tablet. The user can operate the touch screen to select a certain dangerous goods cabinet to be controlled, or control all dangerous goods cabinets with one key, such as controlling the dangerous goods cabinet to circulate and exhaust, open or close locks, etc., to improve control efficiency. The touch screen can also be used to display the working status information and warning information of the cabinet 1 sent from the cabinet 1, such as temperature and humidity data, air concentration data, etc. When a dangerous goods cabinet issues an early warning, the control terminal tablet can make a voice reminder, and display the number and location of the early warning cabinet 1 and specific early warning problems, such as concentration exceeding the limit, temperature exceeding the limit, etc., so that the user can understand the problem in time outdoors. In another embodiment, the control terminal tablet can be connected to the user's mobile terminal through wireless communication, and then the user can remotely control the control terminal tablet, thereby achieving the effect of remote control of the dangerous goods cabinet.

[0021] In this embodiment, the external control device is suitable for connecting multiple cabinets 1 at the same time. In one embodiment, the same external control device 2 can control the number of cabinets 1 at the same time is less than or equal to 255. Here, since the operating current of the LORA wireless transceiver module is only a few milliamperes, the power consumption is extremely low, so each cabinet 1 is provided with a power supply that can provide 5V voltage and 1A current, which greatly improves the safety of electricity use in the entire hazardous chemical storage room. LORA is a low-power LAN wireless standard. It can propagate farther than other wireless methods under the same power consumption conditions, achieving the unity of low power consumption and long distance. It is 3 times to 5 times larger than the traditional wireless radio frequency communication distance under the same power consumption. Therefore, the utility model adopts the LORA wireless transceiver module to wirelessly control the cabinet 1 and the external control device 2, which is convenient for controlling multiple cabinets 1 through the LORA wireless transceiver module, without 4G or WiFi connection, even without network, the cabinet 1 can be operated, the transmission distance can reach 5km, and the switch status of the cabinet 1 can be monitored in real time, and voice prompts can be given.

[0022] In this embodiment, the cabinet 1 is provided with an inner liner for placing dangerous drugs or dangerous chemicals. Several placement grids can be formed in the cabinet 1 by layered partitions to facilitate the fixing and placement of dangerous goods. The cabinet 1 presents an upper and lower structure, and a master control module is integrated on the top of the cabinet 1. The cabinet 1 can also be set into a multi-layer structure for classified placement of dangerous goods of different categories and heights. A control display screen 11 is provided in front of the cabinet 1, and the control display screen 11 is connected to the master control module of the cabinet 1 so as to control the operation of the dangerous goods management cabinet through the control display screen 11. Here, the user can control the cabinet 1 through both the control display screen 11 and the external control device 2.

[0023] The cabinet 1 is provided with a sensor interface connected to the master control module. There are multiple sensor interfaces, which can be used to install various types of identification sensors. The identification sensors here can include formaldehyde sensors, VOC sensors, other gas sensors, etc., which can be replaced according to the types of dangerous goods placed in, so that the dangerous goods cabinet has good compatibility and can be used for early warning of various dangerous goods. Furthermore, the cabinet 1 can also be provided with a temperature sensor and a humidity sensor to monitor the temperature and humidity in the cabinet 1 in real time, so as to provide high temperature early warning and leakage early warning. This is because when a large amount of liquid dangerous goods leaks, the humidity in the cabinet 1 will increase significantly, and it will be judged as a leak.

[0024] In one embodiment, a plurality of cabinets 1 are suitable for interconnection. Here, the cabinets 1 are arranged in a square shape, and can be placed in an arrangement and combination manner. Adjacent cabinets 1 are connected and fixed by detachable fixing connectors, so that the cabinets 1 group form a whole, so as to save space and improve the placement stability of the dangerous goods cabinet.

[0025] Through the scheme of this embodiment, the control of the dangerous goods cabinet is made more intelligent, and multiple dangerous goods cabinets can be controlled at the same time. Early warning capabilities can be achieved according to different types of dangerous goods, and the safety is high.

[0026] It should be understood that the above are only preferred implementations of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention.

[0027] The above description of the drawings used in the implementation manner only shows certain embodiments of the utility model and should not be regarded as limiting the scope.
