[0002] The production process of ceramic products includes clay making, slip injection molding, body drying, firing and other processes. Among them, defective products are more likely to appear in the body drying stage. After the body is transported to the drying room by a mobile cart, if the temperature, humidity, etc. around the body undergo adverse changes, the body is prone to deformation, cracking, brittleness and other problems during the drying process.

[0003] Traditionally, when blanks are placed in a drying room for drying, the environment of the drying room is detected by a detector or the changes of the blanks are observed with the naked eye, and then the environment is appropriately adjusted or the blanks are repaired. It is time-consuming, laborious and inconvenient for users to monitor the surrounding environment of each blank and directly locate the blanks that may have problems.

[0004] In order to improve the production efficiency and quality of ceramic products, it has become an urgent problem to be solved to set up a monitoring system in the ceramic drying room that can monitor the position of the green body and the environment around the green body in real time. Summary of the invention

[0005] In view of the existing technical problems, the purpose of the present invention is to provide a system for real-time monitoring and control of the drying room environment based on the Internet of Things technology, which can uniformly monitor the surrounding environment of each ceramic blank and locate the ceramic blank that may have problems, making it convenient for users to find the blank, thereby making the drying process of the ceramic blank more convenient and controllable.

[0006] To achieve the above object, the present invention provides the following technical solutions: A system for real-time monitoring and controlling the drying room environment based on the Internet of Things technology, comprising a ceramic body and a mobile cart for holding the ceramic body, each of the ceramic bodies is numbered with a body serial number that is distinguished from other ceramic bodies, the mobile cart is placed in the ceramic drying room, and is characterized in that a sensing and information sending module is fixedly connected to the mobile cart, the sensing and information sending module is built with first identification information, the ceramic drying room is installed with at least four information receiving modules, the information receiving modules are located around the mobile cart, and the four information receiving modules are respectively built with identification information A, identification information B, identification information C, and identification information D; An information binding module, used to bind the body serial number information of the ceramic body with the first identification information; A sensing and information sending module, used for sensing the environment around the ceramic body and broadcasting environmental information carrying the first identification information and the body serial number information; An information receiving module with built-in identification information A is used to receive environmental information carrying the first identification information and the blank serial number information, and is used to sense the intensity of the environmental information to obtain the intensity signal A, and then send the environmental information carrying the identification information A, the intensity signal A, the first identification information, and the blank serial number information to the background monitoring module; An information receiving module with built-in identification information B is used to receive environmental information carrying the first identification information and the blank serial number information, and is used to sense the intensity of the environmental information to obtain the intensity signal B, and then send the environmental information carrying the identification information B, the intensity signal B, the first identification information, and the blank serial number information to the background monitoring module; An information receiving module with built-in identification information C is used to receive environmental information carrying the first identification information and the blank serial number information, and is used to sense the intensity of the environmental information to obtain the intensity signal C, and then send the environmental information carrying the identification information C, the intensity signal C, the first identification information, and the blank serial number information to the background monitoring module; An information receiving module with built-in identification information D is used to receive environmental information carrying the first identification information and the blank serial number information, and is used to sense the intensity of the environmental information to obtain an intensity signal D, and then send the environmental information carrying the identification information D, the intensity signal D, the first identification information, and the blank serial number information to the background monitoring module; The background monitoring module is used to receive the information sent by the information receiving module, and then calculate the position of the sensing and information sending module according to the first identification information, identification information A, identification information B, identification information C, identification information D, intensity signal A, intensity signal B, intensity signal C, and intensity signal D, and correspond the position with the body serial number of the ceramic body and the environmental information of the ceramic body.

[0007] By adopting the above technical scheme, each ceramic blank is artificially specified in advance with a specific serial number, and the serial number represents the ceramic blank. The user can view in the background monitoring module that a set of environmental data corresponds to the blank serial number of a certain ceramic blank, and the environmental data is the surrounding environment of the ceramic blank represented by the blank serial number. Under the blank serial number, there are not only environmental data, but also the position point of the blank serial number in the ceramic drying room. If the user finds that the environmental data under a blank serial number is out of the normal environmental data range when viewing the environmental data under the blank serial number, the user can roughly judge the position of the ceramic blank represented by the blank serial number in the ceramic drying room based on the viewed position point, and then enter the drying room, walk to the position to view the ceramic blank and detect the surrounding environment.

This information binding device saves one scanning process. The blank serial number information needs to be scanned, while the first identification information only needs to be sensed. There is no need to mobilize the camera of the handheld scanning terminal to scan the code again, thereby making the information binding process more convenient.

[0021] The present invention is described in detail below in conjunction with the accompanying drawings and embodiments.

[0022] The present invention uses the terms "first", "second" or "third", "A", "B", "C", etc. to distinguish different objects rather than to describe a specific order.

[0023] The term "fixed connection" used in the present invention should be understood in a broad sense, that is, any connection method in which no displacement or relative rotation occurs between the two during use.

[0024] The focus of the present invention is to describe the relationship between the modules rather than the internal structure of some conventional items. Therefore, in the accompanying drawings, the specific internal structures of conventional existing items such as mobile carts and blanks are not drawn in detail, so these accompanying drawings cannot be identified as actual structures. For example, the "mobile cart" in the accompanying drawings can only see the body for holding the blanks, but as an existing actual "mobile cart", it should also include structures such as wheels, axles, and handlebars. Embodiment 1

[0025] See also Figure 1 , Figure 2 , Figure 3 As shown, a system for real-time monitoring and control of a drying room environment based on Internet of Things technology includes a ceramic body 1 and a mobile cart 3 for holding the ceramic body 1. Each ceramic body 1 is artificially assigned a body serial number that is distinguished from other ceramic bodies. The user sticks the prepared body serial number identification code label 2 on the mobile cart 3, and places the mobile cart 3 in a ceramic drying room 4. The mobile cart 3 is also fixedly connected with a sensing and information sending module, which can specifically be a beacon device 5 magnetically attracted to the mobile cart 3. The beacon device 5 has first identification information built in. The first identification information of each beacon device 5 is specific and can be used to represent the beacon device 5 and distinguish it from other devices. The first identification information is written into the beacon device 5 in the form of a program. In addition to the built-in first identification information, the beacon device 5 also has a first identification information identification code label 6 pasted on the outer shell of the beacon device 5. The ceramic drying room 4 is equipped with four information receiving modules, which can be specifically a gateway device 8, which is located on the side of the mobile cart 3. In order to mark and distinguish the four gateway devices, the four gateway devices are respectively built with identification information A, identification information B, identification information C, and identification information D, which are also written into the gateway device 8 in the form of programs. In addition to the above modules, there is also a background monitoring module, which is a server 9 with a programming input device and a display screen.

[0026] When in use, the user first needs to bind the information. The user holds the handheld scanning terminal 7 and scans the blank serial number identification code label 2 and the first identification information identification code label 6 in turn. After scanning, the handheld scanning terminal 7 will obtain the blank serial number information and the first identification information and send the two information to the above-mentioned server 9. The server 9 receives the blank serial number information and the first identification information, and binds the blank serial number information and the first identification information. Since the blank serial number information and the first identification information have been bound, when the beacon device 5 sends other information later, if it carries the first identification information, it will definitely carry the blank serial number information at the same time. We can combine all devices involved in binding the blank serial number information with the first identification information, collectively referred to as the information binding module.

[0027] After the green body serial number information and the first identification information are bound, the beacon device 5 first senses the environment around the ceramic green body 1 and broadcasts the environmental information carrying the first identification information and the green body serial number information to the surroundings, and then the four gateway devices 8 receive the information. Since the positions of the four gateway devices relative to the beacon device 5 are different, the signal strengths received by them will also be different. In order to distinguish the signal strength received by the beacon device 5 at a certain position from the signal strength received by the beacon device 5 at other positions, it can be described as: After receiving the environmental information carrying the first identification information and the blank serial number information, the beacon device with the identification information A built in senses the strength of the environmental information, obtains the strength signal A, and then sends the environmental information carrying the identification information A, the strength signal A, the first identification information, and the blank serial number information to the server 9; After receiving the environmental information carrying the first identification information and the blank serial number information, the beacon device with built-in identification information B senses the intensity of the environmental information, obtains the intensity signal B, and then sends the environmental information carrying the identification information B, the intensity signal B, the first identification information, and the blank serial number information to the server 9; After receiving the environmental information carrying the first identification information and the blank serial number information, the beacon device with the built-in identification information C senses the intensity of the environmental information, obtains the intensity signal C, and then sends the environmental information carrying the identification information C, the intensity signal C, the first identification information, and the blank serial number information to the above-mentioned server 9; The beacon device with built-in identification information D receives the environmental information carrying the first identification information and the blank serial number information, senses the intensity of the environmental information, obtains the intensity signal D, and then sends the environmental information carrying the identification information D, the intensity signal D, the first identification information, and the blank serial number information to the above-mentioned server 9.

[0028] The server 9 receives the information sent by the above four gateway devices, and then calculates the location of the beacon device 5 according to the first identification information, identification information A, identification information B, identification information C, identification information D, strength signal A, strength signal B, strength signal C, and strength signal D, and matches the location with the body serial number of the ceramic body 1 and the environmental information of the ceramic body 1.

[0029] Since the beacon device 5 is fixedly connected to the mobile cart 3, and the corresponding green body is placed on the mobile cart 3, the position of the green body can be roughly known by positioning the position of the beacon device 5. Therefore, the data seen on the server 9 is that a set of environmental data corresponds to the green body serial number of each ceramic green body 1. The environmental data is the surrounding environment of the ceramic green body 1 represented by the green body serial number, and also corresponds to a position point in the ceramic drying room 4, which is the approximate position of the ceramic green body 1 represented by the green body serial number.

[0030] In addition to positioning by the strength of the intensity signal, the angle signal can also be used for positioning. A gateway device 8 is selected that has not only the function of sensing information intensity but also the function of sensing information angle, and then a server 9 that can comprehensively calculate the location point through the intensity and angle of the information is selected.

[0031] See also Figure 1 , Figure 2 , Figure 4 As shown, the beacon device 5 specifically includes: a beacon sensor, a beacon wireless module, a beacon radio frequency antenna, and a beacon power supply unit.

[0032] The beacon sensor is specifically a temperature sensor and a humidity sensor. The beacon sensor senses the environmental information around the ceramic body 1 and obtains environmental information, which is specifically temperature and humidity in this embodiment. Then the beacon wireless module adds the first identification information to the sensed environmental information. Since the first identification information is bound to the body serial number information, when the first identification information is added, the body serial number information is also added. The beacon wireless module converts the environmental information carrying the first identification information and the body serial number information into radio waves that can be accepted by the gateway device 8 and then broadcasts it. The beacon radio frequency antenna serves as a transmission channel for the broadcasted information. The beacon power supply unit can be specifically a battery, which can provide electrical energy for the overall operation of the beacon device 5.

[0033] See also Figure 1 , Figure 2 , Figure 5 As shown, the gateway device 8 specifically includes a gateway RF antenna, a gateway RF processing unit, a gateway processing unit, and a gateway networking unit. There are four gateway devices 8 and they are deployed at different positions around the beacon device 5, namely, a gateway device with built-in identification information A, a gateway device with built-in identification information B, a gateway device with built-in identification information C, and a gateway device with built-in identification information D.

[0034] Among them, the gateway RF antenna in the gateway device with built-in identification information A receives the information broadcast by the above-mentioned beacon device 5, and then the gateway RF processing unit in the device senses the strength of the information received from the gateway RF antenna, generates an intensity signal A, and adds the intensity signal A to the information received from the gateway RF antenna for conversion processing. Then the gateway processing unit adds the identification information A to the information converted by the gateway RF processing unit and sends it. The gateway networking unit serves as an information transmission channel between the gateway processing unit in the gateway device with built-in identification information A and the above-mentioned server 9.

[0035] The gateway RF antenna in the gateway device with built-in identification information B receives the information broadcast by the above-mentioned beacon device 5, and then the gateway RF processing unit in the device senses the strength of the information received from the gateway RF antenna, generates an intensity signal B, and adds the intensity signal B to the information received from the gateway RF antenna for conversion processing. Then the gateway processing unit adds the identification information B to the information converted by the gateway RF processing unit and sends it. The gateway networking unit serves as an information transmission channel between the gateway processing unit in the gateway device with built-in identification information B and the above-mentioned server 9.

[0036] The gateway RF antenna in the gateway device with built-in identification information C receives the information broadcast by the above-mentioned beacon device 5, and then the gateway RF processing unit in the device senses the strength of the information received from the gateway RF antenna, generates an intensity signal C, and adds the intensity signal C to the information received from the gateway RF antenna for conversion processing. Then the gateway processing unit adds the identification information C to the information converted by the gateway RF processing unit and sends it. The gateway networking unit serves as an information transmission channel between the gateway processing unit in the gateway device with built-in identification information C and the above-mentioned server 9.

[0037] The gateway RF antenna in the gateway device with built-in identification information D receives the information broadcast by the above-mentioned beacon device 5, and then the gateway RF processing unit in the device senses the strength of the information received from the gateway RF antenna, generates an intensity signal D, and adds the intensity signal D to the information received from the gateway RF antenna for conversion processing. Then the gateway processing unit adds the identification information D to the information converted by the gateway RF processing unit and sends it. The gateway networking unit serves as an information transmission channel between the gateway processing unit in the gateway device with built-in identification information D and the above-mentioned server 9. Embodiment 2

[0038] See also Figure 1 , Figure 2 , Figure 6As shown, the other structures of the second embodiment are the same as those of the first embodiment, and the only difference is that the first identification information identification code label 6 pasted in the first embodiment is replaced by an NFC electronic label.

[0039] The NFC electronic tag is programmed with the first identification information, which is convenient for induction recognition rather than code scanning recognition. Correspondingly, in order to achieve induction recognition, the original handheld code scanning terminal 7 also needs to be equipped with an NFC electronic tag sensing module, which is an existing component and specifically includes an NFC function support chip and an NFC antenna.

[0040] The user holds the handheld scanning terminal 7, first scans and identifies the blank serial number identification code label 2, and then senses and identifies the NFC electronic tag. The handheld scanning terminal 7 sends the obtained blank serial number information and the first identification information to the above-mentioned server 9. The server 9 receives the blank serial number information and the first identification information, and binds the blank serial number information and the first identification information.

[0041] Similarly, we combine the various devices involved in the method of binding the blank serial number information and the first identification information in the second embodiment and refer to them as an information binding module. However, compared with the first embodiment, this information binding module has the above-mentioned differences in structure.

[0042] The above are only preferred embodiments of the present invention. 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. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
