Description
Technical Field
The invention relates to the technical field of wireless communication, in particular to a control device and a control system based on wireless communication, and application of the device and the system in the technology of internet of things and equipment intellectualization, especially application in storage devices of internet of things, smart homes, parking lot systems of internet of things, assembly line operation equipment and shared bicycles.
Background
With the progress of society and the development of science and technology, especially the development of internet of things technology, the intellectualization and the internet of things of various traditional devices have become a trend. In the technical field of the internet of things which is developed vigorously at present, the main implementation mode of the internet of things is to firstly intelligentize 'objects' in the internet of things, then communicate with the intelligent 'objects' through cloud service and an intelligent mobile terminal, and realize the remote control of the 'objects' by utilizing the intelligent mobile terminal. The intelligent mobile terminal and the cloud service are communicated in a communication mode mainly based on the existing wireless technology such as Wifi or a mobile network, and the intelligentization of the 'object' is mainly realized by arranging electronic equipment such as a tablet personal computer comprising a control unit, an input device and/or a communication interface on the 'object', receiving an instruction through the input device on the electronic equipment or communicating with the intelligent mobile terminal and the cloud service through the communication interface of the electronic equipment, so that the purpose of the Internet of things is realized.
However, the intellectualization of the "things" is realized by arranging electronic equipment on the things, so that the cost of the "things" is increased sharply or the volume and the weight are large, which is not beneficial to the development of the intellectualization process of the things. Moreover, although the electronic device realizes remote uplink interaction, that is, interaction with the mobile terminal and the cloud service is realized through the communication interface, downlink interaction control of the electronic device is realized in a circuit connection or network cable connection manner at present, and the intellectualization of articles can cause increased wiring and easy damage. Moreover, in the case of using a plurality of articles simultaneously, each article needs to be equipped with a separate electronic device, which is not only costly, but also unfavorable for resource and information sharing.
Therefore, the intelligent process of the current things cannot be well matched with the development speed of the mobile terminal and the cloud service, so that the wider and vigorous development of the internet of things technology is hindered. Therefore, how to make the intelligence of the "things" simpler, more convenient and less costly and realize the information and resource sharing among things in the process of networking, thereby promoting the further development and application of the technology of networking has become a problem to be solved in the industry.

Detailed Description
Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
Fig. 1 shows one embodiment of a control device based on wireless communication. As shown in fig. 1, the control device 20 based on wireless communication in the embodiment of the present invention includes a wireless communication module 201, a wireless transmission module 203, and a control module 202, where the control module 202 is configured to perform data processing and generate and convert a control instruction, the wireless communication module 201 is configured to control data exchange between the module 202 and an uplink device, and the wireless transmission module 202 is configured to control data exchange between the module 202 and a downlink device. The uplink device may be, for example, an intelligent terminal, a cloud terminal, and the like, and the downlink device may be, for example, an I/O board, an electric lock control board, and the like. In a specific embodiment, the wireless communication module 201 is implemented by a communication method using a public network to transmit data, for example, a method based on a mobile network such as GPRS/3G/4G/5G; the wireless transmission module 202 is implemented by a communication method based on a short-distance data communication protocol, such as a method based on a short-distance data communication protocol, such as LoRA, NB-IOT, Zigbee, or bluetooth; the control module 202 may be a single chip.
Fig. 2 shows another implementation of the control apparatus based on wireless communication, and as shown in fig. 2, the control module 202 further includes an identification unit 204 for identifying a downlink device connected thereto. The communication between the control module 202 and the uplink device is implemented based on a data transmission mode using a public network, that is, an operator of the wireless communication module 201 can assign an IP address to the uplink device to identify the uplink device, so that the uplink device can identify the control apparatus through the communication address of the wireless communication module 201, such as the IP, and the control apparatus 202 can also identify and access the uplink device in the same manner or through an access method (such as a domain name + a port number) provided by the uplink device, and does not need an additional identification method to identify the communication between the control apparatus 20 and the uplink device. However, since the control device 20 communicates with the downstream devices using the short-range data communication protocol, the control device 20 needs to be able to identify the downstream devices connected thereto, and particularly, when there are a plurality of downstream devices, to ensure that the commands or data are transmitted to the correct addresses. In this embodiment of the present invention, an identification unit 204 is disposed in the control module 202 and configured to identify the downlink device, where in a specific implementation, the identification unit 204 may be implemented as configuration information or a data storage table stored in the control module 202, where a coding address of the downlink device and a state of the downlink device are stored, and when the control module 202 sends an instruction to the downlink device, the control module generates the coding address of the downlink device in the instruction, and sends the instruction including the coding address through the wireless transmission module 203. When receiving the instruction, the downstream device can identify whether the instruction is for itself according to the coded address to decide whether to execute the instruction. It can be understood that the downlink device should be able to support the transmission protocol of the wireless transmission module 203, that is, be able to receive the data of the wireless transmission module 203 and perform parsing according to the protocol. A preferred implementation of the downlink device according to the embodiment of the present invention will be described in more detail below.
Fig. 3 shows a wireless communication-based control device in yet another implementation, as shown in fig. 3, in an embodiment of the present invention, the wireless communication-based control device 20 is configured as a dual-channel implementation, and includes a first wireless communication module 201A, a first wireless transmission module 203A, and a first control module 202A in a first communication channel, and a second wireless communication module 201B, a second wireless transmission module 203B, and a second control module 202B in a second communication channel, where the first control module 202A and the second control module 202B interact with an uplink device and a downlink device simultaneously, respectively, and perform data and instruction processing according to requirements. The first control module 202A interacts with the uplink device through the first wireless communication module 201A, and interacts with the downlink device through the first wireless transmission module 203A; the second control module 202B interacts with the uplink device and the downlink device through the second wireless communication module 201B and the second wireless transmission module 203B, respectively. Since in practical applications any module of the control device may have a problem, when one of the modules has a problem, the corresponding processing cannot be performed, which may seriously affect the user experience, especially for some applications, even cause a loss, for example, for applications where temporary articles are stored, the stored articles may be damaged due to the failure of the control device in the storage device. The embodiment of the invention adopts a double-channel design, wherein, when a component of one channel is in failure, the other channel can still work, and the interaction with the uplink equipment and the downlink equipment can not be influenced. Moreover, because the dual-channel design is on the control device, the communication between the uplink equipment and the downlink equipment is not influenced according to the original mode, and the compatibility of the whole system and the data uniformity can be ensured.
As shown in fig. 3, the first control module 202A and the second control module 202B may be configured to share the identification unit 204 in the embodiment of the present invention. For example, the identification unit 204 is set to the common configuration information. In other embodiments, separate identification units may be configured for the first control module 202A and the second control module 202B, respectively. When separate identification elements are configured for the first control module 202A and the second control module 202B, respectively, the contents of the identification elements on both modules remain consistent.

Similarly, the charging control module 208 may also be implemented by a circuit, for example, by an electronic switch circuit, that is, one end of the electronic switch is connected to the control module 202, and the other two ends of the electronic switch are respectively connected to the commercial power supply and the charging socket, so that the charging control module 208 can control the switching of the electronic switch according to the instruction of the control module 202, so as to connect or disconnect the commercial power supply and the charging socket, thereby providing the charging service for the user through the control device. In other preferred embodiments, a timing control unit (e.g., a timer, not shown) may be further disposed on the control module 202 to control the electronic switch according to a time preset by the timing control unit. Therefore, the charging service can be controlled, and the purposes of serving the public, saving energy and protecting environment are achieved.
