Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The data communication method provided by the application can be applied to an elevator application environment as shown in fig. 1 (the embodiment of the invention does not limit the type, brand and ladder type of the elevator). The application environment includes a first terminal 101 and a communication terminal 102. The first terminal 101 transmits communication data to the communication terminal according to the address table. The first terminal 101 and the communication terminal 102 may be various personal computers, notebook computers, smart phones, tablet computers, main control boards, portable wearable devices, or servers.
The embodiment of the invention provides a data communication method, a data communication device, computer equipment and a storage medium. The following are detailed below.
In one embodiment, as shown in FIG. 2, a method of data communication is provided. Taking the application of the method to the communication terminal in fig. 1 as an example for explanation, the method comprises the following steps:
s201, receiving data acquisition information sent by a first terminal; and the data acquisition information is obtained by the first terminal according to the address table.
The first terminal refers to a data sending terminal in the data communication process. Can be various personal computers, notebook computers, smart phones, tablet computers, main control boards and portable wearable devices.
Stored in the address table is a register address. The address table may define the content, sequence, etc. stored in each address according to the communication protocol. The first terminal fills data into the corresponding addresses according to the address sequence, and then the data to be transmitted to the communication terminal can be obtained. When the format, content, etc. of a certain address are changed, the corresponding communication data are also changed correspondingly. Therefore, with the delivery of the address table, the communication data can be changed or added without modifying the program of the communication terminal and the first terminal.
The data acquisition information refers to information returned to the communication terminal determined according to the address table, and may be specific communication data, or may be status information of the address table, or the like. When the address table in the first terminal is non-empty, communication data is generated according to the address table, so that the data acquisition information can be communication data; when the address table in the first terminal is empty (there is no address table or there is no content in the address table), the information that the address table is empty is returned to the communication terminal, and therefore, the data acquisition information may be information that the address table of the first terminal is empty.
In addition, the first terminal can automatically send data acquisition information to the communication terminal when data communication is carried out. Of course, before the communication terminal receives the data acquisition information sent by the first terminal, the communication terminal may also send a data acquisition request to the first terminal to acquire communication data from the first terminal.
S202, when the address table of the first terminal is determined to be empty according to the data acquisition information, a candidate address table is acquired.
The candidate address table refers to an address definition table which is acquired by the communication terminal in advance and used for identifying communication data. When the address table of the first terminal is empty, the first terminal needs to acquire the address table in order to generate communication data, and therefore the communication terminal needs to acquire the candidate address table and send the candidate address table to the first terminal. The candidate address table may be obtained from a memory of the communication terminal, may be obtained from a server, or may be generated by the communication terminal.
Further, when the address table of the first terminal is determined to be non-empty according to the data acquisition information, determining communication data sent by the first terminal according to the data acquisition information; and sending the communication data to the second terminal.
The communication data refers to data that the first terminal needs to send to the communication terminal or needs to send to other terminals through the communication terminal. Taking the first terminal as an elevator main control board as an example, the communication data may be elevator state data, elevator abnormal data, elevator operation data (elevator operation direction, elevator operation time, and the like), elevator control data, elevator detection data, and the like.
In addition, the second terminal refers to an acquisition end of the communication data, and can also be a definition end of the address table. The second terminal can be a computer, a control center server, a cloud server and the like.
And when the communication terminal receives the data acquisition information, the communication terminal can determine the communication data according to the rules of the address table. If the communication data needs to be sent to the second terminal, the communication terminal sends the acquired communication data to the second terminal, and data communication between the first terminal and the second terminal is achieved. Certainly, the communication data may not be sent to the second terminal, and data communication between the first terminal and the communication terminal is realized.
S203, sending the candidate address list to the first terminal; the candidate address table is used for triggering the first terminal to return corresponding communication data according to the candidate address table.
In this step, after receiving the candidate address table, the first terminal fills the corresponding data according to the definition of the address table to obtain the communication data, and returns the communication data to the communication terminal. When the communication terminal acquires the communication data, corresponding operation can be executed according to the communication data.
In this embodiment, the first terminal determines the communication data according to the address table, and the communication data can be flexibly defined through the address table, thereby facilitating continuous improvement and expansion.
In one embodiment, the step of sending the candidate address table to the first terminal includes: judging whether an address table stored in the local terminal is empty or not; if not, the stored address table is used as a candidate address table and sent to the first terminal; if yes, sending an address table acquisition request to the second terminal; the address table acquisition request is used for triggering the second terminal to return an address table; and sending the address table returned by the second terminal to the first terminal as a candidate address table.
The embodiment realizes the acquisition of the candidate address table, and the communication terminal judges whether the address table of the terminal is empty when the address table in the first terminal is empty, and if not, the address table is used as the candidate address table and sent to the address terminal; if yes, a request needs to be sent to an address table providing end (a second terminal) to obtain a candidate address table. The method and the device can ensure that the address table in the first terminal is timely acquired and corresponding communication data are generated when the address table is empty.
In one embodiment, the address table may also include version information. When the communication terminal receives the data acquisition information, if the address table of the first terminal is determined to be non-empty according to the data acquisition information, whether the address table is the latest version is judged. If the address table is the latest version, the communication data in the address table can be acquired. If the address table is not the latest version and the communication terminal stores the latest version of the address table, the communication terminal can send the latest version of the address table stored in the local terminal to the first terminal; if the communication terminal does not store the address table of the latest version, the address table of the latest version can be acquired from the second terminal. The method for acquiring the address table can ensure the real-time property of the address table so as to obtain reliable communication data. In addition, the address table can be updated according to the needs, so that the purpose of modifying the communication data is achieved.
In one embodiment, after the step of sending the address table obtaining request to the second terminal, the method further includes: and if the address table returned by the second terminal is not received, ending the data communication.
In this embodiment, the communication terminal requests the second terminal to acquire the address table without storing the address table. If the second terminal does not store the address table or the address table returns an error, the first terminal cannot acquire the address table, and the data communication can be ended at this time. And then, if the second terminal acquires or generates the address table, the address table can be automatically sent to the communication terminal. The communication terminal may also automatically send the received address table to the first terminal.
In an embodiment, when detecting that the address table of the first terminal is empty, the first terminal may also actively acquire the address table from the communication terminal or from other related terminals.
In one embodiment, as shown in fig. 3, the second terminal is a cloud server; the step of sending an address table acquisition request to the second terminal includes: and sending an address table acquisition request to the cloud server through the wireless GPRS module. The first terminal is an elevator main control board; the step of receiving the data acquisition information sent by the first terminal includes: and receiving data acquisition information sent by the elevator main control board through an RS485 interface.
Wherein, the elevator main control board and the communication terminal can also communicate through an RS232 interface and the like. The communication terminal and the cloud server can also communicate in other modes except the wireless GPRS module.
In this embodiment, the communication terminal communicates with the cloud server in a GPRS manner, and acquires an address table from the communication terminal or sends acquired communication data to the cloud server; and the communication terminal is in data communication with the elevator main control board through an RS485 interface. The data transmission efficiency between the communication terminal and the cloud server and between the communication terminal and the elevator main control board can be effectively ensured.
In order to better understand the above method, an application example of the data communication method of the present invention is described in detail below, as shown in fig. 4. In this application example, the elevator main control board passes through the RS485 interface and is connected with communication terminal, and communication terminal passes through wireless GPRS module and is connected with the high in the clouds server.
1. And the communication terminal sends a data acquisition request to the elevator main control board. If the address table of the elevator main control board is empty, the elevator main control board returns data acquisition information with the empty address table to the communication terminal to request the communication terminal to issue the address table; and if the address table is not empty, the elevator main control board determines corresponding communication data according to the definition of the address table and returns data acquisition information to the communication terminal according to the communication data.
2. The communication terminal inquires the data acquisition information of the elevator main control board, and if the elevator main control board returns the communication data, the communication terminal continues to circularly inquire the data acquisition information.
3. If the elevator main control board returns data acquisition information that the address table is empty, the communication terminal judges whether the address table is empty locally. If not, the stored address list is sent to the elevator main control board, and then the step 1 is repeated.
4. And if the address table of the communication terminal is empty, requesting the cloud server to issue the address table.
5. And if the address table of the cloud server is not empty, the cloud server issues the address table to the communication terminal. The communication terminal issues the acquired address table to the elevator main control board; and if the address table of the cloud server is empty, ending the process, generating the address table by manual processing, and continuing the step 1.
In the current elevator monitoring communication, the communication protocol is fixed, and each byte and each bit of the communication data have fixed state definitions. After the communication protocol is agreed, if the communication content needs to be changed or increased, the communication protocol can be realized only by modifying the programs of the communication terminal and the elevator main control board. Such communication mode is difficult to later stage extension, is unfavorable for the continuous improvement and the upgrading of product. The communication method provided by the embodiment increases the transmission of the address table and the content of data communication according to the address table, communication data acquired by the communication terminal can be flexibly defined through the address table, continuous improvement and expansion are facilitated, and the practical application effect is good. Meanwhile, the data communication method provided by the embodiment can be suitable for different ladders and different communication data, and is high in compatibility.
