Detailed Description
In order to make the technical means, the creation characteristics, the achievement purposes and the functions of the invention clearer and easier to understand, the invention is further explained by combining the drawings and the detailed implementation mode:
referring to fig. 1, the invention discloses a web-based intelligent water affair acquisition terminal, which comprises a kernel layer, a system layer and an application layer, wherein the kernel layer runs a lightweight Linux microkernel; the system layer runs a web server and exchanges data with external equipment through a hardware I/O interface; the application layer comprises a data abstraction module, a parameter module, a communication module, an equipment data acquisition module and a user database; the data abstraction module is used for extracting common characteristics among different data acquired by different devices, the parameter module is used for setting relevant parameters of the devices, and the communication module is used for carrying out communication interaction with the dispatching center; the device data acquisition module acquires data of the water supply device, transmits the data to the data abstraction module, and finally stores the data to the user database through the data writing module.
The acquisition terminal is designed based on the web, a setting interface can be displayed through the web interface, and maintenance personnel can be wirelessly connected to the web through a web browser of the handheld terminal, so that the operations of parameter modification, data acquisition increase and the like can be realized. Such as setting or modifying parameters: the system comprises a server address, a port, a local number and other parameters, and a collection terminal port corresponding to a PLC address (operation state of each pump, water inlet and outlet pressure, fault signals and the like), room temperature and humidity, noise and vibration data are set according to parameters of water supply equipment.
Preferably, the data writing module adopts a data write-back mode. The data writing has two types of direct writing and write-back, which refer to the working mode of a buffer memory, when the written data is more, the direct writing speed is slower, in the write-back rule, a cache serves as a buffer area, the cache receives the data and stops circulation, and when a system bus is available, the cache writes the data back to a main memory; in the write-through specification, the processor directly writes the data in the cache into the main memory until the data is stored in the main memory, and the write cycle cannot be completed. Write-back can maintain performance because the write is always in a "burst" of data and the time required to run is greatly reduced.
Preferably, the device data collection module collects data through a web Service. Web Service is a platform-independent, low-coupling, self-contained, programmable Web-based application for developing distributed, interoperating applications. The method has the advantages of openness and cross-platform performance, and can ensure that different applications running on different machines can exchange data or be integrated without other hardware or software, thereby reducing the design of an acquisition terminal interface and saving the cost. In addition, in the embodiment, the web Service is applied to the JSON technology, JSON is a lightweight data exchange format, has the characteristics of good readability and convenience in fast writing, can exchange data between different platforms, has high compatibility, is completely independent of a language text format, and enables JSON to become an ideal data exchange language due to the characteristics. In the embodiment, JSON is simpler than XML data, easy to read and write, small in data volume, high in transmission speed and easy to analyze, and the JSON format can be directly used for server-side codes, so that the code development amount of a server side and a client side is greatly simplified, the task is unchanged, and the web server is easy to maintain.
Preferably, the SQLITE database, i.e. the lightweight database, is installed inside, when the acquisition terminal loses contact with the server, the data is stored in the local database, and when the connection with the server is successful again, the local database and the server are synchronized, and new acquisition data are transmitted to the server from the local.
Preferably, the communication module is provided with a serial communication interface for data exchange, and a transmission line connected with the interface has the advantages of less wires and low cost, and can be used for the remote monitoring function in the embodiment.
Preferably, external hardware of the acquisition terminal is provided with an RJ45 network interface, a WIFI module and the like, and external network equipment can be connected with the acquisition terminal through the network interface to realize the functions of communicating with the server and receiving control. The RJ45 network interface comprises LAN, WLAN and other interfaces, the camera remote transmission network interface in the pump room can be accessed to the LAN interface of the acquisition terminal and transmits images to the server through network connection, and other devices (such as entrance guard and IP interphone) are accessed to the LAN interface of the acquisition terminal to realize communication and parallel control with the server.
Finally, the above embodiments are only for illustrating the technical solutions of the present invention and not for limiting, although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications or equivalent substitutions may be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all of them should be covered in the claims of the present invention.
