Since some core technologies of each huge brought to the prosperous investment and construction of factories cannot be mastered, the cost of products is high, and the development of local enterprises is not disturbed.
It is always desirable for passengers to wait for an elevator for a short time, with little time spent in the car. However, for the management department of the elevator, it is desirable to reduce the energy consumption of the elevator as much as possible and further reduce the maintenance cost when the riding requirement is satisfied. In the face of the demands of multiple parties, it is clearly unreasonable to consider the demands of one party alone. It is easy to cause great waste.

FIG. 1 is a schematic diagram of the present invention.
Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1, an internet of things remote calling system comprises a mobile terminal, a landing calling board, a car operating panel and a cloud server; the mobile terminal sends an elevator appointment signal to a cloud server, the cloud server receives the appointment signal, and the appointment signal is transmitted to a proper landing external calling board through calculation to perform elevator call registration; and after the elevator arrives at the floor, the cloud server sends reservation information to a car control panel of the elevator to register a target floor, and controls the corresponding elevator to arrive at a preset place.
The advantage of using the cloud service is that enterprises can quickly obtain the service in a short time by the service provided by the cloud service supplier without investing a large amount of fixed asset purchasing software and hardware and increasing information management personnel. This will help the operation of some enterprises with the time and second. The cloud service mode builds a platform for data fusion in multiple fields of the economic society, and potential relevant relations and development trends of data information are mined, so that scientific judgment and prediction of governments can be promoted. In a cloud service mode, data are stored in a cloud end in a centralized mode, data storage media are difficult to obtain through a physical method, and the risk of data leakage can be effectively reduced. In addition, the cloud service provider can uniformly manage the cloud user data according to the user requirements. In 2013, the scale of the Chinese cloud computing market exceeds 1100 million yuan, and related enterprises of the Chinese cloud computing exceed 200 families, so that the research and development and industrialization capabilities of the cloud computing technology are basically formed, and the cloud computing industry pattern and enterprise groups are preliminarily formed.
With the virtualization technology, data backup and backup of an enterprise in the cloud can be guaranteed to a certain extent. The enterprise is willing to put data and application programs in the cloud, and all branch companies can obtain services in time through the network, so that the requirement of on-demand service (service on demand) is met, and the operation efficiency of the whole company is accelerated.
In this embodiment, the mobile terminal is a mobile phone equipped with an Android system, and the Android system adopts a layered architecture and is divided into four layers. The bottom layer is a Linux kernel layer; a system operating library is arranged above the Linux kernel layer, and a plurality of basic libraries are provided for developers; then an application program framework is arranged, and some components related to Android development are included in the layer; the top layer is an application program layer, which contains an application program installed in the equipment of the Android system and is mainly responsible for interaction with the user. And a piece of mobile phone software capable of reserving the elevator is installed in the application program.
The landing calling board is a controlled end and comprises a development board of an embedded Iot system based on an ARM cortex M3 core board, application programs are developed by adopting a C programming language, and the developed application programs run on a circuit board of the embedded Iot system based on the ARM cortex M3 core board.
In the cloud server, data communication is required to be carried out between the mobile terminal and the hall call board and the car control panel, and all data are processed and forwarded through the cloud server. The network communication of the remote control system adopted by the application is based on UDP/CoAP protocol. CoAP is a generic term for a restricted Application Protocol (Constrained Application Protocol). Experts have predicted that more devices will be interconnected in recent years and the number of such devices will far exceed the number of humans. In this large context, the internet of things and M2M technology have come to the fore. Although it is convenient and easy for people to connect to the internet, it is very difficult for those miniature devices to access the internet. In the world currently composed of PCs, the information exchange is realized by TCP and the application layer protocol HTTP. But implementing the TCP and HTTP protocols is obviously an undue requirement for small devices. In order to allow small devices to access the internet, the CoAP protocol was designed. CoAP is an application layer protocol that runs on top of UDP rather than TCP as HTTP does. The CoAP protocol is very compact, with the smallest packet being only 4 bytes.
The controlled end comprises a wireless/wired network communication module and a protocol converter; the wireless/wired network communication module is connected with the protocol converter and used for sending the wireless signal from the cloud server to the protocol converter; the protocol converter is provided with a communication interface; the communication interface is connected to an elevator call and registration device for calling an elevator and floor registration control.
The input reservation signal on the mobile terminal APP comprises reservation time, floor information and arrival floor information, wherein the reservation time is the time when a passenger expects to arrive at the elevator, the floor information is the time when the passenger starts to take the elevator, and the arrival floor information is the floor which the passenger wants to arrive at. The cloud server receives the reservation signal from the mobile terminal, and the elevator which is most matched with the information of the elevator taking person is found in the shortest time through interaction with all the hall calling boards and the car control panel.
The cloud server principle is described briefly as follows:
(1) searching all landing calling boards in the area where the mobile terminal is located, deciding the most appropriate elevator and landing calling board by reading the elevator running information, and sending a registration signal to the landing calling board after a preset time;
(2) the hall call board feeds the registration information back to the cloud server;
(3) the cloud server sends the registration information to the mobile terminal and distributes the predicted arrival time;
(4) when the car arrives, the calling board outside the floor station feeds registration information back to the mobile terminal through the cloud server to prompt the car to enter;
(5) the cloud server sends the destination floor information to the car control panel of the corresponding elevator to register the destination floor, so that the elevator can move to the corresponding floor within the specified time.
The cloud server gives the most appropriate decision consideration for several factors as follows: the position of the mobile terminal, the position of each elevator, the distance between each elevator car and the floor of the call signal, the running direction of the elevator and the instruction registration allocation condition.
PLC is adopted in elevator control, automatic control of elevator operation is realized by software, and reliability is greatly improved. Most relays are removed, the control system is simple in structure, and external circuits are simplified. The PLC can realize various complex control systems, and conveniently increase or change control functions. PLC can carry out fault automatic detection and alarm display, improves the operation security to easy access. The elevator dispatching system is used for group control dispatching and management and improves the operation efficiency of the elevator. The control scheme is changed without changing hardware wiring.
