Abstract
The invention provides an analog quantity input controller for the Internet of Things. The input controller comprises a controller shell, a single integrated circuit chip and a network interface. The single integrated circuit chip is composed of a power circuit, a CPU, a memorizer, an analog-digital/digital-analog conversion circuit and an analog quantity signal input circuit. The single integrated circuit chip is in communication with a monitoring host of the Internet of Things through the network interface. The analog quantity input controller of the Internet of Things has the advantages that based on an advanced chip production technology, consistency, stability and reliability of chip controller products are ensured; with the industrial TCP/IP protocol, the control speed can reach 10/100/1000 MB per second and is far higher than the speed of a traditional bus controller, wherein the speed of the traditional bus controller is several MB per second. Thus, the problems of the speed, the stability and the reliability of the most nuclear controller of a control system are solved. The size of the controller can be made to be smaller, the development cycle is short, and the cost of the single controller can be less.
Description
Technical field
The present invention relates to technology of Internet of things field, relate to particularly the comprehensive monitoring management technology of Internet of Things.
Background technology
Need a large amount of Data Control in fields such as Industry Control, building comprehensive monitoring management, information security management, environmental protection management, energy management, city management at present.Data Control comprises analog input control, digital quantity input control.Wherein analog input control comprises voltage or current signal input, as 4-20mA, and 0-5V, 0-20mA, 1-5V, the voltage of all sizes such as 0-10V or current signal input, by carrying out system control to network system input analog amount signal, sort controller is called analog input controller.At present, this analog input controller generally comprises controller housing, multiple discrete component or multiple integrated circuit (IC) chip and field bus control system, this by field bus control system, adopt many discrete components or the mode of multiple design of integrated circuit on circuit board to have following problem:
1. the technique of product is difficult to guarantee, owing to relating to many discrete components or multiple integrated circuit (IC) chip.The quality of each device is the steady quality reliability of the whole product of impact directly;
2. product development cycle is long, and cost is higher;
3. adopt field bus control system technology, picking rate is slow, is generally no more than as 2MB/S.
Summary of the invention
For this reason, technical matters to be solved by this invention is: provide a kind of analog input controller for Internet of Things, to overcome the shortcoming of above-mentioned prior art.
So, the invention provides following technical scheme:
A kind of analog input controller for Internet of Things, described input control device comprises controller housing, single integrated circuit chip and network interface, described single integrated circuit chip is made up of power circuit, CPU, storer, modulus/D/A converting circuit and analog signals input circuit, and described single integrated circuit chip is by the monitoring host computer communication connection of described network interface and Internet of Things.
Preferably, described network interface is TCP/IP network interface.
Analog input controller of the present invention adopts the network interface of industrial ICP/IP protocol, realize the function of analog input Internet of Things controller with one single chip, like this by the consistent reliability of advanced chip production technique, assurance chip controller product, adopt industrial ICP/IP protocol to improve control rate and can reach 10/100/1000MB/S, the speed of several MB/S of ultra-traditional bus controller far away.Speed and the reliability problem of the most crucial controller of control system have solved like this, and the volume of controller can do littlely, and the construction cycle is fast, and single cost can be less.

Fig. 1 is that the structure of embodiment analog input controller connects block diagram.
Embodiment
Below, describe the present invention by reference to the accompanying drawings.
The present embodiment connects block diagram referring to accompanying drawing 1 for the structure of the analog input controller of Internet of Things, comprise controller housing (not shown), single integrated circuit chip 1 and TCP/IP network interface 2, single integrated circuit chip 1 is made up of power circuit 3, CPU4, storer 5, modulus/D/A converting circuit 6 and analog signals input circuit 7, and single integrated circuit chip 1 communicates to connect by TCP/IP network interface 2 and the monitoring host computer 8 of Internet of Things.
Its principle of work is: the simulating signal of field data is inputted via simulated measurement input circuit 7, be converted to digital signal through modulus/D/A converting circuit 6, pass to CPU4 processing unit, CPU4 is kept at storer 5 after treatment data-signal, CPU4 passes to TCP/IP network interface 2 data simultaneously, by TCP/IP network interface 2 and monitoring host computer 8 exchange messages, by the analog signals of monitoring host computer 8 monitoring site data.
The analog input controller of the present embodiment adopts the network interface of industrial ICP/IP protocol, realize the function of analog input Internet of Things controller with one single chip, like this by the consistent reliability of advanced chip production technique, assurance chip controller product, adopt industrial ICP/IP protocol to improve control rate and can reach 10/100/1000MB/S, the speed of several MB/S of ultra-traditional bus controller far away.Speed and the reliability problem of the most crucial controller of control system have solved like this, and the volume of controller can do littlely, and the construction cycle is fast, and single cost can be less.
The foregoing is only preferred embodiment of the present invention, in order to limit the present invention, within the spirit and principles in the present invention not all, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
