Abstract
The utility model provides an analog input controller used for 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 formed by a power supply circuit, a CPU, a memory, an analog-digital/digital-analog conversion circuit and an analog signal input circuit. The single integrated circuit chip is connected with a monitoring host of the Internet of things through the network interface in a communication connection mode. The input controller has the advantages that through an advanced chip production technology, consistent and stable reliability of a chip controller product is guaranteed; an industrial TCP/IP protocol is used so as to increase a control speed to 10/100/1000MB/S and the speed is a few MB/S faster than a speed of a traditional bus controller; a speed problem of a core controller of a control system and a stable reliability problem are solved; the size of the controller can be smaller, a development period is fast and cost of a single one is low.
Description
Technical field
The utility model relates to technology of Internet of things field, relates 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 ensure, 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.
Utility model content
For this reason, technical problem to be solved in the utility model is: provide a kind of analog input controller for Internet of Things, to overcome the shortcoming of above-mentioned prior art.
So the utility model 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 utility model 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, guarantee 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.
Brief description of the drawings
Fig. 1 is that the structure of embodiment analog input controller connects block diagram.
Embodiment
Below, by reference to the accompanying drawings the utility model is described in detail.
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, guarantee 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 utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
