Description
Technical field
The present invention relates to a kind of switch, specifically be meant a kind of wireless remote switch.
Background technology
At present, in a lot of industries, all need to use remote switch control, generally speaking, what we adopted all is traditional data radio station, and the communication modes of this control mode mostly is single worker or half-duplex, and coverage is relevant with emissive power, the city is generally about 2km, the dead angle is also many, and message transmission rate is lower, and unreliable, operating cost is also than higher, the device transmission power consumption is big, communication distance is limited, is not durable and uses inadequately to make things convenient for.
Summary of the invention
Technical matters to be solved by this invention provides a kind of wireless remote switch, and is not only simple, light, and operation is convenient, and coverage is very wide, no dead angle, and the blind area is few, and communication distance is unrestricted.
The present invention solves the problems of the technologies described above the technical scheme that is adopted: a kind of wireless remote switch, by GPRS Module, and the antennal interface that links to each other with GPRS Module is formed, it is characterized in that, also include SIM card interface, CPU, and the power supply processing module that links to each other with CPU respectively, state indicating equipment, relay, switch detection, configuration interface, FLASH storer and SRAM storer, described GPRS Module also links to each other with CPU and power supply processing module respectively, and described SIM card interface then links to each other with GPRS Module.
In order to satisfy user's demand, the quantity of described relay is two or more.
Be complementary with the quantity of relay, the quantity that described switch detects is two or more.
On described power supply processing module, also be provided with a power interface.
In order to improve the reliability of this equipment of use, on described power supply processing module, also be provided with watchdog circuit, described watchdog circuit directly links to each other with CPU.
To sum up, the invention has the beneficial effects as follows:
(1) uses GPRS network, no communication distance restriction.
(2) switch with two or more detects and relay, so the passive node signal can be realized two-way real-time transmission.
(3) adopt the regular handset card, need not fixedly IP.
(4) built-in watchdog circuit, the reliability of raising equipment.
Description of drawings
Fig. 1 is the inner structure synoptic diagram of this wireless remote switch.
Embodiment
Below in conjunction with embodiment and accompanying drawing, to the detailed description further of the present invention's do, but embodiments of the present invention are not limited thereto.
Embodiment
As shown in Figure 1, this wireless remote switch, by GPRS Module, and the antennal interface that links to each other with GPRS Module is formed, its structure also includes the SIM card interface, CPU, and the power supply processing module that links to each other with CPU respectively, the state indicating equipment, relay, switch detects, configuration interface, FLASH storer and SRAM storer, described FLASH storer is a nonvolatile memory, simply say to be exactly that the storage data of the inside after the power down can not lost, described SRAM storer is a synchronous DRAM, it is exactly the internal memory that our PC or embedded system CPU need use, described GPRSModule also links to each other with CPU and power supply processing module respectively, and described SIM card interface then links to each other with GPRSModule.In order to satisfy user's demand, the quantity of described relay is two or more, be complementary with the quantity of relay, the quantity that described switch detects also is two or more, on described power supply processing module, also be provided with a power interface, in order to improve the reliability of this equipment of use, on described power supply processing module, also be provided with watchdog circuit, described watchdog circuit directly links to each other with CPU.
For maximum dirigibility and ease for use is provided, this wireless remote switch provides four kinds of mode of operations for the user: P2P SERVER pattern, P2P CLIENT pattern, APN SERVER pattern, APN CLIENT pattern.Main website works in the SERVER pattern, intercepts on a local port, waits for the connection of substation, and main website need not be provided with ID number of substation, and he accepts the connection of any legal substation.The substation works in the CLIENT pattern, and ID number of main website need be set, and the back that powers on, substation automatically can be set up TCP with main website and is connected, and occurs any unusually, and the substation assurance reconnects automatically, and is always online.The KEEPALIVE keepalive feature is all supported in main website and substation, can detect opposite end collapse (as sudden power), and the main website collapse is detected in the substation, can reconnect automatically, and main website detects any one substation collapse, discharges TCP SOCKET resource, waits for the connection of substation.When the user uses this equipment, only need to buy a regular handset card and get final product, be exactly to need configuration parameter then, most of parameter all adopts default configuration to get final product.The user needs " communication mode " of this equipment that will use as main website to be set to: P2P SERVER, need " communication mode " of this equipment that will use as the substation to be set to: P2P CLIENT, " main website device numbering " parameter has only the equipment that uses as the substation just to need to be provided with, and need to be set to this machine equipment numbering of the main website equipment of visit.All main websites are provided with identical access password with the substation, forbid the visit of other illegal substation.So, this wireless remote switch just can enter normal operating conditions.
As mentioned above, just can realize the present invention preferably.
