Embodiment
Understand essence of the present invention better for convenience of those skilled in the art, below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail.
As shown in Figure 1, a kind of remote serial port control module based on WiFi, comprise: be arranged on the WiFi module 1 on same circuit board 4, Voltage stabilizing module 2 and TTL serial ports and turn RS485 module 3, described WiFi module 1 is formed by ESP8266WIFI chip package, described Voltage stabilizing module 2 is powered for WiFi module 1 and TTL serial ports turn RS485 module 3, the TXD mouth that described TTL serial ports turns RS485 module 3 connects the RXD mouth of WiFi module 1, and the RXD mouth that described TTL serial ports turns RS485 module 3 connects the TXD mouth of WiFi module 1.
Wherein, WiFi module 1 is provided with antenna, described antenna is PCB antenna, IPEX interface antenna or the stamp hole interface antenna that ESP8266WIFI chip is formed in encapsulation process.For ease of application, be also circumscribed with flash memory in WiFi module 1, when WiFi module 1 ESP8266WIFI chip carry and as equipment in unique processor time directly start from external flash memory.
Be solidified with operation control program in described WiFi module 1, this program adopts the programming of LabVIEW (LaboratoryVirtualInstrumentEngineeringWorkbench) language to form.In other embodiments, the program in WiFi module by user according to oneself need carry out programming, be not limited to the present embodiment.
During the above-mentioned remote serial port control module of practical application, host computer and slave computer are installed a remote serial port control module respectively, for convenience of distinguishing, to be arranged on host computer being the first remote serial port control module below, to be arranged on slave computer is the second remote serial port control module.Specific works principle is: the control command that supervisory controller sends is transferred to corresponding WiFi module after turning RS485 module converts by the TTL serial ports of the first remote serial port control module, after corresponding WiFi resume module again in the mode of wireless signal to surrounding environment radiation; The second remote serial port control module on slave computer by the wireless signal in its WiFi module reception environment and through identification conversion after turn RS485 module transfer to slave computer controller by corresponding TTL serial ports, reach the object of Long-distance Control and long-range instruction.
In the present embodiment, described host computer, slave computer are all the commercial unit of band PLC control device.In other embodiments, described host computer is the intelligent terminal such as computer, mobile phone, described slave computer is the home appliance of tape controller, and remote serial port control module is connected with the I/O interface that can be carried by WiFi module between home appliance, is not limited to the present embodiment.
A kind of remote serial port control module based on WiFi that the present embodiment provides, adopt ESP8266WiFi chip as the core component of WiFi module 1, there is following beneficial effect: 1) plurality of wireless networks cipher mode can be supported, comprise: WEP64/WEP128/TKIP/CCMP (AES) WEP/WPA-PSK/WPA2-PSK etc., effectively fully ensure the safe transmission of user data.2) can network fast, the mode mainly through allocated channel number realizes quick networking.In common Wireless Networking process, first automatically can carry out single pass to current all channels, search for (or Adhoc) network of the object AP establishment preparing to connect.This module provides the parameter arranging working channel, under the condition of known object network place channel, can the working channel of direct designated module, thus reach the object accelerating networking speeds.3) function of binding object network B SSID address is supported in networking process.According to 802.11 agreement regulations, different wireless networks can have identical network name (namely SSID/ESSID), but the BSSID address that necessary correspondence one is unique.Illegal invasion person by setting up the method with the wireless network of identical SSID/ESSID, can make the STA in network be connected on illegal AP, thus causing divulging a secret of network.By the mode of BSSID address binding, STA can be prevented to be linked into illegal network, thus improve the security of wireless network.4) the radio roaming function based on 802.11 agreements is supported.Radio roaming refers to the coverage in order to expand a wireless network, the wireless network that one has identical SSID/ESSID is jointly created by multiple AP, each AP is used for covering different regions, the STA being linked into network can be the strongest according to the selection signal of present position AP access, and automatically to switch between different AP along with the movement of STA.
