The equipment of the invention has unique equipment ID after leaving factory and has the function of surfing the Internet. The user indicates the specific use of the user to the equipment provider, and the equipment provider records the equipment ID and the client information in a third-party server without direct operation of the user. When the equipment is on the internet, the information about the client in the network server is automatically inquired or screened, and cloud access, message filtering and extraction are automatically carried out. And when information needs to be changed at the later stage, the equipment provider directly changes the information in the third-party server.
For example, in the loan transaction process of a third-party financial institution, the salesperson records the user requirement, and the equipment automatically accesses the server information required by the user.
The realization process of the invention is as follows:
(1) after the device is plugged into a battery and powered on, the WiFi chip U1 starts to work by supplying power through an external power supply circuit and the boost chip U3, and initial WIFI is provided. When the WIFI password input device is used for the first time, a user needs to connect initial WIFI provided by equipment through a mobile phone, and then inputs a user name and a password of the WIFI used by the customer, for example, if the equipment is set to be connected with family WIFI, the family WIFI name and the password need to be input. And completing the equipment network configuration.
(2) The specific working process is as follows:
① when the work is manual, a user can press a key on the shell, the key is connected with the main control chip U2, the main control chip U2 accesses the family WIFI network to surf the internet by waking up the WIFI chip U1, the WIFI chip U1 analyzes the network information after receiving the network information on the internet and transmits the network information to the main control chip U2 through a serial port, and the main control chip U2 receives the analyzed data to perform color lamp flicker control, so that the whole work is completed;
② when working automatically, only the initial mode is different from the manual mode, the main control chip U2 automatically wakes up the WIFI chip U1 at regular time for subsequent work, and wake up after pressing the substitute key, the other circuits have the same realization principle, and the description is omitted here.
When the device works normally, the device actively accesses cloud data through an HTTP protocol at regular time in a mode of accessing a server website, and controls the colored lamps to emit changeable light through the content returned by the cloud data, so that the effect of the message-transmitting indicator light is achieved. For example, the address link sent by the cloud message subscription indicator lamp is:
http://dshmg.co/9430288？bat＝100&clicks＝150&clicks＝151&clicks＝152
9430288 in the address link is the unique ID number of the device, and the server can perform network data interaction with the device through the ID, and the whole process follows the HTTP protocol. The control instruction received by the equipment is as follows:
{"act":"true","seqrep":"0","allrep":"0","blink":[{"col":"FF0000","rep":"0","on":"50","off":"50"},{"col":"FF7C00","rep":"0","on":"50","off":"50"},{"col":"FFFF00","rep":"0","on":"50","off":"50"},{"col":"7FFF00","rep":"0","on":"50","off":"50"},{"col":"00FF00","rep":"0","on":"50","off":"50"},{"col":"00FF7F","rep":"0","on":"50","off":"50"},{"col":"00FFFF","rep":"0","on":"50","off":"50"},{"col":"007FFF","rep":"0","on":"50","off":"50"},{"col":"0000FF","rep":"0","on":"50","off":"50"},{"col":"7F00FF","rep":"0","on":"50","off":"50"},{"col":"FF00FF","rep":"0","on":"50","off":"50"},{"col":"FF007F","rep":"0","on":"50","off":"50"},{"col":"FFFFFF","rep":"0","on":"50","off":"50"}],"delay":"1"}
in the data returned by the server in the HTTP network protocol: the act expresses whether the flashing behavior is adopted, true is yes, and other values are no; seqrep and allrep are the number of repetitions of the flashing sequence blink and all times; blink represents the content of the flashing sequence. The concrete contents are as follows: col represents the flashing light color, and the value is the value of the RGB color table; rep is the number of repeated blinks; on is the lighting time in the rule of flashing the light, and the unit is 10 milliseconds; off is the off duration in the flashing law, and the unit is 10 milliseconds; delay is the interval duration of the next flashing when the flashing of the lamp is finished once, and is unit of second.
When the equipment with the ID number receives HTTP protocol data returned from the network, the data content is analyzed, and the light flickers after the flickering mode of the colored lamps is obtained. The cloud message subscription indicator lamp receives the return data, and specifies the flashing modes of the RGB colored lamps according to the return data, including flashing color, rule, time and the like. After the WiFi module receives the data, the data returned by the server are translated into software logic which can be identified by the main controller through the UART serial port, the main controller controls the level of the RGB three-color LED lamp or PWM waveform control through controlling the GPIO, and then flashing signals which can be identified by a user are made, and indication of specific signals is achieved.
After the light flickers (or the user manually presses the key and the like), the voltage boosting chip U3 turns off the main control chip U2 to enter a sleep energy-saving mode, and at the moment, the power consumption is in the microampere level until the next key press or the automatic awakening time is reached.
In addition, the cloud data can be actively acquired by pressing the first key S2 connected with the main control chip U2, when the function of actively acquiring the cloud data at regular time is used, great convenience is brought to a user, and the user does not need to manually inquire the information concerned by the user through a mobile phone or a computer or other internet access equipment which wastes time and labor.
The whole equipment has low power consumption and can be used for a long time; when the method does not occupy the time for manually searching the information by the user, the user can conveniently obtain the information concerned by the user like watching the pocket watch to obtain the time; the device transmits information in a mode of analyzing network data and carrying out color lamp flickering. The invention has the characteristics of energy saving, time saving, intuition and accuracy.
It will be understood that modifications and variations can be made by persons skilled in the art in light of the above teachings and all such modifications and variations are intended to be included within the scope of the invention as defined in the appended claims.
The invention is described above with reference to the accompanying drawings, which are illustrative, and it is obvious that the implementation of the invention is not limited in the above manner, and it is within the scope of the invention to adopt various modifications of the inventive method concept and technical solution, or to apply the inventive concept and technical solution to other fields without modification.
