Description

Window opens reminiscences

Technical field

The utility model relates to a kind of detection devices more particularly to a kind of window to open reminiscences.

Background technique

Since inside is more expensive instrument and equipment, the safety problem in laboratory is necessary in large-scale instrument laboratory Issues that need special attention, and the aisle window of large-scale experiment room be because fire-fighting requirements cannot be closed, and these to go to window necessary Close in real time, and these windows using general buckle lock construction can in the presence of very big security risk, especially with personnel In the case where excessive, the case where closing is forgotten after often will cause unlatching.

Whether therefore whether effective monitoring aisle window opens that it is very important, open for aisle window at present Detection device does not have substantially, can only be manually checked by administrator at present the monitoring of aisle window, and manually checks and exist Have and omits situation and check situation not in place.

Summary of the invention

The purpose of this utility model: providing one kind can accurately detect whether window is opened and the window of open state is opened Reminiscences.

To achieve the goals above, the technical solution of the utility model is:

A kind of window unlatching reminiscences, including window displacement sensor, open detection microcontroller, radio detection data pass Defeated device, open state reminding module and power supply, the window displacement sensor is connected to open detection microcontroller, described Open detection microcontroller is connected to radio detection data link, the open detection microcontroller by SPI digital interface Device is connected with open state reminding module and power supply respectively.

Above-mentioned window opens reminiscences, wherein the window displacement sensor uses capacitive displacement detecting chip PCAP02A。

Above-mentioned window opens reminiscences, wherein the open detection microcontroller uses at 16-Bit single-chip microcontroller Manage device R7F0C019L2.

Above-mentioned window opens reminiscences, wherein the radio detection data link is transmitted using radio frequency network Device A7102.The radio detection data link is using four line serial data interface of standard and the open detection micro-control Device processed carries out control and communication connection.

The across displacement between movable window that the utility model passes through detection relative motion, so that it is determined that window is to be in Open state, while monitoring side is sent for open state signal by wireless network, it monitors convenient for administrative staff, passes through simultaneously Blinking light demarcates window position, carries out effective shutoff operation to window convenient for administrator.

Specific embodiment

The embodiments of the present invention that the following is further explained with reference to the attached drawings.

Referring to Figure 1, shown in Fig. 2 and Fig. 3, a kind of window unlatching reminiscences, including window displacement sensor 1, unlatching inspection Micrometer controller 2, radio detection data link 3, open state reminding module 4 and power supply 5, the window displacement sensor 1 is connected to open detection microcontroller 2, and the open detection microcontroller 2 is connected to radio detection by SPI digital interface Data link 3, the open detection microcontroller 2 are connected with open state reminding module 4 and power supply 5 respectively.

Two fan movable windows to be monitored are separately mounted on be parallel to each other two tracks, and on two fan windows respectively Provided with one piece of relative displacement electrode slice, when window is closed completely, it is overlapped between two pieces of relative displacement electrode slices without opposite Area, at this point, the window displacement sensor 1 is connected respectively to two pieces of relative displacement electrode slice institutes by PC0 and PC1 interface Detection capacitance values are set to basic zero, and the open detection microcontroller 2 collects the capacitor base by SPI interface Plinth zero is simultaneously stored in inside internal FLASH memory.When window is turned on, due to being produced between two fan windows because of opening Raw relative displacement, the relative displacement electrode slice that will cause on two fan windows is parallel to each other staggeredly, thus in two blocks of relative displacement electricity Overlapping area is formed between pole piece, and the overlapping area can be bigger with window unlatching, overlapping area also can be bigger, at this time institute The window displacement sensor 1 stated can be with the change of overlapping area by capacitance values detected by two pieces of relative displacement electrode slices It synchronizing and becomes larger greatly, the open detection microcontroller 2 collects the capacitance values of corresponding variation by SPI interface, and By the way that the capacitor basis zero of the capacitance values of acquisition and storage inside to be compared, the capacitance values to determine acquisition are big In capacitor basis zero, and then determine that window is opened, it is in the open state, while the capacitance values by calculating acquisition are big In the multiple of capacitor basis zero, effectively to calibrate the degree numerical value of window unlatching, the capacitance values of acquisition are greater than capacitor base The multiple of plinth zero is bigger, represents window and opens bigger.Synchronous, open detection microcontroller 2 can be by window open state The data such as data and opening degree numerical value are transferred to management radio detection data link 3 in the form of radio frequency network Member monitoring side, with the degree for reminding administrator to notice that window is opened and opens, and radio detection data link 3 can be same Step control open state reminding module 4 starts interval flashing signal, in order to which administrator finds the position of unlatching window in time, and Carry out window shutoff operation.

After two fan movable windows of window are closed and are closed completely, open detection microcontroller 2 is displaced by window The capacitance that inductor 1 can collect between two pieces of relative displacement electrode slices reverts to capacitor basis zero, at this time open detection Microcontroller 2 can send administrator monitoring side by radio frequency network for window closed state, and synchronization can control closing shape State reminding module 4.

Preferably, the window displacement sensor 1 uses capacitive displacement detecting chip PCAP02A.

Preferably, the open detection microcontroller 2 uses 16-Bit processor of single chip computer R7F0C019L2.

Preferably, the radio detection data link 3 uses radio frequency network transmitter A7102.Described is wireless Detection data transmitter 3 is controlled and is led to the open detection microcontroller 2 using four line serial data interface of standard News connection.
