本发明涉及一种主要用于智能家居安防系统中使用的门磁传感器或探测器，特别涉及双向无线智能门磁探测器。The invention relates to a door magnetic sensor or detector mainly used in a smart home security system, in particular to a two-way wireless smart door magnetic detector.
背景技术Background technique
在智能家居门禁系统中,门磁探测器是用来探测门、窗、抽屉等是否被非法打开或移动的防盗报警装置，或是安装于门与门套上，开关安装于屋内，配合自动闭门器使用的报警装置，是办公场所、工作场所、家庭监控非法行为，保障安全的第一道防线。门磁开关通常的作用是负责门磁通电否，通电带磁(闭门)，断电消磁(开门)，门磁安装于门与门套上，开关安装于屋内，配合自动闭门器使用。报警装置一般可分为门磁开关、门磁传感器或探测器、门磁报警器三大部分。门磁探测器分为有线门磁和无线门磁，有线门磁或无线门磁传感器是感应门窗开合，发出有线常闭/常开开关信号的装置。采用有线连接方式的磁探测器，其不足之处在于在已经装修完毕建筑体中安装不是很方便，出现故障也不好检测。无线门磁传感器用来监控门的开关状态，当门不管何种原因被打开后，无线门磁传感器立即发射特定的无线电波，远距离向主机报警。无线门磁由无线发射器和磁块两部分组成。在无线发射模块有两个箭头处有一个“干簧管S2”的元器件，当磁体与干簧管S2的距离保持在1.5厘米内时，干簧管S2处于断开状态，一旦磁体与干簧管S2分离的距离超过1.5厘米时，干簧管S2就会闭合，造成短路，报警指示灯亮的同时向主机发射报警信号。无线门磁的无线报警信号在开阔地能传输200米，在一般住宅中能传输20米，和周围的环境密切相关。无线门磁一般采用省电设计，当门关闭时它不发射无线电信号，此时耗电只有几个微安，当门被打开的瞬间，立即发射1秒左右的无线报警信号，然后自行停止，这时就算门一直打开也不会再发射了，这是为了防止发射机连续发射造成内部电池电量耗尽而影响报警，无线门磁还设计有电池低电压检测电路，当电池的电压低于8伏时，下方的LP发光二极管就会点亮，这时需要立即更换A23报警器专用电池，否则会影响报警的可靠性。无线门磁传感器一般安装在门内侧的上方，它由两部分组成:较小的部件为永磁体，内部有一块永久磁铁，用来产生恒定的磁场，较大的是无门磁主体，它内部有一个常开型的干簧管S2，当永磁体和干簧管S2靠得很近时(小于5毫米)，无线门磁传感器处于工作守候状态，当永磁体离开干簧管S2一定距离后，无线门磁传感器立即发射包含地址编码和自身识别码(也就是数据码)的315MHZ的高频无线电信号，接收板就是通过识别这个无线电信号的地址码来判断是否是同一个报警系统的，然后根据自身识别码(也就是数据码)，确定是哪一个无线门磁报警。In the smart home access control system, the door magnetic detector is an anti-theft alarm device used to detect whether doors, windows, drawers, etc. The alarm device used by the door switch is the first line of defense for monitoring illegal activities in offices, workplaces, and homes to ensure safety. The usual function of the door magnetic switch is to control whether the door magnet is energized or not, when it is energized, it will be magnetized (close the door), and when it is powered off, it will demagnetize (open the door). Alarm devices can generally be divided into three parts: door magnetic switch, door magnetic sensor or detector, and door magnetic alarm. The door sensor is divided into wired door sensor and wireless door sensor. The wired door sensor or wireless door sensor is a device that senses the opening and closing of doors and windows and sends a wired normally closed/normally open switch signal. The disadvantage of magnetic detectors using wired connections is that it is not very convenient to install in a building that has been decorated, and it is not easy to detect when a fault occurs. The wireless door magnetic sensor is used to monitor the opening and closing status of the door. When the door is opened for any reason, the wireless door magnetic sensor immediately emits a specific radio wave and sends an alarm to the host remotely. The wireless door sensor is composed of two parts: a wireless transmitter and a magnetic block. There is a "reed switch S2" component at the two arrows of the wireless transmitting module. When the distance between the magnet and the reed switch S2 is kept within 1.5 cm, the reed switch S2 is in a disconnected state. When the separated distance of the reed switch S2 exceeds 1.5 centimeters, the reed switch S2 will be closed, causing a short circuit, and the alarm indicator light is on to transmit an alarm signal to the host. The wireless alarm signal of the wireless door sensor can transmit 200 meters in open areas and 20 meters in ordinary houses, which is closely related to the surrounding environment. The wireless door sensor generally adopts a power-saving design. When the door is closed, it does not emit radio signals. At this time, the power consumption is only a few microamperes. When the door is opened, it immediately emits a wireless alarm signal for about 1 second, and then stops automatically. At this time, even if the door is always open, it will not transmit again. This is to prevent the internal battery from being exhausted due to continuous transmission of the transmitter and affecting the alarm. The wireless door sensor is also designed with a battery low voltage detection circuit. When the battery voltage is lower than 8 When volts, the LP light-emitting diode below will light up. At this time, the special battery for the A23 alarm needs to be replaced immediately, otherwise the reliability of the alarm will be affected. The wireless door magnetic sensor is generally installed above the inner side of the door. It consists of two parts: the smaller part is a permanent magnet, and there is a permanent magnet inside to generate a constant magnetic field. The larger one is the main body without door magnet. There is a normally open reed switch S2. When the permanent magnet and the reed switch S2 are very close (less than 5mm), the wireless door magnetic sensor is in the working standby state. When the permanent magnet is away from the reed switch S2 for a certain distance , the wireless door magnetic sensor immediately transmits a 315MHZ high-frequency radio signal containing an address code and its own identification code (that is, a data code), and the receiving board judges whether it is the same alarm system by identifying the address code of the radio signal, and then According to its own identification code (that is, the data code), determine which wireless door magnetic alarm is.
目前，市面上使用的门磁探测器大多是单向的门磁传感器，单向门磁传感器只能检测打开状态，而不能检测关闭状态的信息。现有技术安装在门窗开启处，用来探测门窗的开启状态，通过Wi-Fi模块实现每开启一次均发出报警信号给主机，在门磁布防的情况下，主机将报警的门磁探测器，主要由电源模块、门磁感应开关模块、中央处理模块、射频调制发射模块和低电压检测模块组成或采用门磁设备，云服务器，手持终端，WIFI路由器组成的，这种无线智能门磁系统采用的中央处理模块的不足之处在于，中央处理模块采用ARM芯片成本高体积大、电路设计复杂，功耗大，电池只能支持几天。但都采用高成本的ARM芯片来实现上述功能。At present, most of the door magnetic detectors used in the market are one-way door magnetic sensors, and the one-way door magnetic sensors can only detect the open state, but cannot detect the information of the closed state. The existing technology is installed at the opening of the door and window to detect the opening state of the door and window. Through the Wi-Fi module, an alarm signal is sent to the host every time it is opened. It is mainly composed of a power supply module, a door sensor switch module, a central processing module, a radio frequency modulation transmitter module and a low voltage detection module, or it is composed of a door sensor device, a cloud server, a handheld terminal, and a WIFI router. This wireless smart door sensor system uses The disadvantage of the central processing module is that the central processing module adopts an ARM chip with high cost, large volume, complex circuit design, high power consumption, and the battery can only support it for a few days. But all adopt the high-cost ARM chip to realize the above-mentioned functions.

参阅图2。在上述结构中，结合图1、图2进一步说明，双向无线智能门磁探测器主机在电路设计上，全采用低功耗器件，MCU外围电路都采用低功耗设计，与MCU的I/O相关的外围电路在上电后都为高电平，这就保证了产品上电后MCU能进入低功耗掉电模式。门磁传感器可以选用干簧管S2，主机上电后会进入低功耗掉电模式，产品进入低功耗掉电模式后，开门电路和关门电路的输出高电平并自动进入掉电模式，只要磁柱接近它在一定的距离内，簧管两个触点就会吸合在一起。See Figure 2. In the above structure, combined with Fig. 1 and Fig. 2, it is further explained that the circuit design of the two-way wireless intelligent magnetic door sensor host adopts low-power devices, and the peripheral circuits of the MCU adopt low-power designs, which are compatible with the I/O of the MCU. The relevant peripheral circuits are all high level after power-on, which ensures that the MCU can enter the low-power power-down mode after the product is powered on. The door magnetic sensor can use reed switch S2. After the host is powered on, it will enter the low-power power-down mode. After the product enters the low-power power-down mode, the output of the door-opening circuit and the door-closing circuit will output high levels and automatically enter the power-down mode. As long as the magnetic column approaches it within a certain distance, the two contacts of the reed switch will attract together.
在关门电路中，电连接在如图2所示，当关门时干簧管S2由断开状态变为闭合状态，二极管D3与晶体三极管Q2基极之间的接点C高电平信号通过Q2集电极接点D并联的电容C8 和接地电阻R20 产生瞬间放电，瞬间拉低电容C8与晶体三极管Q4基极之间接点E电位，Q4饱和导通，流过Q4 发射极电流经Q4 集电极串联电阻R18输入到晶体三极管Q6的基极，使Q6饱和导通，Q6集电极串联电阻R16间的接点F电位瞬间被拉低，产生一个下降沿单脉冲信号，具有通交流隔直流作用的电容C8接点E电位也被Q2回路上并联的电阻R14瞬间拉高，Q4和通过电阻R18连接的Q6被截止，Q6集电极电连接电阻R16间的接点F电位瞬间被R16拉高，这个单脉冲下降沿的脉冲宽度由上述隔离电容C8及其电连接的接地电阻R20参数决定。本实施例单脉冲下降沿的脉冲宽度设计为100us左右，这个下降沿脉冲信号接点F 输出端INT1传输至MCU的外部中断INT1，它使MCU产生关门中断信号，MCU被关门中断信号唤醒后，通过它的ADC管脚电连接的低电压检测电路对电池的电压进行电压采集，MCU从时钟电路获取关门时间，MCU再通过自身串口RS-232与WIFI模块的RS-232的电连，MCU将关门相关信息、电池电压信息、关门时间等信息经MCU的RS-232、WIFI模块和路由器发送到云端服务器进行存储记录，云端服务器根据用户的需求是否将相关信息通过网络、电话、微信、QQ、邮件、短信方式推送到用户手机或本地报警器，MCU信息发送结束后，MCU在无外部中断的情况下，MCU通过对WIFI模块供电控制电路的控制停止对WIFI模块和相关外围电路供电，再整机进入低功耗掉电模式。In the door-closing circuit, the electrical connection is as shown in Figure 2. When the door is closed, the reed switch S2 changes from the open state to the closed state, and the high-level signal at the junction C between the diode D3 and the base of the transistor Q2 passes through the Q2 collector. The capacitor C8 connected in parallel with the electrode contact D and the grounding resistor R20 produce instantaneous discharge, which instantly pulls down the potential of the contact E between the capacitor C8 and the base of the transistor Q4, Q4 is saturated and turned on, and the emitter current of Q4 flows through the series resistor R18 of the collector of Q4 Input to the base of the crystal transistor Q6, so that Q6 is saturated and turned on, the potential of the contact F between the series resistor R16 of the collector of Q6 is pulled down instantly, and a single pulse signal with a falling edge is generated, and the capacitor C8 contact E with the function of communicating AC and blocking DC The potential is also instantly pulled up by the resistor R14 connected in parallel on the Q2 circuit, Q4 and Q6 connected through the resistor R18 are cut off, and the potential of the contact F between the collector of Q6 connected to the resistor R16 is pulled up by R16 instantly, and the pulse of this single pulse falling edge The width is determined by the parameters of the isolation capacitor C8 and the grounding resistor R20 electrically connected thereto. The pulse width of the falling edge of the single pulse in this embodiment is designed to be about 100us. This falling edge pulse signal contact F output terminal INT1 is transmitted to the external interrupt INT1 of the MCU, which makes the MCU generate a door-closing interrupt signal. After the MCU is awakened by the door-closing interrupt signal, through Its ADC pins are electrically connected to the low-voltage detection circuit to collect the voltage of the battery, and the MCU obtains the closing time from the clock circuit, and then the MCU is electrically connected to the RS-232 of the WIFI module through its own serial port RS-232, and the MCU will close the door.

门磁传感器并联在开门电路和关门电路之间，开门时，作为门磁传感器的干簧管S2触点断开，断开信号被传输到关门电路，通过二极管D3传输到晶体三极管Q2的基极，使得并联在二极管D3与传输到晶体三极管Q2之间旁路接地电阻R1的接点C变为低电位，此时Q2饱和导通，Q2发射结与接地电阻R20之间的接点D点变为高电位，以及经接点D连接的电容C8，电容C8与晶体三极管Q4基极之间并联电阻R14接点E也变为高电位，此时晶体三极管Q4和经由串联电阻R18及其并联电容C10相连基极的晶体三极管Q6截止，Q6集电极与串联电阻R16接点F电路输出保持高电平不变。The door magnetic sensor is connected in parallel between the door opening circuit and the door closing circuit. When the door is opened, the contact of the reed switch S2 as the door magnetic sensor is disconnected, and the disconnection signal is transmitted to the door closing circuit, and then transmitted to the base of the transistor Q2 through the diode D3 , so that the junction C of the bypass grounding resistor R1 connected in parallel between the diode D3 and the transistor Q2 becomes a low potential, at this time, Q2 is saturated and turned on, and the junction D point between the emitter junction of Q2 and the grounding resistor R20 becomes high potential, and the capacitor C8 connected through the contact D, the parallel resistor R14 between the capacitor C8 and the base of the transistor Q4. The crystal triode Q6 cuts off, and the output of the contact F circuit between the collector of Q6 and the series resistor R16 remains high.
开门时, 开门电路由于干簧管S2由闭合状态进入断开状态，干簧管S2通过二极管D6与接地电阻R19之间的接点A为低电位，电连接在接点B与晶体三极管Q3基极之间的隔离电容C7通过并联电阻R19放电，电阻R19通过电连接在隔离电容C7与晶体三极管Q3基极之间的接点B电位瞬间被拉低，Q3饱和导通，流过Q3 发射极电流经Q3 集电极电连接的电阻R17传输到晶体三极管Q5的基极，Q5通过基极与发射极之间并联的接地电容C9饱和导通，Q5集电极与电阻R15之间的接点G电位瞬间拉低产生一个下降沿脉冲信号，此时，位接点A与接点B之间的隔离电容C7在通交流隔直流的作用下，接点B电位也被电连接在接点B与电源VCC之间的电阻R13瞬间拉高，使电连接在电阻R15、Q3、电阻R17和Q5回路上的Q3、Q5截止，Q5集电极与电阻R15之间的接点G电位瞬间又被电阻R15拉高。接点G产生的瞬间拉低的这个单脉冲下降沿的脉冲宽度由上述隔离电容C7及其电连接的接地电阻R19参数决定。本实施例单脉冲下降沿的脉冲宽度设计为100us左右。上述下降沿脉冲信号接点G 输出端INT2传输至MCU，使MCU产生开门中断信号，MCU被开门中断信号唤醒后，通过它的ADC管脚相连的低电压检测电路对电池的电压进行电压采集，从时钟电路获取开门时间，同时再通过自身串口RS-232相连的WIFI模块，将开门相关信息、电池电压信息、开门时间等信息经串口RS-232、WIFI模块和路由器发送到云端服务器进行存储记录。云端服务器根据用户的需求是否将相关信息通过网络、电话、微信、QQ、邮件和短信方式推送到用户手机或本地报警器。MCU信息发送结束后，在无外部中断的情况下，通过对WIFI模块供电控制电路的控制停止对WIFI模块的供电，进入低功耗掉电模式。When opening the door, the door opening circuit enters the disconnected state from the closed state of the reed switch S2, and the reed switch S2 is at a low potential through the contact A between the diode D6 and the grounding resistor R19, and is electrically connected between the contact B and the base of the transistor Q3. The isolation capacitor C7 between them is discharged through the parallel resistor R19, and the potential of the contact B between the isolation capacitor C7 and the base of the crystal transistor Q3 is pulled down instantaneously through the electrical connection of the resistor R19, Q3 is saturated and turned on, and the emitter current flows through Q3 through Q3 The resistor R17 electrically connected to the collector is transmitted to the base of the transistor Q5, Q5 is saturated and turned on through the grounding capacitor C9 connected in parallel between the base and the emitter, and the potential of the contact G between the collector of Q5 and the resistor R15 is pulled down instantaneously to generate A falling edge pulse signal, at this time, under the action of the isolation capacitor C7 between the contact point A and the contact point B, the potential of the contact point B is also pulled instantaneously by the resistor R13 electrically connected between the contact point B and the power supply VCC High, so that Q3 and Q5 electrically connected to the circuit of resistors R15, Q3, resistor R17 and Q5 are cut off, and the potential of the contact G between the collector of Q5 and resistor R15 is pulled up by resistor R15 in an instant. The pulse width of the falling edge of the single pulse that is momentarily pulled low by the contact G is determined by the parameters of the isolation capacitor C7 and the electrically connected grounding resistor R19. In this embodiment, the pulse width of the falling edge of the single pulse is designed to be about 100 us. The above-mentioned falling edge pulse signal contact G output terminal INT2 is transmitted to the MCU, so that the MCU generates a door-opening interrupt signal. After the MCU is awakened by the door-opening interrupt signal, the voltage of the battery is collected through the low-voltage detection circuit connected to its ADC pin. The clock circuit obtains the door opening time, and at the same time, through the WIFI module connected to its own serial port RS-232, the door opening related information, battery voltage information, door opening time and other information are sent to the cloud server through the serial port RS-232, WIFI module and router for storage and recording. The cloud server will push relevant information to the user's mobile phone or local alarm through the network, telephone, WeChat, QQ, email and SMS according to the user's needs. After the MCU information is sent, in the case of no external interruption, stop the power supply to the WIFI module through the control of the WIFI module power supply control circuit, and enter the low power consumption power-down mode.
