Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
It will be understood that when an element is referred to as being "secured to" or "disposed on" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present.
In addition, it should be noted that the terms of orientation such as left, right, up, down, head and tail in the embodiments of the present invention are only relative concepts or reference to the normal use state of the product, and should not be considered as limiting. The following describes the present invention in detail with reference to specific embodiments.
the camera module and the main controller are in serial communication, and a serial command can require the module to intercept a video and then obtain a JPEG image.
The temperature measurement range of the non-contact MLX90614ESF infrared temperature measurement module is as follows: -70-380 ℃, resolution: 0.02 ℃, precision: plus or minus 0.5 ℃ and is communicated with the main controller by a serial port.
The sound and light alarm module is connected with the main controller by a serial port and can emit various sounds such as 'fingerprint identification failure', 'fingerprint identification success', 'illegal intrusion', 'high temperature alarm' and the like.
The safety light curtain sensor is connected with the main controller through a digital switch interface; the intelligent alarm device for high-voltage equipment overhaul further comprises a TF memory card, and the TF memory card is connected with the main controller through a data control bus. The number of the safety light curtain sensors can be set to be multiple according to actual needs; the number of the safety light curtain sensors corresponds to the number of the digital quantity switch interfaces in the main controller.
Specifically, an Arduino UNO R3 development board was used as the master controller, and Arduino UNO R3 is an ATmega 328P-based microcontroller board. It has 14 digital input/output pins (6 of which can be used as PWM outputs), 6 analog inputs, a 16MHz crystal clock, a USB connection, a power jack, an ICSP connector, and a reset button. The power supply, the program downloading and the data communication can be realized only by connecting the USB data wire with the computer. The safety light curtain sensor NA2-N8 emits infrared light through the emitting end, and forms a safety grating with the receiving end. When an external irrelevant person enters the intelligent security system without fingerprint identification and authentication, the safety light curtain sensor outputs a switching value signal to the main controller. The main controller drives the sound-light alarm module to send out an alarm signal.
In the embodiment, the AS608 fingerprint module is used for fingerprint authentication, and the first pass after the maintainer passes the fingerprint authentication will not trigger an alarm signal; a TTL camera based on a middle satellite micro VC0706 chip is adopted to communicate with an Arduino UNO R3 main controller through a serial port. And when fingerprint authentication is carried out, the main controller controls the camera to shoot and stores the shot picture to the TF memory card.
When the alarm signal is detected, the main controller sends the alarm information to the GPRS module through the serial port, and the 4G mobile phone card is arranged in the GPRS module and can send the alarm information to a set mobile phone in the form of short messages. The non-contact MLX90614ESF infrared temperature measurement module is adopted to detect the inflammable area of the repaired equipment, and after abnormal high temperature exceeding 90 degrees is detected, an audible and visual alarm signal is sent out and sent to a set mobile phone in the form of short message.
Specifically, by adopting a 32G high-speed TF memory card, historical data within 3 months can be saved; the high-energy lithium battery with 5000mAH is adopted, so that the continuous working of the equipment can be ensured for more than 48 hours, and the external equipment can charge the lithium battery through the external charging interface.
When the intelligent alarm device is used on site, the intelligent alarm device is fixed on the top of one of the safety light curtain sensors through a mounting bracket, and the intelligent alarm device is particularly shown in a reference figure 2.
Referring to fig. 4, the working flow of the intelligent alarm device is as follows: after the machine is started, the safety light curtain sensor is started, a maintainer needs to perform fingerprint identification at the moment, the acousto-optic alarm module gives out sound of 'successful fingerprint identification' after the identification is successful, and otherwise, sound of 'failed fingerprint identification' is given out. The first entry will not alarm after the fingerprint identification is successful. The maintainer carries out fingerprint identification in proper order and gets into, and fingerprint identification camera all can shoot at every turn to the personnel identity and the state that the record got into.
After the safety light curtain sensor detects the illegal intrusion, the sound and light alarm module sends out an illegal intrusion alarm sound and sends alarm information to the mobile phone of the responsible person in a short message mode. After the infrared temperature measurement module detects that the temperature of the high-voltage equipment exceeds the limit, a warning of high-temperature alarm is sent out.
Finally, the above embodiments are only used for illustrating the technical solutions of the present invention and not for limiting, and other modifications or equivalent replacements made by the technical solutions of the present invention by those of ordinary skill in the art should be covered within the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solutions of the present invention.
