Detailed ways

Below in conjunction with accompanying drawing, further illustrate the specific embodiment of the present utility model.

As shown in FIG. 1 , the utility model discloses an alarm device for a large-span communication room, which includes: a main control module 1 , a sensor 2 , an alarm device 3 , a communication module 4 and a mobile communication device 5 .

As shown in Fig. 2 in conjunction with Fig. 1, a specific embodiment of an alarm device for a large-span communication room is illustrated.

The sensor 2 is used to detect the situation of the large-span communication room in real time and output sensing signals. In this embodiment, the sensor 2 uses an infrared sensor to send a sensing signal to the follow-up equipment in real time. When someone enters the large-span communication room to commit theft, the infrared sensor collects the electromagnetic radiation of the person and outputs the sensing signal.

The main control module 1 is used to receive the sensing signal output by the sensor 2 in real time, and analyze the sensing signal. When the analysis shows that there is a theft against the large-span communication room, it will send an alarm signal and send the alarm information to Remote managers.

As shown in FIG. 3 , in this embodiment, the main control module 1 adopts a single-chip microcomputer, the model of which is STC89C52. K1, K2, K3, and K4 are four keys, which are setting key, up key, down key and query key respectively. L2 is an alarm LED light-emitting tube. P0.0-P0.7 are LCD data lines, P2.5-P2.7 are LCD control lines. The main control module 1 is also connected with a clock circuit, and the clock circuit is used to calculate the current time. In this embodiment, the clock circuit adopts a DS1302 clock circuit. The main control module 1 is also connected with an EEPROM storage circuit, 2402_SCL and 2402_SDA are the communication pins of the storage circuit, and the storage circuit is used for automatic storage of the alarm time, and can query and display the last alarm time. In this embodiment, the storage circuit adopts an external memory chip AT24C04, the chip is an IIC interface chip, which communicates through the two-wire interface of the clock line and the data line.

Alarm device 3 adopts buzzer alarm device. When someone commits theft, the alarm device 3 receives the alarm signal sent by the main control module 1 and gives a voice alarm.

In this embodiment, the sensor 2, the main control module 1, and the alarm device 3 can be integrated on a single-chip microcomputer development board, so as to improve the integration degree of the whole system.

The communication module 4 adopts a global system for mobile communication short message module (GSM module). The communication module 4 is used for receiving the alarm signal sent by the main control module 1 and performing remote transmission.

The communication module 4 trigger mode is divided into two kinds: TEXT MODE and PDU MODE, Text Mode sends and receives short message code is simple, it is very easy to realize, but the biggest shortcoming is that can not send and receive Chinese short message, but the realization of this utility model large span communication room alarm device It has no effect, PDU Mode not only supports Chinese text messages, but also can send English text messages, but the sending and receiving code is too long and complicated, and it is not convenient to compile the code. For the utility model, it is only required that the device can send a signal when theft occurs, so Text Mode is preferred.

In this embodiment, the communication module 4 can adopt the following three types of GSM modules: TC35i, M22, and JB35GD.

TC35i consists of 6 parts including power supply module (ASIC), flash memory, ZIF connector, and antenna interface. As the core baseband processor of TC35i, it mainly deals with voice and data signals in GSM terminals, and covers all analog and digital functions in cellular radio frequency equipment.

M22 is a GPRS module with built-in TCP/IP over PPP launched by BENQ, the price is relatively cheap. In terms of design structure, it uses a slot instead of a cable, so that it can be placed in the air without occupying the PCB area, and the SIM card slot and other chips and circuits can be placed under it. Complete GPRS dial-up, PPP connection, TCP/IP application through AT commands, which is more convenient to use. However, its shortcomings are also obvious: the stability is not enough, and the microphone and earpiece interface need more troublesome filter circuits. Part of TCP/IP has limited functions, and can only realize standard TCP/UDP communication. It can only be used as a client, and does not support listening, so it cannot be used as a server. However, even if the interception function module can be provided, it cannot be used in most GPRS environments, because usually, the IP address assigned by China Mobile to GPRS end users is not the public network IP on the Internet, but the mobile internal address, accessed through NAT INTERNET. In this way, public network IP users cannot connect to mobile internal IP.

JB35GD SMS module is a control system composed of GSM module and single chip microcomputer. GSM or CDMA mobile phone module is mainly used to establish a wireless channel, and receive and send short messages. The single-chip microcomputer system is used to control the mobile phone module, and interpret and execute the received short message information. The single-chip microcomputer control board adopts dual CPU mode, so that the system can handle multiple tasks at the same time, and the watchdog circuit with independent clock is used to prevent the software from crashing. MT8870 is responsible for dual audio decoding, completes DTMF call remote control, MAX232 completes RS232 communication with computer, CD4094 completes output serial to parallel eight-way isolated driving relay.

BenQ is the cheapest GPRS module with TCP/IP protocol stack. Siemens is the first choice for high-reliability applications in industry and vehicles. For general industrial and vehicle applications that are more cost-sensitive, Wavecom can be used. It is recommended to use BenQ for general environment and highly cost sensitive. In addition, it should be clear: When choosing GPRS data communication, you should pay attention to whether you need to embed the TCP/IP protocol stack, which also affects the choice of brand and model. GPRS external Modem is generally only GPRS module + SIM card + power conversion + RS232 interface and simple It is best to use modules directly for embedded applications, and for desktop applications, you can consider using a finished product "cat", and the original import price is only more than 1,000. When selecting modules for embedded applications, if only SMS and voice are used, Siemens TC35i is a good choice. If GPRS data communication is used, it is best to choose a module with a protocol stack. For low-end applications, you can choose BenQ modules such as M22.

For the requirements of the present invention, it is only necessary that the device can send a short message to notify the maintenance personnel at the first time when receiving the intrusion signal, so TC35i is preferred in this embodiment.

The mobile communication device 5 can adopt a mobile phone to receive the alarm short message remotely transmitted by the communication module 4, and inform the management personnel, and the management personnel can rush to the scene for real-time maintenance in time.

The alarm device in the large-span communication room also includes a power module, which provides continuous and stable DC +5V power supply to the sensor 2, the main control module 1, the alarm device 3, and the communication module 4 respectively, which meets the load requirements. The power module can adopt solar panel, wind generator or mobile power supply.

Although the mobile power supply has advantages in economy and portability, its working mode makes it necessary to recharge frequently, and the output voltage and current of the mobile power supply will become smaller with the length of use, so that it can be used The time is shortened, and there are certain defects in the continuity and stability of work. Since the solar panel is equipped with a battery, it can be recharged by itself, and the maintenance cost and labor cost in the later period are relatively small, and the stability is good.

Limited by the conditions of the large-scale communication room, solar panels are more convenient to install than fans; and remote areas have sufficient sunshine, and the efficiency of solar power is higher in terms of energy conversion.

Therefore, the power module in this embodiment preferably adopts a solar panel.

Although the content of the present invention has been described in detail through the above preferred embodiments, it should be recognized that the above description should not be considered as a limitation of the present invention. Various modifications and substitutions of the present utility model will be obvious to those skilled in the art after reading the above content. Therefore, the protection scope of the present utility model should be defined by the appended claims.
