Gas meter of today has automatic charging function, an Every household has an ammeter card, and expense is given administrative authority by user, and administrative authority will purchase in tolerance write IC-card, and information in IC-card inputs in intelligent gas meter by user, and intelligent gas meter is automatic valve opening air feed just.In the process of user's gas, in intelligent gas meter, micro computer is examined and made cuts residue tolerance automatically, and tolerance of purchasing is used up, and intelligent gas meter valve-closing is died, and user need purchase gas again can valve opening air feed again.But existing gas meter, owing to lacking corresponding mechanism for monitoring, easily suffers the damage of lawless person, affect the normal use of ammeter.Along with the development of electronic technology and the communication technology, how wireless network and Ethernet are applied to gas meter monitoring field, utilize real-time performance to the data of gas meter, flow meter and transmission of video, data exchange, thus improve confidentiality, the reliability of gas meter, avoid the situation occurring stealing gas and dismantle.
Utility model content
The utility model overcomes the deficiencies in the prior art; gas meter monitoring terminal is provided, utilizes wireless network and Ethernet to realize gas meter, flow meter data and transmission of video, and be provided with mechanism for monitoring and protection mechanism; improve the confidentiality of gas meter, reliability, avoid the situation occurring stealing gas and dismantle.
For solving above-mentioned technical matters, the utility model is by the following technical solutions: gas meter monitoring terminal, comprise ARM9 processor, Zigbee module, ethernet module, I/O interface, audio coder, LCD display and UART Universal Asynchronous Receive/generating means, described Zigbee module, ethernet module, I/O interface, audio coder, LCD display and UART Universal Asynchronous Receive/generating means are all connected on ARM9 processor, and ARM9 processor also connects camera, WatchDog Timer, DDR sdram memory and FLASH flash memory; Described audio coder also connects loudspeaker.Ethernet module wherein carries out data communication with the speed of 10M/100M and to be connected with other terminal and to communicate, thus it is mutual various information to be carried out high-speed data.UART Universal Asynchronous Receive/generating means is connected with gas meter, flow meter, then collection gas meter, flow meter flow information passes to ARM9 processor and processes, by DDR sdram memory and FLASH flash memory, combustion gas information is stored, and information is shown by LCD display, also carry out telemanagement to other terminal the data information transfer of collection by ethernet module simultaneously.The wireless data that the Zigbee module arranged in addition also realizes between other wireless data terminal by wireless network communication technique is mutual, and carries out process transmission of information by ARM9 processor.Transmission between data is all transmitted by network, and transmission speed is faster, and data transmission procedure is also more concealed, improves the confidentiality of gas meter.If occur, other lawless person carries out surreptitiously gas or dismounting to gas meter and destroys the behavior of gas meter, and ARM9 processor receives this information will feed back to audio coder, thus makes loudspeaker send chimes of doom prompting external staff.Camera also can externally be made a video recording in addition, shooting information is transferred out on other remote terminal by ethernet module or Zigbee module, thus finds fast, avoids the situation of surreptitiously gas and dismantle, improves gas meter reliability of operation.The I/O interface simultaneously arranged also can insert other exterior terminal, realizes data transmission.The setting of WatchDog Timer, provides independently protection system to processor, and when system malfunctions, after optional time out period, house dog will respond with RESET signal; Also can reset to processor when program crashes, improve the reliability of this terminal.
Described Zigbee module is also connected by wireless communication with concentrator.By wireless network transmissions data more convenient and quicker, eliminate a large amount of wirings.
Described UART Universal Asynchronous Receive/generating means is connected with gas meter, flow meter.
Described ARM9 processor also connects touch-screen.The setting of touch-screen is then convenient to be arranged terminal.
The model of described ARM9 processor is AM1808 ARM926EJ-S.This processor have employed more transistor, and increase clock frequency and reduce instruction execution cycle, can reach more than twice in the processing power of ARM7 processor, treatment effeciency is higher, and performance is more superior.
The model of described ethernet module is 140NOE77101.
Compared with prior art, the beneficial effects of the utility model are:
1, this terminal is mutual with the wireless data between other wireless data terminal by arranging the realization of igbee module, various data message also can be carried out remote transmission by the Ethernet of 10M/100M, data transmission procedure is also more hidden and quick, confidentiality, gas-robbery resistence and Anti-dismantling ability are all improved.
2, the setting of camera can externally be made a video recording, shooting information is transferred out on other remote terminal by ethernet module or Zigbee module, if occur simultaneously, other lawless person carries out surreptitiously gas or dismounting to gas meter and destroys the behavior of gas meter, ARM9 processor receives this information will feed back to audio coder, thus make loudspeaker send chimes of doom prompting external staff thus find fast, the situation of surreptitiously gas and dismantle avoided by double insurance, improves gas meter reliability of operation.
3, the I/O interface arranged also can insert other exterior terminal, realizes data transmission.
4, the setting of WatchDog Timer, provides independently protection system to processor, and when system malfunctions, after optional time out period, house dog will respond with RESET signal; Also can reset to processor when program crashes, improve the reliability of this terminal.
