Embodiment 1
[0034] A GSM-based dual anti-theft gas meter reading system for smart homes. The gas meter reading system can realize the meter reading work of gas meters in a residential area or even multiple residential areas. The gas meter reading system includes a gas meter box 1, a collector, a GSM communication module and a controller. The gas meter box 1 is installed in the households of the community, and a gas meter 12 is arranged in each gas meter box 1, that is, one gas meter 12 for each household. One or more gas meters 12 are correspondingly provided with a collector, and the collector is used to collect gas information such as user information and gas consumption information recorded by the one or more gas meters 12 . One collector corresponds to one GSM communication module, and the collector transmits the gas information it collects to the GSM communication module through the GSM network. One or more GSM communication modules correspond to a controller, and the GSM communicat...
Embodiment 2
[0041] On the basis of Embodiment 1, the gas meter box 1 is vertically provided with a partition baffle 4, and the two sides of the partition board are respectively slid on the inner side of the gas meter box 1, and the partition baffle 4 separates the gas meter box 1 The inner cavity of the gas meter is divided into two, which are gas meter chamber 2 and meter inspection chamber 3 respectively. The gas meter chamber 2 is provided with a gas meter 12, and the partition plate 4 is provided with a meter reading window 41. When manual meter inspection is adopted, it is convenient for meter reading personnel to check the gas meter 12 through the meter inspection room 3 and the meter reading window 41. . An electromagnetic lock 5 is also provided in the gas meter box 1, and the electromagnetic lock 5 is fixed on the inner side of the gas meter box 1 and is used to lock the separating partition 4. The electromagnetic lock 5 is electrically connected with the electromagnetic lock un...
Embodiment 3
[0045] On the basis of embodiment one or embodiment two,
[0046] This collector comprises single-chip microcomputer and TC35i module, and this single-chip microcomputer selects At89C51 single-chip microcomputer for use, and this At89C51 single-chip microcomputer is connected with gas meter 12 through RS485 serial communication interface, 485 bus line, and this At89C51 single-chip microcomputer is electrically connected with TC35i module by MAX232A conversion level, and TC35i module is connected with TC35i module The GSM communication module is electrically connected.
[0047] As a preference, the collector can also be provided with an LCD data display module and an EEPROM module, such as SMS control center number, gas meter 12 address information and other system data can be stored in the EEPROM module to play the role of power-down protection.
