detailed description

Below in conjunction with accompanying drawing and specific embodiment the utility model is further introduced.

Embodiment 1: as shown in Figure 1, a kind of automatic meter reading system based on ZigBee comprises collector, ZigBee wireless module, ZigBee coordinator and remote monitoring terminal, and collector is connected to ammeter by RS485, is connected to by ZigBee wireless module ZigBee coordinator, the ZigBee coordinator is connected to the remote monitoring terminal through GPRS wireless module 1, the remote monitoring terminal is also equipped with GPRS wireless module 2, GPRS wireless module 2 is connected to the mobile phone of the householder, the main control chip of the ZigBee wireless module adopts CC2530 chip, ZigBee The main control chip of the coordinator adopts PIC18F4620 chip, the first GPRS wireless module adopts MC35, and the second GPRS wireless module can also be connected to a tablet computer.

The remote monitoring terminal collects the information of the ZigBee coordinator through the channel and sends corresponding instructions. It has strong data processing and storage functions. After receiving the data from the GPRS network, it restores the data through software and analyzes it. Calculation, storage, verification, management, etc., and the analysis results are used as the basis for the selection of remote control strategies to achieve a comprehensive grasp of power consumption and facilitate management.

The FlashROM in the PIC18F4620 chip is used to store application programs and communication protocols; the UART interface is connected to the GPRS wireless communication module; the SPI interface is connected to the ZigBee wireless communication module; the 10bit A/D converter realizes battery voltage detection and analog input; the rest of the general I The /O port realizes various control and transmission functions of the concentrator respectively. The ZigBee coordinator node in the concentrator is connected with the MCU of the concentrator through RS232 serial port communication.

The wireless communication module used in GPRS wireless module one is MC35. MC35 module is mainly composed of RF antenna, internal Flash, SRAM, GSM baseband processor, matching power supply and a 40-pin ZIF socket. The GSM baseband processor is the core component, and its function is equivalent to a protocol processor, which is used to process the AT commands sent by the external system through the serial port. The radio frequency antenna part mainly realizes signal modulation and demodulation, and signal conversion between external radio frequency signal and internal baseband processor.

The main control chip of the radio frequency transceiver module of the ZigBee network is CC2530, which is a 2.4G radio frequency transceiver that TI recently released in line with the IEEE802.15.4 standard. The operating frequency range of this chip is 2400-2483.6MHz, and it supports a data transmission rate up to 250Kbit/s, which can realize multipoint-to-multipoint fast networking.

The collector is also a collection terminal, that is, the data collection node of the meter. The node mainly completes the following functions: responsible for collecting and transmitting the counts of each meter and monitoring the operating status of the meter; sending heartbeat information regularly to determine whether it has lost contact with the network. If not in the network, Reconnect to the network at regular intervals; do corresponding actions according to the instructions sent by the coordinator, and send the received data to the meter through RS485 to collect data instructions and time synchronization instructions.
