A communication link is constructed between the image forming device and the consumable chip by adopting a mode of combining a short-distance wireless communication network with physical signal contact, so that the problem of contact between the image forming device and the chip is solved.
Since the control board of the consumable chip itself has no power source, it is necessary to draw a power cord from the image forming apparatus body to supply power or to supply power using a battery. Because of the close range wireless communication technology adopted by the communication between the image forming device and the consumable chip, in order to prevent the image forming device from erroneously detecting the non-local consumable chip, the address of the image forming device needs to be mutually negotiated between the image forming device and the consumable chip.
As shown in fig. 3, the communication method includes:
s101: based on the connection of the connection terminal of the consumable chip side and the connection pin of the image forming device side, the consumable chip receives preset address information sent by the image forming device.

S104: based on the multicast information, the image forming device judges whether the communication address information accords with the expectation, and if so, wireless communication connection is established with the consumable chip based on the communication address information.
In S101, the connection between the connection terminal on the consumable chip side and the connection pin on the image forming apparatus side is wired, and the connection modes are four, as shown in fig. 4 to 7, wherein the wireless communication module uses a bluetooth/zigbee module and a chip control unit as a chip MCU for illustration, and specifically includes:
as shown in fig. 4, the first image forming apparatus and the consumable chip adopt a three-wire connection method.
The Bluetooth/Zigbee module of the image forming device and a chip MCU (Microcontroller Unit, micro control unit) of the consumable chip are connected in a three-wire mode.
The connection terminal of the consumable chip side may include a VCC terminal for receiving power supplied from the image forming apparatus when the consumable is mounted to the image forming apparatus, a GND terminal, and a communication terminal (IO port terminal); the GND terminal is for connecting with a GND pin on the image forming apparatus side when the consumable part is mounted on the image forming apparatus so as to be grounded; the communication terminal is used for being connected with a communication pin at the side of the image forming device when the consumable is installed on the image forming device, so that communication between the image forming device and the consumable chip is realized, and communication address information of a wireless communication module inside the chip MCU can be transmitted to the consumable chip in a single bus protocol mode before the image forming device communicates with the chip MCU.
As shown in fig. 5, the bluetooth/Zigbee module of the second consumable chip self-powered image forming apparatus and the MCU chip of the consumable chip adopt a line connection mode.
The battery is arranged on the substrate of the consumable chip and is used for providing power for the chip MCU of the consumable chip, and the consumable chip side can be only provided with a communication terminal and is used for being connected with a communication pin on the image forming device side when the consumable is installed on the image forming device, so that communication between the consumable chip and the image forming device is realized.
When the consumable is mounted on the image forming apparatus, the consumable chip is directly connected with the housing of the image forming apparatus, thereby realizing the grounding of the consumable chip.
As shown in fig. 6, the third image forming apparatus and the consumable chip are connected by two wires.
The consumable chip side is provided with a VCC terminal and a communication terminal, wherein the VCC terminal is used for receiving power supplied by the image forming device when the consumable is installed on the image forming device; the communication terminal is used for being connected with a communication pin on the side of the image forming device when the consumable part is installed on the image forming device, so that communication between the image forming device and the consumable part chip is realized.
When the consumable is mounted on the image forming apparatus, the consumable chip is directly connected with the housing of the image forming apparatus, thereby realizing the grounding of the consumable chip.
As shown in fig. 7, the fourth image forming apparatus is connected to the consumable chip by two wires, and the power supply of the consumable chip is stolen from the communication wire between the image forming apparatus and the consumable chip.
The consumable chip side is provided with a communication terminal and a GND terminal and a power supply circuit, wherein the power supply circuit comprises a diode and a capacitor and is used for acquiring stable direct-current voltage from the image forming device side when the consumable chip is mounted on the image forming device, so that power supply is provided for the consumable chip. The GND terminal is for connecting with a GND pin on the image forming apparatus side when the consumable part is mounted on the image forming apparatus so as to be grounded; the communication terminal is used for being connected with a communication pin on the side of the image forming device when the consumable is installed on the image forming device, so that communication between the image forming device and the consumable chip is realized; wherein the power supply circuit is specifically configured to extract electric power from an electric signal received from a communication terminal on the consumable chip side when the consumable is mounted on the image forming apparatus, thereby supplying power to the consumable chip.
This approach requires that the amount of continuous low level transmission between the bluetooth/Zigbee module of the image forming apparatus and the chip MCU of the consumable chip cannot exceed a certain limit, and that the time to maintain the high level is greater than a certain limit for a certain time, and the specific time requirement is determined by the capacitance on the control board of the chip MCU and the operating voltage range of the chip MCU.
Optionally, before performing S102, the following steps may be performed:
and generating preset address information based on the preset random number according to a preset rule.
Specifically, the image forming apparatus generates a preset random number of 1 byte, and then processes the preset random number according to a preset rule to generate preset address information of 4 bytes in length.
