Description
Technical Field
The utility model relates to a technical field of electron trade auxiliary device especially relates to a firmware upgrading interface.
Background
It is well known that firmware upgrades are unavoidable for electronic devices. In order to facilitate firmware upgrading, a firmware upgrading interface is often externally arranged outside the device, and currently, common firmware upgrading interfaces include RS232, RS485, USB and network ports, but hardware circuits of the interfaces are relatively complex, the occupied area of a circuit board is large, and the cost is high.
In addition, the traditional firmware upgrading method is local wired upgrading, and if the field environment of the equipment is severe or the local upgrading cost is too high, wireless upgrading of the firmware is a good solution.
SUMMERY OF THE UTILITY MODEL
In order to solve the technical problem, the utility model provides a firmware upgrading interface can realize electronic equipment's nothing and dismantle firmware upgrading, improves and uses the convenience.
The utility model discloses a firmware upgrading interface, including SWD firmware upgrading interface, ZIGBEE wireless module and MCU treater, the SWD firmware upgrading interface is drawn forth from the MCU treater, ZIGBEE wireless module passes through the serial ports and is connected with the MCU treater.
Compared with the prior art, the beneficial effects of the utility model are that: firstly, local online upgrading of firmware is realized through an SWD firmware upgrading interface without disassembling equipment; and secondly, wireless upgrading of the equipment is realized through a ZIGBEE wireless module.
Drawings
Fig. 1 is a schematic structural diagram of the present invention;
FIG. 2 is a ZIGBEE interface connection schematic;
in the drawings, the reference numbers: 1. an SWD firmware upgrade interface; 2. a ZIGBEE wireless module; 3. an MCU processor.
Detailed Description
The following detailed description of the embodiments of the present invention is provided with reference to the accompanying drawings and examples. The following examples are intended to illustrate the invention, but are not intended to limit the scope of the invention.
As shown in fig. 1 to 2, the firmware upgrade interface of the present invention includes an SWD firmware upgrade interface 1, a ZIGBEE wireless module 2 and an MCU processor 3, wherein the SWD firmware upgrade interface 1 is led out from the MCU processor 3, and the ZIGBEE wireless module 2 is connected to the MCU processor 3 through a serial port; the SWD firmware upgrade interface 1 is developed by ARM company, and aims to reduce the number of pins used by a debugging download interface, and the SWD firmware upgrade interface 1 uses two signal lines: the bidirectional data line SWDIO and the clock signal SWDCK used for the data line adopt the novel SWD firmware upgrade interface 1, one reason is that the SWD firmware upgrade interface 1 has simple circuit, two pins are directly led out from the MCU processor 3, and a power supply and a ground can be used, compared with other interfaces, the circuit board layout space is saved, and the cost is also saved, the other important reason is that the SWD firmware upgrade interface 1 supports online debugging, the ZIGBEE wireless module 2 is a local area network communication device, and the ZIGBEE network is mainly characterized by low power consumption, low cost, low speed, a large number of nodes, multiple network topologies, low complexity, rapidness, reliability and safety, and is mainly suitable for the fields of automatic control and remote control, various devices can be embedded, ZIGBEE is a cheap and low-power-consumption short-distance wireless networking communication technology, and the China school enterprise alliance of the Internet of things considers that: ZIGBEE is as a short distance wireless communication technique, because its network can be convenient provide wireless data transmission function for the user, consequently has very strong applicability in the thing networking field, the utility model discloses a wireless transmission device adopts ZIGBEE wireless module 2 to realize, ZIGBEE wireless module 2 links to each other with MCU treater 3 through the serial ports, transmits the upgrading package that will receive for MCU treater 3 to realize the wireless upgrading of equipment, consequently according to above-mentioned content, equipment passes through external SWD firmware upgrading interface 1 and built-in ZIGBEE wireless module 2, can conveniently realize the firmware upgrading of equipment.
The utility model discloses a firmware upgrading interface, above-mentioned all power consumption modules and be the common electrical part in market with electrical apparatus, only need when buying back the use to connect according to the mutual electricity of the instruction manual of buying back together and can use, and control module is its common from taking the module, so all no longer describe here.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be regarded as the protection scope of the present invention.
