Embodiment 1

[0058] In order to solve the above-mentioned technical problems existing in the prior art, an embodiment of the present invention provides a half-duplex communication circuit.

[0059] figure 1 It is a topological diagram of an embodiment of the half-duplex communication circuit of the present invention, such as figure 1 As shown, the half-duplex communication circuit of this embodiment may include a first transceiver module 10 and a second transceiver module 11; the first transceiver module 10 includes a first transmitting port TX_A, a first transmitting unit U1, a first receiving port RX_A and The first receiving unit U2; the second transceiver module 11 includes a second sending port TX, a second sending unit U3, a second receiving port RX and a second receiving unit U4. Wherein, the first transmitting port TX_A, the first transmitting unit U1, the second receiving unit U4 and the second receiving port RX are sequentially connected, the first transmitting port TX_A is used...

Embodiment 2

[0064] figure 2 It is a topological diagram of another embodiment of the half-duplex communication circuit of the present invention, such as figure 2 As shown, the half-duplex communication circuit of this embodiment is based on the above embodiments, and the first receiving unit U2 is also connected to the first sending unit U1; the second receiving unit U4 is also connected to the second sending unit U3.

[0065] In a specific implementation process, the first sending unit U1 outputs the first conversion signal to the first receiving unit U2, so that the first receiving unit U2 and the second receiving unit U4 output the input signal of the second control chip synchronously; thus, the first receiving unit U2 A receiving unit U2 can feed back the input signal of the second control chip to the first control chip, so that when the first control chip detects that the level of the input signal of the second control chip is inconsistent with the level of the output signal of the...

Embodiment 3

[0076] image 3 It is a schematic structural diagram of an embodiment of a half-duplex communication device of the present invention, such as image 3 As shown, the half-duplex communication device of this embodiment includes a first control chip 30, a second control chip 31, and the half-duplex communication circuit 32 of the above-mentioned embodiment; wherein, the first control chip 30 and the second control chip 31 Communication is carried out through the half-duplex communication circuit 32, and the first control chip 30 can communicate with the first transceiver module 10 in the half-duplex communication circuit 32, and the second control chip 31 can communicate with the first transceiver module 10 in the half-duplex communication circuit 32. Two transceiver modules 11 are communicatively connected; certainly, the first control chip 30 can be communicatively connected with the second transceiver module 11 in the half-duplex communication circuit 32, and the second contro...

Abstract

The invention discloses a half-duplex communication circuit and device and electrical equipment. The half-duplex communication circuit comprises two transceiving modules, each transceiver module comprises a sending port, a sending unit, a signal output serial port of a receiving end and a receiving unit. In the communication process of the two communication objects, only after the sending port inone receiving and sending module receives the communication signal of one communication object, the communication signal is sent to the receiving and sending module; the received communication signalis sent to a receiving port in the other transceiving module through the sending unit in the transceiving module and the receiving unit in the other transceiving module; then the signals are sent to the other communication object through the receiving port in the other receiving and sending module; thus, on the premise that a communication module is not arranged, communication of the two communication objects is achieved, the use of electrical apparatus elements is reduced, the production cost of the product is reduced, meanwhile, due to the adoption of the half-duplex communication technology, only one communication line is needed between the two communication objects for communication, wiring in the product is simple, and the design difficulty of the product is reduced.

Description

technical field [0001] The invention belongs to the technical field of electronic circuits, and in particular relates to a half-duplex communication circuit, device and electrical equipment. Background technique [0002] Nowadays, there are more and more functions of various electrical equipment on the market, and it is often necessary to install multiple control chips in the electrical equipment, and realize various functions by using the communication between the control chips. [0003] Usually, the communication between the control chips in the electrical equipment often needs to set up a special communication module such as R485 to realize it. However, for electrical equipment such as vacuum cleaners and sweeping robots, due to the small internal space and additional communication modules, the number of communication lines used is large, making product design more difficult. Contents of the invention [0004] The main purpose of the present invention is to provide a h...
