Problems solved by technology

The host of this kind of wireless conference system realizes the reception and transmission of the conference unit signal through an external or built-in wireless receiver and transmitter, and only one receiving and transmitting circuit is placed in each unit, so it must face several problems : First, the power of the power supply battery is fixed, and the use time of each charge of the battery is limited. Due to the difference in the frequency and duration of speeches in the venue, some conference units in the venue will quickly run out of power, such as the speaker The power of the guests will be exhausted soon, while other conference units still have a lot of power that is not used; second, the wireless

Example Embodiment

[0025] Example 1:

[0026] Such as figure 1 with figure 2 As shown, this example provides a wireless conference system, including: a host computer 2, a wireless data transceiver 9 and at least two wireless conference units connected to each other; wherein the wireless conference unit includes a battery 3, a main control circuit 1, The low-intensity short-range wireless transceiver circuit 6 and the high-intensity long-range wireless transceiver circuit 7, the battery 3, the low-intensity short-range wireless transceiver circuit 6, and the high-intensity long-range wireless transceiver circuit 7 are respectively connected to the main control circuit 1; The low-intensity short-distance wireless transceiver circuit 6 is used for data transmission before the wireless conference unit; the high-intensity long-distance wireless transceiver circuit 7 is used for the data and data between the host 2 and / or the wireless data transceiver 9 and the wireless conference unit Control signal tr...

Example Embodiment

[0031] Example 2:

[0032] On the basis of embodiment 1, the master unit 5 in this example is used to communicate with the master 2 to transmit audio and control signals; the slave unit 4 turns on the low-intensity short-range wireless transceiver circuit 6 and passes the signal through the low-intensity The short-distance wireless transceiver circuit 6 transmits the data to the main unit 5; the main unit 5 collects data from all the slave units 4 under its coverage, and then communicates the data with the host 2.

[0033] On the basis of setting two transceiver circuits in the wireless conference unit, this example also uses a certain control and selection mechanism, that is, the master-slave selection circuit 8 to select one or several wireless conference units in the entire conference venue as the master unit 5 , Other units serve as auxiliary slave units 4, and the slave unit 4 transmits data to the master unit 5. The master unit 5 then transmits the aggregated data to the mast...

Example Embodiment

[0035] Example 3:

[0036] Such as image 3 As shown, on the basis of Embodiment 1 or Embodiment 2, this example first initializes the wireless conference unit, and then uses the master-slave selection circuit 8 to calculate the number of speeches of each wireless conference unit in a specific time, the speech time and each The identity of the wireless conference unit is used for the initial judgment of the master-slave unit 4, and the primary unit and the primary-selected slave unit of the preliminary judgment are obtained; then the primary unit selected for the initial judgment is compared and analyzed to realize the second judgment. The factors to be judged again include the current power of the primary unit 5, the signal strength received from the host 2 or the host transmitter unit, and the degree of interference with surrounding signals, and then the final master unit 5 and slave unit 4 are selected again, and based on The selected master unit 5 and slave unit 4 configure ...

Abstract

The invention provides a wireless conference system which comprises a host, a wireless data transmitting and receiving device and at least two wireless conference units which are mutually connected. Each wireless conference unit comprises a battery, a main control circuit, a low-strength short-distance wireless transmitting-receiving circuit and a high-strength long-distance wireless transmitting-receiving circuit, wherein the battery, the low-strength short-distance wireless transmitting-receiving circuit and the high-strength long-distance wireless transmitting-receiving circuit are connected with the main control circuit respectively. The low-strength short-distance wireless transmitting-receiving circuits are used for data transmitting among the wireless conference units, and the high-strength long-distance wireless transmitting-receiving circuits are used for transmitting of the data and control signals among the host and/or the wireless data transmitting-receiving device and the wireless conference units. By means of the wireless conference system, electric quantity and transmitted power of every wireless conference unit are utilized reasonably according to actual situations, unnecessary transmitting power consumption is reduced, and the disadvantages of unreasonable role assignments of the wireless conference units and mismatching of the electric quantity, signal strength with actual requirements and the like are avoided.

Description

technical field [0001] The invention relates to a conference system, in particular to a wireless conference system. Background technique [0002] The current wireless conference system communicates with the conference units through a wireless transmitter receiver arranged in the venue, and the size of the venue (the number of conference units) is limited by the communication distance between the wireless transmitter receiver and the unit. The host of this kind of wireless conference system realizes the reception and transmission of the conference unit signal through an external or built-in wireless receiver and transmitter, and only one receiving and transmitting circuit is placed in each unit, so it must face several problems : First, the power of the power supply battery is fixed, and the use time of each charge of the battery is limited. Due to the difference in the frequency and duration of speeches in the venue, some conference units in the venue will quickly run out of...
