一种400kHz与800MHz混合通信装置
摘要：
本实用新型提供了一种400kHz与800MHz混合通信装置，所述装置包括：第一发射接收机(100)和第二发射接收机(200)，分别以400kHz和第800MHz发送和接收无线数据和特征信息，且该两种发射接收机同时工作；以及控制器(300)，与所述第一发射接收机(100)和第二发射接收机(200)电连接，用于根据所述第一发射接收机(100)和第二发射接收机(200)所接收的特征信息的有效性，从所述第一发射接收机100和第二发射接收机200所接收的无线数据中选择有效的无线数据。本实用新型采用两个不同频率的发射接收机进行数据通信，可在无需铁路沿线加设通信补强设备的情况下，保证无线数据的通信可靠，省去了加设通信补强设备的成本。
摘要（英）：

The utility model provides a 400kHz-800mHz hybrid communication device comprising a first transmitter-receiver (100) and a second transmitter-receiver (200) that transmit and receive wireless data and feature information by 400kHz and 800mHz, as well as a controller (300), wherein the two transmitters-receivers simultaneously work; and the controller (300) is electrically connected with the first transmitter-receiver (100) and the second transmitter-receiver (200) and used for selecting effective wireless data from the wireless data received by the first transmitter-receiver (100) and the second transmitter-receiver (200) according to the effectiveness of the feature information received by the first transmitter-receiver (100) and the second transmitter-receiver (200). In the utility model, as the two transmitters-receivers with different frequencies are adopted for data communication, communication of wireless data can be ensured to be reliable under the condition that communication reinforcing equipment is not additionally arranged along a railway, therefore, the cost of additionally arranging the communication reinforcing equipment can be saved.
