Problems solved by technology

[0005] The biggest problem with this system is that it only has the single function of receiving wireless signals and playing them
Especially in the broadcast system terminal system used in emergency evacuation, due to the wide division of system equipment and the large installation range, it is difficult for users to monitor and detect the operation status of terminal equipment in real time. If the terminal equipment cannot operate normally, once If the emergency evacuation notice needs to be broadcast but cannot be played normally, there is an obvious safety hazard

Embodiment 1

[0049] Embodiment 1 Self-inspection type wireless broadcasting terminal system

[0050] The structure of the self-inspection wireless broadcast terminal system is shown in Figure 2. The system includes a wireless base station 1 for receiving and sending instructions, a TETRA digital vehicle-mounted station 2, a power amplifier 3 connected with the TETRA digital vehicle-mounted station 2, a plurality of outdoor horns 4, a microphone 5 located near the outdoor horn 4, and a TETRA digital vehicle-mounted radio. The monitoring processor 6 connected to the platform 2 is equipped with a UPS power supply 7 in the power supply of each device in the system.

[0051] The self-inspection workflow of the system is shown in Figure 3. When the digital vehicle station 2 receives the test command from the base station 1, it first judges the collected UPS self-test results, and directly feeds back the results to the base station 1 if the self-test results are abnormal.

[0052] For the norm...

Embodiment 2

[0057] Embodiment 2 monitoring processor

[0058] The monitoring processor of the present embodiment adopts a common embedded computer design, which includes a shell, a power supply, a main board, a CPU inserted on the main board and a CF card used as storage.

[0059] The motherboard adopts Zhida 3.5' embedded motherboard-SBC-3641, which is equipped with AMDGeode LX800CPU, has 1 SODIMM slot, 4 serial ports (of which COM2 is RS232 / 422 / 485), supports CF card slot, 2 USB2.0 interface, audio receiving port, video receiving port, I / O port, PS / 2, RJ-45, etc.

[0060] As shown in Figure 4, the central processing unit (CPU) and the storage unit 12 adopt a CF memory card, which is integrated with the embedded computer 11 through the CF slot in the embedded computer 11 as a carrier of the system program. The embedded computer 11 transmits the collected data to the CF memory card 12 through its internal collection, control and other systems, and transmits the operation and processing...

Abstract

The invention relates to a radio broadcasting terminal system. The invention provides a self-monitoring type radio broadcasting terminal system, wherein, when sending a test audio, the studio equipment of the system feeds back outdoor audio to the system through an audio collecting device, the system judges the feedback information, thereby the studio equipment is self-monitored partly; when the self-monitoring is started, the system cuts off urban power, which is supplied by the storge battery of the UPS power supply, the self-monitoring of the UPS power supply is started. The self-monitoring type radio broadcasting terminal system of the invention can solve the problems of bad tone quality, easy to be interfered, complex maintenance management, bad interaction performance, unable self-monitoring, improves the performance of the system and reduces hidden danger.

Description

technical field [0001] The invention relates to a wireless broadcasting terminal, in particular to a wireless broadcasting terminal system applying digital trunking technology and having a self-inspection function, a self-inspection method of the system and a dedicated monitoring processor. Background technique [0002] Digital trunking technology has been emerging worldwide since the mid-1990s. It integrates functions such as command and dispatch, telephone, data, short message, multimedia image and overIP. It has been widely used and achieved good social and economic benefits. In our country, with the accelerated pace of social and economic activities, the expansion of scope, and the sharp increase in the amount of information transmission, society as an organic whole needs more coordination and cooperation from all aspects. The increasingly urgent demand provides an economic and market basis for the development of trunking communication systems in my country. In our count...
