Embodiment 1

[0017] Such as figure 1 As shown, the telemetry terminal system using GPS satellites includes a collection terminal and at least one telemetry terminal. The telemetry terminal is wirelessly connected to the collection terminal through GPS satellites. The telemetry terminal includes a CPU core unit and a GPRS wireless data transmission unit A and the collection control unit, the collection control unit and the GPRS wireless data transmission unit A are all connected to the CPU core unit, the collection control unit is externally connected with sensors, and the collection master station includes the GPRS wireless data transmission unit B and the central processing unit. In the present invention, the telemetry terminal is used to control the work of each sensor at the outer end. The sensor includes a rain gauge, a water level gauge, a displacement meter, a flow meter, etc., and the acquisition control unit includes a digital switch, an analog switch, a pulse switch, etc. , the se...

Embodiment 2

[0020] Such as figure 2 , the structure of this embodiment is basically the same as that of Embodiment 1, the difference is that the telemetry terminal also includes an anti-sabotage unit, the anti-sabotage unit includes an infrared sensor and an alarm, and the control terminal of the alarm is connected to the CPU On the core unit, the output end of the infrared sensor is connected to the CPU core unit. When the infrared sensor senses that an animal is approaching, it sends a signal to the CPU core unit, and the CPU core unit controls the siren to send out an alarm, mainly to scare off animals such as mice. , when the staff needs to check the telemetry terminal, they can first control to turn off the infrared sensor.

Embodiment 3

[0022] Such as image 3 , the structure of this embodiment is basically the same as that of Embodiment 2, the difference is that the telemetry terminal also includes a memory, which is connected to the CPU core unit, and the memory is used to store the data of the telemetry machine test, so that the total station can call its measurement at any time at any time data.

[0023] [Example 3]

[0024] Such as Figure 4 , the structure of this embodiment is basically the same as that of Embodiment 3, the difference is that the telemetry terminal also includes a status indication unit, the status indication unit is connected to the CPU core unit, the status indication unit includes an LED light, and the status indication unit of the present invention The indicator unit includes three LED lights, which are red, yellow and green. The red light represents the power indicator, the green light represents the communication indicator, and the yellow light represents the data transmission ...

Abstract

The invention discloses a telemetry terminal system adopting a GPS satellite. The telemetry terminal system adopting the GPS satellite comprises a collection master station and at least one telemetry terminal, the telemetry terminal system is connected to the collection master station through the GPS satellite, the telemetry terminal comprises a CPU core unit, a GPRS wireless data transmission unit A and a collection controlling unit, the collection controlling unit and the GPRS wireless data transmission unit A are both connected to the CPU core unit, a sensor is externally connected with the collection controlling unit, and the collection master station comprises a GPRS wireless data transmission unit B and a central processor. The telemetry terminal system adopting the GPRS satellite has the advantages that the GPS satellite is adopted to be used as a relay to carry out data transmission, data transmission distance is prolonged, the number of collection master stations is reduced, and a large amount of manpower and material resources are saved.

Description

technical field [0001] The invention relates to the field of wireless monitoring, in particular to a remote measurement terminal system using GPS satellites. Background technique [0002] Telemetry monitoring is used in many ways, especially in hydrology. The hydrological department needs to conduct real-time monitoring of hydrological parameters such as rivers, lakes, reservoirs, channels and groundwater. The monitoring content includes: water level, flow, flow velocity, rainfall (snow), evaporation, sediment, ice, moisture, water quality, etc., so The system uses wireless communication to transmit monitoring data in real time, which makes the work efficiency of the hydrological department very high. However, the existing telemetry terminals placed in the field use wireless antennas for data transmission. The transmission distance of wireless antennas is too short. When performing telemetry at a location, it is necessary to set up a convergence terminal nearby to receive d...
