(1) read real-time pressure, temperature data from data capsule,

(2) setting data box mode of operation

(3) setting data box frequency acquisition.

The processor read functions key value of telepilot, and to judge be to read real-time pressure, temperature data, or setting data box mode of operation, or setting data box frequency acquisition, send order according to the key value judged result to data capsule, and receive the data that data capsule sends, to read real-time pressure, temperature value or data capsule running status numerical value.The result can show on LCD display after these data process processor computings.

The upper computer analyzing software of host computer sends the reading of data order for the field data box by radio receiving transmitting module, the pending data box is accepted field data box data after responding, and do computing, handle and can analyze preventer serviceable life and safety case by predetermined requirement.

Advantage of the present invention is:

1. on-the-spot embedded data capsule has adopted Low-power Technology, has realized that whole system is battery-powered, has solved preventer and has used the inconvenient and explosion-proof problem of on-the-spot power supply.

2. the field data box is embedded in the blowout prevention body, has overcome on-the-spot inconvenience of installing.Very strong antijamming capability is arranged, can long-term continuous working under abominable field condition.

3. on-the-spot embedded data capsule uses jumbo nonvolatile memory, has realized preserving the long-time running data, provides the foundation of science serviceable life for judging preventer.Even the field data box damages in the use, just can the playback record data come as long as storer is harmless, played the effect of " black box ".

4. remote controller displays field data box running status and real-time pressure, temperature data, the handled easily personnel grasp the data capsule working condition at any time.

5. host computer is done computing to historical data, handles and can analyze preventer serviceable life and safety case by predetermined requirement.

6. radio communication between field data box and telepilot and the host computer has overcome the difficulty of field wiring inconvenience.
