Problems solved by technology

[0003] Although my country's coalbed methane resources are very rich, the mining process is difficult, and it is usually necessary to measure various data, and the measurement environment is harsh. In the deep underground, the temperature difference is large, and it is prone to danger. Various data sensors are used for data analysis. Acquisition can solve this problem, but because the sensor goes deep into the coalbed methane well, it is very difficult to transmit data, control, and perform alarm processing, etc. There is a lack of a device that can control the sensor in real time and is easy to operate

Embodiment 1

[0052] Such as figure 1 As shown, the remote intelligent measurement and control system for coalbed methane wells described in Embodiment 1 of the present invention includes: data acquisition module 1, signal output module 2, data storage module 3, data processing module 4, configuration file setting module 5, historical data Supplement module 6, display module 7.

[0053]The data collection module 1 is used to collect the data obtained by monitoring, and read the configuration parameters preset in the configuration file setting module 5 during data collection, and when the collected data is abnormal, record the abnormal data to the data storage module 3 middle;

[0054] Further, the data acquisition module 1 can also be used to read the acquisition cycle frequency set in the configuration file setting module 5 when performing data acquisition initialization, and perform data acquisition automatically or manually;

[0055] The signal output module 2 is used to receive the co...

Embodiment 2

[0067] Embodiment 2 provides a remote intelligent measurement and control method for coalbed methane wells.

[0068] In this embodiment, the production monitoring of the pumping unit in a coalbed methane well is taken as an example to illustrate, as figure 2 Shown:

[0069] The well site has two production wells, using a pumping unit as the main drainage equipment and a gas generator as the power source. The monitoring equipment is placed in the monitoring box, and the on-site instruments are connected by cable.

[0070] Among them, the monitoring box includes a coalbed methane well remote intelligent measurement and control terminal (hereinafter referred to as the terminal), a 24V DC power supply, a DTU (Data transmission Unit, data transmission unit), several terminal blocks, and a surge protector. The 24V power supply is used as the power supply for the main equipment, mainly providing power sources for the measurement and control terminals, DTU and field sensors. The si...

Embodiment 3

[0092] Embodiment 3 provides a remote intelligent measurement and control terminal for coalbed methane wells, such as Figure 5 As shown, the terminal includes: a main processor, a first memory, a second memory, a first converter, a second converter, and a network access device;

[0093] Wherein, the main processor is connected with the first memory, the second memory, the first converter, the second converter, and the network access device, and the main processor reads the remote intelligent measurement and control program stored in the second memory into the first The remote intelligent measurement and control program is run in a memory, the main processor receives the data sent by the sensor through the first converter and analyzes and processes it, and returns the processing result to the sensor through the second converter, and the main processor receives the external data through the network access device. Send the control command and return the receipt message;

Abstract

The invention discloses a remote intelligent measurement and control system, method and terminal for coal-bed methane wells. The remote intelligent measurement and control terminal for coal-bed methane wells can be connected with a sensor commonly used in a coal-bed methane well site so as to carry out data acquisition under harsh field conditions and control remote sensors; field equipment and instrument are intensively displayed in a dial-less manner; and the effects of remote data alarm, historical data storage, and the like can be achieved.

Description

technical field [0001] The invention relates to the field of automatic control of coalbed methane development, in particular to a remote intelligent measurement and control system, method and terminal for coalbed methane wells. Background technique [0002] Coalbed methane is a high-quality and clean energy source, which mainly exists in the coal seam in an adsorbed state, and a small amount exists in pores and cracks in a free state. From the perspective of national economic development, due to the development and utilization of coalbed methane, a large amount of high-quality clean energy that is likely to be wasted has been recovered, which has played a positive role in alleviating energy shortages and promoting national economic development. [0003] Although my country's coalbed methane resources are very rich, the mining process is difficult, and it is usually necessary to measure various data, and the measurement environment is harsh. In the deep underground, the tempe...
