Description

The present invention monitors the rapid changes in the gas usage and external environment in the gas meter body, takes immediate measures, and uses Zigbee short-range wireless communication technology to provide emergency status information to GSM modules, telephone line modules, and wireless Communication to the broadband network, etc., or re-transmission from the broadband network to the network administrator so that the administrator (natural gas company or gas supplier) can immediately know the safety status of each gas meter and take the necessary countermeasures. The present invention relates to a detection transmission system in the control of gas.

  In ordinary households, the use of gas for cooking food is quite prevalent, and in response to customer convenience needs, many gas companies lay pipelines widely and require gas The amount of gas used is calculated using a gas meter connected to each household and equipped with a measuring unit inside. Currently used gas meters have been in use for many years, but their function is limited to calculating the amount of gas used, and it is not possible to judge whether the gas pipeline is leaking or the intensity of the earthquake. I can't respond immediately. However, leaks of pipelines or pipeline breaks due to earthquakes often occur instantaneously and without notice, and therefore the use of conventional gas meters poses a risk of gas leaks.

  Also, in the market, some sensor parts are installed in the gas meter to detect information such as gas leaks in the gas pipeline and earthquake intensity, and this information is managed by broadband network or existing telephone line A new gas meter has appeared that is transmitted to the user and allows the administrator to grasp the correlation information of the gas meter.

However, the structure of the conventional product described above still has the following disadvantages in manufacturing and use.
1. In the conventional structure, the transmission of data must be transmitted to the administrator side via a broadband network or an existing telephone line, and while the transmission is fast, the cost of the broadband network or the existing telephone line and the cost of the communication equipment are increased. High, incurs administrative costs and user costs.
2. In the conventional structure, if the user is behind with telephone charges or network charges, the administrator cannot monitor and take emergency measures in real time when an emergency such as a major earthquake occurs.
3. Since each gas meter communicates with the manager alone, not only is the pipeline installation cost enormous, but also exchanges information between neighboring gas meters (for example, gas meters between the upper and lower floors of the apartment complex). It can't be done and is costly.
Currently, there are some in the market that transmit the data of the gas meter to the administrator side by wireless method such as CDMA / GSM or Bluetooth.
However, with the above-mentioned structure, regardless of CDMA / GSM or Bluetooth, the consumption of electricity is large. The life of traditional rechargeable batteries does not exceed an average of 7 days, while the safety of gas meters is year to year. It must be monitored and reliable and stable transmission must be ensured. A CDMA / GSM or Bluetooth communication system has a huge power consumption and high battery renewal rate, and the cost is relatively high; and the amount of information in the gas meter is very small, and a large amount of data transmission like CDMA / GSM Broadband space that is not needed and not used is a waste of network resources.

      The inventor of this proposal, in light of the shortcomings associated with the implementation of the conventional gas meter and data transmission system described above, and based on the accumulated experience in the development of personal related industries over the years, finally, after the earnest study, We have succeeded in developing a detection transmission system for gas meter monitoring using distance wireless communication technology.

Incidentally, Zigbee is a short-range wireless network technology characterized by very little power consumption, and has advantages such as low cost, low power consumption, two-way transmission, induction network function, and transmission range is 100 Beyond the meter, the transmission rate reaches 250Kbps, the number of nodes that can support star-shaped, crowded or net-like arrangement reaches 65000, low power consumption and low cost with Zigbee products can be used for months to years even with ordinary battery power Therefore, Zigbee has a wide range of applications and is mainly used for low transmission rate and low power applications and environmental data collection.

The main purpose of the present invention is to use the two-way transmission Zigbee short-range wireless communication technology to transmit emergency information to the manager, who knows the safety status of each gas meter in real time and is necessary It is an object of the present invention to provide a detection transmission system in gas control capable of taking appropriate first-aid measures and maintaining long-term wireless use stability and saving installation costs and power consumption.

  The present invention includes a number of gas meter bodies and a central control module, wherein the gas meter body includes at least a sensor module, a control unit, and a gas cutout valve; The control unit receives the detection information of the sensor module and performs related processing and feedback; the gas cutout valve controls the control unit of the control unit. In response to the activation, the gas flow is interrupted; a plurality of short-distance transmission units are connected to the respective gas meter bodies, thereby transmitting detection information fed back by the control unit in each gas meter body, and The distance transmission unit adopts Zigbee short-range wireless communication standard, Any two short-range transmission units can exchange information with each other at a distance not exceeding 100 meters; the central control module collects information transmitted by each short-range transmission unit in the area, and Confirm that the information detected in the gas meter body has been smoothly transmitted to the central control module by each short-distance transmission unit, and feed back to the target gas meter body that has not yet transmitted information in the area. Requesting and transmitting the request to the control unit of the target gas meter body by each short-distance transmission unit.

Due to the above structure, in use, the control unit in each gas meter main body performs emergency command treatment for abnormal usage conditions, and immediately sends relevant information to each other through each short-distance transmission unit. It is transmitted to modules, wireless broadband networks, etc., or compiled and organized on the broadband network, and then retransmitted to the central control module so that the administrator can organize and organize the information and perform the necessary first aid measures. I can do it.

From the above embodiment, it can be seen that the present invention has the following advantages.
(1) The present invention uses Zigbee short-range communication technology, does not go through existing broadband networks or telephone lines, and Zigbee has low cost and power compared to wireless systems such as CDMA / GSM or Bluetooth technology. It has advantages such as low consumption, two-way transmission, and de-used network function, thus saving system cost and power resources.
(2) The present invention adopts wireless communication and Zigbee's low power consumption features make it possible to use existing telephone lines or broadband network circuits in the event of an emergency such as a major earthquake. Administrators can still seize and monitor and respond to information in real time.
(3) The Zigbee short-range communication technology adopted by the present invention uses the short-range transmission unit 2 between nearby gas meters (for example, the gas meter between the upper and lower floors of the apartment complex) as a stepping stone until it reaches the central control module 4 side alternately. By transmitting information and making full use of the large information network in the nearby short distance transmission unit 2 in the gas meter, interactive mutual transmission of data can be achieved, saving the cost of system construction and achieving an efficient transmission strategy.
(4) The present invention can efficiently transmit gas-related information and reduce the cost of the gas meter / gas meter communication facility and the gas meter communication cost.
(5) The present invention solves the trouble of copying the meter frequency by the traditional manpower, and transmits the gas meter frequency of each user to a natural gas company or a gas company by using the short distance transmission unit 2 as a stepping stone, and dispatches people. This saves labor costs by saving the trouble of copying the meter frequency.

First, referring to FIGS. 1 and 2, the present invention comprises a large number of gas meter bodies 1, a plurality of short-distance transmission units 2, and a central control module 4.
The gas meter body 1 includes at least a sensor module 11, a control unit 12, a gas cutout valve 13, and an LED warning lamp 14.

  The sensor module 11 can read related basic data of the gas meter main body (for example, gas meter frequency, gas meter name, gas meter status), etc., as well as a pressure sensor unit 111, a flow sensor unit 112, and an earthquake sensor, respectively. A unit 113 is provided.

The pressure sensor unit 111 detects gas pressure, and immediately transmits information to the control unit 12 when a gas pressure abnormality is detected.
The flow sensor unit 112 is for detecting the gas flow rate, and immediately transmits information to the control unit 12 when an abnormal gas flow rate is detected.

The earthquake sensor unit 113 is for detecting whether there is an earthquake, and immediately transmits information to the control unit 12 when an earthquake occurrence is detected.
The control unit 12 is for receiving information such as pressure / flow rate / earthquake and gas meter basic related data detected by the sensor module 11 and further performs related processing and feedback.

  The gas cutout valve 13 is activated under the control of the control unit 12 and immediately shuts off the gas flow when pressure generation, flow rate abnormality, or a serious earthquake occurs.

  The LED warning lamp 14 is connected to the control unit 12, and when abnormality information occurs, the LED warning lamp 14 receives a control of the control unit 12 and outputs a warning lamp signal.

  A plurality of short-distance transmission units 2 are connected to each gas meter main body 1 and transmit information such as detected pressure, flow rate, and earthquake fed back from the control unit 12 in each gas meter main body 1. The unit 2 adopts the Zigbee short-range wireless communication standard, and allows any two short-range transmission units 2 to exchange information with each other within a distance not exceeding 100 meters.

  The central control module 4 summarizes and organizes information transmitted from each short-distance transmission unit 2 in the area, and information such as pressure, flow rate, and earthquake detected in each gas meter main body 1 is steadily displayed. In addition to ensuring that the distance transmission unit 2 transmits to the central control module 4, it requests the target gas meter body 1 that has not yet transmitted information within the area to provide feedback, and transmits this request to each short distance transmission. The data is transmitted between the units 2 to the control unit 12 of the target gas meter main body 1.

  The above-described system configuration can be applied to an urban complex as shown in FIGS. 1 and 2, and the gas meter of each resident in the upper and lower floors and the left and right sides is controlled by the control unit 12 in the gas meter main body 1 of each household. An emergency command is taken for abnormal use conditions, and the relevant information is immediately transmitted to the central control module 4 of the area by each short-distance transmission unit 2 in the gas meter main body 1 arranged in each household, and the administrator summarizes it. -For control, the central control module 4 can easily confirm the position based on the information number sent from the target gas meter main body 1 and can take necessary emergency measures, for example, dispatching personnel urgently Completely repair and inspect, or shut off the gas when the gas is tightened, and control units in multiple sets of gas meter body 1 By crossing control information transmitted from the 2, understand events such as earthquakes, flow rate abnormality-pressure abnormality of a large range, assist in the development of subsequent action.

  Furthermore, it is used to transmit the gas meter frequency record in the gas meter main body 1 of each user, and the natural gas company or gas supplier can acquire the gas meter frequency in real time without sending a person and copying the meter frequency. Can solve the inconvenience of copying the meter frequency manually.

As shown in FIGS. 1, 2, and 3, when another earthquake sensor unit 113 in the gas meter main body 1 at a certain location detects an earthquake occurrence a, the control unit 12 immediately uses the gas b at that time. Determine if it was in the middle.
If it is not in use, it is set as unprocessed c. If it is in use, it immediately sends a signal to the gas cut-out valve to shut off the gas, and also outputs a warning lamp signal e from the LED warning lamp to inform the user. In addition, the information is transmitted to the central control module f through the short-distance transmission unit, and the observer grasps the earthquake information at the initial stage of the incident and ensures that the information is received and the necessary treatment is performed using the central control module. .

  If the information is leaked or delayed in the middle, a message requesting feedback is transmitted to the control unit 12 of the target gas meter body 1 between each short-distance transmission unit 2 and sent to the control unit 12. It is possible to instruct to feed back earthquake information through the short distance transmission hot water knit 2 again.

When the flow rate sensor unit 112 in the gas meter main body 1 detects the gas flow rate abnormality g, the control unit 12 immediately determines whether or not the set value i has been exceeded. If so, a signal is immediately sent to the gas cutout valve to shut off the gas and the LED warning lamp emits a warning lamp signal e to warn the user.
At the same time, the information is sent to the central control module f through the short-distance transmission unit so that the monitor can grasp the gas flow rate information at the first time.

When the pressure sensor unit 111 in the gas meter body 1 detects a pressure abnormality h in the gas meter, the control unit 12 immediately determines whether the set value i has been exceeded at that time.
If it does not exceed, set to unprocessed c, and if it exceeds the set value, immediately send a signal to the gas cutout valve to shut off the gas d, and the LED warning lamp emits warning lamp signal e to the user Warning.
At the same time, information is sent to the central control module f of the area through the short-distance transmission unit so that the observer can grasp the gas pressure information at the initial stage of the incident occurrence.

  In the second embodiment of the present invention, as shown in FIG. 4, in the above-described system, in the transmission process of the short distance transmission unit 2, the distance exceeds the effective transmission range between any two short distance transmission units 2. In this case, at least one repeater 4 may be provided between the two short distance transmission units 2 and the feedback information may be transferred through the repeater 4.

  As shown in FIG. 5, in the third embodiment of the present invention, in the above system, the short distance transmission unit 2 is not directly installed in the gas meter main body 1 but is separately connected to the control unit 12 in the gas meter main body. An RS232 transmitter 15 is provided, connected to the short-distance transmission unit 2 installed outside through the RS232 transmitter 15, and detection information to be fed back by the control unit 12 to the short-distance transmission unit 2 via the RS232 transmitter 15. Just communicate.

  General old type gas meter does not support Zigbee short-range wireless communication technology, so it will be expensive to replace it completely, so RS232 transmitter 15 is adopted first to send data to external short-range transmission unit Then, information such as pressure, flow rate, and earthquake detected in the gas meter main body 1 may be smoothly transmitted to the central control module 4 through the alternate transmission of the short distance transmission units 2.
