Cross preset value, then the pressure information is transmitted in pressure-detecting device in the component of size for judging hydraulic pressure force value again,
To detect the occurrence of the pressure information；If the second judgment component judges that the pressure information beyond preset value, leads to
It crosses the second control element control data transmission device being attached thereto and transmits the first warning message, and then staff is made to understand this
The hydraulic pressure force value of the spray end of pressure monitoring devices position is excessive, and takes corresponding solution in time, this can
To prevent pressure-detecting device impaired, the incidence of safety accident can also be reduced.Specifically, range can be used greater than pressure
Second judgment component of detection device, and in order to save cost, the second judgment component that precision is relatively low can be selected, it is above-mentioned
Preset value can be equal to the value of the maximum range of pressure-detecting device or slightly smaller than pressure inspection also can be set into the preset value
Survey the numerical value of device maximum range.
The hydraulic pressure force value that fire_fighting pipe network can bear is generally in certain section, thus for pipe under test,
It there will necessarily be the limiting value of pressure bearing, hydraulic pressure force value causes pipeline quick-fried beyond the pressure bearing limiting value of pipeline in order to prevent
It splits；Meanwhile manifold pressure is inadequate or anhydrous and be unable to complete liquid conveying task or the fire that disappears the case where taking precautions against natural calamities in order to prevent, into
One step, pressure-detecting device provided herein can also include hydraulic pressure force value prior-warning device, hydraulic pressure force value prior-warning device
It is electrically connected with pressure-detecting device and data transmission device, hydraulic pressure force value prior-warning device may include that the third interconnected is sentenced
Disconnected element and third control element；In the course of work of pressure monitoring devices, third judgment component may determine that pressure detecting
Whether hydraulic pressure force value measured by device is greater than preset upper pressure limit value, and/or whether is less than preset low pressure limit
Value, and judging result is exported to third control element；Correspondingly, it is greater than in aforementioned pressure in measured actual hydraulic pressure force value
Limit value, or be less than aforementioned pressure lower limit value when, third control element can control data transmission device transmit the second warning message.
Specifically, similarly with over range prior-warning device, hydraulic pressure force value prior-warning device is by judging water measured by pressure-detecting device
The size of pressure value, if the value beyond preset pressure bound, and in measured hydraulic pressure force value beyond above and below pressure
When limit value, data transmission device is controlled by the second control element and transmits the second warning message, staff is receiving second
When warning message, the hydraulic pressure force value at available pipe under test transfinites this information, then can suitably be subtracted according to the information
Flow that is small or increasing liquid at pipe under test, realization remotely monitor and solve the problems, such as that pressure limit or pressure are inadequate,
Further, for the transmission working efficiency of improve data transfer device, and in order to reduce data transmission device
The number of starts, to improve its service life, it is preferred that pressure-detecting device provided herein can also include that second prolong
When control device, the second overrun control can be electrically connected with data transmission device, and the second overrun control may include
Second time detecting element, the 4th judgment component and the 4th control element, and three is electrically connected to each other, the second time control components
It can detecte the second duration that data transmission device is under stop working state, and the second duration exported to the 4th judgement member
Part to judge whether the second duration is equal to the second preset duration by the 4th judgment component, and is equal to second in advance in the second duration
If when duration, controlling data transmission device by the 4th control element and entering working condition, that is, carry out to measured number pressure
According to transmission work.Specifically, the second overrun control may be the devices such as time-delay relay, pass through the second delay of setting
Control device makes data transmission device also can periodic duty；Those skilled in the art can period determines according to actual conditions
The size of value, specifically, the value of the second preset duration can be greater than or equal to the first preset duration, and preferably the second preset duration is big
In the first preset duration, more specifically, when data transmission device is in and stops working, pressure-detecting device can will be measured
Hydraulic pressure force value be buffered in data transmission device, when data upload the period reach when, data transmission device can will before deposit
Storage multiple groups hydraulic pressure force value (i.e. different time points when pipeline in hydraulic pressure force value) data transfer out, data biography can be improved in this
The working efficiency of defeated device, and the service life of data transmission device can be extended, can also extend battery uses the time.
Further, it is contemplated that data transmission device may be caused to cannot proceed normally data biography because of factors such as network fluctuations
Defeated work causes the imperfection of data, it is preferable that this Shen to cause staff that can not understand and record the secondary data
It please be also provided with upload monitoring device in provided pressure monitoring devices, upload monitoring device and data transmission device electricity
Connection, is used for whether detection data transmitting device successfully to transfer out by data and (be such as transmitted to monitoring system), and, when
When data transmission device can not carry out data transmission work, upload monitoring device can recorde tool when such as this time data transmission
The body moment, failure cause etc., and control data transmission device itself or other devices will be under the data storages of transmission needed for this
Come, when data transmission device carries out data transmission work next time, upload monitoring device controls data transmission device again will be upper
The data of secondary non-transmission success and this time the data sent is needed to transfer out together；Alternatively, in some cases, can control
Data transmission device processed successively transfers out the data of this and last time.
